      of this clause (ii) such person shall be deemed to have "beneficial
      ownership" of all shares that any such person has the right to acquire,

      directly or indirectly, in the aggregate a lesser percentage of the voting

      of Holdings was approved by a vote of 66 2/3% of the directors of Holdings
      then still in office who were either directors at the beginning of such
      period or whose election or nomination for election was previously so
      approved) cease for any reason to constitute a majority of the Board of
      Directors of Holdings then in office; or



                                                                               5

            (iv) the merger or consolidation of Holdings with or into another
      Person or the merger of another Person with or into Holdings, or the sale
      of all or substantially all the assets of Holdings to another Person
      (other than a Person that is controlled by the Permitted Holders), and, in
      the case of any such merger or consolidation, the securities of Holdings
      that are outstanding immediately prior to such transaction and which
      represent 100% of the aggregate voting power of the Voting Stock of
      Holdings are changed into or exchanged for cash, securities or property,
      unless pursuant to such transaction such securities are changed into or
      exchanged for, in addition to any other consideration, securities of the
      surviving Person that represent immediately after such transaction, at
      least a majority of the aggregate voting power of the Voting Stock of the
      surviving Person; provided, however, that any sale of accounts receivable
      in connection with a Qualified Receivables Transaction shall not
      constitute a Change of Control.

            "Closing Date" means the date of this Indenture.

            "Code" means the Internal Revenue Code of 1986, as amended.

            "Company" means WESCO Distribution, Inc., a Delaware corporation and

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
Holdings 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

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 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 Holdings or such Restricted Subsidiary has
not earned the interest income actually earned during such



                                                                               6

equal to the Consolidated Interest Expense directly attributable to any
Indebtedness of Holdings or any Restricted Subsidiary repaid, repurchased,
defeased or otherwise discharged with respect to Holdings 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

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 Holdings, and such pro forma calculations
shall include (A)(x) the savings in cost of goods sold that would have resulted
from using Holdings' actual costs for comparable goods and services during the

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 Holdings 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).

      Indebtedness;

            (7) the principal amount of any noninterest bearing or other

                           The Senior Discount Notes

            SECTION 2.01. Form and Dating. Provisions relating to the Initial
Senior Discount Notes, the Private Senior Discount Exchange Notes and the Senior
Discount Exchange Notes are set forth in the Appendix, which is hereby
incorporated in and expressly made a part of this Indenture. The (i) Initial
Senior Discount Notes and the Senior Discount Notes Trustee's certificate of
authentication and (ii) Private Senior Discount Exchange Notes and the Senior
Discount 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 Discount Exchange Notes
and the Senior Discount Notes Trustee's certificate of authentication shall be
substantially in the form of Exhibit B hereto, which is hereby incorporated in



                                                                              23

and expressly made a part of this Indenture. The Senior Discount Notes may have
notations, legends or endorsements required by law, stock exchange rule,
agreements to which Holdings is subject, if any, or usage (provided that any
such notation, legend or endorsement is in a form acceptable to Holdings). Each
Senior Discount Note shall be dated the date of its authentication. The Senior
Discount Notes shall be issued only in registered form without coupons and only
in denominations of $1,000 (in principal amount at maturity) and integral
multiples thereof.

            SECTION 2.02. Execution and Authentication. One or more Officers
shall sign the Senior Discount Notes for Holdings by manual or facsimile
signature.

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

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

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

            The Senior Discount Notes Trustee may appoint an authenticating
agent reasonably acceptable to Holdings to authenticate the Senior Discount
Notes. Any such appointment shall be evidenced by an instrument signed by a
Trust Officer, a copy of which shall be furnished to Holdings. Unless limited by
the terms of such appointment, an authenticating agent may authenticate Senior
Discount Notes whenever the Senior Discount Notes Trustee may do so. Each
reference in this Indenture to authentication by the Senior Discount 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 2.03. Registrar and Paying Agent. Holdings shall maintain an
office or agency where Senior Discount Notes may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Senior Discount Notes may be presented for payment (the "Paying Agent"). The
Registrar shall keep a register of the Senior Discount Notes and of their
transfer and exchange. Holdings 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. Holdings
initially appoints the Senior Discount Notes Trustee as (i) Registrar and Paying
Agent in connection with the Senior Discount Notes and (ii) the Senior Discount
Notes Custodian (as defined in the Appendix) with respect to the Global Senior
Discount Notes (as defined in the Appendix).

            Holdings 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. Holdings shall notify the Senior Discount
Notes Trustee of the name and address of any such agent. If Holdings fails to
maintain a Registrar or Paying Agent, the Senior Discount Notes Trustee shall
act as such and shall be entitled to appropriate



                                                                              24

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

            Holdings may remove any Registrar or Paying Agent upon written
notice to such Registrar or Paying Agent and to the Senior Discount 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 Holdings and such successor Registrar or Paying Agent,
as the case may be, and delivered to the Senior Discount Notes Trustee or (2)
notification to the Senior Discount Notes Trustee that the Senior Discount 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
Discount Notes Trustee may resign as Paying Agent or Registrar only if the
Senior Discount Notes Trustee also resigns as Senior Discount Notes Trustee in
accordance with Section 7.08.

            SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due
date of the principal and interest on any Senior Discount Note, Holdings shall
deposit with the Paying Agent (or if Holdings 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. Holdings shall require each Paying Agent (other than the Senior
Discount Notes Trustee) to agree in writing that the Paying Agent shall hold in
trust for the benefit of Senior Discount Noteholders or the Senior Discount
Notes Trustee all money held by the Paying Agent for the payment of principal of
or interest on the Senior Discount Notes and shall notify the Senior Discount
Notes Trustee of any default by Holdings in making any such payment. If Holdings
or a Subsidiary of Holdings acts as Paying Agent, it shall segregate the money
held by it as Paying Agent and hold it as a separate trust fund. Holdings at any
time may require a Paying Agent to pay all money held by it to the Senior
Discount 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 Discount Notes Trustee.

            SECTION 2.05. Senior Discount Noteholder Lists. The Senior Discount
Notes Trustee shall preserve in as current a form as is reasonably practicable
the most recent list available to it of the names and addresses of Senior
Discount Noteholders. If the Senior Discount Notes Trustee is not the Registrar,
Holdings shall furnish, or cause the Registrar to furnish, to the Senior
Discount Notes Trustee, in writing at least five Business Days before each
interest payment date and at such other times as the Senior Discount Notes
Trustee may request in writing, a list in such form and as of such date as the
Senior Discount Notes Trustee may reasonably require of the names and addresses
of Senior Discount Noteholders.

            SECTION 2.06. Transfer and Exchange. The Senior Discount Notes shall
be issued in registered form and shall be transferable only upon the surrender
of a Senior Discount Note for registration of transfer and in compliance with
the Appendix. When a Senior Discount 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 Senior Discount Notes are presented to the Registrar with a
request to exchange them for an equal principal amount at maturity of Senior
Discount Notes of other denominations, the



                                                                              25

Registrar shall make the exchange as requested if the same requirements are met.
To permit registration of transfers and exchanges, Holdings shall execute and
the Senior Discount Notes Trustee shall authenticate Senior Discount Notes at
the Registrar's request. Holdings 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. Holdings shall not be required to
make and the Registrar need not register transfers or exchanges of Senior
Discount Notes selected for redemption (except, in the case of Senior Discount
Notes to be redeemed in part, the portion thereof not to be redeemed) or any
Senior Discount Notes for a period of 15 days before a selection of Senior
Discount Notes to be redeemed.

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

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

            All Senior Discount 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 Discount Notes
surrendered upon such transfer or exchange.

            SECTION 2.07. Replacement Senior Discount Notes. If a mutilated
Senior Discount Note is surrendered to the Registrar or if the Senior Discount
Noteholder of a Senior Discount Note claims that the Senior Discount Note has
been lost, destroyed or wrongfully taken, Holdings shall issue and the Senior
Discount Notes Trustee shall authenticate a replacement Senior Discount Note if
the requirements of Section 8-405 of the Uniform Commercial Code are met, such
that the Senior Discount Noteholder (i) satisfies Holdings or the Senior
Discount 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
Holdings or the Senior Discount Notes Trustee prior to the Senior Discount 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 Discount Notes Trustee. If required by the
Senior Discount Notes Trustee or Holdings, such Senior Discount Noteholder shall
furnish an indemnity bond sufficient in the judgment of the Senior Discount
Notes Trustee to protect Holdings, the Senior Discount Notes Trustee, the Paying
Agent and the Registrar from any loss that any of them may suffer if a Senior
Discount Note is replaced. Holdings and the Senior Discount Notes Trustee may
charge the Senior Discount Noteholder for their expenses in replacing a



                                                                              26

Senior Discount Note. In the event any such mutilated, lost, destroyed or
wrongfully taken Senior Discount Note has become or is about to become due and
payable, Holdings in its discretion may pay such Senior Discount Note instead of
issuing a new Senior Discount Note in replacement thereof.

            Every replacement Senior Discount Note is an additional obligation
of Holdings.

            The provisions of this Section 2.07 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
Discount Notes.

            SECTION 2.08. Outstanding Senior Discount Notes. Senior Discount
Notes outstanding at any time are all Senior Discount Notes authenticated by the
Senior Discount 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 Discount Note does not cease to be outstanding because Holdings or an
Affiliate of Holdings holds the Senior Discount Note.

            If a Senior Discount Note is replaced pursuant to Section 2.07, it
ceases to be outstanding unless the Senior Discount Notes Trustee and Holdings
receive proof satisfactory to them that the replaced Senior Discount 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
Discount Notes (or portions thereof) to be redeemed or maturing, as the case may
be, then on and after that date such Senior Discount Notes (or portions thereof)
cease to be outstanding and interest on them ceases to accrue.

            SECTION 2.09. Temporary Senior Discount Notes. In the event that
Definitive Senior Discount Notes (as defined in the Appendix) are to be issued
under the terms of this Indenture, until such Definitive Senior Discount Notes
are ready for delivery, Holdings may prepare and the Senior Discount Notes
Trustee shall authenticate temporary Senior Discount Notes. Temporary Senior
Discount Notes shall be substan tially in the form of Definitive Senior Discount
Notes but may have variations that Holdings considers appropriate for temporary
Senior Discount Notes. Without unreasonable delay, Holdings shall prepare and
the Senior Discount Notes Trustee shall authenticate Definitive Senior Discount
Notes and deliver them in exchange for temporary Senior Discount Notes upon
surrender of such temporary Senior Discount Notes at the office or agency of
Holdings, without charge to the Senior Discount Noteholder.

            SECTION 2.10. Cancelation. Holdings at any time may deliver Senior
Discount Notes to the Senior Discount Notes Trustee for cancelation. The
Registrar and the Paying Agent shall forward to the Senior Discount Notes
Trustee any Senior Discount Notes surrendered to them for registration of
transfer, exchange or payment. The Senior Discount Notes Trustee and no one else
shall cancel all Senior Discount Notes surrendered for registration of transfer,
exchange, payment or cancelation and deliver canceled Senior Discount Notes to
Holdings pursuant to written direction by an



                                                                              27


Officer. Holdings may not issue new Senior Discount Notes to replace Senior
Discount Notes it has redeemed, paid or delivered to the Senior Discount Notes
Trustee for cancelation. The Senior Discount Notes Trustee shall not
authenticate Senior Discount Notes in place of canceled Senior Discount Notes
other than pursuant to the terms of this Indenture.

            SECTION 2.11. Defaulted Interest. If Holdings defaults in a payment
of interest on the Senior Discount Notes, Holdings shall pay the defaulted
interest (plus interest on such defaulted interest at the rate of 111/8% per
annum to the extent lawful) in any lawful manner. Holdings may pay the defaulted
interest to the Persons who are Senior Discount Noteholders on a subsequent
special record date. Holdings shall fix or cause to be fixed any such special
record date and payment date to the reasonable satisfaction of the Senior
Discount Notes Trustee and shall promptly mail or cause to be mailed to each
Senior Discount Noteholder a notice that states the special record date, the
payment date and the amount of defaulted interest to be paid.

            SECTION 2.12. CUSIP Numbers. Holdings in issuing the Senior Discount
Notes may use "CUSIP" numbers (if then generally in use) and, if so, the Senior
Discount Notes Trustee shall use "CUSIP" numbers in notices of redemption as a
convenience to Senior Discount 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 Discount 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 Discount 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 Discount Notes Trustee. If Holdings
elects to redeem Senior Discount Notes pursuant to paragraph 5 of the Senior
Discount Notes, it shall notify the Senior Discount Notes Trustee in writing of
the redemption date and the principal amount at maturity of Senior Discount
Notes to be redeemed.

            Holdings shall give each notice to the Senior Discount Notes Trustee
provided for in this Section at least 60 days before the redemption date unless
the Senior Discount Notes Trustee consents to a shorter period. Such notice
shall be accompanied by an Officers' Certificate and an Opinion of Counsel from
Holdings to the effect that such redemption will comply with the conditions
herein. If fewer than all the Senior Discount Notes are to be redeemed, the
record date relating to such redemption shall be selected by Holdings and given
to the Senior Discount Notes Trustee, which record date shall be not fewer than
15 days after the date of notice to the Senior Discount Notes Trustee. Any such
notice may be canceled at any time prior to notice of such redemption being
mailed to any Senior Discount Noteholder and shall thereby be void and of no
effect.

            SECTION 3.02. Selection of Senior Discount Notes To Be Redeemed. (a)
If the mandatory redemption of Senior Discount Notes pursuant to paragraph 9 of
the Senior Discount Notes would result in an outstanding Senior Discount Note in
a


                                                                              28


denomination (i) of less than $1,000 principal amount at maturity or (ii) other
than an integral multiple of $1,000 principal amount at maturity, such Senior
Discount Note will be redeemed (A) in whole, in the case of clause (i), or (B)
by an additional amount so that such Senior Discount Note will be in a
denomination of an integral multiple of $1,000 principal amount at maturity, in
the case of clause (ii).

            (b) If fewer than all the Senior Discount Notes are to be redeemed
pursuant to paragraph 5 of the Senior Discount Notes, the Senior Discount Notes
Trustee shall select the Senior Discount Notes to be redeemed pro rata or by
lot. The Senior Discount Notes Trustee shall make the selection from outstanding
Senior Discount Notes not previously called for redemption. The Senior Discount
Notes Trustee may select for redemption pursuant to paragraph 5 of the Senior
Discount Notes portions of the principal of Senior Discount Notes that have
denominations larger than $1,000 (at maturity) Senior Discount Notes and
portions of them the Senior Discount Notes Trustee selects shall be in amounts
of $1,000 (in principal amount at maturity) or a whole multiple of $1,000.
Provisions of this Indenture that apply to Senior Discount Notes called for
redemption also apply to portions of Senior Discount Notes called for
redemption. The Senior Discount Notes Trustee shall notify Holdings promptly of
the Senior Discount Notes or portions of Senior Discount 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 Discount Notes, Holdings
shall mail a notice of redemption by first-class mail to each Senior Discount
Noteholder of Senior Discount Notes to be redeemed at such Senior Discount
Noteholder's registered address.

            The notice shall identify the Senior Discount 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 Discount Notes called for redemption must be
      surrendered to the Paying Agent to collect the redemption price;

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

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

            (7) the paragraph of the Senior Discount Notes pursuant to which the
      Senior Discount Notes called for redemption are being redeemed;


                                                                              29


            (8) the CUSIP number, if any, printed on the Senior Discount Notes
      being redeemed;

            (9) 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 Discount Notes; and

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

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

            SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Senior Discount 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 Discount 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 Discount Noteholder of the redeemed
Senior Discount Notes registered on the relevant record date. Failure to give
notice or any defect in the notice to any Senior Discount Noteholder shall not
affect the validity of the notice to any other Senior Discount Noteholder.

            SECTION 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. on
the redemption date, Holdings shall deposit with the Paying Agent (or, if
Holdings 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 Discount Notes to be redeemed on that date other than Senior Discount
Notes or portions of Senior Discount Notes called for redemption that have been
delivered by Holdings to the Senior Discount Notes Trustee for cancelation.

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

promptly pay the principal of and interest (and Accreted Value, if applicable)
on the Senior Discount Notes on the dates and in the manner provided in the
Senior Discount Notes and in this Indenture. Principal and interest (and
Accreted Value, if applicable) shall be considered paid on the date due if on
such date the Senior Discount Notes


                                                                              30


Trustee or the Paying Agent holds in accordance with this Indenture money
sufficient to pay all principal and interest (and Accreted Value, if applicable)
then due and the Senior Discount Notes Trustee or the Paying Agent, as the case
may be, is not prohibited from paying such money to the Senior Discount
Noteholders on that date pursuant to the terms of this Indenture.

            Holdings shall pay interest on overdue principal at the rate
specified therefor in the Senior Discount 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 Holdings may not be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, Holdings shall file with the SEC and provide the Senior Discount Notes

Senior Discount Noteholder) with such annual reports and such information,

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) Holdings shall not,
and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that Holdings and 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), Holdings 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

      Indebtedness is expressly subordinated to the prior payment in full in
      cash of all obligations with respect to the Senior Discount Notes;

      the Senior Subordinated Notes (not including any Additional Senior

      Refinancing Indebtedness Incurred in respect of any Indebtedness described
      in this


                                                                              31

      transactions pursuant to which such Restricted Subsidiary became a
      Subsidiary of or was otherwise acquired by Holdings); 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 Holdings, Holdings 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 a Restricted
      Subsidiary in respect of Indebtedness Incurred by such Restricted
      Subsidiary pursuant to this clause (iv);

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

            (vi) Indebtedness Incurred by Holdings 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 Holdings or the Company in connection

      clause (vii) shall not exceed $50.0 million at any one time;

            (viii) Attributable Debt Incurred by Holdings or the Company in

      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 Holdings or a
      Restricted Subsidiary providing for indemnification, purchase price
      adjustment or similar


                                                                              32


      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 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 Holdings and its Restricted Subsidiaries in
      connection with such disposition;

            (x) any Guarantee by Holdings of Indebtedness or other obligations

      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) Notwithstanding any other provision of this Section 4.03, the
maximum amount of Indebtedness that Holdings 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
Indebtedness and (ii) in the event that Indebtedness meets the criteria of more
than one of the types of Indebtedness described in this Section, Holdings, 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.

redeem, retire or otherwise acquire for value any Capital Stock of Holdings or
any Restricted Subsidiary held by Persons other than Holdings or another
Restricted Subsidiary, (iii) purchase, repurchase, redeem, defease or otherwise

repurchase or other acquisition of Subordinated Obligations of Holdings
purchased in anticipation of satisfying a sinking fund obligation, principal
installment or final maturity, in each case due within one year of the date of
acquisition) or (iv) make any Investment (other than a Permitted Investment) in
any Person (any such dividend, distribution, purchase, redemption, repurchase,
defeasance, other acquisition, retirement or Investment being herein referred to

      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
            Income will be a deficit, minus 100% of such deficit);

                  (B) the aggregate Net Cash Proceeds or fair market value of

            subsequent to the Closing Date (other than an issuance or sale to
            (x) a Subsidiary of Holdings or (y) an employee stock ownership plan
            or other trust established by Holdings or any of its Subsidiaries);

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

                  (D) the amount equal to the net reduction in Investments in
            any Person (other than a Restricted Subsidiary) resulting from (i)
            payments of dividends, repayments of the principal of loans or
            advances or other

            transfers of assets to Holdings or any Restricted Subsidiary from
            such Person, (ii) the sale or liquidation for cash of such
            Investment or (iii) the redesignation of Unrestricted Subsidiaries
            as Restricted Subsidiaries (valued in each case as provided in the

            Unrestricted Subsidiary, the amount of Investments previously made
            by Holdings 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
      Holdings (other than Disqualified Stock and other than Capital Stock
      issued or sold to a Subsidiary of Holdings or an employee stock ownership
      plan or other trust established by Holdings 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);

            (ii) any purchase, repurchase, redemption, defeasance or other

      Incurred pursuant to Section 4.03(b); provided, however, that such
      purchase, repurchase, redemption, defeasance or other acquisition or
      retirement for value shall be excluded in the calculation of the amount of
      Restricted Payments;

            (iii) any purchase or redemption of Subordinated Obligations of

            (iv) dividends paid within 60 days after the date of declaration
      thereof if at such date of declaration such dividend would have complied
      with Section 4.04(a); provided, however, that such dividend shall be
      included in the calculation of the amount of Restricted Payments;

            (v) any Restricted Payment made for the repurchase, redemption or
      other acquisition or retirement for value of any Capital Stock of Holdings
      or any Restricted Subsidiaries held by any employee, former employee,
      director or former director of Holdings or any of its Subsidiaries (and
      any permitted transferees thereof) pursuant to any equity subscription
      agreement, stock option agreement or plan or other similar agreement;
      provided, however, that the aggregate amount of such Restricted Payments
      shall not exceed $5.0 million in any calendar year and $20.0 million in
      the aggregate; provided further, however, that such Restricted Payments
      shall be included in the calculation of the amount of Restricted Payments;


                                                                              35


             (vi) following the initial Equity Offering by Holdings, any payment
      of dividends or common stock buybacks by Holdings in an aggregate amount
      in any year not to exceed 6% of the aggregate Net Cash Proceeds actually
      received by Holdings in connection with such initial Equity Offering and
      any subsequent Equity Offering by Holdings; provided, however, that no
      Default or Event of Default shall have occurred and be continuing
      immediately before or after any such payment; provided further, however,
      that such dividends or common stock buybacks shall be included in the
      calculation of the amount of Restricted Payments;

            (vii) 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;

            (viii) the declaration and payment of dividends to holders of any
      class or series of Disqualified Stock of Holdings issued in accordance
      with Section 4.03(b) to the extent such dividends are included in the
      definition of Consolidated Interest Expense; provided, however, that such
      dividends shall be included in the calculation of the amount of Restricted
      Payments;

            (ix) Investments made with Excluded Contributions; provided,
      however, that such Investments shall be excluded in the calculation of the
      amount of Restricted Payments;

            (x) any Restricted Payment made to fund the Recapitalization
      (including fees and expenses); provided, however, that such Restricted
      Payment shall be excluded in the calculation of the amount of Restricted

            SECTION 4.05. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. Holdings shall not, and shall not permit any Restricted
Subsidiary to, create or otherwise cause or permit to exist or become effective
any consensual encumbrance or restriction on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions on its Capital
Stock or pay any Indebtedness or other obligations owed to Holdings, (ii) make
any loans or advances to Holdings or (iii) transfer any of its property or
assets to Holdings, except:

            (1) any encumbrance or restriction pursuant to an agreement in
      effect at or entered into on the Closing Date;

            (2) any encumbrance or restriction with respect to a Restricted
      Subsidiary pursuant to an agreement relating to any Indebtedness Incurred

      which such Restricted Subsidiary became a Restricted Subsidiary or was
      otherwise acquired by Holdings) and outstanding on such date;

            (3) any encumbrance or restriction pursuant to an agreement
      effecting a Refinancing of Indebtedness Incurred pursuant to an agreement
      referred to in clause (1) or (2) of this Section 4.05 or this clause (3)
      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 Discount Noteholders than
      the encumbrances and restrictions contained in such predecessor
      agreements;

            (4) in the case of clause (iii), any encumbrance or restriction (A)
      that restricts in a customary manner the subletting, assignment or
      transfer of any property or asset that is subject to a lease, license or
      similar contract, (B) contained in security agreements or mortgages
      securing Indebtedness of a Restricted Subsidiary to the extent such

      purchase money obligations for property acquired in the ordinary course of
      business;

            (5) with respect to a Restricted Subsidiary, any restriction imposed

      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 Discount
      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) Holdings shall not, and shall not permit any Restricted Subsidiary to, make
any Asset Disposition unless (i) Holdings 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 Holdings) of the shares and assets subject to such Asset
Disposition, (ii) at least 75% of the consideration thereof received by Holdings
or such Restricted Subsidiary is in the form of cash or cash equivalents
(provided that the amount of (w) any liabilities (as shown on Holdings' or such
Restricted Subsidiary's most recent balance sheet or in the notes thereto) of
Holdings or any Restricted Subsidiary (other than liabilities that are by their
terms subordinated to the Senior Discount Notes) that are assumed by the
transferee of any such assets without recourse to Holdings or any of the
Restricted Subsidiaries, (x) any notes or other obligations received by Holdings
or such Restricted Subsidiary from such transferee that are converted by
Holdings or such Restricted Subsidiary into cash (to the


                                                                              37


extent of the cash received) within 180 days following the closing of such Asset
Disposition, (y) any Designated Noncash Consideration received by Holdings 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 Disposition is
applied by Holdings (or such Restricted Subsidiary, as the case may be) (A)
first, to the extent Holdings elects (or is required by the terms of any
Indebtedness), to prepay, repay, redeem or purchase 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 Holdings or an
Affiliate of Holdings) 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 Holdings 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 Holdings 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 Discount
Notes pursuant to and subject to the conditions of Section 4.06(b); provided,
however, that if Holdings elects (or is required by the terms of any other
Senior Indebtedness of Holdings), such Offer may be made ratably to purchase the
Senior Discount Notes and other Senior Indebtedness of Holdings; provided,
however, that in connection with any prepayment, repayment or purchase of
Indebtedness pursuant to clause (A) or (C) above, Holdings 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, Holdings 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 Discount Notes (and other Senior Indebtedness of Holdings) pursuant to
Section 4.06(a)(iii)(C), Holdings shall be required to purchase Senior Discount
Notes (and other Senior Indebtedness of Holdings) tendered pursuant to an offer
by Holdings for the Senior Discount Notes (and other Senior Indebtedness of
Holdings) (the "Offer") at a purchase price of (a) 100% of the Accreted Value
thereof at the date of purchase plus liquidated damages thereon, if any, to the
date of purchased, if purchased on or prior to June 1, 2003, and (b) 100% of the
principal amount thereof plus accrued and unpaid interest and liquidated
damages, if any, to the date of purchase, if purchased after June 1, 2003, in
each case 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 Discount Notes (and other Senior Indebtedness of Holdings) tendered
pursuant to the


                                                                              38


Offer is less than the Net Available Cash allotted to the purchase of the Senior
Discount Notes (and other Senior Indebtedness of Holdings), Holdings may apply
the remaining Net Available Cash for any purpose permitted by the terms of this
Indenture. Holdings shall not be required to make an Offer for Senior Discount
Notes (and other Senior Indebtedness of Holdings) 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).

            (c) (1) Promptly, and in any event within 30 days after Holdings
becomes obligated to make an Offer, Holdings shall be obligated to deliver to
the Senior Discount Notes Trustee and send, by first-class mail to each Senior
Discount Noteholder, a written notice stating that the Senior Discount
Noteholder may elect to have his Senior Discount Notes purchased by Holdings
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 maturity, 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 Holdings which Holdings in good faith
believes will enable such Senior Discount Noteholders to make an informed
decision and all instructions and materials necessary to tender Senior Discount
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 Discount Notes Trustee as provided above, Holdings shall
deliver to the Senior Discount 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, Holdings shall also irrevocably deposit with the Senior
Discount Notes Trustee or with a paying agent (or, if Holdings 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"), Holdings shall
deliver to the Senior Discount Notes Trustee for cancelation the Senior Discount
Notes or portions thereof that have been properly tendered to and are to be
accepted by Holdings. The Senior Discount Notes Trustee (or the Paying Agent, if
not the Senior Discount Notes Trustee) shall, on the date of purchase, mail or
deliver payment to each tendering Senior Discount Noteholder in the amount of
the purchase price. In the event that the aggregate purchase price of the Senior
Discount Notes (and other Senior Indebtedness of Holdings) delivered by Holdings
to the Senior Discount Notes Trustee is less than the Offer Amount applicable to
the Senior Discount Notes (and other Senior Indebtedness of Holdings), the
Senior Discount Notes Trustee shall deliver the excess to Holdings immediately
after the expiration of the Offer Period for application in accordance with this
Section 4.06.

            (3) Senior Discount Noteholders electing to have a Senior Discount
Note purchased shall be required to surrender the Senior Discount Note, with an
appropriate form duly completed, to Holdings at the address specified in the
notice at least three Business Days prior to the Purchase Date. Senior Discount
Noteholders shall be entitled


                                                                              39


to withdraw their election if the Senior Discount Notes Trustee or Holdings
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
Discount Noteholder, the principal amount at maturity of the Senior Discount
Note which was delivered by the Senior Discount Noteholder for purchase and a
statement that such Senior Discount Noteholder is withdrawing his election to
have such Senior Discount Note purchased. If at the expiration of the Offer
Period the aggregate principal amount (or Accreted Value, if applicable) of
Senior Discount Notes and any other Senior Indebtedness of Holdings included in
the Offer surrendered by holders thereof exceeds the Offer Amount, Holdings
shall select the Senior Discount Notes and other Senior Indebtedness of Holdings
to be purchased on a pro rata basis (with such adjustments as may be deemed
appropriate by Holdings so that only Senior Discount Notes and other Senior
Indebtedness of Holdings in denominations of $1,000 (principal amount at
maturity), or integral multiples thereof, shall be purchased). Senior Discount
Noteholders whose Senior Discount Notes are purchased only in part will be
issued new Senior Discount Notes equal in principal amount at maturity to the
unpurchased portion of the Senior Discount Notes surrendered.

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

            (d) Holdings 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 Discount Notes
pursuant to this Section. To the extent that the provisions of any securities
laws or regulations conflict with provisions of this Section, Holdings 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) Holdings 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 Holdings or
the relevant Restricted Subsidiary than those that would have been obtained in a
comparable transaction by Holdings 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, Holdings delivers to the Senior Discount 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


                                                                              40


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 Holdings 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 Holdings,
but in any event not to exceed $5.0 million in the aggregate outstanding at any
one time, (v) the payment of reasonable fees to directors of Holdings and its
Restricted Subsidiaries who are not employees of Holdings or its Subsidiaries,
(vi) any transaction between Holdings and a Restricted Subsidiary or between
Restricted Subsidiaries, (vii) any transaction effected as part of a Qualified
Receivables Transaction, (viii) indemnification agreements with, and the payment
of fees and indemnities to, directors, officers and employees of Holdings and
its Restricted Subsidiaries, in each case, in the ordinary course of business,
(ix) any employment, compensation, noncompetition or confidentiality agreement
entered into by Holdings and its Restricted Subsidiaries with its employees in
the ordinary course of business, (x) the payment by Holdings of fees, expenses
and other amounts to Cypress and its Affiliates in connection with the
Recapitalization, (xi) payments by Holdings 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, (xii) any issuance of Capital Stock of Holdings (other
than Disqualified Stock), (xiii) 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
Discount Noteholders of the Senior Discount Notes in any material respect than
the original agreement as in effect on the Closing Date and (xiv) transactions
in which Holdings or any of its Restricted Subsidiaries, as the case may be,
delivers to the Senior Discount Notes Trustee a letter from an Independent
Financial Advisor stating that such transaction is fair to Holdings 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 Discount Notes have been called for redemption
pursuant to paragraph 5 of the Senior Discount Notes, each Senior Discount
Noteholder shall have the right to require Holdings to repurchase all or any
part of such Senior Discount Noteholder's Senior Discount Notes at a purchase
price in cash equal to (a) 101% of the Accreted Value thereof at the date of
repurchase plus liquidated damages thereon, if any, to the date of repurchase,
if repurchased on or prior to June 1, 2003, and (b) 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 Discount Noteholders of
record on the relevant record date to receive interest due on the relevant
interest payment date), if repurchased after June 1, 2003, in each case 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 Holdings
becomes aware that a Change of Control has occurred, if the purchase of the
Senior Discount Notes would violate or constitute a default under any other
Indebtedness of Holdings or its Subsidiaries, or not be permitted by (including
because Subsidiaries of Holdings could not provide adequate funds therefor),
then Holdings shall and shall cause its Subsidiaries, to the extent needed to
permit such purchase of Senior Discount Notes, either (i) to 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 Discount Notes as provided below. Until such
time as Holdings is able to repay


                                                                              41


all such Indebtedness and terminate all commitments outstanding thereunder or
such time as such requisite consents are obtained, Holdings shall not be
required to make the Change of Control Offer or purchase the Senior Discount
Notes pursuant to the provisions described below.

            (b) Within 30 days following any Change of Control, unless all
Senior Discount Notes have been called for redemption pursuant to paragraph 5 of
the Senior Discount Notes, Holdings shall mail a notice to each Senior Discount
Noteholder with a copy to the Senior Discount Notes Trustee (the "Change of
Control Offer") stating:

            (1) that a Change of Control has occurred and that such Senior
      Discount Noteholder has the right to require Holdings to purchase such
      Senior Discount Noteholder's Senior Discount Notes at a purchase price in
      cash equal to (a) 101% of the Accreted Value thereof at the date of
      repurchase plus liquidated damages thereon if any, to the date of
      repurchase, if repurchased on or prior to June 1, 2003, and (b) 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 Discount Noteholders of record on the relevant record date
      to receive interest on the relevant interest payment date), if repurchased
      after June 1, 2003;

            (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 Holdings, consistent with this
      Section, that a Senior Discount Noteholder must follow in order to have
      its Senior Discount Notes repurchased.

            (c) Senior Discount Noteholders electing to have a Senior Discount
Note repurchased shall be required to surrender the Senior Discount Note, with
an appropriate form duly completed, to Holdings at the address specified in the
notice at least three Business Days prior to the repurchase date. Senior
Discount Noteholders shall be entitled to withdraw their election if the Senior
Discount Notes Trustee or Holdings 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 Discount Noteholder, the principal amount
at maturity of the Senior Discount Note which was delivered for repurchase by
the Senior Discount Noteholder and a statement that such Senior Discount
Noteholder is withdrawing his election to have such Senior Discount Note
repurchased.

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

            (e) Notwithstanding the foregoing provisions of this Section,
Holdings 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


                                                                              42


of Control Offer made by Holdings and purchases all Senior Discount Notes
validly tendered and not withdrawn under such Change of Control Offer.

            (f) Holdings 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 Discount Notes
pursuant to this Section. To the extent that the provisions of any securities
laws or regulations conflict with provisions of this Section, Holdings 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. Holdings shall deliver to the
Senior Discount Notes Trustee within 120 days after the end of each fiscal year
of Holdings an Officers' Certificate stating that a review of Holdings'
activities during the preceding fiscal year has been made under the supervision
of the signing Officers with a view to determining whether Holdings 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 Holdings 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 Holdings 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 Holdings is taking or
proposes to take with respect thereto. Holdings also shall comply with Section
314(a)(4) of the TIA.

            SECTION 4.10. Further Instruments and Acts. Upon request of the
Senior Discount 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 4.11. Limitation on the Sale or Issuance of Capital Stock of
Restricted Subsidiaries. Holdings 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 Holdings 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 Holdings 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. Holdings shall not directly or
indirectly Incur or permit to exist any Lien that secures Indebtedness of
Holdings of any


                                                                              43


nature whatsoever 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 Discount Notes shall be secured equally and ratably with (or on a senior
basis to in the case of Subordinated Obligations of Holdings) the obligations so
secured for so long as such obligations are so secured.

      Columbia and the Successor Company (if not Holdings) shall expressly
      assume, by an indenture supplemental hereto, executed and delivered to the
      Senior Discount Notes Trustee, in form satisfactory to the Senior Discount
      Notes Trustee, all the obliga tions of Holdings under the Senior Discount
      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 Holdings 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 Holdings immediately prior to

substantially all its assets shall not be released from the obligation to pay
the principal of and interest on the Senior Discount Notes.


                                                                              44


            Notwithstanding clause (iii) above, a Wholly Owned Subsidiary may be
consolidated with or merged into Holdings and Holdings may consolidate with or
merge with or into 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 Holdings.

                              Defaults and Remedies

      exceeds $25 million or its foreign currency equivalent at the time and
      such failure continues for 10 days after the notice specified below;

            (7) Holdings 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

            (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
      Holdings 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.

            A Default under clause (4), (5), (6) or (9) above is not an Event of
Default until the Senior Discount Notes Trustee or the Senior Discount
Noteholders of at least 25% in principal amount at maturity of the outstanding
Senior Discount Notes notify Holdings of the Default and Holdings 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".

            Holdings shall deliver to the Senior Discount 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 Holdings is taking or proposes to take with respect thereto.


                                                                              46


            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 Holdings)
occurs and is continuing, the Senior Discount Notes Trustee by notice to
Holdings, or the Senior Discount Noteholders of at least 25% in principal amount
at maturity of the outstanding Senior Discount Notes by notice to Holdings, may
declare (a) the Accreted Value of all the Senior Discount Notes, if on or prior
to June 1, 2003, or (b) the principal of and accrued but unpaid interest on all
the Senior Discount Notes, if after June 1, 2003, to be due and payable. Upon
such a declaration, such Accreted Value or 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 Holdings occurs, (a) the Accreted Value of all the Senior
Discount Notes, if on or prior to June 1, 2003, or (b) the principal of and
interest on all the Senior Discount Notes, if after June 1, 2003, shall ipso
facto become and be immediately due and payable without any declaration or other
act on the part of the Senior Discount Notes Trustee or any Senior Discount
Noteholders. The Senior Discount Noteholders of a majority in principal amount
at maturity of the Senior Discount Notes by notice to the Senior Discount 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 nonpay ment of Accreted Value or 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 Discount Notes Trustee may pursue any available remedy to
collect the payment of Accreted Value or principal of or interest on the Senior
Discount Notes or to enforce the performance of any provision of the Senior
Discount Notes or this Indenture.

            The Senior Discount Notes Trustee may maintain a proceeding even if
it does not possess any of the Senior Discount Notes or does not produce any of
them in the proceeding. A delay or omission by the Senior Discount Notes Trustee
or any Senior Discount 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 at maturity of the Senior Discount Notes by notice to the
Senior Discount Notes Trustee may waive an existing Default and its consequences
except (i) a Default in the payment of Accreted Value or the principal of or
interest on a Senior Discount Note, (ii) a Default arising from the failure to
redeem or purchase any Senior Discount Note when 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 Discount
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 Discount Noteholders
of a majority in principal amount at maturity of the Senior Discount Notes may
direct the time, method and place of conducting any proceeding for any remedy
available to the Senior Discount Notes Trustee or of exercising any trust or
power conferred on the


                                                                              47


Senior Discount Notes Trustee. However, the Senior Discount Notes Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Senior Discount Notes Trustee determines is
unduly prejudicial to the rights of other Senior Discount Noteholders or would
involve the Senior Discount Notes Trustee in personal liability; provided,
however, that the Senior Discount Notes Trustee may take any other action deemed
proper by the Senior Discount Notes Trustee that is not inconsistent with such
direction. Prior to taking any action hereunder, the Senior Discount 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 Accreted Value, principal, premium (if any) or interest when
due, no Senior Discount Noteholder may pursue any remedy with respect to this
Indenture or the Senior Discount Notes unless:

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

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

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

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

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

            SECTION 6.07. Rights of Senior Discount Noteholders to Receive
Payment. Notwithstanding any other provision of this Indenture, the right of any
Senior Discount Noteholder to receive payment of Accreted Value, principal of
and liquidated damages and interest on the Senior Discount Notes held by such
Senior Discount Noteholder, on or after the respective due dates expressed in
the Senior Discount 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 Discount Noteholder.

            SECTION 6.08. Collection Suit by Senior Discount Notes Trustee. If
an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing, the Senior Discount Notes Trustee may recover judgment in its own
name and as trustee of an express trust against Holdings for the whole amount
then due and owing (together with


                                                                              48


interest on any unpaid interest to the extent lawful) and the amounts provided
for in Section 7.07.

            SECTION 6.09. Senior Discount Notes Trustee May File Proofs of
Claim. The Senior Discount 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 Discount Notes Trustee and the Senior Discount Noteholders allowed
in any judicial proceedings relative to Holdings, its creditors or its property
and, unless prohibited by law or applicable regulations, may vote on behalf of
the Senior Discount 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 Discount Noteholder to
make payments to the Senior Discount Notes Trustee and, in the event that the
Senior Discount Notes Trustee shall consent to the making of such payments
directly to the Senior Discount Noteholders, to pay to the Senior Discount Notes
Trustee any amount due it for the reasonable compensation, expenses, disburse
ments and advances of the Senior Discount Notes Trustee, its agents and its
counsel, and any other amounts due the Senior Discount Notes Trustee under
Section 7.07.

            SECTION 6.10. Priorities. If the Senior Discount Notes Trustee
collects 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 Discount Notes Trustee for amounts due under
      Section 7.07;

            SECOND: to Senior Discount Noteholders for amounts due and unpaid on
      the Senior Discount Notes for Accreted Value, 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 Discount
      Notes for Accreted Value, principal, any liquidated damages and interest,
      respectively; and

            THIRD: to Holdings.

            The Senior Discount Notes Trustee may fix a record date and payment
date for any payment to Senior Discount Noteholders pursuant to this Section. At
least 15 days before such record date, the Senior Discount Notes Trustee shall
mail to each Senior Discount Noteholder and Holdings 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
Discount Notes Trustee for any action taken or omitted by it as Senior Discount
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 Discount Notes Trustee, a
suit by a Senior Discount Noteholder pursuant to Section 6.07 or a suit by
Senior Discount Noteholders of more than 10% in principal amount at maturity of
the Senior Discount Notes.


                                                                              49


            SECTION 6.12. Waiver of Stay or Extension Laws. Holdings (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and 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 Discount Notes Trustee, but shall
suffer and permit the execution of every such power as though no such law had
been enacted.

                                    ARTICLE 7

                          Senior Discount Notes Trustee

            SECTION 7.01. Duties of Senior Discount Notes Trustee. (a) If an
Event of Default has occurred and is continuing, the Senior Discount 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 Discount 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
      Discount Notes Trustee; and

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

            (c) The Senior Discount 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:

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

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

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


                                                                              50


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

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

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

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

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

            SECTION 7.02. Rights of Senior Discount Notes Trustee. (a) The
Senior Discount Notes Trustee may rely on any document believed by it to be
genuine and to have been signed or presented by the proper person. The Senior
Discount Notes Trustee need not investigate any fact or matter stated in the
document.

            (b) Before the Senior Discount Notes Trustee acts or refrains from
acting, it may require an Officers' Certificate or an Opinion of Counsel. The
Senior Discount Notes Trustee shall not be liable for any action it takes or
omits to take in good faith in reliance on the Officers' Certificate or Opinion
of Counsel.

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

            (d) The Senior Discount Notes Trustee shall not be liable for any

authorized or within its rights or powers.

            (e) The Senior Discount Notes Trustee may consult with counsel, and
the advice or opinion of counsel with respect to legal matters relating to this
Indenture and the Senior Discount Notes shall be full and complete authorization
and protection from liability in respect to any action taken, omitted or
suffered by it hereunder in good faith and in accordance with the advice or
opinion of such counsel.

            (f) The Senior Discount Notes Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report, notice, request, consent, order,
approval, bond, debenture, note or other paper or document, but the Senior
Discount Notes Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit.


                                                                              51


            (g) The Senior Discount Notes Trustee shall be under no obligation
to exercise any of the rights or powers vested in it by this Indenture at the
request, order or direction of any of the Senior Discount Noteholders pursuant
to the provisions of this Indenture, unless such Senior Discount Noteholders
shall have offered to the Senior Discount Notes Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

            SECTION 7.03. Individual Rights of Senior Discount Notes Trustee.
The Senior Discount Notes Trustee in its individual or any other capacity may
become the owner or pledgee of Senior Discount Notes and may otherwise deal with
Holdings or its Affiliates with the same rights it would have if it were not
Senior Discount Notes Trustee. Any Paying Agent, Registrar or co-paying agent
may do the same with like rights. However, the Senior Discount Notes Trustee
must comply with Sections 7.10 and 7.11.

            SECTION 7.04. Senior Discount Notes Trustee's Disclaimer. The Senior
Discount Notes Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Senior Discount Notes,
it shall not be accountable for Holdings' use of the proceeds from the Senior
Discount Notes, and it shall not be responsible for any statement of Holdings in
this Indenture or in any document issued in connection with the sale of the
Senior Discount Notes or in the Senior Discount Notes other than the Senior
Discount Notes Trustee's certificate of authentication.

            SECTION 7.05. Notice of Defaults. (a) The Senior Discount Notes
Trustee shall not be deemed to have notice of any Default, other than a payment
default, unless a Trust Officer shall have been advised in writing that a
Default has occurred. No duty imposed upon the Senior Discount Notes Trustee in
this Indenture shall be applicable with respect to any Default of which the
Senior Discount Trustee is not deemed to have notice.

            (b) If a Default occurs and is continuing and if it is known to the
Senior Discount Notes Trustee, the Senior Discount Notes Trustee shall mail to
each Senior Discount Noteholder notice of the Default within the earlier of 90
days after it occurs or 30 days after it is known to a Trust Officer or written
notice of it is received by the Senior Discount Notes Trustee. Except in the
case of a Default in payment of Accreted Value, principal, premium (if any) or
interest on any Senior Discount Note (including payments pursuant to the
redemption provisions of such Senior Discount Note), the Senior Discount Notes
Trustee may withhold notice if and so long as a committee of its Trust Officers
in good faith determines that withholding notice is in the interests of the
Senior Discount Noteholders.

            SECTION 7.06. Reports by Senior Discount Notes Trustee to Senior
Discount 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 Discount
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 Discount Noteholder a brief report dated as of June 30 that complies
with Section 313(a) of the TIA. The Senior Discount Notes Trustee shall also
comply with Section 313(b) of the TIA.


                                                                              52


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

            SECTION 7.07. Compensation and Indemnity. Holdings shall pay to the
Senior Discount Notes Trustee from time to time such compensation as Holdings
and the Senior Discount Notes Trustee shall from time to time agree in writing.
The Senior Discount Notes Trustee's compensation shall not be limited by any law
on compensation of a trustee of an express trust. Holdings shall reimburse the
Senior Discount 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 Discount
Notes Trustee's agents, counsel, accountants and experts. Holdings shall
indemnify the Senior Discount 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 Discount
Notes or the administration of this trust and the performance of its duties
hereunder. The Senior Discount Notes Trustee shall notify Holdings of any claim
for which it may seek indemnity promptly upon obtaining actual knowledge
thereof; provided, however, that any failure so to notify Holdings shall not
relieve Holdings of its indemnity obligations hereunder. Holdings shall defend
the claim and the indemnified party shall provide reasonable cooperation at
Holdings' expense in the defense. Such indemnified parties may have separate
counsel and Holdings shall pay the fees and expenses of such counsel; provided,
however, that Holdings 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 Holdings and such
parties in connection with such defense. Holdings 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 Holdings' payment obligations in this Section, the Senior
Discount Notes Trustee shall have a lien prior to the Senior Discount Notes on
all money or property held or collected by the Senior Discount Notes Trustee
other than money or property held in trust to pay Accreted Value, principal of
and interest and any liquidated damages on particular Senior Discount Notes.

            Holdings' 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 Discount Notes Trustee. When the Senior Discount Notes Trustee incurs
expenses after the occurrence of a Default specified in Section 6.01(7) or (8)
with respect to Holdings, the expenses are intended to constitute expenses of
administration under the Bankruptcy Law.

            SECTION 7.08. Replacement of Senior Discount Notes Trustee. The
Senior Discount Notes Trustee may resign at any time by so notifying Holdings.
The Holders of a majority in principal amount at maturity of the Senior Discount
Notes may


                                                                              53


remove the Senior Discount Notes Trustee by so notifying the Senior Discount
Notes Trustee and may appoint a successor Senior Discount Notes Trustee.
Holdings shall remove the Senior Discount Notes Trustee if:

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

            (2) the Senior Discount Notes Trustee is adjudged bankrupt or
      insolvent;

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

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

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

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

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

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

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

            SECTION 7.09. Successor Senior Discount Notes Trustee by Merger. If
the Senior Discount Notes Trustee consolidates with, merges or converts into, or
transfers all or substantially all its corporate trust business or assets to,
another


                                                                              54


corporation or banking association, the resulting, surviving or transferee
corporation without any further act shall be the successor Senior Discount Notes
Trustee.

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

            SECTION 7.10. Eligibility; Disqualification. The Senior Discount
Notes Trustee shall at all times satisfy the requirements of TIA ss. 310(a). The
Senior Discount 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 Discount 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 Holdings are
out standing if the requirements for such exclusion set forth in TIA ss.
310(b)(1) are met.

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

                                    ARTICLE 8

                       Discharge of Indenture; Defeasance

            SECTION 8.01. Discharge of Liability on Senior Discount Notes;
Defeasance. (a) When (i) Holdings delivers to the Senior Discount Notes Trustee
all outstanding Senior Discount Notes (other than Senior Discount Notes replaced
pursuant to Section 2.07) for cancelation or (ii) all outstanding Senior
Discount 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
Holdings irrevocably deposits with the Senior Discount 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
Discount Notes, including interest thereon to maturity or such redemption date
(other than Senior Discount Notes replaced pursuant to Section 2.07), and if in
either case Holdings pays all other sums payable hereunder by Holdings, then
this Indenture shall, subject to Section 8.01(c), cease to be of further effect.
The Senior Discount Notes Trustee shall acknowledge satisfaction and discharge
of this Indenture on demand of Holdings accompanied by an Officers' Certificate
and an Opinion of Counsel and at the cost and expense of Holdings.


                                                                              55


            (b) Subject to Sections 8.01(c) and 8.02, Holdings at any time may
terminate (i) all of its obligations under the Senior Discount 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 Holdings only), 6.01(8) (with respect to
Significant Subsidiaries of Holdings only) and 6.01(9) ("covenant defeasance
option"). Holdings may exercise its legal defeasance option not withstanding its
prior exercise of its covenant defeasance option.

            If Holdings exercises its legal defeasance option, payment of the
Senior Discount Notes may not be accelerated because of an Event of Default. If
Holdings exer cises its covenant defeasance option, payment of the Senior
Discount 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 Holdings only) or 6.01(8) (with respect to Significant Subsidiaries of
Holdings only) or because of the failure of Holdings to comply with clauses
(iii) and (iv) of Section 5.01.

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

            (c) Notwithstanding clauses (a) and (b) above, Holdings' obligations
in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07, 7.08 and in this Article 8
shall survive until the Senior Discount Notes have been paid in full.
Thereafter, Holdings' obligations in Sections 7.07, 8.04 and 8.05 shall survive.

      principal, premium (if any) and interest on the Senior Discount Notes to
      maturity or redemption, as the case may be;

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

            (3) 123 days pass after the deposit is made and during the 123-day

      agreement binding on Holdings;

            (5) Holdings delivers to the Senior Discount Notes Trustee an
      Opinion of Counsel to the effect that the trust resulting from the deposit
      does not constitute,

      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 Discount 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, Holdings shall
      have delivered to the Senior Discount Notes Trustee an Opinion of Counsel
      to the effect that the Senior Discount 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

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,

under this Indenture and the Senior Discount Notes shall be revived and
reinstated as though no deposit had occurred pursuant to this Article 8 until
such time as the Senior Discount 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 Holdings has made any payment of interest
on or principal of any Senior Discount Notes because of the reinstatement of its
obligations, Holdings shall be subrogated to the rights of the Senior Discount
Noteholders of such Senior Discount Notes to receive such payment from the money
or U.S. Government Obligations held by the Senior Discount Notes Trustee or
Paying Agent.

                                    ARTICLE 9

                                   Amendments

            SECTION 9.01. Without Consent of Senior Discount Noteholders.
Holdings and the Senior Discount Notes Trustee may amend this Indenture or the
Senior Discount Notes without notice to or consent of any Senior Discount
Noteholder:

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

            (2) to comply with Article 5;

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

            (4) to add Guarantees with respect to the Senior Discount Notes or
      to secure the Senior Discount Notes;

            (5) to add to the covenants of Holdings for the benefit of the
      Senior Discount Noteholders or to surrender any right or power herein
      conferred upon Holdings;

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

            (7) to make any change that does not adversely affect the rights of
      any Senior Discount Noteholder; or


                                                                              58


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

            After an amendment under this Section becomes effective, Holdings
shall mail to Senior Discount Noteholders a notice briefly describing such
amendment. The failure to give such notice to all Senior Discount 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 Discount Noteholders. Holdings
and the Senior Discount Notes Trustee may amend this Indenture or the Senior
Discount Notes with the written consent of the Holders of at least a majority in
principal amount at maturity of the Senior Discount Notes then outstanding
(including consents obtained in connection with a tender offer or exchange offer
for the Senior Discount Notes), without notice to any other Senior Discount
Noteholder. However, without the consent of each Holder of an outstanding Senior
Discount Note affected, an amendment may not:

            (1) reduce the principal amount of Senior Discount Notes whose
      Senior Discount 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 Discount Note;

            (3) reduce the Accreted Value or principal of or extend the Stated

      redeemed in accordance with Article 3;

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

            (6) 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 Discount
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.

            After an amendment under this Section becomes effective, Holdings
shall mail to Senior Discount Noteholders a notice briefly describing such
amendment. The failure to give such notice to all Senior Discount 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 Discount Notes shall comply with the TIA as then
in effect.


                                                                              59


            SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Senior Discount Noteholder of a Senior
Discount Note shall bind the Senior Discount Noteholder and every subsequent
Senior Discount Noteholder of that Senior Discount Note or portion of the Senior
Discount Note that evidences the same debt as the consenting Senior Discount
Noteholder's Senior Discount Note, even if notation of the consent or waiver is
not made on the Senior Discount Note. However, any such Senior Discount
Noteholder or subsequent Senior Discount Noteholder may revoke the consent or
waiver as to such Senior Discount Noteholder's Senior Discount Note or portion
of the Senior Discount Note if the Senior Discount 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
Discount Noteholder. An amendment or waiver becomes effective once both (i) the
requisite number of consents have been received by Holdings or the Senior
Discount Notes Trustee and (ii) such amendment or waiver has been executed by
Holdings and the Senior Discount Notes Trustee.

            Holdings may, but shall not be obligated to, fix a record date for
the purpose of determining the Senior Discount 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 Discount 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 Discount 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 Discount Notes. If
an amendment changes the terms of a Senior Discount Note, the Senior Discount
Notes Trustee may require the Senior Discount Noteholder of the Senior Discount
Note to deliver it to the Senior Discount Notes Trustee. The Senior Discount
Notes Trustee may place an appropriate notation on the Senior Discount Note
regarding the changed terms and return it to the Senior Discount Noteholder.
Alternatively, if Holdings or the Senior Discount Notes Trustee so determines,
Holdings in exchange for the Senior Discount Note shall issue and the Senior
Discount Notes Trustee shall authenticate a new Senior Discount Note that
reflects the changed terms. Failure to make the appropriate notation or to issue
a new Senior Discount Note shall not affect the validity of such amendment.

            SECTION 9.06. Senior Discount Notes Trustee To Sign Amendments. The
Senior Discount 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 Discount Notes Trustee. If it does, the
Senior Discount Notes Trustee may but need not sign it. In signing such
amendment the Senior Discount 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 Holdings enforceable against it in accordance with its terms,
subject to customary exceptions, and complies with the provisions hereof
(including Section 9.03).


                                                                              60

outstanding, except that, for the purpose of determining whether the Senior
Discount Notes Trustee shall be protected in relying on any such direction,

            (i) certification (in the form set forth on the reverse side of the
      Initial Senior Discount Note) that such Definitive Senior Discount Note is

participant account of the Depositary to be credited with a beneficial interest
in such Global Senior Discount Note or another Global Senior Discount Note and
such account shall be credited in accordance with such order with a beneficial
interest in the applicable Global Senior Discount Note and the account of the
Person making the transfer shall be debited by an amount equal to the beneficial
interest in the Global Senior Discount Note being transferred. Transfers by an
owner of a beneficial interest in the Rule 144A Global Senior Discount Note or
the IAI Global Senior Discount Note to a transferee who takes delivery of such
interest through the Regulation S Global Senior Discount Note, whether before or
after the expiration of the Restricted Period, will be made only upon receipt by
the Senior Discount Notes Trustee of a certification from the transferor to the
effect that such transfer is being made in accordance with Regulation S or (if

will be held immediately thereafter through Euroclear or Cedel. In the case of a

Discount Note or the Rule 144A Global Senior Discount Note for an interest in
the IAI Global Senior Discount Note, the transferee must furnish a signed letter
substantially in the form of Exhibit D to the Senior Discount Notes Trustee.

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

                                                                               7

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

            (iv) In the event that a Global Senior Discount Note is exchanged
      for Definitive Senior Discount Notes pursuant to Section 2.4 prior to the
      consummation of the Senior Discount Notes Registered Exchange Offer or the
      effectiveness of the Senior Discount Notes Shelf Registration Statement
      with respect to such Senior Discount Notes, such Senior Discount 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
      Discount Notes intended to ensure that such transfers comply with Rule
      144A, Regulation S or such other applicable exemption from registration
      under the Securities Act, as the case may be) and such other procedures as
      may from time to time be adopted by Holdings.

            (d) Restrictions on Transfer of Regulation S Global Senior Discount
Note. (i) Prior to the expiration of the Restricted Period, interests in the
Regulation S Global Senior Discount Note may only be held through Euroclear or
Cedel. During the Restricted Period, beneficial ownership interests in the

Global Senior Discount Note for an interest in the IAI Global Senior Discount
Note, the transferee must furnish a signed letter substantially in the form of
Exhibit D to the Senior Discount Notes Trustee.

                                                                               8

with respect to such Global Senior Discount Note, by the Senior Discount Notes
Trustee or the Senior Discount Notes Custodian, to reflect such reduction.

      payable in connection therewith (other than any such transfer taxes,
      assessments or similar governmental charge payable upon exchange or
      transfer pursuant to Section 3.06, 4.06, 4.08 and 9.05).

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

            (iv) All Senior Discount Notes issued upon any transfer or exchange
      pursuant to the terms of this Indenture shall evidence the same debt and
      shall be entitled to the

                                       11

            (i) The Senior Discount Notes Trustee shall have no responsibility
      or obligation to any beneficial owner of a Global Senior Discount Note, a
      member of, or a participant in the Depositary or any other Person with
      respect to the accuracy of the records of the Depositary or its nominee or
      of any participant or member thereof, with respect to any ownership
      interest in the Senior Discount Notes or with respect to the delivery to
      any participant, member, beneficial owner or other Person (other than the
      Depositary) of any notice (including any notice of redemption or
      repurchase) or the payment of any amount, under or with respect to such
      Senior Discount Notes. All notices and communications to be given to the
      Senior Discount Noteholders and all payments to be made to Senior Discount
      Noteholders under the Senior Discount Notes shall be given or made only to
      the registered Senior Discount Noteholders (which shall be the Depositary
      or its nominee in the case of a Global Senior Discount Note). The rights
      of beneficial owners in any Global Senior Discount Note shall be exercised
      only through the Depositary subject to the applicable rules and procedures
      of the Depositary. The Senior Discount Notes Trustee may rely and shall be
      fully protected in relying upon information furnished by the Depositary
      with respect to its members, participants and any beneficial owners.

            (ii) The Senior Discount Notes Trustee shall have no obligation or
      duty to monitor, determine or inquire as to compliance with any
      restrictions on transfer imposed under this Indenture or under applicable
      law with respect to any transfer of any interest in any Senior Discount
      Note (including any transfers between or among Depositary participants,

      evidence as are expressly required by, and to do so if and when expressly

                      11 1/8% Senior Discount Note due 2008

1. Interest

            (a) WESCO INTERNATIONAL, INC., a Delaware corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called "Holdings"), promises to pay interest on the
principal amount at maturity of this Senior Discount Note at the rate per annum
shown above. Cash interest will not accrue or be payable on this Senior Discount
Note prior to June 1, 2003. From June 1, 2003, Holdings will pay interest
semiannually on June 1 and December 1 of each year. Interest on the Senior
Discount Notes will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from June 1, 2003. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

            (b) Liquidated Damages. The holder of this Senior Discount Note is
entitled to the benefits of an Exchange and Registration Rights Agreement, dated
as of June 5, 1998, among Holdings and the Initial Purchasers named therein (the
"Senior Discount Notes Registration Agreement"). Capitalized terms used in this
paragraph (b) but not defined herein have the meanings assigned to them in the
Senior Discount Notes Registration Agreement. If (i) the Senior Discount Notes
Shelf Registration Statement or Senior Discount Notes Exchange Offer
Registration Statement, as applicable under the Senior Discount Notes
Registration Agreement, is not filed with the Commission on or prior to 90 days
after the Senior Discount Notes Issue Date (or, in the case of a Senior Discount
Notes Shelf Registration Statement required to be filed in response to a change
in law or applicable interpretations of the Commission's staff, if later, within
45 days after publication of the change in law or interpretations, but in no
event before 90 days after the Senior Discount Notes Issue Date), (ii) the
Senior Discount Notes Exchange Offer Registration Statement or the Senior
Discount Notes Shelf Registration Statement, as the case may be, is not declared
effective within 200 days after the Senior Discount Notes Issue Date (or in the
case of a Senior Discount Notes Shelf Registration Statement required to be
filed in response to a change in law or the applicable 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 Discount
Notes Issue Date), (iii) the Senior Discount Notes Registered Exchange Offer is
not consummated on or prior to 230 days after the Senior Discount Notes Issue
Date (other than in the event Holdings files a Senior Discount Notes Shelf
Registration Statement), or (iv) the Senior Discount Notes Shelf Registration
Statement is filed and declared effective within 200 days after the Senior
Discount Notes Issue Date but shall thereafter cease to be effective (at any
time that Holdings is obligated to maintain the effectiveness thereof) without
being succeeded within 90 days by an additional Senior Discount Notes
Registration Statement filed and declared effective (each such event referred to
in clauses (i) through (iv), a "Registration Default"), Holdings shall pay
liquidated damages to each holder of Transfer Restricted Senior Discount Notes,
during the period of such Registration Default, in an amount equal to $0.192 per
week per $1,000 Accreted Value of the Senior Discount Notes constituting
Transfer Restricted Senior Discount Notes held by such holder until (i) the
applicable Senior Discount Notes Registration Statement is filed, (ii) the
Senior Discount Notes Exchange Offer Registration Statement is declared
effective and the Senior Discount Notes Registered Exchange Offer is
consummated, (iii) the Senior Discount Notes Shelf Registration Statement is
declared effective or (iv) the Senior Discount

                                                                               2


Notes Shelf Registration Statement again becomes effective, as the case may be.
All accrued liquidated damages shall be paid to holders on the next semi-annual
accretion date (if on or prior to June 1, 2003) or in the same manner as
interest payments on the Senior Discount Notes on semi-annual payment dates
which correspond to interest payment dates for the Senior Discount Notes (if
after June 1, 2003). Following the cure of all Registration Defaults, the
accrual of liquidated damages will cease. The Senior Discount 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 Discount Notes" means (i) each Initial Senior Discount Note until the
date on which such Initial Senior Discount Note has been exchanged for a freely
transferable Senior Discount Exchange Note in the Senior Discount Notes
Registered Exchange Offer, (ii) each Initial Senior Discount Note or Private
Senior Discount Exchange Note until the date on which such Initial Senior
Discount Note or Private Senior Discount Exchange Note has been effectively
registered under the Securities Act and disposed of in accordance with a Senior
Discount Notes Shelf Registration Statement or (iii) each Initial Senior
Discount Note or Private Senior Discount Exchange Note until the date on which
such Initial Senior Discount Note or Private Senior Discount 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

            Holdings will pay interest on the Senior Discount Notes (except
defaulted interest) to the Persons who are registered holders of Senior Discount
Notes at the close of business on the May 15 or November 15 next preceding the
interest payment date even if Senior Discount Notes are canceled after the
record date and on or before the interest payment date. Holders must surrender
Senior Discount Notes to a Paying Agent to collect principal payments. Holdings
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 Discount Notes represented by a Global Senior
Discount 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. Holdings will make all payments in respect of a
certificated Senior Discount Note (including principal, premium and interest),
by mailing a check to the registered address of each Senior Discount Noteholder
thereof; provided, however, that payments on the Senior Discount Notes may also
be made, in the case of a Senior Discount Noteholder of at least $1,000,000
aggregate principal amount at maturity of Senior Discount Notes, by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Senior Discount Noteholder elects payment by wire transfer
by giving written notice to the Senior Discount 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
Discount Notes Trustee may accept in its discretion).

3. Paying Agent and Registrar

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

                                                                               3

4. Indenture

            Holdings issued the Senior Discount Notes under an Indenture dated
as of June 5, 1998 (the "Indenture"), among Holdings and the Senior Discount
Notes Trustee. The terms of the Senior Discount 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 Discount
Notes are subject to all such terms, and Senior Discount Noteholders are
referred to the Indenture and the TIA for a statement of those terms.

            The Senior Discount Notes are senior unsecured obligations of
Holdings limited to $87 million aggregate principal amount at maturity at any
one time outstanding (subject to Section 2.07 of the Indenture). This Senior
Discount Note is one of the Initial Senior Discount Notes referred to in the
Indenture issued in an aggregate principal amount at maturity of $87 million.
The Senior Discount Notes include the Initial Senior Discount Notes and any
Senior Discount Exchange Notes issued in exchange for Initial Senior Discount
Notes. The Initial Senior Discount Notes and the Senior Discount Exchange Notes
are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of Holdings 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 Holdings to consolidate or merge with or
into any other Person or convey, transfer or lease all or substantially all of
the property of Holdings.

Discount Noteholder of Senior Discount Notes to be redeemed at his or her
registered address. Senior Discount Notes in denominations larger than $1,000
(in principal amount at maturity) 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 Discount 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 Discount Notes (or such
portions thereof) called for redemption.

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

            Upon a Change of Control, any Senior Discount Noteholder of Senior
Discount Notes will have the right, subject to certain conditions specified in
the Indenture, to cause Holdings to repurchase all or any part of the Senior
Discount Notes of such Senior Discount Noteholder at a purchase price equal to
(a) 101% of the Accreted Value thereof at the date of repurchase plus liquidated
damages thereon, if any, to the date of repurchase, if repurchased on or prior
to June 1, 2003, and (b) 101% of the principal amount of the Senior Discount
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 Discount
Noteholders of record on the relevant record date to receive interest due on the
relevant interest payment date), if repurchased after June 1, 2003, as provided
in, and subject to the terms of, the Indenture.

9. Mandatory Principal Redemption

            On June 1, 2003, Holdings will be required to redeem an amount equal
to $354.96 per $1,000 principal amount at maturity of each Senior Discount Note
then outstanding ($30,881,520 in aggregate principal amount at maturity of the
Senior Discount Notes, assuming all of the Senior Discount Notes remain
outstanding on such date (the "Mandatory Principal Redemption Amount")) on a pro
rata basis at a redemption price of 100% of the principal amount at maturity of
the Senior Discount Notes so redeemed. If the redemption of a Senior Discount
Note pursuant to this paragraph 9 would result in an outstanding Senior Discount
Note in a denomination (i) of less than $1,000 principal amount

                                                                               5


at maturity or (ii) other than an integral multiple of $1,000 principal amount
at maturity, such Senior Discount Note will be redeemed (A) in whole, in the
case of clause (i), or (B) by an additional amount so that such Senior Discount
Note will be in a denomination of an integral multiple of $1,000 principal
amount at maturity, in the case of clause (ii).

10. Denominations; Transfer; Exchange

            The Senior Discount Notes are in registered form without coupons in
denominations of $1,000 (in principal amount at maturity) and whole multiples of
$1,000. A Senior Discount Noteholder may transfer or exchange Senior Discount
Notes in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Senior Discount Notes Trustee may require a Senior Discount
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 Discount
Notes selected for redemption (except, in the case of a Senior Discount Note to
be redeemed in part, the portion of the Senior Discount Note not to be redeemed)
or to transfer or exchange any Senior Discount Notes for a period of 15 days
prior to a selection of Senior Discount Notes to be redeemed.

11. Persons Deemed Owners

            The registered Senior Discount Noteholder of this Senior Discount
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 Discount Notes Trustee or Paying Agent shall pay the
money back to Holdings at its written request unless an abandoned property law
designates another Person. After any such payment, Senior Discount Noteholders
entitled to the money must look only to Holdings and not to the Senior Discount
Notes Trustee for payment.

13. Discharge and Defeasance

            Subject to certain conditions, Holdings at any time may terminate
some of or all its obligations under the Senior Discount Notes and the Indenture
if Holdings deposits with the Senior Discount Notes Trustee money or U.S.
Government Obligations for the payment of principal and interest on the Senior
Discount 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 Discount Notes may be amended without prior notice to
any Senior Discount Noteholder but with the written consent of the Senior
Discount Noteholders of at least a majority in aggregate principal amount at
maturity of the outstanding Senior Discount Notes and (ii) any default or
noncompliance with any provision may be waived with the written consent of the
Senior Discount Noteholders of at least a majority in principal amount at
maturity of the outstanding Senior Discount Notes. Subject to certain exceptions
set forth in the Indenture, without the consent of any Senior Discount
Noteholder of Senior Discount Notes, Holdings and the Senior Discount Notes
Trustee may amend the Indenture or the

                                                                               6


Senior Discount 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 Discount Notes in addition to or in place of
certificated Senior Discount Notes; (iv) to add Guarantees with respect to the
Senior Discount Notes; (v) to secure the Senior Discount Notes; (vi) to add
additional covenants of Holdings for the benefit of the Senior Discount
Noteholders or to surrender rights and powers conferred on Holdings; (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 Discount Noteholder; or (ix)
to provide for the issuance of the Senior Discount Exchange Notes or Private
Senior Discount Exchange 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
Holdings) and is continuing, the Senior Discount Notes Trustee or the Senior
Discount Noteholders of at least 25% in principal amount at maturity of the
outstanding Senior Discount Notes may declare (a) the Accreted Value of all the
Senior Discount Notes, if on or prior to June 1, 2003, or (b) the principal of
and accrued but unpaid interest on all the Senior Discount Notes, if after June
1, 2003, to be due and payable. If an Event of Default relating to certain
events of bankruptcy, insolvency or reorganization of Holdings occurs, (a) the
Accreted Value of all the Senior Discount Notes, if on or prior to June 1, 2003,
or (b) the principal of and interest on all the Senior Discount Notes, if after
June 1, 2003, will become immediately due and payable without any declaration or
other act on the part of the Senior Discount Notes Trustee or any Senior
Discount Noteholders. Under certain circumstances, the Senior Discount
Noteholders of a majority in principal amount at maturity of the outstanding
Senior Discount Notes may rescind any such acceleration with respect to the
Senior Discount Notes and its consequences.

            If an Event of Default occurs and is continuing, the Senior Discount
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
Discount Noteholders unless such Senior Discount Noteholders have offered to the
Senior Discount Notes Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of Accreted
Value, principal, premium (if any) or interest when due, no Senior Discount
Noteholder may pursue any remedy with respect to the Indenture or the Senior
Discount Notes unless (i) such Senior Discount Noteholder has previously given
the Senior Discount Notes Trustee notice that an Event of Default is continuing,
(ii) Senior Discount Noteholders of at least 25% in principal amount at maturity
of the outstanding Senior Discount Notes have requested the Senior Discount
Notes Trustee in writing to pursue the remedy, (iii) such Senior Discount
Noteholders have offered the Senior Discount Notes Trustee reasonable security
or indemnity against any loss, liability or expense, (iv) the Senior Discount
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
Discount Noteholders of a majority in principal amount at maturity of the
outstanding Senior Discount Notes have not given the Senior Discount Notes
Trustee a direction inconsistent with such request within such 60-day period.
Subject to certain restrictions, the Senior Discount Noteholders of a majority
in principal amount at maturity of the outstanding Senior Discount Notes are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Senior Discount Notes Trustee or of
exercising any trust or power conferred on the Senior Discount Notes Trustee.
The Senior Discount Notes Trustee, however, may

                                                                               7


refuse to follow any direction that conflicts with law or the Indenture or that
the Senior Discount Notes Trustee determines is unduly prejudicial to the rights
of any other Senior Discount Noteholder or that would involve the Senior
Discount Notes Trustee in personal liability. Prior to taking any action under
the Indenture, the Senior Discount 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 Discount Notes Trustee Dealings with Holdings

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

17. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of Holdings
shall not have any liability for any obligations of Holdings under the Senior
Discount 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 Discount
Note, each Senior Discount Noteholder waives and releases all such liability.
The waiver and release are part of the consideration for the issue of the Senior
Discount Notes.

18. Authentication

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

19. Abbreviations

            Customary abbreviations may be used in the name of a Senior Discount
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 DISCOUNT 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, Holdings has caused CUSIP numbers to be
printed on the Senior Discount Notes and has directed the Senior Discount Notes
Trustee to use CUSIP numbers in notices of redemption as a convenience to Senior
Discount Noteholders. No

the Senior Discount Notes or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

Discount Notes upon written request and without charge to the Senior Discount
Noteholder a copy of the Indenture which has in it the text of this Senior

            WESCO INTERNATIONAL, INC., a Delaware corporation (such corporation,
and its successors and assigns under the Indenture hereinafter referred to,
being herein called "Holdings"), promises to pay interest on the principal
amount at maturity of this Senior Discount Note at the rate per annum shown
above. Cash interest will not accrue or be payable on this Senior Discount Note
prior to June 1, 2003. From June 1, 2003, Holdings will pay interest
semiannually on June 1 and December 1 of each year. Interest on the Senior

paid or, if no interest has been paid, from June 1, 2003. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

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 Discount Notes Trustee may accept in its
discretion).

3. Paying Agent and Registrar

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

                                                                               2


4. Indenture

            Holdings issued the Senior Discount Notes under an Indenture dated
as of June 5, 1998 (the "Indenture"), among Holdings and the Senior Discount
Notes Trustee. The terms of the Senior Discount 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 Discount
Notes are subject to all such terms, and Senior Discount Noteholders are
referred to the Indenture and the TIA for a statement of those terms.

            The Senior Discount Notes are senior unsecured obligations of
Holdings limited to $87 million aggregate principal amount at maturity at any
one time outstanding. This Senior Discount Note is one of the Initial Senior
Discount Notes referred to in the Indenture. The Senior Discount Notes include
the Initial Senior Discount Notes and any Senior Discount Exchange Notes and
Private Senior Discount Exchange Notes issued in exchange for the Initial Senior
Discount Notes pursuant to the Indenture. The Initial Senior Discount Notes, the
Senior Discount Exchange Notes and the Private Senior Discount Exchange Notes
are treated as a single class of securities under the Indenture. The Indenture
imposes certain limitations on the ability of Holdings 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 Holdings to consolidate or merge with or
into any other Person or convey, transfer or lease all or substantially all of
the property of Holdings.

5. Optional Redemption

            Except as set forth in the following two paragraphs, the Senior
Discount Notes will not be redeemable at the option of Holdings prior to June 1,
2003. Thereafter, the Senior Discount Notes will be redeemable at the option of
Holdings, 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 at maturity), plus accrued and unpaid interest and liquidated
damages (if any) to the redemption date (subject to the right of holders of

                                                                  Redemption
     Year                                                            Price

            In addition, at any time prior to June 1, 2001, Holdings may redeem,
in whole but not in part, the Senior Discount Notes with the Net Cash Proceeds
of one or more Equity Offerings by Holdings, at a redemption price equal to
111.125% of the Accreted Value at the

date of redemption plus liquidated damages, if any, thereon to the date of
redemption. 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 Discount 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 Discount Notes may be
redeemed, in whole but not in part, at the option of Holdings at any time within
180 days after a Change of Control, at a redemption price equal to the sum of
(i) 100% of the Accreted Value thereof together with liquidated damages, if any,
to the redemption date plus (ii) the Applicable Premium.

6. Sinking Fund

            The Senior Discount 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
Discount Noteholder of Senior Discount Notes to be redeemed at his or her
registered address. Senior Discount Notes in denominations larger than $1,000
(in principal amount at maturity) 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 Discount 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 Discount Notes (or such
portions thereof) called for redemption.

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

            Upon a Change of Control, any Senior Discount Noteholder of Senior
Discount Notes will have the right, subject to certain conditions specified in
the Indenture, to cause Holdings to repurchase all or any part of the Senior
Discount Notes of such Senior Discount Noteholder at a purchase price equal to
(a) 101% of the Accreted Value thereof at the date of repurchase plus liquidated
damages thereon, if any, to the date of repurchase, if repurchased on or prior
to June 1, 2003, and (b) 101% of the principal amount of the Senior Discount
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 Discount
Noteholders of record on the relevant record date to receive interest due on the
relevant interest payment date), if repurchased after June 1, 2003, as provided
in, and subject to the terms of, the Indenture.

9. Mandatory Principal Redemption

            On June 1 , 2003, Holdings will be required to redeem an amount
equal to $354.96 per $1,000 principal amount at maturity of each Senior Discount
Note then outstanding ($30,881,520 in aggregate principal amount at maturity of
the Senior Discount Notes, assuming all of the Senior Discount Notes remain
outstanding on such date (the "Mandatory Principal Redemption Amount")) on a pro
rata basis at a redemption price of 100% of the principal amount at maturity of
the Senior Discount Notes so redeemed. If the redemption of a Senior Discount
Note pursuant to this paragraph 9 would result in an outstanding Senior Discount
Note in a denomination (i) of less than $1,000 principal amount

                                                                               4


at maturity or (ii) other than an integral multiple of $1,000 principal amount
at maturity, such Senior Discount Note will be redeemed (A) in whole, in the
case of clause (i), or (B) by an additional amount so that such Senior Discount
Note will be in a denomination of an integral multiple of $1,000 principal
amount at maturity, in the case of clause (ii).

10. Denominations; Transfer; Exchange

            The Senior Discount Notes are in registered form without coupons in
denominations of $1,000 (in principal amount and maturity) and whole multiples
of $1,000. A Senior Discount Noteholder may transfer or exchange Senior Discount
Notes in accordance with the Indenture. Upon any transfer or exchange, the
Registrar and the Senior Discount Notes Trustee may require a Senior Discount
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 Discount
Notes selected for redemption (except, in the case of a Senior Discount Note to
be redeemed in part, the portion of the Senior Discount Note not to be redeemed)
or to transfer or exchange any Senior Discount Notes for a period of 15 days
prior to a selection of Senior Discount Notes to be redeemed or 15 days before
an interest payment date.

11. Persons Deemed Owners

            The registered Senior Discount Noteholder of this Senior Discount
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 Discount Notes Trustee or Paying Agent shall pay the
money back to Holdings at its written request unless an abandoned property law
designates another Person. After any such payment, Senior Discount Noteholders
entitled to the money must look only to Holdings and not to the Senior Discount
Notes Trustee for payment.

13. Discharge and Defeasance

            Subject to certain conditions, Holdings at any time may terminate
some of or all its obligations under the Senior Discount Notes and the Indenture
if Holdings deposits with the Senior Discount Notes Trustee money or U.S.
Government Obligations for the payment of principal and interest on the Senior
Discount 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 Discount Notes may be amended without prior notice to
any Senior Discount Noteholder but with the written consent of the Senior
Discount Noteholders of at least a majority in aggregate principal amount at
maturity of the outstanding Senior Discount Notes and (ii) any default or
noncompliance with any provision may be waived with the written consent of the
Senior Discount Noteholders of at least a majority in principal amount at
maturity of the outstanding Senior Discount Notes. Subject to certain exceptions
set forth in the Indenture, without the consent of any Senior Discount
Noteholder of Senior Discount Notes, Holdings and the Senior Discount Notes
Trustee may amend the Indenture or the

                                                                               5


Senior Discount 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 Discount Notes in addition to or in place of
certificated Senior Discount Notes; (iv) to add Guarantees with respect to the
Senior Discount Notes; (v) to secure the Senior Discount Notes; (vi) to add
additional covenants of Holdings for the benefit of the Senior Discount
Noteholders or to surrender rights and powers conferred on Holdings; (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 Discount Noteholder; or (ix)
to provide for the issuance of the Senior Discount Exchange Notes or Private
Senior Discount Exchange 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
Holdings) and is continuing, the Senior Discount Notes Trustee or the Senior
Discount Noteholders of at least 25% in principal amount at maturity of the
outstanding Senior Discount Notes may declare (a) the Accreted Value of all the
Senior Discount Notes, if on or prior to June 1, 2003, or (b) the principal of
and accrued but unpaid interest on all the Senior Discount Notes, if after June
1, 2003, to be due and payable. If an Event of Default relating to certain
events of bankruptcy, insolvency or reorganization of Holdings occurs, (a) the
Accreted Value of all the Senior Discount Notes, if on or prior to June 1, 2003,
or (b) the principal of and interest on all the Senior Discount Notes, if after
June 1, 2003, will become immediately due and payable without any declaration or
other act on the part of the Senior Discount Notes Trustee or any Senior
Discount Noteholders. Under certain circumstances, the Senior Discount
Noteholders of a majority in principal amount at maturity of the outstanding
Senior Discount Notes may rescind any such acceleration with respect to the
Senior Discount Notes and its consequences.

            If an Event of Default occurs and is continuing, the Senior Discount
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
Discount Noteholders unless such Senior Discount Noteholders have offered to the
Senior Discount Notes Trustee reasonable indemnity or security against any loss,
liability or expense. Except to enforce the right to receive payment of Accreted
Value, principal, premium (if any) or interest when due, no Senior Discount
Noteholder may pursue any remedy with respect to the Indenture or the Senior
Discount Notes unless (i) such Senior Discount Noteholder has previously given
the Senior Discount Notes Trustee notice that an Event of Default is continuing,
(ii) Senior Discount Noteholders of at least 25% in principal amount at maturity
of the outstanding Senior Discount Notes have requested the Senior Discount
Notes Trustee in writing to pursue the remedy, (iii) such Senior Discount
Noteholders have offered the Senior Discount Notes Trustee reasonable security
or indemnity against any loss, liability or expense, (iv) the Senior Discount
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
Discount Noteholders of a majority in principal amount at maturity of the
outstanding Senior Discount Notes have not given the Senior Discount Notes
Trustee a direction inconsistent with such request within such 60-day period.
Subject to certain restrictions, the Senior Discount Noteholders of a majority
in principal amount at maturity of the outstanding Senior Discount Notes are
given the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Senior Discount Notes Trustee or of
exercising any trust or power conferred on the Senior Discount Notes Trustee.
The Senior Discount Notes Trustee, however, may

                                                                               6


refuse to follow any direction that conflicts with law or the Indenture or that
the Senior Discount Notes Trustee determines is unduly prejudicial to the rights
of any other Senior Discount Noteholder or that would involve the Senior
Discount Notes Trustee in personal liability. Prior to taking any action under
the Indenture, the Senior Discount 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 Discount Notes Trustee Dealings with Holdings

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

17. No Recourse Against Others

            A director, officer, employee or stockholder, as such, of Holdings
shall not have any liability for any obligations of Holdings under the Senior
Discount 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 Discount
Note, each Senior Discount Noteholder waives and releases all such liability.
The waiver and release are part of the consideration for the issue of the Senior
Discount Notes.

18. Authentication

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

19. Abbreviations

            Customary abbreviations may be used in the name of a Senior Discount
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 DISCOUNT 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, Holdings has caused CUSIP numbers to be
printed on the Senior Discount Notes and has directed the Senior Discount Notes
Trustee to use CUSIP numbers in notices of redemption as a convenience to Senior
Discount Noteholders. No

                                                                               7

the Senior Discount Notes or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon.

            Holdings will furnish to any Senior Discount Noteholder of Senior
Discount Notes upon written request and without charge to the Senior Discount
Noteholder a copy of the Indenture which has in it the text of this Senior

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 at
maturity of the Senior Discount Notes, and we are acquiring the Senior Discount
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 Discount Notes, and we invest
in or purchase Senior Discount Notes similar to the Senior Discount 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 Discount 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 Discount Notes
to offer, sell or otherwise transfer such Senior Discount Notes prior to the
date that is two years after the later of the date of original issue and the
last date on which Holdings or any affiliate of Holdings was the owner of such


                                                                               2


Senior Discount Notes (or any predecessor thereto) (the "Resale Restriction
Termination Date") only (a) to Holdings, (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 at maturity 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 Holdings and the Senior Discount
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
Discount Notes for investment purposes and not for distribution in violation of
the Securities Act. Each purchaser acknowledges that Holdings and the Senior
Discount Notes Trustee reserve the right prior to the offer, sale or other
transfer prior to the Resale Termination Date of the Senior Discount Notes
pursuant to clause (d), (e) or (f) above to require the delivery of an opinion
of counsel, certifications or other information satisfactory to Holdings and the
Senior Discount Notes Trustee.
