          TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND
          AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THIS NOTE (THE
          FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE), AND, IF SUCH
          TRANSFER IS IN RESPECT OF AN AGGREGATE PRINCIPAL AMOUNT OF LESS THAN
          $100,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH
          TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT, (D) OUTSIDE THE
          UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904
          UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM
          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF
          AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
          UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL DELIVER TO EACH
          PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE
          EFFECT OF THIS LEGEND. IN

          CONNECTION WITH ANY TRANSFER OF THIS NOTE WITHIN THE TIME PERIOD
          REFERRED TO ABOVE, THE HOLDER MUST CHECK THE APPROPRIATE BOX SET FORTH
          ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER AND
          SUBMIT THIS CERTIFICATE TO THE TRUSTEE. IF THE PROPOSED TRANSFEREE IS
          AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH
          TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH CERTIFICATIONS,
          LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY
          REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
          EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
          REQUIREMENTS OF THE SECURITIES ACT. AS USED HEREIN, THE TERMS
          "OFFSHORE TRANSACTION", "UNITED STATES" AND "U.S. PERSON" HAVE THE
          MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT. THE
          INDENTURE CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO
          REGISTER ANY TRANSFER OF THIS NOTE IN VIOLATION OF THE FOREGOING
          RESTRICTIONS.

          Each Global Note, whether or not an Exchange Note, shall also bear the
following legend on the face thereof:

          UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
          OF THE DEPOSITORY TRUST COMPANY, TO THE COMPANY OR ITS AGENT FOR
          REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE
          ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER ENTITY
          AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
          TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH
          OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE
          DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
          FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
          REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.


          TRANSFERS OF THIS GLOBAL NOTE SHALL BE LIMITED TO TRANSFERS IN WHOLE,
          BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF
          OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL
          NOTE SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE
          RESTRICTIONS SET FORTH IN SECTION 2.08 OF THE INDENTURE.

                                       27


     SECTION 2.03. EXECUTION, AUTHENTICATION AND DENOMINATIONS.

     Subject to Article Four and applicable law, the aggregate principal amount
of Notes which may be authenticated and delivered under this Indenture is
unlimited. The Notes shall be executed by two Officers of the Company. The
signature of these Officers on the Notes may be by facsimile or manual signature
in the name and on behalf of the Company.

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

     A Note shall not be valid until the Trustee manually signs the certificate
of authentication on the Note. The manually executed certificate of
authentication of the Trustee shall be conclusive evidence that the Note has
been authenticated under this Indenture.

     At any time and from time to time after the execution of this Indenture,
the Trustee shall upon receipt of a Company Order authenticate for original
issue Notes in the aggregate principal amount specified in such Company Order;
provided that the Trustee shall be entitled to receive an Officers' Certificate
and an Opinion of Counsel of the Company in connection with such authentication
of Notes. Such Company Order shall specify the amount of Notes to be
authenticated and the date on which the original issue of Notes is to be
authenticated and, in case of an issuance of Notes pursuant to Section 2.15,
shall certify that such issuance is in compliance with Article Four.

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


     The Notes shall be issuable only in registered form without coupons and
only in denominations of $1,000 in principal amount and any integral multiple
thereof.

     SECTION 2.04. REGISTRAR AND PAYING AGENT

     The Company shall maintain an office or agency where Notes may be presented
for registration of transfer or for exchange (the "REGISTRAR"), an office or
agency where Notes may be presented for payment (the "PAYING Agent") and an
office or agency where notices and demands to or upon the Company in respect of
the Notes and this Indenture may be served, which shall be in Boston,
Massachusetts and so long as the Notes are listed on the Luxembourg Stock
Exchange, in Luxembourg. The Company shall cause the Registrar to keep a
register of the Notes and of their transfer and exchange (the "SECURITY
REGISTER"). The Security Register shall be in written form or any other form
capable of being converted into written form within


   35


                                       28


a reasonable time. The Company may have one or more co-Registrars and one or
more additional Paying Agents.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture. The agreement shall implement the provisions of
this Indenture that relate to such Agent. The Company shall give prompt written
notice to the Trustee of the name and address of any such Agent and any change
in the address of such Agent. If the Company fails to maintain a Registrar,
Paying Agent and/or agent for service of notices and demands, the Trustee shall
act as such Registrar, Paying Agent and/or agent for service of notices and
demands. The Company may remove any Agent upon written notice to such Agent and
the Trustee; provided that no such removal shall become effective until (i) the
acceptance of an appointment by a successor Agent to such Agent as evidenced by
an appropriate agency agreement entered into by the Company and such successor
Agent and delivered to the Trustee or (ii) notification to the Trustee that the
Trustee shall serve as such Agent until the appointment of a successor Agent in
accordance with clause (i) of this proviso. The Company, any Subsidiary of the
Company, or any Affiliate of any of them may act as Paying Agent, Registrar or
co-Registrar, and/or agent for service of notice and demands.

     The Company initially appoints the Trustee as Registrar, Paying Agent,
authenticating agent and agent for service of notice and demands. The Trustee
shall preserve in as current a form as is reasonably practicable the most recent
list available to it of the names and addresses of Holders and shall otherwise
comply with TIA ss. 312(a). If the Trustee is not the Registrar, the Company
shall furnish to the Trustee as of each Regular Record Date and at such other
times as the Trustee may reasonably request the names and addresses of Holders
as they appear in the Security Register, including the aggregate principal
amount of Notes held by each Holder.

     SECTION 2.05. PAYING AGENT TO HOLD MONEY.

     Not later than 11:00 a.m. (New York City time) each due date of the
principal, premium, if any, and interest on any Notes, the Company shall deposit
with the Paying Agent money in immediately available funds sufficient to pay
such principal, premium, if any, and interest so becoming due. The Company shall
require each Paying Agent other than the Trustee to agree in writing that such
Paying Agent shall hold for the benefit of the Holders or the Trustee all money
held by the Paying Agent for the payment of principal of, premium, if any, and
interest on the Notes (whether such money has been paid to it by the Company or
any other obligor on the Notes), and such Paying Agent shall promptly notify the
Trustee of any default by the Company (or any other obligor on the Notes) in
making any such payment. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee and account for any funds disbursed, and
the Trustee may at any time during the continuance of any payment default, upon
written request to a Paying Agent, require such Paying Agent to pay all money
held by it to the Trustee and to account for any funds disbursed. Upon doing


   36


                                       29


so, the Paying Agent shall have no further liability for the money so paid over
to the Trustee. If the Company or any Subsidiary of the Company or any Affiliate
of any of them acts as Paying Agent, it will, on or before each due date of any
principal of, premium, if any, or interest on the Notes, segregate and hold in a
separate trust fund for the benefit of the Holders a sum of money sufficient to
pay such principal, premium, if any, or interest so becoming due until such sum
of money shall be paid to such Holders or otherwise disposed of as provided in
this Indenture, and will promptly notify the Trustee of its action or failure to
act.

     SECTION 2.06. TRANSFER AND EXCHANGE.

     The Notes are issuable only in registered form. A Holder may transfer a
Note only by written application to the Registrar stating the name of the
proposed transferee and otherwise complying with the terms of this Indenture. No
such transfer shall be effected until, and such transferee shall succeed to the
rights of a Holder only upon, final acceptance and registration of the transfer
by the Registrar in the Security Register. Prior to the registration of any
transfer by a Holder as provided herein, the Company, the Trustee, and any agent
of the Company shall treat the person in whose name the Note is registered as
the owner thereof for all purposes whether or not the Note shall be overdue, and
neither the Company, the Trustee, nor any such agent shall be affected by notice
to the contrary. Furthermore, any Holder of a Global Note shall, by acceptance
of such Global Note, agree that transfers of beneficial interests in such Global
Note may be effected only through a book entry system maintained by the Holder
of such Global Note (or its agent) and that ownership of a beneficial interest
in the Note shall be required to be reflected in a book entry. When Notes are
presented to the Registrar or a co-Registrar with a request to register the
transfer or to exchange them for an equal principal amount of Notes of other
authorized denominations (including an exchange of Notes for Exchange Notes),
the Registrar shall register the transfer or make the exchange as requested if
its requirements for such transactions are met (including that such Notes are
duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Trustee and Registrar duly executed by the Holder thereof or
by an attorney who is authorized in writing to act on behalf of the Holder);
provided that no exchanges of Notes for Exchange Notes shall occur until a
Registration Statement shall have been declared effective by the Commission and
that any Notes that are exchanged for Exchange Notes shall be canceled by the
Trustee. To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Notes at the Registrar's request. No
service charge shall be made for any registration of transfer or exchange or
redemption of the Notes, but the Company may require payment of a sum sufficient
to cover any transfer tax or similar governmental charge payable in connection
therewith (other than any such transfer taxes or other similar governmental
charge payable upon exchanges pursuant to Section 2.11, 3.08 or 9.04).

     The Registrar shall not be required (i) to issue, register the transfer of
or exchange any Note during a period beginning at the opening of business 15
days before the day of the mailing of a notice of redemption of Notes selected
for redemption under Section 3.03 and


   37


                                       30


ending at the close of business on the day of such mailing, or (ii) to register
the transfer of or exchange any Note so selected for redemption in whole or in
part, except the unredeemed portion of any Note being redeemed in part.

     SECTION 2.07. BOOK-ENTRY PROVISIONS FOR GLOBAL NOTES.

     (a) The U.S. Global Notes and Offshore Global Notes initially shall (i) be
registered in the name of the Depositary for such Global Notes or the nominee of
such Depositary, (ii) be delivered to the Trustee as custodian for such
Depositary and (iii) bear legends as set forth in Section 2.02.

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

     (b) Transfers of a Global Note shall be limited to transfers of such Global
Note in whole, but not in part, to the Depositary, its successors or their
respective nominees. Interests of beneficial owners in Global Notes may be
transferred in accordance with the rules and procedures of the Depositary and
the provisions of Section 2.08. In addition, U.S. Physical Notes and Offshore
Physical Notes shall be transferred to all beneficial owners in exchange for
their beneficial interests in the U.S. Global Notes or the Offshore Global
Notes, as the case may be, if (i) the Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for the U.S. Global Notes or the
Offshore Global Notes, as the case may be, and a successor depositary is not
appointed by the Company within 90 days of such notice, (ii) an Event of Default
has occurred and is continuing and the Registrar has received a request from the
Depositary or (iii) in accordance with the rules and procedures of the
Depositary and the provisions of Section 2.08.

     (c) Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in such other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.


   38


                                       31


     (d) In connection with any transfer of a portion of the beneficial
interests in a Global Note to beneficial owners pursuant to paragraph (b) of
this Section 2.07, the Registrar shall reflect on its books and records the date
and a decrease in the principal amount of such Global Note in an amount equal to
the principal amount of the beneficial interest in such Global Note to be
transferred, and the Company shall execute, and the Trustee shall authenticate
and deliver, one or more U.S. Physical Notes or Offshore Physical Notes, as the
case may be, of like tenor and amount.

     (e) In connection with the transfer of the U.S. Global Notes or the
Offshore Global Notes, in whole, to beneficial owners pursuant to paragraph (b)
of this Section 2.07, the U.S. Global Notes or Offshore Global Notes, as the
case may be, shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall authenticate and deliver,
to each beneficial owner identified by the Depositary in exchange for its
beneficial interest in the U.S. Global Notes or Offshore Global Notes, as the
case may be, an equal aggregate principal amount of U.S. Physical Notes or
Offshore Physical Notes, as the case may be, of authorized denominations.

     (f) Any U.S. Physical Note delivered in exchange for an interest in the
U.S. Global Notes pursuant to paragraph (b), (d) or (e) of this Section 2.07
shall, except as otherwise provided by paragraph (e) of Section 2.08, bear the
legend regarding transfer restrictions applicable to the U.S. Physical Note set
forth in Section 2.02.

     (g) Any Offshore Physical Note delivered in exchange for an interest in the
Offshore Global Notes pursuant to paragraph (b), (d) or (e) of this Section 2.07
shall, except as otherwise provided by paragraph (f) of Section 2.08, bear the
legend regarding transfer restrictions applicable to the Offshore Physical Note
set forth in Section 2.02.

     (h) The registered holder of a Global Note may grant proxies and otherwise
authorize any person, including Agent Members and persons that may hold
interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Notes.

     SECTION 2.08. SPECIAL TRANSFER PROVISIONS.

     Unless and until a Note is exchanged for an Exchange Note or sold in
connection with an effective Registration Statement pursuant to the Registration
Rights Agreement, the following provisions shall apply:

     (a) TRANSFERS TO NON-QIB INSTITUTIONAL ACCREDITED INVESTORS. The following
provisions shall apply with respect to the registration of any proposed transfer
of a Note to any Institutional Accredited Investor which is not a QIB (excluding
Non-U.S. Persons):


   39


                                       32


          (i) The Registrar shall register the transfer of any Note, whether or
     not such Note bears the Private Placement Legend, if (x) the requested
     transfer is after the time period referred to in Rule 144(k) under the
     Securities Act or (y) the proposed transferee has delivered to the
     Registrar (A) a certificate substantially in the form of Exhibit C hereto
     and (B) if the aggregate principal amount of the Notes being transferred is
     less than $100,000, an opinion of counsel acceptable to the Company that
     such transfer is in compliance with the Securities Act.

          (ii) If the proposed transferor is an Agent Member holding a
     beneficial interest in the U.S. Global Notes, upon receipt by the Registrar
     of (x) the documents, if any, required by paragraph (i) above and (y)

     amount equal to the principal amount of the beneficial interest in the U.S.
     Global Notes to be transferred, and the Company shall execute, and the
     Trustee shall authenticate and deliver, one or more U.S. Physical Notes of
     like tenor and amount.

     (b) TRANSFERS TO QIBS. The following provisions shall apply with respect to

Persons):

          (i) If the Note to be transferred consists of (x) either Offshore
     Physical Notes prior to the removal of the Private Placement Legend or U.S.
     Physical Notes, the Registrar shall register the transfer if such transfer
     is being made by a proposed transferor who has checked the box provided for
     on the form of Note stating, or has otherwise advised the Company and the
     Registrar in writing, that the sale has been made in compliance with the
     provisions of Rule 144A to a transferee who has signed the certification
     provided for on the form of Note stating, or has otherwise advised the
     Company and the Registrar in writing, that it is purchasing the Note for
     its own account or an account with respect to which it exercises sole
     investment discretion and that it and any such account is a QIB within the
     meaning of Rule 144A and is aware that the sale to it is being made in
     reliance on Rule 144A and acknowledges that it has received such
     information regarding the Company as it has requested pursuant to Rule 144A
     or has determined not to request such information and that it is aware that
     the transferor is relying upon its foregoing representations in order to
     claim the exemption from registration provided by Rule 144A or (y) an
     interest in the U.S. Global Notes, the transfer of such interest may be
     effected only through the book entry system maintained by the Depositary.

          (ii) If the proposed transferee is an Agent Member, and the Note to be
     transferred consists of U.S. Physical Notes, upon receipt by the Registrar
     of the documents referred to in paragraph (i) above and instructions given
     in accordance with 


   40


                                       33


     the Depositary's and the Registrar's procedures, the Registrar shall

     amount of U.S. Global Notes in an amount equal to the principal amount of
     the U.S. Physical Notes to be transferred, and the Trustee shall cancel the
     U.S. Physical Notes so transferred.

          (i) prior to the removal of the Private Placement Legend from the

     the Registrar shall refuse to register such transfer unless such transfer
     complies with Section 2.08(b) or Section 2.08(d), as the case may be, and

          (ii) after such removal, the Registrar shall register the transfer of
     any such Note without requiring any additional certification.

          (i) The Registrar shall register any proposed transfer to any Non-U.S.

     in U.S. Global Notes, upon receipt of a certificate substantially in the
     form of Exhibit D hereto from the proposed transferor.

          (ii) (a) If the proposed transferor is an Agent Member holding a
     beneficial interest in the U.S. Global Notes, upon receipt by the Registrar
     of (x) the documents, if any, required by paragraph (ii) and (y)
     instructions in accordance with the Depositary's and the Registrar's
     procedures, the Registrar shall reflect on its books and records the date
     and a decrease in the principal amount of the U.S. Global Notes in an
     amount equal to the principal amount of the beneficial interest in the U.S.
     Global Notes to be transferred, and (b) if the proposed transferee is an

     as the case may be, to be transferred, and the Trustee shall cancel the
     Physical Note, if any, so transferred or decrease the amount of the U.S.
     Global Notes.

     (e) PRIVATE PLACEMENT LEGEND. Upon the transfer, exchange or replacement of
Notes not bearing the Private Placement Legend, the Registrar shall deliver
Notes that do not


   41


                                       34


bear the Private Placement Legend. Upon the transfer, exchange or replacement of
Notes bearing the Private Placement Legend, the Registrar shall deliver only
Notes that bear the Private Placement Legend unless either (i) the circumstances
contemplated by paragraph (a)(i)(x) or (c)(ii) of this Section 2.08 exist or
(ii) there is delivered to the Registrar an Opinion of Counsel reasonably
satisfactory to the Company and the Trustee to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act.

     (f) GENERAL. By its acceptance of any Note bearing the Private Placement
Legend, each Holder of such a Note acknowledges the restrictions on transfer of
such Note set forth in this Indenture and in the Private Placement Legend and
agrees that it will transfer such Note only as provided in this Indenture. The
Registrar shall not register a transfer of any Note unless such transfer
complies with the restrictions on transfer of such Note set forth in this
Indenture. In connection with any transfer of Notes, each Holder agrees by its
acceptance of the Notes to furnish the Registrar or the Company such
certifications, legal opinions or other information as either of them may
reasonably require to confirm that such transfer is being made pursuant to an
exemption from, or a transaction not subject to, the registration requirements
of the Securities Act; provided that the Registrar shall not be required to
determine (but may rely on a determination made by the Company with respect to)
the sufficiency of any such certifications, legal opinions or other information.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.07 or this Section 2.08. The
Company shall have the right to inspect and make copies of all such letters,
notices or other written communications at any reasonable time upon the giving
of reasonable written notice to the Registrar.

     SECTION 2.09. REPLACEMENT NOTES SECTION.

     If a mutilated Note is surrendered to the Trustee or if the Holder claims
that the Note has been lost, destroyed or wrongfully taken, then, in the absence
of notice to the Company or the Trustee that such Note has been acquired by a
bona fide purchaser, the Company shall issue and the Trustee shall authenticate
a replacement Note of like tenor and principal amount and bearing a number not
contemporaneously outstanding; provided that the requirements of this Section
2.09 are met. If required by the Trustee or the Company, an indemnity bond must
be furnished that is sufficient in the judgment of both the Trustee and the
Company to protect the Company, the Trustee or any Agent from any loss that any
of them may suffer if a Note is replaced. The Company may charge such Holder for
its expenses and the expenses of the Trustee in replacing a Note. In case any
such mutilated, lost, destroyed or wrongfully taken Note has become or is about
to become due and payable, the Company in its discretion may pay such Note
instead of issuing a new Note in replacement thereof.


   42


                                       35


     Every replacement Note is an additional obligation of the Company and shall
be entitled to the benefits of this Indenture.

     SECTION 2.10. OUTSTANDING NOTES.

     Notes outstanding at any time are all Notes that have been authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section 2.10 as not outstanding.

     If a Note is replaced pursuant to Section 2.09, it ceases to be outstanding
unless and until the Trustee and the Company receive proof satisfactory to them
that the replaced Note is held by a bona fide purchaser.

     If the Paying Agent (other than the Company or an Affiliate of the Company)
holds on the maturity date money sufficient to pay Notes payable on that date,
then on and after that date such Notes cease to be outstanding and interest on
them shall cease to accrue.

     A Note does not cease to be outstanding because the Company or one of its
Affiliates holds such Note, provided, however, that in determining whether the
Holders of the requisite principal amount of the outstanding Notes have given
any request, demand, authorization, direction, notice, consent or waiver
hereunder, Notes owned by the Company or any other obligor upon the Notes or any
Affiliate of the Company or of such other obligor shall be disregarded and
deemed not to be outstanding, except that, in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Notes which the Trustee has actual
knowledge to be so owned shall be so disregarded. Notes so owned which have been
pledged in good faith may be regarded as outstanding if the pledgee establishes
to the satisfaction of the Trustee the pledgee's right so to act with respect to
such Notes and that the pledgee is not the Company or any other obligor upon the
Notes or any Affiliate of the Company or of such other obligor.

     SECTION 2.11. TEMPORARY NOTES.

     Until definitive Notes are ready for delivery, the Company may prepare and
execute and the Trustee shall authenticate temporary Notes. Temporary Notes
shall be substantially in the form of definitive Notes but may have insertions,
substitutions, omissions and other variations determined to be appropriate by
the Officers executing the temporary Notes, as evidenced by their execution of
such temporary Notes. If temporary Notes are issued, the Company will cause
definitive Notes to be prepared without unreasonable delay. After the
preparation of definitive Notes, the temporary Notes shall be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for such purpose pursuant to Section 4.02, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Notes the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Notes


   43


                                       36


of authorized denominations. Until so exchanged, the temporary Notes shall be
entitled to the same benefits under this Indenture as definitive Notes.

     SECTION 2.12. CANCELLATION.

     The Company at any time may deliver to the Trustee for cancellation any
Notes previously authenticated and delivered hereunder which the Company may
have acquired in any manner whatsoever, and may deliver to the Trustee for
cancellation any Notes previously authenticated hereunder which the Company has
not issued and sold. The Registrar and the Paying Agent shall forward to the
Trustee any Notes surrendered to them for transfer, exchange or payment. The
Trustee shall cancel all Notes surrendered for transfer, exchange, payment or
cancellation and shall destroy them in accordance with its normal procedure.

     SECTION 2.13. CUSIP NUMBERS.

     The Company in issuing the Notes may use "CUSIP", "CINS" or "ISIN" numbers
(if then generally in use), and the Company and the Trustee shall use CUSIP,
CINS or ISIN numbers, as the case may be, in notices of redemption or exchange
as a convenience to Holders; provided that any such notice shall state that no
representation is made as to the correctness of such numbers either as printed
on the Notes or as contained in any notice of redemption or exchange and that
reliance may be placed only on the other identification numbers printed on the
Notes. The Company shall promptly notify the Trustee of any change in "CUSIP",
"CINS" or "ISIN" numbers for the Notes.

     SECTION 2.14. DEFAULTED INTEREST.

     If the Company defaults in a payment of interest on the Notes, it shall
pay, or shall deposit with the Paying Agent money in immediately available funds
sufficient to pay, the defaulted interest, plus (to the extent lawful) any
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date. A special record date, as used in this Section
2.14 with respect to the payment of any defaulted interest, shall mean the 15th
day next preceding the date fixed by the Company for the payment of defaulted
interest, whether or not such day is a Business Day. At least 15 days before the
subsequent special record date, the Company shall mail to each Holder and to the
Trustee a notice that states the subsequent special record date, the payment
date and the amount of defaulted interest to be paid.

     SECTION 2.15. ISSUANCE OF ADDITIONAL NOTES.

     The Company may, subject to Article Four of this Indenture and applicable
law, issue additional Notes under this Indenture. The Notes issued on the
Closing Date and any additional Notes subsequently issued shall be treated as a
single class for all purposes under this Indenture.

                                   REDEMPTION


     SECTION 3.01. RIGHT OF REDEMPTION.

     (a) The Notes are redeemable, at the Company's option, in whole or in part,
at any time or from time to time, on or after June 15, 2003 and prior to
maturity, upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's last address, as it appears in the Security
Register, at the following Redemption Prices (expressed in percentages of
principal amount), plus accrued and unpaid interest, if any, to the Redemption
Date (subject to the right of Holders of record on the relevant Regular Record
Date that is prior to the Redemption Date to receive interest due on an Interest
Payment Date), if redeemed during the 12-month period commencing June 15 of the
years set forth below:

                                                          Redemption
            Year                                             Price

            2004...............................            103.167
            2005...............................            101.583
            2006 and thereafter................            100.000

     (b) In addition, at any time prior to June 15, 2001, the Company may redeem
up to 35% of the aggregate principal amount of the Notes with the proceeds of
one or more Equity Offerings, at a Redemption Price of 109.50%, plus accrued and
unpaid interest to the Redemption Date (subject to the rights of Holders of
record on the relevant Regular Record Date that is prior to the Redemption Date
to receive interest due on an Interest Payment Date); provided that (i) Notes
representing 65% of the principal amount of Notes initially issued remain
outstanding after each such redemption and (ii) notice of such redemption is
mailed within 60 days of the related Equity Offering.

     (c) Prior to June 15, 2003, the Notes will be redeemable at the Company's
option, in whole or in part, at any time or from time to time, upon not less
than 30 nor more than 60 days' prior notice mailed by first class mail to each
Holder's registered address, at a redemption price (expressed as a percentage of
principal amount) equal to the sum of the principal amount such Notes plus the
Applicable Premium thereon at the time of redemption (an "Early Redemption
Date") (subject to the right of holders of record on the relevant record date to
receive due on the relevant interest payment date).

     SECTION 3.02. NOTICES TO TRUSTEE.

     If the Company elects to redeem Notes pursuant to Section 3.01, it shall
notify the Trustee in writing of the Redemption Date and the principal amount of
Notes to be redeemed and the clause of this Indenture pursuant to which
redemption shall occur.


   45


                                       38


     The Company shall give each notice provided for in this Section 3.02 in an
Officers' Certificate at least 45 days before the Redemption Date (unless a
shorter period shall be satisfactory to the Trustee).

     SECTION 3.03. SELECTION OF NOTES TO BE REDEEMED.

     In the case of partial redemption, selection of the Notes for redemption
shall be made by the Trustee in compliance with the requirements, as certified
to it by the Company, of the principal national securities exchange, if any, on
which the Notes are listed or, if the Notes are not listed on a national
securities exchange or automated quotation system, by lot, pro rata or by such
other method as the Trustee in its sole discretion shall deem fair and
appropriate or, as to any Notes in global form, in accordance with the
procedures of the Depository; provided that no Note of $1,000 in principal
amount or less shall be redeemed in part.

     The Trustee shall make the selection from the Notes outstanding and not
previously called for redemption. Notes in denominations of $1,000 in principal
amount may only be redeemed in whole. The Trustee may select for redemption
portions (equal to $1,000 in principal amount or any integral multiple thereof)
of Notes that have denominations larger than $1,000 in principal amount.
Provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption. The Trustee shall notify the
Company and the Registrar promptly in writing of the Notes or portions of Notes
to be called for redemption.

     SECTION 3.04. NOTICE OF REDEMPTION.

     With respect to any redemption of Notes pursuant to Section 3.01, at least
30 days but not more than 60 days before a Redemption Date, the Company shall
mail a notice of redemption by first-class mail to each Holder whose Notes are
to be redeemed.

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

          (i) the Redemption Date;

          (ii) the Redemption Price;

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

          (iv) that Notes called for redemption must be surrendered to the
     Paying Agent in order to collect the Redemption Price;

          (v) that, unless the Company defaults in making the redemption
     payment, interest on Notes called for redemption ceases to accrue on and
     after the Redemption


   46


                                       39


     Date and the only remaining right of the Holders is to receive payment of
     the Redemption Price plus accrued interest to the Redemption Date upon
     surrender of the Notes to the Paying Agent;

          (vi) that, if any Note is being redeemed in part, the portion of the
     principal amount (equal to $1,000 in principal amount or any integral
     multiple thereof) of such Note to be redeemed and that, on and after the
     Redemption Date, upon surrender of such Note, a new Note or Notes in
     principal amount equal to the unredeemed portion thereof will be reissued;
     and

          (vii) that, if any Note contains a CUSIP, CINS or ISIN number as
     provided in Section 2.13, no representation is being made as to the
     correctness of the CUSIP, CINS or ISIN number either as printed on the
     Notes or as contained in the notice of redemption and that reliance may be
     placed only on the other identification numbers printed on the Notes.

     At the Company's request (which request may be revoked by the Company at
any time prior to the time at which the Trustee shall have given such notice to
the Holders), made in writing to the Trustee at least 45 days (or such shorter
period as shall be satisfactory to the Trustee) before a Redemption Date, the
Trustee shall give the notice of redemption in the name and at the expense of
the Company. If, however, the Company gives such notice to the Holders, the
Company shall concurrently deliver to the Trustee an Officers' Certificate
stating that such notice has been given.

     SECTION 3.05. EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed, Notes called for redemption become due
and payable on the Redemption Date and at the Redemption Price. Upon surrender
of any Notes to the Paying Agent, such Notes shall be paid at the Redemption
Price, plus accrued interest, if any, to the Redemption Date.

     Notice of redemption shall be deemed to be given when mailed, whether or
not the Holder receives the notice. In any event, failure to give such notice,
or any defect therein, shall not affect the validity of the proceedings for the
redemption of Notes held by Holders to whom such notice was properly given.

     SECTION 3.06. DEPOSIT OF REDEMPTION PRICE.

     On or prior to the Business Day immediately preceding any Redemption Date,
the Company shall deposit with the Paying Agent (or, if the Company is acting as
its own Paying Agent, shall segregate and hold in trust as provided in Section
2.05) money sufficient to pay the Redemption Price of and accrued interest on
all Notes to be redeemed on that date other than Notes or portions thereof
called for redemption on that date that have been delivered by the Company to
the Trustee for cancellation.

                                       40


     SECTION 3.07. PAYMENT OF NOTES CALLED FOR REDEMPTION.

     If notice of redemption has been given in the manner provided above, the
Notes or portion of Notes specified in such notice to be redeemed shall become
due and payable on the Redemption Date at the Redemption Price stated therein,
together with accrued interest to such Redemption Date, and on and after such
date (unless the Company shall default in the payment of such Notes at the
Redemption Price and accrued interest to the Redemption Date, in which case the
principal, until paid, shall bear interest from the Redemption Date at the rate
prescribed in the Notes), such Notes shall cease to accrue interest. Upon
surrender of any Note for redemption in accordance with a notice of redemption,
such Note shall be paid and redeemed by the Company at the Redemption Price,
together with accrued interest, if any, to the Redemption Date; provided that
installments of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders registered as such at the close of business
on the relevant Regular Record Date.


     SECTION 3.08. NOTES REDEEMED IN PART.

     Upon surrender and cancellation of any Note that is redeemed in part, the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder without service charge, a new Note equal in principal amount to the
unredeemed portion of such surrendered Note.


                                  ARTICLE FOUR
                                    COVENANTS

     SECTION 4.01. PAYMENT OF NOTES.

     The Company shall pay the principal of, premium, if any, and interest on
the Notes on the dates and in the manner provided in the Notes and this
Indenture. An installment of principal, premium, if any, or interest shall be
considered paid on the date due if the Trustee or Paying Agent (other than the
Company, a Subsidiary of the Company, or any Affiliate of any of them) holds on
that date money designated for and sufficient to pay the installment. If the
Company or any Subsidiary of the Company or any Affiliate of any of them acts as
Paying Agent, an installment of principal, premium, if any, or interest shall be
considered paid on the due date if the entity acting as Paying Agent complies
with the last sentence of Section 2.05. As provided in Section 6.09, upon any
bankruptcy or reorganization procedure relative to the Company, the Trustee
shall serve as the Paying Agent, if any, for the Notes.

     The Company shall pay interest on overdue principal and premium, if any,
and interest on overdue installments of interest, to the extent lawful, at the
rate per annum specified in the Notes.

                                       41


     SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY.

     The Company will maintain in Boston, Massachusetts and, so long as the
Notes are listed on the Luxembourg Stock Exchange, in Luxembourg, an office or
agency where Notes may be surrendered for registration of transfer or exchange
or for presentation for payment and where notices and demands to or upon the
Company in respect of the Notes and this Indenture may be served. The Company
will give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the address of the Trustee set forth in Section
10.02.

     The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided that no
such designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in Boston, Massachusetts and, so long
as the Notes are listed on the Luxembourg Stock Exchange, in Luxembourg, for
such purposes. The Company shall give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such
other office or agency.

     The Company hereby initially designates the Corporate Trust Office of the
Trustee as such office of the Company in accordance with Section 2.04.

     SECTION 4.03. LIMITATION ON INDEBTEDNESS.

     (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, Incur any Indebtedness (other than the Notes and Indebtedness
existing on the Closing Date, whether or not any such Indebtedness existing on
the Closing Date is repaid or reborrowed ); provided that the Company and any
Guarantor may Incur Indebtedness if, after giving effect to the Incurrence of
such Indebtedness and the receipt and application of the proceeds therefrom, the
Interest Coverage Ratio would be greater than 3:1.

     Notwithstanding the foregoing and, in addition to Indebtedness permitted by
the foregoing paragraph, the Company and any Restricted Subsidiary (except as
specified below) may Incur each and all of the following: (i) Indebtedness of
the Company and the Guarantors outstanding at any time in an aggregate principal
amount not to exceed the commitments under the Credit Facility on the Closing
Date; (ii) Indebtedness owed (A) to the Company evidenced by an unsubordinated
promissory note or (B) to any Restricted Subsidiary; provided that any event
which results in any such Restricted Subsidiary ceasing to be a Restricted
Subsidiary or any subsequent transfer of such Indebtedness (other than to the
Company or another Restricted Subsidiary) shall be deemed, in each case, to
constitute an Incurrence of such Indebtedness not permitted by this clause (ii);
(iii) Indebtedness issued in exchange for, or the net proceeds of


   49


                                       42


which are used to refinance or refund, then outstanding Indebtedness (other than
Indebtedness Incurred under clause (i), (ii), (iv), (vi) or (vii) of this
paragraph; it being understood that Indebtedness Incurred under such clauses can
be refinanced thereunder) and any refinancings thereof in an amount not to
exceed the amount so refinanced or refunded (plus premiums, accrued interest,
fees and expenses); provided that Indebtedness the proceeds of which are used to
refinance or refund the Notes or Indebtedness that is pari passu with, or
subordinated in right of payment to, the Notes shall only be permitted under
this clause (iii) if (A) in case the Notes are refinanced in part or the
Indebtedness to be refinanced is pari passu with the Notes, such new
Indebtedness, by its terms or by the terms of any agreement or instrument
pursuant to which such new Indebtedness is outstanding, is expressly made pari
passu with, or subordinate in right of payment to, the remaining Notes, (B) in
case the Indebtedness to be refinanced is subordinated in right of payment to
the Notes, such new Indebtedness, by its terms or by the terms of any agreement
or instrument pursuant to which such new Indebtedness is issued or remains
outstanding, is expressly made subordinate in right of payment to the Notes at
least to the extent that the Indebtedness to be refinanced is subordinated to
the Notes and (C) such new Indebtedness, determined as of the date of Incurrence
of such new Indebtedness, does not mature prior to the Stated Maturity of the
Indebtedness to be refinanced or refunded, and the Average Life of such new
Indebtedness is at least equal to the remaining Average Life of the Indebtedness
to be refinanced or refunded; and provided further that in no event may
Indebtedness of the Company be refinanced by means of any Indebtedness of any
Restricted Subsidiary pursuant to this clause (iii); (iv) Indebtedness (A) in
respect of performance, surety or appeal bonds provided in the ordinary course
of business, (B) under Currency Agreements and Interest Rate Agreements;
provided that such agreements (a) are designed solely to protect the Company or
its Restricted Subsidiaries against fluctuations in foreign currency exchange
rates or interest rates and (b) do not increase the Indebtedness of the obligor
outstanding at any time other than as a result of fluctuations in foreign
currency exchange rates or interest rates or by reason of fees, indemnities and
compensation payable thereunder; and (C) arising from agreements providing for
indemnification, adjustment of purchase price, earn outs or similar obligations,
or from Guarantees or letters of credit, surety bonds or performance bonds
securing any obligations of the Company or any of its Restricted Subsidiaries
pursuant to such agreements, in any case Incurred in connection with the
disposition of any business, assets or Restricted Subsidiary (other than
Guarantees of Indebtedness Incurred by any Person acquiring all or any portion
of such business, assets or Restricted Subsidiary for the purpose of financing
such acquisition), in a principal amount not to exceed the gross proceeds
actually received by the Company or any Restricted Subsidiary in connection with
such disposition; (v) Indebtedness of the Company and any Guarantor, to the
extent the net proceeds thereof are promptly (A) used to purchase Notes tendered
in an Offer to Purchase made as a result of a Change in Control or (B) deposited
to defease the Notes pursuant to Article Eight; (vi) Guarantees of the Notes and
Guarantees of Indebtedness of the Company by any Restricted Subsidiary provided
the Guarantee of such Indebtedness is permitted by and made in accordance with
Section 4.08;


   50


                                       43

(vii) Indebtedness under the Notes and the Note Guarantees (as well as the notes
issued upon the exchange of the Notes); (viii) Indebtedness of the Company or
any Guarantor constituting Purchase Money Indebtedness or Capitalized Lease
Obligations that do not, at any one time outstanding, exceed 10% of the Adjusted
Consolidated Net Tangible Assets of the Company and the Guarantors; (ix)
Indebtedness of the Company, the Guarantors and the Foreign Subsidiaries of the
Company outstanding at any time in the aggregate principal amount not to exceed
$100 million; and (x) Indebtedness of the Company and the Guarantors (in
addition to Indebtedness permitted under clauses (i) through (ix) above) in an
aggregate principal amount outstanding at any time not to exceed $50 million.

     (b) With respect to any particular Indebtedness, notwithstanding any other
provision of this Section 4.03, the maximum amount of Indebtedness that the
Company or a Restricted Subsidiary may Incur pursuant to this Section 4.03 shall
not be deemed to be exceeded due solely to the result of fluctuations in the
exchange rates of currencies.

     (c) For purposes of determining any particular amount of Indebtedness under
this Section 4.03, (1) Guarantees, Liens or obligations with respect to letters
of credit supporting Indebtedness otherwise included in the determination of
such particular amount shall not be included and (2) any Liens granted pursuant
to the equal and ratable provisions referred to in Section 4.10 shall not be
treated as Indebtedness. For purposes of determining compliance with this
Section 4.10, in the event that an item of Indebtedness meets the criteria of
more than one of the types of Indebtedness described in the above clauses, the
Company, in its sole discretion, shall classify, and from time to time may
reclassify, such item of Indebtedness and only be required to include the amount
and type of such Indebtedness in one of such clauses. No Indebtedness incurred
pursuant to the first paragraph of Section (a) of this Section 4.03 shall be
included in calculating any limitation set forth in clauses (i) through (x), of
such Section (a).

     SECTION 4.04. LIMITATION ON SENIOR SUBORDINATED INDEBTEDNESS.

     The Company and the Guarantors shall not Incur any Indebtedness that is
subordinate in right of payment to any Senior Indebtedness unless such
Indebtedness is pari passu with, or subordinated in right of payment to, the
Notes or the Note Guarantee of such Guarantor, as the case may be; provided that
the foregoing limitation shall not apply to distinctions between categories of
Senior Indebtedness that exist by reason of any Liens or Guarantees arising or
created in respect of some but not all Senior Indebtedness.

     SECTION 4.05. LIMITATION ON RESTRICTED PAYMENTS.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, (i) declare or pay any dividend or make any distribution
on or with respect to its Capital Stock (other than (x) dividends or
distributions payable solely in shares of its Capital Stock (other than
Disqualified Stock) or in options, warrants or other rights to


   51


                                       44


acquire shares of such Capital Stock and (y) pro rata dividends or distributions
on Common Stock of Restricted Subsidiaries held by minority stockholders) held
by Persons other than the Company or any of its Restricted Subsidiaries, (ii)
purchase, redeem, retire or otherwise acquire for value any shares of Capital
Stock of (A) the Company or an Unrestricted Subsidiary (including options,

rights to acquire such shares of Capital Stock) held by any Affiliate of the
Company (other than a Wholly Owned Restricted Subsidiary) or any holder (or any
Affiliate of such holder) of 5% or more of the Capital Stock of the Company,
(iii) make any voluntary or optional principal payment, or voluntary or optional
redemption, repurchase, defeasance, or other acquisition or retirement for
value, of Indebtedness of the Company that is subordinated in right of payment
to the Notes or (iv) make any Investment, other than a Permitted Investment, in
any Person (such payments or any other actions described in clauses (i) through
(iv) above being collectively "Restricted Payments") if, at the time of, and
after giving effect to, the proposed Restricted Payment: (A) a Default or Event
of Default shall have occurred and be continuing, (B) the Company could not
Incur at least $1.00 of Indebtedness under the first paragraph of Section 4.03
or (C) the aggregate amount of all Restricted Payments (the amount, if other
than in cash, to be determined in good faith by the Board of Directors, whose
determination shall be conclusive and evidenced by a Board Resolution) made
after the Closing Date shall exceed the sum of (1) 50% of the aggregate amount
of the Adjusted Consolidated Net Income (or, if the Adjusted Consolidated Net
Income is a loss, minus 100% of the amount of such loss) (determined by
excluding income resulting from transfers of assets by the Company or a
Restricted Subsidiary to an Unrestricted Subsidiary) accrued on a cumulative
basis during the period (taken as one accounting period) beginning on the first
day of the fiscal quarter immediately following the Closing Date and ending on
the last day of the last fiscal quarter preceding the Transaction Date for which
reports have been filed with the Commission or provided to the Trustee pursuant
to Section 4.18 plus (2) the aggregate Net Cash Proceeds received by the Company
after the Closing Date from the issuance and sale permitted by this Indenture of
its Capital Stock (other than Disqualified Stock) to a Person who is not a
Subsidiary of the Company, including an issuance or sale permitted by this
Indenture of Indebtedness of the Company for cash subsequent to the Closing Date
upon the conversion of such Indebtedness into Capital Stock (other than
Disqualified Stock) of the Company, or from the issuance to a Person who is not
a Subsidiary of the Company of any options, warrants or other rights to acquire
Capital Stock of the Company (in each case, exclusive of any Disqualified Stock
or any options, warrants or other rights that are redeemable at the option of
the holder, or are required to be redeemed, prior to the Stated Maturity of the
Notes) plus (3) an amount equal to the net reduction in Investments (other than
reductions in Permitted Investments or Investments made pursuant to the
following paragraph) in any Person resulting from payments of interest on
Indebtedness, dividends, repayments of loans or advances, or other transfers of
assets, in each case to the Company or any Restricted Subsidiary or from the Net
Cash Proceeds from the sale of any such Investment (except, in each case, to the
extent 


   52


                                       45


any such payment or proceeds are included in the calculation of Adjusted
Consolidated Net Income), or from redesignations of Unrestricted Subsidiaries as
Restricted Subsidiaries (valued in each case as provided in the definition of
"Investments"), not to exceed, in each case, the amount of Investments
previously made by the Company or any Restricted Subsidiary in such Person or
Unrestricted Subsidiary plus (4) $5 million.

     The foregoing provision shall not be violated by reason of: (i) the payment
of any dividend or distribution within 60 days after the date of declaration
thereof if, at said date of declaration, such payment would comply with the
foregoing paragraph; (ii) the redemption, repurchase, defeasance or other
acquisition or retirement for value of Indebtedness that is subordinated in
right of payment to the Notes including premium, if any, and accrued and unpaid
interest, with the proceeds of, or in exchange for, Indebtedness Incurred under
clause (iii) of the second paragraph of part (a) of Section 4.03(a); (iii) the
repurchase, redemption or other acquisition of Capital Stock of the Company or
an Unrestricted Subsidiary (or options, warrants or other rights to acquire such
Capital Stock) in exchange for, or out of the proceeds of a substantially
concurrent offering of, shares of Capital Stock (other than Disqualified Stock)
of the Company (or options, warrants or other rights to acquire such Capital
Stock); (iv) the making of any principal payment or the repurchase, redemption,
retirement, defeasance or other acquisition for value of Indebtedness of the
Company which is subordinated in right of payment to the Notes in exchange for,
or out of the proceeds of, a substantially concurrent offering of, shares of the
Capital Stock (other than Disqualified Stock) of the Company (or options,
warrants or other rights to acquire such Capital Stock); (v) payments or
distributions, to dissenting stockholders pursuant to applicable law, pursuant
to or in connection with a consolidation, merger or transfer of assets that
complies with the provisions of Article Five; (vi) Restricted Payments not to
exceed $30 million (provided that to the extent such Restricted Payment is an
Investment, Investments not to exceed $30 million at any one time outstanding);
or (vii) Investments acquired in exchange for Capital Stock (other than
Disqualified Stock) of the Company (or options, warrants or other rights to
acquire such Capital Stock) or financed or refinanced out of the proceeds of a
substantially concurrent offering of shares of Capital Stock of the Company (or
options, warrants or other rights to acquire such Capital Stock); provided that,
except in the case of clauses (i) and (iii), no Default or Event of Default
shall have occurred and be continuing or occur as a consequence of the actions
or payments set forth therein.

     Each Restricted Payment permitted pursuant to the preceding paragraph
(other than the Restricted Payment referred to in clause (ii) thereof, an
exchange of Capital Stock for Capital Stock or Indebtedness referred to in
clause (iii) or (iv) thereof and an Investment referred to in clause (vi)
thereof), and the Net Cash Proceeds from any issuance of Capital Stock referred
to in clauses (iii) and (iv), shall be included in calculating whether the
conditions of clause (C) of the first paragraph of this Section 4.05 have been
met with respect to any subsequent Restricted Payments. In the event the
proceeds of an issuance of Capital Stock of the 


   53


                                       46


Company are used for the redemption, repurchase or other acquisition of the
Notes, or Indebtedness that is pari passu with the Notes, then the Net Cash
Proceeds of such issuance shall be included in clause (C) of the first paragraph
of this Section 4.05 only to the extent such proceeds are not used for such
redemption, repurchase or other acquisition of Indebtedness.

     The amount of any Investment "outstanding" at any time shall be deemed to
be equal to the amount of such Investment on the date made, less the return on
capital to the Company and its Restricted Subsidiaries with respect to such
Investment by distribution, sale or otherwise (up to the amount of such
Investment on the date made).

     SECTION 4.06. LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS
AFFECTING RESTRICTED SUBSIDIARIES.


     The Company will not, and will not permit any Restricted Subsidiary to,
create or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction of any kind on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions permitted by
applicable law on any Capital Stock of such Restricted Subsidiary owned by the
Company or any other Restricted Subsidiary, (ii) pay any Indebtedness owed to
the Company or any other Restricted Subsidiary, (iii) make loans or advances to
the Company or any other Restricted Subsidiary or (iv) transfer any of its
property or assets to the Company or any other Restricted Subsidiary.


     The foregoing provisions shall not restrict any encumbrances or
restrictions: (i) existing on the Closing Date in the Credit Facility, this
Indenture or any other agreements in effect on the Closing Date, and any
amendments, modifications, supplements, extensions, refinancings, renewals or
replacements of such agreements; provided that the encumbrances and restrictions
in any such amendments, modifications, supplements, extensions, refinancings,
renewals or replacements are no less favorable in any material respect to the
Holders than those encumbrances or restrictions that are then in effect and that
are being amended, modified, supplemented, extended, refinanced, renewed or
replaced; (ii) existing under or by reason of applicable law; (iii) under any
instrument governing Acquired Indebtedness incurred in accordance with this
Indenture; provided that such encumbrances or restrictions are not adopted in
contemplation of the related acquisition; (iv) in the case of clause (iv) of the
first paragraph of this Section 4.06, (A) that restrict in a customary manner
the subletting, assignment or transfer of any property or asset that is a lease,
license, conveyance or contract or similar property or asset, (B) existing by
virtue of any transfer of, agreement to transfer, option or right with respect
to, or Lien on, any property or assets of the Company or any Restricted
Subsidiary not otherwise prohibited by this Indenture or (C) arising or agreed
to in the ordinary course of business, not relating to any Indebtedness, and
that do not, individually or in the aggregate, detract from the value of
property or assets of the Company or any Restricted Subsidiary in any manner
material to the Company or any 


   54


                                       47


Restricted Subsidiary; (v) with respect to a Restricted Subsidiary and imposed
pursuant to an agreement that has been entered into for the sale or disposition
of all or substantially all of the Capital Stock of, or property and assets of,
such Restricted Subsidiary; and (vi) with respect to any Foreign Subsidiary;
provided that (A) the Investments of the Company and its Subsidiaries in such
Foreign Subsidiary are, as determined by the Board of Directors, not made for
the purpose of removing assets from the Company and the Guarantors which
removal, in the judgment of the Board of Directors, would be likely to have a
material adverse impact on the Company's ability to make payments on the Notes
and (B) such encumbrances or restrictions are not, in the judgment of the Board
of Directors, likely to have a material adverse impact on the Company's ability
to make payments on the Notes. Nothing contained in this Section 4.06 shall
prevent the Company or any Restricted Subsidiary from (1) creating, incurring,
assuming or suffering to exist any Liens otherwise permitted by Section 4.10 or
(2) restricting the sale or other disposition of property or assets of the
Company or any of its Restricted Subsidiaries that secure Indebtedness of the
Company or any of its Restricted Subsidiaries.

     SECTION 4.07. LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF
RESTRICTED SUBSIDIARIES.

     The Company will not sell, and will not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell, any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary; (ii) issuances of director's qualifying shares or sales
to foreign nationals of shares of Capital Stock of foreign Restricted
Subsidiaries, to the extent required by applicable law; (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 to such issuance or sale would have been permitted
to be made under Section 4.05 if made on the date of such issuance or sale; or
(iv) issuances or sales of Common Stock of a Restricted Subsidiary, provided
that the Company or such Restricted Subsidiary applies the Net Cash Proceeds, if
any, of any such sale in accordance with clause (A) or (B) of Section 4.11.


     SECTION 4.08. LIMITATION ON ISSUANCES OF GUARANTEES BY RESTRICTED
SUBSIDIARIES.

     The Company will not permit any Restricted Subsidiary, directly or
indirectly, to Guarantee any Indebtedness of the Company which is pari passu
with or subordinate in right of payment to the Notes ("Guaranteed
Indebtedness"), unless (i) such Restricted Subsidiary simultaneously executes
and delivers a supplemental indenture to this Indenture providing for a
Guarantee (a "Subsidiary Guarantee") of payment of the Notes by such Restricted
Subsidiary and (ii) such Restricted Subsidiary waives and will not in any manner
whatsoever claim or take the benefit or advantage of, any rights of
reimbursement, indemnity or subrogation or any other rights against the Company
or any other Restricted Subsidiary as a result of any payment by such Restricted
Subsidiary under its Subsidiary Guarantee; provided that this paragraph shall
not be


   55


                                       48


applicable to any Guarantee of any Restricted Subsidiary that existed at the
time such Person became a Restricted Subsidiary and was not Incurred in
connection with, or in contemplation of, such Person becoming a Restricted
Subsidiary. If the Guaranteed Indebtedness is (A) pari passu with the Notes,
then the Guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Subsidiary Guarantee or (B) subordinated to the Notes, then
the Guarantee of such Guaranteed Indebtedness shall be subordinated to the
Subsidiary Guarantee at least to the extent that the Guaranteed Indebtedness is
subordinated to the Notes.

     Notwithstanding the foregoing, any Subsidiary Guarantee by a Restricted
Subsidiary may provide by its terms that it shall be automatically and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company, of all of the Company's and each
Restricted Subsidiary's Capital Stock in, or all or substantially all the assets
of, such Restricted Subsidiary (which sale, exchange or transfer is not
prohibited by this Indenture) or (ii) the release or discharge of the Guarantee
which resulted in the creation of such Subsidiary Guarantee, except a discharge
or release by or as a result of payment under such Guarantee.

     SECTION 4.09. LIMITATIONS ON TRANSACTIONS WITH SHAREHOLDERS AND AFFILIATES.

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction 
(including, without limitation, the purchase, sale, lease or exchange of
property or assets, or the rendering of any service) with any holder (or any
Affiliate of such holder) of 10% or more of any class of Capital Stock of the
Company (calculated on a fully diluted basis) or with any Affiliate of the
Company or any Restricted Subsidiary, except upon fair and reasonable terms no
less favorable to the Company or such Restricted Subsidiary than could be
obtained, at the time of such transaction or, if such transaction is pursuant
to a written agreement, at the time of the execution of the agreement providing
therefor, in a comparable arm's-length transaction with a Person that is not
such a holder or an Affiliate.

     The foregoing limitation does not limit, and shall not apply to (i)
transactions (A) approved by a majority of the disinterested members of the
Board of Directors or (B) for which the Company or a Restricted Subsidiary
delivers to the Trustee a written opinion of a nationally recognized investment
banking firm stating that the transaction is fair to the Company or such
Restricted Subsidiary from a financial point of view; (ii) any transaction
solely between the Company and any of its Wholly Owned Restricted Subsidiaries
or solely between Wholly Owned Restricted Subsidiaries; (iii) the payment in
cash or securities of reasonable and customary regular fees to directors of the
Company who are not employees of the Company; (iv) any payments or other
transactions pursuant to any tax-sharing agreement between the Company and any
other Person with which the Company files a consolidated tax return or with
which the Company is part of a consolidated group for tax purposes; or (v) any
Restricted Payments not prohibited by Section 4.05. Notwithstanding the
foregoing, any 


   56


                                       49


transaction or series of related transactions covered by the first paragraph of
this Section 4.09 and not covered by clauses (ii) through (v) of this paragraph,
the aggregate amount of which exceeds $2 million in value, must be approved or
determined to be fair in the manner provided for in clause (i)(A) or (B) above.

     SECTION 4.10. LIMITATION ON LIENS.

     The Company and the Guarantors shall not Incur any Indebtedness secured by
a Lien ("Secured Indebtedness") which is not Senior Indebtedness unless
contemporaneously therewith effective provision is made to secure the Notes or
the Note Guarantee of such Guarantor, as the case may be, equally and ratably
with (or, if the Secured Indebtedness is subordinated in right of payment to the
Notes, prior to) such Secured Indebtedness for so long as such Secured
Indebtedness is secured by such Lien.

     The foregoing shall not apply to Liens (including extensions and renewals
thereof) upon real or personal property acquired after the Closing Date,
provided that (a) such Lien is created solely for the purpose of securing
Indebtedness Incurred, in accordance with Section 4.03, to finance the cost
(including the cost of design, development, acquisition, construction,
installation, improvement, transportation or integration) of the item of
property or assets subject thereto and such Lien is created prior to, at the
time of or within six months after the later of the acquisition, the completion
of construction or the commencement of full operation of such property, (b) the
principal amount of the Indebtedness secured by such Lien does not exceed 100%
of such cost and (c) any such Lien shall not extend to or cover any property or
assets other than such item of property or assets and any improvements on such
item.

     SECTION 4.11. LIMITATION ON ASSET SALES.

     The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless (i) the consideration received by the Company
or such Restricted Subsidiary is at least equal to the fair market value of the
assets sold or disposed of and (ii) at least 75% of the consideration received
consists of cash or Temporary Cash Investments; provided, however, that the
amount of any note or other securities received by the Company or any such
Restricted Subsidiary which are converted into cash within 180 days of such
Asset Sale shall be deemed to be cash for purposes of this provision. In the
event and to the extent that the Net Cash Proceeds received by the Company or
any of its Restricted Subsidiaries from one or more Asset Sales occurring on or
after the Closing Date in any period of 12 consecutive months exceed 10% of
Adjusted Consolidated Net Tangible Assets (determined as of the date closest to
the commencement of such 12-month period for which a consolidated balance sheet
of the Company and its Subsidiaries has been filed with the Commission pursuant
to Section 4.18), then the Company shall or shall cause the relevant Restricted
Subsidiary to (i) within twelve months after the date Net Cash Proceeds so
received exceed 10% of Adjusted Consolidated Net Tangible Assets (A) apply an
amount equal to such excess Net Cash Proceeds to permanently repay Senior
Indebtedness of the Company, or any Restricted


   57


                                       50


Subsidiary providing a Subsidiary Guarantee pursuant to Section 4.08 or
Indebtedness of any other Restricted Subsidiary, in each case owing to a Person
other than the Company or any of its Restricted Subsidiaries or (B) invest an
equal amount, or the amount not so applied pursuant to clause (A) (or enter into
a definitive agreement committing to so invest within 12 months after the date
of such agreement), in property or assets (other than current assets) of a
nature or type or that are used in a business (or in a company having property
and assets of a nature or type, or engaged in a business) similar or related to
the nature or type of the property and assets of, or the business of, the
Company and its Restricted Subsidiaries existing on the date of such investment
and (ii) apply (no later than the end of the 12-month period referred to in
clause (i)) such excess Net Cash Proceeds (to the extent not applied pursuant to
clause (i)) as provided in the following paragraph of this Section 4.11. The
amount of such excess Net Cash Proceeds required to be applied (or to be
committed to be applied) during such 12-month period as set forth in clause (i)
of the preceding sentence and not applied as so required by the end of such
period shall constitute "Excess Proceeds".

     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
Section 4.11 totals at least $10 million, the Company must commence, not later
than the fifteenth Business Day of such month, and consummate an Offer to
Purchase from the Holders on a pro rata basis an aggregate principal amount of
Notes equal to the Excess Proceeds on such date, at a purchase price equal to
100% of the principal amount of the Notes, plus, in each case, accrued interest
(if any) to the Payment Date.

     Upon the consummation of any Offer to Purchase pursuant to this Section
4.11, the amount of Excess Proceeds shall be reset to zero.

     Any transaction permitted under Article Five shall not be deemed an Asset
Sale for purposes of this Section 4.11.

     A Guarantor shall be discharged and released automatically from all of its
obligations under its Note Guarantee if all or substantially all of its assets
are sold or all of its Capital Stock is sold, in each case in a transaction in
compliance with this Section 4.11.

     SECTION 4.12. REPURCHASE OF NOTES UPON A CHANGE OF CONTROL.

     The Company shall commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding, at
a purchase price equal to 101% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Payment Date (subject to the right of Holders of
record on the relevant Regular Record Date that is prior to the Change of
Control to receive interest due on an Interest Payment Date).

   58


                                       51


     SECTION 4.13. EXISTENCE.

     Subject to Articles Four and Five of this Indenture, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its existence and the existence of each of its Restricted Subsidiaries in
accordance with the respective organizational documents of the Company and each
Restricted Subsidiary and the rights (whether pursuant to charter, partnership
certificate, agreement, statute or otherwise), licenses and franchises of the
Company and each Restricted Subsidiary; provided that the Company shall not be
required to preserve any such right, license or franchise, or the existence of
any Restricted Subsidiary, if the maintenance or preservation thereof is no
longer desirable in the conduct of the business of the Company and its
Restricted Subsidiaries taken as a whole.

     SECTION 4.14. PAYMENT OF TAXES AND OTHER CLAIMS.

     The Company will pay or discharge and shall cause each of its Subsidiaries
to pay or discharge, or cause to be paid or discharged, before the same shall
become delinquent (i) all material taxes, assessments and governmental charges
levied or imposed upon (a) the Company or any such Subsidiary, (b) the income or
profits of any such Subsidiary which is a corporation or (c) the property of the
Company or any such Subsidiary and (ii) all material lawful claims for labor,
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established.

     SECTION 4.15. MAINTENANCE OF PROPERTIES AND INSURANCE.

     The Company will cause all properties used or useful in the conduct of its
business or the business of any of its Restricted Subsidiaries to be maintained
and kept in good condition, repair and working order and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided
that nothing in this Section 4.15 shall prevent the Company or any Restricted
Subsidiary from discontinuing the use, operation or maintenance of any of such
properties or disposing of any of them, if such discontinuance or disposal is,
in the judgment of the Company, desirable in the conduct of the business of the
Company or such Restricted Subsidiary.

     The Company will provide or cause to be provided, for itself and its
Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties, including, but not limited to,
products liability insurance and public liability insurance, with reputable
insurers or with the government of the United States of America, or 


   59


                                       52


an agency or instrumentality thereof, in such amounts, with such deductibles and
by such methods as shall be customary for corporations similarly situated in the
industry in which the Company or any such Restricted Subsidiary, as the case may
be, is then conducting business.

     SECTION 4.16. NOTICE OF DEFAULTS.

     In the event that any Officer becomes aware of any Default or Event of
Default, the Company shall promptly deliver to the Trustee an Officers'
Certificate specifying such Default or Event of Default.

     SECTION 4.17. COMPLIANCE CERTIFICATES

     (a) The Company shall deliver to the Trustee, within 60 days after the end
of each fiscal quarter (120 days after the end of the last fiscal quarter of
each year), an Officers' Certificate stating whether or not the signers know of
any Default or Event of Default that occurred during such fiscal quarter. In the
case of the Officers' Certificate delivered within 120 days after the end of the
Company's fiscal year, such certificate shall contain a certification from the
principal executive officer, principal financial officer or principal accounting
officer of the Company that a review has been conducted of the activities of the
Company and its Restricted Subsidiaries and the Company's and its Restricted
Subsidiaries' performance under this Indenture and that the Company has complied
with all conditions and covenants under this Indenture. For purposes of this
Section 4.17, such compliance shall be determined without regard to any period
of grace or requirement of notice provided under this Indenture. If any of the
officers of the Company signing such certificate has knowledge of such a Default
or Event of Default, the certificate shall specify each such Default or Event of
Default and the nature and status thereof. The first certificate to be delivered
pursuant to this Section 4.17(a) shall be for the first fiscal quarter beginning
after the execution of this Indenture.

     (b) The Company shall deliver to the Trustee, within 120 days after the end
of each fiscal year, beginning with the fiscal year in which this Indenture was
executed, a certificate signed by the Company's independent certified public
accountants stating (i) that their audit examination has included a review of
the terms of this Indenture and the Notes as they relate to accounting matters,
(ii) that they have read the most recent Officers' Certificate delivered to the
Trustee pursuant to paragraph (a) of this Section 4.17 and (iii) whether, in
connection with their audit examination, anything came to their attention that
caused them to believe that the Company was not in compliance with any of the
terms, covenants, provisions or conditions of Article Four and Section 5.01 as
they pertain to accounting matters and, if any Default or Event of Default has
come to their attention, specifying the nature and period of existence thereof;
provided that such independent certified public accountants shall not be liable
in respect of such statement by reason of any failure to obtain knowledge of any
such Default or Event of Default that would not be disclosed in the course of an
audit examination conducted in accordance with generally accepted auditing
standards in effect at the date of such examination.

                                       53


     SECTION 4.18 COMMISSION REPORTS AND REPORTS TO HOLDERS.
     
Whether or not the Company is then required to file reports with the
Commission, the Company shall file with the Commission (if permitted) all such
reports and other information as it would be required to file with the
Commission by Sections 13(a) or 15(d) under the Exchange Act if it were subject
thereto. The Company shall supply the Trustee and each Holder or shall supply to
the Trustee for forwarding to each such Holder, without cost to such Holder,
copies of such reports and other information (whether or not so filed) within 15
days after the date it would have been required to file such reports or other
information with the Commission had it been subject to such Sections. The
Company also shall comply with the other provisions of TIA Section 314 (a).

     SECTION 4.19. WAIVER OF STAY, EXTENSION OR USURY LAWS.

     The Company covenants (to the extent that it may lawfully do so) that it
will 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 or any usury law or
other law that would prohibit or forgive the Company from paying all or any
portion of the principal of, premium, if any, or interest on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
that may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so) the Company hereby expressly waives all
benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.


                                  ARTICLE FIVE
                              SUCCESSOR CORPORATION

     SECTION 5.01. WHEN THE COMPANY MAY MERGE, ETC.

     The Company will not consolidate with, merge with or into, or sell, convey,
transfer, lease or otherwise dispose of all or substantially all of its property
and assets (as an entirety or substantially an entirety in one transaction or a
series of related transactions) to, any Person or permit any Person to merge
with or into the Company unless: (i) the Company shall be the continuing Person,
or the Person (if other than the Company) formed by such consolidation or into
which the Company is merged or that acquired or leased such property and assets
of the Company shall be a corporation organized and validly existing under the
laws of the United States of America or any jurisdiction thereof and shall
expressly assume, by a supplemental indenture, executed and delivered to the
Trustee, all of the obligations of the Company on all of the Notes and under
this Indenture; (ii) immediately after giving effect to such transaction, no
Default or Event of Default shall have occurred and be continuing; (iii)
immediately after giving effect to such transaction on a pro forma basis the
Company, or any Person becoming the successor obligor of the Notes, as the case
may be, could Incur at least $1.00 of Indebtedness under the first paragraph of
Section 4.03; provided that this clause 


   61


                                       54


(iii) shall not apply to a consolidation, merger or sale of assets of the
Company if all Liens and Indebtedness of the Company or any Person becoming the
successor obligor on the Notes, as the case may be, and its Restricted
Subsidiaries outstanding immediately after such transaction would, if Incurred
at such time, have been permitted to be Incurred (and all such Liens and
Indebtedness, other than Liens and Indebtedness of the Company and its
Restricted Subsidiaries outstanding immediately prior to the transaction, shall
be deemed to have been Incurred) for all purposes of this Indenture; and (iv)
the Company delivers to the Trustee an Officers' Certificate (attaching the
arithmetic computations to demonstrate compliance with clause (iii)) and an
Opinion of Counsel, in each case stating that such consolidation, merger or
transfer and such supplemental indenture complies with this provision and that
all conditions precedent provided for herein relating to such transaction have
been complied with; provided, however, that clauses (iii) and (iv) above do not
apply if, in the good faith determination of the Board of Directors of the
Company, whose determination shall be evidenced by a Board Resolution, the
principal purpose of such transaction is to change the state of incorporation of
the Company; and provided further that any such transaction shall not have as
one of its purposes the evasion of the foregoing limitations.


     Notwithstanding the foregoing, (i) any Restricted Subsidiary of the Company
may consolidate with, merge into or transfer all or part of its properties and
assets to the Company and (ii) the Company may merge with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction to realize tax or other similar benefits.

     Each Guarantor will not consolidate with, merge with or into, or sell,
convey, transfer, lease or otherwise dispose of all or substantially all of its
property and assets (as an entirety or substantially an entirety in one
transaction or a series of related transactions) to, any Person (other than the
Company or another Guarantor) or permit any Person to merge with or into it
unless: (i) such Guarantor shall be the continuing Person, or (ii) the Person
(if other than such Guarantor) formed by such consolidation or into which such
Guarantor is merged or that acquired or leased such property and assets of such
Guarantor shall be a corporation organized and validly existing under the laws
of the United States of America or any jurisdiction thereof and shall expressly
assume, by a supplemental indenture, executed and delivered to the Trustee, all
of the obligations of such Guarantor's Note Guarantee. Notwithstanding the
foregoing sentence, a Guarantor shall be discharged and released from all of its
obligations under its Note Guarantee if all or substantially all of its assets
are sold, or all of its Capital Stock is sold, in each case in a transaction in
compliance with Section 4.11.

     SECTION 5.02. SUCCESSOR SUBSTITUTED.

     Upon any consolidation or merger, or any sale, conveyance, transfer, lease
or other disposition of all or substantially all of the property and assets of
the Company in accordance with Section 5.01, the successor Person formed by such
consolidation or into which the Company is merged or to which such sale,
conveyance, transfer, lease or other disposition is made shall succeed to, and
be substituted for, and may exercise every right and power of, the Company under
this 


   62


                                       55


Indenture with the same effect as if such successor Person had been named as the
Company herein; provided that the Company shall not be released from its
obligation to pay the principal of, premium, if any, or interest on the Notes in
the case of a lease of all or substantially all of its property and assets.


                                   ARTICLE SIX
                              DEFAULT AND REMEDIES

     SECTION 6.01. EVENTS OF DEFAULT.

     Any of the following events shall constitute an "EVENT OF DEFAULT"
hereunder:

     (a) default in the payment of principal of (or premium, if any, on) any
Note when the same becomes due and payable at Stated Maturity, upon
acceleration, redemption or otherwise;

     (b) default in the payment of interest on any Note when the same becomes
due and payable, and such default continues for a period of 30 days whether or
not such payment is prohibited by Article Ten;

     (c) default in the performance or breach of Article Five or the failure to
comply for 30 days after notice of its obligation to make an Offer to Purchase
in accordance with Section 4.11 or Section 4.12;

     (d) the Company defaults in the performance of or breaches any other
covenant or agreement of the Company in this Indenture or under the Notes (other
than a default specified in clause (a), (b) or (c) above) and such default or
breach continues for a period of 60 consecutive days after written notice by the
Trustee or the Holders of 25% or more in aggregate principal amount of the
Notes;

     (e) there occurs with respect to any issue or issues of Indebtedness of the
Company or any Significant Subsidiary having an outstanding principal amount of
$10 million or more in the aggregate for all such issues of all such Persons,
whether such Indebtedness now exists or shall hereafter be created, (i) an event
of default that has caused the holder thereof to declare such Indebtedness to be
due and payable prior to its Stated Maturity and such Indebtedness has not been
discharged in full or such acceleration has not been rescinded or annulled
within 60 days of such acceleration and/or (ii) the failure to make a principal
payment at the final (but not any interim) fixed maturity and such defaulted
payment shall not have been made, waived or extended within the applicable grace
period related to any such payment default;


     (f) any final judgment or order (not covered by insurance) for the payment
of 


   63


                                       56


money in excess of $10 million in the aggregate for all such final judgments or
orders against all such Persons (treating any deductibles, self-insurance or
retention as not so covered) shall be rendered against the Company or any
Significant Subsidiary and shall not be paid or discharged, and there shall be
any period of 60 consecutive days following entry of the final judgment or order
that causes the aggregate amount for all such final judgments or orders
outstanding and not paid or discharged against all such Persons to exceed $10
million during which a stay of enforcement of such final judgment or order, by
reason of a pending appeal or otherwise, shall not be in effect;

     (g) a court having jurisdiction in the premises enters a decree or order
for (A) relief in respect of the Company or any Guarantor that would be a
Significant Subsidiary if the references to 10% in the definition of Significant
Subsidiary were 20% instead of 10% (a "Significant Guarantor") or any
Significant Subsidiary in an involuntary case under any applicable bankruptcy,
insolvency or other similar law now or hereafter in effect, (B) appointment of a
receiver, liquidator, assignee, custodian, trustee, sequestrator or similar
official of the Company or any Significant Guarantor or any Significant
Subsidiary or for all or substantially all of the property and assets of the
Company or any Significant Guarantor or any Significant Subsidiary or (C) the
winding up or liquidation of the affairs of the Company or any Significant
Guarantor or any Significant Subsidiary and, in each case, such decree or order
shall remain unstayed and in effect for a period of 60 consecutive days;

     (h) the Company or any Significant Guarantor or any Significant Subsidiary
(A) commences a voluntary case under any applicable bankruptcy, insolvency or
other similar law now or hereafter in effect, or consents to the entry of an
order for relief in an involuntary case under any such law, (B) consents to the
appointment of or taking possession by a receiver, liquidator, assignee,

Significant Guarantor or any Significant Subsidiary or for all or substantially
all of the property and assets of the Company or any Significant Guarantor or
any Significant Subsidiary or (C) effects any general assignment for the benefit
of creditors; or

     (i) the Company or any Guarantor disclaims any Note Guarantee or asserts
that any Note Guarantee is not binding on any Guarantor.

     SECTION 6.02. ACCELERATION.

     If an Event of Default (other than an Event of Default specified in clause
(g) or (h) of Section 6.01 that occurs with respect to the Company or any
Significant Guarantor or any Significant Subsidiary) occurs and is continuing
under this Indenture, the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes, then outstanding, by written notice to the
Company (and to the Trustee if such notice is given by the Holders), may, and
the Trustee at the request of such Holders shall, declare the principal of,
premium, if any, and accrued interest on the Notes to be immediately due and
payable. Upon a declaration of acceleration, such principal, premium, if any,
and accrued interest shall be immediately due and payable; provided, however,
that so long as the Credit Facility is in effect, such declaration shall not
become 


   64


                                       57


effective until the earlier of (A) five Business Days after delivery of such
notice to the representative of the Credit Facility and (B) the acceleration of
any Indebtedness under the Credit Facility. In the event of a declaration of
acceleration because an Event of Default set forth in clause (e) of Section 6.01
has occurred and is continuing, such declaration of acceleration shall be
automatically rescinded and annulled if the event of default triggering such
Event of Default pursuant to clause (e) shall be remedied or cured by the
Company or the relevant Significant Guarantor or the relevant Significant
Subsidiary or waived by the holders of the relevant Indebtedness within 60 days
after the declaration of acceleration with respect thereto. If an Event of
Default specified in clause (g) or (h) of Section 6.01 occurs with respect to
the Company or any Significant Guarantor or Significant Subsidiary, the
principal of, premium, if any, and accrued interest on the Notes then
outstanding shall ipso facto become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder.


     At any time after such declaration of acceleration, but before a judgment
or decree for the payment of the money due has been obtained by the Trustee, the
Holders of at least a majority in principal amount of the outstanding Notes by
written notice to the Company and to the Trustee, may waive all past Defaults
and rescind and annul a declaration of acceleration and its consequences if (a)
the Company has paid or deposited with the Trustee a sum sufficient to pay (i)
all sums paid or advanced by the Trustee hereunder and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, (ii) all overdue interest on all Notes, (iii) the principal of and
premium, if any, on the Notes that have become due otherwise than by such
declaration or occurrence of acceleration and interest thereon at the rate
prescribed therefor by such Notes, and (iv) to the extent that the payment of
such interest is lawful, interest upon overdue interest, if any, at the rate
prescribed therefor, by such Notes, (b) existing Events of Default, other than
the non-payment of the principal of, premium, if any, and accrued interest on
the Notes that have become due solely by such declaration of acceleration, have
been cured or waived and (c) the rescission would not conflict with any judgment
or decree of a court of competent jurisdiction.

     SECTION 6.03. OTHER REMEDIES.

     If an Event of Default occurs and is continuing, the Trustee may, and at
the direction of the Holders of at least a majority in principal amount of the
outstanding Notes shall, pursue any available remedy by proceeding at law or in
equity to collect the payment of principal of, premium, if any, or interest on
the Notes or to enforce the performance of any provision of the Notes or this
Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding.


     SECTION 6.04. WAIVER OF PAST DEFAULTS.

     Subject to Sections 6.02, 6.07 and 9.02, the Holders of at least a majority
in principal amount of the outstanding Notes, by notice to the Trustee, may
waive an existing Default or Event of 


   65


                                       58


Default and its consequences, except a Default in the payment of principal of,
premium, if any, or interest on any Note as specified in clause (a) or (b) of
Section 6.01 or in respect of a covenant or provision of this Indenture which
cannot be modified or amended without the consent of the Holder of each
outstanding Note affected. Upon any such waiver, such Default shall cease to
exist, and any Event of Default arising therefrom shall be deemed to have been
cured, for every purpose of this Indenture; but no such waiver shall extend to
any subsequent or other Default or Event of Default or impair any right
consequent thereto.

     SECTION 6.05. CONTROL BY MAJORITY.

     The Holders of at least a majority in aggregate principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee; provided that, the Trustee may refuse to follow
any direction that conflicts with law or this Indenture, that may involve the
Trustee in personal liability, or that the Trustee determines in good faith may
be unduly prejudicial to the rights of Holders of Notes not joining in the
giving of such direction; and provided further that the Trustee may take any
other action it deems proper that is not inconsistent with any such direction
received from Holders of Notes.

     SECTION 6.06. LIMITATION ON SUITS.

     A Holder may not institute any proceeding, judicial or otherwise, with
respect to this Indenture or the Notes, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless:

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

          (ii) the Holders of at least 25% in aggregate principal amount of
     outstanding Notes shall have made a written request to the Trustee to
     pursue such remedy;

          (iii) such Holder or Holders offer the Trustee indemnity reasonably
     satisfactory to the Trustee against any costs, liability or expense;

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

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

     For purposes of Section 6.05 and this Section 6.06, the Trustee shall
comply with TIA Section 316(a) in making any determination of whether the
Holders of the required aggregate principal amount of outstanding Notes have
concurred in any request or direction of the 


   66


                                       59


Trustee to pursue any remedy available to the Trustee or the Holders with
respect to this Indenture or the Notes or otherwise under the law.

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

     SECTION 6.07. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

     Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of the principal of, premium, if any, or
interest on, such Note or to bring suit for the enforcement of any such payment,
on or after the due date expressed in the Notes, shall not be impaired or
affected without the consent of such Holder.

     SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

     If an Event of Default in payment of principal, premium or interest
specified in clause (a), (b) or (c) of Section 6.01 occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor of the Notes for the whole amount
of principal, premium, if any, and accrued interest remaining unpaid, together
with interest on overdue principal, premium, if any, and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate specified in the Notes, and such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

     SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 7.07) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor of the Notes), its
creditors or its property and shall be entitled and empowered to collect and
receive any monies, securities or other property payable or deliverable upon
conversion or exchange of the Notes or upon any such claims and to distribute
the same, and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee and, in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07. Nothing
herein contained shall be deemed to empower the Trustee to authorize or consent
to, or accept or adopt on behalf of any Holder, any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any
Holder thereof, or to authorize the Trustee to vote in respect of the claim of
any Holder in 


   67


                                       60

any such proceeding.

     SECTION 6.10. PRIORITIES.

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


          First: to the Trustee for all amounts due under Section 7.07, subject
     only to the written disapproval of any representative of the holders of the
     Senior Indebtedness as to amounts reasonably determined by them or it to be
     excessive and unreasonable;

          Second: to the holders of Senior Indebtedness, as and to the extent
     required by Article Ten;

          Third: to the Trustee as to all remaining amounts due it under Section
     7.07 and not paid pursuant to priority First, above;

          Fourth: to Holders for amounts then due and unpaid for principal of,
     premium, if any, and interest on the Notes in respect of which or for the
     benefit of which such money has been collected, ratably, without preference
     or priority of any kind, according to the amounts due and payable on such
     Notes for principal, premium, if any, and interest, respectively; and

          Fifth: to the Company or any other obligors of the Notes, as their
     interests may appear, or as a court of competent jurisdiction may direct.

          The Trustee, upon prior written notice to the Company, may fix a
     record date and payment date for any payment to Holders pursuant to this
     Section 6.10.

     SECTION 6.11 UNDERTAKING FOR COSTS.

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

     SECTION 6.12. RESTORATION OF RIGHTS AND REMEDIES.

     If the Trustee or any Holder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then, and in every such case, subject to any determination in
such proceeding, the Company, 


   68


                                       61

the Trustee and the Holders shall be restored severally and respectively to
their former positions hereunder and thereafter all rights and remedies of the
Company, Trustee and the Holders shall continue as though no such proceeding had
been instituted.

     SECTION 6.13. RIGHTS AND REMEDIES CUMULATIVE.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or wrongfully taken Notes in Section 2.09, no right
or remedy herein conferred upon or reserved to the Trustee or to the Holders is
intended to be exclusive of any other right or remedy, and every right and
remedy shall, to the extent permitted by law, be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law
or in equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

     SECTION 6.14. DELAY OR OMISSION NOT WAIVER.

     No delay or omission of the Trustee or of any Holder to exercise any right
or remedy accruing upon any Event of Default shall impair any such right or
remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article Six or by law to the
Trustee or to the Holders may be exercised from time to time, and as often as
may be deemed expedient, by the Trustee or by the Holders, as the case may be.


                                  ARTICLE SEVEN
                                     TRUSTEE

     SECTION 7.01. GENERAL.

     The duties and responsibilities of the Trustee shall be as provided by the
TIA and as set forth herein. Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any 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 for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not herein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Article Seven.

     SECTION 7.02. CERTAIN RIGHTS OF TRUSTEE.

     Subject to TIA Sections 315(a) through (d):

          (i) the Trustee may rely, and shall be protected in acting or
     refraining from acting, upon any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, debenture, note, other evidence of 


   69


                                       62


     indebtedness or other paper or document believed by it to be genuine and to
     have been signed or presented by the proper person;

          (ii) before the Trustee acts or refrains from acting, it may require
     an Officers' Certificate or an Opinion of Counsel, which shall conform to
     Section 10.04. The Trustee shall not be liable for any action it takes or
     omits to take in good faith in reliance on such certificate or opinion;

          (iii) the Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any attorney or
     agent appointed with due care by it hereunder;

          (iv) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by this Indenture at the request or direction
     of any of the Holders, unless such Holders shall have offered to the
     Trustee reasonable security or indemnity against the costs, expenses and
     liabilities that might be incurred by it in compliance with such request or
     direction;

          (v) the Trustee shall not be liable for any action it takes or omits
     to take in good faith that it believes to be authorized or within its
     rights or powers, provided that the Trustee's conduct does not constitute
     negligence or bad faith;

          (vi) whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon an Officers' Certificate; and

          (vii) the 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, direction, consent, order,
     bond, debenture, note, other evidence of indebtedness or other paper or
     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the
     Trustee shall determine to make such further inquiry or investigation, it
     shall be entitled to examine the books, records and premises of the Company
     personally or by agent or attorney.

     SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee, in its individual or any other capacity, may become the owner
or pledgee of Notes and may otherwise deal with the Company or its Affiliates
with the same rights it would have if it were not the Trustee. Any Agent may do
the same with like rights. However, the Trustee is subject to TIA Sections
310(b) and 311.


   70


                                       63

     SECTION 7.04. TRUSTEE'S DISCLAIMER.

     The Trustee (i) makes no representation as to the validity or adequacy of
this Indenture or the Notes, (ii) shall not be accountable for the Company's use
or application of the proceeds from the Notes and (iii) shall not be responsible
for any statement in the Notes other than its certificate of authentication.

     SECTION 7.05. NOTICE OF DEFAULT.

     If any Default or any Event of Default occurs and is continuing and if such
Default or Event of Default is known to the Trustee, the Trustee shall mail to
each Holder in the manner and to the extent provided in TIA Section 313(c)
notice of the Default or Event of Default within 45 days after it occurs, unless
such Default or Event of Default has been cured; provided, however, that, except
in the case of a default in the payment of the principal of, premium, if any, or
interest on any Note, the Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the Holders.

     SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS.

     Within 60 days after each May 15, beginning with May 15, 1999, the Trustee
shall mail to each Holder as provided in TIA Section 313(c) a brief report dated
as of such May 15, if required by TIA Section 313(a).

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

     SECTION 7.07. COMPENSATION AND INDEMNITY.

     The Company shall pay to the Trustee such compensation as shall be agreed
upon in writing for its services hereunder. The compensation of the Trustee
shall not be limited by any law on compensation of a trustee of an express
trust. The Company shall reimburse the Trustee upon request for all reasonable
disbursements, expenses and advances incurred or made by the Trustee without
negligence or bad faith on its part. Such expenses shall include the reasonable
compensation and expenses of the Trustee's agents and counsel.

     The Company shall indemnify the Trustee for, and hold it harmless against,
any loss or liability or expense incurred by it without negligence or bad faith
on its part in connection with the acceptance or administration of this
Indenture and its duties under this Indenture and the Notes, including the costs
and expenses of defending itself against any claim or liability and of complying
with any process served upon it or any of its officers in connection with the
exercise or performance of any of its powers or duties under this Indenture and
the Notes. The Trustee shall notify the Company promptly of any claim for which
it may seek indemnity. 


   71


                                       64


Failure by the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder, unless the Company is materially prejudiced thereby.
The Company shall defend the claim and the Trustee shall cooperate in the
defense. Unless otherwise set forth herein, the Trustee may have separate
counsel and the Company shall pay the reasonable fees and expenses of such
counsel. The Company need not pay for any settlement made without its consent,
which consent shall not be unreasonably withheld.

     To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a lien prior to the Notes on all money or property held or
collected by the Trustee, in its capacity as Trustee, except money or property
held in trust to pay principal of, premium, if any, and interest on particular
Notes.

     If the Trustee incurs expenses or renders services after the occurrence of
an Event of Default specified in clause (g) or (h) of Section 6.01, the expenses
and the compensation for the services will be intended to constitute expenses of
administration under Title 11 of the United States Bankruptcy Code or any
applicable federal or state law for the relief of debtors.

     The provisions of this Section 7.07 shall survive the termination of this
Indenture.

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

     SECTION 7.08. REPLACEMENT OF TRUSTEE.

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

     The Trustee may resign at any time by so notifying the Company in writing
at least 30 days prior to the date of the proposed resignation. The Holders of a
majority in principal amount of the outstanding Notes may remove the Trustee by
so notifying the Trustee in writing and may appoint a successor Trustee with the
consent of the Company. The Company may remove the Trustee if: (i) the Trustee
is no longer eligible under Section 7.10; (ii) the Trustee is adjudged a
bankrupt or an insolvent; (iii) a receiver or other public officer takes charge
of the Trustee or its property; or (iv) the Trustee becomes incapable of acting.

     If the Trustee resigns or is removed, or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in principal amount of the outstanding Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company. If
the successor Trustee does not deliver its written acceptance required by the
next succeeding paragraph of this Section 7.08 within 30 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Company or the Holders
of a majority in 


   72


                                       65


principal amount of the outstanding Notes may, at the expense of the Company,
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Immediately after the delivery of
such written acceptance, subject to the lien provided in Section 7.07, (i) the
retiring Trustee shall transfer all property held by it as Trustee to the
successor Trustee, (ii) the resignation or removal of the retiring Trustee shall
become effective and (iii) the successor Trustee shall have all the rights,
powers and duties of the Trustee under this Indenture. A successor Trustee shall
mail notice of its succession to each Holder. No successor Trustee shall accept
its appointment unless at the time of such acceptance such successor Trustee
shall be qualified and eligible under this Article.

     If the Trustee is no longer eligible under Section 7.10 or shall fail to
comply with TIA Section 310(b), any Holder who satisfies the requirements of TIA
Section 310(b) may petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor Trustee. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section 7.08, the Trustee shall resign immediately in the manner and with the
effect provided in this Section.

the Company's obligation under Section 7.07 shall continue for the benefit of
the retiring Trustee.

     SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee consolidates with, merges or converts into, or transfers all
or substantially all of its corporate trust business to, another corporation or
national banking association, the resulting, surviving or transferee corporation
or national banking association without any further act shall be the successor
Trustee with the same effect as if the successor Trustee had been named as the
Trustee herein, provided such corporation shall be otherwise qualified and
eligible under this Article.

     SECTION 7.10. ELIGIBILITY.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA Section 310(a)(1). The Trustee shall have a combined capital and surplus
of at least $25 million as set forth in its most recent published annual report
of condition that is subject to the requirements of applicable Federal or state
supervising or examining authority. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall

     SECTION 7.11. MONEY HELD IN TRUST.

     The Trustee shall not be liable for interest on any money received by it

                                  ARTICLE EIGHT
                             DISCHARGE OF INDENTURE
     
     SECTION 8.01. TERMINATION OF COMPANY'S OBLIGATIONS.

     Except as otherwise provided in this Section 8.01, the Company may
terminate its obligations under the Notes and this Indenture if:

          (i) all Notes previously authenticated and delivered (other than
     destroyed, lost or stolen Notes that have been replaced or Notes that are
     paid pursuant to Section 4.01 or Notes for whose payment money or
     securities have theretofore been held in trust and thereafter repaid to the
     Company, as provided in Section 8.05) have been delivered to the Trustee
     for cancellation and the Company has paid all sums payable by it hereunder;
     or


          (ii) (A) the Notes mature within one year or all of them are to be
     called for redemption within one year under arrangements satisfactory to
     the Trustee for giving the notice of redemption, (B) the Company
     irrevocably deposits in trust with the Trustee during such one-year period,
     under the terms of an irrevocable trust agreement in form and substance
     satisfactory to the Trustee, as trust funds solely for the benefit of the
     Holders for that purpose, money or Government Securities sufficient (in the
     opinion of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee),
     without consideration of any reinvestment of any interest thereon, to pay
     principal, premium, if, any, and interest on the Notes to maturity or
     redemption, as the case may be, and to pay all other sums payable by it
     hereunder, (C) no Default or Event of Default with respect to the Notes
     shall have occurred and be continuing on the date of such deposit, (D) such
     deposit will not result in a breach or violation of, or constitute a
     default under, this Indenture or any other agreement or instrument to which

     Company has delivered to the Trustee an Officers' Certificate and an
     Opinion of Counsel, in each case stating that all conditions precedent
     provided for herein relating to the satisfaction and discharge of this
     Indenture have been complied with.

Section 7.07 


   74


                                       67


shall survive. With respect to the foregoing clause (ii), the Company's
obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 2.14,
4.01, 4.02, 7.07, 7.08, 8.04, 8.05 and 8.06 shall survive until the Notes are no
longer outstanding. Thereafter, only the Company's obligations in Sections 7.07,
8.04, 8.05 and 8.06 and Article Ten (with respect to payments in respect of
Senior Subordinated Obligations other than with the assets held in trust as
described in clause (ii) above) shall survive. After any such irrevocable
deposit, the Trustee upon request shall acknowledge in writing the discharge of
the Company's obligations under the Notes and this Indenture except for those
surviving obligations specified above.

     SECTION 8.02. DEFEASANCE AND DISCHARGE OF INDENTURE.

     The Company will be deemed to have paid and will be discharged from any and
all obligations in respect of the Notes on the 123rd day after the date of the
deposit referred to in clause (A) of this Section 8.02, and the provisions of
this Indenture will no longer be in effect with respect to the Notes, and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same if:

          (A) with reference to this Section 8.02, the Company has irrevocably
     deposited or caused to be irrevocably deposited with the Trustee (or
     another trustee satisfying the requirements of Section 7.10) and conveyed
     all right, title and interest to the Trustee for the benefit of the
     Holders, under the terms of an irrevocable trust agreement in form and
     substance satisfactory to the Trustee as trust funds in trust, specifically
     pledged to the Trustee for the benefit of the Holders as security for
     payment of the principal of, premium, if any, and interest, if any, on the
     Notes, and dedicated solely to, the benefit of the Holders, in and to (1)
     money in an amount, (2) Government Securities that, through the payment of
     interest, premium, if any, and principal in respect thereof in accordance
     with their terms, will provide, not later than one day before the due date
     of any payment referred to in this clause (A), money in an amount or (3) a
     combination thereof in an amount sufficient, in the opinion of a nationally
     recognized firm of independent public accountants expressed in a written
     certification thereof delivered to the Trustee, to pay and discharge,
     without consideration of the reinvestment of such interest and after
     payment of all federal, state and local taxes or other charges and
     assessments in respect thereof payable by the Trustee, the principal of,
     premium, if any, and interest on the outstanding Notes on the Stated
     Maturity of such principal or interest; provided that the Trustee shall
     have been irrevocably instructed to apply such money or the proceeds of
     such U.S. Government Securities to the payment of such principal, premium,
     if any, and interest with respect to the Notes;

          (B) the Company has delivered to the Trustee (1) either (x) an Opinion
     of Counsel to the effect that Holders will not recognize income, gain or
     loss for federal income tax purposes as a result of the Company's exercise
     of its option under this Section 8.02 and will be subject to federal income
     tax on the same amount and in the 


   75


                                       68


     same manner and at the same times as would have been the case if such
     option had not been exercised, which Opinion of Counsel shall be based upon
     (and accompanied by a copy of) a ruling of the Internal Revenue Service to
     the same effect unless there has been a change in applicable federal income
     tax law after the Closing Date such that a ruling is no longer required or
     (y) a ruling directed to the Trustee received from the Internal Revenue
     Service to the same effect as the aforementioned Opinion of Counsel and (2)
     an Opinion of Counsel to the effect that the creation of the defeasance
     trust does not violate the Investment Company Act of 1940 and that after
     the passage of 123 days following the deposit (except, with respect to any
     trust funds for the account of any Holder who may be deemed to be an
     "insider" for purposes of the United States Bankruptcy Code, after one year
     following the deposit), the trust funds will not be subject to the effect
     of Section 547 of the United States Bankruptcy Code or Section 15 of the
     New York Debtor and Creditor Law in a case commenced by or against the
     Company under either such statute, and either (i) the trust funds will no
     longer remain the property of the Company (and therefore will not be
     subject to the effect of any applicable bankruptcy, insolvency,
     reorganization or similar laws affecting creditors' rights generally) or
     (II) if a court were to rule under any such law in any case or proceeding
     that the trust funds remained property of the Company, (a) assuming such
     trust funds remained in the possession of the Trustee prior to such court
     ruling to the extent not paid to the Holders, the Trustee will hold, for
     the benefit of the Holders, a valid and perfected security interest in such
     trust funds that is not avoidable in bankruptcy or otherwise except for the
     effect of Section 552(b) of the United States Bankruptcy Code on interest
     on the trust funds accruing after the commencement of a case under such
     statute and (b) the Holders will be entitled to receive adequate protection
     of their interests in such trust funds if such trust funds are used in such
     case or proceeding;


          (C) immediately after giving effect to such deposit, on a pro forma
     basis, no Default or Event of Default shall have occurred and be continuing
     on the date of such deposit or during the period ending on the 123rd day
     after such date of such deposit, and such deposit shall not result in a
     breach or violation of, or constitute a Default under, this Indenture or
     any other agreement or instrument to which the Company or any of its
     Subsidiaries is a party or by which the Company or any of its Subsidiaries
     is bound and is permitted by Article Ten;

          (D) if the Notes are then listed on a national securities exchange,
     the Company has delivered to the Trustee an Opinion of Counsel to the
     effect that the Notes will not be delisted as a result of such deposit,
     defeasance and discharge; and

          (E) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the defeasance contemplated by
     this Section 8.02 have been complied with.


   76


                                       69


     Notwithstanding the foregoing, prior to the end of the 123-day (or one
year) period referred to in clause (B)(2) of this Section 8.02, none of the
Company's obligations under this Indenture shall be discharged. Subsequent to
the end of such 123-day (or one year) period with respect to this Section 8.02,
the Company's obligations in Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08,
2.09, 2.14, 4.01, 4.02, 8.04, 8.05, 8.06 and the rights, powers, trusts, duties
and immunities of the Trustee hereunder and Article Ten (with respect to
payments in respect of Senior Subordinated Obligations other than with the
assets held in trust as described in this Section 8.02) shall survive until the
Notes are no longer outstanding. Thereafter, only the Company's obligations in
Sections 7.07, 8.04, 8.05 and 8.06 shall survive. If and when a ruling from the
Internal Revenue Service or an Opinion of Counsel referred to in clause (B)(1)
of this Section 8.02 is able to be provided specifically without regard to, and
not in reliance upon, the continuance of the Company's obligations under Section
4.01, then the Company's obligations under such Section 4.01 shall cease upon
delivery to the Trustee of such ruling or Opinion of Counsel and compliance with
the other conditions precedent provided for herein relating to the defeasance
contemplated by this Section 8.02.

     After any such irrevocable deposit, the Trustee upon request shall
acknowledge in writing the discharge of the Company's obligations under the
Notes and this Indenture except for those surviving obligations in the
immediately preceding paragraph.

     SECTION 8.03. DEFEASANCE OF CERTAIN OBLIGATIONS.

     The Company may omit to comply with any term, provision or condition set
forth in clauses (iii) and (iv) of Section 5.01 and Sections 4.03 through 4.11
and clause (c) of Section 6.01 with respect to clauses (iii) and (iv) of Section
5.01, clause (d) of Section 6.01 with respect to Sections 4.01, 4.02 and 4.12
through 4.19 and clauses (e) and (f) of Section 6.01 shall be deemed not to be
Events of Default and Article Ten shall not apply to the money and/or U.S.
Government Securities held by the trust referred to in clause (i) below, in each
case with respect to the outstanding Notes if:


          (i) with reference to this Section 8.03, the Company has irrevocably
     deposited or caused to be irrevocably deposited with the Trustee (or
     another trustee satisfying the requirements of Section 7.10) and conveyed
     all right, title and interest to the Trustee for the benefit of the
     Holders, under the terms of an irrevocable trust agreement in form and
     substance satisfactory to the Trustee as trust funds in trust, specifically
     pledged to the Trustee for the benefit of the Holders as security for
     payment of the principal of, premium, if any, and interest, if any, on the
     Notes, and dedicated solely to, the benefit of the Holders, in and to (A)
     money in an amount, (B) Government Securities that, through the payment of
     interest, premium, if any, and principal in respect thereof in accordance
     with their terms, will provide, not later than 


   77


                                       70


     one day before the due date of any payment referred to in this clause (i),
     money in an amount or (C) a combination thereof in an amount sufficient, in
     the opinion of a nationally recognized firm of independent public
     accountants expressed in a written certification thereof delivered to the
     Trustee, to pay and discharge, without consideration of the reinvestment of
     such interest and after payment of all federal, state and local taxes or
     other charges and assessments in respect thereof payable by the Trustee,
     the principal of, premium, if any, and interest on the outstanding Notes on
     the Stated Maturity of such principal or interest; provided that the
     Trustee shall have been irrevocably instructed to apply such money or the
     proceeds of such U.S. Government Securities to the payment of such
     principal, premium, if any, and interest with respect to the Notes;

          (ii) the Company has delivered to the Trustee an Opinion of Counsel to
     the effect that (A) the creation of the defeasance trust does not violate
     the Investment Company Act of 1940, (B) after the passage of 123 days
     following the deposit (except, with respect to any trust funds for the
     account of any Holder who may be deemed to be an "insider" for purposes of
     the United States Bankruptcy Code, after one year following the deposit),
     the trust funds will not be subject to the effect of Section 547 of the
     United States Bankruptcy Code or Section 15 of the New York Debtor and
     Creditor Law in a case commenced by or against the Company under either
     such statute, and either (1) the trust funds will no longer remain the
     property of the Company (and therefore will not be subject to the effect of
     any applicable bankruptcy, insolvency, reorganization or similar laws
     affecting creditors' rights generally) or (2) if a court were to rule under
     any such law in any case or proceeding that the trust funds remained
     property of the Company, (x) assuming such trust funds remained in the
     possession of the Trustee prior to such court ruling to the extent not paid
     to the Holders, the Trustee will hold, for the benefit of the Holders, a
     valid and perfected security interest in such trust funds that is not
     avoidable in bankruptcy or otherwise (except for the effect of Section
     552(b) of the United States Bankruptcy Code on interest on the trust funds
     accruing after the commencement of a case under such statute) and (y) the
     Holders will be entitled to receive adequate protection of their interests
     in such trust funds if such trust funds are used in such case or
     proceeding, (C) the Holders will not recognize income, gain or loss for
     federal income tax purposes as a result of such deposit and defeasance of
     certain covenants and Events of Default and will be subject to federal
     income tax on the same amount and in the same manner and at the same times
     as would have been the case if such deposit and defeasance had not occurred
     and (D) the Trustee, for the benefit of the Holders, has a valid
     first-priority security interest in the trust funds;

          (iii) immediately after giving effect to such deposit on a pro forma
     basis, no Default or Event of Default shall have occurred and be continuing
     on the date of such deposit or during the period ending on the 123rd day
     after such date of such deposit, 


   78


                                       71


     and such deposit shall not result in a breach or violation of, or
     constitute a default under, this Indenture or any other agreement or
     instrument to which the Company or any of its Subsidiaries is a party or by
     which the Company or any of its Subsidiaries is bound and is permitted by
     Article Ten;

          (iv) if the Notes are then listed on a national securities exchange,
     the Company has delivered to the Trustee an Opinion of Counsel to the
     effect that the Notes will not be delisted as a result of such deposit,
     defeasance and discharge; and

          (v) the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, in each case stating that all conditions
     precedent provided for herein relating to the defeasance contemplated by
     this Section 8.03 have been complied with.

     SECTION 8.04. APPLICATION OF TRUST MONEY.

     Subject to Section 8.06, the Trustee or Paying Agent shall hold in trust
money or Government Securities deposited with it pursuant to Section 8.01, 8.02
or 8.03, as the case may be, and shall apply the deposited money and the money
from Government Securities in accordance with the Notes and this Indenture to
the payment of principal of, premium, if any, and interest on the Notes; but
such money need not be segregated from other funds except to the extent required
by law.

     SECTION 8.05. REPAYMENT TO COMPANY.

     Subject to Sections 7.07, 8.01, 8.02 and 8.03, the Trustee and the Paying
Agent shall promptly pay to the Company upon request set forth in an Officers'
Certificate any excess money held by them at any time and thereupon shall be
relieved from all liability with respect to such money. The Trustee and the
Paying Agent shall pay to the Company upon request any money held by them for
the payment of principal, premium, if any, or interest that remains unclaimed
for two years; provided that the Trustee or Paying Agent before being required
to make any payment may cause to be published at the expense of the Company once
in a newspaper of general circulation in The City of New York and, in the event
the Notes are listed on the Luxembourg Stock Exchange, in Luxembourg, or mail to
each Holder entitled to such money at such Holder's address (as set forth in the
Security Register) notice that such money remains unclaimed and that after a
date specified therein (which shall be at least 30 days from the date of such
publication or mailing) any unclaimed balance of such money then remaining will
be repaid to the Company. After payment to the Company, Holders entitled to such
money must look to the Company for payment as general creditors unless an
applicable law designates another Person, and all liability of the Trustee and
such Paying Agent with respect to such money shall cease.


     SECTION 8.06. REINSTATEMENT.

     If the Trustee or Paying Agent is unable to apply any money or Government
Securities in accordance with 

   79
                                       72

Section 8.01, 8.02 or 8.03, as the case may be, by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Section 8.01, 8.02 or
8.03, as the case may be, until such time as the Trustee or Paying Agent is
permitted to apply all such money or U.S. Government Securities in accordance
with Section 8.01, 8.02 or 8.03, as the case may be; provided that, if the
Company has made any payment of principal of, premium, if any, or interest on
any Notes because of the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money or U.S. Government Securities held by the Trustee or Paying
Agent.

                                  ARTICLE NINE

         SECTION 9.01. WITHOUT CONSENT OF HOLDERS. The Company, when authorized
by a resolution of its Board of Directors (as evidenced by a Board Resolution
delivered to the Trustee), and the Trustee may amend or supplement this
Indenture or the Notes without notice to or the consent of any Holder:

                  (1)      to cure any ambiguity, defect or inconsistency in
         this Indenture; provided that such amendments or supplements shall not,
         in the good faith opinion of the Board of Directors as evidenced by a
         Board Resolution, adversely affect the interests of the Holders in any
         material respect;

                  (2)      to comply with Article Five;

                  (3)      to comply with any requirements of the Commission in
         connection with the qualification of this Indenture under the TIA; (4)
         to evidence and provide for the acceptance of appointment hereunder by
         a successor Trustee;

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

                  (6)      to add one or more subsidiary guarantees on the terms
                           required by this Indenture; or

                  (7)      to make any change that, in the good faith opinion of

                           Resolution, does not materially and adversely affect
                           the rights of any Holder.

                                       73


         SECTION 9.02. WITH CONSENT OF HOLDERS. Subject to Sections 6.04 and
6.07 and without prior notice to the Holders, the Company and the Guarantors,
when authorized by their respective Boards of Directors (as evidenced by a Board
Resolution delivered to the Trustee), and the Trustee may amend this Indenture
and the Notes with the written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding, and the Holders of a majority in
aggregate principal amount of the Notes then outstanding by written notice to
the Trustee may waive future compliance by the Company with any provision of
this Indenture or the Notes.

         case of redemption, on or after the Redemption Date) on any Note;

                  (v)      reduce the percentage or principal amount of

                                       74


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

         After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. The Company will
mail supplemental indentures to Holders upon request. Any failure of the Company
to mail such notice, or any defect therein, shall not, however, in any way
impair or affect the validity of any such supplemental indenture or waiver.

         SECTION 9.03. REVOCATION AND EFFECT OF CONSENT. Until an amendment or
waiver becomes effective, a consent to it by a Holder is a continuing consent by
the Holder and every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the Note of the consenting Holder, even if notation
of the consent is not made on any Note. However, any such Holder or subsequent
Holder may revoke the consent as to its Note or portion of its Note. Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective. An amendment, supplement or waiver shall become effective on receipt
by the Trustee of written consents from the Holders of the requisite percentage
in principal amount of the outstanding Notes.

         The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver. If a record date is fixed, then, notwithstanding the last
two sentences of the immediately preceding paragraph, those persons who were
Holders at such record date (or their duly designated proxies) and only those
persons shall be entitled to consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such persons continue to
be Holders after such record date. No such consent shall be valid or effective
for more than 90 days after such record date.

         After an amendment, supplement or waiver becomes effective, it shall
bind every Holder unless it is of the type described in the second paragraph of
Section 9.02. In case of an amendment or waiver of the type described in the
second paragraph of Section 9.02, the amendment or waiver shall bind each Holder
who has consented to it and every subsequent Holder of a Note that evidences the
same indebtedness as the Note of the consenting Holder.

         SECTION 9.04. NOTATION ON OR EXCHANGE OF NOTES. If an amendment,
supplement or waiver changes the terms of a Note, the Trustee may require the
Holder to deliver such Note to the Trustee. At the Company's expense, the
Trustee may place an appropriate notation on the Note about the changed terms




   82
                                       75


and return it to the Holder and the Trustee may place an appropriate notation on
any Note thereafter authenticated. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation, or issue a new Note, shall not affect the validity and
effect of such amendment, supplement or waiver.

         SECTION 9.05. TRUSTEE TO SIGN AMENDMENTS, ETC. The Trustee shall be
entitled to receive, and shall be fully protected in relying upon, an Opinion of
Counsel stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and that it will be valid and binding upon the Company. Subject to the
preceding sentence, the Trustee shall sign such amendment, supplement or waiver
if the same does not adversely affect the rights, duties, liabilities or
immunities of the Trustee. The Trustee may, but shall not be obligated to,
execute any such amendment, supplement or waiver that affects the Trustee's own
rights, duties or immunities under this Indenture or otherwise.

         SECTION 9.06. CONFORMITY WITH TRUST INDENTURE ACT. Every supplemental
indenture executed pursuant to this Article Nine shall conform to the
requirements of the TIA as then in effect.


                                   ARTICLE TEN
                   SUBORDINATION OF NOTES AND NOTE GUARANTEES

         SECTION 10.01. NOTES AND NOTE GUARANTEES SUBORDINATED TO SENIOR
INDEBTEDNESS. The Company and the Trustee each covenants and agrees, and each
Holder, by its acceptance of a Note, likewise covenants and agrees that all
Notes and Note Guarantees shall be issued subject to the provisions of this
Article Ten; and each Person holding any Note, whether upon original issue or
upon transfer, assignment or exchange thereof, accepts and agrees that Senior
Subordinated Obligations shall, to the extent and in the manner set forth in
this Article Ten, be subordinated in right of payment to the prior payment in
full, in cash or cash equivalents, of all existing and future Senior
Indebtedness, including, without limitation, the Company's obligations under the
Credit Facility, (including any interest accruing subsequent to an event
specified in Sections 6.01(g) and 6.01(h), whether or not such interest is an
allowed claim enforceable against the debtor under the United States Bankruptcy
Code).

         SECTION 10.02. NO PAYMENT ON NOTES IN CERTAIN CIRCUMSTANCES. (a) No
direct or indirect payment (other than a payment or distribution in the form of
Permitted Junior Securities) by or on behalf of the Company or any Guarantor of
Senior Subordinated Obligations (other than with the money and/or Government
Securities held under any defeasance trust established in accordance with



   83
                                       76


this Indenture on the Closing Date and not in violation of the terms of any
Senior Indebtedness), whether pursuant to the terms of the Notes or the Note
Guarantees or upon acceleration or otherwise shall be made if, at the time of
such payment, there exists a default in the payment of all or any portion of the
obligations on any Senior Indebtedness of the Company or such Guarantor and such
default shall not have been cured or waived or the benefits of this sentence
waived by or on behalf of the holders of such Senior Indebtedness.

         (b) During the continuance of any other event of default with respect
to any Designated Senior Indebtedness pursuant to which the maturity thereof may
be accelerated, upon receipt by the Trustee of written notice from the trustee
or other representative for the holders of such Designated Senior Indebtedness
(or the holders of at least a majority in principal amount of such Designated
Senior Indebtedness then outstanding), no payment (other than a payment or
distribution in the form of Permitted Junior Securities) of Senior Subordinated
Obligations (other than with the money and/or Government Securities held under
any defeasance trust established in accordance with this Indenture on the
Closing Date and not in violation of the terms of any Senior Indebtedness) may
be made by or on behalf of the Company or such Guarantor upon or in respect of
the Notes or the Note Guarantees for a period (a "PAYMENT BLOCKAGE PERIOD")
commencing on the date of receipt of such notice and ending 179 days thereafter
(unless, in each case, such Payment Blockage Period shall be terminated by
written notice to the Trustee from such trustee of, or other representatives
for, such holders or by payment in full in cash or cash equivalents of such
Designated Senior Indebtedness or at such time as defaults cease to exist or
have been cured or waived). Not more than one Payment Blockage Period may be
commenced with respect to the Notes (with respect to the Company or any
particular Guarantor) during any period of 360 consecutive days. Notwithstanding
anything in this Indenture to the contrary (with respect to the Company and each
Guarantor), there must be 180 consecutive days in any 360-day period in which no
Payment Blockage Period is in effect. No event of default that existed or was
continuing (it being acknowledged that any subsequent action that would give
rise to an event of default pursuant to any provision under which an event of
default previously existed or was continuing shall constitute a new event of
default for this purpose) on the date of the commencement of any Payment
Blockage Period with respect to the Designated Senior Indebtedness initiating
such Payment Blockage Period shall be, or shall be made, the basis for the
commencement of a second Payment Blockage Period by the representative for, or
the holders of, such Designated Senior Indebtedness, whether or not within a
period of 360 consecutive days, unless such event of default shall have been
cured or waived for a period of not less than 60 consecutive days.

         (c) In the event that, notwithstanding the foregoing, any payment shall
be received by the Trustee or any Holder when such payment is prohibited by
Section 10.02(a) or 10.02(b), the Trustee shall promptly notify the holders of
Senior Indebtedness of such prohibited payment and such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness or their respective representatives, or 





   84

                                       77


to the trustee or trustees under any indenture pursuant to which any of such
Senior Indebtedness may have been issued, as their respective interests may
appear, but only to the extent that, upon notice from the Trustee to the holders
of Senior Indebtedness that such prohibited payment has been made, the holders
of the Senior Indebtedness (or their representative or representatives of a
trustee) within 30 days of receipt of such notice from the Trustee notify the
Trustee of the amounts then due and owing on the Senior Indebtedness, if any,
and only the amounts specified in such notice to the Trustee shall be paid to
the holders of Senior Indebtedness and any excess above such amounts due and
owing on Senior Indebtedness shall be paid to the Company.

         SECTION 10.03. PAYMENT OVER PROCEEDS UPON DISSOLUTION, BANKRUPTCY, ETC.
(a) Upon any payment or distribution of assets or securities of the Company or
any Guarantor of any kind or character, whether in cash, property or securities
(other than with the money and/or Government Securities held under any
defeasance trust established in accordance with this Indenture and not in
violation of the terms of any Senior Indebtedness), in connection with any
dissolution or winding up or total or partial liquidation or reorganization of
the Company or any Guarantor, whether voluntary or involuntary, or in
bankruptcy, insolvency, receivership or other proceedings or other marshaling of
assets for the benefit of creditors, all amounts due or to become due upon all
Senior Indebtedness (including any interest accruing subsequent to an event
specified in Sections 6.01(g) and 6.01(h), whether or not such interest is an
allowed claim enforceable against the debtor under the United States Bankruptcy
Code) shall first be paid in full, in cash or cash equivalents, before the
Holders or the Trustee on their behalf shall be entitled to receive any payment
by (or on behalf of) the Company or such Guarantor on account of Senior
Subordinated Obligations, or any payment to acquire any of the Notes for cash,
property or securities, or any distribution with respect to the Notes of any
cash, property or securities (other than a payment or distribution in the form
of Permitted Junior Securities). Before any payment may be made by, or on behalf
of, the Company or such Guarantor on any Senior Subordinated Obligations (other
than with the money and/or Government Securities held under any defeasance trust
established in accordance with this Indenture and not in violation of the terms
of any Senior Indebtedness) in connection with any such dissolution, winding up,
liquidation or reorganization, any payment or distribution of assets or
securities of the Company or such Guarantor of any kind or character, whether in
cash, property or securities (other than a payment or distribution in the form
of Permitted Junior Securities), to which the Holders or the Trustee on their
behalf would be entitled, but for the provisions of this Article Ten, shall be
made by the Company, such Guarantor or by any receiver, trustee in bankruptcy,
liquidating trustee, agent or other similar Person making such payment or
distribution, or by the Holders or the Trustee if received by them or it,
directly to the holders of Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders) or
their representatives or to any trustee or trustees under any other indenture
pursuant to which any such Senior Indebtedness may have been issued, as their
respective interests appear, to the extent necessary to pay all such Senior



   85
                                       78


Indebtedness in full, in cash or cash equivalents after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders of
such Senior Indebtedness.

         (b) To the extent any payment of Senior Indebtedness (whether by or on
behalf of the Company or any Guarantor, as proceeds of security or enforcement
of any right of setoff or otherwise) is declared to be fraudulent or
preferential, set aside or required to be paid to any receiver, trustee in
bankruptcy, liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then
if such payment is recovered by, or paid over to, such receiver, trustee in
bankruptcy, liquidating trustee or other similar Person, the Senior Indebtedness
or part thereof originally intended to be satisfied shall be deemed to be
reinstated and outstanding as if such payment had not occurred. To the extent
the obligation to repay any Senior Indebtedness is declared to be fraudulent,
invalid, or otherwise set aside under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then the obligation so declared
fraudulent, invalid or otherwise set aside (and all other amounts that would
come due with respect thereto had such obligation not been so affected) shall be
deemed to be reinstated and outstanding as Senior Indebtedness for all purposes
hereof as if such declaration, invalidity or setting aside had not occurred.

         (c) In the event that, notwithstanding the foregoing provision
prohibiting such payment or distribution, any payment or distribution of assets
or securities of the Company of any kind or character, whether in cash, property
or securities, shall be received by the Trustee or any Holder at a time when
such payment or distribution is prohibited by Section 10.03(a) and before all
obligations in respect of Senior Indebtedness are paid in full, in cash or cash
equivalents, such payment or distribution shall be received and held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness (pro rata to such holders on the basis of such respective
amount of Senior Indebtedness held by such holders) or their representatives, or
to the trustee or trustees under any indenture pursuant to which any such Senior
Indebtedness may have been issued, as their respective interests appear, for
application to the payment of Senior Indebtedness remaining unpaid until all
such Senior Indebtedness has been paid in full, in cash or cash equivalents,
after giving effect to any concurrent payment, distribution or provision
therefor to or for the holders of such Senior Indebtedness.

         (d) For purposes of this Section 10.03, the words "cash, property or
securities" shall not be deemed to include, so long as the effect of this clause
is not to cause the Notes or the Note Guarantees to be treated in any case or
proceeding or similar event described in this Section 10.03 as part of the same
class of claims as the Senior Indebtedness or any class of claims pari passu
with, or senior to, the Senior Indebtedness for any payment or distribution,
Permitted Junior Securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment; provided that (1) if a new
corporation results from such reorganization or readjustment, such corporation
assumes the Senior Indebtedness and (2) the 



   86
                                       79


rights of the holders of the Senior Indebtedness are not, without the consent of
such holders, altered by such reorganization or readjustment. The consolidation
of the Company with, or the merger of the Company with or into, another
corporation or the liquidation or dissolution of the Company following the sale,
conveyance, transfer, lease or other disposition of all or substantially all of
its property and assets to another corporation upon the terms and conditions
provided in Article Five of this Indenture (including in connection with the
Acquisition) shall not be deemed a dissolution, winding up, liquidation or
reorganization for the purposes of this Section 10.03 if such other corporation
shall, as a part of such consolidation, merger, sale, conveyance, transfer,
lease or other disposition, comply (to the extent required) with the conditions
stated in Article Five of this Indenture.

         (e) In the event of any bankruptcy, insolvency, receivership or other
proceeding or other marshalling of assets for the benefit of creditors or any
total or partial liquidation or reorganization of the Company or any of the
Guarantors, whether voluntary or involuntary, the Holders shall retain the right
to vote and otherwise act with respect to the Notes (including, without
limitation, the right to vote to accept or reject any plan of partial or
complete liquidation, reorganization, arrangement, composition or extension),
provided that the Holders shall not in any way take or omit any action so as to
contest (i) the validity of any Senior Indebtedness or any collateral therefor
or guaranties thereof, (ii) the relative rights and duties of any holders of any
Senior Indebtedness established in any instruments or agreements creating or
evidencing any of the Senior Indebtedness with respect to any of such collateral
or guaranties or (iii) the Holders' obligations and agreements set forth herein.
In the event that any Holder or the Trustee fails to file a proof of claim in
any such proceeding within five days of the deadline of such filing, the
representatives of the Senior Indebtedness shall be permitted to file such claim
on behalf of such Holder.

         SECTION 10.04. SUBROGATION. (a) Upon the payment in full of all Senior
Indebtedness in cash or cash equivalents, the Holders shall be subrogated to the
rights of the holders of Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company made on such Senior
Indebtedness until the principal of, premium, if any, and interest on the Notes
shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of the Senior Indebtedness of any cash, property or
securities to which the Holders or the Trustee on their behalf would be entitled
except for the provisions of this Article Ten, and no payment pursuant to the
provisions of this Article Ten to the holders of Senior Indebtedness by Holders
or the Trustee on their behalf shall, as between the Company, its creditors
other than holders of Senior Indebtedness, and the Holders, be deemed to be a
payment by the Company to or on account of the Senior Indebtedness. It is
understood that the provisions of this Article Ten are intended solely for the
purpose of defining the relative rights of the Holders, on the one hand, and the
holders of the Senior Indebtedness, on the other hand.

         (b) If any payment or distribution to which the Holders would otherwise
have been 





   87
                                       80


entitled but for the provisions of this Article Ten shall have been applied,
pursuant to the provisions of this Article Ten, to the payment of all amounts
payable under Senior Indebtedness, then, and in such case, the Holders shall be
entitled to receive from the holders of such Senior Indebtedness, unless
otherwise required by applicable law, any payments or distributions received by
such holders of Senior Indebtedness in excess of the amount required to make
payment in full, in cash or cash equivalents, of such Senior Indebtedness of
such holders.

         SECTION 10.05. OBLIGATIONS OF COMPANY UNCONDITIONAL. (a) Nothing
contained in this Article Ten or elsewhere in this Indenture or in the Notes is
intended to or shall impair, as among the Company and the Holders, the
obligation of the Company, which is absolute and unconditional, to pay to the
Holders the principal of, premium, if any, and interest on the Notes as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders and creditors of
the Company other than the holders of the Senior Indebtedness, nor shall
anything herein or therein prevent the Holders or the Trustee on their behalf
from exercising all remedies otherwise permitted by applicable law upon default
under this Indenture, subject to the rights, if any, under this Article Ten of
the holders of the Senior Indebtedness.

         (b) Without limiting the generality of the foregoing, nothing contained
in this Article Ten will restrict the right of the Trustee or the Holders to
take any action to declare the Notes to be due and payable prior to their Stated
Maturity pursuant to Section 6.01 or to pursue any rights or remedies hereunder;
provided, however, that all Senior Indebtedness then due and payable or
thereafter declared to be due and payable shall first be paid in full, in cash
or cash equivalents, before the Holders or the Trustee (to the extent provided
in Section 6.10) are entitled to receive any direct or indirect payment from the
Company of Senior Subordinated Obligations.

         SECTION 10.06. NOTICE TO TRUSTEE. (a) The Company shall give prompt
written notice to the Trustee of any fact known to the Company that would
prohibit the making of any payment to or by the Trustee in respect of the Notes
pursuant to the provisions of this Article Ten. The Trustee shall not be charged
with the knowledge of the existence of any default or event of default with
respect to any Senior Indebtedness or of any other facts that would prohibit the
making of any payment to or by the Trustee unless and until the Trustee shall
have received notice in writing at its Corporate Trust Office to that effect
signed by an Officer of the Company, or by a holder of Senior Indebtedness or
trustee or agent thereof; and prior to the receipt of any such written notice,
the Trustee shall, subject to Article Seven, be entitled to assume that no such
facts exist; provided that, if the Trustee shall not have received the notice
provided for in this Section 10.06 at least one Business Day prior to the date
upon which, by the terms of this Indenture, any monies shall become payable for
any purpose (including, without limitation, the payment of the





   88
                                       81


principal of, premium, if any, or interest on any Note), then, notwithstanding
anything herein to the contrary, the Trustee shall have full power and authority
to receive any monies from the Company and to apply the same to the purpose for
which they were received, and shall not be affected by any notice to the
contrary that may be received by it on or after such prior date except for an
acceleration of the Notes prior to such application. Nothing contained in this
Section 10.06 shall limit the right of the holders of Senior Indebtedness to
recover payments as contemplated by this Article Ten. The foregoing shall not
apply if the Paying Agent is the Company. The Trustee shall be entitled to rely
on the delivery to it of a written notice by a Person representing himself or
itself to be a holder of any Senior Indebtedness (or a trustee on behalf of, or
other representative of, such holder) to establish that such notice has been
given by a holder of such Senior Indebtedness or a trustee or representative on
behalf of any such holder.

         (b) In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Senior Indebtedness to participate in any payment or distribution pursuant to
this Article Ten, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article Ten and, if such evidence is not furnished to the
Trustee, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

         SECTION 10.07. RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
AGENT. Upon any payment or distribution of assets or securities referred to in
this Article Ten, the Trustee and the Holders shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which bankruptcy,
dissolution, winding up, liquidation or reorganization proceedings are pending,
or upon a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar Person making such payment or distribution,
delivered to the Trustee or to the Holders for the purpose of ascertaining the
persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Ten.

         SECTION 10.08. TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS. (a) The
Trustee and any Paying Agent shall be entitled to all the rights set forth in
this Article Ten with respect to any Senior Indebtedness that may at any time be
held by it in its individual or any other capacity to the same extent as any
other holder of Senior Indebtedness and nothing in this Indenture shall deprive
the Trustee or any Paying Agent of any of its rights as such holder.


   89
                                       82


         (b) With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article Ten and in Section 6.10, and no
implied covenants or obligations with respect to the holders of Senior
Indebtedness shall be read into this Indenture against the Trustee.

         SECTION 10.09. SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS
OF THE COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS. No right of any present or
future holders of any Senior Indebtedness to enforce subordination as provided
in this Article Ten will at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or any Guarantor or by any act
or failure to act, in good faith, by any such holder, or by any noncompliance by
the Company or any Guarantor with the terms of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.
The provisions of this Article Ten are intended to be for the benefit of, and
shall be enforceable directly by, the holders of Senior Indebtedness.

         SECTION 10.10. HOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE SUBORDINATION OF
NOTES. Each Holder by its acceptance of any Notes authorizes and expressly
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article Ten, and
appoints the Trustee its attorney-in-fact for such purposes, including, in the
event of any dissolution, winding up, liquidation or reorganization of the
Company (whether in bankruptcy, insolvency, receivership, reorganization or
similar proceedings or upon an assignment for the benefit of creditors or
otherwise) tending towards liquidation of the property and assets of the
Company, the filing of a claim for the unpaid balance of its Notes in the form
required in those proceedings. If the Trustee does not file a proper claim or
proof in indebtedness in the form required in such proceeding at least 30 days
before the expiration of the time to file such claim or claims, each holder of
Senior Indebtedness is hereby authorized to file an appropriate claim for and on
behalf of the Holders.

         SECTION 10.11. NOT TO PREVENT EVENTS OF DEFAULT. The failure to make a
payment on account of principal of, premium, if any, or interest on the Notes by
reason of any provision of this Article Ten will not be construed as preventing
the occurrence of an Event of Default.

         SECTION 10.12. TRUSTEE'S COMPENSATION NOT PREJUDICED. Subject to
Section 6.10, nothing in this Article Ten will apply to amounts due to the
Trustee pursuant to other sections of this Indenture, including Section 7.07.

         SECTION 10.13. NO WAIVER OF SUBORDINATION PROVISIONS. Without in any
way limiting the generality of Section






   90
                                       83


10.09, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders, without
incurring responsibility to the Holders and without impairing or releasing the
subordination provided in this Article Ten or the obligations hereunder of the
Holders to the holders of Senior Indebtedness, do any one or more of the
following: (a) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior Indebtedness or any instrument
evidencing the same or any agreement under which Senior Indebtedness is
outstanding or secured; (b) sell, exchange, release or otherwise deal with any
property pledged, mortgaged or otherwise securing Senior Indebtedness; (c)
release any Person liable in any manner for the collection of Senior
Indebtedness; and (d) exercise or refrain from exercising any rights against the
Company and any other Person.

         SECTION 10.14. PAYMENTS MAY BE PAID PRIOR TO DISSOLUTION. Nothing
contained in this Article Ten or elsewhere in this Indenture shall prevent (i)
the Company except under the conditions described in Section 10.02 or 10.03,
from making payments of principal of, premium, if any, and interest on the
Notes, or from depositing with the Trustee any money for such payments, or (ii)
the application by the Trustee of any money deposited with it for the purpose of
making such payments of principal of, premium, if any, and interest on the Notes
to the holders entitled thereto unless, at least one Business Day prior to the
date upon which such payment becomes due and payable, the Trustee shall have
received the written notice provided for in Section 10.02(b) (or there shall
have been an acceleration of the Notes prior to such application) or in Section
10.06. The Company shall give prompt written notice to the Trustee of any
dissolution, winding up, liquidation or reorganization of the Company.

         SECTION 10.15. CONSENT OF HOLDERS OF SENIOR INDEBTEDNESS UNDER THE
CREDIT FACILITY. The provisions of this Article Ten (including the definitions
contained in this Article and references to this Article contained in this
Indenture) shall not be amended in a manner that would adversely affect the
rights of the holders of Senior Indebtedness under the Credit Facility, and no
such amendment shall become effective unless the holders of Senior Indebtedness
under the Credit Facility shall have consented (in accordance with the
provisions of the Credit Facility) to such amendment. The Trustee shall be
entitled to receive and rely on an Officers' Certificate stating that such
consent has been given.

         SECTION 10.16. TRUST MONEYS NOT SUBORDINATED. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of
Government Securities held in trust under Article Eight by the Trustee for the
payment of principal of, premium, if any, and interest on the Notes shall not be
subordinated to the prior payment of any Senior Indebtedness (provided that, at
the time deposited, such deposit did not violate any then outstanding Senior
Indebtedness), and none of the Holders shall be obligated to pay over any such
amount to any holder of Senior 





   91
                                       84


Indebtedness.

                                 ARTICLE ELEVEN
                               GUARANTEE OF NOTES

         SECTION 11.01. NOTE GUARANTEE. Subject to the provisions of this
Article Eleven, each of the Guarantors hereby, jointly and severally, fully,
unconditionally and irrevocably guarantees to each Holder and to the Trustee on
behalf of the Holders: (i) the due and punctual payment of the principal of,
premium, if any, on and interest on each Note, when and as the same shall become
due and payable, whether at maturity, by acceleration or otherwise, the due and
punctual payment of interest on the overdue principal of and interest, if any,
on the Notes, to the extent lawful, and the due and punctual performance of all
other obligations of the Company to the Holders or the Trustee, all in
accordance with the terms of such Note and this Indenture and (ii) in the case
of any extension of time of payment or renewal of any Notes or any of such other
obligations, that the same will be promptly paid in full when due or performed
in accordance with the terms of the extension or renewal, at Stated Maturity, by
acceleration or otherwise. Each of the Guarantors hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
merger or bankruptcy of the Company, any right to require a proceeding first
against the Company, the benefit of discussion, protest or notice with respect
to any such Note or the debt evidenced thereby and all demands whatsoever
(except as specified above), and covenants that this Note Guarantee will not be
discharged as to any such Note except by payment in full of the principal
thereof and interest thereon and as provided in Section 8.01 and Section 8.02,
or if all or substantially all of such Guarantor's assets are sold, or all of
its Capital Stock is sold, in each case in a transaction in compliance with
Section 4.11. The maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six for the purposes of this Article Eleven.
In the event of any declaration of acceleration of such obligations as provided
in Article Six, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purpose of this
Article Eleven. In addition, without limiting the foregoing provisions, upon the
effectiveness of an acceleration under Article Six, the Trustee shall promptly
make a demand for payment on the Notes under the Note Guarantees provided for in
this Article Eleven.

         If the Trustee or the Holder of any Note is required by any court or
otherwise to return to the Company or any Guarantor, or any custodian, receiver,
liquidator, trustee, sequestrator or other similar official acting in relating
to the Company or such Guarantor, any amount paid to the Trustee or such Holder
in respect of a Note, the Note Guarantees, to the extent theretofore discharged,
shall be reinstated in full force and effect. Each of the Guarantors further
agrees, to the fullest extent that it may lawfully do so, that, as between it,
on the one hand, and the Holders and the Trustee, on the other hand, the
maturity of the obligations 




   92

                                       85


guaranteed hereby may be accelerated as provided in Article Six hereof for the
purposes of its Note Guarantee, notwithstanding any stay, injunction or other
prohibition extant under any applicable bankruptcy law preventing such
acceleration in respect of the obligations guaranteed hereby.

         Each of the Guarantors hereby irrevocably waives any claim or other
right which it may now or hereafter acquire against the Company or any other
Guarantor that arise from the existence, payment, performance or enforcement of
its obligations under its Note Guarantee and this Indenture, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, any right to participate in any claim or remedy of the Holders
against the Company or any Guarantor or any collateral which any such Holder or
the Trustee on behalf of such Holder hereafter acquires, whether or not such
claim, remedy or right arises in equity, or under contract, statute or common
law, including, without limitation, the right to take or receive from the
Company or a Guarantor, directly or indirectly, in cash or other property or by
setoff or in any other manner, payment or Note on account of such claim or other
rights, except to the extent that such claim or right would be necessary to
preserve the enforceability of a Note Guarantee as provided in Section 11.05. If
any amount shall be paid to a Guarantor in violation of the preceding sentence
and the principal of, premium, of any, and accrued interest on the Notes shall
not have been paid in full, such amount shall be deemed to have been paid to
such Guarantor for the benefit of, and held in trust for the benefit of, the
Holders, and shall forthwith be paid to the Trustee for the benefit of the
Holders to be credited and applied upon the principal of, premium, if any, and
accrued interest on the Notes. Each of the Guarantors acknowledges that it will
receive direct and indirect benefits from the issuance of the Notes pursuant to
this Indenture and that the waivers set forth in this Section 11.01 are
knowingly made in contemplation of such benefits.

         The Note Guarantees set forth in this Section 11.01 shall not be valid
or become obligatory for any purpose with respect to a Note until the
certificate of authentication on such Note shall have been signed by or on
behalf of the Trustee.

         SECTION 11.02. OBLIGATIONS UNCONDITIONAL. Subject to Section 11.05,
nothing contained in this Article Eleven or elsewhere in this Indenture or in
the Notes is intended to or shall impair, as among any Guarantor and the holders
of the Notes, the obligation of such Guarantor, which is absolute and
unconditional, upon failure by the Company, to pay to the holders of the Notes
the principal of, premium, if any, and interest on the Notes as and when the
same shall become due and payable in accordance with their terms, or is intended
to or shall affect the relative rights of the holders of Notes and creditors of
such Guarantor, nor shall anything herein or therein prevent the holder of any
Note or the Trustee on their behalf from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture.

         Without limiting the foregoing, nothing contained in this Article
Eleven will restrict the 



   93
                                       86


right of the Trustee or the holders of the Notes to take any action to declare
the Note Guarantee to be due and payable prior to the Stated Maturity of the
Notes pursuant to Section 6.02 or to pursue any rights or remedies hereunder.

         SECTION 11.03. NOTICE TO TRUSTEE. Each Guarantor shall give prompt
written notice to the Trustee of any fact known to such Guarantor which would
prohibit the making of any payment to or by the Trustee in respect of the Note
Guarantee of such Guarantor pursuant to the provisions of this Article Eleven.

         SECTION 11.04. THIS ARTICLE NOT TO PREVENT EVENTS OF DEFAULT. The
failure to make a payment on account of principal of, premium, if any, or
interest on the Notes by reason of any provision of this Article will not be
construed as preventing the occurrence of an Event of Default.

         SECTION 11.05. FRAUDULENT CONVEYANCE LIMITATION. Notwithstanding any
other provision of this Indenture or the Notes, no Note Guarantee shall be
enforceable against any Guarantor in an amount that would cause such Note
Guarantee to be a fraudulent conveyance under applicable law.

         SECTION 11.06. ADDITIONAL GUARANTORS. The Company shall cause any
Person (other than a Foreign Subsidiary) that becomes a Restricted Subsidiary on
or after the Closing Date to execute a supplemental indenture as a Guarantor.

         SECTION 11.07. SUBORDINATION. The obligations of the Guarantors under
this Article Eleven are obligations of the Guarantors subject in all respects to
the subordination provisions of Article Ten hereof.



                                 ARTICLE TWELVE
                                  MISCELLANEOUS

         SECTION 12.01. TRUST INDENTURE ACT OF 1939. Prior to the effectiveness
of the Registration Statement, this Indenture shall incorporate and be governed
by the provisions of the TIA that are required to be part of and to govern
indentures qualified under the TIA. After the effectiveness of the Registration
Statement, this Indenture shall be subject to the provisions of the TIA that are
required to be a part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

         SECTION 12.02. NOTICES. Any notice or communication shall be
sufficiently given if in writing and delivered in person, mailed by first-class
mail or sent by telecopier transmission addressed as follows:

                  Attention:  Patricia Randall

         IF TO THE TRUSTEE:

                  STATE STREET BANK AND TRUST COMPANY
                  Two International Place
                  Boston, MA 02110
                  Telecopier No.: (617) 664-5150
                  Attention: Corporate Trust Division

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

         Any notice or communication mailed to a Holder shall be mailed to it at
its address as it appears in each case on the Security Register by first-class
mail and shall be sufficiently given to him if so mailed within the time
prescribed. Any notice or communication shall also be so mailed to any Person
described in TIA Section 313(c), to the extent required by the TIA. In addition,
so long as the Notes are listed on the Luxembourg Stock Exchange and it is
required by the rules of such stock exchange, such notices shall be published in
English in a leading newspaper having general circulation in Luxembourg (which
is expected to be the Luxembourger Wort) or if any such case is not applicable,
in one other leading English language daily newspaper with general circulation
in Europe, such newspaper being published on each Business Day in morning
editions, whether or not it shall be published on a Saturday, Sunday or a
holiday. COPIES of any such communication or notice to a Holder shall also be
mailed to the Trustee and each Agent at the same time.

         Failure to mail a notice or communication to a Holder as provided
herein or any defect in any such notice or communication shall not affect its
sufficiency with respect to other Holders. Except for a notice to the Trustee,
which is deemed given only when received, and except as otherwise provided in
this Indenture, if a notice or communication is mailed in the manner provided in
this Section 12.02, it is duly given, whether or not the addressee receives it.

         Where this Indenture provides for notice in any manner, such notice may
be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Holders shall be filed with 



   95
                                       88


the Trustee, but such filing shall not be a condition precedent to the validity
of any action taken in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

         Holders may communicate pursuant to TIA Section 312(b) with other
Holders with respect to their rights under this Indenture or the Notes. The
Company, the Guarantor, the Trustee, the Registrar and anyone else shall have
the protection of TIA Section 312(c).

         SECTION 12.03. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT. Upon
any request or application by the Company to the Trustee to take any action
under this Indenture, the Company shall furnish to the Trustee:

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

                  (ii)     an Opinion of Counsel stating that, in the opinion of
         such Counsel, all such conditions precedent have been complied with.

         SECTION 12.04. STATEMENTS REQUIRED IN CERTIFICATE OR OPINION. Each
certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture shall include:

                  (i)      a statement that each person signing such certificate
         or opinion has read such covenant or condition and the definitions
         herein relating thereto;

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

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

                  (iv)     a statement as to whether or not, in the opinion of
         each such person, such condition or covenant has been complied with;
         provided, however, that, with respect to matters of fact, an Opinion of
         Counsel may rely on an Officers' Certificate 





   96

                                       89


or certificates of public officials.

         SECTION 12.05. RULES BY TRUSTEE, PAYING AGENT OR REGISTRAR. The Trustee
may make reasonable rules for action by or at a meeting of Holders. The Paying
Agent or Registrar may make reasonable rules for its functions.

         SECTION 12.06. PAYMENT DATE OTHER THAN A BUSINESS DAY. If an Interest
Payment Date, Redemption Date, Payment Date, Stated Maturity or date of maturity
of any Note shall not be a Business Day, then payment of principal of, premium,
if any, or interest on such Note, as the case may be, need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Payment Date or Redemption
Date, or at the Stated Maturity or date of maturity of such Note; provided that
no interest shall accrue for the period from and after such Interest Payment
Date, Payment Date, Redemption Date, Stated Maturity or date of maturity, as the
case may be.

         SECTION 12.07. GOVERNING LAW. This Indenture and the Notes shall be
governed by the laws of the State of New York. The Trustee, the Company, the
Guarantors and the Holders agree to submit to the jurisdiction of the courts of
the State of New York in any action or proceeding arising out of or relating to
this Indenture or the Notes.

         SECTION 12.08. NO ADVERSE INTERPRETATION OF OTHER AGREEMENTS. This
Indenture may not be used to interpret another indenture, loan or debt agreement
of the Company or any Subsidiary of the Company. Any such indenture, loan or
debt agreement may not be used to interpret this Indenture.

         SECTION 12.09. NO RECOURSE AGAINST OTHERS. No recourse for the payment
of the principal of, premium, if any, or interest on any of the Notes, or for
any claim based thereon or otherwise in respect thereof, and no recourse under

Indenture or in any of the Notes, or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator or against any past,
present or future partner, stockholder, other equity holder, officer, director,
employee or controlling person, as such, of the Company or of any successor
Person, either directly or through the Company or any successor Person, whether
by virtue of any constitution, statute or rule of law, or by the enforcement of
any assessment or penalty or otherwise; it being expressly understood that all
such liability is hereby expressly waived and released as a condition of, and as
a consideration for, the execution of this Indenture and the issue of the Notes.

         SECTION 12.10. SUCCESSORS. All agreements of the Company in this
Indenture and the Notes shall bind its successors. All agreements of the 





   97
                                       90


Trustee in this Indenture shall bind its successor.

         SECTION 12.11. DUPLICATE ORIGINALS. The parties may sign any number of
copies of this Indenture. Each signed copy shall be an original, but all of them

                             [REVERSE SIDE OF NOTE]

                                HADCO CORPORATION

                    9 1/2% Senior Subordinated Note due 2008



1.  PRINCIPAL AND INTEREST.

         The Company will pay the principal of this Note on June 15, 2008.

         The Company promises to pay interest on the principal amount of this
Note on each Interest Payment Date, as set forth below, at the rate per annum
shown above.

         Interest will be payable semiannually (to the holders of record of the
Notes at the close of business on the June 1 or December 1 immediately preceding
the Interest Payment Date) on each Interest Payment Date, commencing December
15, 1998.

         If an exchange offer (the "Exchange Offer") registered under the
Securities Act is not consummated or a shelf registration statement (the "Shelf
Registration Statement") under the Securities Act with respect to resales of the
Notes is not declared effective by the Commission on or before November 18, 1998
in accordance with the terms of the Registration Rights Agreement dated as of
May 13, 1998 between the Company and Hadco Santa Clara, Inc. Hadco Phoenix,
Inc., CCIR of California Corp. and CCIR of Texas Corp., as guarantors
(collectively, the "Guarantors") and Morgan Stanley & Co. Incorporated, Merrill
Lynch, Pierce, Fenner and Smith Incorporated, BancAmerica Robertson Stephens and
BT Alex. Brown Incorporated (a "Registration Default"), the annual interest rate
borne by the Notes shall be increased by 0.5% from the rate shown above accruing
from the date of such Registration Default, payable in cash semiannually, in
arrears, on each Interest Payment Date, commencing with the first such date
occurring after any such Registration Default until the Exchange Offer is
consummated or the Shelf Registration Statement is declared effective. After the
date on which such Registration Default is cured, the interest rate on the Notes
will revert to the interest rate shown above. The Holder of this Note is
entitled to the benefits of such Registration Rights Agreement.

         Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from May 18, 1998;
provided that, if there is no existing default in the payment of interest and
this Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.


   102
                                      A-4


         The Company shall pay interest on overdue principal and premium, if
any, and interest on overdue installments of interest, to the extent lawful, at
a rate per annum that is 2% in excess of the rate otherwise payable.

2.  METHOD OF PAYMENT.

         The Company will pay interest (except defaulted interest) on the
principal amount of the Notes as provided above on each June 15 and December 15,
commencing December 15, 1998 to the persons who are Holders (as reflected in the
Security Register at the close of business on the June 1 or December 1
immediately preceding the Interest Payment Date), in each case, even if the Note
is canceled on registration of transfer or registration of exchange after such
record date; provided that, with respect to the payment of principal, the
Company will make payment to the Holder that surrenders this Note to a Paying
Agent on or after June 15, 2008.

         The Company will pay principal, premium, if any, and as provided above,
interest in money of the United States that at the time of payment is legal
tender for payment of public and private debts. However, the Company may pay
principal, premium, if any, and interest by its check payable in such money. It
may mail an interest check to a Holder's registered address (as reflected in the
Security Register). If a payment date is a date other than a Business Day at a
place of payment, payment may be made at that place on the next succeeding day
that is a Business Day and no interest shall accrue for the intervening period.

3.  PAYING AGENT AND REGISTRAR.

         Initially, the Trustee will act as authenticating agent, Paying Agent
and Registrar. The Company may change any authenticating agent, Paying Agent or
Registrar without notice. The Company, any Subsidiary or any Affiliate of any of
them may act as Paying Agent, Registrar or co-Registrar.

4.  INDENTURE; LIMITATIONS.

         The Company issued the Notes under an Indenture dated as of May 18,
1998 (the "Indenture"), between the Company, the Guarantors and State Street
Bank and Trust Company, trustee (the "Trustee"). Capitalized terms herein are

a statement of all such terms. To the extent permitted by applicable law, in the
event of any inconsistency between the terms of this Note and the terms of the
Indenture, the terms of the Indenture shall control.

of Notes initially issued remain outstanding after each such redemption and (ii)

option, in whole or in part, at any time or from time to time, upon not less

right of holders of record on the Relevant Record Date to receive interest due
on the relevant interest payment date).

The Registrar may require a Holder, among other things, to furnish appropriate

transfer or exchange of any Notes for a period of 15 days before the day of
mailing of a notice of redemption of Notes selected for redemption.

8.  PERSONS DEEMED OWNERS.

         If money for the payment of principal, premium, if any, or interest
remains unclaimed for two years, the Trustee and the Paying Agent will pay the
money back to the Company at its request. After that, Holders entitled to the
money must look to the Company for payment, unless an abandoned property law
designates another Person, and all liability of the Trustee and such Paying
Agent with respect to such money shall cease.

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

Dear Sirs:

         This letter relates to U.S. $__________ principal amount of Notes
represented by a Note (the "Legended Note") which bears a legend outlining
restrictions upon transfer of such Legended Note. Pursuant to Section 2.02 of
the Indenture dated as of May 18, 1998 (the "Indenture") relating to the Notes,
we hereby certify that we are (or we will hold such securities on behalf of) a
person outside the United States to whom the Notes could be transferred in
accordance with Rule 904 of Regulation promulgated under the U.S. Securities Act
of 1933. Accordingly, you are hereby requested to exchange the legended
certificate for an unlegended certificate representing an identical principal
amount of Notes, all in the manner provided for in the Indenture.

        You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby. Terms used in this certificate have the

             9 1/2% Senior Subordinated Notes due 2008 (the "Notes")
             -------------------------------------------------------

Dear Sirs:

         In connection with our proposed purchase of $_______________ aggregate
principal amount of the Notes, we confirm that:


         1. We understand that any subsequent transfer of the Notes is subject
to certain restrictions and conditions set forth in the Indenture dated as of
May 18, 1998 (the "Indenture") relating to the Notes and the undersigned agrees
to be bound by, and not to resell, pledge or otherwise transfer the Notes except
in compliance with such restrictions and conditions and the Securities Act of
1933, amended (the "Securities Act").

        2. We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes may not be offered or
sold except as permitted in the following sentence. We agree, on our own behalf
and on behalf of any accounts for which we are acting as hereinafter stated,
that if we should sell any Notes within the time period referred to in Rule
144(k) of the Securities Act, we will do so only (A) to the Company or any
subsidiary thereof, (B) in accordance with Rule 144A under the Securities Act to
a "qualified institutional buyer" (as defined therein), (C) to an institutional
"accredited investor" (as defined below) that, prior to such transfer, furnishes
(or has furnished on its behalf by a U.S. broker-dealer) to you and to the
Company a signed letter substantially in the form of this letter and, if such
transfer is in respect of an aggregate principal amount of less than $100,000,
an opinion of counsel acceptable to the Company that such transfer is in
compliance with the Securities Act, (D) outside the United States in accordance
with Rule 904 of Regulation S under the Securities Act, (E) pursuant to the
exemption from registration provided by Rule 144 under the Securities Act (if
available) or (F) pursuant to an effective registration statement under the
Securities Act, and we further agree to provide to any person purchasing any of
the 



   114

Notes from us a notice advising such purchaser that resales of the Notes are
restricted as stated herein.

         3. We understand that, on any proposed resale of any Notes, we will be
required to furnish to you and the Company such certifications, legal opinions
and other information as you and the Company may reasonably require to confirm
that the proposed sale complies with the foregoing restrictions. We further
understand that the Notes purchased by us will bear a legend to the foregoing
effect.

         4. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and 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 Notes, and we and
any accounts for which we are acting are each able to bear the economic risk of
our or its investment.

         5. We are acquiring the Notes purchased by us for our own account or
for one or more accounts (each of which is an institutional "accredited
investor") as to each of which we exercise sole investment discretion.

        You and the Company are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.

                                             Very truly yours,
