                  (4) neither the Company nor any Restricted Subsidiary shall at
               any time

                         (a) provide a guarantee of, or similar credit support
                    to, any Indebtedness of such Subsidiary (including any

                    Indebtedness),

                         (b) be directly or indirectly liable for any
                    Indebtedness of such Subsidiary or

                         (c) be directly or indirectly liable for any other
                    Indebtedness that provides that the holder thereof may (upon
                    notice, lapse of time or both) declare a default thereon (or
                    cause the payment thereof to be accelerated or payable prior
                    to its final scheduled maturity) upon the occurrence of a
                    default with respect to any other Indebtedness that is
                    Indebtedness of such Subsidiary (including any corresponding
                    right to take enforcement action against such Subsidiary),

                  except in the case of clause (a) or (b) above to the extent

                         (a) that the Company or such Restricted Subsidiary
                    could otherwise provide such a guarantee or incur such
                    Indebtedness (other than as Permitted Indebtedness)
                    pursuant to Section 4.10 and

                         (b) the provision of such guarantee and the incurrence
                    of such Indebtedness otherwise would be permitted under
                    Section 4.11.

                  The Board of Directors of the Company may designate any
Unrestricted Subsidiary or any Person that is to become a Subsidiary as a
Restricted Subsidiary if immediately after giving effect to such action (and
treating any Indebtedness of such Unrestricted Subsidiary or Person as having
been incurred at the time of such action),

                  (1) the Company could have incurred at least $1.00 of
               additional Indebtedness (other that Permitted Indebtedness)

                  (2) no Default or Event of Default shall have occurred and be

Company of each Board Resolution adopted under this provision, together with a
copy of each such Board Resolution adopted.

                                    THE NOTES

Section 2.01.     FORM AND DATING.

                  The Initial Notes and the Trustee's certificate of
authentication relating thereto shall be substantially in the form of EXHIBIT A
hereto. The Exchange Notes and the Trustee's certificate of authentication
relating thereto shall be substantially in the form of EXHIBIT B hereto. The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or Depository rule or usage. The form of the Notes and any
notation, legend or endorsement on them shall be satisfactory to both the
Company and the Trustee. Each Note shall be dated the date of its issuance and
shall show the date of its authentication.

                  The terms and provisions contained in the Notes, annexed
hereto as EXHIBITS A and B, shall constitute, and are hereby expressly made, a
part of this Indenture and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

                  The Notes shall be issued initially in the form of two or more
permanent global Notes (the "GLOBAL NOTES"). Notes offered and sold (i) in
reliance on Rule 144A shall be issued initially in the form of one or more
permanent Global Notes in registered form, substantially in the form set forth
in EXHIBIT A (the " RULE 144A GLOBAL NOTE") and (ii) in offshore transactions in
reliance on Regulation S shall be issued initially in the form of one or more
permanent global Notes in registered form, substantially in the form set forth
in Exhibit A (the "REGULATION S GLOBAL NOTE"), and in each case shall be
deposited with the Trustee, as custodian for the Depository, duly executed by
the Company and authenticated by the Trustee as hereinafter provided. The
aggregate principal amount of any Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
the Depository, as hereinafter provided.

Section 2.02.     EXECUTION AND AUTHENTICATION.

                  The Notes shall be executed on behalf of the Company by two
Officers of the Company or an Officer and the Secretary or Assistant Secretary
of the Company. Such signature may be either manual or facsimile. The Company's
seal may be impressed, affixed, imprinted or reproduced on the Notes and may be
in facsimile form.

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

<PAGE>
                                      -29-

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

                  The Trustee or an authentication agent (the "AUTHENTICATING
AGENT") shall authenticate (i) Initial Notes for original issue on the date of
this Indenture in the aggregate principal amount not to exceed $150,000,000 and
(ii) Exchange Notes from time to time for issue only in exchange for a like
principal amount of Initial Notes, in each case upon written orders of the
Company in the form of an Officers' Certificate. The Officers' Certificate shall
specify the amount of Notes to be authenticated, the date on which the Notes are
to be authenticated and the aggregate principal amount of Notes outstanding on
the date of authentication, whether the Notes are to be Initial Notes or
Exchange Notes, and shall further specify the amount of such Notes to be issued
as the Global Note or Certificated Notes. The aggregate principal amount of
Notes outstanding at any time may not exceed such amount, except as provided in
Section 2.07.

                  Notwithstanding the foregoing, all Notes issued under this
Indenture shall vote and consent together on all matters (as to which any of
such Notes may vote or consent) as one class and no series of Notes will have
the right to vote or consent as a separate class on any matter.

                  The Trustee, at the expense of the Company, may appoint an
Authenticating Agent to authenticate Notes. Any such appointment shall be
evidenced by an instrument signed by a Responsible Officer, a copy of which
shall be furnished to the Company. 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 right as an Agent to deal with the
Company and Affiliates of the Company.

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

Section 2.03.     REGISTRAR AND PAYING AGENT.

                  The Company shall maintain an office or agency where Notes may
be presented for registration of transfer or for exchange ("REGISTRAR"), an
office or agency located in the Borough of Manhattan, City of New York, State of
New York where Notes may be presented for payment ("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. The Registrar shall keep a register of
the Notes and of their transfer and exchange. The Registrar shall provide the
Company a current copy of such register from time to time upon request of the
Company. The Company may have one or more co-Registrars and one or more
additional Paying Agents. Neither the Company nor any Affiliate of the Company
may act as Paying Agent. The Company may change any Paying Agent, Registrar or
co-Registrar without notice to any Noteholder.

                  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 notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or agent for service of notices and
demands, or fails to give the foregoing notice, the Trustee shall act as such.
The Company initially appoints the Trustee as Registrar, Paying Agent and agent
for service of notices and demands in connection with the Notes.

<PAGE>
                                      -30-

Section 2.04.     PAYING AGENT TO HOLD ASSETS IN TRUST.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that each Paying Agent shall hold in trust for the
benefit of the Holders or the Trustee all assets held by the Paying Agent for
the payment of principal of, premium, if any, or interest on Notes (whether such
assets have been distributed to it by the Company or any other obligor on the
Notes), and shall promptly notify the Trustee in writing of any Default in
making any such payment. The Company at any time may require a Paying Agent to
distribute all assets held by it to the Trustee and account for any assets
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
forthwith distribute to the Trustee all assets so held in trust by such Paying
Agent together with a complete accounting of such sums. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent shall have no further liability for such assets.

Section 2.05.     NOTEHOLDER LISTS.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, the Company shall
furnish or cause the Registrar to furnish to the Trustee on or before each and
in each year, and at such other times as the Trustee may request in writing, a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Holders which list may be conclusively relied on by
the Trustee.

Section 2.06.     TRANSFER AND EXCHANGE.

                  Subject to the provisions of Sections 2.15 and 2.16, when
Notes are presented to the Registrar or a co-Registrar with a written request to
register the transfer of such Notes or to exchange such Notes for an equal
principal amount of Notes of other authorized denominations of the same series,
the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its requirements for such transaction are met; PROVIDED,
HOWEVER, that the Notes presented or surrendered for registration of transfer or
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Registrar or co-Registrar,
duly executed by the Holder thereof or his attorney duly authorized in writing.
To permit registrations of transfer and exchanges, the Company shall execute and
the Trustee shall authenticate Notes at the Registrar's or co-Registrar's
request. No service charge shall be made for any registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
transfer tax or similar governmental charge in connection therewith payable by
the transferor of such Notes (other than any such transfer taxes or similar
governmental charge payable upon exchanges or transfers pursuant to Section
2.10, 3.06, 4.13, 4.17, 4.24 or 9.06, in which event the Company shall be
responsible for the payment of such taxes).

                  The Registrar or co-Registrar shall not be required to
register the transfer of or exchange of any Note (i) during a period beginning
at the opening of business 15 days before the mailing of a notice of redemption
of Notes and ending at the close of business on the day of such mailing and (ii)
selected for redemption in whole or in part pursuant to Article 3, except the
unredeemed portion of any Note being redeemed in part.

                  Any Holder of a Global Note shall, by acceptance of such
Global Note, agree that transfers of beneficial interests in such Global Notes
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.

                                      -31-

Section 2.07.     REPLACEMENT NOTES.

                  If a mutilated Note is surrendered to the Trustee or if the
Holder presents evidence to the satisfaction of the Company and the Trustee that
the Note has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Note. An indemnity bond may be
required by the Company or the Trustee that is sufficient in the judgment of the
Company and the Trustee to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Note is replaced. In every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
to the Trustee evidence to their satisfaction of the destruction, loss or the
theft of such Note and the ownership thereof. Each of the Company and the
Trustee may charge for its expenses (including without limitation attorneys'
fees and expenses) in replacing a Note. In the event any such mutilated, lost,
destroyed or wrongfully taken Note has become due and payable, the Company in
its discretion may pay such Note instead of issuing a new Note in replacement
thereof. The provisions of this Section 2.07 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to replacement
or payment of mutilated, lost, destroyed or wrongfully taken Notes.

                  Every replacement Note is an additional Obligation of the
Company.

Section 2.08.     OUTSTANDING NOTES.

                  Notes outstanding at any time are all Notes authenticated by
the Trustee except for those cancelled by it, those delivered to it for
cancellation, and those described in this Section 2.08 as not outstanding.

                  If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding until
the Company and the Trustee receive proof satisfactory to each of them that the
replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.07.

                  If on a Redemption Date or the Maturity Date, the Paying Agent
holds U.S. legal tender sufficient to pay all of the principal and interest due
on the Notes payable on that date and is not prohibited from paying such money
to the Holders thereof pursuant to the terms of this Indenture, then on and
after that date such Notes cease to be outstanding and interest on them ceases
to accrue.

Section 2.09.     TREASURY NOTES.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver, consent or notice,
Notes owned by the Company or any of its Affiliates shall be considered as
though they are not outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Notes which a Responsible Officer of the Trustee actually knows
are so owned shall be so considered. The Company shall notify the Trustee, in
writing, when it or any of its Affiliates repurchases or otherwise acquires
Notes, of the aggregate principal amount of such Notes so repurchased or
otherwise acquired.

Section 2.10.     TEMPORARY NOTES.

                  Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without

                                      -32-

unreasonable delay, the Company shall prepare and the Trustee shall authenticate
upon receipt of a written order of the Company pursuant to Section 2.02
definitive Notes in exchange for temporary Notes.

Section 2.11.     CANCELLATION.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee, or at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel and, at the written direction of the
Company, dispose of and deliver evidence of such disposal of all Notes
surrendered for registration of transfer, exchange, payment or cancellation.
Subject to Section 2.07, the Company may not issue new Notes to replace Notes
that it has paid or delivered to the Trustee for cancellation. If the Company
shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Notes unless
and until the same are surrendered to the Trustee for cancellation pursuant to
this Section 2.11.

Section 2.12.     DEFAULTED INTEREST.

                  The Company shall pay interest on overdue principal (including
post-petition interest in a proceeding under Bankruptcy Law) at the rate of
interest then borne by the Notes. The Company shall, to the extent lawful, pay
interest on overdue installments of interest (without regard to any applicable
grace periods) at the rate of interest then borne by the Notes.

                  If the Company defaults in a payment of interest on the Notes,
it shall 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, which date shall be the fifteenth day next preceding the
date fixed by the Company for the payment of defaulted interest or the next
succeeding Business Day if such date is not a Business Day. At least 15 days
before the subsequent special record date, the Company shall mail to each
Holder, as of a recent date selected by the Company, with a copy to the Trustee,
a notice that states the subsequent special record date, the payment date and
the amount of defaulted interest, and interest payable on such defaulted
interest, if any, to be paid.

                  Notwithstanding the foregoing, any interest which is paid
prior to the expiration of the 30-day period set forth in Section 6.01(b) shall
be paid to Holders as of the Record Date for the Interest Payment Date for which
interest has not been paid.

Section 2.13.     DEPOSIT OF MONEYS.

                  Prior to 10:00 a.m., New York City time, on each Interest
Payment Date, Redemption Date, Change of Control Payment Date, Excess Proceeds
Payment Date and Maturity Date, the Company shall have deposited with the Paying
Agent in immediately available funds U.S. legal tender sufficient to make
payments, if any, due on such Interest Payment Date, Redemption Date, Change of
Control Payment Date, Excess Proceeds Payment Date or Maturity Date, as the case
may be, in a timely manner which permits the Trustee to remit payment to the
Holders on such Interest Payment Date, Redemption Date, Change of Control
Payment Date, Excess Proceeds Payment Date or Maturity Date, as the case may be.
The principal and interest on Global Notes shall be payable to the Depository or
its nominee, as the case may be, as the sole registered owner and the sole
holder of the Global Notes represented thereby. The principal and interest on
Notes in certificated form shall be payable at the office of the Paying Agent.

Section 2.14.     CUSIP NUMBER.

                  The Company in issuing the Notes may use one or more "CUSIP"
numbers, and if so, the Trustee shall use such CUSIP numbers in notices of
redemption or exchange as a convenience to Holders; PROVIDED that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP numbers printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes. The Company shall promptly notify the Trustee in writing of any change in
the CUSIP number.

Section 2.15.     BOOK-ENTRY PROVISIONS FOR GLOBAL NOTES.

Depository may be treated by the Company, the Trustee and any agent of the

whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Agent Members, the
operation of customary practices governing the exercise of the rights of a

procedures of the Depository and the provisions of Section 2.16. In addition,

Global Note or (y) has ceased to be a clearing company registered under the
Exchange Act and, in each case, a successor depositary is not appointed by the
Company within 90 days of such notice, (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Certificated
Notes, or (iii) a Default or an Event of Default has occurred and is continuing
and the Registrar has received a written request from the Depository to issue

                  (c) In connection with any transfer or exchange of a
portion of the beneficial interest in any Global Note to beneficial owners
pursuant to paragraph (b), the Registrar shall (if one or more Certificated
Notes are to be issued) reflect on its books and records the date and a decrease
in the principal amount of the Global Note in an amount equal to the principal
amount of the beneficial interest in the Global Note to be transferred, and the
Company shall execute, and the Trustee shall upon receipt of a written order
from the Company authenticate and make available for delivery, one or more
Certificated Notes of like tenor and amount.

                  (d) In connection with the transfer of Global Notes as an
entirety to beneficial owners pursuant to paragraph (b), the Global Notes shall
be deemed to be surrendered to the Trustee for cancellation, and the Company
shall execute, and the Trustee shall, upon receipt of an authentication order
from the Company in the form of an Officers' Certificate, authenticate and
deliver, to each beneficial owner identified by the Depository in writing in
exchange for its beneficial interest in the Global Notes, an equal aggregate
principal amount of Certificated Notes of authorized denominations.

Section 3.01.     NOTICES TO TRUSTEE.

                  If the Company elects to redeem Notes pursuant to paragraph 7
of the Notes, at least 60 days prior to the Redemption Date or during such other
period as the Trustee may agree to, the Company shall notify the Trustee in
writing of the Redemption Date, the principal amount of Notes to be redeemed and
the Redemption Price, and deliver to the Trustee an Officers' Certificate
stating that such redemption will comply with the conditions contained herein
and in the Notes, as appropriate.

Section 3.02.     SELECTION OF NOTES TO BE REDEEMED.

                  In the event that less than all of the Notes are to be
redeemed at any time, selection of the Notes to be redeemed shall be made by the
Trustee in compliance with the requirements of the principal securities
exchange, if any, on which such Notes are listed or, if such Notes are not then
listed on a national securities exchange, on a PRO RATA basis, by lot or by such
other method as the Trustee shall deem fair and appropriate; PROVIDED, HOWEVER,
that no Notes of a principal amount of $1,000 or less shall be redeemed in part;
PROVIDED, FURTHER, that if a partial redemption is made with the proceeds of any
Public Equity Offering, selection of the Notes or portions thereof for
redemption shall be made by the Trustee only on a PRO RATA basis or on as nearly
a PRO RATA basis as is practicable (subject to the procedures of the
Depository), unless such method is otherwise prohibited. The Trustee shall
promptly notify the Company of the Notes selected for redemption and, in the
case of any Notes selected for partial redemption, the principal amount thereof
to be redeemed.

Section 3.03.     NOTICE OF REDEMPTION.

                  Notice of redemption shall be mailed by first class mail at
least 30 but not more than 60 calendar days before the Redemption Date to each
Holder of Notes to be redeemed at its registered address. If any Note is to be
redeemed in part only, the notice of redemption that relates to such Note shall
state the portion of the principal amount thereof to be redeemed.

                  The notice shall identify the Notes to be redeemed (including
the CUSIP number(s) thereof) and shall state:

                  (1)  the Redemption Date;

                  (2) the Redemption Price and the amount of accrued interest,
if any, to be paid;

                  (3) 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 issued;

<PAGE>
                                      -40-

                  (4) the name, address and telephone number of the Paying
         Agent;

                  (5) that Notes called for redemption must be surrendered to
         the Paying Agent at the address specified to collect the Redemption
         Price plus accrued interest, if any;

                  (6) that, unless the Company defaults in its obligation to
         deposit U.S. legal tender with the Paying Agent in accordance with
         Section 3.05 hereof, interest on Notes called for redemption ceases to
         accrue on and after the Redemption 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;

                  (7) the subparagraph of the Notes pursuant to which the Notes
         called for redemption are being redeemed; and

                  (8) if fewer than all the Notes are to be redeemed, the
         identification of the particular Notes (or portion thereof) to be
         redeemed, as well as the aggregate principal amount of Notes to be
         redeemed and the aggregate principal amount of Notes to be outstanding
         after such partial redemption.

Section 3.04.     EFFECT OF NOTICE OF REDEMPTION.

                  Once the notice of redemption described in Section 3.03 is
mailed, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price, including any premium, plus accrued interest
to the Redemption Date, if any. Upon surrender to the Paying Agent, such Notes
shall be paid at the Redemption Price, including any premium, plus accrued
interest to the Redemption Date, if any; PROVIDED that if the Redemption Date is
after a Record Date and on or prior to the Interest Payment Date, the accrued
interest shall be payable to the Holder of the redeemed Notes registered on the
relevant Record Date.

Section 3.05.     DEPOSIT OF REDEMPTION PRICE.

                  On or prior to 10:00 a.m., New York City time, on each
Redemption Date, the Company shall have deposited with the Paying Agent in
immediately available funds U.S. legal tender sufficient to pay the Redemption
Price of and accrued interest on all Notes to be redeemed on that date. The
Paying Agent shall promptly return to the Company any U.S. legal tender so
deposited that is not required for that purpose upon the written request of the
Company.

                  On and after any Redemption Date, if U.S. legal tender
sufficient to pay the Redemption Price of and accrued interest on Notes called
for redemption shall have been made available in accordance with the preceding
paragraph, the Notes called for redemption will cease to accrue interest and the
only right of the Holders of such Notes will be to receive payment of the
Redemption Price of and, subject to the first proviso in Section 3.04, accrued
and unpaid interest on such Notes to the Redemption Date. If any Note called for
redemption shall not be so paid, interest will continue to accrue and be paid,
from the Redemption Date until such redemption payment is made, on the unpaid
principal of the Note and any interest not paid on such unpaid principal, in
each case, at the rate and in the manner provided for in Section 2.12.

Section 3.06.     NOTES REDEEMED IN PART.

                  Upon surrender of a Note that is redeemed in part, the Company
shall execute and the Trustee shall authenticate for a Holder a new Note or
Notes equal in principal amount to the unredeemed portion of the Note
surrendered.

Section 4.03.     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 (as a defense or

premium, if any, and/or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture; and (to the extent it may

<PAGE>
                                      -42-

describing all or such Defaults or Events of Default of which he or she may have
knowledge and what action the Company is taking or proposes to take with respect
thereto) and that to the best of his or her knowledge no event has occurred and

take with respect thereto. The Officers' Certificate shall also notify the
Trustee should the Company elect to change the manner in which it fixes its
fiscal year end.

Subsidiary and the material rights (charter and statutory), licenses and
franchises of the Company and its Subsidiaries except where the failure to
preserve and keep in full force and effect any such rights, licenses and
franchise shall not have a material adverse effect on the financial condition,
business or results of operations or prospects of the Company and its
Subsidiaries taken as a whole; and PROVIDED that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,
limited liability company, partnership or other existence of any of its
Subsidiaries, if the Board of Directors of the Company shall determine that the

the Company and its Subsidiaries, taken as a whole, and that the loss thereof is
not adverse in any material respect to the Holders.

notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall 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,

thereof, and of any governmental department, commission, board, regulatory
authority, bureau, agency and instrumentality of the foregoing, in respect of
the conduct of their respective businesses and the ownership of their respective

excepted) and supplied with all necessary equipment and shall cause to be made
all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in its judgment may be necessary, so that the business carried

times; PROVIDED, HOWEVER, that nothing in this Section 4.09 shall prevent the
Company or any of its Subsidiaries 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 Board of Directors of the
Company or of the Board of Directors of the Subsidiary of the Company concerned,
or of an Officer (or other agent employed by the Company or of any of its
Subsidiaries) of the Company or any of its Subsidiaries having managerial
responsibility for any such property, desirable in the conduct of the business

Subsidiaries to maintain, insurance with carriers believed by the Company to be
responsible against such risks and in such amounts, and with such deductibles,
retentions, self-insured amounts and co-insurance provisions, as are customarily
carried by similar businesses of similar size, including property and casualty
loss, workers' compensation and interruption of business insurance.

Section 4.10.     LIMITATION ON ADDITIONAL INDEBTEDNESS.

                  (A) The Company will not, and will not permit any of the
Restricted Subsidiaries to, directly or indirectly, incur (as defined) any
Indebtedness (including Acquired Indebtedness); PROVIDED that if no Default or
Event of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of such Indebtedness, the Company may incur
Indebtedness (including Acquired Indebtedness) if after giving effect to the
incurrence of such Indebtedness and the receipt and application of the proceeds
thereof, the Company's Consolidated Fixed Charge Coverage Ratio is greater than
or equal to 2.0 to 1.

                  (B) Notwithstanding the foregoing, the Company and, to the
extent applicable, the Restricted Subsidiaries may incur Permitted Indebtedness;
PROVIDED that the Company will not incur any Permitted Indebtedness that ranks
junior in right of payment to the Notes that has a maturity or mandatory sinking
fund payment prior to the maturity of the Notes. Notwithstanding any other
provisions of this Section 4.10, (i) the maximum amount of Indebtedness that the
Company or a Restricted Subsidiary may incur pursuant to this covenant shall not
be deemed to be exceeded, with respect to any outstanding Indebtedness, due
solely to the result of fluctuations in the exchange rates of currencies and
(ii) in the event that an item of Indebtedness meets the criteria of more than
one of the categories of Permitted Indebtedness, the Company may, in its sole
discretion, classify (or reclassify) such item of Indebtedness in any manner
that complies with this covenant and such items of Indebtedness will be treated
as having been incurred pursuant to only one of such categories. Accrual of
interest, accretion or amortization of original discount and the payment of
interest in the form of additional Indebtedness will not be deemed to be an
incurrence of Indebtedness for purposes of this Section and accruals of
dividends or the payment of dividends on Disqualified Capital Stock in the form
of additional shares of the same class of Disqualified Capital Stock will not be
deemed an issuance of Disqualified Capital Stock for purposes of this Section.

         continuing at the time of or immediately after giving effect to such

         Restricted Payment, the Company could incur $1.00 of additional
         Indebtedness (other than Permitted Indebtedness) under Section 4.10;
         and

                  (3) immediately after giving effect to such Restricted
         Payment, the aggregate of all Restricted Payments declared or made
         after the Issue Date does not exceed the sum of

                           (a) 50% of the Company's Cumulative Consolidated Net
                  Income (or minus 100% of any cumulative deficit in
                  Consolidated Net Income during such period),

                           (b) 100% of the aggregate Net Proceeds received by
                  the Company from the issue or sale after the Issue Date of

                           such Restricted Subsidiary, as the case may be,
                           elects, or is required, to prepay, repay or purchase
                           Indebtedness under any then existing Senior

                                            (ii) the Asset Sale Proceeds so
                                    contractually committed are so applied
                                    within 360 days following the receipt of
                                    such Asset Sale Proceeds; and

                           equal to 100% of the principal amount thereof plus
                           accrued and unpaid interest, if any, to the purchase
                           date (an "Excess Proceeds Offer"). If an Excess
                           Proceeds Offer is not fully subscribed, the Company
                           may retain the portion of the Available Asset Sale
                           Proceeds not required to repurchase Notes and use

Company or such Restricted Subsidiary may temporarily reduce Indebtedness under
a revolving credit facility, if any, or otherwise invest such Asset Sale
Proceeds in Cash Equivalents.

                   (5) that Holders accepting the offer to have their Notes
         purchased pursuant to an Excess Proceeds Offer will be required to

         surrendered by Holders exceeds the amount of Excess Proceeds, Company
         shall select the Notes to be purchased on a PRO RATA basis (with such
         adjustments as may be deemed appropriate by the Company so that only
         Notes in denominations of $1,000 or integral multiples thereof, shall
         be purchased);

                   (8) that Holders whose Notes are being purchased only in part

thereunder to the extent such laws and regulations are applicable in connection

         as favorable as the terms that could be obtained by the Company or
         such Restricted Subsidiary, as the case may be, in a comparable
         transaction made on an arm's-length basis between unaffiliated
         parties.

                  In any Affiliate Transaction (or any series of related
Affiliate Transactions that are similar or part of a common plan) involving an
amount or having a fair market value in excess of $2.5 million that is not
permitted under clause (1) above, the Company must obtain a Board Resolution
certifying that such Affiliate Transaction complies with clause (2) above. In
any Affiliate Transaction (or any series of related Affiliate Transactions that
are similar or part of a common plan) involving an amount or having a fair
market value in excess of $5.0 million that is not permitted under clause (1)
above, the Company must obtain a favorable written opinion as to the fairness of
such transaction or transactions, as the case may be, from an Independent
Financial Advisor.

                  (B) The foregoing provisions will not apply to

                                      -51-

                  (1) any Restricted Payment that is not prohibited by the
         provisions described under Section 4.11 or any Permitted Investment;

                  (2) reasonable fees and compensation paid to and indemnity
         provided on behalf of, officers, directors or employees of the Company
         or any Restricted Subsidiary as determined in good faith by the
         Company's Board of Directors or senior management;

                  (3) any agreement as in effect as of the Issue Date or any
         amendment thereto or any transaction contemplated thereby (including
         pursuant to any amendment thereto) in any replacement agreement
         thereto so long as any such amendment or replacement agreement is not
         more disadvantageous to the holders in any material respect than the
         original agreement as in effect on the Issue Date;

                  (4) any transaction permitted under Section 5.01; or

                  (5) transactions with Affiliates solely in their capacity as
         holders of Indebtedness or Capital Stock of the Company or any of its
         Subsidiaries where such Affiliates are treated no more favorably than
         holders of such Indebtedness or such Capital Stock generally.

Section 4.15.     LIMITATIONS ON LIENS.

                  (A) The Company will not, and will not permit any Restricted
Subsidiary to, create, incur or otherwise cause or suffer to exist or become
effective any Liens of any kind (other than Permitted Liens) upon any property
or asset of the Company or any of the Restricted Subsidiaries or any shares of
Capital Stock or Indebtedness of any Restricted Subsidiary that owns property or
assets, now owned or hereafter acquired, unless

                  (1) if such Lien secures Indebtedness that ranks equally with
         the Notes, then the Notes are secured on an equal and ratable basis
         with the obligations so secured until such time as such obligation is
         no longer secured by a Lien or

                  (2) if such Lien secures Indebtedness that is subordinated to
         the Notes, any such Lien shall be subordinated to the Lien granted to
         the holders of the Notes to the same extent as such Indebtedness is
         subordinated to the Notes.

Section 4.16.     LIMITATIONS ON INVESTMENTS.

                  The Company will not, and will not permit any Restricted
Subsidiary to, make any Investment other than

                  (1) a Permitted Investment or

                  (2) an Investment that is made after the Issue Date as a
         Restricted Payment in compliance with Section 4.11.

         payment;

                  (3) that any Note not tendered will continue to accrue
         interest;

                  (4) that, unless the Company defaults in the payment of the

         pursuant to the Change of Control Offer shall cease to accrue interest
         after the Change of Control Payment Date;

                  (5) that Holders accepting the offer to have their Notes
         purchased pursuant to a Change of Control Offer will be required to
         surrender the Notes, with the form entitled "Option of Holder to Elect
         Purchase" on the reverse of the Note completed to the Paying Agent at
         the address specified in the notice prior to the close of business on
         the Business Day preceding the Change of Control Payment Date;

                  (6) that Holders will be entitled to withdraw their acceptance
         if the Paying Agent receives, not later than the close of business on
         the third Business Day preceding the Change of Control Payment Date, a
         telegram, facsimile transmission or letter setting forth the name of
         the Holder, the principal amount of the Notes delivered for purchase,
         and a statement that such Holder is withdrawing his election to have
         such Notes purchased;

                  (7) that Holders whose Notes are being purchased only in part
         will be issued new Notes equal in principal amount to the unpurchased
         portion of the Notes surrendered;

                  (8) any other procedures that a Holder must follow to accept a

         pursuant to the Change of Control Offer;

                  (2) deposit with the Paying Agent money sufficient to pay the

                  (C) If the Senior Credit Facility is in effect, or any amounts
are owing thereunder or in respect thereof, at the time of the occurrence of a
Change of Control, prior to the mailing of the notice to Holders described in
the second preceding paragraph, but in any event within 20 days following any
Change of Control, the Company covenants to

                  (1) repay in full all obligations and terminate all
         commitments under or in respect of the Senior Credit Facility and all
         other Senior Indebtedness the terms of which require repayment upon a
         Change of Control or offer to repay in full all obligations and
         terminate all commitments under or in respect of the Senior Credit
         Facility and all such Senior Indebtedness and repay the Indebtedness

         Facility and all such other Senior Indebtedness to permit the
         repurchase of the Notes as described above.

                  The Company must first comply with the covenant described in
the preceding sentence before it shall be required to purchase Notes in the
event of a Change of Control; PROVIDED that the Company's failure to comply with
the covenant described in the preceding sentence constitutes an Event of Default
described in clause (C) under Section 6.01 if not cured within 60 days after the
notice required by such clause.

                  (D) (1) If the Company or any Restricted Subsidiary has issued
any (a) outstanding Indebtedness that is subordinated in right of payment to the
Notes or (b) Preferred Stock, and the Company or such Restricted Subsidiary is
required to make a Change of Control Offer or to make a distribution with
respect to such subordinated Indebtedness or Preferred Stock in the event of a
Change of Control, the Company shall not consummate any such offer or
distribution with respect to such subordinated Indebtedness or Preferred Stock
until such time as the Company shall have paid the Change of Control Purchase
Price in full to the Holders of Notes that have accepted the Company's Change of
Control Offer and shall otherwise have consummated the change of control offer
made to Holders and

                  (2) the Company will not issue Indebtedness that is
subordinated in right of payment to the Notes or Preferred Stock with change of
control provisions requiring the payment of such Indebtedness or Preferred Stock
prior to the payment of the Notes in the event of a Change in Control under this
Indenture.

                   (E) The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of Notes pursuant to a Change of Control Offer. To the
extent that the provisions of any securities laws or regulations conflict with
this Section 4.17, the Company shall comply with the applicable securities laws
and regulations and shall not be deemed to have breached its obligations under
this Section 4.17 by virtue thereof.

related transactions, to any Person unless:

                  (1) the Company shall be the continuing Person, or the Person
          (if other than the Company) formed by such consolidation or into which

increased thereby and that the successor assumes all obligations of the Company
or such Restricted Subsidiary, as the case may be, under this Indenture, the
Notes and the Registration Rights Agreement.

                  For purposes of the foregoing, the transfer (by lease,
assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all of the properties or assets of one or
more Restricted Subsidiaries of the Company the Capital Stock of which
constitutes all or substantially all of the properties and assets of the Company
shall be deemed to be the transfer of all or substantially all of the properties
and assets of the Company.

                  Each Guarantor (other than any Guarantor whose Guarantee is to
be released in accordance with the terms of the Guarantee and the Indenture in
connection with any transaction complying with Section 4.13) will not, and the
Company will not cause or permit any Guarantor to, consolidate with or merge
with or into any Person other than the Company or any other Guarantor unless:

                  (1) the entity formed by or surviving any such consolidation
          or merger (if other than the Guarantor) or to which such sale, lease,
          conveyance or other disposition shall have been made is a corporation
          or limited liability company organized and existing under the laws of
          the United States or any State thereof or the District of Columbia;

                  (2) such entity assumes by supplemental indenture all of the
          obligations of the Guarantor on the Guarantee;

                  (3) immediately after giving effect to such transaction, no
          Default or Event of Default shall have occurred and be continuing; and

                  (4) immediately after giving effect to such transaction and
          the use of any net proceeds therefrom on a PRO FORMA basis, the
          Company could satisfy the provisions of clause (3) of the first
          paragraph of this Section;

                  PROVIDED, HOWEVER, that the foregoing provision shall not
apply in the case of the merger of a Guarantor with another person in a
transaction that constitutes an Asset Sale.

                  Any merger or consolidation of a Guarantor with and into the
Company (with the Company being the surviving entity) or another Guarantor that
is a Restricted Subsidiary of the Company need only comply with clause (4) of
the first paragraph of this Section.

                  Nothing in this Section shall be deemed to prevent the
consummation of the Merger or the conversion of the Company's domestic
Restricted Subsidiaries into limited liability companies immediately following
consummation of the Merger.

Section 5.02.     SUCCESSOR PERSON SUBSTITUTED.

                  Upon any consolidation, merger, conveyance or any transfer of
all or substantially all of the assets of the Company in accordance with Section
5.01 above, the successor entity formed by such consolidation or into which the
Company or any such Restricted Subsidiary is merged or to which such transfer is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Company or such Restricted Subsidiary, as the case may be, under
this Indenture with the same effect as if such successor entity had been named
as the Company or such Restricted Subsidiary, as the case may be, herein, and
thereafter the predecessor entity shall be relieved of all obligations and
covenants under this Indenture and the Notes.

         premium, if any, on the Notes whether at maturity, upon redemption
         (including the failure to make a payment to purchase notes pursuant to
         a Change of Control Offer or an Excess Proceeds Offer) or otherwise
         (whether or not such payment shall be prohibited by Article 10 or
         Article 11);

                  (b) there is a default for 30 days in payment of any interest

         Subsidiary in the observance or performance of any other covenant in

         amount of the Notes then outstanding (except in the case of a default
         with respect to Section 4.17 or Section 5.01, which shall constitute an
         Event of Default with such notice requirement but without such passage
         of time requirement);

                  (d) there is a failure to pay when due principal, interest or
         premium with respect to any Indebtedness of the Company or any

         failure to pay principal at the final maturity thereof, shall not be
         cured, waived or postponed pursuant to an agreement with the holders of
         such Indebtedness within 60 days after written notice to the Company by
         the Trustee or any Holder, or the acceleration of any such
         Indebtedness, which acceleration shall not be rescinded or annulled
         within 20 days after written notice to the Company by the Trustee or
         any Holder, if the aggregate amount of such Indebtedness, together with
         the amount of any other such Indebtedness in default for failure to pay
         principal, interest or premium or that has been accelerated, aggregates
         $7,500,000 or more at any time;

                  (e) any final judgment or judgments not fully covered by
         insurance that can no longer be appealed for the payment of money in

         Restricted Subsidiary thereof, and shall not be discharged for any
         period of 60 consecutive days during which a stay of enforcement shall
         not be in effect;

official under any Bankruptcy Law.

Section 6.02.     ACCELERATION.

                  If an Event of Default (other than an Event of Default of the
type described in Section 6.01(f) or (g)) shall have occurred and be continuing,
then the Trustee or the Holders of not less than 25% in aggregate principal
amount of the Notes then outstanding may declare to be immediately due and
payable the entire principal amount of all the Notes then outstanding plus
accrued interest to the date of acceleration and (1) the same shall become
immediately due and payable or (2) if there are any amounts outstanding under
the Senior Credit Facility, the same shall become immediately due and payable
upon the first to occur of an acceleration under the Senior Credit Facility and
five Business Days after receipt by the Company and the representative under the
Senior Credit Facility of a notice of acceleration; PROVIDED, HOWEVER, that
after such acceleration but before a judgment or decree based on such
acceleration is obtained by the Trustee, the Holders of a majority in aggregate
principal amount of outstanding Notes may rescind and annul such acceleration
if:

                  (1) all Events of Default, other than nonpayment of principal,
         premium, if any, or interest that has become due solely because of the
         acceleration, have been cured or waived;

<PAGE>
                                      -61-

                  (2) to the extent the payment of such interest is lawful,
         interest on overdue installments of interest and overdue principal,
         which has become due otherwise than by such declaration of
         acceleration, has been paid;

                  (3) if the Company has paid the Trustee its reasonable
         compensation and reimbursed the Trustee for its expenses, disbursements
         and advances; and

                  (4) in the event of the cure or waiver of an Event of Default
         of the type described in Section 6.01(f) or (g) above, the Trustee
         shall have received an Officers' Certificate and an Opinion of Counsel
         that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto. In case an Event of Default with respect to the Company of
the type described in Section 6.01(f) or (g) above shall occur, the principal,
premium and interest amount with respect to all of the Notes shall be due and
payable immediately without any declaration or other act on the part of the
Trustee or the Holders.

Section 6.03.     OTHER REMEDIES.

                  If an Event of Default occurs and is continuing, the Trustee,
in its own name or as trustee of an express trust, may pursue any available
remedy by proceeding at law or in equity to collect the payment of principal of,
or premium, if any, and interest on the Notes or to enforce the performance of
any provision of the Notes or this Indenture and may take any necessary action
requested of it as Trustee to settle, compromise, adjust or otherwise conclude
any proceedings to which it is a party.

                  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. A
delay or omission by the Trustee or any Noteholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative to the
extent permitted by law.

Section 6.04.     WAIVER OF PAST DEFAULTS AND EVENTS OF DEFAULT.

                  Subject to Sections 2.09, 6.02, 6.07 and 8.02, the Holders of
a majority in aggregate principal amount of the Notes then outstanding have the
right, on behalf of all Holders, to waive any past or existing Default or
compliance with any provision under this Indenture EXCEPT a Default in the
payment of the principal of, or interest or premium, if any, on any Note as
specified in clauses (a) and (b) of Section 6.01 or in respect of a covenant or
a provision that cannot be modified or amended without the consent of all
Holders as provided for in Section 8.02. The Company shall deliver to the
Trustee an Officers' Certificate stating that the requisite percentage of
Holders have consented to such waiver and providing evidence reasonably
satisfactory to the Trustee of such consents. In case of any such waiver, the
Company, the Trustee and the Holders shall be restored to their former positions
and rights hereunder and under the Notes, respectively. This paragraph of this
Section 6.04 shall be in lieu of ss. 316(a)(1)(B) of the TIA and such ss.
316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the
Notes, as permitted by the TIA.

                  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.

                  Subject to Section 2.09, the Holders of a majority in
aggregate principal amount of the then outstanding Notes have the right to
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 by this Indenture. The Trustee, however, may refuse to follow any
direction that conflicts with law or this Indenture or that the Trustee
determines may be unduly prejudicial to the rights of another Noteholder not
taking part in such direction, and the Trustee shall have the right to decline
to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Responsible Officer, determine that the
proceedings so directed may involve it in personal liability; PROVIDED that the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. In the event the Trustee takes any action or
follows any direction pursuant to this Indenture, the Trustee shall be entitled
to indemnification satisfactory to it against any loss or expense caused by
taking such action or following such direction. This Section 6.05 shall be in
lieu of ss. 316(a)(1)(A) of the TIA, and such ss. 316(a)(1)(A) of the TIA is
hereby expressly excluded from this Indenture and the Notes, as permitted by the
TIA.

Section 6.06.     LIMITATION ON SUITS.

                  Subject to Section 6.07 below, no Holder has any right to
institute any proceeding with respect to this Indenture or any remedy hereunder
unless:

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

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

                  (3) such Holder or Holders offer to the Trustee indemnity
         satisfactory to the Trustee against any loss, liability or expense
         which may be incurred in compliance with such request;

                  (4) the Trustee fails to institute such proceeding within 60
         days after receipt of such notice and the offer of indemnity; and

                  (5) the Trustee has not received directions inconsistent with
         such written request during such 60-day period by the Holders of a
         majority in aggregate principal amount of the outstanding Notes.

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

Section 6.07.     RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder to receive payment of principal of, or premium, if any, or
accrued interest of any Note held by such Holder on or after the respective due
dates expressed in such Note, or to bring suit for the enforcement of any such
payment on or after such respective dates, is absolute and unconditional and
shall not be impaired or affected without the consent of such Holder.

                                      -63-

Section 6.08.     COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default in payment of principal, premium, if
any, or interest specified in Section 6.01(a) or (b) occurs and is continuing,
the Trustee may recover judgment in its own name and as trustee of an express
trust against the Company for the whole amount of unpaid principal, premium and
accrued interest remaining unpaid, together with, to the extent that payment of
such interest is lawful, interest on overdue principal and interest on overdue
installments of interest, in each case at the rate set forth in Section 4.01,
and such further amounts 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 the
Holders allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Notes), its creditors or its property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after
deduction of its charges and expenses to the extent that any such charges and
expenses are not paid out of the estate in any such proceedings and any
custodian in any such judicial proceeding is hereby authorized by each
Noteholder 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 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 authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Noteholder any plan or 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 Noteholder in any such
proceedings.

Section 6.10.     PRIORITIES.

                  If the Trustee collects any money pursuant to this Article 6,
it shall pay out the money in the following order:

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

                  SECOND:  if the Holders are forced to proceed against the
          Company or any Guarantor directly without the Trustee, to Holders for
          their collection costs;

                  THIRD:  to Holders for amounts due and unpaid on the Notes
          for principal, premium, if any, and interest as to each, ratably,
          without preference or priority of any kind, according to the amounts
          due and payable on the Notes; and

                  FOURTH:  to the Company or, to the extent the Trustee collects
          any amounts from any Guarantor, to such Guarantor.

                  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 in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

                                    ARTICLE 7

                                     TRUSTEE

Section 7.01.     DUTIES OF TRUSTEE.

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

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

                  (1) The Trustee need perform only those duties as are
          specifically set forth in this Indenture and no covenants or
          obligations shall be implied in this Indenture against the Trustee.

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

                  (c) Notwithstanding anything to the contrary herein contained,
          the Trustee may not be relieved from liability for its own negligent
          action, its own negligent failure to act or its own willful
          misconduct, except that:

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

                  (2) The Trustee shall not be liable for any error of judgment
          made in good faith by a Responsible Officer, unless it is conclusively
          determined by a court of competent jurisdiction that the Trustee was
          negligent in ascertaining the pertinent facts.

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

                  (d) No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any liability, financial or
otherwise, in the performance of any of its duties hereunder or

<PAGE>
                                      -65-

to take or omit to take any action under this Indenture or take any action at
the request or direction of Holders if it shall have reasonable grounds for
believing that repayment of such funds is not assured to it or it does not
receive from such Holders an indemnity satisfactory to it against such risk,
liability, loss, fee or expense which might be incurred by it in compliance with
such request or direction.

                  (e) Whether or not herein expressly provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b), (c) and (d) of this Section 7.01.

                  (f) The Trustee shall not be liable for interest on any money
or assets received by it except as the Trustee may agree in writing with the
Company. Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

Section 7.02.     RIGHTS OF TRUSTEE.

                  Subject to Section 7.01:

                  (a) The Trustee may conclusively rely and shall be fully
         protected in acting or refraining from acting upon any officers'
         certificate, opinion of counsel, resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent, order
         or document reasonably believed by it to be genuine and to have been
         signed or presented by the proper Person. The Trustee need not
         investigate any fact or matter stated in the document.

                  (b) Before the Trustee acts or refrains from acting with
         respect to any matters contemplated by this Indenture or the Notes it
         may consult with counsel and may require an Officers' Certificate or an
         Opinion of Counsel, or both, which shall conform to the provisions of
         Section 12.05. The Trustee shall be fully protected and shall not be
         liable for any action it takes or omits to take in good faith in
         reliance on such certificate or opinion.

                  (c) The Trustee may act through attorneys and agents and shall
         not be responsible for the misconduct or negligence of any attorney or
         agent so long as the appointment of such attorney or agent was made
         with due care.

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

                  (e) The Trustee may consult with counsel of its selection, and
         the advice or opinion of such counsel shall be full and complete
         authorization and protection from liability in respect of any action
         taken, omitted or suffered by it hereunder in good faith and in
         accordance with the advice or opinion of such counsel.

                  (f) In no event shall the Trustee be liable for the selection
         of investments or for investment losses thereon. The Trustee shall have
         no liability in respect of losses incurred as a result of the
         liquidation of any investment prior to its stated maturity or the
         failure of the Company to provide timely written instructions.

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 make loans to, accept deposits from,
perform services for or otherwise deal with the Company, or any

<PAGE>
                                      -66-

Affiliates thereof, with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights. The Trustee, however, shall be
subject to Sections 7.10 and 7.11.

Section 7.04.     TRUSTEE'S DISCLAIMER.

                  The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company's use of the proceeds from the sale of
Notes or any money paid to the Company pursuant to the terms of this Indenture
and it shall not be responsible for any statement of the Company in this
Indenture or the Notes other than the Trustee's certificate of authentication.

Section 7.05.     NOTICE OF DEFAULTS.

                  If a Default or an Event of Default occurs and is continuing
and if a Responsible Officer of the Trustee has actual knowledge of such Default
or Event of Default, the Trustee shall mail to each Noteholder notice of the
uncured Default or Event of Default within 30 days after such Default or Event
of Default occurs. Except in the case of a Default or an Event of Default in
payment of principal of, premium or interest on, any Note, including an
accelerated payment and the failure to make payment on the Change of Control
Payment Date pursuant to a Change of Control Offer or on the Excess Proceeds
Payment Date pursuant to an Excess Proceeds Offer and, except in the case of a
failure to comply with Article 5. This Section 7.05 shall be in lieu of the
proviso to Section 315(b) of the TIA, and such proviso of Section 315(b) of the
TIA is hereby expressly excluded from this Indenture and the Notes, as permitted
by the TIA.

Section 7.06.     REPORTS BY TRUSTEE TO HOLDERS.

                  If required by TIA Section 313(a), within 60 days after May 15
of any year, commencing the May 15 following the date of this Indenture, the
Trustee shall mail to each Noteholder a brief report dated as of such May 15
that complies with TIA Section 313(a). The Trustee also shall comply with TIA
Section 313(b), (c) and (d).

                  Reports pursuant to this Section 7.06 shall be transmitted by
mail:

                  (1) to all registered Holders, as the names and addresses of
         such Holders appear on the Registrar's books; and

                  (2) to such Holder as have, within the two years preceding
         such transmission, filed their names and addresses with the Trustee for
         that purpose.

                  A copy of each report at the time of its mailing to Holders
shall be filed with the Commission and each stock exchange, if any, on which the
Notes are listed. 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 from time to time such
compensation as shall be agreed in writing between the Company and the Trustee
for the Trustee's services. The Trustee's compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable fees, disbursements,
advances and expenses, including out-of-pocket expenses incurred or made by it
in connection with the performance of its duties under this Indenture (except
for such

<PAGE>
                                      -67-

expenses as may be attributable to its negligence, bad faith or willful
misconduct as conclusively determined by a court of competent jurisdiction) or
in connection with the collection of any funds. Such expenses shall include the
reasonable fees and expenses of the Trustee's agents, counsel and others not
regularly in its employ.

                  The Company shall indemnify each of the Trustee (in its
capacity as Trustee) and its agents, employees, stockholders and directors and
officers for, and hold them harmless against, any loss, claim, damage, injury,
liability or expense incurred by them except for such actions to the extent
caused by any negligence, bad faith or willful misconduct on their part,
directly or indirectly arising out of or in connection with the administration
of this trust, including the reasonable costs and expenses of defending
themselves against any claim or liability in connection with the exercise or
performance of any of their rights, powers or duties hereunder. The Trustee
shall notify the Company promptly, in writing, of any claim asserted against the
Trustee for which it may seek indemnity. At the Trustee's discretion, the
Company shall defend the claim and the Trustee shall cooperate and may
participate in the defense; PROVIDED that any settlement of a claim shall be
approved in writing by the Trustee. The Company need not pay for any settlement
made without its written consent, which consent shall not be unreasonably
withheld. The Company need not reimburse any expense or indemnify against any
loss or liability to the extent incurred by the Trustee through its negligence,
bad faith or willful misconduct as conclusively determined by a court of
competent jurisdiction.

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

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(f) or (g) occurs, such expenses and
the compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law.

                  The obligation of the Company under this Section 7.07 shall
survive the resignation or removal of the Trustee and the satisfaction and
discharge of this Indenture.

Section 7.08.     REPLACEMENT OF TRUSTEE.

                  The Trustee may resign at any time by so notifying the Company
in writing. The Holders of a majority in aggregate principal amount of the
outstanding Notes may remove the Trustee by so notifying the Trustee and the
Company in writing and may appoint a successor Trustee with the Company's
consent, such consent not to be unreasonably withheld. The Company may remove
the Trustee at its election if:

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

                  (b)      the Trustee is adjudged a bankrupt or an insolvent;

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

                  (d)      the Trustee otherwise 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 Trustee in such event being referred
to herein as the retiring Trustee), the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in aggregate principal amount of the outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

<PAGE>
                                      -68-

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Noteholder.

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

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

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

Section 7.09.     SUCCESSOR TRUSTEE BY CONSOLIDATION, MERGER OR CONVERSION.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, subject to this Article 7, the successor corporation without any
further act shall (if it is otherwise eligible hereunder) be the successor
Trustee.

Section 7.10.     ELIGIBILITY; DISQUALIFICATION.

                  This Indenture shall always have a Trustee which shall be
eligible to act as Trustee under TIA Sections 310(a)(1) and 310(a)(2). The
Trustee shall have a combined capital and surplus of at least $100,000,000 as
set forth in its most recent published annual report of condition. If the
Trustee has or shall acquire any "conflicting interest" within the meaning of
TIA Section 310(b), the Trustee and the Company shall comply with the provisions
of TIA Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities of
the Company are outstanding if the requirements for such exclusion set forth in
TIA Section 310(b)(1) are met. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 7.10, the Trustee
shall resign immediately in the manner and with the effect hereinbefore
specified in this Article 7.

Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                  The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein. The provisions of TIA Section 311 shall apply to the Company
as obligors of the Notes.

                                    ARTICLE 8

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

Section 8.01.     WITHOUT CONSENT OF HOLDERS.

                  The Company and the Guarantors, when authorized by a Board
Resolution, and the Trustee may amend or supplement this Indenture, the Notes or
the Guarantees without notice to or consent of any Noteholder:

                  (1) to cure any ambiguity, defect or inconsistency; PROVIDED
         that such amendment or supplement does not, in the opinion of the
         Trustee, adversely affect the rights of any Holder in any material
         respect;

                  (2) to provide for uncertificated Notes in addition to or in
         place of Certificated Notes;

                  (3)  to comply with Article 5;

                  (4) to comply with any requirements of the Commission in order
         to effect or maintain the qualification of this Indenture under the
         TIA;

                  (5) to make any change that would provide any additional
benefit or rights to the Holders;

                  (6) to make any other change that does not adversely affect
         the rights of any Holder under this Indenture;

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

                  (8)  to secure the Notes pursuant to the requirements of
         Section 4.15 or otherwise; and

                  (9) to reflect the release of a Guarantor from its obligations
         with respect to its Guarantee pursuant to Section 11.05 or to add a
         Guarantor pursuant to Section 4.24.

Section 8.02.     WITH CONSENT OF HOLDERS.

                  Subject to Section 6.07, the Company and the Guarantors, when
each is authorized by a Board Resolution, and the Trustee may amend or
supplement this Indenture, the Notes or the Guarantees with the written consent
of the Holders of at least a majority in aggregate principal amount of the
outstanding Notes. Subject to Section 6.07, the Holders of a majority in
aggregate principal amount of the outstanding Notes may waive compliance by the
Company or any Guarantor with any provision of this Indenture, the Notes or the
Guarantees. However, without the consent of each Noteholder affected, an
amendment, supplement or waiver, including a waiver pursuant to Section 6.04,
may not:

                  (1) reduce the amount of Notes whose Holders must consent to
         an amendment, supplement or waiver, or consent to take any action under
         this Indenture or the Notes;

<PAGE>
                                      -70-

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

                  (3) reduce the principal of or premium on or change the stated
         maturity of any Note or change the date on which any Notes may be
         subject to redemption or repurchase or reduce the redemption or
         repurchase price therefor;

                  (4) make any Note payable in money other than that stated in
         the Note or change the place of payment from New York, New York;

                  (5) waive a Default in the payment of the principal of,
         interest on, or redemption payment with respect to, any Note;

                  (6)  make any changes in Sections 6.04 or 6.07 or this
         sentence of Section 8.02;

                  (7) modify or change any provision of this Indenture or the
         related definitions affecting the subordination or ranking of the Notes
         or any Guarantee in a manner that adversely affects the Holders;

                  (8) amend, change or modify in any material respect the
         obligation of the Company to make and consummate a Change of Control
         Offer in the event of a Change of Control, make and consummate an
         Excess Proceeds Offer with respect to any Asset Sale that has been
         consummated or modify any of the provisions or definitions with respect
         thereto; or

                  (9) release any Guarantor from any of its obligations under
         its Guarantee or this Indenture otherwise than in accordance with the
         terms of this Indenture.

                  In addition, without the consent of the Holders of 90% in
principal amount of the Notes then outstanding, no amendment may release any
Guarantor from any of its obligations under its Guarantee or this Indenture
otherwise than in accordance with the terms of this Indenture.

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

                  Upon the request of the Company, accompanied by a Board
Resolution authorizing the execution of any such supplemental indenture, and
upon the receipt by the Trustee of evidence satisfactory to the Trustee of the
consent of the Holders as aforesaid and upon receipt by the Trustee of the
documents described in Section 8.06, the Trustee shall join with the Company and
the Guarantors in the execution of such supplemental indenture unless such
supplemental indenture affects the Trustee's own rights, duties or immunities
under this Indenture, in which case the Trustee may in its discretion, but shall
not be obligated to, enter into such supplemental indenture.

                  It shall not be necessary for the consent of the Holders under
this Section 8.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                                      -71-

Section 8.03.     COMPLIANCE WITH TIA.

                  Every amendment to or supplement of this Indenture, the Notes
or the Guarantees shall comply with the TIA as then in effect.

Section 8.04.     REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, waiver or supplement 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 consenting Holder's Note, even if notation of the consent is not made on any
Note. Subject to the following paragraph, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note or portion of such Note by
written notice to the Trustee or the Company received before the date on which
the Trustee receives an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not theretofore revoked
such consent) to the amendment, supplement or waiver.

                  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 sentence 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 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 Noteholder, unless it makes a change described in any of
clauses (1) through (8) of Section 8.02, in which case, the amendment,
supplement or waiver shall bind only each Holder of a Note who has consented to
it and every subsequent Holder of a Note or portion of a Note that evidences the
same debt as the consenting Holder's Note; PROVIDED that any such waiver shall
not impair or affect the right of any Holder to receive payment of principal of
and interest on a Note, on or after the respective due dates expressed in such
Note, or to bring suit for the enforcement of any such payment on or after such
respective dates without the consent of such Holder.

Section 8.05.     NOTATION ON OR EXCHANGE OF NOTES.

                  If an amendment, supplement, or waiver changes the terms of a
Note, the Trustee may request the Holder to deliver it to the Trustee. In such
case, the Trustee shall place an appropriate notation on the Note about the
changed terms and return it to the Holder. Alternatively, if the Company or the
Trustee so determine, in exchange for the Note the Company 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 8.06.     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 8 is
authorized or permitted by this Indenture that all requisite consents have been
obtained or that no consents are required and that such amendment, supplement or
waiver constitutes the legal, valid and binding obligation of the Company and
any Guarantors, enforceable in accordance with its terms (subject to customary
exceptions). The Trustee may, but shall not be obligated to, execute any such
amendment, supplement or waiver which materially adversely affects the Trustee's
own rights, duties or immunities under this Indenture or otherwise.

expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when either:

         cancellation have become due and payable; (ii) the Company has
         irrevocably deposited or caused to be deposited with the Trustee in

         Indebtedness on such Notes not theretofore delivered to the Trustee for
         cancellation, for the principal of, premium, if any, and interest to
         the date of such deposit; (iii) no Default or Event of Default with
         respect to this Indenture or the Notes shall have occurred and be
         continuing on the date of such deposit or shall occur as a result of
         such deposit and such deposit will not result in a breach or violation
         of, or constitute a default under, any other instrument to which the
         Company is a party or by which it is bound; (iv) the Company has paid
         or caused to be paid all other sums payable hereunder by the Company;

         provided for relating to the satisfaction and discharge of this
         Indenture have been complied with and that such satisfaction and
         discharge does not result in a default under the Senior Credit Facility
         (if then in effect) or any other agreement or instrument then known to
         such counsel which binds or affects the Company; and (vi) that from and
         after the time of deposit, the money deposited shall not be subject to
         the rights of holders of Senior Indebtedness pursuant to the provisions
         of Article 10 or to the rights of holders of Guarantor Senior
         Indebtedness pursuant to the provisions of Article 11.

                  Notwithstanding the foregoing paragraph, the Company's
obligations in Article 2 and Sections 4.01, 4.07, 7.07, 9.05 and 9.06 shall
survive until the Notes are no longer outstanding pursuant to the last paragraph
of Section 2.08. After the Notes are no longer outstanding, the Company's
obligations in Sections 7.07 and 9.06 shall survive.

                  After such delivery or irrevocable deposit, the Trustee upon
request shall acknowledge in writing the discharge of the Company's and each
Guarantor's obligations under the Notes, the Guarantees and this Indenture
except for those surviving obligations specified above.

Company, by a Board Resolution, at any time, elect to have this Section be
applied to all outstanding Notes and any Guarantees upon compliance with the
conditions set forth in Section 9.04.

                  (b) Upon the Company's exercise under paragraph (a) hereof of
the option applicable to this paragraph (b), the Company and each Guarantor

be deemed to have been discharged from their respective obligations with respect
to all outstanding Notes and any Guarantees on the date the conditions set forth
below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal
Defeasance means that the Company and each Guarantor shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding Notes
and any Guarantees, which shall thereafter be deemed to be "outstanding" only
for the purposes of Section 9.05 and the other Sections of this Indenture
referred to in (i) and (ii) below, and to have satisfied all their other
respective obligations under such Notes and this Indenture (and the Trustee, on
written demand of and at the expense of the Company, shall execute proper
instruments acknowledging the same), and Holders and any amounts deposited under
Section 9.04 shall cease to be subject to any obligations to, or the rights of,
any holder of Senior Indebtedness under Article 10 or otherwise or any holder of
Guarantor Senior Indebtedness under Article 11 or otherwise, except for the
following provisions, which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of outstanding Notes to receive
solely from the trust fund described in Section 9.05, and as more fully set
forth in such Section, payments in respect of the principal of, premium, if any,
and interest on such Notes when such payments are due, (ii) the Company's
obligations with respect to such Notes under Article 2 and Section 4.07, (iii)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
the Company's obligations in connection therewith and (iv) this Article 9.
Subject to compliance with this Article 9, the Company may exercise its option
under this Section 9.02 notwithstanding the prior exercise of its option under
Section 9.03 below with respect to the Notes.

Section 9.03.     COVENANT DEFEASANCE.

                  (a) The Company may, at its option by a resolution of the
Board of Directors of the Company, at any time, elect to have this Section be
applied to all outstanding Notes upon compliance with the conditions set forth
in Section 9.04.

                  (b) Upon the Company's exercise under paragraph (a) hereof of
the option applicable to this paragraph (b), the Company and each Guarantor
shall, subject to the satisfaction of the conditions set forth in Section 9.04,
be released from their respective obligations under the covenants contained in
Sections 4.05, 4.08, 4.09 and 4.10 through 4.26, inclusive, and Article 5 with
respect to the outstanding Notes and any Guarantees on and after the date the
conditions set forth below are satisfied (hereinafter, "COVENANT DEFEASANCE"),
and the Notes and any Guarantees shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants,
but shall continue to be deemed "outstanding" for all other purposes hereunder
and Holders and any amounts deposited under Section 9.04 shall cease to be
subject to any obligations to, or the rights of, any holder of Senior
Indebtedness under Article 10 or otherwise or any holder of Guarantor Senior
Indebtedness under Article 11 or otherwise. For this purpose, such Covenant
Defeasance means that, with respect to the outstanding Notes and the Guarantees,
the Company and each Guarantor may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event or Default under Section
6.01(c), but, except as specified above, the remainder of this Indenture, such
Notes and

<PAGE>
                                      -74-

any Guarantees shall be unaffected thereby. In addition, upon the Company's
exercise under paragraph (a) above of the option applicable to this paragraph
(b), subject to the satisfaction of the conditions set forth in Section 9.04,
Sections 6.01(c), 6.01(d) and 6.01(e) shall not constitute Events of Default.

                  The following shall be the conditions to the application of
either Section 9.02 or 9.03 to the outstanding Notes and any Guarantees:

Defeasance:

         irrevocably deposited with the Trustee, in trust, for the benefit of
         the Holders, U.S. legal tender or U.S. Government Obligations, or a
         combination thereof, in such amounts as will be sufficient, in the
         opinion of a nationally recognized firm of independent public
         accountants, to pay the principal of, premium, if any, and interest on
         the Notes on the scheduled due dates therefore or on the applicable
         Redemption Date, as the case may be, PROVIDED that the Trustee shall
         have received an irrevocable written order from the Company instructing
         the Trustee to apply such U.S. legal tender or the proceeds of such
         U.S. government obligations to said payments with respect to the Notes;

                  (b) in the case of an election under Section 9.02, the Company
         shall have delivered to the Trustee an Opinion of Counsel reasonably
         acceptable to the Trustee confirming that (i) the Company has received
         from, or there has been published by, the Internal Revenue Service a
         ruling or (ii) since the date of this Indenture, there has been a
         change in the applicable federal income tax law, in either case to the
         effect that, and based thereon such Opinion of Counsel shall confirm
         that, the Holders will not recognize income, gain or loss for federal
         income tax purposes as a result of such Legal Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Legal
         Defeasance had not occurred;

                  (c) in the case of an election under Section 9.03, the Company
         shall have delivered to the Trustee an Opinion of Counsel confirming
         that the Holders will not recognize income, gain or loss for federal
         income tax purposes as a result of such Covenant Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Covenant
         Defeasance had not occurred;

                  (d) no Default or Event of Default shall have occurred and be
         continuing on the date of such deposit or insofar as Sections 6.01(f)
         and 6.01(g) are concerned, at any time in the period ending on the 91st
         day after the date of such deposit;

                  (e) such Legal Defeasance or Covenant Defeasance shall not
         result in a breach or violation of, or constitute a default under, this
         Indenture or any other material 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;

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

<PAGE>
                                      -75-

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

                  (h) the Company shall have delivered to the Trustee an Opinion
         of Counsel to the effect that (i) the trust funds will not be subject
         to any rights of any holders of Senior Indebtedness or Guarantor Senior
         Indebtedness, including, without limitation, those arising hereunder,
         and (ii) assuming no intervening event of the type described in
         Sections 6.01(f) and 6.01(g) and that no Holder is an insider of the
         Company, after the 91st day following the deposit or, if longer, ending
         on the day following the expiration of the longest preference period
         under any Bankruptcy Law (it being understood that this condition
         should not be deemed to be satisfied until the expiration of such
         period) the trust funds will not be subject to the effect of any
         applicable Bankruptcy Law;

                  (i) such Legal Defeasance or Covenant Defeasance shall not
         cause the Trustee to have a conflicting interest for purposes of the
         TIA with respect to any securities of the Company; and

                  (j) the Company shall have delivered to the Trustee an Opinion
         of Counsel stating that, as a result of such Legal Defeasance or
         Covenant Defeasance, neither the trust nor the Trustee will be required
         to register as an investment company under the Investment Company Act
         of 1940, as amended.

Section 9.05.     APPLICATION OF TRUST MONEY.

                  All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to Section 9.01 or 9.04 in
respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent as the Trustee may
determine, to the Holders of such Notes, of all sums due and to become due
thereon in respect of principal, premium, if any, and accrued interest, but such
money need not be segregated from other funds except to the extent required by
law.

                  The Company shall pay and indemnify the Trustee and its
officers, directors, agents and employees against any tax, fee or other charge
imposed on or assessed against any U.S. Government Obligations deposited
pursuant to Section 9.01 or 9.04 or the principal, premium, if any, and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the outstanding Notes.

                  Anything in this Article 9 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon a written
request of the Company in the form of an Officers' Certificate any money or U.S.
Government Obligations held by it as provided in Section 9.01 or 9.04 which, in
the opinion of a nationally-recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance, and thereupon
shall be relieved from all liability with respect to such money.

Section 9.06.     REPAYMENT TO THE COMPANY.

                  Subject to Sections 9.01, 9.02, 9.03, 9.04, 9.05 and 9.07, the
Trustee and the Paying Agent shall promptly pay to the Company upon written
request any excess U.S. legal tender or U.S. Government Obligations 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
written request any money held by them for the

<PAGE>
                                      -76-

payment of principal, premium, if any, or interest that remains unclaimed for
two years; PROVIDED that the Trustee or such Paying Agent, before being required
to make any payment, may at the expense of the Company cause to be published
once in a newspaper of general circulation in the City of New York or mail to
each Holder entitled to such money 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 9.07.     REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any U.S.
legal tender or U.S. Government Obligations in accordance with Section 9.01,
9.02 or 9.03 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company's and each Guarantor's
obligations under this Indenture, the Notes and the Guarantees shall be revived
and reinstated as though no deposit had occurred pursuant to this Article 9
until such time as the Trustee or Paying Agent is permitted to apply all such
U.S. legal tender or U.S. Government Obligations in accordance with Section
9.01; PROVIDED, HOWEVER, that if the Company or the Guarantors have made any
payment of principal of, premium, if any, or accrued interest on any Notes
because of the reinstatement of their obligations, the Company and each such
Guarantor shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the U.S. legal tender or U.S. Government Obligations
held by the Trustee or Paying Agent.

                                   ARTICLE 10

         entitled to receive payment and satisfaction in full in cash of all
         amounts due on or in respect of all Senior Indebtedness of the Company

         entitled but for the provisions of this Article 10 shall be paid by the
         liquidating trustee or agent or other Person making such payment or
         distribution, whether a trustee in bankruptcy, a receiver or
         liquidating trustee or otherwise, directly to the holders of Senior
         Indebtedness or their representative or representatives or to the
         trustee or trustees under any indenture under which any instruments
         evidencing any of such Senior Indebtedness may have been issued,
         ratably according to the aggregate amounts remaining unpaid on account
         of the Senior Indebtedness held or represented by each, to the extent
         necessary to make payment in full in cash of all Senior Indebtedness

         distribution to the holders of such Senior Indebtedness; and

                  (3) in the event that, notwithstanding the foregoing
         provisions of this Section 10.02, the Trustee or any Holder shall have
         received any payment or distribution of assets of the Company of any
         kind or character, whether in cash, property or securities, including,
         without limitation, by way of set-off or otherwise, in respect of the
         principal of, premium, if any, and interest on the Notes before all
         Senior Indebtedness is indefeasibly paid in full, then and in such
         event such payment or distribution shall be paid over or delivered
         forthwith to the trustee in bankruptcy, receiver, liquidating trustee,
         custodian, assignee, agent or other Person making payment or
         distribution of assets of the Company for application to the payment of

Company with or into, another Person or the liquidation or dissolution of the
Company following the conveyance, transfer or lease of its properties and assets

forth in Article 5 shall not be deemed a dissolution, winding-up, liquidation,
reorganization, assignment for the benefit of creditors or marshaling of assets
and liabilities of the Company for the purposes of this Article 10 if the Person
formed by such consolidation or the surviving entity of such merger or the
Person which acquires by conveyance, transfer or lease such properties and
assets substantially as an entirety, as the case may be, shall, as a part of

Section 10.03.    SUSPENSION OF PAYMENT WHEN SENIOR INDEBTEDNESS IN DEFAULT.

                  (a) Unless Section 10.02 shall be applicable, upon the
occurrence of a Payment Default on Designated Senior Indebtedness, no payment or
distribution (other than a payment or distribution of amounts previously
deposited in trust in accordance with the defeasance provisions described under
Article 9) of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other indebtedness of the Company being
subordinated to the payment of the Notes by the Company) may be made by or on
behalf of the Company or any Restricted Subsidiary, including, without
limitation, by way of set-off or otherwise, for or on account of the Notes, or
for or on account of the purchase, redemption or other acquisition of any Notes,
and neither the Trustee nor any holder or owner of any Notes shall take or
receive from the Company or any Restricted Subsidiary, directly or indirectly in
any manner, payment in respect of all or any portion of Notes commencing on the
date of receipt by the Trustee of written notice from the representative of the
holders of Designated Senior Indebtedness (the "Representative") of the
occurrence of such Payment Default, and in any such event, such prohibition
shall continue until such Payment Default is cured, waived in writing or
otherwise ceases to exist. At such time as the prohibition set forth in the
preceding sentence shall no longer be in effect, subject to the provisions of
the following paragraph, the Company shall resume making any and all required
payments in respect of the Notes, including any missed payments.

                  (b) Unless Section 10.02 shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness,
no payment or distribution (other than a payment or distribution of amounts
previously deposited in trust in accordance with the defeasance provisions
described under Article 9) of any kind or character (including, without
limitation, cash, property and any payment or distribution that may be payable
or deliverable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Notes by the Company) may be made by
the Company or any Restricted Subsidiary, including, without limitation, by way
of set-off or otherwise, for or on account of the Notes, or for or on account of
the purchase, redemption or other acquisition of any Notes, and neither the
Trustee nor any holder or owner of any Notes shall take or receive from the
Company or any Restricted Subsidiary, directly or indirectly in any manner,
payment in respect of all or any portion of the Notes for a period (a "PAYMENT
BLOCKAGE PERIOD") commencing on the date of receipt by the Trustee of written
notice from the Representative of such Non-Payment Event of Default unless and
until (subject to any blockage of payments that may then be in effect under the
preceding paragraph) the earliest of

                  (1) more than 179 days shall have elapsed since receipt of
          such written notice by the Trustee,

                  (2) such Non-Payment Event of Default shall have been cured or
          waived in writing or otherwise shall have ceased to exist or such
          Designated Senior Indebtedness shall have been paid in full, or

                  (3) such Payment Blockage Period shall have been terminated by
          written notice to the Company or the Trustee from such Representative,

after which, in the case of clause (1), (2) or (3), the Company shall resume
making any and all required payments in respect of the Notes, including any
missed payments. Notwithstanding any other provision of this Indenture, in no
event shall a Payment Blockage Period commenced in accordance with the
provisions of this Indenture described in this paragraph extend beyond 179 days
from the date of the receipt by the Trustee of the notice referred to above (the
"INITIAL BLOCKAGE PERIOD"). Any number of additional Payment Blockage Periods
may be commenced during the Initial Blockage Period; PROVIDED, HOWEVER, that no
such additional Payment Blockage Period shall extend beyond the Initial Blockage
Period. After the expiration of the Initial Blockage Period, no

<PAGE>
                                      -79-

Payment Blockage Period may be commenced until at least 180 consecutive days
have elapsed from the last day of the Initial Blockage Period. Notwithstanding
any other provision of this Indenture, no Non-Payment Event of Default with
respect to Designated Senior Indebtedness that existed or was continuing on the
date of the commencement of any Payment Blockage Period initiated by the
Representative shall be, or be made, the basis for the commencement of a second
Payment Blockage Period initiated by the Representative, whether or not within
the Initial Blockage Period, unless such Non-Payment Event of Default shall have
been cured or waived for a period of not less than 90 consecutive days.

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or any holder of Notes receives any payment or distribution of assets of
the Company of any kind, whether in cash, property or securities, including,
without limitation, by way of set-off or otherwise, in respect of the Notes
before all Senior Indebtedness of the Company is paid and satisfied in full in
cash, then such payment or distribution (other than a payment or distribution of
amounts previously deposited in trust in accordance with the defeasance
provisions described under Article 9) will be held by the recipient in trust for
the benefit of holders of Senior Indebtedness and will be immediately paid over
or delivered to the holders of Senior Indebtedness or their representative or
representatives to the extent necessary to make payment in full of all Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution, or provision therefor, to or for the holders of Senior
Indebtedness.

Section 10.04.    TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.

                  The Trustee and any agent of the Company or the Trustee shall
be entitled to all the rights set forth in this Article 10 with respect to any
Senior Indebtedness which 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 such agent of any of
its rights as such holder.

                  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 10, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee. The Trustee shall not be
deemed to owe any fiduciary duty to the holders of Senior Indebtedness and the
Trustee shall not be liable to any holder of Senior Indebtedness if it shall
mistakenly pay over or deliver to Holders, the Company or any other person
moneys or assets to which any holder of Senior Indebtedness shall be entitled by
virtue of this Article 10 or otherwise. Nothing in this Section 10.04 shall
affect the obligation of any other such Person receiving such payment or
distribution from the Trustee or any other Agent to hold such payment for the
benefit of, and to pay such payment over to, the holders of Senior Indebtedness.

Section 10.05.    SUBROGATION.

                  Upon the payment in full of all Senior Indebtedness, the
Holders shall be subrogated to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of,
premium, if any and interest on the Notes shall be paid in full. For purposes of
such subrogation, no payments or distributions to the holders of Senior
Indebtedness of any cash, property or securities to which the Holders or the
Trustee would be entitled except for the provisions of this Article 10, and no
payments pursuant to the provisions of this Article 10 to the holders of Senior
Indebtedness by Holders or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness and the Holders, be deemed
to be a payment or distribution by the Company to or on account of the Senior
Indebtedness.

<PAGE>
                                      -80-

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 10 shall
have been applied, pursuant to the provisions of this Article 10, to the payment
of all amounts payable under the Senior Indebtedness of the Company, then and in
such case the Holders shall be entitled to receive from the holders of such
Senior Indebtedness at the time outstanding any payments or distributions
received by such holders of such Senior Indebtedness in excess of the amount
sufficient to pay all amounts payable under or in respect of such Senior
Indebtedness in full in cash.

Section 10.06.    PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

                  The provisions of this Article 10 are and are intended solely
for the purpose of defining the relative rights of the Holders on the one hand
and the holders of Senior Indebtedness on the other hand. Nothing contained in
this Article 10 or elsewhere in this Indenture or in the Notes is intended to or
shall (a) impair, as among the Company, its creditors other than holders of
Senior Indebtedness 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 (b) affect the relative rights against the
Company of the Holders and creditors of the Company other than the holders of
Senior Indebtedness; or (c) prevent the Trustee or any Holder from exercising
all remedies otherwise permitted by applicable law upon a Default or an Event of
Default under this Indenture, subject to the rights, if any, under this Article
10 of the holders of Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of the Company referred
to in Section 10.02, to receive, pursuant to and in accordance with such
section, cash, property and securities otherwise payable or deliverable to the
Trustee or such Holder, or (2) under the conditions specified in Section 10.03,
to prevent any payment prohibited by such section or enforce their rights
pursuant to Section 10.03(c).

                  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 10 shall not be construed as preventing the occurrence of a Default or
an Event of Default hereunder.

Section 10.07.    TRUSTEE TO EFFECTUATE SUBORDINATION.

                  Each Holder of a Note by his acceptance thereof authorizes and
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article 10 and
appoints the Trustee his attorney-in-fact for any and all such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Company whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the timely filing of a claim for the unpaid balance
of the indebtedness of the Company owing to such Holder in the form required in
such proceedings.

Section 10.08.    NO WAIVER OF SUBORDINATION PROVISIONS.

                  (a) No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                  (b) Without limiting the generality of paragraph (a) of this
Section, 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

<PAGE>
                                      -81-

in this Article 10 or the obligations hereunder of the Holders to the holders of
Senior Indebtedness, do any one or more of the following: (1) 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; (2) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (3) release any Person liable in any manner for the collection or
payment of Senior Indebtedness; and (4) exercise or refrain from exercising any
rights against the Company and any other Person; PROVIDED, HOWEVER, that in no
event shall any such actions limit the right of the Holders to take any action
to accelerate the maturity of the Notes pursuant to Article 6 or to pursue any
rights or remedies hereunder or under applicable laws if the taking of such
action does not otherwise violate the terms of this Indenture.

Section 10.09.    NOTICE TO TRUSTEE.

                  (a) The Company shall give prompt written notice to the
Trustee of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee at its Corporate Trust Office in respect of the
Notes. Notwithstanding the provisions of this Article 10 or any other provision
of this Indenture, the Trustee shall not be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee in respect of the Notes, unless and until the Trustee shall have
received written notice thereof from the Company or a holder of Senior
Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
this Section 10.09, shall be entitled in all respects to assume that no such
facts exist; PROVIDED, HOWEVER, that if the Trustee shall not have received the
notice provided for in this Section 10.09 at least two Business Days prior to
the date upon which by the terms hereof any money may become payable for any
purpose under this Indenture (including, without limitation, the payment of the
principal of, premium, if any, or interest on any Note), then, anything herein
contained to the contrary notwithstanding but without limiting the rights and
remedies of the holders of Senior Indebtedness or any trustee, fiduciary or
agent therefor, the Trustee shall have full power and authority to receive such
money and to apply the same to the purpose for which such money was received and
shall not be affected by any notice to the contrary which may be received by it
within two Business Days prior to such date; nor shall the Trustee be charged
with knowledge of the curing of any such default or the elimination of the act
or condition preventing any such payment unless and until the Trustee shall have
received an Officers' Certificate to such effect.

                  (b) In the event that the Trustee determines in good faith
that further 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 10, 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 10, and if such
evidence is not furnished, the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

Section 10.10.    RELIANCE ON JUDICIAL ORDER OR CERTIFICATE OF LIQUIDATING
                  AGENT.

                  Upon any payment or distribution of assets of the Company
referred to in this Article 10, the Trustee, subject to the provisions of
Section 7.01, and the Holders shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding-up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit
of creditors, agent or other 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 payment or distribution, the holders of
Senior Indebtedness and

<PAGE>
                                      -82-

other Indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article 10.

Section 10.11.    NO SUSPENSION OF REMEDIES.

                  Nothing contained in this Article 10 shall limit the right of
the Trustee or the Holders to take any action to accelerate the maturity of the
Notes pursuant to Article 6 or to pursue any rights or remedies hereunder or
under applicable law, subject to the rights, if any, under this Article 10 of
the holders, from time to time, of Senior Indebtedness.

                                   ARTICLE 11

                               GUARANTEE OF NOTES

Section 11.01.    GUARANTEE.

                  Subject to the provisions of this Article 11, each Guarantor,
by execution of a Guarantee will, jointly and severally unconditionally
guarantee on a senior subordinated basis to each Holder and to the Trustee, on
behalf of the Holders, (i) the due and punctual payment of the principal of, and
premium, if any, 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 (including Additional Interest, if any) on the
overdue principal of, and premium, if any, and interest on the Notes, to the
extent lawful, and the due and punctual payment of all other Obligations of the
Company to the Holders or the Trustee (including without limitation amounts due
to the Trustee under Section 7.07) 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
Guarantor, by execution of a Guarantee, will, agree that its obligations
hereunder shall be absolute and unconditional, irrespective of, and shall be
unaffected by, any invalidity, irregularity or unenforceability of any such Note
or this Indenture, any failure to enforce the provisions of any such Note or
this Indenture, any waiver, modification or indulgence granted to the Company
with respect thereto by the Holder of such Note or the Trustee, or any other
circumstances which may otherwise constitute a legal or equitable discharge of a
surety or such Guarantor.

                  Each Guarantor, by execution of a Guarantee, will waive
diligence, presentment, demand for payment, filing of claims with a court in the
event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest or notice with respect to any such
Note or the Indebtedness evidenced thereby and all demands whatsoever, and will
covenant that the Guarantee will not be discharged as to any such Note except by
payment in full of the principal thereof, premium, if any, and interest thereon
as provided in Section 9.01. Each Guarantor, by execution of a Guarantee, will
further agree that, as between such Guarantor, on the one hand, and the Holders
and the Trustee, on the other hand, (i) the maturity of the Obligations
guaranteed hereby may be accelerated as provided in Article 6 for the purposes
of this Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration in respect of the Obligations guaranteed hereby,
and (ii) in the event of any declaration of acceleration of such Obligations as
provided in Article 6, such Obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of this
Guarantee. In addition, without limiting the foregoing provisions, upon the
effectiveness of an acceleration under Article 6, the Trustee shall promptly
make a demand for payment on the Notes

<PAGE>
                                      -83-

under the Guarantee provided for in this Article 11 and not discharged. Failure
to make such a demand shall not affect the validity or enforceability of the
Guarantee upon any Guarantor.

                  A Guarantee 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.

                  A Guarantee shall remain in full force and effect and continue
to be effective should any petition be filed by or against the Company for
liquidation or reorganization, should the Company become insolvent or make an
assignment for the benefit of creditors or should a receiver or trustee be
appointed for all or any significant part of the Company's assets, and shall, to
the fullest extent permitted by law, continue to be effective or be reinstated,
as the case may be, if at any time payment and performance of the Notes are,
pursuant to applicable law, rescinded or reduced in amount, or must otherwise be
restored or returned by any obligee on the Notes, whether as a "voidable
preference," "fraudulent transfer" or otherwise, all as though such payment or
performance had not been made. In the event that any payment, or any part
thereof, is rescinded, reduced, restored or returned, the Notes shall, to the
fullest extent permitted by law, be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.

                  No stockholder, member, officer, director, employee or
incorporator, past, present or future, of any Guarantor, as such, shall have any
personal liability under this Guarantee by reason of his, her or its status as
such stockholder, member, officer, director, employee or incorporator.

                  A Guarantor, by execution of a Guarantee, will have the right
to seek contribution from any non-paying Guarantor so long as the exercise of
such right does not impair the rights of the Holders under such Guarantee.

Section 11.02.    EXECUTION AND DELIVERY OF GUARANTEE.

                  A Guarantee shall be executed by either manual or facsimile
signature (promptly followed by the original signature page) of an Officer or an
Officer of a general partner, as the case may be, of such Guarantor.

                  If an officer of a Guarantor whose signature is on the
Guarantee no longer holds that office, such Guarantor's Guarantee shall be valid
nevertheless.

Section 11.03.    LIMITATION OF GUARANTEE.

                  Each Guarantor, and by its acceptance hereof each Holder and
the Trustee, hereby confirms that it is the intention of all such parties that
the Guarantee does not constitute a fraudulent transfer or conveyance for
purposes of Title 11 of the United States Code, as amended, the Uniform
Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
U.S. Federal or state law. To effectuate the foregoing intention, each Holder,
the Trustee and each Guarantor hereby irrevocably agree that the obligations of
a Guarantor under its Guarantee shall be limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such
Guarantor, and after giving effect to any collections from or payments made by
or on behalf of such Guarantor in respect of the obligations of such Guarantor
pursuant to this Article 11, result in the obligations of such Guarantor not
constituting such a fraudulent transfer or conveyance.

                                      -84-

Section 11.04.    ADDITIONAL GUARANTORS.

                  Any Person may become a Guarantor by executing and delivering
to the Trustee (a) a supplemental indenture in form and substance satisfactory
to the Trustee, which subjects such Person to the provisions of this Indenture
as a Guarantor, and (b) an Opinion of Counsel to the effect that such
supplemental indenture has been duly authorized and executed by such Person and
constitutes the legal, valid, binding and enforceable obligation of such Person
(subject to such customary exceptions concerning fraudulent conveyance laws,
creditors' rights and equitable principles as may be acceptable to the Trustee
in its discretion).

Section 11.05.    RELEASE OF GUARANTOR.

                  A Guarantor shall be released from all of its obligations
under its Guarantee if:

                  (i) the Guarantor has sold all or substantially all of its
         assets or the Company and the Restricted Subsidiaries have sold all of
         the Capital Stock of the Guarantor owned by them, in each case in a
         transaction in compliance with the terms of this Indenture (including
         Sections 4.13, 4.17, 4.24 and 5.01);

                  (ii) the Guarantor merges with or into or consolidates with,
         or transfers all or substantially all of its assets to, the Company or
         another Guarantor in a transaction in compliance with the terms of this
         Indenture (including Section 5.01); or

                  (iii) the Guarantor is designated an Unrestricted Subsidiary
         in compliance with the terms of this Indenture (including Section
         4.11);

and in each such case, such Guarantor has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such transactions have been complied
with and that such release is authorized and permitted hereunder.

                  The Trustee shall execute any documents reasonably requested
by the Company or a Guarantor in order to evidence the release of such Guarantor
from its obligations under its Guarantee endorsed on the Notes and under this
Article 11.

Section 11.06.    SUBORDINATION OF SUBROGATION AND OTHER RIGHTS; SUBROGATION.

                  Each Guarantor hereby agrees that any claim against the
Company that arises from the payment, performance or enforcement of such
Guarantor's obligations under the Guarantee or this Indenture, including,
without limitation, any right of subrogation, shall be subject and subordinate
to, and no payment with respect to any such claim of such Guarantor shall be
made before, the payment in full in cash of all outstanding Senior Indebtedness
and Guarantor Senior Indebtedness in accordance with the provisions provided
therefor in this Indenture.

Section 11.07.  GUARANTEE OBLIGATIONS SUBORDINATED TO GUARANTOR SENIOR
                INDEBTEDNESS.

                  Each Guarantor, by execution of a Guarantee, will covenant and
agree, and each Holder, by its acceptance thereof, will likewise covenant and
agree, that to the extent and in the manner hereinafter set forth in this
Article 11, the Indebtedness represented by the Guarantee and the payment of the
principal of, premium, if any, and interest on the Notes pursuant to the
Guarantee by such Guarantor are hereby expressly made subordi-

<PAGE>
                                      -85-

nate and subject in right of payment as provided in this Article 11 to the prior
indefeasible payment and satisfaction in full in cash of all existing and future
Guarantor Senior Indebtedness of such Guarantor.

                  This Section 11.07 and the following Sections 11.08 through
11.16 shall constitute a continuing offer to all Persons who, in reliance upon
such provisions, become holders of or continue to hold Guarantor Senior
Indebtedness of any Guarantor; and such provisions are made for the benefit of
the holders of Guarantor Senior Indebtedness of each Guarantor; and such holders
are made obligees hereunder and they or each of them may enforce such
provisions.

Section 11.08. PAYMENT OVER OF PROCEEDS UPON DISSOLUTION, ETC., OF A GUARANTOR.

                  In the event of:

               (1)  any insolvency or bankruptcy case or proceeding, or any
        receivership, liquidation, arrangement, reorganization or other similar
        case or proceeding in connection therewith, relative to a Guarantor or
        to its creditors, as such, or to its assets, whether voluntary or
        involuntary; or

               (2)  any liquidation, dissolution or other winding-up or other
        similar case or proceeding in connection therewith whether or not
        involving insolvency or bankruptcy, relative to a Guarantor or to its
        creditors, as such, or to such Guarantor's assets, whether voluntary or
        involuntary; or

               (3)  any general assignment for the benefit of creditors of a
        Guarantor; or

               (4)  any other marshaling of assets or liabilities of a Guarantor
        (except in connection with the merger or consolidation of a Guarantor or
        its liquidation or dissolution following the transfer of substantially
        all of its assets, upon the terms and conditions permitted under the
        circumstances described under Section 5.01).

(all of the foregoing events described in clauses (1) through (4) referred to
herein individually as a "GUARANTOR BANKRUPTCY PROCEEDING" and collectively as
"GUARANTOR BANKRUPTCY PROCEEDINGS"), the holders of Guarantor Senior
Indebtedness will be entitled to receive payment and satisfaction in full in
cash of all amounts due on or in respect of all Guarantor Senior Indebtedness
before the Holders are entitled to receive or retain any payment or distribution
of any kind on account of the Notes (except that Holders may receive payments of
amounts previously deposited in trust in accordance with the defeasance
provisions of this Indenture described under Article 9).

                Any payment or distribution of assets of a Guarantor of any
kind or character, whether in cash, property or securities, by set-off or
otherwise, to which the Holders or the Trustee would be entitled but for the
provisions of this Article 11 shall be paid by the liquidating trustee or agent
or other Person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
holders of Guarantor Senior Indebtedness or their representative or
representatives or to the trustee or trustees under any indenture under which
any instruments evidencing any of such Guarantor Senior Indebtedness may have
been issued, ratably according to the aggregate amounts remaining unpaid on
account of the Guarantor Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full in cash of all Guarantor Senior
Indebtedness remaining unpaid, after giving effect to any concurrent payment or
distribution to the holders of such Guarantor Senior Indebtedness.

                In the event that, notwithstanding the foregoing, the Trustee
or any Holder receives any payment or distribution of assets of a Guarantor of
any kind, whether in cash, property or securities, including, without
limitation, by way of set-off or otherwise, in respect of the Notes before all
Guarantor Senior Indebtedness of

<PAGE>
                                      -86-

a Guarantor is paid and satisfied in full in cash, then such payment or
distribution will be held by the recipient in trust for the benefit of holders
of Guarantor Senior Indebtedness and will be immediately paid over or delivered
to the holders of Guarantor Senior Indebtedness or their representative or
representatives to the extent necessary to make payment in full of all Guarantor
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution, or provision therefor, to or for the holders of
Guarantor Senior Indebtedness.

                  The consolidation of a Guarantor with, or the merger of a
Guarantor with or into, another Person or the liquidation or dissolution of a
Guarantor following the conveyance, transfer or lease of its properties and
assets substantially as an entirety to another Person upon the terms and
conditions set forth in Article 5 shall not be deemed a dissolution, winding-up,
liquidation, reorganization, assignment for the benefit of creditors or
marshaling of assets and liabilities of a Guarantor for the purposes of this
Article 11 if the Person formed by such consolidation or the surviving entity of
such merger or the Person which acquires by conveyance, transfer or lease such
properties and assets substantially as an entirety, as the case may be, shall,
as a part of such consolidation, merger, conveyance, transfer or lease, comply
with the conditions set forth in Article 5.

Section 11.09.  SUSPENSION OF GUARANTEE OBLIGATIONS WHEN GUARANTOR SENIOR
                INDEBTEDNESS IN DEFAULT.
                ---------------------------------------------------------------
                (a)  Unless Section 11.08 shall be applicable, upon the
occurrence of a Payment Default on Designated Senior Indebtedness, no payment or
distribution (other than a payment or distribution of amounts previously
deposited in trust in accordance with the defeasance provisions described under
Article 9) of any kind or character (including, without limitation, cash,
property and any payment or distribution which may be payable or deliverable by
reason of the payment of any other Indebtedness of such Guarantor being
subordinated to the payment of its Obligations on its Guarantee) may be made by
or on behalf of such Guarantor or any Restricted Subsidiary of such Guarantor,
including, without limitation, by way of set-off or otherwise, for or on account
of its Obligations on its Guarantee or for or on account of the purchase or
redemption or other acquisition of its Obligations under its Guarantee, and
neither the Trustee nor any holder or owner of any Notes shall take or receive
from any Guarantor or any Restricted Subsidiary of such Guarantor, directly or
indirectly in any manner, payment in respect of all or any portion of its
Obligations on its Guarantee commencing on the date of receipt by the Trustee of
written notice from the representative of the holders of Designated Senior
Indebtedness which constitutes Guarantor Senior Indebtedness (the "GUARANTOR
REPRESENTATIVE") of the occurrence of such Payment Default, and in any such
event, such prohibition shall continue until such Payment Default is cured,
waived in writing or otherwise ceases to exist. At such time as the prohibition
set forth in the preceding sentence shall no longer be in effect, subject to the
provisions of the following paragraph, such Guarantor shall resume making any
and all required payments in respect of its Obligations under its Guarantee,
including any missed payments.

                (b)  Unless Section 11.08 shall be applicable, upon the
occurrence of a Non-Payment Event of Default on Designated Senior Indebtedness
which constitutes Guarantor Senior Indebtedness, no payment or distribution
(other than a payment or distribution of amounts previously deposited in trust
in accordance with the defeasance provisions described under Article 9) of any
kind or character (including, without limitation, cash, property and any payment
or distribution which may be payable or deliverable by reason of the payment of
any other Indebtedness of such Guarantor being subordinated to the payment of
its Obligations on its Guarantee) may be made by such Guarantor or any
Restricted Subsidiary of such Guarantor, including, without limitation, by way
of set-off or otherwise, for or on account of its Obligations under its
Guarantee, or for or on account of the purchase or redemption or other
acquisition of its Obligations under its Guarantee, and neither the Trustee nor
any holder or owner of any Notes shall take or receive from such Guarantor or
any Restricted Subsidiary of such Guarantor, directly or indirectly in any
manner, payment in respect of or for any portion of its Obligations under its
Guarantee for a period (a "GUARANTOR PAYMENT BLOCKAGE PERIOD") commencing on the
date of receipt by the Trustee of written notice from the Guarantor
Representative of such Non-Payment Event of Default unless and

<PAGE>
                                      -87-

until (subject to any blockage of payments that may then be in effect under the
preceding paragraph) the earliest of

                      (1) more than 179 days shall have elapsed since receipt of
                  such written notice by the Trustee,

                      (2) such Non-Payment Event of Default shall have been
                  cured or waived in writing or shall have ceased to exist or
                  such Designated Senior Indebtedness which constitutes
                  Guarantor Senior Indebtedness shall have been paid in full or

                      (3) such Guarantor Payment Blockage Period shall have been
                  terminated by written notice to such Guarantor or the Trustee
                  from such Guarantor Representative

after which, in the case of clause (1), (2) or (3), such Guarantor shall resume
making any and all required payments in respect of its Obligations under its
Guarantee, including any missed payments. Notwithstanding any other provision of
this Indenture, in no event shall a Guarantor Payment Blockage Period commenced
in accordance with the provisions of this Section 11.09(b) extend beyond 179
days from the date of the receipt by the Trustee of the notice referred to above
(the "INITIAL GUARANTOR BLOCKAGE PERIOD"). Any number of additional Guarantor
Payment Blockage Periods may be commenced during the Initial Guarantor Blockage
Period; PROVIDED, HOWEVER, that no such additional Guarantor Payment Blockage
Period shall extend beyond the Initial Guarantor Blockage Period. After the
expiration of the Initial Guarantor Blockage Period, no Guarantor Payment
Blockage Period may be commenced until at least 180 consecutive days have
elapsed from the last day of the Initial Guarantor Blockage Period.
Notwithstanding any other provision of this Indenture, no Non-Payment Event of
Default with respect to Designated Senior Indebtedness which constitutes
Guarantor Senior Indebtedness that existed or was continuing on the date of the
commencement of any Guarantor Payment Blockage Period initiated by the Guarantor
Representative shall be, or be made, the basis for the commencement of a second
Guarantor Payment Blockage Period initiated by the Guarantor Representative,
whether or not within the Initial Guarantor Blockage Period, unless such
Non-Payment Event of Default shall have been cured or waived for a period of not
less than 90 consecutive days.

                  (c) In the event that, notwithstanding the foregoing, the
Trustee or the holder of Notes receives any payment or distribution of assets of
a Guarantor of any kind, whether in cash, property or securities, including,
without limitation, by way of set-off or otherwise, in respect of such
Guarantor's Obligations under its Guarantee before all Senior Indebtedness which
constitutes Guarantor Senior Indebtedness is paid and satisfied in full in cash,
then such payment or distribution (other than a payment or distribution of
amounts previously deposited in trust in accordance with the defeasance
provisions described under Article 9) will be held by the recipient in trust for
the benefit of holders of such Senior Indebtedness and will be immediately paid
over or delivered to the holders of such Senior Indebtedness or their
representative or representatives to the extent necessary to make payment in
full of all such Senior Indebtedness remaining unpaid, after giving effect to
any concurrent payment or distribution, or provision therefor, to or for holders
of such Senior Indebtedness.

Section 11.10.    TRUSTEE'S RELATION TO GUARANTOR SENIOR INDEBTEDNESS.

                  The Trustee and any Paying Agent shall be entitled to all the
rights set forth in this Article 11 with respect to any Guarantor Senior
Indebtedness which may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Guarantor Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee or any
Paying Agent of any of its rights as such holder. Nothing in this Article 11
shall apply to claims of, or payments to, the Trustee for its compensation owing
pursuant to and in accordance with the first sentence of Section 7.07.

<PAGE>
                                      -88-

                  With respect to the holders of Guarantor 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 11, and no implied
covenants or obligations with respect to the holders of Guarantor Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of Guarantor Senior
Indebtedness and the Trustee shall not be liable to any holder of Guarantor
Senior Indebtedness (other than for its willful misconduct or gross negligence)
if it shall in good faith mistakenly pay over or deliver to the Holders, the
Company or any other Person moneys or assets to which any holder of Guarantor
Senior Indebtedness shall be entitled by virtue of this Article 11 or otherwise.
Nothing in this Section 11.10 shall affect the obligation of any other such
Person, the Company, or the Holders to hold such money or assets for the benefit
of, and to pay such money or assets over to, the holders of the Guarantor Senior
Indebtedness or their applicable representative or representatives.

Section 11.11.    SUBROGATION TO RIGHTS OF HOLDERS OF GUARANTOR SENIOR
                  INDEBTEDNESS.

                  Upon the payment in full of all amounts payable under or in
respect of all Guarantor Senior Indebtedness of a Guarantor, the Holders shall
be subrogated to the rights of the holders of such Guarantor Senior Indebtedness
to receive payments and distributions of cash, property and securities of such
Guarantor made on such Guarantor Senior Indebtedness until all amounts due to be
paid under the Guarantee shall be paid in full. For the purposes of such
subrogation, no payments or distributions to holders of Guarantor Senior
Indebtedness of any cash, property or securities to which Holders would be
entitled except for the provisions of this Article 11 and no payments over
pursuant to the provisions of this Article 11 to holders of Guarantor Senior
Indebtedness by Holders, shall, as among each Guarantor, its creditors other
than holders of Guarantor Senior Indebtedness and the Holders, be deemed to be a
payment or distribution by such Guarantor to or on account of such Guarantor
Senior Indebtedness.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article 11 shall
have been applied, pursuant to the provisions of this Article 11, to the payment
of all amounts payable under Guarantor Senior Indebtedness, then and in such
case, the Holders shall be entitled to receive from the holders of such
Guarantor Senior Indebtedness at the time outstanding any payments or
distributions received by such holders of Guarantor Senior Indebtedness in
excess of the amount sufficient to pay all amounts payable under or in respect
of such Guarantor Senior Indebtedness in full in cash.

Section 11.12.    GUARANTEE SUBORDINATION PROVISIONS SOLELY TO DEFINE RELATIVE
                  RIGHTS.

                  The subordination provisions of this Article 11 are and are
intended solely for the purpose of defining the relative rights of the Holders
on the one hand and the holders of Guarantor Senior Indebtedness on the other
hand. Nothing contained in this Article 11 or elsewhere in this Indenture or in
the Notes is intended to or shall (a) impair, as among each Guarantor, its
creditors other than holders of its Guarantor Senior Indebtedness and the
Holders, the obligation of such Guarantor, which is absolute and unconditional,
to make payments to the Holders in respect of its Obligations on its Guarantee
in accordance with its terms; or (b) affect the relative rights against such
Guarantor of the Holders and creditors of such Guarantor other than the holders
of the Guarantor Senior Indebtedness; or (c) prevent any Holder from exercising
all remedies otherwise permitted by applicable law upon a Default or an Event of
Default under this Indenture, subject to the rights, if any, under this Article
11 of the holders of Guarantor Senior Indebtedness (1) in any case, proceeding,
dissolution, liquidation or other winding-up, assignment for the benefit of
creditors or other marshaling of assets and liabilities of any Guarantor
referred to in Section 11.08, to receive, pursuant to and in accordance with
such Section, cash, property and securities otherwise payable or deliverable to
such Holder, or (2) under the conditions specified in Section 11.09, to prevent
any payment prohibited by such Section or enforce their rights pursuant to
Section 11.09(c).

<PAGE>
                                      -89-

                  The failure by any Guarantor to make a payment in respect of
its obligations on its Guarantee by reason of any provision of this Article 11
shall not be construed as preventing the occurrence of a Default or an Event of
Default hereunder.

Section 11.13.    TRUSTEE TO EFFECTUATE SUBORDINATION.

                  Each Holder by his acceptance of a Guarantee agrees to be
bound by such provisions and authorizes and directs the Trustee, on his behalf,
to take such action as may be necessary or appropriate to effectuate the
subordination provisions in this Article 11 and appoints the Trustee his
attorney-in-fact for any and all such purposes, including, in the event of any
Guarantor Bankruptcy Proceeding or other dissolution, winding-up, liquidation or
reorganization of a Guarantor whether in bankruptcy, insolvency, receivership
proceedings, or otherwise, the prompt and timely filing of a claim for the
unpaid balance of the indebtedness of such Guarantor owing to such Holder in the
form required in such proceedings and the causing of such claim to be approved.
If the Trustee does not file such a claim prior to 30 days before the expiration
of the time to file such a claim, the holders of Guarantor Senior Indebtedness,
or any Guarantor Representative, may, and hereby are authorized to, file such a
claim on behalf of Holders of the applicable Notes.

Section 11.14.    NOTICE TO TRUSTEE.

                  (a)   The Company or any Guarantor shall give prompt written
notice to a Responsible Officer of the Trustee of any fact known to the Company
or any such Guarantor which would prohibit the making of any payment to or by
the Trustee at its Corporate Trust Office in respect of the Guarantees pursuant
to the provisions of this Article 11. Notwithstanding the provisions of this
Article 11 or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Guarantees, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Guarantor Senior Indebtedness or from any trustee,
fiduciary, representative, or agent therefor no later than two Business Days
prior to such payment; and, prior to the receipt of any such written notice, the
Trustee, subject to the provisions of this Section 11.14, and subject to the
provisions of Sections 7.01 and 7.02, shall be entitled in all respects to
assume that no such facts exist; PROVIDED, HOWEVER, that if the Trustee shall
not have received the notice referred to in this Section 11.14 at least one
Business Day prior to the date upon which by the terms hereof any such payment
may become payable for any purpose under this Indenture (including, without
limitation, the payment of the principal of, premium, if any, or interest on any
Note), then, anything herein contained to the contrary notwithstanding but
without limiting the rights and remedies of the holders of Guarantor Senior
Indebtedness or any trustee, fiduciary, representative, or agent therefor as
against the Holders or any other Person, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it less than one Business Day prior to such date; nor
shall the Trustee be charged with knowledge of the curing of any such applicable
default in respect of Designated Senior Indebtedness or the elimination of the
act or condition preventing any such payment unless and until the Trustee shall
have received an Officers' Certificate to such effect (subject to the rights of
the holders of the Designated Senior Indebtedness under Section 11.09). Nothing
contained in this Section 11.14 shall limit the right of holders of Senior
Indebtedness to recover payments as contemplated by Section 11.08. The Trustee
shall be entitled to rely upon 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) Subject to the provisions of Section 7.01, the Trustee
shall be entitled to rely (to the extent reasonable and in good faith) on the
delivery to it of a written notice to the Trustee and the Company or a

<PAGE>
                                      -90-

Guarantor by a Person representing itself to be a holder of Guarantor Senior
Indebtedness (or a trustee, fiduciary, representative, or agent therefor) for
purposes of establishing that such notice actually has been given by a holder of
Guarantor Senior Indebtedness (or a trustee, fiduciary, representative, or agent
therefor); PROVIDED, HOWEVER, that failure to give such notice to the Company or
a Guarantor shall not affect in any way the ability of the Trustee to rely on
such notice. In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
Guarantor Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 11, the Trustee may request such Person to furnish
evidence not unsatisfactory to the Trustee as to the amount of Guarantor 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 11, and if such evidence is not
furnished, the Trustee, acting in good faith, may defer any payment to such
Person pending judicial determination as to the right of such Person to receive
such payment.

Section 11.15.    APPLICATION OF CERTAIN ARTICLE 11 PROVISIONS.

                  The provisions of Sections 10.08, 10.10 and 10.11 shall apply,
MUTATIS MUTANDIS, to each Guarantor and their respective holders of Guarantor
Senior Indebtedness and the rights, duties and obligations set forth therein
shall govern the rights, duties and obligations of each Guarantor, the holders
of Guarantor Senior Indebtedness and the Holders with respect to the Guarantee
and all references therein to Article 10 shall mean this Article 11.

                              (REVERSE OF SECURITY)

               12 3/4% SENIOR SUBORDINATED NOTE DUE 2007, SERIES A

               1. INTEREST. AAVID THERMAL TECHNOLOGIES, INC., a Delaware
corporation (the "COMPANY"), promises to pay interest on the principal amount of
this Note at the rate PER ANNUM shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the date of the original issuance of the Notes. The Company will
pay interest semi-annually in arrears on each Interest Payment Date, commencing
August 1, 2000. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest (without regard to any applicable grace
periods) to the extent lawful from time to time on demand at the rate borne by
the Notes.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on July 15 or January 15 immediately preceding the
Interest Payment Date (whether or not such day is a Business Day) even if the
Notes are cancelled on registration of transfer or registration of exchange
after such Record Date. Holders must surrender Notes to a Paying Agent to
collect principal payments. Payments of principal and premium, if any, will be
made (on presentation of such Notes if in certificated form) in money of the
United States that at the time of payment is legal tender for payment of public
and private debts; PROVIDED, HOWEVER, that the Company may pay principal,
premium, if any, and interest by check payable or wire transfer in such money.
The Company may deliver any such interest payment to the Paying Agent or to a
Holder at the Holder's registered address.

                  3. PAYING AGENT AND REGISTRAR. Initially, Bankers Trust
Company, a New York banking corporation organized under the laws of the state of
New York (the "TRUSTEE"), will act as Paying Agent and Registrar. The Company
may change any Paying Agent, Registrar or co-Registrar without notice to the
Holders. Neither the Company nor any of its Subsidiaries or Affiliates may act
as Paying Agent but may act as Registrar or co-Registrar.

                  4.  INDENTURE.  The Company issued this Note under an
Indenture, dated as of, 2000 (the "INDENTURE"), by and among the Company, the
Guarantors and the Trustee.  This Note is one of a duly authorized issue of
Initial Notes of the Company designated as its 12 3/4% Senior Subordinated Notes
due 2007, Series A (the "NOTES"). The Notes are limited in aggregate principal
amount to $150,000,000. The Notes include the Initial Notes and the Exchange
Notes (as defined below) issued in exchange for the Initial Notes pursuant to
the Indenture. The Initial Notes and the Exchange Notes are treated as a single
class of securities under the Indenture. Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-
77bbbb)(the "TIA"), as in effect on the date of the Indenture. Notwithstanding
anything to the contrary herein, the Notes are subject to all such terms, and
Holders of Notes are referred to the Indenture and the TIA for a statement of
them.

                  5. SUBORDINATION. Except to the extent set forth in paragraph
10, the Notes are general unsecured obligations of the Company and subordinated
in right of payment, in the manner and to the extent set forth in the Indenture,
to the prior payment in full in cash of all Senior Indebtedness of the Company,
whether outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed. Each Holder by his acceptance hereof agrees to
be bound by such provisions and authorizes and expressly directs the Trustee, on
his behalf, to take such action as may be necessary or appropriate to effectuate
the subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

                  6. GUARANTEE. The obligations of the Company hereunder are
guaranteed on a senior subordinated basis by the Guarantors. Each Guarantee by a
Guarantor is subordinated in right of payment to all Guarantor Senior
Indebtedness of such Guarantor to the same extent that the Notes are
subordinated to Senior Indebtedness of the Company.

                  7.       REDEMPTION.

                  (a) The Notes will be redeemable at the option of the Company,
in whole or in part, during the 24-month period beginning February 1, 2004 at a
price equal to 100% of the principal amount thereof, plus an applicable Make
Whole Premium, and thereafter at 102% of the principal amount, in each case,
with accrued and unpaid interest, if any, to the date of redemption; PROVIDED,
HOWEVER, that at maturity the Notes shall be redeemable at 100% of principal
amount outstanding.

                  For the purposes of the foregoing, the "Make Whole Premium"
means, with respect to a Note, an amount equal to the excess, if any, of (1) the
present value as of the date of such prepayment of the remaining semi-annual
interest payments, if any, and the principal payment including premium due on
such Note as if such Note were redeemed on February 1, 2006, computed using a
discount rate equal to the Treasury Rate plus 75 basis points, over (2) the
outstanding principal amount of such Note. In no case shall the Make Whole
Premium be negative.

                  (b) OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.
Notwithstanding the foregoing, the Company may redeem in the aggregate up to 35%
of the original principal amount of Notes at any time and from time to time
prior to February 2, 2003 at a Redemption Price equal to 112.75% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the Redemption Date out of the Net Proceeds of one or more Public Equity
Offerings; provided that

                  (1)  at least 65% of the principal amount of Notes originally
issued remains outstanding immediately after the occurrence of any such
redemption and

                  (2)  any such redemption occurs within 60 days following the
closing of any such Public Equity Offering.

                  8. NOTICE OF REDEMPTION. Notice of redemption under paragraphs
6(a) and 6(b) of this Note will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  9. OFFERS TO PURCHASE. The Indenture provides that, after
certain Asset Sales and upon the occurrence of a Change of Control (as defined
in the Indenture), and subject to further limitations contained therein, the
Company will make an offer to purchase certain amounts of the Notes in
accordance with the procedures set forth in the Indenture.

                  10. REGISTRATION RIGHTS. Pursuant to the Registration Rights
Agreement by and among the Company, the Guarantors and the Initial Purchasers,

material respects other than this paragraph 10 to the Initial Notes. The Holders
of the Initial Notes shall be entitled to receive certain Additional Interest
payments in the event such exchange offer is not consummated and upon certain
other conditions, all pursuant to and in accordance with the terms of the
Registration Rights Agreement.

                  11. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental charges payable in connection
therewith as permitted by the Indenture. The Registrar need not register the
transfer of or exchange of any Notes or portions thereof selected for
redemption.

                  12. PERSONS DEEMED OWNERS. The registered Holder of a Note
shall be treated as the owner of it for all purposes.

                  13. UNCLAIMED MONEY. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, Holders entitled to money must
look to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

                  14. DEFEASANCE AND COVENANT DEFEASANCE. If the Company at any
time deposits with the Trustee U.S. legal tender and/or U.S. Government
Obligations sufficient to pay the principal of and interest on the Notes to

relating to defeasance, the Company will be discharged from certain provisions
of the Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest on the Notes).

                  15. AMENDMENTS, SUPPLEMENTS, AND WAIVERS. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
written consent of the holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the holders of a majority in aggregate principal amount of the Notes
then outstanding. Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency, provide for uncertificated
Notes in addition to or in place of certificated Notes or make any other change
that does not adversely affect in any material respect the rights of any Holder
of a Note.

                  16. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, make payments in respect of

other payment restrictions affecting Subsidiaries, merge or consolidate with any

limitations are subject to a number of important qualifications and exceptions.
The Company must annually report to the Trustee on compliance with such
limitations.

                  17. SUCCESSOR ENTITY. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the
Notes and the Indenture, and immediately before and thereafter no Default exists
and certain other conditions are satisfied, the predecessor entity will be
released from those obligations.

                  18. DEFAULTS AND REMEDIES. Events of Default are set forth in
the Indenture. If an Event of Default (other than an Event of Default pursuant
to Section 6.01(f) or (g) of the Indenture) shall have occurred and be

<PAGE>
                                     -102-

Notes then outstanding, may declare to be immediately due and payable the entire
principal amount of all the Notes then outstanding plus accrued interest to the
date of acceleration; PROVIDED, HOWEVER, that after such acceleration but before
a judgment or decree based on such acceleration is obtained by the Trustee, the
holders of a majority in aggregate principal amount of the outstanding Notes may
rescind and annul such acceleration and its consequences if all existing Events
of Default, other than the nonpayment of principal, premium, if any, or interest
that has become due solely because of the acceleration, have been cured or
waived. No such rescission shall affect any subsequent Default or impair any
right consequent thereto. In case an Event of Default specified in Section
6.01(f) or (g) of the Indenture occurs, such principal amount, together with
premium, if any, and interest with respect to all of the Notes, shall be due and
payable immediately without any declaration or other act on the part of the
Trustee or the Holders.

deposits from, and perform services for the Company, and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

                  20. NO RECOURSE AGAINST OTHERS. As more fully described in the
Indenture, no director, officer, employee, stockholder or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Notes or the Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. Each Noteholder by accepting a Note
waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Notes.

                  21. AUTHENTICATION. This Note shall not be valid until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                  22. GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES TO THE INDENTURE HAS AGREED

                              (REVERSE OF SECURITY)

               12 3/4% SENIOR SUBORDINATED NOTE DUE 2007, SERIES B

                  1. INTEREST. AAVID THERMAL TECHNOLOGIES, INC., a Delaware
corporation (the "COMPANY"), promises to pay interest on the principal amount of
this Note at the rate PER ANNUM shown above. Interest on the Notes will accrue
from the most recent date on which interest has been paid or, if no interest has
been paid, from the date of the original issuance of the Notes. The Company will
pay interest semi-annually in arrears on each Interest Payment Date, commencing
August 1, 2000. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  The Company shall pay interest on overdue principal and on
overdue installments of interest (without regard to any applicable grace
periods) to the extent lawful from time to time on demand at the rate borne by
the Notes.

                  2. METHOD OF PAYMENT. The Company shall pay interest on the
Notes (except defaulted interest) to the Persons who are the registered Holders
at the close of business on July 15 or January 15 preceding the Interest Payment
Date (whether or not such day is a Business Day) even if the Notes are cancelled
on registration of transfer or registration of exchange after such Record Date.
Holders must surrender Notes to a Paying Agent to collect principal payments.
Payments of principal and premium, if any, will be made (on presentation of such
Notes if in certificated form) in money of the United States that at the time of
payment is legal tender for payment of public and private debts; PROVIDED,
HOWEVER, that the Company may pay principal, premium, if any, and interest by
check payable in such money. The Company may deliver any such interest payment
to the Paying Agent or to a Holder at the Holder's registered address.

                  3. PAYING AGENT AND REGISTRAR. Initially, Bankers Trust
Company, a banking organization organized under the laws of New York (the
"TRUSTEE"), will act as Paying Agent and Registrar. The Company may change any
Paying Agent, Registrar or co-Registrar without notice to the Holders. Neither
the Company nor any of its Subsidiaries or Affiliates may act as Paying Agent
but may act as Registrar or co-Registrar.

                  4. INDENTURE. The Company issued this Note under an Indenture,
dated as of February 2, 2000 (the "INDENTURE"), by and among the Company, the
Guarantors and the Trustee. This Note is one of a duly authorized issue of Notes
of the Company designated as its 12 3/4% Senior Subordinated Notes due 2007,
Series B (the "EXCHANGE NOTES"), issued in exchange for the initial 12 3/4%
Senior Subordinated Notes due 2007, Series A (the "INITIAL NOTES" and, together
with the Exchange Notes, the "NOTES"). The Notes are limited in aggregate
principal amount to $150,000,000. Capitalized terms herein are used as defined
in the Indenture unless otherwise defined herein. The terms of the Notes include
those stated in the Indenture and those made part of the Indenture by reference
to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA"), as in effect on the date of the Indenture. Notwithstanding anything to
the contrary herein, the Notes are subject to all such terms, and Holders of
Notes are referred to the Indenture and the TIA for a statement of them.

                  5. SUBORDINATION. Except to the extent set forth in paragraph
10, the Notes are general unsecured obligations of the Company and subordinated
in right of payment, in the manner and to the extent set forth in the Indenture,
to the prior payment in full in cash of all Senior Indebtedness of the Company,
whether outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed. Each Holder by his acceptance hereof agrees to
be bound by such provisions and authorizes and expressly directs the Trustee, on
his behalf, to take such action as may be necessary or appropriate to effectuate
the subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

<PAGE>
                                     -109-

                  6. GUARANTEE. The obligations of the Company hereunder are
guaranteed on a senior subordinated basis by the Guarantors. Each Guarantee by a
Guarantor is subordinated in right of payment to all Guarantor Senior
Indebtedness of such Guarantor to the same extent that the Notes are
subordinated to Senior Indebtedness of the Company.

                  7.       REDEMPTION.

                  (a) The Notes will be redeemable at the option of the Company,
in whole or in part, during the 24-month period beginning February 1, 2004 at a
price equal to 100% of the principal amount thereof, plus and applicable Make
Whole Premium, and thereafter at 102% of the principal amount, in each case,
with accrued and unpaid interest, if any, to the date of redemption; PROVIDED,
HOWEVER, that at maturity the Notes shall be redeemable at 100% of principal
amount outstanding.

                  For the purposes of the foregoing, the "Make Whole Premium"
means, with respect to a Note, an amount equal to the excess, if any, of (1) the
present value as of the date of such prepayment of the remaining semi-annual
interest payments, if any, and the principal payment including premium due on
such Note as if such Note were redeemed on February 1, 2006, computed using a
discount rate equal to the Treasury Rate plus 75 basis points, over (2) the
outstanding principal amount of such Note. In no case shall the Make Whole
Premium be negative.

                  (b) OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS.
Notwithstanding the foregoing, the Company may redeem in the aggregate up to 35%
of the original principal amount of Notes at any time and from time to time
prior to February 2, 2003 at a Redemption Price equal to 112.75% of the
aggregate principal amount so redeemed, plus accrued and unpaid interest, if
any, to the Redemption Date out of the Net Proceeds of one or more Public Equity
Offerings; provided that

                  (1) at least 65% of the principal amount of Notes originally
         issued remains outstanding immediately after the occurrence of any such
         redemption and

                  (2) any such redemption occurs within 60 days following the
         closing of any such Public Equity Offering.

                  8. NOTICE OF REDEMPTION. Notice of redemption under paragraphs
6(a) and 6(b) of this Note will be mailed at least 30 days but not more than 60
days before the Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.

                  Except as set forth in the Indenture, if monies for the
redemption of the Notes called for redemption shall have been deposited with the
Paying Agent for redemption on such Redemption Date, then, unless the Company
defaults in the payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued interest, if any.

                  9. OFFERS TO PURCHASE. The Indenture provides that, after
certain Asset Sales and upon the occurrence of a Change of Control (as defined
in the Indenture), and subject to further limitations contained therein, the
Company will make an offer to purchase certain amounts of the Notes in
accordance with the procedures set forth in the Indenture.

                  10. DENOMINATIONS; TRANSFER; EXCHANGE. The Notes are in
registered form, without coupons, in denominations of $1,000 and integral
multiples thereof. A Holder shall register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
certain transfer taxes or similar governmental

<PAGE>
                                     -110-

charges payable in connection therewith as permitted by the Indenture. The
Registrar need not register the transfer of or exchange of any Notes or portions
thereof selected for redemption.

                  11. PERSONS DEEMED OWNERS. The registered Holder of a Note
shall be treated as the owner of it for all purposes.

                  12. UNCLAIMED MONEY. If money for the payment of principal or
interest remains unclaimed for two years, the Trustee and the Paying Agent will
pay the money back to the Company. After that, Holders entitled to money must
look to the Company for payment as general creditors unless an "abandoned
property" law designates another person.

                  13. DEFEASANCE AND COVENANT DEFEASANCE. If the Company at any
time deposits with the Trustee U.S. legal tender and/or U.S. Government
Obligations sufficient to pay the principal of and interest on the Notes to
redemption or maturity and complies with the other provisions of the Indenture
relating to defeasance, the Company will be discharged from certain provisions
of the Indenture and the Notes (including certain covenants, but excluding its
obligation to pay the principal of and interest on the Notes).

                  14. AMENDMENTS, SUPPLEMENTS, AND WAIVERS. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
written consent of the holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or Event of
Default or noncompliance with any provision may be waived with the written
consent of the holders of a majority in aggregate principal amount of the Notes
then outstanding. Without notice to or consent of any Holder, the parties
thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, defect or inconsistency, provide for uncertificated
Notes in addition to or in place of certificated Notes or make any other change
that does not adversely affect in any material respect the rights of any Holder
of a Note.

                  15. RESTRICTIVE COVENANTS. The Indenture imposes certain
limitations on the ability of the Company and its Restricted Subsidiaries to,
among other things, incur additional Indebtedness, make payments in respect of
its Capital Stock, enter into transactions with Affiliates, create dividend or
other payment restrictions affecting Subsidiaries, merge or consolidate with any
other person, or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of the Company's or any Guarantor's assets. Such
limitations are subject to a number of important qualifications and exceptions.
The Company must annually report to the Trustee on compliance with such
limitations.

                  16. SUCCESSOR ENTITY. When a successor entity assumes, in
accordance with the Indenture, all the obligations of its predecessor under the
Notes and the Indenture, and immediately before and thereafter no Default exists
and certain other conditions are satisfied, the predecessor entity will be
released from those obligations.

                  17. DEFAULTS AND REMEDIES. Events of Default are set forth in
the Indenture. If an Event of Default (other than an Event of Default pursuant
to Section 6.01(f) or (g) of the Indenture) shall have occurred and be
continuing, then the Trustee or the holders of not less than 25% in aggregate
principal amount of the Notes then outstanding, may declare to be immediately
due and payable the entire principal amount of all the Notes then outstanding
plus accrued interest to the date of acceleration; PROVIDED, HOWEVER, that after
such acceleration but before a judgment or decree based on such acceleration is
obtained by the Trustee, the holders of a majority in aggregate principal amount
of the outstanding Notes may rescind and annul such acceleration and its
consequences if all existing Events of Default, other than the nonpayment of
principal, premium, if any, or interest that has become due solely because of
the acceleration, have been cured or waived. No such rescission shall affect any
subsequent Default or impair any right consequent thereto. In case an Event of
Default specified in Section 6.01(f) or (g) of the Indenture occurs, such
principal amount, together with premium, if any, and interest

<PAGE>
                                     -111-

with respect to all of the Notes, shall be due and payable immediately without
any declaration or other act on the part of the Trustee or the Holders.

                  18. TRUSTEE DEALINGS WITH COMPANY. The Trustee under the
Indenture, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company, and may otherwise deal with
the Company, its Subsidiaries or their respective Affiliates as if it were not
the Trustee.

                  19. NO RECOURSE AGAINST OTHERS. As more fully described in the
Indenture, no director, officer, employee, stockholder or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Notes or the Indenture or for any claim based on, in respect of or by reason
of such obligations or their creation. Each Noteholder by accepting a Note
waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Notes.

                  20. AUTHENTICATION. This Note shall not be valid until the
Trustee or Authenticating Agent manually signs the certificate of authentication
on this Note.

                  21. GOVERNING LAW. THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO
CONTRACTS MADE AND PERFORMED WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW. EACH OF THE PARTIES TO THE INDENTURE HAS AGREED
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 NOTE.

                  22. ABBREVIATIONS AND DEFINED TERMS. Customary abbreviations
may be used in the name of a Holder of a Note or an assignee, such as: TEN COM

tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

                  22. CUSIP NUMBERS. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes as a convenience to the Holders.
No representation is made as to the accuracy of such numbers as printed on the
Notes and reliance may be placed only on the other identification numbers
printed hereon.

                  23. INDENTURE. Each Holder, by accepting a Note, agrees to be
bound by all of the terms and provisions of the Indenture, as the same may be
amended from time to time.

Attention:  Corporate Trust and Agency Services

Ladies and Gentlemen:

                  This certificate is delivered to request a transfer of
$________ principal amount of the 12 3/4% Senior Subordinated Notes due 2007,
Series A, of Aavid Thermal Technologies, Inc. (the "COMPANY") and any guarantee

of the new beneficial owner as follows:

                  Name:---------------------------------------------
                  Address:------------------------------------------
                  Taxpayer ID Number:-------------------------------

                  The undersigned represents and warrants to you that:

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

                  2. We acknowledge that we have had access to such financial
and other information, and have been afforded the opportunity to ask such
questions of representatives of the Company and receive answers thereto, as we
deem necessary.

                  3. We understand that the Notes have not been registered under
the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of
any investor account for which we are purchasing Notes that we will not prior to
the date (the "RESALE RESTRICTION TERMINATION DATE") that is two years after the
later of the original issuance of the Note and the last date on which the
Company or any affiliate of the Company was the owner of such Notes (or any
predecessor thereto) offer, sell or otherwise transfer such Notes except (a) to
the Company or any subsidiary of the Company, (b) inside the United States to a
"qualified institutional buyer" in compliance with Rule 144A under the
Securities Act (c) inside the United States to an "institutional accredited
investor" as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act
that, prior to such transfer, furnishes (or has furnished on its behalf by a
U.S. broker-dealer) to the Trustee a signed letter substantially in the form of
this letter (d) outside the United States in an offshore transaction in
compliance with Rule 904 under the Securities Act (e) pursuant to any other
available exemption from the registration requirements of the Securities Act or
(f) pursuant to an effective registration statement under the Securities Act. We
acknowledge that the Company and the Trustee reserve the right prior to any
offer, sale or other transfer prior to the Resale Restriction Termination Date
of the applicable Notes pursuant to clause (c) or (e) above to require the
delivery of an opinion of counsel, certification and/or other information
satisfactory to the Company and the Trustee.

                  We understand that the Trustee will not be required to accept
for registration of transfer any Notes acquired by us, except upon presentation
of evidence satisfactory to the Company and the Trustee that the foregoing
restrictions on transfer have been complied with. We further understand that any
Notes purchased by us will be in the form of definitive physical certificates
and that such certificates will bear a legend reflecting the substance of
paragraph 3 of this letter. We further agree to provide to any person acquiring
any of the Notes from us a notice advising such person that transfers of such
Notes are restricted as stated herein and that certificates representing such
Notes will bear a legend to that effect.

                  We represent that the Company and the Trustee and others are
entitled to rely upon the truth and accuracy of our acknowledgments,
representations and agreements set forth herein, and we agree to notify you
promptly in writing if any of our acknowledgments, representations or agreements
herein cease to be accurate and complete. You are also irrevocably authorized to
produce this letter or a copy hereof to any interested party in any
administrative or legal proceeding or official inquiry with respect to the
matters covered hereby.

                  We represent to you that we have full power to make the
foregoing acknowledgments, representations and agreements on our own behalf and
on behalf of any investor account for which we are acting as fiduciary agent.

                  As used herein, the terms "offshore transaction," "United
States" and "U.S. person" have the respective meanings given to them in
Regulation S under the Securities Act.

                  THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

principal amount of the Notes, we confirm that such sale has been effected

         our behalf reasonably believed that the transferee was outside the
         United States, or (b) the transaction was executed in, on or through
         the facilities of a designated off-shore securities market and neither
         we nor any person acting on our behalf knows that the transaction has
         been prearranged with a buyer in the United States;

                  (3) no directed selling efforts have been made in the United
         States in contravention of the requirements of Rule 903(a) or Rule
         904(a) of Regulation S, as applicable;

                  (4) the transaction is not part of a plan or scheme to evade
         the registration requirements of the Securities Act; and

                  (5) we have advised the transferee of the transfer
         restrictions applicable to the Notes.

                  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. Defined terms used herein without
