         "ATTRIBUTABLE DEBT" in respect of a sale and leaseback transaction

nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global

Company delivers to the Trustee notice from the Depositary that it is
unwilling or unable to continue to act as Depositary or that it is no longer
a clearing agency registered under the Exchange Act and, in either case, a
successor Depositary is not appointed by the Company within 120 days after

in (i) or (ii) above, Definitive Notes shall be issued in such names as the

Registrar of the instructions contained in the Letter of Transmittal delivered

               Note, a certificate from such Holder in the form of Exhibit C
               hereto, including the certifications in item (1)(d) thereof; or

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

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

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

         (f) EXCHANGE OFFER. Upon the occurrence of the Exchange Offer in
accordance with the Registration Rights Agreement, the Company shall issue and,
upon receipt of an Authentication Order in accordance with Section 2.02, the

aggregate principal amount equal to the principal amount of the beneficial
interests in the Restricted Global Notes tendered for acceptance by Persons that
certify in the applicable Letters of Transmittal that (x) they are not
broker-dealers, (y) they are not participating in a distribution of the Exchange
Notes and (z) they are not affiliates (as defined in Rule 144) of the Company,
and accepted for exchange in the Exchange Offer and (ii) Definitive Notes in an
aggregate principal amount equal to the principal amount of the Restricted
Definitive Notes accepted for exchange in the Exchange Offer. Concurrently with
the issuance of such Notes, the Trustee shall cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and
the Company shall execute and the Trustee shall authenticate and deliver to the
Persons designated by the Holders of Definitive Notes so accepted Definitive
Notes in the appropriate principal amount.

         (g) LEGENDS. The following legends shall appear on the face of all
Global Notes and Definitive Notes issued under this Indenture unless
specifically stated otherwise in the applicable provisions of this Indenture.

         (i) PRIVATE PLACEMENT LEGEND.

         (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.06 (and

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

         (i) GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

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

             (ii) No service charge shall be made to a holder of a beneficial
         interest in a Global Note or to a Holder of a Definitive Note for any
         registration of transfer or exchange, but the

                                      31

<PAGE>

         Company may require payment of a sum sufficient to cover any transfer
         tax or similar governmental charge payable in connection therewith
         (other than any such transfer taxes or similar governmental charge
         payable upon exchange or transfer pursuant to Sections 2.10, 3.06,
         3.09, 4.10, 4.15 and 9.05 hereof).

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

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

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

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

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

             (viii) All certifications, certificates and Opinions of Counsel
         required to be submitted to the Registrar pursuant to this Section 2.06
         to effect a registration of transfer or exchange may be submitted by
         facsimile.

SECTION 2.07.     REPLACEMENT NOTES.

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

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

                                      32

SECTION 2.08.     OUTSTANDING NOTES.

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

         If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

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

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

SECTION 2.09.     TREASURY NOTES.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, waiver or consent,
only Notes that the Trustee knows are so owned shall be so disregarded.

SECTION 2.10.     TEMPORARY NOTES.

         Until certificates representing Notes are ready for delivery, the
Company may prepare and the Trustee, upon receipt of an Authentication Order,
shall authenticate temporary Notes. Temporary Notes shall be substantially in
the form of certificated Notes but may have variations that the Company
considers appropriate for temporary Notes and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate definitive Notes in exchange for temporary Notes.

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

SECTION 2.11.     CANCELLATION.

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

                                      33

SECTION 2.12.     DEFAULTED INTEREST.

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

                                   ARTICLE 3.
                            REDEMPTION AND PREPAYMENT

SECTION 3.01.     NOTICES TO TRUSTEE.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,
at least 30 days but not more than 60 days before a redemption date, an
Officers' Certificate setting forth (i) the clause of this Indenture pursuant to
which the redemption shall occur, (ii) the redemption date, (iii) the principal
amount of Notes to be redeemed and (iv) the redemption price.

SECTION 3.02.     SELECTION OF NOTES TO BE REDEEMED.

         If less than all of the Notes are to be redeemed or purchased in an
offer to purchase at any time, the Trustee shall select the Notes to be redeemed
or purchased among the Holders of the Notes as follows: (1) if the Notes are
listed on any national securities exchange, in compliance with the requirements
of the principal national securities exchange on which the Notes are listed; or
(2) if the Notes are not listed on any national securities exchange, on a pro
rata basis, by lot or by such method as the Trustee deems fair and appropriate.
In the event of partial redemption by lot, the particular Notes to be redeemed
shall be selected, unless otherwise provided herein, not less than 30 nor more
than 60 days prior to the redemption date by the Trustee from the outstanding
Notes not previously called for redemption.

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

SECTION 3.03.     NOTICE OF REDEMPTION.

         Subject to the provisions of Section 3.09 hereof, at least 30 days but
not more than 60 days before the redemption date, the Company shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Notes are to be redeemed at its registered address, except that redemption
notices may be mailed more than 60 days prior to the redemption date if the
notice is issued in connection with a defeasance of the Notes or a satisfaction
and discharge of this Indenture.

                                      34

<PAGE>

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

        (a) the redemption date;

        (b) the redemption price;

        (c) if any Note is being redeemed in part only, the portion of the
principal amount of such Note to be redeemed and that, after the redemption
date upon surrender of such Note, a new Note or Notes in principal amount
equal to the unredeemed portion shall be issued in the name of the Holder of
such original Note upon cancellation of the original Note;

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

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

        (f) that, unless the Company defaults in making such redemption
payment, interest on Notes or portions of them called for redemption ceases to
accrue on and after the redemption date;

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

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

         At the Company's written request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the
Company shall have delivered to the Trustee, at least 60 days prior to the
redemption date, an Officers' Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as provided
in the preceding paragraph.

SECTION 3.04.     EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is mailed in accordance with Section 3.03
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. Notices of redemption may not be
conditional.

SECTION 3.05.     DEPOSIT OF REDEMPTION PRICE.

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

         If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Company to comply with the preceding

                                       35

<PAGE>

paragraph, interest shall be paid on the unpaid principal, from the
redemption date until such principal is paid, and to the extent lawful on any
interest not paid on such unpaid principal, in each case at the rate provided
in the Notes and in Section 4.01 hereof.

SECTION 3.06.     NOTES REDEEMED IN PART.

         Upon surrender of a Note that is redeemed in part, the Company shall
issue and, upon the Company's written request, the Trustee shall authenticate
for the Holder at the expense of the Company a new Note equal in principal
amount to the unredeemed portion of the Note surrendered.

SECTION 3.07.     OPTIONAL REDEMPTION.

         (a) Except as set forth in clause (b) of this Section 3.07, the Company
shall not have the option to redeem the Notes pursuant to this Section 3.07
prior to June 1, 2006. Thereafter, the Company shall have the option to redeem
all or part of the Notes upon not less that 30 nor more than 60 days' notice, at
the redemption prices (expressed as percentages of principal amount) set forth
below plus accrued and unpaid interest and Special Interest thereon, if any, to
the applicable redemption date, if redeemed during the twelve-month period

more occasions redeem up to 35% of the aggregate principal amount of Notes
originally issued at a redemption price of 109% of the principal amount thereof,
plus accrued and unpaid interest and Special Interest thereon, if any, to the
redemption date, with the net cash proceeds of one or more Equity Offerings;
PROVIDED that (1) at least 65% of the aggregate principal amount of Notes
originally issued remains outstanding immediately after the occurrence of such
redemption (excluding Notes held by the Company and its Subsidiaries); and (2)
that such redemption occurs within 90 days of the date of the closing of such
Equity Offering.

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

SECTION 3.08.     MANDATORY REDEMPTION.

         The Company shall not be required to make mandatory redemption or
sinking fund payments with respect to the Notes.

SECTION 3.09.     OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

         In the event that, pursuant to Section 4.10 hereof, the Company shall
be required to commence an offer to all Holders of Notes and to all Holders of
other Indebtedness that is PARI PASSU with the Notes containing provisions
similar to those set forth in this Indenture with respect to offers to purchase
or redeem with the proceeds of sales of assets to purchase the maximum principal
amount of Notes and such other PARI PASSU Indebtedness that may be purchased out
of the Excess Proceeds (an "ASSET SALE OFFER"), it shall follow the procedures
specified below.

                                      36

<PAGE>

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

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

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

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

         (b) the Offer Amount, the purchase price and the Purchase Date;

         (c) that any Note not tendered or accepted for payment shall continue
to accrete or accrue interest;

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

         (e) that Holders electing to have a Note purchased pursuant to an Asset
Sale Offer may elect to have Notes purchased in integral multiples of $1,000
only;

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

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

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

                                      37

<PAGE>

offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

may lawfully do so) that it shall not at any time insist upon, plead, or in any

         continuing or would occur as a consequence of such Restricted Payment;
         and

                  (b) the Company would, at the time of such Restricted Payment
         and after giving pro forma effect thereto as if such Restricted Payment

         amount of all other Restricted Payments made by the Company and its
         Restricted Subsidiaries after the date of this Indenture (excluding
         Restricted Payments permitted by clauses (ii), (iii) and (iv) of the

         or from the issue or sale of convertible or exchangeable Disqualified
         Stock or convertible or exchangeable debt securities of the Company
         that have been converted into or exchanged for such Equity Interests
         (other than Equity Interests (or Disqualified Stock or debt securities)
         sold to a Subsidiary of the Company), plus (iii) to the extent that any
         Restricted Investment that was made after the date of this Indenture is
         sold for cash or otherwise liquidated or repaid for cash, the lesser of
         (A) the cash return of capital with respect to such Restricted
         Investment (less the cost of disposition, if any) and (B) the initial
         amount of such Restricted Investment, plus (iv) to the extent that any
         Unrestricted Subsidiary of the Company is redesignated as a Restricted
         Subsidiary of the Company after the date of this Indenture, the lesser
         of (x) the fair market value of the Company's Investment in such
         Subsidiary as of the date of such redesignation and (y) such fair
         market value as of the date on which such Subsidiary was originally
         designated as an Unrestricted Subsidiary.

         The preceding provisions shall not prohibit (i) the payment of any
dividend within 60 days after the date of declaration of the dividend, if at the
date of declaration the dividend payment would have complied with the provisions
of the indenture; (ii) the redemption, repurchase, retirement, defeasance or

management pursuant to any management equity subscription agreement, stock
option agreement or similar agreement; PROVIDED that the aggregate price paid
for all such repurchased, redeemed, acquired or retired Equity Interests may not
exceed $1.0 million in any twelve-month period; (vi) the

                                      41

fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Company or such
Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.
The fair market value of any assets or securities that are required to be valued
by this Section 4.07 shall be determined by the Board of Directors whose
resolution with respect thereto shall be delivered to the Trustee. The Board of
Directors' determination must be based on an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $15.0 million. Not later than the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'

SUBSIDIARIES.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (a) pay dividends or make any other distributions on

agreements governing Existing Indebtedness and Credit Facilities as in effect on
the date hereof and any amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings of those
agreements, PROVIDED that such amendments, modifications, restatements,
renewals, increases, supplements, refundings, replacements and/or refinancings
are not materially more restrictive, taken as a whole, with respect to such
dividend and other payment restrictions than those contained in those agreements
as of the date hereof, (ii) this Indenture, the Notes and the Subsidiary
Guarantees, (iii) applicable law or any applicable rule, regulation or order,
(iv) any instrument governing Indebtedness or Capital Stock of a Person acquired

incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired, PROVIDED that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of the Indenture to be incurred, (v)

course of business and consistent with past practices, (vi) purchase money

restricts distributions by that Restricted Subsidiary pending its sale or other
disposition, (viii) Permitted Refinancing Indebtedness, PROVIDED that the

Indebtedness are no more restrictive, taken as a whole, than those contained in
the agreements governing the Indebtedness being refinanced, (ix) Liens securing
Indebtedness otherwise permitted to be incurred under the provisions of

                                      42

SECTION 4.09.     INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "INCUR") any Indebtedness (including Acquired
Debt) and the Company shall not, and shall not permit any Guarantor to, issue
any Disqualified Stock and shall not permit any of its Restricted Subsidiaries
to issue any shares of preferred stock; PROVIDED, HOWEVER, that the Company or
any Guarantor may incur Indebtedness (including Acquired Debt) or issue
Disqualified Stock, if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock is issued would have been at
least 2.25 to 1, determined on a pro forma basis (including a pro forma
application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred or the Disqualified Stock had been issued, as the case may be,
at the beginning of such four-quarter period.

         The provisions of the first paragraph of this Section 4.09 shall not
apply to the incurrence of any of the following items of Indebtedness
(collectively, "PERMITTED DEBT"):

            (i)    the incurrence by the Company and any Guarantor of additional
         Indebtedness and letters of credit under Credit Facilities in an
         aggregate principal amount at any one time outstanding under this
         clause (i) (with letters of credit being deemed to have a principal
         amount equal to the maximum potential liability of the Company and
         its Restricted Subsidiaries thereunder) not to exceed $125.0
         million, LESS the aggregate amount of all Net Proceeds of Asset
         Sales applied by the Company or any of its Restricted Subsidiaries
         to repay any Indebtedness under a Credit Facility and effect a
         corresponding commitment reduction thereunder pursuant to Section

         Subsidiaries of the Existing Indebtedness;

         Indebtedness represented by the Notes and the related Subsidiary
         Guarantees to be issued on the date of this Indenture and the
         Exchange Notes and the related Subsidiary Guarantees to be issued
         pursuant to the Registration Rights Agreement;

            (iv)  the incurrence by the Company or any of its Restricted
         Subsidiaries that is a Guarantor of Indebtedness represented by
         Capital Lease Obligations, mortgage financings or purchase money
         obligations, in each case, incurred for the purpose of financing all
         or any part of the purchase price or cost of construction or
         improvement of property, plant or equipment used in the business of
         the Company or such Restricted Subsidiary, in an aggregate principal
         amount not to exceed $10.0 million at any time outstanding;

            (v)   the incurrence by the Company or any of its Restricted
         Subsidiaries of Permitted Refinancing Indebtedness in exchange for,
         or the net proceeds of which are used to refund, refinance or
         replace Indebtedness (other than intercompany Indebtedness) that was
         permitted by

                                      43

<PAGE>

         this Indenture to be incurred under the first paragraph of this
         Section 4.09 or clauses (ii), (iii) or (iv) of this paragraph;

            (vi)  the incurrence by the Company or any Guarantor of
         intercompany Indebtedness between or among the Company and any
         Guarantor; PROVIDED, HOWEVER, that:

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

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

            (vii) the issuance by the Company or any Guarantor of preferred
         stock solely to or among the Company and any Guarantor; PROVIDED,
         HOWEVER, that:

                  (A) any subsequent issuance or transfer of Equity Interests
            that results in any such preferred stock being held by a Person
            other than the Company or a Guarantor; and

                  (B) any sale or other transfer of any such preferred stock
            to a Person that is not either the Company or a Guarantor will be
            deemed, in each case, to constitute an issuance of such preferred
            stock by the Company or such Guarantor, as the case may be, that
            was not permitted by this clause (vii);

            (viii) the incurrence by the Company or any of its Restricted
         Subsidiaries of Hedging Obligations;

            (ix)   the guarantee by the Company or any of the Guarantors of
         Indebtedness of the Company or a Guarantor; PROVIDED that the
         underlying Indebtedness was permitted to be incurred by another
         provision of this Section 4.09; and

            (x)    the incurrence by the Company or any of its Restricted
         Subsidiaries of additional Indebtedness in an aggregate principal
         amount (or accreted value, as applicable) at any time outstanding,
         including all Permitted Refinancing Indebtedness incurred to refund,
         refinance or replace any Indebtedness incurred pursuant to this
         clause (x), not to exceed $25.0 million at any time outstanding.

         For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (i) through (x) above,
or is entitled to be incurred pursuant to the first paragraph of this Section
4.09, the Company shall, in its sole discretion, classify such item of
Indebtedness on the date of its incurrence, or later reclassify all or a portion
of such item of Indebtedness, in any manner that complies with this Section 4.09
and such item of Indebtedness shall be treated as having been incurred pursuant
to only one of such clauses or pursuant to the first paragraph of this Section
4.09. Indebtedness under Credit Facilities outstanding on the date on which
Notes are first issued and authenticated under this Indenture

                                      44

<PAGE>

will be deemed to have been incurred on such date in reliance on the
exception provided by clause (i) of the definition of Permitted Debt.

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

         The maximum amount of Indebtedness that the Company or one of its
Restricted Subsidiaries may incur pursuant this Section 4.09 shall not be deemed
to be exceeded, with respect to any outstanding Indebtedness, due solely to
fluctuations in currency exchange rates.

SECTION 4.10.     ASSET SALES.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: (a) the Company (or the
Restricted Subsidiary, as the case may be) receives consideration at the time of
such Asset Sale at least equal to the fair market value of the assets or Equity
Interests issued or sold or otherwise disposed of; (b) in the case of Asset
Sales for consideration exceeding $5.0 million, the fair market value is
determined by the Company's Board of Directors and evidenced by a resolution of
the Board of Directors set forth in an Officers' Certificate delivered to the
Trustee; and (c) at least 75% of the consideration received in the Asset Sale by
the Company or such Restricted Subsidiary is in the form of cash. For purposes
of this provision, each of the following will be deemed to be cash: (i) any
liabilities, as shown on the Company's or such Restricted Subsidiary's most
recent balance sheet or in the notes thereto, of the Company or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by
the transferee of any such assets pursuant to a customary novation agreement
that releases the Company or such Restricted Subsidiary from further liability;
and (ii) any securities, notes or other obligations received by the Company or
any such Restricted Subsidiary from such transferee that are contemporaneously,
subject to ordinary settlement periods, converted by the Company or such
Restricted Subsidiary into cash, to the extent of the cash received in that
conversion. A transfer of assets by the Company to a Wholly Owned Restricted
Subsidiary or by a Wholly Owned Restricted Subsidiary to the Company or to
another Wholly Owned Restricted Subsidiary, and an issuance of Equity Interests
by a Wholly Owned Restricted Subsidiary to the Company or to another Wholly
Owned Restricted Subsidiary, shall not be deemed to be an Asset Sale. Any
Restricted Payment that is permitted by Section 4.07 hereof will not be deemed
to be an Asset Sale.

         Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply the Net Proceeds, at its option, either (a) to repay
Senior Debt and, if the Senior Debt repaid is revolving credit Indebtedness, to
correspondingly reduce commitments with respect thereto, (b) to acquire all or
substantially all of the assets of, or a majority of the Voting Stock of,
another Permitted Business, (c) to make a capital expenditure, or (d) to acquire
other long-term assets that are used or useful in a Permitted Business. Pending
the final application of any such Net Proceeds, the Company may temporarily
reduce revolving credit borrowings or otherwise invest the Net Proceeds in any
manner that is not prohibited by this Indenture. Any Net Proceeds from Asset
Sales that are not applied or invested as provided in the first sentence of this
paragraph will be deemed to constitute "EXCESS PROCEEDS." Within ten Business
Days of each date on which the aggregate amount of Excess Proceeds exceeds $10
million, the Company shall make an Asset Sale Offer pursuant to Section 3.09
hereof to purchase the maximum principal amount of Notes and such other PARI
PASSU Indebtedness that may be purchased out of the Excess Proceeds. The offer
price in any Asset Sale Offer will be equal to 100% of the principal amount

                                      45

<PAGE>

plus accrued and unpaid interest and Special Interest thereon, if any, to the
date of purchase, in accordance with the procedures set forth in Section 3.09
hereof, and will be payable in cash. If any Excess Proceeds remain after
consummation of an Asset Sale Offer, the Company may use those Excess
Proceeds for any purpose not otherwise prohibited by this Indenture. Upon
completion of such offer to purchase, the amount of Excess Proceeds will be
deemed to be reset at zero.

SECTION 4.11.     TRANSACTIONS WITH AFFILIATES.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "AFFILIATE TRANSACTION"), unless
(a) such Affiliate Transaction is on terms that are no less favorable to the
Company or the relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (b) the Company delivers to the Trustee
(i) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $1.0 million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (a) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board of Directors and (ii) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $15.0 million, an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal or investment banking firm of national
standing.

         The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of the prior paragraph of
this Section 4.11: (i) any employment agreement, employee benefit arrangement,
stock option grant or similar contract entered into by the Company or any of its
Restricted Subsidiaries in the ordinary course of business and consistent with
the past practice of the Company or such Restricted Subsidiary, (ii)
transactions between or among the Company and/or its Restricted Subsidiaries,
(iii) transactions with a Person that is an Affiliate of the Company where such
affiliation arises solely because the Company owns an Equity Interest in, or
controls, such Person, (iv) payment of reasonable directors fees and amounts
paid in indemnification to Persons who are not otherwise Affiliates of the
Company, (v) sales of Equity Interests (other than Disqualified Stock) to
Affiliates of the Company, and (vi) Restricted Payments that are permitted under
Section 4.07 hereof.

SECTION 4.12.     LIENS.

         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, create, incur, assume or suffer to exist any Lien of any
kind securing Indebtedness, Attributable Debt or trade payables on any asset now
owned or hereafter acquired, or any income or profits therefrom or assign or
convey any right to receive income therefrom, except Permitted Liens.

SECTION 4.13.     BUSINESS ACTIVITIES.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in any business other than Permitted Businesses, except
to such extent as would not be material to the Company and its Restricted
Subsidiaries taken as a whole.

                                      46

SECTION 4.14.     CORPORATE EXISTENCE.

         Subject to Article 5 hereof, the Company shall do or cause to be done
all things necessary to preserve and keep in full force and effect (i) its
corporate existence, and the corporate, partnership or other existence of each
of its Subsidiaries, in accordance with the respective organizational documents
(as the same may be amended from time to time) of the Company or any such
Subsidiary and (ii) the rights (charter and statutory), licenses and franchises
of the Company and its Subsidiaries; PROVIDED, HOWEVER, that the Company shall
not be required to preserve any such right, license or franchise, or the
corporate, partnership or other existence of any of its Subsidiaries, if the
Board of Directors shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company and its Subsidiaries,
taken as a whole, and that the loss thereof is not adverse in any material
respect to the Holders of the Notes.

SECTION 4.15.     OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

         (a) Upon the occurrence of a Change of Control, the Company shall make
an offer (a "CHANGE OF CONTROL OFFER") to each Holder to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Special Interest thereon, if any, to the date of
purchase (the "CHANGE OF CONTROL PAYMENT"). Within 15 Business Days following
any Change of Control, the Company shall mail a notice to each Holder stating:
(1) that the Change of Control Offer is being made pursuant to this Section 4.15
and that all Notes tendered will be accepted for payment; (2) the purchase price
and the purchase date, which shall be no earlier than 30 days and no later than
60 days from the date such notice is mailed (the "CHANGE OF CONTROL PAYMENT
DATE"); (3) that any Note not tendered will continue to accrue interest; (4)
that, unless the Company defaults in the payment of the Change of Control
Payment, all Notes accepted for payment pursuant to the Change of Control Offer
shall cease to accrue interest after the Change of Control Payment Date; (5)
that Holders electing to have any 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 Notes completed, to
the Paying Agent at the address specified in the notice prior to the close of
business on the third Business Day preceding the Change of Control Payment Date;
(6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day
preceding the Change of Control Payment Date, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of Notes delivered for purchase, and a statement that such Holder is
withdrawing his election to have the Notes purchased; and (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, which
unpurchased portion must be equal to $1,000 in principal amount or an integral
multiple thereof. The Company shall 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 in connection with a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.15, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the provisions of this Section 4.15 by virtue of such
conflict.

         (b) On the Change of Control Payment Date, the Company shall, to the
extent lawful, (1) accept for payment all Notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Paying Agent shall promptly mail to each Holder

                                      47

<PAGE>

of Notes so tendered payment in an amount equal to the purchase price for the
Notes, and the Trustee shall promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered by such Holder, if
any; PROVIDED, that each such new Note shall be in a principal amount of
$1,000 or an integral multiple thereof. The Company shall publicly announce
the results of the Change of Control Offer on or as soon as practicable after
the Change of Control Payment Date.

         (c) Notwithstanding anything to the contrary in this Section 4.15, the
Company shall not be required to make a Change of Control Offer upon a Change of
Control if a third party makes the Change of Control Offer in the manner, at the
times and otherwise in compliance with the requirements set forth in this
Section 4.15 and Section 3.09 hereof and all other provisions of this Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

SECTION 4.16.     NO SENIOR SUBORDINATED DEBT.

         Notwithstanding the provisions of Section 4.09 hereof, (i) the Company
shall not incur, create, issue, assume, guarantee or otherwise become liable for
any Indebtedness that is subordinate or junior in right of payment to any Senior
Debt and senior in any respect in right of payment to the Notes, and (ii) no
Guarantor shall incur create, issue, assume, guarantee or otherwise become
liable for any Indebtedness that is subordinated or junior in right of payment
to the Senior Debt of such Guarantor and senior in any respect in right of
payment to such Guarantor's Subsidiary Guarantee.

SECTION 4.17.     LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; PROVIDED that
the Company or any Restricted Subsidiary may enter into a sale and leaseback
transaction if (i) the Company or that Restricted Subsidiary, as applicable,
could have (a) incurred Indebtedness in an amount equal to the Attributable Debt
relating to such sale and leaseback transaction pursuant to the Fixed Charge
Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof and
(b) incurred a Lien to secure such Indebtedness pursuant to the provisions of
Section 4.12 hereof, (ii) the gross cash proceeds of such sale and leaseback
transaction are at least equal to the fair market value, as determined in good
faith by the Board of Directors and set forth in an Officers' Certificate
delivered to the Trustee, of the property that is the subject of such sale and
leaseback transaction and (iii) the transfer of assets in such sale and
leaseback transaction is permitted by, and the Company applies the proceeds of
such transaction in compliance with, Section 4.10 hereof.

SECTION 4.18.     PAYMENTS FOR CONSENT.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, pay or cause to be paid any consideration whether by
way of interest, fee or otherwise, to or for the benefit of any Holder of Notes
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of the Indenture or the Notes unless such consideration is offered
to be paid and/or is paid to all Holders of the Notes that consent, waive or
agree to amend in the time frame set forth in the solicitation documents
relating to such consent, waiver or agreement.

SECTION 4.19.     ADDITIONAL SUBSIDIARY GUARANTEES.

         If the Company or any of its Restricted Subsidiaries shall acquire or
create another Domestic Subsidiary after the date of this Indenture, then such
newly acquired or created Domestic Subsidiary shall become a Guarantor and
execute a Subsidiary Guarantee in the form of a Supplemental Indenture and

                                      48

<PAGE>

deliver an Opinion of Counsel satisfactory to the Trustee in accordance with the
terms of this Indenture within ten Business Days of the date on which it was
acquired or created; PROVIDED, however, that the foregoing shall not apply to
Subsidiaries that have properly been designated as Unrestricted Subsidiaries in
accordance with this Indenture for so long as they continue to constitute
Unrestricted Subsidiaries. The form of such Subsidiary Guarantee is attached as
Exhibit E hereto.

SECTION 4.20.     DESIGNATION OF RESTRICTED AND UNRESTRICTED SUBSIDIARIES.

         The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a
Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate
fair market value of all outstanding Investments owned by the Company and its
Restricted Subsidiaries in the Subsidiary properly designated shall be deemed to
be an Investment made as of the time of the designation and shall reduce the
amount available for Restricted Payments under the first paragraph of Section
4.07 hereof or, if eligible, Permitted Investments that are permitted by clause
(8) of the definition of "Permitted Investments," as determined by the Company.
That designation shall only be permitted if the Investment would be permitted at
that time and if the Restricted Subsidiary otherwise meets the definition of an
Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted
Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a
Default.

         Upon any consolidation or merger, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the assets
of the Company in accordance with Section 5.01 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, lease, conveyance or other disposition is
made shall succeed to, and be substituted for (so that from and after the date
of such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Company" shall refer instead to
the successor corporation and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such

principal of and interest on the Notes except in the case of a sale, assignment,
transfer, conveyance or other disposition of all of the Company's assets that
meets the requirements of Section 5.01 hereof.

SECTION 6.02.     ACCELERATION.

         If any Event of Default (other than an Event of Default specified in
clause (h) or (i) of Section 6.01 hereof with respect to the Company, any
Restricted Subsidiary that is a Significant Subsidiary or any group of
Restricted Subsidiaries that taken as a whole, would constitute a Significant
Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Notes may declare all the Notes to
be due and payable immediately. Upon any such declaration, the Notes shall
become due and payable immediately. Notwithstanding the foregoing, if an Event
of Default

                                      51

<PAGE>

specified in clause (h) or (i) of Section 6.01 hereof occurs with respect to
the Company, any of its Restricted Subsidiaries that is a Significant
Subsidiary or any group of Restricted Subsidiaries that, taken as a whole,
would constitute a Significant Subsidiary, all outstanding Notes shall be due
and payable immediately without further action or notice. The Holders of a
majority in aggregate principal amount of the then outstanding Notes by
written notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if the rescission would not conflict with
any judgment or decree and if all existing Events of Default (except
nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

         If an Event of Default occurs on or after June 1, 2006 by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the Company
with the intention of avoiding payment of the premium that the Company would
have had to pay if the Company then had elected to redeem the Notes pursuant to
Section 3.07 hereof, then, upon acceleration of the Notes, an equivalent premium
shall also become and be immediately due and payable, to the extent permitted by
law, anything in this Indenture or in the Notes to the contrary notwithstanding.
If an Event of Default occurs prior to June 1, 2006 by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding the prohibition on redemption of the Notes prior to
such date, then, upon acceleration of the Notes, an additional premium shall
also become and be immediately due and payable in an amount, for each of the
years beginning on ______ of the years set forth below, as set forth below
(expressed as a percentage of the principal amount of the Notes on the date of
payment that would otherwise be due but for the provisions of this sentence):

SECTION 6.03.     OTHER REMEDIES.

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

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

SECTION 6.04.     WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in aggregate principal amount of
the then outstanding Notes by notice to the Trustee may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Special Interest, if any, or interest
on, the Notes (including in connection with an offer to purchase) (PROVIDED,
HOWEVER, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration).
Upon any such waiver, such

                                     52

<PAGE>

Default shall cease to exist, and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose of this Indenture; but
no such waiver shall extend to any subsequent or other Default or impair any
right consequent thereon.

SECTION 6.05.     CONTROL BY MAJORITY.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it, PROVIDED that the Trustee may require indemnity satisfactory to
it to be furnished prior to taking such actions. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture that the
Trustee determines may be unduly prejudicial to the rights of other Holders of
Notes or that may involve the Trustee in personal liability.

SECTION 6.06.     LIMITATION ON SUITS.

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

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

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

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

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

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

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

SECTION 6.07.     RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Special Interest,
if any, and interest on the Note, on or after the respective due dates expressed
in the Note (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

SECTION 6.08.     COLLECTION SUIT BY TRUSTEE.

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

<PAGE>

SECTION 6.09.     TRUSTEE MAY FILE PROOFS OF CLAIM.

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

SECTION 6.10.     PRIORITIES.

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

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

                  SECOND: to Holders of Notes for amounts due and unpaid on the
         Notes for principal, premium and Special Interest, if any, and
         interest, ratably, without preference or priority of any kind,
         according to the amounts due and payable on the Notes for principal,
         premium and Special Interest, if any and interest, respectively; and

                  THIRD: to the Company or to such party as a court of competent
         jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders of Notes 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 a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to

                                       54

<PAGE>

Section 6.07 hereof, or a suit by Holders of more than 10% in principal
amount of the then outstanding Notes.

                                     TRUSTEE

SECTION 7.01.     DUTIES OF TRUSTEE.

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

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

             (i) the duties of the Trustee shall be determined solely by the
         express provisions of this Indenture and the Trustee need perform only
         those duties that are specifically set forth in this Indenture and no
         others, and no implied covenants or obligations shall be read into this
         Indenture against the Trustee, and the permissive right of the Trustee
         shall not be construed as a duty; and

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

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

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

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

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

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

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

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

                                       55

<PAGE>

SECTION 7.02.     RIGHTS OF TRUSTEE.

         (a) The Trustee may conclusively rely upon any document believed by it
to be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in the document and may
accept the same as conclusive evidence of the truth and accuracy of such
statement or the correctness of such opinion.

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

         (c) The Trustee may act through its attorneys and agents and shall not
be responsible for the misconduct or negligence of any agent appointed with due
care. Any expenses incurred shall be reimbursed by the Company.

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

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

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

         (g) The Trustee may appoint a co-Trustee if it so desires.

         (h) The Trustee shall not be liable for any action taken or omitted by
it in good faith on the direction of the Holders of not less than a majority in
principal amount of the then outstanding Notes as to the time, method and place
of conducting any proceedings for any remedy available to the Trustee or the
exercise of any power conferred by this Indenture.

SECTION 7.03.     INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the Commission
for permission to continue as trustee or resign. Any Agent may do the same with
like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11
hereof.

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, the Notes, any supplements
thereto or instrument of further assurance; it shall not be accountable for the
Company's use of the proceeds from the Notes or any money paid to the Company or
upon the Company's direction under any provision of this Indenture; it shall not
be

                                       56

<PAGE>

responsible for the use or application of any money received by any Paying
Agent other than the Trustee; and it shall not be responsible for any statement
or recital herein or any statement in the Notes or any other document in
connection with the sale of the Notes or pursuant to this Indenture other than
its certificate of authentication.

SECTION 7.05.     NOTICE OF DEFAULTS.

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

         The Trustee shall not be required to take notice or be deemed to have
notice of any Event of Default, except failure of the obligor to cause to be
made any of the payments to the Trustee required to be made, unless the Trustee
shall be specifically notified by a writing of such default by the Company or by
the Holders of at least 25% in aggregate principal amount of the then
outstanding Notes delivered to the Corporate Trust Office of the Trustee and, in
the absence of such notice so delivered the Trustee may conclusively assume no
default exists.

SECTION 7.06.     REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

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

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

SECTION 7.07.     COMPENSATION AND INDEMNITY.

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

         The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the
costs and expenses of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
the Company or any Holder or any other person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to
the extent any such loss, liability or expense may be attributable to its
negligence or bad faith. The Trustee shall notify the Company promptly of any
claim for which it may

                                       57

<PAGE>

seek indemnity. Failure by the Trustee to so notify the Company shall not
relieve the Company of its obligations hereunder. The Company shall defend
the claim and the Trustee shall cooperate in the defense. The Trustee may
have separate counsel and the Company shall pay the reasonable fees and
expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

         The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

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

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

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

SECTION 7.08.     REPLACEMENT OF TRUSTEE.

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

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

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

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

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

         (d) the Trustee becomes incapable of acting.

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

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

                                       58

<PAGE>

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

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

SECTION 7.09.     SUCCESSOR TRUSTEE BY MERGER, ETC.

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

SECTION 7.10.     ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder that is a corporation
organized and doing business under the laws of the United States of America or
of any state thereof that is authorized under such laws to exercise corporate
trustee power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50 million
as set forth in its most recent published annual report of condition.

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

SECTION 7.11.     PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee is subject to 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 Notes shall thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture, such
Notes, and such Subsidiary Guarantees shall be unaffected thereby. In addition,
upon the Company's exercise under Section 8.01 hereof of the option applicable
to this Section 8.03 hereof, subject to the satisfaction of the conditions set
forth in Section 8.04 hereof, Sections 6.01(c) through 6.01(f) hereof shall not
constitute Events of Default.

SECTION 8.04.     CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

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

         In order to exercise either Legal Defeasance or Covenant Defeasance:

                                       60

<PAGE>

         (a) the Company must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders of the Notes, cash in United States dollars,
non-callable Government Securities, or a combination of cash in United States
dollars and non-callable Government Securities, in such amounts as will be
sufficient, in the opinion of a nationally recognized firm of independent public
accountants, to pay the principal of, and interest and premium and Special
Interest, if any, on the outstanding Notes on the stated date for payment
thereof or on the applicable redemption date, as the case may be, and the
Company shall specify whether the Notes are being defeased to maturity or to a
particular redemption date;

         (b) in the case of an election under Section 8.02 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

         (c) in the case of an election under Section 8.03 hereof, the Company
shall have delivered to the Trustee an Opinion of Counsel in the United States
reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

         (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Indebtedness all or a portion of the proceeds
of which will be used to defease the Notes pursuant to this Article 8
concurrently with such incurrence) or insofar as Sections 6.01(h) or 6.01(i)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

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

         (f) the Company shall have delivered to the Trustee an Opinion of
Counsel (which may be subject to customary exceptions) to the effect that on the
91st day following the deposit, the trust funds will not be subject to the
effect of any applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors' rights generally;

         (g) 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 of Notes over any other creditors of the Company or
with the intent of defeating, hindering, delaying or defrauding any other
creditors of the Company or others; and

         (h) 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.

                                       61

SECTION 8.05.     DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN TRUST;
                  OTHER MISCELLANEOUS PROVISIONS.

         Subject to Section 8.06 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the
"Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and 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 against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

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

SECTION 8.06.     REPAYMENT TO COMPANY.

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

SECTION 8.07.     REINSTATEMENT.

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

                                        62

<PAGE>

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

                                     ARTICLE 9.
                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.     WITHOUT CONSENT OF HOLDERS OF NOTES.

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

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

         (b) to provide for uncertificated Notes in addition to or in place of
certificated Notes or to alter the provisions of Article 2 hereof (including the
related definitions) in a manner that does not materially adversely affect any
Holder;

         (c) to provide for the assumption of the Company's obligations to the
Holders of the Notes by a successor to the Company pursuant to Article 5 hereof;

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

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

         (f) to provide for the issuance of Additional Notes in accordance with
the limitations set forth in this Indenture as of the date hereof; or

         (g) to allow any Guarantor to execute a supplemental indenture and/or a
Subsidiary Guarantee with respect to the Notes.

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

SECTION 9.02.     WITH CONSENT OF HOLDERS OF NOTES.

         Except as provided below in this Section 9.02, the Company and the
Trustee may amend or supplement this Indenture (including Section 3.09, 4.10 and
4.15 hereof) and the Notes with the consent of the Holders of at least a
majority in principal amount of the Notes (including Additional Notes, if any)
then outstanding voting as a single class (including, without limitation,
consents obtained in connection with a purchase of, or a tender offer or
exchange offer for, the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, or interest on the
Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this Indenture or the

                                       63

<PAGE>

Notes may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding Notes (including Additional Notes,
if any) voting as a single class (including, without limitation, consents
obtained in connection with a purchase of, or tender offer or exchange offer
for, the Notes). Section 2.08 shall determine which Notes are considered to
be "outstanding" for purposes of this Section 9.02.

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

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

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

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

         (b) reduce the principal of or change the fixed maturity of any Note or
alter or waive any of the provisions with respect to the redemption of the Notes
except as provided with respect to Sections 3.09, 4.10 and 4.15 hereof;

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

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

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

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

                                        64

<PAGE>

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

         (h) make any change in Section 6.04 or 6.07 hereof or in the foregoing
amendment and waiver provisions; or

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

         In addition, any amendment to, or waiver of, Article 11 hereof that
adversely affects the rights of the Holders of Notes shall require the consent
of the Holders of at least 75% in aggregate principal amount of the Notes then
outstanding, voting as a single class, (including, without limitation, consents
obtained in connection with a purchase of, or a tender offer or exchange offer
for, the Notes).

SECTION 9.03.     COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.04.     REVOCATION AND EFFECT OF CONSENTS.

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

SECTION 9.05.     NOTATION ON OR EXCHANGE OF NOTES.

         The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall, upon receipt of an
Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

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

SECTION 9.06.     TRUSTEE TO SIGN AMENDMENTS, ETC.

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

                                  ARTICLE 10.
                              SUBSIDIARY GUARANTEES

SECTION 10.01.    GUARANTEE.

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

         The Guarantors hereby agree that their obligations hereunder shall be
unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any
waiver or consent by any Holder of the Notes with respect to any provisions
hereof or thereof, the recovery of any judgment against the Company, any action
to enforce the same or any other circumstance which might otherwise constitute a
legal or equitable discharge or defense of a guarantor. Each Guarantor hereby
waives diligence, presentment, demand of payment, filing of claims with a court
in the event of insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest, notice and all demands whatsoever
and covenant that this Subsidiary Guarantee shall not be discharged except by
complete performance of the obligations contained in the Notes and this
Indenture.

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

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

                                       66

<PAGE>

SECTION 10.02.    SUBORDINATION OF SUBSIDIARY GUARANTEE.

         The Obligations of each Guarantor under its Subsidiary Guarantee
pursuant to this Article 10 shall be junior and subordinated to the Senior
Guarantee of such Guarantor on the same basis as the Notes are junior and
subordinated to Senior Debt of the Company. For the purposes of the foregoing
sentence, the Trustee and the Holders shall have the right to receive and/or
retain payments by any of the Guarantors only at such times as they may receive
and/or retain payments in respect of the Notes pursuant to this Indenture,
including Article 11 hereof.

SECTION 10.03.    LIMITATION ON GUARANTOR LIABILITY.

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

SECTION 10.04.    EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEE.

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

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

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

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

         In the event that the Company creates or acquires any new Subsidiaries
subsequent to the date of this Indenture, if required by Section 4.24 hereof,
the Company shall cause such Subsidiaries to execute supplemental indentures to
this Indenture and Subsidiary Guarantees in accordance with Section 4.24 hereof
and this Article 10, to the extent applicable.

                                       67

<PAGE>

SECTION 10.05.    GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.

         Except as otherwise provided in Section 10.06, no Guarantor may
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person whether or not affiliated with such Guarantor
unless:

         (a) subject to Section 10.06 hereof, the Person formed by or surviving
any such consolidation or merger (if other than a Guarantor or the Company)
unconditionally assumes all the obligations of such Guarantor, pursuant to a
supplemental indenture in form and substance reasonably satisfactory to the
Trustee, under the Notes, the Indenture and the Subsidiary Guarantee on the
terms set forth herein or therein; and

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

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

         Except as set forth in Articles 4 and 5 hereof, and notwithstanding
clauses (a) and (b) above, nothing contained in this Indenture or in any of the
Notes shall prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or shall prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

SECTION 10.06.    RELEASES FOLLOWING SALE OF ASSETS.

         In the event of a sale or other disposition of all of the assets of any
Guarantor, by way of merger, consolidation or otherwise, or a sale or other
disposition of all to the capital stock of any Guarantor, in each case to a
Person that is not (either before or after giving effect to such transactions) a
Restricted Subsidiary of the Company, then such Guarantor (in the event of a
sale or other disposition, by way of merger, consolidation or otherwise, of all
of the capital stock of such Guarantor) or the corporation acquiring the
property (in the event of a sale or other disposition of all or substantially
all of the assets of such Guarantor) will be released and relieved of any
obligations hereunder and under its Subsidiary Guarantee; PROVIDED that the Net
Proceeds of such sale or other disposition are applied in accordance with the
applicable provisions of this Indenture, including without limitation Section
4.10 hereof. Upon delivery by the Company to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of this
Indenture, including without limitation Section 4.10 hereof, the Trustee shall
execute any documents reasonably required in order to evidence the release of
any Guarantor from its obligations under its Subsidiary Guarantee.

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

                                   ARTICLE 11.
                                  SUBORDINATION

SECTION 11.01.    AGREEMENT TO SUBORDINATE.

         The Company agrees, and each Holder by accepting a Note agrees, that
the Indebtedness evidenced by the Notes is subordinated in right of payment, to
the extent and in the manner provided in this Article 11, to the prior payment
in full of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt.

SECTION 11.02.    LIQUIDATION; DISSOLUTION; BANKRUPTCY.

         Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or any marshaling of the Company's
assets and liabilities:

                  (i) holders of Senior Debt shall be entitled to receive
         payment in full of all Obligations due in respect of such Senior Debt
         (including interest after the commencement of any such proceeding at
         the rate specified in the applicable Senior Debt) before Holders of the
         Notes shall be entitled to receive any payment with respect to the
         Notes (except that Holders may receive (A) Permitted Junior Securities
         and (B) payments and other distributions made from any defeasance trust
         created pursuant to Section 8.01 hereof); and

                  (ii) until all Obligations with respect to Senior Debt (as
         provided in clause (i) above) are paid in full, any distribution to
         which Holders would be entitled but for this Article 10 shall be made
         to holders of Senior Debt (except that Holders of Notes may receive (A)
         Permitted Junior Securities and (B) payments and other distributions
         made from any defeasance trust created pursuant to Section 8.01
         hereof), as their interests may appear.

SECTION 11.03.    DEFAULT ON DESIGNATED SENIOR DEBT.

         (a) The Company may not make any payment or distribution to the Trustee
or any Holder in respect of Obligations with respect to the Notes and may not
acquire from the Trustee or any Holder any Notes for cash or property (other
than (A) Permitted Junior Securities and (B) payments and other distributions
made from any defeasance trust created pursuant to Section 8.01 hereof) until
all principal and other Obligations with respect to the Senior Debt have been
paid in full if:

                  (i) a default in the payment of any principal or other
         Obligations with respect to Designated Senior Debt occurs and is
         continuing beyond any applicable grace period in the agreement,
         indenture or other document governing such Designated Senior Debt; or

                  (ii) a default, other than a payment default, on Designated
         Senior Debt occurs and is continuing that then permits holders of the
         Designated Senior Debt to accelerate its maturity and the Trustee
         receives a notice of the default (a "PAYMENT BLOCKAGE NOTICE") from a
         Person who may give it pursuant to Section 11.11 hereof. If the Trustee
         receives any such Payment Blockage Notice, no subsequent Payment
         Blockage Notice shall be effective for purposes of this Section unless
         and until (A) at least 360 days shall have elapsed since the
         effectiveness of the immediately prior Payment Blockage Notice and (B)
         all scheduled payments of principal, premium, if any, and interest on
         the Securities that have come due have been paid in full in cash.

                                       69

<PAGE>

         No nonpayment default that existed or was continuing on the date of
         delivery of any Payment Blockage Notice to the Trustee shall be, or be
         made, the basis for a subsequent Payment Blockage Notice unless such
         default shall have been waived for a period of not less than 90 days.

         (b) The Company may and shall resume payments on and distributions in
respect of the Notes and may acquire them upon the earlier of:

                  (i)      the date upon which the default is cured or
         waived, or

                  (ii) in the case of a default referred to in clause (ii) of
         Section 11.03(a) hereof, 179 days pass after notice is received if the
         maturity of such Designated Senior Debt has not been accelerated,

if this Article 11 otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

SECTION 11.04.    ACCELERATION OF SECURITIES.

         If payment of the Securities is accelerated because of an Event of
Default, the Company shall promptly notify holders of Senior Debt of the
acceleration.

SECTION 11.05.    WHEN DISTRIBUTION MUST BE PAID OVER.

         In the event that the Trustee or any Holder receives any payment of any
Obligations with respect to the Notes at a time when the Trustee or such Holder,
as applicable, has actual knowledge that such payment is prohibited by Section
11.03 hereof, such payment shall be held by the Trustee or such Holder, in trust
for the benefit of, and shall be paid forthwith over and delivered, upon written
request, to, the holders of Senior Debt as their interests may appear or their
Representative under the indenture or other agreement (if any) pursuant to which
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of all Obligations with respect to Senior Debt
remaining unpaid to the extent necessary to pay such Obligations in full in
accordance with their terms, after giving effect to any concurrent payment or
distribution to or for the holders of Senior Debt.

         With respect to the holders of Senior Debt, the Trustee undertakes to
perform only such obligations on the part of the Trustee as are specifically set
forth in this Article 11, and no implied covenants or obligations with respect
to the holders of Senior Debt 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 Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of Holders or the Company
or any other Person money or assets to which any holders of Senior Debt shall be
entitled by virtue of this Article 11, except if such payment is made as a
result of the willful misconduct or gross negligence of the Trustee.

SECTION 11.06.    NOTICE BY COMPANY.

         The Company shall promptly notify the Trustee and the Paying Agent in
writing of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes to violate this Article 11, but failure to
give such notice shall not affect the subordination of the Notes to the Senior
Debt as provided in this Article 11.

                                       70

<PAGE>

SECTION 11.07.    SUBROGATION.

         After all Senior Debt is paid in full and until the Notes are paid in
full, Holders of Notes shall be subrogated (equally and ratably with all other
Indebtedness PARI PASSU with the Notes) to the rights of holders of Senior Debt
to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the Holders of Notes have been applied to the
payment of Senior Debt. A distribution made under this Article 11 to holders of
Senior Debt that otherwise would have been made to Holders of Notes is not, as
between the Company and Holders, a payment by the Company on the Notes.

SECTION 11.08.    RELATIVE RIGHTS.

         This Article 11 defines the relative rights of Holders of Notes and
holders of Senior Debt. Nothing in this Indenture shall:

                  (i) impair, as between the Company and Holders of Notes, the
         obligation of the Company, which is absolute and unconditional, to pay
         principal of and interest on the Notes in accordance with their terms;

                  (ii) affect the relative rights of Holders of Notes and
         creditors of the Company other than their rights in relation to holders
         of Senior Debt; or

                  (iii) prevent the Trustee or any Holder of Notes from
         exercising its available remedies upon a Default or Event of Default,
         subject to the rights of holders and owners of Senior Debt to receive
         distributions and payments otherwise payable to Holders of Notes.

         If the Company fails because of this Article 11 to pay principal of or
interest on a Note on the due date, the failure is still a Default or Event of
Default.

SECTION 11.09.    SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

         No right of any holder of Senior Debt to enforce the subordination of
the Indebtedness evidenced by the Notes shall be impaired by any act or failure
to act by the Company or any Holder or by the failure of the Company or any
Holder to comply with this Indenture.

SECTION 11.10.    DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

         Whenever a distribution is to be made or a notice given to holders of
Senior Debt, the distribution may be made and the notice given to their
Representative.

         Upon any payment or distribution of assets of the Company referred to
in this Article 11, the Trustee and the Holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Holders
of Notes for the purpose of ascertaining the Persons entitled to participate in
such distribution, the holders of the Senior Debt and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 11.

SECTION 11.11.    RIGHTS OF TRUSTEE AND PAYING AGENT.

         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 that would prohibit the making

                                       71

<PAGE>

of any payment or distribution by the Trustee, and the Trustee and the Paying
Agent may continue to make payments on the Notes, unless the Trustee shall
have received at its Corporate Trust Office at least five Business Days prior
to the date of such payment written notice of facts that would cause the
payment of any Obligations with respect to the Notes to violate this Article
11. Only the Company or a Representative may give the notice. Nothing in this
Article 11 shall impair the claims of, or payments to, the Trustee under or
pursuant to Section 7.07 hereof.

         The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee. Any Agent may do
the same with like rights.

SECTION 11.12.    AUTHORIZATION TO EFFECT SUBORDINATION.

         Each Holder of Notes, by the Holder's acceptance thereof, authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination as provided in this
Article 11, and appoints the Trustee to act as such Holder's attorney-in-fact
for any and all such purposes. If the Trustee does not file a proper proof of
claim or proof of debt in the form required in any proceeding referred to in
Section 6.09 hereof at least 30 days before the expiration of the time to file
such claim, the Representatives are hereby authorized to file an appropriate
claim for and on behalf of the Holders of the Notes.

SECTION 11.13.    AMENDMENTS.

         The provisions of this Article 11 shall not be amended or modified
without the written consent of the holders of all Senior Debt.

                               ARTICLE 12.
                        SATISFACTION AND DISCHARGE

SECTION 12.01.    SATISFACTION AND DISCHARGE.

         This Indenture will be discharged and will cease to be of further
effect as to all Notes issued hereunder, when:

(1)      either:

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

         (b)      all Notes that have not been delivered to the Trustee for
                  cancellation have become due and payable by reason of the
                  making of a notice of redemption or otherwise or will become
                  due and payable within one year and the Company or any
                  Guarantor has irrevocably deposited or caused to be deposited
                  with the Trustee as trust funds in trust solely for the
                  benefit of the Holders, cash in U.S. dollars, non-callable
                  Government Securities, or a combination of cash in United
                  States dollars and non-callable Government Securities, in such
                  amounts as will be sufficient without consideration of any
                  reinvestment of interest, to pay and discharge the entire
                  indebtedness on the Notes not delivered to the Trustee for
                  cancellation for principal, premium and/or Special Interest,
                  if any, and accrued interest to the date of maturity or
                  redemption;

                                       72

<PAGE>

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

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

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

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

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

SECTION 12.02.    APPLICATION OF TRUST MONEY.

         Subject to the provisions of Section 8.06, all money deposited with the
Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in
accordance with the provisions of the Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as its
own Paying Agent) as the Trustee may determine, to the Persons entitled thereto,
of the principal (and premium, if any) and interest for whose payment such money
has been deposited with the Trustee; but such money need not be segregated from
other funds except to the extent required by law.

         If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 12.01 by reason of any legal
proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the
Company's and any Guarantor's obligations under this Indenture and the Notes
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 12.01; PROVIDED that if the Company has made any payment of principal
of, premium, if any, or interest on any Notes because of the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of
such Notes to receive such payment from the money or Government Securities held
by the Trustee or Paying Agent.

[INSERT THE GLOBAL NOTE LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS OF THE
INDENTURE]

[INSERT THE PRIVATE PLACEMENT LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS
OF THE INDENTURE]

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

         1. INTEREST. Lone Star Technologies, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this Note at
9.00% per annum from May 29, 2001 until maturity and shall pay the Special
Interest payable pursuant to Section 2 of the Registration Rights Agreement
referred to below. The Company will pay interest and Special Interest
semi-annually in arrears on June 1 and December 1 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of issuance; PROVIDED that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to
on the face hereof and the next succeeding Interest Payment Date, interest shall
accrue from such next succeeding Interest Payment Date; PROVIDED, FURTHER, that
the first Interest Payment Date shall be December 1, 2001. The Company shall pay
interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest and Special Interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30-day months.

         2. METHOD OF PAYMENT. The Company will pay interest on the Notes
(except defaulted interest) and Special Interest to the Persons who are
registered Holders of Notes at the close of business on May 15 or November 15,
as the case may be, next preceding the Interest Payment Date, even if such Notes
are canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.12 of the Indenture with respect to defaulted
interest. The Notes will be payable as to principal, interest, premium and
Special Interest, if any, at the office or agency of the Company maintained for
such purpose within the City and State of New York, or, at the option of the
Company, payment of interest and Special Interest may be made by check mailed to
the Holders at their addresses set forth in the register of Holders, and
PROVIDED that payment by wire transfer of immediately available funds will be
required with respect to principal of, interest on, premium and Special Interest
on, all Global Notes and all other Notes the Holders of which shall have
provided wire transfer instructions to the Company or the Paying Agent. Such
payment shall be in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts.

         3. PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank Minnesota,
National Association, the Trustee under the Indenture, will act as Paying Agent
and Registrar. The Company may change any Paying Agent or Registrar without
notice to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

         4. INDENTURE. The Company issued the Notes under an Indenture dated as
of May 29, 2001 ("Indenture") between the Company, the Guarantors thereto, and
the Trustee. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust

                                      A-2
<PAGE>

Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the indenture shall govern and be controlling.

         5. OPTIONAL REDEMPTION.

         (a) Except as set forth in subparagraph (b) of this Paragraph 5, the
Company shall not have the option to redeem the Notes prior to June 1, 2006.

<S>                                                                 <C>

to $1,000 or an integral multiple thereof) of each Holder's Notes at a purchase
price equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest Special Interest thereon, if any, to the date of purchase the
"Change of Control Payment"). Within 15 days following any Change of Control,
the Company shall mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture.

         (b) If the Company or a Subsidiary consummates any Asset Sales, within
ten Business Days of each date on which the aggregate amount of Excess Proceeds
exceeds $10 million, the Company shall commence an offer to all Holders of Notes
(as "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to purchase
the maximum principal amount of Notes (including any Additional Notes) and such
other PARI PASSU Indebtedness that may be purchased out of the Excess Proceeds
at an offer price in cash in an amount equal to 100% of the principal amount
thereof plus accrued and unpaid interest and Special Interest thereon, if any,
to the date of purchase, in accordance with the procedures set forth in the
Indenture. To the extent that the aggregate amount of Notes (including any
Additional Notes) and other

                                      A-3
<PAGE>

PARI PASSU Indebtedness tendered pursuant to an Asset Sale Offer is less than
the Excess Proceeds, the Company (or such Subsidiary) may use such deficiency
for any purpose not otherwise prohibited by the Indenture. If the aggregate
principal amount of Notes surrendered by Holders thereof and other PARI PASSU
Indebtedness tendered exceeds the amount of Excess Proceeds, the Trustee
shall select the Notes to be purchased on a PRO RATA basis. Holders of Notes
that are the subject of an offer to purchase will receive an Asset Sale Offer
from the Company prior to any related purchase date and may elect to have
such Notes purchased by completing the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Notes.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the redemption date to each Holder
whose Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions thereof
called for redemption.

         9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in

things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Company
need not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record

treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions,
the Indenture, the Subsidiary Guarantees or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the then outstanding Notes and Additional Notes, if any, voting as a
single class, and any existing default or compliance with any provision of the
Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes and Additional Notes,
if any, voting as a single class. Without the consent of any Holder of a Note,
the Indenture, the Subsidiary Guarantees or the Notes may be amended or
supplemented to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes, to
provide for the assumption of the Company's obligations to Holders of the Notes
in case of a merger or consolidation, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act, to provide for
the Issuance of Additional Notes in accordance with the limitations set forth in
the Indenture, to provide for the issuance of Additional Notes in accordance
with the limitations set forth in the Indenture as of the date of the Indenture,
or to allow any Guarantor to execute a supplemental indenture to the Indenture
and/or a Subsidiary Guarantee with respect to the Notes.

         12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for
30 days in the payment when due of interest or Special Interest on the Notes;
(ii) default in payment when due of principal of or premium, if any, on the
Notes when the same becomes due and payable at maturity, upon redemption
(including in connection with an offer to purchase) or otherwise, (iii) failure
by the Company or any of its Restricted Subsidiaries to comply with Section
4.07, 4.09, 4.10 or 5.01 of the Indenture; (iv) failure by the

                                      A-4
<PAGE>

Company or any of its Restricted Subsidiaries for 60 days after notice to the
Company by the Trustee or the Holders of at least 25% in principal amount of
the Notes (including Additional Notes, if any) then outstanding voting as a
single class to comply with certain other agreements in the Indenture or the
Notes; (v) default under certain other agreements relating to Indebtedness of
the Company which default is caused by a failure to pay principal of, or
interest or premium, if any, on such Indebtedness prior to the expiration of
the grace period provided in such Indebtedness of the date of such default or
results in the acceleration of such Indebtedness prior to its express
maturity; (vi) certain final judgments for the payment of money that remain
undischarged for a period of 60 days; (vii) certain events of bankruptcy or
insolvency with respect to the Company or any of its Material Subsidiaries;
and (viii) except as permitted by the Indenture, any Subsidiary Guarantee
shall be held in any judicial proceeding to be unenforceable or invalid or
shall cease for any reason to be in full force and effect or any Guarantor or
any Person acting on its behalf shall deny or disaffirm its obligations under
such Guarantor's Subsidiary Guarantee. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising
from certain events of bankruptcy or insolvency, all outstanding Notes will
become due and payable without further action or notice. Holders may not
enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of
the then outstanding Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders of the Notes notice of
any continuing Default or Event of Default (except a Default or Event of
Default relating to the payment of principal or interest) if it determines
that withholding notice is in their interest. The Holders of a majority in
aggregate principal amount of the Notes then outstanding by notice to the
Trustee may on behalf of the Holders of all of the Notes waive any existing
Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest on, or the
principal of, the Notes. The Company is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Company
is required upon becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of
Default.

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

         14. NO RECOURSE AGAINST OTHERS. A director, officer, employee,
incorporator or stockholder, of the Company, as such, shall not have any
liability for any obligations 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 Holder by accepting a Note waives and releases all
such liability. The waiver and release are part of the consideration for the
issuance of the Notes.

         15. AUTHENTICATION. This Note shall not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

         16. ABBREVIATIONS. Customary abbreviations may be used in the name

the issuance of an aggregate principal amount of $150,000,000 of 9.00% Senior
Subordinated Notes due 2011 (the "NOTES");

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

         WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

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

         1.       CAPITALIZED TERMS. Capitalized terms used herein without

         and delivered by the Trustee and to the Trustee and its successors and
         assigns, the Notes or the obligations of the Company hereunder or
         thereunder, that:

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

                 jointly and severally obligated to pay the same immediately.

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

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

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

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

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

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

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

                  (i) Pursuant to Section 10.03 of the Indenture, after giving
         effect to any maximum amount and any other contingent and fixed
         liabilities that are relevant under any applicable Bankruptcy or
         fraudulent conveyance laws, and after giving effect to any collections
         from, rights to receive contribution from or payments made by or on
         behalf of any other Guarantor in respect of the obligations of such
         other Guarantor under Article 10 of the Indenture, this new Subsidiary
         Guarantee shall be limited to the maximum amount permissible such that
         the obligations of such Guarantor under this Subsidiary Guarantee will
         not constitute a fraudulent transfer or conveyance.

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

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

                (a)   The Guaranteeing Subsidiary may not consolidate with or
         merge with or into (whether or not such Guarantor is the surviving
         Person) another corporation, Person or entity whether or not affiliated
         with such Guarantor unless:

                      (i)    subject to Sections 10.05 and 10.06 of the
                 Indenture, the Person formed by or surviving any such
                 consolidation or merger (if other than a Guarantor or the
                 Company) unconditionally assumes all the obligations of such
                 Guarantor, pursuant to a supplemental indenture in form and
                 substance reasonably satisfactory to the Trustee, under the
                 Notes, the Indenture and the Subsidiary Guarantee on the terms
                 set forth herein or therein; and

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

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

                (c)   Except as set forth in Articles 4 and 5 and Section 10.06
         of Article 10 of the Indenture, and notwithstanding clauses (a) and (b)
         above, nothing contained in the Indenture or in any of the Notes shall
         prevent any consolidation or merger of a Guarantor with or into the
         Company or another Guarantor, or shall prevent any sale or conveyance
         of the property of a Guarantor as an entirety or substantially as an
         entirety to the Company or another Guarantor.

         5.     RELEASES.

                (a)   In the event of a sale or other disposition of all of the
         assets of any Guarantor, by way of merger, consolidation or otherwise,
         or a sale or other disposition of all to the capital stock of any
         Guarantor, in each case to a Person that is not (either before or after
         giving effect to such transaction) a Restricted Subsidiary of the
         Company, then such Guarantor (in the event of a sale or other
         disposition, by way of merger, consolidation or otherwise, of all of
         the capital stock of such Guarantor) or the corporation acquiring the
         property (in the event of a sale or other disposition of all or
         substantially all of the assets of such Guarantor) will be released and
         relieved of any obligations under its Subsidiary Guarantee; PROVIDED
         that the Net Proceeds of such sale or other disposition are applied in
         accordance with the applicable provisions of the Indenture, including
         without limitation Section 4.10 of the Indenture. Upon delivery by the
         Company to the Trustee of an Officers' Certificate and an Opinion of
         Counsel to the effect that such sale or other disposition was made by
         the Company in accordance with the provisions of the Indenture,
         including without limitation Section 4.10 of the Indenture, the Trustee
         shall execute any

                                       H-3

<PAGE>
                                                                       EXHIBIT H

         documents reasonably required in order to evidence the release of any
         Guarantor from its obligations under its Subsidiary Guarantee.

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

         6.     NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Subsidiary Guarantees, the
Indenture or this Supplemental Indenture or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of the
Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws and it
is the view of the Commission that such a waiver is against public policy.

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

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

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

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

          2.       REGISTRATION UNDER THE SECURITIES ACT.

       (a)  Except as set forth in Section 2(b) below, the Company agrees to
     file under the Securities Act, as soon as practicable, but no later than
     60 days after the Closing Date, a registration statement relating to an
     offer to exchange (such registration statement, the "Exchange
     Registration Statement", and such offer, the "Exchange Offer") any and
     all of the Securities for a like aggregate principal amount of debt
     securities issued by the Company and guaranteed by each of the
     Guarantors, which debt securities and guarantees are substantially
     identical to the Securities and the related Guarantees, respectively
     (and are entitled to the benefits of a trust indenture which is
     substantially identical to the Indenture or is the Indenture and which
     has been qualified under the Trust Indenture Act), except that they have
     been registered pursuant to an effective registration statement under
     the Securities Act and do not contain provisions for the additional
     interest contemplated in Section 2(d) below (such new debt securities
     hereinafter called "Exchange Securities"). The Company agrees to use its
     best efforts to cause the Exchange Registration Statement to become
     effective under the Securities Act as soon as practicable, but no later
     than 180 days after the Closing Date. The Exchange Offer will be
     registered under the Securities Act on the appropriate form and will
     comply with all applicable tender offer rules and regulations under the
     Exchange Act. The Company further agrees to use its best efforts to
     commence and complete the Exchange Offer promptly, but no later than 45
     days after such registration statement has become effective, hold the
     Exchange Offer open for at least 30 days and exchange Exchange
     Securities for all Registrable Securities that have been properly
     tendered and not withdrawn on or prior to the expiration of the Exchange
     Offer. The Exchange Offer will be deemed to have been "completed" only
     if the debt securities and related guarantees received by holders other
     than Restricted Holders in the Exchange Offer for Registrable Securities
     are, upon receipt, transferable by each such holder without restriction
     under the Securities Act and the Exchange Act and without material
     restrictions under the blue sky or securities laws of a substantial
     majority of the States of the United States of America. The Exchange
     Offer shall be deemed to have been completed upon the earlier to occur
     of (i) the Company having exchanged the Exchange Securities for all
     outstanding Registrable Securities pursuant to the Exchange Offer and
     (ii) the Company having exchanged, pursuant to the Exchange Offer,
     Exchange Securities for all Registrable Securities that have been
     properly tendered and not withdrawn before the expiration of the
     Exchange Offer, which shall be on a date that is at least 30 days
     following the commencement of the Exchange Offer. The Company agrees (x)
     to include in the Exchange Registration Statement a prospectus for use
     in any resales by any holder of Exchange Securities that is a
     broker-dealer and (y) to keep such Exchange Registration Statement

                                       4

<PAGE>

     effective for a period (the "Resale Period") beginning when Exchange
     Securities are first issued in the Exchange Offer and ending upon the
     earlier of the expiration of the 180th day after the Exchange Offer has
     been completed or such time as such broker-dealers no longer own any
     Registrable Securities. With respect to such Exchange Registration
     Statement, such holders shall have the benefit of the rights of
     indemnification and contribution set forth in Sections 6(a), (c), (d)
     and (e) hereof.

        (b)  If (i) on or prior to the time the Exchange Offer is completed
     existing Commission interpretations are changed such that the debt
     securities or the related guarantees received by holders other than
     Restricted Holders in the Exchange Offer for Registrable Securities are
     not or would not be, upon receipt, transferable by each such holder
     without restriction under the Securities Act, (ii) the Exchange Offer
     has not been completed within 180 days following the Closing Date or
     (iii) the Exchange Offer is not available to any holder of the
     Securities, the Company shall, in lieu of (or, in the case of clause
     (iii), in addition to) conducting the Exchange Offer contemplated by
     Section 2(a), file under the Securities Act as soon as practicable, but
     no later than the later of 30 days after the time such obligation to
     file arises, a "shelf" registration statement providing for the
     registration of, and the sale on a continuous or delayed basis by the
     holders of, all of the Registrable Securities, pursuant to Rule 415 or
     any similar rule that may be adopted by the Commission (such filing, the
     "Shelf Registration" and such registration statement, the "Shelf
     Registration Statement"). The Company agrees to use its best efforts (x)
     to cause the Shelf Registration Statement to become or be declared
     effective no later than 180 days after such Shelf Registration Statement
     is filed and to keep such Shelf Registration Statement continuously
     effective for a period ending on the earlier of the second anniversary
     of the Effective Time or such time as there are no longer any
     Registrable Securities outstanding, PROVIDED, HOWEVER, that no holder
     shall be entitled to be named as a selling securityholder in the Shelf
     Registration Statement or to use the prospectus forming a part thereof
     for resales of Registrable Securities unless such holder is an Electing
     Holder, and (y) after the Effective Time of the Shelf Registration
     Statement, promptly upon the request of any holder of Registrable
     Securities that is not then an Electing Holder, to take any action
     reasonably necessary to enable such holder to use the prospectus forming
     a part thereof for resales of Registrable Securities, including, without
     limitation, any action necessary to identify such holder as a selling
     securityholder in the Shelf Registration Statement, PROVIDED, HOWEVER,
     that nothing in this Clause (y) shall relieve any such holder of the
     obligation to return a completed and signed Notice and Questionnaire to
     the Company in accordance with Section 3(d)(iii) hereof. The Company
     further agrees to supplement or make amendments to the Shelf
     Registration Statement, as and when required by the rules, regulations
     or instructions applicable to the registration form used by the Company
     for such Shelf Registration Statement or by the Securities Act or rules
     and regulations thereunder for shelf registration, and the Company
     agrees to furnish to each Electing Holder copies of any such supplement
     or amendment prior to its being used or promptly following its filing
     with the Commission.

        (c)  The Company may suspend the use of the prospectus for a period not
     to exceed 30 days in any 90-day period or an aggregate of 90 days in any
     12-month period if the Board of Directors of the Company shall have
     determined in good faith that because of valid business reasons (not
     including avoidance of the Company's obligations hereunder), including
     the acquisition or divestiture of assets, pending corporate developments
     and similar events, it is in the best interests of the Company to
     suspend such use, and prior to suspending such use the Company provides
     the holders with written notice of such suspension, which notice need
     not specify the nature of the event giving rise to such suspension.

                                       5

        (d)  In the event that (i) the Company has not filed the Exchange
     Registration Statement or Shelf Registration Statement on or before the
     date on which such registration statement is required to be filed
     pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange
     Registration Statement or Shelf Registration Statement has not become
     effective or been declared effective by the Commission on or before the
     date on which such registration statement is required to become or be
     declared effective pursuant to Section 2(a) or 2(b), respectively, or
     (iii) the Exchange Offer has not been completed within 45 days after the
     initial effective date of the Exchange Registration Statement relating
     to the Exchange Offer (if the Exchange Offer is then required to be
     made) or (iv) any Exchange Registration Statement or Shelf Registration
     Statement required by Section 2(a) or 2(b) hereof is filed and declared
     effective but shall thereafter either be withdrawn by the Company or
     shall become subject to an effective stop order issued pursuant to
     Section 8(d) of the Securities Act suspending the effectiveness of such
     registration statement (except as specifically permitted herein) without
     being succeeded immediately by an additional registration statement
     filed and declared effective (each such event referred to in clauses (i)
     through (iv), a "Registration Default" and each period during which a
     Registration Default has occurred and is continuing, a "Registration
     Default Period"), then, as liquidated damages for such Registration
     Default, subject to the provisions of Section 9(b), special interest
     ("Special Interest"), in addition to the Base Interest, shall accrue in
     an amount equal to $.05 per week per $1,000 principal amount of notes
     held by such Holder for the first 90 days of the Registration Default
     Period, and in an amount increasing by an additional $.05 per week per
     $1,000 principal amount of notes with respect to each subsequent 90 days
     of the Registration Default Period until all Registration Defaults have
     been cured, up to a maximum amount of special interest for all
     Registration Defaults of $.50 per week per $1,000 principal amount of
     notes.

        (e)  The Company and the Guarantors shall take all actions necessary or
     advisable to be taken by it to ensure that the transactions contemplated
     herein are effected as so contemplated, including all actions necessary or
     desirable to register the Guarantees under the registration statement
     contemplated in Section 2(a) or 2(b) hereof, as applicable.

        (f)  Any reference herein to a registration statement as of any time
     shall be deemed to include any document incorporated, or deemed to be
     incorporated, therein by reference as of such time and any reference
     herein to any post-effective amendment to a registration statement as of
     any time shall be deemed to include any document incorporated, or deemed
     to be incorporated, therein by reference as of such time.

3.       REGISTRATION PROCEDURES.

         If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

        (a)  At or before the Effective Time of the Exchange Offer or the Shelf
     Registration, as the case may be, the Company shall qualify the Indenture
     under the Trust Indenture Act of 1939.

        (b)  In the event that such qualification would require the appointment
     of a new trustee under the Indenture, the Company shall appoint a new
     trustee thereunder pursuant to the applicable provisions of the Indenture.

                                       6

     registration of Exchange Securities as contemplated by Section 2(a) (the
     "Exchange Registration"), if applicable, the Company shall, as soon as
     practicable (or as otherwise specified):

              (i)     prepare and file with the Commission, as soon as
         practicable but no later than 60 days after the Closing Date, an
         Exchange Registration Statement on any form which may be utilized by
         the Company and which shall permit the Exchange Offer and resales of
         Exchange Securities by broker-dealers during the Resale Period to be
         effected as contemplated by Section 2(a), and use its best efforts
         to cause such Exchange Registration Statement to become effective as

          participate as a member of an underwriting syndicate or selling group
          or "assist in the distribution" (within the meaning of the Conduct
          Rules (the "Conduct Rules) of the National Association of Securities
          Dealers, Inc. ("NASD") or any successor thereto, as amended from time
          to time) thereof, whether as a holder of such Registrable Securities
          or as an underwriter, a placement or sales agent or a broker or
          dealer in respect thereof, or otherwise, assist such broker-dealer in
          complying with the requirements of such Conduct Rules, including by
          (A) if such Conduct Rules shall so require, engaging a "qualified
          independent underwriter" (as defined in such Conduct Rules) to
          participate in the preparation of the Shelf Registration Statement
          relating to such Registrable Securities, to exercise usual standards
          of due diligence in respect thereto and, if any portion of the
          offering contemplated by such Shelf Registration Statement is an
          underwritten offering or is made through a placement or sales agent,
          to recommend the yield of such Registrable Securities, (B)
          indemnifying any such qualified independent underwriter to the extent
          of the indemnification of underwriters provided in Section 6 hereof
          (or to such other customary extent as may be requested by such
          underwriter), and (C) providing such information to such

          earnings statement of the Company and its subsidiaries complying with
          Section 11(a) of the Securities Act (including, at the option of the
          Company, Rule 158 thereunder).

      (e)  In the event that the Company would be required, pursuant to
Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or
sales agent, if any, therefor and the managing underwriters, if any, thereof,
the Company shall without delay prepare and furnish

                                      14

<PAGE>

to each of the Electing Holders, to each placement or sales agent, if any,
and to each such underwriter, if any, a reasonable number of copies of a
prospectus supplemented or amended so that, as thereafter delivered to
purchasers of Registrable Securities, such prospectus shall conform in all
material respects to the applicable requirements of the Securities Act and
the Trust Indenture Act and the rules and regulations of the Commission
thereunder and shall not contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing. Each Electing Holder agrees that upon receipt of any notice from
the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder
shall forthwith discontinue the disposition of Registrable Securities
pursuant to the Shelf Registration Statement applicable to such Registrable
Securities until such Electing Holder shall have received copies of such
amended or supplemented prospectus, and if so directed by the Company, such
Electing Holder shall deliver to the Company (at the Company's expense) all
copies, other than permanent file copies, then in such Electing Holder's
possession of the prospectus covering such Registrable Securities at the time
of receipt of such notice.

      (f)  In the event of a Shelf Registration, in addition to the
information required to be provided by each Electing Holder in its Notice
Questionnaire, the Company may require such Electing Holder to furnish to the
Company such additional information regarding such Electing Holder and such
Electing Holder's intended method of distribution of Registrable Securities
as may be required in order to comply with the Securities Act. Each such
Electing Holder agrees to notify the Company as promptly as practicable of
any inaccuracy or change in information previously furnished by such Electing
Holder to the Company or of the occurrence of any event in either case as a
result of which any prospectus relating to such Shelf Registration contains
or would contain an untrue statement of a material fact regarding such
Electing Holder or such Electing Holder's intended method of disposition of
such Registrable Securities or omits to state any material fact regarding
such Electing Holder or such Electing Holder's intended method of disposition
of such Registrable Securities required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing, and promptly to furnish to the Company any additional information
required to correct and update any previously furnished information or
required so that such prospectus shall not contain, with respect to such
Electing Holder or the disposition of such Registrable Securities, an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing.

       (g)  Until the expiration of two years after the Closing Date, the
Company will not, and will use its best efforts not to permit any of its
"affiliates" (as defined in Rule 144) to, resell any of the Securities that
have been reacquired by any of them except pursuant to an effective
registration statement under the Securities Act.

after receipt of a request therefor. Notwithstanding the foregoing, the

fees and commissions and underwriting discounts and commissions attributable
to the sale of such Registrable Securities and the fees and disbursements of
any counsel or other advisors or experts retained by such holders (severally
or jointly), other than the counsel and experts specifically referred to

subsequent to the Effective Time when a prospectus would be required to be
delivered under the Securities Act, other than from (i) such time as a notice
has been given to holders of Registrable Securities pursuant to Section
3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii) such time as the
Company furnishes an amended or supplemented prospectus pursuant to Section
3(c)(iv) or Section 3(e) hereof, each such registration statement, and each

      (c)  The compliance by the Company with all of the provisions of this

       6.  INDEMNIFICATION.

      (a)  INDEMNIFICATION BY THE COMPANY AND EACH OF THE GUARANTORS. The
Company and each of the Guarantors, jointly and severally, will indemnify and
hold harmless each of the

                                      17

<PAGE>

holders of Registrable Securities included in an Exchange Registration
Statement, each of the Electing Holders of Registrable Securities included in
a Shelf Registration Statement and each person who participates as a
placement or sales agent or as an underwriter in any offering or sale of such
Registrable Securities against any losses, claims, damages or liabilities,
joint or several, to which such holder, agent or underwriter may become
subject under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Exchange Registration Statement or Shelf
Registration Statement, as the case may be, under which such Registrable
Securities were registered under the Securities Act, or any preliminary,
final or summary prospectus contained therein or furnished by the Company to
any such holder, Electing Holder, agent or underwriter, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse
such holder, such Electing Holder, such agent and such underwriter for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that none of the Company or the Guarantors shall
be liable to any such person in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement, or preliminary, final or summary prospectus, or
amendment or supplement thereto, in reliance upon and in conformity with
written information furnished to the Company by such person expressly for use
therein.

      (b)  INDEMNIFICATION BY THE HOLDERS AND ANY AGENTS AND UNDERWRITERS.
The Company may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Section 2(b)
hereof and to entering into any underwriting agreement with respect thereto,
that the Company shall have received an undertaking reasonably satisfactory
to it from the Electing Holder of such Registrable Securities and from each
underwriter named in any such underwriting agreement, severally and not
jointly, to (i) indemnify and hold harmless the Company, each of the
Guarantors, and all other holders of Registrable Securities, against any
losses, claims, damages or liabilities to which the Company, any of the
Guarantors or such other holders of Registrable Securities may become
subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon an untrue statement or alleged untrue statement of a
material fact contained in such registration statement, or any preliminary,
final or summary prospectus contained therein or furnished by the Company to
any such Electing Holder, agent or underwriter, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Electing
Holder or underwriter expressly for use therein, and (ii) reimburse the
Company and each of the Guarantors for any legal or other expenses reasonably
incurred by the Company and each of the Guarantors in connection with
investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that no such Electing Holder shall be required
to undertake liability to any person under this Section 6(b) for any amounts
in excess of the dollar amount of the proceeds to be received by such
Electing Holder from the sale of such Electing Holder's Registrable
Securities pursuant to such registration.

                                      18

<PAGE>

      (c)  NOTICES OF CLAIMS, ETC. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement
of any action, such indemnified party shall, if a claim in respect thereof is
to be made against an indemnifying party pursuant to the indemnification
provisions of or contemplated by this Section 6, notify such indemnifying
party in writing of the commencement of such action; but the omission so to
notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party otherwise than under the indemnification
provisions of or contemplated by Section 6(a) or 6(b) hereof. In case any
such action shall be brought against any indemnified party and it shall
notify an indemnifying party of the commencement thereof, such indemnifying
party shall be entitled to participate therein and, to the extent that it
shall wish, jointly with any other indemnifying party similarly notified, to
assume the defense thereof, with counsel selected by the indemnifying party
and reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof, such indemnifying
party shall not be liable to such indemnified party for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by
such indemnified party, in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party is
an actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the
indemnified party from all liability arising out of such action or claim and
(ii) does not include a statement as to or an admission of fault, culpability
or a failure to act by or on behalf of any indemnified party.

       (d)  CONTRIBUTION. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or
insufficient to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages
or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party and the
indemnified party in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative fault of such indemnifying party and indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state
a material fact relates to information supplied by such indemnifying party or
by such indemnified party, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The parties hereto agree that it would not be just and equitable if
contributions pursuant to this Section 6(d) were determined by pro rata
allocation (even if the holders or any agents or underwriters or all of them
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations
referred to in this Section 6(d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities
(or actions in respect thereof) referred to above shall be deemed to include
any legal or other fees or expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 6(d), no holder shall be
required to contribute any amount in excess of the amount by which the dollar
amount of the proceeds received by

                                      19

<PAGE>

such holder from the sale of any Registrable Securities (after deducting any
fees, discounts and commissions applicable thereto) exceeds the amount of any
damages which such holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission, and
no underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the Registrable Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The holders' and any underwriters' obligations
in this Section 6(d) to contribute shall be several in proportion to the
principal amount of Registrable Securities registered or underwritten, as the
case may be, by them and not joint.

      (e)  FURTHER LIABILITY. The obligations of the Company and each of the
Guarantors under this Section 6 shall be in addition to any liability which
the Company or any of the Guarantors may otherwise have and shall extend,
upon the same terms and conditions, to each officer, director and partner of
each holder, agent and underwriter and each person, if any, who controls any
holder, agent or underwriter within the meaning of the Securities Act; and
the obligations of the holders and any agents or underwriters contemplated by
this Section 6 shall be in addition to any liability which the respective
holder, agent or underwriter may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of the Company or any
of the Guarantors (including any person who, with his consent, is named in
any registration statement as about to become a director of the Company or
any of the Guarantors) and to each person, if any, who controls the Company
within the meaning of the Securities Act.

      7.   UNDERWRITTEN OFFERINGS.

      (a)  SELECTION OF UNDERWRITERS. If any of the Registrable Securities
covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be
designated by Electing Holders holding at least a majority in aggregate
principal amount of the Registrable Securities to be included in such
offering, provided that such designated managing underwriter or underwriters
is or are reasonably acceptable to the Company.

      (b)  PARTICIPATION BY HOLDERS. As a condition to participating in the
underwritten offering, each holder of Registrable Securities shall agree with
each other such holder that no such holder may participate in such
underwritten offering unless such holder (i) agrees to sell such holder's
Registrable Securities on the basis provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and
(ii) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents reasonably required

the Commission thereunder, and shall take such further action as any holder
of Registrable Securities may reasonably request, all to the extent required
from time to time to enable such holder to sell Registrable Securities
without registration under the Securities Act within the limitations of the
exemption provided by Rule 144 under the Securities Act, as such Rule may be
amended from time to time, or any similar or successor rule or regulation
hereafter adopted by the Commission. Upon the request of any holder of
Registrable Securities in connection with that holder's sale pursuant to Rule
144, the Company shall deliver to such holder a written statement as to
whether it has complied with such requirements.

      9.   MISCELLANEOUS.

      (b)  SPECIFIC PERFORMANCE. The parties hereto acknowledge that there
would be no adequate remedy at law if the Company fails to perform any of its

failure, and accordingly agree that the Purchasers and such holders, in
addition to any other remedy to which they may be entitled at law or in
equity, shall be entitled to compel specific performance of the obligations
of the Company under this Exchange and Registration Rights Agreement in
accordance with the terms and conditions of this Exchange and Registration
Rights Agreement, in any court of the United States or any State thereof
having jurisdiction.

forth in the security register or other records of the Company, or to such
other address as the Company or any such holder may have furnished to the
other in writing in accordance herewith, except that notices of change of
address shall be effective only upon receipt.

      (d)  PARTIES IN INTEREST. All the terms and provisions of this Exchange
and Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders
from time to time of the Registrable Securities and the respective successors
and assigns of the parties hereto and such holders. In the event that any
transferee of any holder of Registrable Securities shall acquire Registrable
Securities, in any manner, whether by gift, bequest, purchase, operation of
law or otherwise, such transferee shall, without any further writing or
action of any kind, be deemed a beneficiary hereof for all purposes and such
Registrable Securities shall be held subject to all of the terms of this
Exchange and Registration Rights Agreement, and by taking and holding such
Registrable Securities such transferee shall be entitled to receive the
benefits of, and be conclusively deemed to have agreed to be bound by all of
