     Section 2.2 hereof, the Trustee shall authenticate one or more Unrestricted
     Global Notes in an aggregate principal amount equal to the principal amount
     of Definitive Notes so transferred.

           (i) General Provisions Relating to Transfers and Exchanges.
               ------------------------------------------------------

               (1) To permit registrations of transfers and exchanges, the
     Company shall execute and the Trustee shall authenticate Global Notes and
     Definitive Notes upon receipt of an Authentication Order.

               (2) 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 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, 3.7, 4.14 and 10.1 hereof).

               (3) 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.

               (4) 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
     Indebtedness, and entitled to the same benefits under this Indenture, as
     the Global Notes or Definitive Notes surrendered upon such registration of
     transfer or exchange.

               (5) The Company and the Registrar 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 3.3 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.

               (6) 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.

               (7) The Trustee shall authenticate Global Notes and Definitive
     Notes in accordance with the provisions of Section 2.2 hereof.

               (8) All certifications, certificates and Opinions of Counsel
     required to be submitted to the Registrar pursuant to this Section 2.6 to
     effect a registration of transfer or exchange may be submitted by
     facsimile.

                                       44
<PAGE>

          Notwithstanding anything herein to the contrary, as to any
certifications and certificates delivered to the Registrar pursuant to this
Section 2.6, the Registrar's duties shall be limited to confirming that any such
certifications and certificates delivered to it are in the form of Exhibits B, C
and D attached hereto. The Registrar shall not be responsible for confirming the
truth or accuracy of representations made in any such certifications or
certificates.

SECTION 2.7.   REPLACEMENT NOTES

          If any mutilated Note is surrendered to the Trustee or the Company and
the Trustee and the Company receive evidence (which evidence may be from the
Trustee) to their satisfaction of the destruction, loss or theft of any Note and
if the requirements of Section 8-405 of the New York Uniform Commercial Code are
met, 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.

SECTION 2.8.   OUTSTANDING NOTES

          The Notes outstanding at any time are all the Notes authenticated by
the Trustee (including any Note represented by a Global Note) except for those
cancelled by it or at its direction, 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 2.9 hereof, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note. If a Note is replaced pursuant to Section 2.7 hereof, such Note,
together with the Guarantee of that particular Note endorsed thereon, 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 4.1 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 the 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 2.9.   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.

                                       45
<PAGE>

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 Definitive 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, or at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Company or an Affiliate of the Company), and no one else shall
cancel all Notes surrendered for registration of transfer, exchange, payment,
replacement or cancellation and shall destroy cancelled Notes (subject to the
record retention requirement of the Exchange Act). Certification of the
destruction of all cancelled 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.

SECTION 2.12.  DEFAULTED INTEREST

          Any interest on any Note which is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date plus, to the extent lawful,
any interest payable on the defaulted interest at the rate and in the manner
provided in Section 4.1 hereof and in the Note (herein called "Defaulted
Interest") shall forthwith cease to be payable to the registered holder on the
relevant Record Date, and such Defaulted Interest may be paid by the Company, at
its election in each case, as provided in clause (1) or (2) below:

               (1) The Company may elect to make payment of any Defaulted
     Interest to the Persons in whose names the Notes are registered at the
     close of business on a Special Record Date for the payment of such
     Defaulted Interest, which shall be fixed in the following manner. The
     Company shall notify the Trustee and the Paying Agent in writing of the
     amount of Defaulted Interest proposed to be paid on each Note and the date
     of the proposed payment, and at the same time the Company shall deposit
     with the Paying Agent an amount of cash equal to the aggregate amount
     proposed to be paid in respect of such Defaulted Interest or shall make
     arrangements reasonably satisfactory to the Paying Agent for such deposit
     prior to the date of the proposed payment, such cash when deposited to be
     held in trust for the benefit of the Persons entitled to such Defaulted
     Interest as provided in this clause (1). Thereupon the Paying Agent shall
     fix a "Special Record Date" for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to the
     date of the proposed payment and not less than 10 days after the receipt by
     the

                                       46
<PAGE>

     Paying Agent of the notice of the proposed payment. The Paying Agent shall
     promptly notify the Company and the Trustee of such Special Record Date
     and, in the name and at the expense of the Company, shall cause notice of
     the proposed payment of such Defaulted Interest and the Special Record Date
     therefor to be mailed, first-class postage prepaid, to each Holder at its
     address as it appears in the Note register maintained by the Registrar not
     less than 10 days prior to such Special Record Date. Notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor
     having been mailed as aforesaid, such Defaulted Interest shall be paid to
     the persons in whose names the Notes (or their respective predecessor
     Notes) are registered on such Special Record Date and shall no longer be
     payable pursuant to the following clause (2).

               (2) The Company may make payment of any Defaulted Interest in any
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Notes may be listed, and upon such notice
     as may be required by such exchange, if, after notice given by the Company
     to the Trustee and the Paying Agent of the proposed payment pursuant to
     this clause, such manner shall be deemed practicable by the Trustee and the
     Paying Agent.

               Subject to the foregoing provisions of this Section, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Note.

SECTION 2.13.  CUSIP NUMBERS

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

                                   ARTICLE III

                                   REDEMPTION

at any time on or prior to April 15, 2004, upon any Public Equity Offering, up
to 35% of the aggregate principal amount of the Notes issued pursuant to this
Indenture may be redeemed at the option of the Company within 90 days of such
Public Equity Offering, on not less than 30 days, but not more than 60 days,
prior notice to each Holder of the Notes to be redeemed, with cash from the Net
Cash Proceeds of such Public Equity Offering, at a redemption price equal to
109.25% of the principal amount thereof (subject to the right of Holders of
record on a Record Date to receive the corresponding interest (and the
corresponding Liquidated Damages, if any) due on the Interest Payment Date that
is on or prior to such Redemption Date) together with accrued and unpaid
interest and Liquidated Damages, if any, thereon to the Redemption Date;
provided that immediately following such redemption not less than 65% of the
aggregate principal amount of the Notes originally issued pursuant to this
Indenture remain outstanding.

          (c) Any redemption pursuant to this Section 3.1 shall be made pursuant
to the provisions of Sections 3.2 through 3.7 hereof.

SECTION 3.2.  NOTICES TO TRUSTEE

          If the Company elects to redeem Notes pursuant to Section 5 of the
Notes, it shall notify the Trustee and the Paying Agent in writing of the
Redemption Date and the principal amount of Notes to be redeemed and whether it
wants the Paying Agent to give notice of redemption to the Holders.

          If the Company elects to reduce the principal amount of Notes to be
redeemed pursuant to Section 5 of the Notes by crediting against any such
redemption Notes it has not previously delivered to the Trustee and the Paying
Agent for cancellation, it shall so notify the Trustee, in the form of an
Officers' Certificate, and the Paying Agent of the amount of the reduction and
deliver such Notes with such notice.

                                       48
<PAGE>

          The Company shall give each notice to the Trustee and the Paying Agent
provided for in this Section 3.2 at least 45, but not more than 75, days before
the Redemption Date (unless a shorter notice shall be satisfactory to the
Trustee and the Paying Agent). Any such notice may be cancelled at any time
prior to notice of such redemption being mailed to any Holder and shall thereby
be void and of no effect.

SECTION 3.3.   SELECTION OF NOTES TO BE REDEEMED

          If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes or portions thereof to be redeemed among the
Holders of the Notes in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed or, if the
Notes are not so listed, on a pro rata basis, by lot or in accordance with any
other method the Trustee considers fair and appropriate.

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

SECTION 3.4.   NOTICE OF REDEMPTION

          At least 30 days, but not more than 60 days prior to the Redemption
Date, the Company shall mail a notice of redemption by first class mail, postage
prepaid, to the Trustee, the Paying Agent and each Holder whose Notes are to be
redeemed. At the Company's request, the Paying Agent shall give the notice of
redemption in the Company's name and at the Company's expense. Each notice for
redemption shall identify the Notes to be redeemed and shall state:

               (1) the Redemption Date;

               (2) the Redemption Price, including accrued and unpaid interest
     and Liquidated Damages, if any, to be paid upon such redemption;

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

               (4) that Notes called for redemption must be surrendered to the

               (5) that, unless (a) the Company defaults in its obligation to
     deposit with the Paying Agent cash which through the scheduled payment of
     principal and interest (and Liquidated Damages, if any) in respect thereof
     in accordance with their terms shall provide

                                       49
<PAGE>

     the amount to fund the Redemption Price in accordance with Section 3.6
     hereof or (b) such redemption payment is prohibited, interest (and
     Liquidated Damages, if any) on Notes called for redemption ceases to accrue
     on and after the Redemption Date and the only remaining right of the
     Holders of such Notes is to receive payment of the Redemption Price,
     including accrued and unpaid interest (and Liquidated Damages, if any) to
     the Redemption Date, upon surrender to the Paying Agent of the Notes called
     for redemption and to be redeemed;

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

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

               (8) the CUSIP number of the Notes to be redeemed; and

               (9) that the notice is being sent pursuant to this Section 3.4
     and pursuant to the optional redemption provisions of Section 5 of the
     Notes.

SECTION 3.5.   EFFECT OF NOTICE OF REDEMPTION

          Once notice of redemption is mailed in accordance with Section 3.4
hereof, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price, including accrued and unpaid interest (and
Liquidated Damages, if any) to the Redemption Date. Upon surrender to the
Trustee or Paying Agent, such Notes called for redemption shall be paid at the
Redemption Price, including interest and Liquidated Damages, if any, accrued and
unpaid to the Redemption Date; provided, that if the Redemption Date is on or
after an interest Record Date on which the Holders of record have a right to
receive the corresponding interest due, and Liquidated Damages, if any, and on
or before the associated Interest Payment Date, any accrued and unpaid interest
and Liquidated Damages, if any, due on such Interest Payment Date shall be paid
to the Person in whose name a Note is registered at the close of business on
such Record Date on the corresponding Interest Payment Date; and provided,
further, that if a Redemption Date is a Legal Holiday, payment shall be made on
the next succeeding Business Day and no interest (or Liquidated Damages, if any)
shall accrue for the period from such Redemption Date to such succeeding
Business Day.

SECTION 3.6.   DEPOSIT OF REDEMPTION PRICE

          Prior to 10:00 a.m. New York City time on the Redemption Date, the
Company shall deposit with the Paying Agent (which may not for purposes of this
Section 3.6, notwithstanding anything in this Indenture to the contrary, be the
Company or any Affiliate of the Company) cash

                                       50
<PAGE>

sufficient to pay the Redemption Price of all Notes to be redeemed on such
Redemption Date (other than Notes or portions thereof called for redemption on
that date that have been delivered by the Company to the Trustee for
cancellation). The Paying Agent shall promptly return to the Company any cash so
deposited (together with all money earned on funds so held in trust, if
applicable) which is not required for that purpose upon the written request of
the Company.

          If the Company complies with the preceding paragraph and payment of
the Notes called for redemption is not prohibited for any reason, interest (and
Liquidated Damages, if any) on the Notes to be redeemed shall cease to accrue on
the applicable Redemption Date, whether or not such Notes are presented for
payment. Notwithstanding anything herein to the contrary, if any Note
surrendered for redemption in the manner provided in the Notes shall not be so
paid upon surrender for redemption because of the failure of the Company to
comply with the preceding paragraph, interest (and Liquidated Damages, if any)
shall continue to accrue and be paid from the Redemption Date until such payment
is made on the unpaid principal, and, to the extent lawful, on any interest not
paid on such unpaid principal, in each case at the rate and in the manner
provided in Section 4.1 hereof and the Note.

SECTION 3.7.  NOTES REDEEMED IN PART

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

SECTION 3.8.  NO MANDATORY REDEMPTION

          The Company shall not be required to make mandatory redemption
payments with respect to the Notes. The Notes shall not have the benefit of any
sinking fund.

SECTION 4.1.  PAYMENT OF NOTES

          The Company shall pay the principal of and interest (and Liquidated
Damages, if any) on the Notes on the dates and in the manner provided herein and
in the Notes. An installment of principal of or interest (or Liquidated Damages,
if any) on the Notes shall be considered paid on the date it is due if the
Trustee or Paying Agent (other than the Company or an Affiliate of the Company)
holds for the benefit of the Holders (on or before 10:00 a.m. New York City time
to the extent necessary to provide the funds to the Depositary in accordance
with the Depositary's procedures) on that date cash deposited and designated for
and sufficient to pay the installment.

                                       51

presented or surrendered for payment, where Notes may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company and the Guarantors in respect of the Notes and this Indenture may be
served. The Company and the Guarantors shall give prompt written notice to the
Trustee and the Paying Agent of the location, and any change in the location, of
such office or agency. If at any time the Company and the Guarantors shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee and the Paying Agent with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 13.2 hereof.

          The Company and the Guarantors may also from time to time designate
one or more other offices or agencies where the Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company and the Guarantors of their obligation to
maintain an office or agency in the Borough of Manhattan, The City of New York,
for such purposes. The Company and the Guarantors shall give prompt written
notice to the Trustee and the Paying Agent of any such designation or rescission
and of any change in the location of any such other office or agency. The
Company hereby initially designates the Corporate Trust Office of the Trustee as
such office.

SECTION 4.3.  LIMITATION ON RESTRICTED PAYMENTS

          The Company and the Guarantors shall not, and neither the Company nor
the Guarantors shall permit any of their respective Subsidiaries to, directly or
indirectly, make any Restricted Payment if, after giving effect to such
Restricted Payment on a pro forma basis:

     Company and its Subsidiaries, including after giving effect to such
     proposed Restricted Payment, on and after the Issue Date, would exceed,
     without duplication, the sum of:

                    (a) $25,000,000, plus

for the period (taken as one accounting period), commencing on the first day of
the fiscal quarter including the Issue Date, to and including the last day of
the fiscal quarter ended immediately prior to the date of each such calculation
for which the Company's consolidated financial statements are required to be

Consolidated Net Income for such period is a deficit, then minus 100% of such
deficit), plus

                    (c) the aggregate Net Cash Proceeds received by the Company

Qualified Exchange or a Permitted Investment pursuant to clause (f) thereof or,
to avoid duplication, otherwise given credit for in any provision of the
following paragraph), after the Issue Date, plus

                    (d) except in each case, in order to avoid duplication, to
the extent any such payment or proceeds have been included in the calculation of
Consolidated Net Income, an amount equal to the net reduction in Investments
(other than returns of or from Permitted Investments) in any Person resulting
from distributions on or repayments of any Investments, including payments of
interest on Indebtedness, dividends, repayments of loans or advances, or other

"Investments"), not to exceed, in each case, the amount of Investments
previously made by the Company or any Subsidiary in such Person, including, if
applicable, such Unrestricted Subsidiary, less the cost of disposition.

          The foregoing clauses (2) and (3) of the immediately preceding
paragraph, however, shall not prohibit:

                    (v) Restricted Payments in an amount not to exceed
$25,000,000 in the aggregate (exclusive of any accrued and unpaid interest
payable in connection with repurchases of Subordinated Indebtedness) consisting

Subordinated Indebtedness on and after the Issue Date,

                    (w) in addition to the amounts permitted under clause (v)

foregoing clauses (x) and (z) (but not pursuant to clause (v) or (w) or (y)) of
the immediately preceding sentence, however, will be counted as Restricted
Payments made for purposes of the calculation of the aggregate amount of
Restricted Payments available to be made referred to in clause (3) of the first
paragraph under this Section 4.3.

          For purposes of this Section 4.3, the amount of any Restricted Payment
made or returned, if other than in cash, shall be the fair market value thereof,

Payments made during the preceding 12-month period and not previously reported
pursuant to clause (a) of this paragraph, the Company shall deliver an Officers'
Certificate to the Trustee describing in reasonable detail the nature of such
Restricted Payment, stating that the Restricted Payment is permitted and setting
forth the basis upon with the calculations required by this covenant were
computed.

          Except as otherwise permitted by Article V, Section 4.14 or Section

Company nor any Guarantor shall be required to preserve, with respect to

the business of the Company and (b) the loss thereof would not have a material
adverse effect on the Company's or any Guarantor's ability to perform its

their Subsidiaries to be maintained and kept in good condition, repair and
working order (reasonable wear and tear excepted) so that the business carried
on in connection therewith may be properly conducted at all times; provided,
however, that nothing in this Section 4.6 shall prevent the Company or any
Guarantor from discontinuing any operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposal is
(a)(i) in the judgment of the Board of Directors of the Company, desirable in
the conduct of the business of the Company and (ii) would not have a material
adverse effect on the Company's or any Guarantor's ability to perform its
obligations under this Indenture or the Notes or (b) otherwise permitted under
Section 4.14.

the Company and adequate and appropriate for the conduct of the business of the
Company, the Guarantors and such Subsidiaries in a prudent manner for entities
similarly situated in the industry in which, at any time of determination, they
are then operating.

Officers' Certificate shall also notify the Trustee should the relevant fiscal
year end on any date other than the current fiscal year end date.

          (b)  The Company shall, so long as any of the Notes are outstanding,
deliver to the Trustee, promptly upon becoming aware of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with respect thereto.
The Trustee shall not be deemed to have knowledge of any Default, any Event of
Default or any such fact unless one of its Trust Officers receives written
notice thereof from the Company or any of the Holders.

SECTION 4.8. REPORTS

          Whether or not the Company is subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, the Company shall furnish to the
Trustee, to each Holder and to prospective purchasers of Notes identified to the
Company by an Initial Purchaser, within 5 days after the Company is or would
have been (if it were subject to such reporting obligations) required to file
such with the SEC, annual and quarterly financial statements substantially
equivalent to financial statements that would have been included in reports
filed with the SEC, if the Company were subject to the requirements of Section
13 or 15(d) of the Exchange Act, including, with respect to annual information
only, a report thereon by the Company's certified independent public accountants
as such would be required in such reports to the SEC, and, in each case,
together with a management's discussion and analysis of financial condition and
results of operations which would be so required and, unless the SEC will not
accept such reports, file with the SEC the annual, quarterly and other reports
which the Company is or (if it were subject to such reporting requirements)
would have been required to file with the SEC.

          For so long as any Transfer Restricted Notes remain outstanding, the
Company shall make available (which shall include filings by EDGAR) to all
Holders and to securities analysts and prospective investors, upon their
reasonable request, the information required to be delivered pursuant to Rule
144A(d)(4) under the Securities Act.

SECTION 4.9. LIMITATION ON STATUS AS INVESTMENT COMPANY

          Neither the Company nor any of its Subsidiaries shall become required
to register as an "investment company" (as that term is defined in the
Investment Company Act of 1940, as amended).

                                       56

SECTION 4.10. LIMITATION ON TRANSACTIONS WITH AFFILIATES

          Neither the Company nor any of its Subsidiaries shall, on or after the
Issue Date, enter into or suffer to exist any contract, agreement, arrangement
or transaction with any Affiliate (an "Affiliate Transaction"), or any series of
related Affiliate Transactions, (other than Exempted Affiliate Transactions),
(1) unless it is determined that the terms of such Affiliate Transaction are
fair and reasonable to the Company, and no less favorable to the Company than
could have been obtained in an arm's length transaction with a non-Affiliate,
and (2) if involving consideration to either party in excess of $5,000,000,
unless such Affiliate Transaction(s) is evidenced by an Officers' Certificate
addressed and delivered to the Trustee certifying that such Affiliate
Transaction(s) has been approved by a majority of the members of the Company's
Board of Directors that are disinterested in such transaction, if there are any
directors who are so disinterested, and (3) if involving consideration to either
party in excess of $10,000,000, unless in addition the Company, prior to the
consummation thereof, obtains a written favorable opinion as to the fairness of
such transaction to the Company from a financial point of view from an
independent investment banking firm of national reputation in the United States
or, if pertaining to a matter for which such investment banking firms do not
customarily render such opinions, an accounting, appraisal or valuation firm of
national reputation in the United States.

SECTION 4.11.  LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS

          Except as set forth in this Section 4.11, the Company and the
Guarantors shall not, and neither the Company nor the Guarantors shall permit
any of their respective Subsidiaries to, directly or indirectly, issue, assume,
guarantee, incur, become directly or indirectly liable with respect to
(including as a result of an Acquisition), or otherwise become responsible for,
contingently or otherwise (individually and collectively, to "incur" or, as
appropriate, an "incurrence"), any Indebtedness (including Disqualified Capital
Stock and Acquired Indebtedness), other than Permitted Indebtedness.

          Notwithstanding the foregoing if:

               (1)  no Default or Event of Default shall have occurred and be
     continuing at the time of, or would occur after giving effect on a pro
     forma basis to, such incurrence of Indebtedness and

               (2)  on the date of such incurrence (the "Incurrence Date"), the
     Company's Consolidated Coverage Ratio for the Reference Period immediately
     preceding the Incurrence Date, after giving effect on a pro forma basis to
     such incurrence of such Indebtedness and, to the extent set forth in the
     definition of Consolidated Coverage Ratio, the use of proceeds thereof,
     would be at least 2.5 to 1.0 (the "Debt Incurrence Ratio"),

then the Company and the Guarantors may incur such Indebtedness (including
Disqualified Capital Stock).

                                       57
<PAGE>

          In addition, the foregoing limitations of the first paragraph of this
Section 4.11 will not prohibit:

          (a)  the Company's incurrence or the incurrence by any Guarantor or
Non-Guarantor Subsidiary of Capital Expenditure Indebtedness; provided, that

               (1)  the aggregate amount of such Indebtedness incurred and
     outstanding at any time pursuant to this paragraph (a) (plus any
     Refinancing Indebtedness issued to retire, defease, refinance, replace or
     refund such Indebtedness) shall not exceed $25,000,000, and

               (2)  in each case, such Indebtedness shall not constitute more
     than 100% of the Company's cost or the cost to such Guarantor or
     Non-Guarantor Subsidiary (determined in accordance with GAAP), as
     applicable, of the property so acquired, constructed, installed, improved
     or leased;

          (b)  if no Event of Default shall have occurred and be continuing, the
Company's incurrence or the incurrence by any Guarantor or Non-Guarantor
Subsidiary of Indebtedness in an aggregate amount incurred and outstanding at
any time pursuant to this paragraph (b) (plus any Refinancing Indebtedness
incurred to retire, defease, refinance, replace or refund such Indebtedness) of
up to $25,000,000; and

          (c)  the Company's incurrence or the incurrence by any Guarantor of
Indebtedness pursuant to the Credit Agreement in an aggregate amount incurred
and outstanding at any time pursuant to this paragraph (c) (plus any Refinancing
Indebtedness incurred to retire, defease, refinance, replace or refund such
Indebtedness) of up to $600,000,000, minus the amount of any such Indebtedness
(1) retired with the Net Cash Proceeds from any Asset Sale applied to
permanently reduce the outstanding amounts or the commitments with respect to
such Indebtedness pursuant to clause (1)(b)(ii) of Section 4.14 or (2) assumed
by a transferee in an Asset Sale so long as neither the Company nor such
Guarantor continues to be an obligor under such Indebtedness.

          Indebtedness (including Disqualified Capital Stock) of any Person
which is outstanding at the time such Person becomes one of the Company's
Subsidiaries (including upon designation of any subsidiary or other Person as a
Subsidiary) or is merged with or into or consolidated with the Company or one of
the Company's Subsidiaries shall be deemed to have been incurred at the time
such Person becomes or is designated one of the Company's Subsidiaries or is
merged with or into or consolidated with the Company or one of the Company's
Subsidiaries as applicable.

          Notwithstanding any other provision of this Section 4.11, but only to
avoid duplication, a guarantee of the Company's Indebtedness or of the
Indebtedness of a Guarantor or a Non-Guarantor Subsidiary incurred in accordance
with the terms of this Indenture issued at the time such Indebtedness was
incurred or if later at the time the guarantor thereof became one of the
Company's Subsidiaries will not constitute a separate incurrence, or amount
outstanding, of Indebtedness. Upon each incurrence the Company may determine
pursuant to which provision of

                                       58
<PAGE>

this Section 4.11 such Indebtedness is being incurred and the Company may
subdivide an amount of Indebtedness and determine more than one provision
pursuant to which such amount of Indebtedness is being incurred and such
Indebtedness shall not be deemed to have been incurred or outstanding under any
other provision of this Section 4.11, except as stated otherwise in the
foregoing provisions.

SECTION 4.12.  LIMITATIONS ON DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING
               SUBSIDIARIES

          The Company and the Guarantors shall not, and neither the Company nor
the Guarantors shall permit any of their respective Subsidiaries to, directly or
indirectly, create, assume or suffer to exist any consensual restriction on the
ability of any of the Subsidiary of the Company (w) to pay dividends or make
other distributions to or on behalf of, or (x) to pay any obligation to or on
behalf of, or (y) otherwise to transfer assets or property to or on behalf of,
or (z) to make or pay loans or advances to or on behalf of, the Company or any
of its Subsidiaries except:

               (1)  restrictions imposed by the Notes or this Indenture or by
     the Company's other Indebtedness (which may also be guaranteed by the
     Guarantors) ranking senior to the Notes or the Guarantees, as applicable;
     provided, that such restrictions are no more restrictive than those imposed
     by this Indenture and the Notes.

               (2)  restrictions imposed by applicable law,

               (3)  existing restrictions under Existing Indebtedness,

               (4)  restrictions under any Acquired Indebtedness not incurred in
     violation of this Indenture or any agreement (including any Equity
     Interest) relating to any property, asset, or business acquired by the
     Company or any of its Subsidiaries, which restrictions in each case existed
     at the time of acquisition, were not put in place in connection with or in
     anticipation of such acquisition and are not applicable to any Person,
     other than the Person acquired, or to any property, asset or business,
     other than the property, assets and business so acquired,

               (5)  any restriction imposed by Indebtedness incurred under the
     Credit Agreement pursuant to clause (c) of Section 4.11; provided, that
     such restriction or requirement is no more restrictive than that imposed by
     the Credit Agreement as of the Issue Date,

               (6)  restrictions with respect solely to any of the Company's
     Subsidiaries imposed pursuant to a binding agreement which has been entered
     into for the sale or disposition of all or substantially all of the Equity
     Interests or assets of such Subsidiary; provided, that such restrictions
     apply solely to the Equity Interests or assets of such Subsidiary which are
     being sold,

                                       59
<PAGE>

               (7)  restrictions on transfer contained in Capital Expenditure
     Indebtedness incurred pursuant to clause (a) of Section 4.11; provided,
     that such restrictions relate only to the transfer of the property financed
     with the proceeds of such Capital Expenditure Indebtedness, and

               (8)  in connection with and pursuant to permitted Refinancings,
     replacements of restrictions imposed pursuant to clauses (1), (3), (4) or
     (7) or this clause (8) of this paragraph that are not more restrictive than
     those being replaced and do not apply to any other Person or assets than
     those that would have been covered by the restrictions in the Indebtedness
     so refinanced, and

               (9)  solely with respect to Non-Guarantor Subsidiaries,
     restrictions under the organizational documents governing such Subsidiary:

                    (a)  with respect to existing Non-Guarantor Subsidiaries,
existing on the Issue Date, and

                    (b)  with respect to Non-Guarantor Subsidiaries created
after the Issue Date:

                         (i)   prohibiting such Subsidiary from guaranteeing
          Indebtedness of the Company or another Subsidiary,

                         (ii)  on dividend payments and other distributions
          solely to permit pro rata dividends and other distributions in respect
          of any Equity Interests of such Subsidiary, and

                         (iii) with respect to clauses (y) and (z) above,
          limiting such transactions to those with terms that are fair and
          reasonable to such Subsidiary and no less favorable to such Subsidiary
          than could have been obtained in an arm's length transaction with an
          unrelated third party.

          Notwithstanding the foregoing, in the case of clause (y) above,
encumbrances or restrictions (A) that restrict in a customary manner the
subletting, assignment or transfer of any property or asset that is subject to a
lease, license or similar contract entered into in the ordinary course of
business, or the assignment or transfer of any lease, license or contract
entered into in the ordinary course of business, (B) by virtue of any transfer
of, agreement to transfer, option or right with respect to, or Lien on, any
property or assets of the Company or any Subsidiary not otherwise prohibited by
this Indenture in respect of the assets subject thereto or (C) contained in
security agreements or mortgages securing Indebtedness to the extent such
encumbrances or restrictions restrict the transfer of the property subject to
such security agreements or mortgages may be subject to customary restrictions
on the transfer or disposition thereof pursuant to such Lien.

SECTION 4.13.  LIMITATIONS ON LAYERING INDEBTEDNESS

                                       60
<PAGE>

          The Company and the Guarantors shall not, and neither the Company nor
the Guarantors shall permit any of their respective Subsidiaries to, directly or
indirectly, incur, create, issue, assume, guarantee or otherwise become liable
for any Indebtedness that is contractually subordinate in right of payment to
any of the Company's other Indebtedness or any other Indebtedness of a Guarantor
unless, by its terms, such Indebtedness is contractually subordinate in right of
payment to, or ranks pari passu with, the Notes or the Guarantee, as applicable.

SECTION 4.14.  LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK

          The Company and the Guarantors shall not, and neither the Company nor
the Guarantors shall permit any of their respective Subsidiaries to, in one or a
series of related transactions, convey, sell, lease, transfer, assign or
otherwise dispose of, directly or indirectly, any of their property, business or
assets, including by merger or consolidation (in the case of a Guarantor or one
of the Company's Subsidiaries), and including any sale or other transfer or
issuance of any Equity Interests of any of the Company's Subsidiaries or
Unrestricted Subsidiaries, whether by the Company or one of its Subsidiaries or
Unrestricted Subsidiaries or through the issuance, sale or transfer of Equity
Interests by one of the Company's Subsidiaries or Unrestricted Subsidiaries and
including any sale and leaseback transaction (any of the foregoing, an "Asset
Sale"), unless:

               (1)  (a) the Net Cash Proceeds therefrom (the "Asset Sale Offer
     Amount") are applied within 365 days after the date of such Asset Sale, to
     the extent not applied in accordance with paragraph (b) below, to the:

                         (i)   optional redemption of the Notes in accordance
          with the terms of this Indenture and the Company's other Indebtedness
          ranking on a parity with the Notes and with similar provisions
          requiring the Company to redeem such Indebtedness with the proceeds
          from such Asset Sale, pro rata in proportion to the respective
          principal amounts (or accreted values in the case of Indebtedness
          issued with an original issue discount) of the Notes and such other
          Indebtedness then outstanding, or

                         (ii)  repurchase of the Notes and such other
          Indebtedness ranking on a parity with the Notes and with similar
          provisions requiring the Company to make an offer to purchase such
          Indebtedness with the proceeds from such Asset Sale pursuant to a cash
          offer (subject only to conditions required by applicable law, if any)
          (pro rata in proportion to the respective principal amounts (or
          accreted values in the case of Indebtedness issued with an original
          issue discount) of the Notes and such other Indebtedness then
          outstanding) (the "Asset Sale Offer") at a purchase price of 100% of
          the principal amount (or accreted value in the case of Indebtedness
          issued with an original issue discount) (the "Asset Sale Offer Price")
          together with accrued and unpaid interest and Liquidated Damages, if
          any, to the date of payment, made within 335 days of such Asset Sale,
          or

                                       61
<PAGE>

                    (b)  within 365 days following such Asset Sale, the Asset
Sale Offer Amount is:

                         (i)  invested in assets or property (other than notes,
          bonds, obligations and securities, except in connection with the
          acquisition of a Wholly Owned Subsidiary that immediately becomes a
          Guarantor in a Related Business) which will constitute or be a part of
          a Related Business of the Company or such Subsidiary (if it continues
          to be a Subsidiary) immediately following such transaction or

                         (ii) used to retire Senior Debt and to permanently
          reduce the amount of such Senior Debt outstanding on the Issue Date or
          permitted pursuant to paragraphs (b) and (c) of Section 4.11
          (including that in the case of a revolver or similar arrangement that
          makes credit available, such commitment is so permanently reduced by
          such amount);

provided, however, that with respect to any Asset Sale occurring during 2001,
the Asset Sale Offer Amount received therefrom may be applied as provided in (a)
or (b) above at any time prior to December 31, 2002, and any Asset Sale Offer
made in accordance with (a)(ii) above may be made at any time prior to December
1, 2002,

               (2)  at least 75% of the total consideration for such Asset Sale
     or series of related Asset Sales consists of cash or Cash Equivalents,
     provided, that up to one-third of such 75% may consist of notes or other
     obligations received by the Company or such Subsidiary from such transferee
     that are converted by the Company or such Subsidiary into cash (to the
     extent of the cash received) within 365 days after receipt, which shall
     constitute Net Cash Proceeds attributable to the original Asset Sale for
     which such notes or other obligations were received, and provided further
     that any Indebtedness of the Company or any Subsidiary (as shown on the
     Company's or such Subsidiary's most recent balance sheet), other than
     Subordinated Indebtedness, that is assumed by the transferee of any such
     assets shall constitute cash for purposes hereof, so long as the Company
     and all of its Subsidiaries are fully and unconditionally released
     therefrom, and

               (3)  the Company or such Subsidiary, as applicable, receives fair
     market value for such Asset Sale, such determination to be made in good
     faith by the Company's Board of Directors, for Asset Sales exceeding
     $25,000,000.

          Pending the final application of any Net Cash Proceeds, the Company
may temporarily reduce revolving credit borrowings or otherwise invest the Net
Cash Proceeds in any manner that is not prohibited by this Indenture.

          An acquisition of Notes pursuant to an Asset Sale Offer may be
deferred until the accumulated Net Cash Proceeds from Asset Sales not applied to
the uses and in the time periods set forth in 1(a)(i) or 1(b) above (the "Excess
Proceeds") exceeds $10,000,000 and that each Asset Sale

                                       62
<PAGE>

Offer shall remain open for at least 20 Business Days following its commencement
(the "Asset Sale Offer Period").

          Upon expiration of the Asset Sale Offer Period, the Company shall
apply the Asset Sale Offer Amount plus an amount equal to accrued and unpaid
interest and Liquidated Damages, if any, to the purchase of all Indebtedness
properly tendered in accordance with the provisions hereof (on a pro rata basis
if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so
tendered) at the Asset Sale Offer Price (together with accrued interest and
Liquidated Damages, if any). To the extent that the aggregate amount of Notes
and such other pari passu Indebtedness tendered pursuant to an Asset Sale Offer
is less than the Asset Sale Offer Amount, the Company may use any remaining Net
Cash Proceeds for general corporate purposes as otherwise permitted by this
Indenture and following the consummation of each Asset Sale Offer the Excess
Proceeds amount shall be reset to zero.

          Notwithstanding, and without complying with, the provisions of this
covenant:

               (1)  the Company may and its Subsidiaries may, in the ordinary
     course of business, (a) convey, sell, transfer, assign or otherwise dispose
     of inventory and other assets acquired and held for resale in the ordinary
     course of business and (b) liquidate Cash Equivalents,

               (2)  the Company may and its Subsidiaries may convey, sell,
     transfer, assign or otherwise dispose of assets pursuant to and in
     accordance with Article V,

               (3)  the Company may and its Subsidiaries may sell or dispose of
     damaged, worn out surplus or obsolete personal property in the ordinary
     course of business so long as such property is no longer necessary for the
     proper conduct of the Company's business or the business of such
     Subsidiary, as applicable,

               (4)  the Company may and its Subsidiaries may convey, sell,
     lease, transfer, assign or otherwise dispose of assets to the Company or
     any of the Guarantors,

               (5)  the Company may and its Subsidiaries may, in the ordinary
     course of business, convey, sell, lease, transfer, assign, or otherwise
     dispose of assets (or related assets in related transactions) with a fair
     market value of less than $1,000,000,

               (6)  the Company may and each of its Subsidiaries may settle or
     release litigation claims in the ordinary course of business or grant Liens
     not prohibited by this Indenture,

               (7)  the Company may and its Subsidiaries may exchange assets
     held by the Company or such Subsidiaries for assets held by any Person or
     entity; provided, that (a) at the time of or when entering into any such
     exchange of assets and immediately after giving effect thereto, no Default
     or Event of Default shall have occurred and be continuing or would

                                       63
<PAGE>

     occur as a consequence thereof, (b) the assets received by the Company or
     such Subsidiaries in any such exchange will immediately constitute, be a
     part of, or be used in, a Related Business of the Company or such
     Subsidiaries, (c) with respect to transactions involving assets with a fair
     market value of $25,000,000 or more, the Company's Board of Directors has
     determined that the terms of any exchange are fair and reasonable, and (d)
     any such exchange shall be deemed to be an Asset Sale to the extent that
     the Company or any of the Company's Subsidiaries receives cash or Cash
     Equivalents in such exchange, and

               (8)  the Company and its Subsidiaries may enter into operating
     leases of real or personal property in the ordinary course of business.

          In addition to the foregoing and notwithstanding anything herein to
the contrary, the Company will not, and will not permit any of its Subsidiaries
to, directly or indirectly, make any Asset Sale of any of the Equity Interests
of any of its Subsidiaries (other than to the Company or to a Wholly Owned
Subsidiary that is a Guarantor) except (i) pursuant to an Asset Sale of all the
Equity Interests of such Subsidiary or (ii) provided, that after such sale the
Company or its Subsidiaries own a majority of the voting and economic Equity
Interests of such Subsidiary, an Asset Sale of Equity Interests with no
preferences or special rights or privileges and with no redemption or prepayment
provisions, or (iii) up to $10,000,000 in the aggregate per fiscal year, not to
exceed $50,000,000 in the aggregate, of sales of Equity Interests in excess of
50% of the Equity Interests of such Subsidiary, provided, that (x) such
Subsidiary exists solely for the purpose of owning and operating one or more
dialysis centers and providing services related thereto, (y) the Company or its
Subsidiaries own at least 20% of the voting and economic Equity Interests in
such Subsidiary after such Asset Sale, and (z) the Company or any of its
Subsidiaries enter into a management contract with respect to all of the
dialysis centers owned by the Subsidiary that was the subject of the Asset Sale.
In the case of clause (iii) of the preceding sentence, to the extent that the
aggregate amount available for sales of Equity Interests has been reduced as a
result of such sales, and the Company, a Guarantor or a Non-Guarantor Subsidiary
thereafter shall either (A) sell in an Asset Sale in compliance with the
provisions of this covenant all of the remaining Equity Interests in such
Subsidiary owned by the Company and its Subsidiaries or (B) repurchase Equity
Interests of such Subsidiary such that the Company, a Guarantor and/or a
Non-Guarantor Subsidiary own(s) in the aggregate in excess of 50% of the Equity
Interests of such Subsidiary upon repurchase, then an amount equal to the sales
price received for such Equity Interests sold in the case of clause (A), or the
purchase price paid for such Equity Interests so repurchased in the case of
clause (B), in either case as determined in good faith, shall increase the
aggregate amount available for future sales under such clause (iii); provided,
that

          (a)  the amount added back to the aggregate amount shall not exceed
the amount originally deducted therefrom upon the original sale of the Equity
Interests in such Subsidiary;

          (b)  the aggregate amount available shall in no event exceed
$50,000,000 at any time;

<PAGE>

               (c)  the aggregate amount available per year shall in no event
     exceed $10,000,000 in any year; and

               (d)  to the extent a Non-Guarantor Subsidiary repurchases such
     Equity Interests, such repurchase shall be deemed a formation of a
     Non-Guarantor Subsidiary on the date of repurchase for purposes of the
     definition of Non-Guarantor Subsidiary.

          Any Asset Sale Offer shall be made in compliance with all applicable
laws, rules, and regulations, including, if applicable, Regulation 14E of the
Exchange Act and the rules and regulations thereunder and all other applicable
federal and state securities laws. To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this paragraph,
the Company's compliance or the compliance of any of the Company's subsidiaries
with such laws and regulations shall not in and of itself cause a breach of the
Company's obligations under this Section 4.14.

          If the payment date in connection with an Asset Sale Offer hereunder
is on or after an interest payment Record Date and on or before the associated
Interest Payment Date, any accrued and unpaid interest (and Liquidated Damages,
if any) due on such Interest Payment Date will be paid to the Person in whose
name a Note is registered at the close of business on such Record Date on the
corresponding Interest Payment Date.

          Notice of an Asset Sale Offer shall be sent, on or prior to the
commencement of the Asset Sale Offer, by first-class mail, by the Company to
each Holder at its registered address, with a copy to the Trustee. At the
Company's request, the Paying Agent shall give the notice of Asset Sale Offer in
the Company's name and at the Company's expense. The notice to the Holders shall
contain all information, instructions and materials required by applicable law
or which the Company in good faith believes will enable such Holders to make an
informed decision with respect to the Asset Sale Offer. The notice, which (to
the extent consistent with this Indenture) shall govern the terms of an Asset
Sale Offer, shall state:

               (1)  that the Asset Sale Offer is being made pursuant to such
     notice and this Section 4.14;

               (2)  the Asset Sale Offer Amount, the Asset Sale Offer Price
     (including the amount of accrued but unpaid interest (and Liquidated
     Damages, if any)), and the date of purchase;

               (3)  that any Note or portion thereof not tendered or accepted
     for payment will continue to accrue interest (and Liquidated Damages, if
     any) if interest (and Liquidated Damages, if any) is then accruing;

               (4)  that, unless the Company defaults in depositing cash with
     the Paying Agent (which may not for purposes of this Section 4.14,
     notwithstanding anything in this Indenture to the contrary, be the Company
     or any Affiliate of the Company) in accordance

                                       65
<PAGE>

     with the last paragraph of this Section 4.14, any Note, or portion thereof,
     accepted for payment pursuant to the Asset Sale Offer shall cease to accrue
     interest (and Liquidated Damages, if any) after the payment date in
     connection with an Asset Sale Offer;

               (5)  that Holders electing to have a Note, or portion thereof,
     purchased pursuant to an Asset Sale Offer will be required to surrender
     their Note, with the form entitled "Option of Holder to Elect Purchase" on
     the reverse of the Note completed, to the Paying Agent (which may not for
     purposes of this Section 4.14, notwithstanding any other provision of this
     Indenture, be the Company or any Affiliate of the Company) prior to the
     close of business on the date specified in the notice, which shall not be
     earlier than the date on which the Asset Sale Offer expires, at the address
     specified in the notice;

               (6)  that Holders will be entitled to withdraw their elections,
     in whole or in part, if the Paying Agent receives, prior to the expiration
     of the Asset Sale Offer, a facsimile transmission or letter setting forth
     the name of the Holder, the principal amount of the Notes the Holder is
     withdrawing and a statement containing a facsimile signature and stating
     that such Holder is withdrawing his election to have such principal amount
     of the Notes purchased;

               (7)  that if Indebtedness in an aggregate principal amount in
     excess of the aggregate principal amount of Notes to be acquired pursuant
     to the Asset Sale Offer are tendered and not withdrawn, the Company shall
     purchase Indebtedness on a pro rata basis in proportion to the respective
     principal amounts (or accreted values in the case of Indebtedness issued
     with an original issue discount) thereof (with such adjustments as may be
     deemed appropriate by the Company so that only Notes in denominations of
     $1,000 or integral multiples of $1,000 shall be acquired);

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

               (9)  the circumstances and relevant facts regarding such Asset
     Sales.

          On or before the date of purchase, the Company shall (i) accept for
payment Notes or portions thereof properly tendered pursuant to the Asset Sale
Offer (on a pro rata basis if required pursuant to paragraph (7) above), (ii)
deposit with the Paying Agent cash sufficient to pay the Asset Sale Offer Price
for all Notes or portions thereof so accepted and (iii) deliver to the Trustee
Notes so accepted together with an Officers' Certificate setting forth the Notes
or portions thereof being purchased by the Company. The Paying Agent shall
promptly mail or deliver to Holders of Notes so accepted payment in an amount
equal to the Asset Sale Offer Price for such Notes, and the Trustee shall
promptly authenticate and mail or deliver to such Holders a new Note equal in
principal amount to any unpurchased portion of the Note surrendered. Any Notes
not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof.

SECTION 4.15.  WAIVER OF STAY, EXTENSION OR USURY LAWS

          Each of the Company and the Guarantors covenants (to the extent that
it may lawfully do so) that it shall not at any time insist upon, plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or other law which would prohibit or forgive the
Company or any Guarantor from paying all or any portion of the principal of,
premium of, or interest (or Liquidated Damages, if any) on the Notes as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so) each of the Company and the Guarantors hereby
expressly waives all benefit or advantage of any such law, and covenants that it
shall not hinder, delay or impede the execution of any power herein granted to
the Trustee, but shall suffer and permit the execution of every such power as
though no such law had been enacted.

SECTION 4.16.  LIMITATION ON LIENS SECURING INDEBTEDNESS

          The Company and the Guarantors shall not, and neither the Company nor
the Guarantors shall permit any of their respective Subsidiaries to, create,
incur, assume or suffer to exist any Lien of any kind, other than Permitted
Liens, upon any of their respective assets now owned or acquired on or after the
date of this Indenture or upon any income or profits therefrom securing any
Indebtedness of the Company, or any Indebtedness of any Guarantor, unless the
Company provides, and causes its Subsidiaries to provide, concurrently
therewith, that the Notes and the applicable Guarantees are equally and ratably
so secured, provided that if such Indebtedness is Subordinated Indebtedness, the
Lien securing such Subordinated Indebtedness shall be contractually subordinate
and junior to the Lien securing the Notes (and any related applicable
Guarantees) with the same relative priority as such Subordinated Indebtedness
shall have with respect to the Notes (and any related applicable Guarantees).

SECTION 4.17.  LIMITATIONS ON LINES OF BUSINESS

          Neither the Company nor any of its Subsidiaries shall directly or
indirectly engage to any substantial extent in any line or lines of business
activity other than that which is a Related Business.

SECTION 5.1.   LIMITATION ON MERGER, SALE OR CONSOLIDATION

          The Company will not consolidate with or merge with or into another
Person or, directly or indirectly, sell, lease, convey or transfer all or
substantially all of its assets (such amounts to be computed on a consolidated
basis), whether in a single transaction or a series of related transactions, to
another Person or group of affiliated Persons, unless:

<PAGE>

               (1)  either (a) the Company is the continuing entity or (b) the
     resulting, surviving or transferee entity is a corporation organized under
     the laws of the United States, any state thereof or the District of
     Columbia and expressly assumes by supplemental indenture all of the
     Company's obligations in connection with the Notes and this Indenture;

               (2)  no Default or Event of Default shall exist or shall occur
     immediately after giving effect on a pro forma basis to such transaction;

               (3)  unless such transaction is solely the merger of the Company
     and one of its previously existing Subsidiaries and which transaction is
     not for the purpose of evading this provision and not in connection with
     any other transaction, immediately after giving effect to such transaction
     on a pro forma basis, the consolidated resulting, surviving or transferee
     entity would immediately thereafter be permitted to incur at least $1.00 of
     additional Indebtedness pursuant to the Debt Incurrence Ratio set forth in
     Section 4.11; and

               (4)  each Guarantor shall have by amendment to this Indenture
     confirmed that its Guarantee shall apply to the obligations of the Company
     or the surviving entity in accordance with the Notes and this Indenture.

          For purposes of the foregoing, the transfer (by lease, assignment,
sale or otherwise) of all or substantially all of the properties and assets of
one or more Subsidiaries of the Company, the Company's interest in which
constitutes all or substantially all of the Company's properties and assets,
shall be deemed to be the transfer of all or substantially all of the Company's
properties and assets.

SECTION 5.2.   SUCCESSOR CORPORATION SUBSTITUTED

          Upon any consolidation or merger or any transfer of all or
substantially all of the assets of the Company in accordance with Section 5.1,
the successor corporation formed by such consolidation or into which the Company
is merged or to which such transfer is made, shall succeed to and (except in the
case of a lease) be substituted for, and may exercise every right and power of,
the Company under this Indenture with the same effect as if such successor
corporation had been named herein as the Company, and (except in the case of a
lease) when a successor corporation duly assumes all of the obligations of the
Company pursuant hereto and pursuant to the Notes, the Company shall be released
from such obligations (except with respect to any obligations that arise from,
or are related to, such transaction).

     stated maturity,

                    (vii)  final unsatisfied judgments not covered by insurance

                    (viii) any Guarantee of a Guarantor ceases to be in full
     force and effect or becomes unenforceable or invalid or is declared null
     and void or any Guarantor denies or disaffirms its obligations under its

     Guarantee and this Indenture.

SECTION 6.2.   ACCELERATION OF MATURITY DATE; RESCISSION AND ANNULMENT

          If an Event of Default occurs and is continuing (other than an Event
of Default specified in Section 6.1(iv) or Section 6.1(v) above relating to the
Company or any of its Significant Subsidiaries), then, and in every such case,
unless the principal of all of the Notes shall have already become due and
payable, either the Trustee or the Holders of at least 25% in aggregate
principal amount of then outstanding Notes, by notice in writing to the Company
(and to the Trustee if given by Holders) (an "Acceleration Notice"), may declare
all principal, determined as set forth below, and accrued interest (and
Liquidated Damages, if any) thereon to be due and payable immediately, provided,
however, that if any Senior Debt is outstanding pursuant to the Credit
Agreement, upon a declaration of such acceleration, such principal and interest
shall be due and payable upon the earlier of (x) the fifth Business Day after
sending the Company and such Senior Debt representatives such written notice,
unless such Event of Default is cured or waived prior to such date and (y) the
date of acceleration of any Senior Debt under the Credit Agreement.

          In the event a declaration of acceleration resulting from an Event of
Default described in Section 6.1(vi) above with respect to any Senior Debt has
occurred and is continuing, such declaration of acceleration shall be
automatically annulled if such default is cured or waived or the holders of the
Indebtedness which is the subject of such default have rescinded their
declaration of acceleration in respect of such Indebtedness within 10 days
thereof and the Trustee has received written notice of such cure, waiver or
rescission and no other Event of Default described in clause (vi) above has
occurred that has not been cured or waived within 10 days of the declaration of
such acceleration in respect of such Indebtedness.

                                       70
<PAGE>

          If an Event of Default specified in Section 6.1(iv) or Section 6.1(v)
above relating the Company or any of its Significant Subsidiaries occurs, all
principal and accrued interest (and Liquidated Damages, if any) thereon will be
immediately due and payable on all outstanding Notes without any declaration or
other act on the part of the Trustee or the Holders.

          The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default (except nonpayment of principal of,
premium, if any, interest or Liquid Damages, if any, that has become due solely
because of the acceleration) have been cured or waived as provided in Section
6.12.

SECTION 6.3.   COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE

          The Company covenants that if an Event of Default in payment of
principal, premium or interest specified in clause (i) or (ii) of Section 6.1
hereof occurs and is continuing, the Company shall, upon demand of the Trustee,
pay to it, for the benefit of the Holders of such Notes, the whole amount then
due and payable on such Notes for principal, premium (if any), and interest (and
Liquidated Damages, if any), and, to the extent that payment of such interest
shall be legally enforceable, interest on any overdue principal (and premium, if
any), and on any overdue interest (and Liquidated Damages, if any), at the rate
borne by the Notes, and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including compensation
to, and expenses, disbursements and advances of the Trustee and its agents and
counsel and all other amounts due the Trustee under Section 7.7.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust in favor of the
Holders, may institute a judicial proceeding for the collection of the sums so
due and unpaid, may prosecute such proceeding to judgment or final decree and
may enforce the same against the Company or any other obligor upon the Notes and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon the Notes,
wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 6.4.   TRUSTEE MAY FILE PROOFS OF CLAIM

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the Notes
or the property of the Company or of such other

                                       71
<PAGE>

obligor or their creditors, the Trustee (irrespective of whether the principal
of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand on the Company for the payment of overdue principal, premium, if any,
or interest (and Liquidated Damages, if any)) shall be entitled and empowered,
by intervention in such proceeding or otherwise to take any and all actions
under the TIA, including

               (1)  to file and prove a claim for the whole amount of principal
     (and premium, if any) and interest (and Liquidated Damages, if any) owing
     and unpaid in respect of the Notes and to file such 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 and its agent and counsel and all
     other amounts due the Trustee under Section 7.7) and of the Holders allowed
     in such judicial proceeding, and

               (2)  to collect and receive any moneys or other property payable
     or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the compensation, expenses,
disbursements and advances of the Trustee and its agents and counsel, and any
other amounts due the Trustee under Section 7.7 hereof.

          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 thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding; provided, however, that the
Trustee may, on behalf of the Holders, vote for the election of a Trustee in
bankruptcy or a similar official and may be a member of any creditor's committee
approved in such matter.

SECTION 6.5.   TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF NOTES

          All rights of action and claims under this Indenture or the Notes may
be prosecuted and enforced by the Trustee without the possession of any of the
Notes or the production thereof in any proceeding relating thereto, and any such
proceeding instituted by the Trustee shall be brought in its own name as trustee
of an express trust in favor of the Holders, and any recovery of judgment shall,
after provision for the payment of compensation to, and expenses, disbursements
and advances of the Trustee and its agents and counsel and all other amounts due
the Trustee under Section 7.7, be for the ratable benefit of the Holders of the
Notes in respect of which such judgment has been recovered.

SECTION 6.6.   PRIORITIES

                                       72
<PAGE>

          Any money collected by the Trustee pursuant to this Article VI shall
be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal, premium

Notes and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

          FIRST: To the Trustee in payment of all amounts due pursuant to
Section 7.7 hereof;

          SECOND: To the holders of Senior Debt if and to the extent required by
Articles XI and XII;

          THIRD: To the Holders in payment of the amounts then due and unpaid

any) on, the Notes in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on such Notes for principal, premium
(if any), and interest (and Liquidated Damages, if any), respectively; and

          FOURTH: To the Company, the Guarantors or such other Person as may be
lawfully entitled thereto, the remainder, if any, each as their respective
interests may appear.

          The Trustee may, but shall not be obligated to, fix a record date and
payment date for any payment to the Holders under this Section 6.6.

SECTION 6.7.   LIMITATION ON SUITS

          No Holder of any Note shall have any right to order or direct the
Trustee to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless

                    (A)   such Holder has previously given written
          notice to the Trustee of a continuing Event of Default;

                    (B)   the Holders of not less than 25% in
          aggregate principal amount of then outstanding Notes shall
          have made written request to the Trustee to institute
          proceedings in respect of such Event of Default in its own
          name as Trustee hereunder;

                    (C)   such Holder or Holders have offered to the
          Trustee reasonable security or indemnity against the costs,
          expenses and liabilities to be incurred or reasonably
          probable to be incurred in compliance with such request;

                                       73
<PAGE>

                    (D)   the Trustee for 60 days after its receipt of
          such notice, request and offer of indemnity has failed to
          institute any such proceeding; and

                    (E)   no direction inconsistent with such written
          request has been given to the Trustee during such 60-day
          period by the Holders of a majority in aggregate principal
          amount of the outstanding Notes;

it being understood and intended that no one or more Holders shall have any
right in any manner whatsoever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

SECTION 6.8.   UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND
               INTEREST

          Notwithstanding any other provision of this Indenture, the Holder of
any Note shall have the right, which, subject to the provisions of Section 11.5
and Article XII, is absolute and unconditional, to receive payment of the
principal of, and premium (if any), and interest (and Liquidated Damages, if
any) on, such Note on the Maturity Dates of such payments as expressed in such
Note (in the case of redemption, the Redemption Price on the applicable
Redemption Date, in the case of a Change of Control, the Change of Control
Purchase Price on the Change of Control Purchase Date, and in the case of an
Asset Sale, the Asset Sale Offer Price on the relevant purchase date) and to
institute suit for the enforcement of any such payment after such respective
dates, and such rights shall not be impaired without the consent of such Holder.

SECTION 6.9.   RIGHTS AND REMEDIES CUMULATIVE

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Notes in Section 2.7 hereof, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

SECTION 6.10.  DELAY OR OMISSION NOT WAIVER

          No delay or omission by the Trustee or by any Holder of any Note to
exercise any right or remedy arising upon any Event of Default shall impair the
exercise of any such right or remedy or constitute a waiver of any such Event of
Default. Every right and remedy given by this

                                       74
<PAGE>

Article VI or by law to the Trustee or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

SECTION 6.11.  CONTROL BY HOLDERS

          The Holder or Holders of a majority in aggregate principal amount of
then outstanding Notes shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred upon the Trustee, provided, that

               (1)  such direction shall not be in conflict with any rule of law
     or with this Indenture,

               (2)  the Trustee shall not determine that the action so directed
     would be unjustly prejudicial to the Holders not taking part in such
     direction, and

               (3)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction.

SECTION 6.12.  WAIVER OF EXISTING OR PAST DEFAULT

          Subject to Section 6.8, the Holder or Holders of not less than a
majority in aggregate principal amount of the outstanding Notes may, on behalf
of all Holders, waive any existing or past Default or Event of Default hereunder
and its consequences under this Indenture, except a continuing Default or Event
of Default

                    (A)   in the payment of the principal of, premium,
          if any, or interest (or Liquidated Damages, if any) on, any
          Note as specified in clauses (i) and (ii) of Section 6.1
          hereof and not yet cured, or

                    (B)   in respect of a covenant or provision hereof
          which, under Article IX, cannot be modified or amended
          without the consent of the Holders of each outstanding Note
          affected.

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

SECTION 6.13.  UNDERTAKING FOR COSTS

          All parties to this Indenture agree, and each Holder of any Note by
his acceptance thereof shall be deemed to have agreed, that in any suit for the
enforcement of any right or remedy

                                       75
<PAGE>

under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted to be taken by it as Trustee, any court may in its
discretion require the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section 6.13 shall not apply to any suit instituted by
the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in
aggregate principal amount of the outstanding Notes, or to any suit instituted
by any Holder for enforcement of the payment of principal of, or premium (if
any), or interest (or Liquidated Damages, if any) on, any Note on or after the
respective Maturity Date expressed in such Note (including, in the case of
redemption, on or after the Redemption Date).

SECTION 6.14.  RESTORATION OF RIGHTS AND REMEDIES

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Guarantors, the Trustee and
the Holders shall be restored severally and respectively to their former
positions hereunder and thereafter all rights and remedies of the Trustee and
the Holders shall continue as though no such proceeding had been instituted.

                                  ARTICLE VII

                                    TRUSTEE

          The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed, subject to
the terms hereof.

SECTION 7.1.   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 their exercise as a
prudent Person would exercise or use under the circumstances in the conduct of
his or her own affairs.

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

               (1)  The Trustee need perform only those duties as are
     specifically set forth in this Indenture and no others, and no covenants or
     obligations shall be implied in or read into this Indenture which are
     adverse to the Trustee, and

                                       76
<PAGE>

               (2)  In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     in the case of any such certificates or opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of mathematical calculations or other
     facts stated therein or otherwise verify the contents thereof).

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

               (1)  This paragraph does not limit the effect of paragraph (b) of
     this Section 7.1,

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

               (3)  The Trustee shall not be liable with respect to any action
     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.11 hereof.

          (d)  No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or at the request, order or direction of the Holders or in
the exercise of any of its rights or powers if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.

          (e)  Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section 7.1.

          (f)  The Trustee shall not be liable for interest on any assets
received by it except as the Trustee may agree in writing with the Company
(including without limitation to the extent the Trustee receives funds prior to
the interest payment date in order to comply with the provisions of Section
4.1). Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

SECTION 7.2.   RIGHTS OF TRUSTEE

          Subject to Section 7.1 hereof:

                                       77
<PAGE>

          (a)  The Trustee may rely on any document reasonably believed by it to
be genuine and to have been signed or presented by the proper Person. The
Trustee need not investigate any fact or matter stated in such document.

          (b)  Before the Trustee acts or refrains from acting, it may consult
with counsel and may require an Officers' Certificate or an Opinion of Counsel,
which shall conform to Sections 13.4 and 13.5 hereof. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such certificate or, if in writing, advice of counsel.

          (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.

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

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

          (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, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

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

          (h)  The Trustee shall have no duty to inquire as to the performance
of the Company's or any Guarantor's covenants in Article IV hereof or as to the
performance by any Agent of its duties hereunder. In addition, the Trustee shall
not be deemed to have knowledge of any Default or Event of Default except (i)
any Event of Default occurring pursuant to Sections 6.1(i), 6.1(ii) and 4.1
hereof, or (ii) any Default or Event of Default of which the Trustee shall have
received written notification or obtained actual knowledge.

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

                                       78
<PAGE>

          (j)  No permissive right of the Trustee to act hereunder shall be
construed as a duty.

          (k)  The Trustee shall not be deemed to have notice or knowledge
(including actual knowledge) of any matter unless a Trust Officer has actual
knowledge thereof or unless written notice thereof is received by the Trustee at
the office specified in Section 13.2 and such notice references the Notes
generally, the Company or this Indenture.

SECTION 7.3.   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, any
Guarantor, any of their Subsidiaries, or their respective Affiliates with the
same rights it would have if it were not Trustee. Any Agent may do the same with
like rights. However, the Trustee must comply with Sections 7.10 and 7.11
hereof.

SECTION 7.4.   TRUSTEE'S DISCLAIMER

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Notes and it shall not be accountable for the Company's
use of the proceeds from the Notes, and it shall not be responsible for any
statement or recital herein or any other document in connection with the sale of
the Notes, other than the Trustee's certificate of authentication, or the use or
application of any funds received by a Paying Agent other than the Trustee.

SECTION 7.5.   NOTICE OF DEFAULT

          If a Default or an Event of Default occurs and is continuing and if it
is known to the Trustee, the Trustee shall mail to each Securityholder notice of
the uncured Default or Event of Default within 90 days after such Default or
Event of Default occurs. The Trustee may withhold such notice if and so long as
a Trust Officer in good faith determines that withholding the notice is in the
interest of the Holders, except in the case of a Default in payment of principal
(or premium, if any) of, interest on or Liquidated Damages with respect to, any
Notes (including the repayment of the Redemption Price on the Redemption Date).

SECTION 7.6.   REPORTS BY TRUSTEE TO HOLDERS

          Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, the Trustee shall, if required by law, mail to each
Securityholder a brief report dated as of such May 15 that complies with TIA (S)
313(a). The Trustee also shall comply with TIA (S)(S) 313(b) and 313(c).

          The Company shall promptly notify the Trustee in writing if the Notes
become listed on any stock exchange or automatic quotation system.

                                       79
<PAGE>

          A copy of each report at the time of its mailing to Securityholders
shall be mailed to the Company and filed with the SEC and each stock exchange,
if any, on which the Notes are listed.

SECTION 7.7.  COMPENSATION AND INDEMNITY

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

          The Company and the Guarantors jointly and severally agree to
indemnify the Trustee (in its capacity as Trustee) and each of its officers,
directors, attorneys-in-fact and agents for, and hold it harmless against, any
claim, demand, expense (including but not limited to reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel), loss or
liability incurred by it without negligence, bad faith or willful misconduct on
the part of the Trustee, arising out of or in connection with the administration
of this trust, including the costs and expenses of enforcement of this Indenture
against the Company and the Guarantors (including this Section 7.7), and its
rights or duties hereunder, including the reasonable costs and expenses of
defending itself against any claim (whether asserted by any Holder, the Company,
any Guarantor or third party) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, but excluding any
franchise taxes imposed on the Trustee and any taxes based on the income of the
Trustee. The Trustee shall notify the Company promptly of any claim asserted
against the Trustee for which it may seek indemnity. The Company and the
Guarantors shall defend the claim and the Trustee shall provide reasonable
cooperation at the Company's and the Guarantors' expense in the defense. The
Trustee may have separate counsel and the Company and the Guarantors shall pay
the reasonable fees and expenses of such counsel; provided, that the Company and
the Guarantors will not be required to pay such fees and expenses if they assume
the Trustee's defense and the Trustee is not advised in writing by counsel that
there is a conflict of interest between the Company and the Guarantors and the
Trustee in connection with such defense. The Company and the Guarantors need not
pay for any settlement made without their written consent, which consent shall
not be unreasonably withheld, delayed or conditioned. The Company and the
Guarantors need not reimburse any expense or indemnify against any loss or
liability to the extent incurred by the Trustee through its negligence, bad
faith or willful misconduct.

          To secure the Company's and the Guarantors' payment obligations in
this Section 7.7, the Trustee shall have a perfected lien prior to the Notes on
all assets held or collected by the Trustee, in its capacity as Trustee, except
assets held in trust to pay principal and premium, if any, of or interest on
particular Notes.

                                       80
<PAGE>

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(iv) or (v) of this Indenture occurs, the
expenses and the compensation for the services are intended to constitute
expenses of administration under any Bankruptcy Law.

          The Company's and the Guarantors' obligations under this Section 7.7
and any lien arising hereunder shall survive the resignation or removal of the
Trustee, the discharge of the Company's and the Guarantors' obligations pursuant
to Article VIII of this Indenture and any rejection or termination of this
Indenture under any Bankruptcy Law.

SECTION 7.8.   REPLACEMENT OF TRUSTEE

          The Trustee may resign by so notifying the Company in writing. The
Holder or Holders of a majority in aggregate principal amount of the outstanding
Notes may remove the Trustee by so notifying the Company and the Trustee in
writing and may appoint a successor trustee with the Company's consent. The
Company may remove the Trustee if:

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

          (b)  the Trustee is adjudged bankrupt or insolvent;

          (c)  a receiver, Custodian or other 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. No resignation of the Trustee and no appointment of a successor Trustee
pursuant to this Article VII shall become effective until the acceptance of
appointment by the successor Trustee under this Section 7.8. Within one year
after the successor Trustee takes office, the Holder or Holders of a majority in
principal amount of the Notes may appoint a successor Trustee to replace the
successor Trustee appointed by the Company.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that
and provided that all sums owing to the retiring Trustee provided for in Section
7.7 hereof have been paid, the retiring Trustee shall transfer all property held
by it as trustee to the successor Trustee, subject to the lien provided in
Section 7.7 hereof, 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. A successor Trustee shall mail
notice of its succession to each Holder.

          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
Holder or Holders of at least 10% in principal amount of the outstanding Notes
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

                                       81
<PAGE>

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

          Notwithstanding replacement of the Trustee pursuant to this Section
7.8, the Company's and the Guarantors' obligations under Section 7.7 hereof
shall continue for the benefit of the retiring Trustee.

SECTION 7.9.   SUCCESSOR TRUSTEE BY MERGER, ETC.

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION

          The Trustee shall at all times satisfy the requirements of TIA (S)
310(a)(1), (2) and (5). The Trustee shall have a combined capital and surplus of
at least $25,000,000 as set forth in its most recent published annual report of
condition. The Trustee shall comply with TIA (S) 310(b).

SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

          The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S) 311(b). A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated.

                                 ARTICLE VIII

                   LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.1.   OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE

          The Company may elect to have Section 8.2, at the Company's option and
at any time, or Section 8.3, at the Company's option and at any time, of this
Indenture applied to all outstanding Notes upon compliance with the conditions
set forth below in this Article VIII.

SECTION 8.2.   LEGAL DEFEASANCE AND DISCHARGE

          Upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.2, the Company and the Guarantors shall be deemed
to have been discharged from their respective obligations with respect to all
outstanding Notes and Guarantees on the date the

                                       82
<PAGE>

conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For
this purpose, such Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by the Notes and
this Indenture shall cease to be of further effect as to all outstanding Notes
and Guarantees, except as to be deemed to be "outstanding" only for the purposes
of the Sections of this Indenture referred to in (a) and (b) below, and the
Company and the Guarantors shall be deemed to have satisfied all other of their
respective obligations under such Notes and this Indenture (and the Trustee, on
demand of and at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder: (a) the rights of Holders of
outstanding Notes to receive payments in respect of the principal of, premium,
if any, and interest (and Liquidated Damages, if any) on such Notes when such
payments are due from the trust described in Section 8.5, (b) the Company's
obligations with respect to such Notes under Sections 2.4, 2.6, 2.7, 2.10, 4.2,
8.5, 8.6 and 8.7 hereof and (c) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and the Company's obligations in connection
therewith. Subject to compliance with this Article VIII, the Company may
exercise its option under this Section 8.2 notwithstanding the prior exercise of
its option under Section 8.3 hereof with respect to the Notes.

SECTION 8.3.   COVENANT DEFEASANCE

          Upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.3, the Company and the Guarantors shall be released
from their respective obligations under the covenants contained in Sections 4.3,
4.6, 4.7, 4.8, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16 and 4.17, Article V and
Article X hereof with respect to the outstanding Notes on and after the date the
conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"),
and 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. For this
purpose, such Covenant Defeasance means that, with respect to the outstanding
Notes, neither the Company nor any Guarantor need comply with and shall have any
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
6.1(iii), but, except as specified above, the remainder of this Indenture and
such Notes shall be unaffected thereby. In addition, upon the Company's exercise
under Section 8.1 hereof of the option applicable to this Section 8.3, and
subject to Section 8.4, Sections 6.1(vi) through 6.1(viii) hereof shall not
constitute Events of Default with respect to the Notes.

SECTION 8.4.   CONDITIONS TO LEGAL OR COVENANT DEFEASANCE

          The following shall be the conditions to the application of either
Section 8.2 or 8.3 hereof to the outstanding Notes:

                                       83
<PAGE>

          (a)  (i)  The Company shall irrevocably have deposited or caused to be
deposited with the Trustee, in trust, for the benefit of the Holders of the
Notes, U.S. legal tender, U.S. Government Obligations, or a combination thereof,
in such amounts as will be sufficient, in the opinion of a nationally recognized
firm of independent public accountants, to pay the principal of, premium, if
any, and interest (and Liquidated Damages, if any) on such outstanding Notes on
the stated date for payment thereof or on the redemption date of such principal
or installment of principal of, premium, if any, or interest (and Liquidated
Damages, if any) on such Notes, and the Holders of Notes must have a valid,
perfected, exclusive security interest in such trust, (ii) in the case of Legal
Defeasance, 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 such 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; (iii) in the case of Covenant Defeasance, the Company shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to such Trustee confirming that the Holders of such 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; (iv) no Default or Event
of Default shall have occurred and be continuing on the date of such deposit or
insofar as Events of Default from bankruptcy or insolvency events are concerned,
at any time in the period ending on the 91st day after the date of deposit; (v)
such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under this Indenture or any other material
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which the Company or any of its Subsidiaries is bound; (vi) 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 such Notes over the other creditors of the Company or with the intent
of defeating, hindering, delaying or defrauding the other creditors of the
Company or others; and (vii) the Company shall have delivered to the Trustee an
Officers' Certificate and an opinion of counsel, each stating that the
conditions precedent provided for in, in the case of the Officers' Certificate,
(i) through (vi) and, in the case of the opinion of counsel, clauses (i) (with
respect to the validity and perfection of the security interest), (ii), (iii)
and (v) of this paragraph, have been complied with and the Company shall have
delivered to the Trustee an Officers' Certificate, subject to such
qualifications and exceptions as the Trustee deems appropriate, to the effect
that, assuming no Holder of the Notes is an insider of the Company, the trust
funds will not be subject to the effect of any applicable federal bankruptcy,
insolvency, reorganization or similar laws affecting creditors' rights
generally.

          If the funds deposited with the Trustee to effect Covenant Defeasance
are insufficient to pay the principal of, premium, if any, and interest (and
Liquidated Damages, if any) on the Notes when due, then the obligations of the
Company and the Guarantors under this Indenture, will be revived and no such
defeasance will be deemed to have occurred.

SECTION 8.5.   DEPOSITED CASH AND U.S. GOVERNMENT OBLIGATIONS TO BE HELD IN
               TRUST; OTHER MISCELLANEOUS PROVISIONS

          Subject to Section 8.6 hereof, all cash and U.S. Government
Obligations (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 8.5, the
"Paying Agent") pursuant to Section 8.4 hereof in respect of the outstanding
Notes shall be held in trust and applied by the Paying Agent, in accordance with
the provisions of such Notes and this Indenture, to the payment, either directly
or through any other 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 (and Liquidated Damages, if any), 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 U.S. Government Obligations
deposited pursuant to Section 8.4 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 outstanding Notes.

SECTION 8.6.   REPAYMENT TO THE COMPANY

          (a)  Anything in this Article VIII to the contrary notwithstanding,
the Trustee or the Paying Agent shall deliver or pay to the Company from time to
time upon the request of the Company any cash or U.S. Government Obligations
held by it as provided in Section 8.4 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 8.4(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.

          (b)  Any cash and U.S. Government Obligations (including the proceeds
thereof) 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 (and Liquidated Damages, if any) on any Note and remaining unclaimed
for two years after such principal, and premium, if any, or interest (and
Liquidated Damages, if any) has become due and payable shall be paid to the
Company on its request (or if 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 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 be not
less than 30 days nor more than 90 days from the date of such notification or
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

SECTION 8.7.   REINSTATEMENT

                                       85
<PAGE>

          If the Trustee or Paying Agent is unable to apply any cash or U.S.
Government Obligations in accordance with Section 8.2 or 8.3 hereof, as the case
may be, of this Indenture by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the Guarantors' obligations under this
Indenture and the Notes shall be revived and reinstated as though no deposit had
occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or
Paying Agent is permitted to apply such money in accordance with Sections 8.2
and 8.3 hereof, as the case may be; provided, however, that, if the Company
makes any payment of principal of, premium, if any, or interest (and Liquidated
Damages, if any) on any Note following 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 cash or U.S. Government Obligations held by the
Trustee or Paying Agent.

                                  ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.1.   SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS

          Without the consent of any Holder, the Company or any Guarantor, when
authorized by Board Resolutions, and the Trustee, at any time and from time to
time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

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

               (2)  to add to the covenants of the Company or the Guarantors for
     the benefit of the Holders, or to surrender any right or power herein
     conferred upon the Company or the Guarantors or make any other change that
     does not materially adversely affect the rights of any Holder;

               (3)  to provide for collateral for or additional Guarantors of
     the Notes;

               (4)  to evidence the succession of another Person to the Company,
     and the assumption by any such successor of the obligations of the Company,
     herein and in the Notes in accordance with Article V;

               (5)  to comply with the TIA;

               (6)  to evidence the succession of another corporation to any
     Guarantor and assumption by any such successor of the Guarantee of such
     Guarantor (as set forth in Section 11.4) in accordance with Article XI;

                                       86
<PAGE>

               (7)  to evidence the release of any Guarantor in accordance with
     Article XI;

               (8)  to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee with respect to the Notes; or

               (9)  to provide for the issuance and authorization of the
     Exchange Notes.

SECTION 9.2.   AMENDMENTS, SUPPLEMENTAL INDENTURES AND WAIVERS WITH CONSENT OF
               HOLDERS

          Subject to Section 6.8 hereof, with the consent of the Holders of at
least a majority in aggregate principal amount of the Notes then outstanding
(including consents obtained in connection with a tender offer or exchange offer
for such Notes), by written act of said Holders delivered to the Company and the
Trustee, the Company and the Guarantors, when authorized by Board Resolutions,
and the Trustee may amend or supplement this Indenture or enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders under
this Indenture or the Notes. Subject to Section 6.8, the Holder or Holders of
not less than a majority in aggregate principal amount of then outstanding Notes
may waive compliance by the Company or any Guarantor with any provision of this
Indenture or the Notes. Notwithstanding any of the above, however, no such
amendment, supplemental indenture or waiver shall, without the consent of the
Holder of each outstanding Note affected thereby:

               (1)  change the Stated Maturity on any Note, or reduce the
     principal amount thereof or the rate (or extend the time for payment) of
     interest thereon or any premium payable upon the redemption thereof at the
     Company's option, or change the place of payment where, or the coin or
     currency in which, any Note or any premium or the interest thereon is
     payable, or impair the right to institute suit for the enforcement of any
     such principal, interest or premium payment thereon on or after the
     Maturity Date (or, in the case of redemption at the Company's option, on or
     after the Redemption Date), or reduce the Change of Control Purchase Price
     or the Asset Sale Offer Price after the corresponding Asset Sale or Change
     of Control has occurred or alter the provisions (including the defined
     terms used therein) of Article III of this Indenture or Section 5 of the
     Notes regarding the right of the Company to redeem the Notes as a right, or
     at the Company's option or the provisions (including the deferred terms
     used therein) of Article X in a manner adverse to the Holders; or

               (2)  reduce the percentage in principal amount of the outstanding
     Notes, the consent of whose Holders is required for any such amendment,
     supplemental indenture or wavier provided for in this Indenture; or

                                       87
<PAGE>

               (3)  modify any of the waiver provisions, except to increase any
     required percentage or to provide that certain other provisions of this
     Indenture cannot be modified or waived without the consent of the Holder of
     each outstanding Note affected thereby.

          It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders 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 supplemental indenture or waiver.

          After an amendment, supplement or waiver under this Section 9.2 or
under Section 9.4 hereof becomes effective, it shall bind each Holder.

          In connection with any amendment, supplement or waiver under this
Article IX, the Company may, but shall not be obligated to, offer to any Holder
who consents to such amendment, supplement or waiver, or to all Holders,
consideration for such Holder's consent to such amendment, supplement or waiver.

SECTION 9.3.   COMPLIANCE WITH TIA

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

SECTION 9.4.   REVOCATION AND EFFECT OF CONSENTS

          Until an amendment, waiver or supplement becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Note or portion of a Note that evidences the same debt as the
consenting Holder's Note, even if notation of the consent is not made on any
Note. However, any such Holder or subsequent Holder may revoke the consent as to
his Note or portion of his Note by written notice to the Company or the Person
designated by the Company as the Person to whom consents should be sent if such
revocation is received by the Company or such Person before the date on which
the Trustee receives an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not theretofore revoked
such consent) to the amendment, supplement or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which record date shall be the date so fixed by the
Company notwithstanding the provisions of the TIA. If a record date is fixed,
then notwithstanding the last sentence of the immediately preceding paragraph,
those Persons who were Holders at such record date, and only those Persons (or
their duly designated

                                       88
<PAGE>

proxies), shall be entitled to revoke any consent previously given, whether or
not such Persons continue to be Holders after such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (3) of Section 9.2 hereof, in which case, the amendment, supplement
or waiver shall bind only each Holder of a Note who has consented to it and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note; provided, that any such waiver shall not
impair or affect the right of any Holder to receive payment of principal and
premium of and interest (and Liquidated Damages, if any) on a Note, on or after
the respective dates set for such amounts to become due and payable expressed in
such Note, or to bring suit for the enforcement of any such payment on or after
such respective dates.

SECTION 9.5.   NOTATION ON OR EXCHANGE OF NOTES

          If an amendment, supplement or waiver changes the terms of a Note, the
Trustee may require the Holder of the Note to deliver it to the Trustee or
require the Holder to put an appropriate notation on the Note. The Trustee may
place an appropriate notation on the Note about the changed terms and return it
to the Holder. Alternatively, if the Company or the Trustee so determines, the
Company in exchange for the Note shall issue and the Trustee shall authenticate
a new Note that reflects the changed terms. Any failure to make the appropriate
notation or to issue a new Note shall not affect the validity of such amendment,
supplement or waiver.

SECTION 9.6.   TRUSTEE TO SIGN AMENDMENTS, ETC.

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article IX; provided, that the Trustee may, but
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article IX is
authorized or permitted by this Indenture and that such amendment is the legal,
valid and binding obligation of the Company and the Guarantors party thereto,
enforceable against them in accordance with its terms, subject to customary
exceptions, and complies with the provisions hereof (including Section 9.3).

                                   ARTICLE X

                          RIGHT TO REQUIRE REPURCHASE

SECTION 10.1.  REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF
               CONTROL.

                                       89
<PAGE>

          (a)  In the event that a Change of Control has occurred, each Holder
of Notes will have the right, at such Holder's option, pursuant to an offer
(subject only to conditions required by applicable law, if any) by the Company
(the "Change of Control Offer"), to require the Company to repurchase all or any
part of such Holder's Notes (provided, that the principal amount of such Notes
must be $1,000 or an integral multiple thereof) on a date (the "Change of
Control Purchase Date") that is no later than 60 days after the occurrence of
such Change of Control, at a cash price equal to 101% of the principal amount
thereof (the "Change of Control Purchase Price"), together with accrued and
unpaid interest and Liquidated Damages, if any, to the Change of Control
Purchase Date.

          Notwithstanding the foregoing, the Company will not be required to
make a Change of Control Offer upon a Change of Control if a third party makes
the Change of Control Offer in the manner, at the times and otherwise in
compliance with the requirements set forth herein applicable to a Change of
Control Offer made by the Company, including any requirements to repay in full
all Indebtedness under the Credit Agreement, any Senior Debt or Senior Debt of
any Guarantor or obtains the consents of such lenders to such Change of Control
Offer as set forth in the following paragraph of this Section, and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.

          Notwithstanding anything in this Article X to the contrary, prior to
the commencement of a Change of Control Offer, but in any event within 30 days
following any Change of Control, the Company shall:

               (1)  (A) repay in full, and terminate all commitments under, all
     Indebtedness under the Credit Agreement and all other Senior Debt the terms
     of which require repayment upon a Change of Control or (B) offer to repay
     in full, and terminate all commitments under, all Indebtedness under the
     Credit Agreement and all such other Senior Debt and repay the Indebtedness
     owed to each lender that has accepted such offer in full, or

               (2)  obtain the requisite consents under the Credit Agreement and
     all such other Senior Debt to permit the repurchase of the Notes as
     provided herein.

     The Company's failure to comply with the preceding sentence shall
constitute an Event of Default described in Section 6.1(iii), but without giving
effect to the stated exceptions in such clause.

          (b)  In the event that, pursuant to this Section 10.1, the Company
shall be required to commence a Change of Control Offer, the Company shall
follow the procedures set forth in this Section 10.1 as follows:

               (1)  the Change of Control Offer shall commence within 30 days
     following the occurrence of a Change of Control;

                                       90
<PAGE>

               (2)  the Change of Control Offer shall remain open for 20
     Business Days (the "Change of Control Offer Period") or such other period
     as may be required by applicable law;

               (3)  upon the expiration of the Change of Control Offer Period,
     the Company promptly shall purchase all of the tendered Notes at the Change
     of Control Purchase Price;

               (4)  if the Change of Control Purchase Date is on or after an
     interest payment Record Date and on or before the associated Interest
     Payment Date, any accrued and unpaid interest (and Liquidated Damages, if
     any) due on such Interest Payment Date will be paid to the Person in whose
     name a Note is registered at the close of business on such Record Date on
     the corresponding Interest Payment Date;

               (5)  the Company shall provide the Trustee and the Paying Agent
     with written notice of the Change of Control Offer at least three Business
     Days before the commencement of any Change of Control Offer; and

               (6)  on or before the commencement of any Change of Control
     Offer, the Company or the Trustee (upon the request and at the expense of
     the Company) shall send, by first-class mail, a notice to each of the
     Securityholders, which (to the extent consistent with this Indenture) shall
     govern the terms of the Change of Control Offer and shall state:

                    (A)  that the Change of Control Offer is being
          made pursuant to this Section 10.1 and that all Notes, or
          portions thereof, tendered will be accepted for payment;

                    (B)  the Change of Control Purchase Price
          (including the amount of accrued but unpaid interest (and
          Liquidated Damages, if any)) and the Change of Control
          Purchase Date;

                    (C)  that any Note, or portion thereof, not
          tendered or accepted for payment will continue to accrue
          interest (and Liquidated Damages, if any);

                    (D)  that, unless the Company defaults in
          depositing cash with the Paying Agent in accordance with
          the penultimate paragraph of this Section 10.1, or such
          payment is prevented for any reason, any Note, or portion
          thereof, accepted for payment pursuant to the Change of
          Control Offer shall cease to accrue interest (and
          Liquidated Damages, if any) after the Change of Control
          Purchase Date;

                                       91
<PAGE>

                    (E)  that Holders electing to have a Note, or
          portion thereof, purchased pursuant to a Change of
          Control Offer will be required to surrender the Note,
          with the form entitled "Option of Holder to Elect
          Purchase" on the reverse of the Note completed, to the
          Paying Agent (which may not for purposes of this Section
          10.1, notwithstanding anything in this Indenture to the
          contrary, be the Company or any Affiliate of the Company)
          at the address specified in the notice prior to the
          expiration of the Change of Control Offer;

                    (F)  that Holders will be entitled to withdraw
          their election, in whole or in part, if the Paying Agent
          receives, prior to the expiration of the Change of Control
          Offer, a facsimile transmission or letter setting forth the
          name of the Holder, the principal amount of the Notes the
          Holder is withdrawing and a statement containing a facsimile
          signature and stating that such Holder is withdrawing his
          election to have such principal amount of Notes purchased;

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

                    (H)  a brief description of the events resulting in
          such Change of Control.

          On or before the Change of Control Purchase Date, the Company shall,
to the extent lawful:

               (1)  accept for payment Notes or portions thereof properly
     tendered and not validly withdrawn pursuant to the Change of Control Offer,

               (2)  deposit with the Paying Agent an amount in cash sufficient
     to pay the Change of Control Purchase Price (together with accrued and
     unpaid interest and Liquidated Damages, if any), of all Notes so tendered,
     and

               (3)  deliver to the Trustee the Notes so accepted together with
     an Officers' Certificate listing the Notes or portions thereof being
     purchased by the Company.

The Paying Agent promptly shall pay the Holders of Notes so accepted an amount
equal to the Change of Control Purchase Price (together with accrued and unpaid
interest and Liquidated Damages, if any), and the Trustee promptly will
authenticate and deliver to such Holders a new Note equal in principal amount to
any unpurchased portion of the Note surrendered. Any Notes not so accepted will
be delivered promptly by the Company to the Holder thereof. The Company publicly
will announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Purchase Date.

                                       92
<PAGE>

          Any Change of Control Offer will be made in compliance with all
applicable laws, rules and regulations, including, if applicable, Regulation 14E
under the Exchange Act and the rules thereunder and all other applicable federal
and state securities laws. To the extent that the provisions of any securities
laws or regulations conflict with the provisions of this Article X, the
Company's compliance or compliance by any of the Guarantors with such laws and
regulations shall not in and of itself cause a breach of their obligations under
this Article X.

                                  ARTICLE XI

                                   GUARANTEE

SECTION 11.1.  GUARANTEE

          (a)  Each of the Guarantors shall, jointly and severally, irrevocably
and unconditionally guarantee (the "Guarantee") 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 against the Company
and any other Guarantors of this Indenture, the Notes or the obligations of the
Company under this Indenture or the Notes, that: (x) the principal of and
premium (if any), and interest (and Liquidated Damages, if any) on the Notes
will be paid on a senior subordinated basis in full when due, subject to any
expressly stated applicable grace period, whether at the Maturity Date or
Interest Payment Date, by acceleration, call for redemption, upon a Change of
Control Offer, an Asset Sale Offer or otherwise; (y) all other obligations of
the Company to the Holders or the Trustee under this Indenture or the Notes
(including fees, expenses or other) will be promptly paid in full or performed,
all in accordance with the terms of this Indenture and the Notes; and (z) in
case of any extension of time of payment or renewal of any Notes or any of such
other obligations, they will be paid in full when due or performed in accordance
with the terms of the extension or renewal, whether at maturity, by
acceleration, call for redemption, upon a Change of Control Offer, an Asset Sale
Offer or otherwise. Failing payment when due of any amount so guaranteed for
whatever reason, each Guarantor shall be obligated to pay the same before
failure so to pay becomes an Event of Default.

          If the Company or a Guarantor defaults in the payment of the principal
of, premium, if any, or interest (or Liquidated Damages, if any) on, the Notes
when and as the same shall become due, whether upon maturity, acceleration, call
for redemption, upon a Change of Control Offer, upon an Asset Sale Offer or
otherwise, without the necessity of action by the Trustee or any Holder, each
Guarantor shall be required, jointly and severally, to promptly make such
payment in full.

          The Company shall cause each Subsidiary that is formed or acquired
after the date hereof and each subsidiary that becomes a Subsidiary after the
date hereof, in each case other than Foreign Subsidiaries and Non-Guarantor
Subsidiaries, concurrently upon becoming a Subsidiary, to become a Guarantor
hereunder and execute and deliver to the Trustee a supplemental indenture as
provided pursuant to the terms of this Indenture.

                                       93
<PAGE>

          Notwithstanding anything herein to the contrary, if any of the
Company's Subsidiaries that is not a Guarantor guarantees any of the Company's
other Indebtedness or any other Indebtedness of any of its Subsidiaries, or the
Company or any of its Subsidiaries, individually or collectively, pledges,
directly or indirectly, more than 65% of the Voting Equity Interests of such
Subsidiary to a lender (other than pledges of Equity Interests of Non-Guarantor
Subsidiaries pursuant to the Credit Agreement), then such Subsidiary must become
a Guarantor in accordance with the terms hereof.

          (b)  Each Guarantor hereby agrees to the fullest extent permitted by
applicable law, that its obligations with regard to this Guarantee 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
delays in obtaining or realizing upon or failures to obtain or realize upon
collateral, the recovery of any judgment against the Company, any action to
enforce the same or any other circumstances that might otherwise constitute a
legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby
waives to the fullest extent permitted by applicable law 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 or right to require the prior disposition of the assets of the Company
to meet its obligations, protest, notice and all demands whatsoever and
covenants that this Guarantee will not be discharged except by complete
performance of the obligations contained in the Notes and this Indenture.

          (c)  If any Holder or the Trustee is required by any court or
otherwise to return to either the Company or any Guarantor, or any Custodian or
similar official acting in relation to either the Company or such Guarantor, any
amount paid by either the Company or such Guarantor to the Trustee or such
Holder, this Guarantee, to the extent theretofore discharged, shall be
reinstated in full force and effect. Each Guarantor agrees that it will 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 such
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand,
(i) the maturity of the obligations guaranteed hereby may be accelerated as
provided in Section 6.2 hereof for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration as to the Company of the obligations guaranteed hereby, and (ii) in
the event of any declaration of acceleration of those obligations as provided in
Section 6.2 hereof, those obligations (whether or not due and payable) will
forthwith become due and payable by each of the Guarantors for the purpose of
this Guarantee.

          (d)  It is the intention of each Guarantor and the Company that the
obligations of each Guarantor hereunder shall be in, but not in excess of, the
maximum amount permitted by applicable law. Accordingly, if the obligations in
respect of the Guarantee would be annulled, avoided or subordinated to the
creditors of any Guarantor by a court of competent jurisdiction in a proceeding
actually pending before such court as a result of a determination both that such
Guarantee was made by such Guarantor without fair consideration and, immediately
after giving effect thereto, such Guarantor was insolvent or unable to pay its
debts as they mature or left with an unreasonably small capital, then the
obligations of such Guarantor under such Guarantee shall be reduced by such

                                       94
<PAGE>

court if and to the extent such reduction would result in the avoidance of such
annulment, avoidance or subordination; provided, however, that any reduction
pursuant to this paragraph shall be made in the smallest amount as is strictly
necessary to reach such result. For purposes of this paragraph, "fair
consideration", "insolvency", "unable to pay its debts as they mature",
"unreasonably small capital" and the effective times of reductions, if any,
required by this paragraph shall be determined in accordance with applicable
law.

SECTION 11.2.  EXECUTION AND DELIVERY OF GUARANTEE

          Each Guarantor shall, by virtue of such Guarantor's execution and
delivery of an indenture supplement pursuant to Section 11.1 hereof, be deemed
to have signed on each Note issued hereunder the notation of guarantee set forth
on the form of the Notes attached hereto as Exhibit A to the same extent as if
the signature of such Guarantor appeared on such Note.

          The delivery of any Note by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the guarantee set forth in
Section 11.1 on behalf of each Guarantor. The notation of a guarantee set forth
on any Note shall be null and void and of no further effect with respect to the
guarantee of any Guarantor which, pursuant to Section 11.4, is released from
such Guarantee.

SECTION 11.3.  CERTAIN BANKRUPTCY EVENTS

          Each Guarantor hereby covenants and agrees, to the fullest extent that
it may do so under applicable law, that in the event of the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company, such
Guarantor shall not file (or join in any filing of), or otherwise seek to
participate in the filing of, any motion or request seeking to stay or to
prohibit (even temporarily) execution on the Guarantee and hereby waives and
agrees not to take the benefit of any such stay of execution, whether under
Section 362 or 105 of the United States Bankruptcy Code or otherwise.

SECTION 11.4.  LIMITATION ON MERGER OF SUBSIDIARIES AND RELEASE OF GUARANTORS

          No Guarantor shall consolidate or merge with or into (whether or not
such Guarantor is the surviving Person) another Person unless, subject to the
provisions of the following paragraph and the other provisions of this
Indenture, (1) the Person formed by or surviving any such consolidation or
merger (if other than such Guarantor) assumes all the obligations of such
Guarantor pursuant to a supplemental indenture in form reasonably satisfactory
to the Trustee, pursuant to which such Person shall guarantee, on a senior
subordinated basis, all of such Guarantor's obligations under such Guarantor's
Guarantee on the terms set forth herein; and (2) immediately before and
immediately after giving effect to such transaction on a pro forma basis, no
Default or Event of Default shall have occurred or be continuing. The provisions
of this Section 11.4 shall not apply to the merger of any Guarantors with and
into each other or with or into the Company.

                                       95
<PAGE>

          Upon the sale or disposition (whether by merger, stock purchase, Asset
Sale or otherwise) of a Guarantor (as an entity) to an entity which is not, and
is not required to become, a Guarantor, or the designation of a Subsidiary to
become an Unrestricted Subsidiary, or upon a Guarantor becoming a Non-Guarantor
Subsidiary which transaction is otherwise in compliance with this Indenture
(including, without limitation, the provisions of Section 4.14), such Guarantor
will be deemed released from its obligations under its Guarantee of the Notes
and such Guarantee will terminate; provided, however, that any such termination
shall occur only to the extent that all obligations of such Guarantor under all
of its guarantees of, and under all of its pledges of assets or other security
interests that secure, any of the Company's Indebtedness or any Indebtedness of
any other of the Company's Subsidiaries shall also terminate upon such release,
sale or transfer and none of such Guarantor's Equity Interests are pledged for
the benefit of any holder of any of the Company's Indebtedness or any
Indebtedness of any of the Company's Subsidiaries (other than pledges of Equity
Interests of Non-Guarantor Subsidiaries pursuant to the Credit Agreement).

          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 in accordance with the applicable provisions of this
Indenture, the Trustee shall execute any documents reasonably required to
evidence the release of any Guarantor from its obligations under the Guarantee.

SECTION 11.5.  SUBORDINATION OF GUARANTEES

          The obligations of each Guarantor under its Guarantee pursuant to this
Article XI are subordinated in right of payment to the prior payment in full in
cash of all Senior Debt of such Guarantor on the same basis as the Notes are
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 Notes pursuant to this Indenture, including
Article XII hereof. In the event that the Trustee receives any Guarantor payment
at a time when such payment is prohibited by the foregoing sentence, such
Guarantor payment shall be held for the benefit of, and paid over and delivered
to, the holders of the Senior Debt of such Guarantor remaining unpaid, to the
extent necessary to pay in full all such Senior Debt. In the event that a Holder
receives any Guarantor payment at a time when such payment is prohibited by the
foregoing sentence, such Guarantor payment shall be held for the benefit of, and
paid over and delivered to, the holders of the Senior Debt of such Guarantor
remaining unpaid, to the extent necessary to pay in full all such Senior Debt.

          Each Holder of a Note by its acceptance thereof (a) agrees to and
shall be bound by the provisions of this Section 11.5, (b) authorizes and
directs the Trustee on the Holder's behalf to take such action as may be
necessary and appropriate to effectuate the subordination so provided, and (c)
appoints the Trustee as the Holder's attorney-in-fact for any and all such
purposes.

                                  ARTICLE XII

                                 SUBORDINATION

SECTION 12.1.  NOTES SUBORDINATED TO SENIOR DEBT

          The Company and the Guarantors and each Holder, by its acceptance of
Notes, agree that (a) the payment of the principal of and interest (and
Liquidated Damages, if any) on the Notes and (b) any other payment in respect of
the Notes, including on account of the acquisition or redemption of the Notes by
the Company and the Guarantors (including, without limitation, pursuant to
Section 4.14 and Article X) is subordinated, to the extent and in the manner
provided in this Article XII, to the prior payment in full in cash or Cash
Equivalents of all Senior Debt of the Company and the Guarantors and that these
subordination provisions are for the benefit of the holders of Senior Debt.

          This Article XII shall constitute a continuing offer to all Persons
who, in reliance upon such provisions, become holders of, or continue to hold,
Senior Debt, and such provisions are made for the benefit of the holders of
Senior Debt and such holders are made obligees hereunder and any one or more of
them may enforce such provisions.

SECTION 12.2.  NO PAYMENT ON NOTES IN CERTAIN CIRCUMSTANCES

          (a)  No payment (by set-off or otherwise) shall be made by or on
behalf of the Company or a Guarantor, as applicable, on account of the principal
of, premium, if any, or interest (or Liquidated Damages) on the Notes, or on
account of the redemption provisions of the Notes (including any repurchases of
Notes), for cash or property (other than Junior Securities), (i) upon the
maturity of any Senior Debt of the Company or such Guarantor, as applicable, by
lapse of time, acceleration (unless waived) or otherwise, unless and until all
principal of, premium, if any, and the interest on, and all other amounts owning
in respect of, such Senior Debt are first paid in full in cash or Cash
Equivalents (or such payment is duly provided for) or otherwise to the extent
holders accept satisfaction of amounts due by settlement in other than cash or
Cash Equivalents, or (ii) in the event of default in the payment of any
principal of, premium, if any, or interest on Senior Debt of the Company or such
Guarantor, as applicable, when it becomes due and payable, whether at maturity,
or at a date fixed for prepayment or by declaration or otherwise (a "Payment
Default"), unless and until such Payment Default has been cured or waived or
otherwise has ceased to exist.

          (b)  Upon (i) the happening of an event of default other than a
Payment Default that permits the holders of any Designated Senior Debt to
declare such Designated Senior Debt to be due and payable and (ii) written
notice of such event of default given to the Company and the Trustee by the
holders of such Designated Senior Debt or their representative (a "Payment
Notice"), then, unless and until such event of default has been cured or waived
or otherwise has ceased to exist, no payment (by set-off or otherwise) may be
made by or on behalf of the Company or any Guarantor which is an obligor under
such Designated Senior Debt on account of the principal of, premium, if any, or
interest (or Liquidated Damages, if any) on the Notes, (including any

                                       97
<PAGE>

repurchases of any of the Notes), or on account of the redemption provisions of
the Notes, in any such case, other than payments made with Junior Securities.
Notwithstanding the foregoing, unless the Designated Senior Debt in respect of
which such event of default exists has been declared due and payable in its
entirety within 179 days after the Payment Notice is delivered as set forth
above (the "Payment Blockage Period") (and such declaration has not been
rescinded or waived), at the end of the Payment Blockage Period, the Company and
the Guarantors shall be required, to pay all sums not previously paid to the
Holders of the Notes during the Payment Blockage Period due to the foregoing
prohibitions and to resume all other payments as and when due on the Notes.

          Any number of Payment Notices may be given; provided, however, that
(i) not more than one Payment Notice shall be given within a period of any 360
consecutive days, and (ii) no non-payment default that existed upon the date of
such Payment Notice or the commencement of such Payment Blockage Period (whether
or not such event of default is on the same issue of Designated Senior Debt)
shall be made the basis for the commencement of any other Payment Blockage
Period (for purposes of this provision, any subsequent action, or any subsequent
breach of any financial covenant for a period commencing after the expiration of
such Payment Blockage Period that, in either case, would give rise to a new
event of default, even though it is an event that would also have been a
separate breach pursuant to any provision under which a prior event of default
previously existed, shall constitute a new event of default).

          (c)  In furtherance of the provisions of Section 12.1, in the event
that, notwithstanding the foregoing provisions of this Section 12.2 or Section
12.3, any payment or distribution of assets of the Company or any Guarantor
(other than Junior Securities) shall be received by the Trustee or the Holders
at a time when such payment or distribution is prohibited by the foregoing
provisions of this Section 12.2, such payment or distribution shall be held for
the benefit of the holders of such Senior Debt, and shall be paid or delivered
by the Trustee or such Holders, as the case may be, to the holders of such
Senior Debt remaining unpaid or unprovided for or to their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any of such Senior Debt may have been issued,
ratably according to the aggregate principal amounts remaining unpaid on account
of such Senior Debt held or represented by each, for application to the payment
of all such Senior Debt remaining unpaid, to the extent necessary to pay or to
provide for the payment of all such Senior Debt in full in cash or Cash
Equivalents, or otherwise to the extent holders accept satisfaction of amounts
due by settlement in other than cash or Cash Equivalents after giving effect to
any concurrent payment or distribution to the holders of such Senior Debt.

SECTION 12.3.  NOTES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR DEBT ON
               DISSOLUTION, LIQUIDATION OR REORGANIZATION

          Upon any distribution of assets of the Company or any Guarantor upon
any dissolution, winding up, total or partial liquidation or reorganization of
the Company or a Guarantor, whether voluntary or involuntary, in bankruptcy,
insolvency, receivership or a similar proceeding or upon assignment for the
benefit of creditors or any marshalling of assets or liabilities:

                                       98
<PAGE>

          (a)  the holders of all Senior Debt of the Company or such Guarantor,
as applicable, will first be entitled to receive payment in full in cash or Cash
Equivalents (or have such payment duly provided for) or otherwise to the extent
such holders accept satisfaction of amounts due by settlement in other than cash
or Cash Equivalents before the Holders are entitled to receive any payment on
account of the principal of, premium, if any, and interest (or Liquidated
Damages, if any) on the Notes (other than Junior Securities); and

          (b)  any payment or distribution of assets of the Company or such
Guarantor of any kind or character from any source, whether in cash, property or
securities (other than Junior Securities) to which the Holders or the Trustee on
behalf of the Holders would be entitled (by set-off or otherwise), except for
the subordination provisions contained in this Indenture, will be paid by the
liquidating trustee or agent or other Person making such a payment or
distribution directly to the holders of such Senior Debt or their representative
to the extent necessary to make payment in full (or have such payment duly
provided for) on all such Senior Debt remaining unpaid, after giving effect to
any concurrent payment or distribution to the holders of such Senior Debt.

SECTION 12.4.  SECURITYHOLDERS TO BE SUBROGATED TO RIGHTS OF HOLDERS OF SENIOR
               DEBT

          Subject to the payment in full in cash or Cash Equivalents of all
Senior Debt of the Company or any Guarantor as provided herein, the Holders of
Notes shall be subrogated to the rights of the holders of such Senior Debt to
receive payments or distributions of assets of the Company applicable to the
Senior Debt until all amounts owing on the Notes shall be paid in full, and for
the purpose of such subrogation no such payments or distributions to the holders
of such Senior Debt by or on behalf of the Company or any Guarantor, or by or on
behalf of the Holders by virtue of this Article XII, which otherwise would have
been made to the Holders shall, as between the Company or any Guarantor and the
Holders, be deemed to be payment by the Company or any Guarantor or on account
of such Senior Debt, it being understood that the provisions of this Article XII
are and are intended solely for the purpose of defining the relative rights of
the Holders, on the one hand, and the holders of such Senior Debt, on the other
hand.

SECTION 12.5.  OBLIGATIONS OF THE COMPANY AND THE GUARANTORS UNCONDITIONAL

          Nothing contained in this Article XII or elsewhere in this Indenture
or in the Notes is intended to or shall impair, as between the Company and any
Guarantors and the Holders, the obligation of each such Person, which is
absolute and unconditional, to pay to the Holders the principal of, premium, if
any, and interest (and Liquidated Damages, if any) on the Notes as and when the
same shall become due and payable in accordance with their terms, or is intended
to or shall affect the relative rights of the Holders and creditors of the
Company and the Guarantors other than the holders of the Senior Debt, nor shall
anything herein or therein prevent the Trustee or any Holder from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article XII, of the holders
of Senior Debt in respect of cash, property or securities of the Company and the
Guarantors received upon the exercise of any

                                       99
<PAGE>

such remedy. Notwithstanding anything to the contrary in this Article XII or
elsewhere in this Indenture or in the Notes, upon any distribution of assets of
the Company and the Guarantors referred to in this Article XII, the Trustee,
subject to the provisions of Sections 7.1 and 7.2, and the Holders shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding up, liquidation or
reorganization proceedings are pending, or a certificate of the liquidating
Trustee or agent or other Person making any distribution to the Trustee or to
the Holders for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Debt and other Indebtedness of
the Company or any Guarantor, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XII so long as such court has been apprised of the provisions
of, or the order, decree or certificate makes reference to, the provisions of
this Article XII.

          Nothing in this Article XII shall apply to the claims of, or payments
to, the Trustee under or pursuant to Section 7.7.

SECTION 12.6.  TRUSTEE ENTITLED TO ASSUME PAYMENTS NOT PROHIBITED IN ABSENCE OF
               NOTICE.

          The Trustee shall not at any time be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee unless and until a Trust Officer of the Trustee or any Paying Agent
shall have received, no later than one Business Day prior to such payment
written notice thereof from the Company or from one or more holders of Senior
Debt or from any representative therefor and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of Sections 7.1 and 7.2,
shall be entitled in all respects conclusively to assume that no such fact
exists.

SECTION 12.7.  APPLICATION BY TRUSTEE OF ASSETS DEPOSITED WITH IT

          Amounts deposited in trust with the Trustee pursuant to and in
accordance with Article VIII shall be for the sole benefit of Securityholders
and, to the extent the making of such deposit by the Company shall (i) not be in
contravention of any term or provision of the Credit Agreement and (ii) be
allocated for the payment of the Notes, shall not be subject to the
subordination provisions of this Article XII. Otherwise, any deposit of assets
with the Trustee or the Agent (whether or not in trust) for the payment of
principal of or interest on any Notes shall be subject to the provisions of
Sections 12.1, 12.2, 12.3 and 12.4; provided, that, if prior to one Business Day
preceding the date on which by the terms of this Indenture any such assets may
become distributable for any purpose (including without limitation, the payment
of either principal of or interest on any Note) the Trustee or such Paying Agent
shall not have received with respect to such assets the written notice provided
for in Section 12.6, then the Trustee or such Paying Agent shall have full power
and authority to receive such assets and to apply the same to the purpose for
which they were received, and shall not be affected by any notice to the
contrary which may be received by it on or after such date.

SECTION 12.8.  SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS OF THE
               COMPANY, THE GUARANTORS OR HOLDERS OF SENIOR DEBT

          No right of any present or future holders of any Senior Debt to
enforce the subordination provisions contained in this Article XII shall at any
time in any way be prejudiced or impaired by any act or failure to act on the
part of the Company or any Guarantor or by any act or failure to act, in good
faith, by any such holder, or by any noncompliance by the Company or any
Guarantor with the terms of this Indenture, regardless of any knowledge thereof
which any such holder may have or be otherwise charged with. The holders of
Senior Debt may extend, renew, modify or amend the terms of the Senior Debt or
any security therefor and release, sell or exchange such security and otherwise
deal freely with the Company and the Guarantors, all without affecting the
liabilities and obligations of the parties to this Indenture or the Holders. The
subordination provisions contained in this Indenture are for the benefit of the
holders from time to time of Senior Debt and may not be rescinded, cancelled,
amended or modified in any way other than any amendment or modification that
would not adversely affect the rights of any holder of Senior Debt or any
amendment or modification that is consented to by each holder of Senior Debt
that would be adversely affected thereby. The subordination provisions hereof
shall continue to be effective or be reinstated, as the case may be, if at any
time any payment of any of the Senior Debt is rescinded or must otherwise be
returned by any holder of the Senior Debt upon the insolvency, bankruptcy, or
reorganization of the Company, any Guarantor, or otherwise, all as though such
payment has not been made.

SECTION 12.9.  SECURITYHOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE SUBORDINATION OF
               NOTES.

          Each Holder of the Notes by his acceptance thereof authorizes and
expressly directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination provisions contained in
this Article XII and to protect the rights of the Holders pursuant to this
Indenture, and appoints the Trustee his attorney-in-fact for such purpose,
including, in the event of any dissolution, winding up, liquidation or
reorganization of the Company or any Guarantor (whether in bankruptcy,
insolvency or receivership proceedings or upon an assignment for the benefit of
creditors or any other marshalling of assets and liabilities of the Company or
any Guarantor), the immediate filing of a claim for the unpaid balance of his
Notes in the form required in said proceedings and cause said claim to be
approved. In the event of any liquidation or reorganization of the Company or
any Guarantor in bankruptcy, insolvency, receivership or similar proceeding, if
the Holders of the Notes (or the Trustee on their behalf) have not filed any
claim, proof of claim, or other instrument of similar character necessary to
enforce the obligations of the Company or any Guarantor in respect of the Notes
at least thirty (30) days before the expiration of the time to file the same,
then in such event, but only in such event, the holders of the Senior Debt or a
representative on their behalf may, as an attorney-in-fact for such Holders,
file any claim, proof of claim, or other instrument of similar character on
behalf of such Holders. Nothing herein contained shall be deemed to authorize
the Trustee or the holders of Senior Debt or their representative to authorize
or consent to or accept or adopt on behalf of any Securityholder any plan

                                      101
<PAGE>

of reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee or the holders of
Senior Debt or their representative to vote in respect of the claim of any
Securityholder in any such proceeding.

SECTION 12.10. RIGHT OF TRUSTEE TO HOLD SENIOR DEBT

          The Trustee shall be entitled to all of the rights set forth in this
Article XII in respect of any Senior Debt at any time held by it to the same
extent as any other holder of Senior Debt, and nothing in this Indenture shall
be construed to deprive the Trustee of any of its rights as such holder.

SECTION 12.11. ARTICLE XII NOT TO PREVENT EVENTS OF DEFAULT

          The failure to make a payment on account of principal of, premium, if
any, or interest (or Liquidated Damages, if any) on the Notes by reason of any
provision of this Article XII shall not be construed as preventing the
occurrence of a Default or an Event of Default under Section 6.1 or in any way
limit the rights of the Trustee or any Holder to pursue any other rights or
remedies with respect to the Notes.

SECTION 12.12. NO FIDUCIARY DUTY OF TRUSTEE TO HOLDERS OF SENIOR DEBT

          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 (other than
for its willful misconduct or negligence) if it shall in good faith mistakenly
pay over or distribute to the Holders of Notes or the Company, any Guarantor or
any other Person, cash, property or securities to which any holders of Senior
Debt shall be entitled by virtue of this Article XII or otherwise. Nothing in
this Section 12.12 shall affect the obligation of any other such Person to hold
such payment for the benefit of, and to pay such payment over to, the holders of
Senior Debt or their representative. In the event of any conflict between the
fiduciary duty of the Trustee to the Holders of Notes and to the holders of
Senior Debt, the Trustee is expressly authorized to resolve such conflict in
favor of the Holders.

                                  ARTICLE XIII

                                  MISCELLANEOUS

SECTION 13.1.  TIA CONTROLS

          If any provision of this Indenture limits, qualifies, or conflicts
with the duties imposed by operation of the TIA, the imposed duties, upon
qualification of this Indenture under the TIA, shall control.

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

          1.   Interest. DaVita Inc., a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Note at 9 1/4% per
annum from April 11, 2001 until maturity and shall pay the Liquidated Damages,
if any, payable pursuant to Section 5 of the Registration Rights Agreement
referred to below. The Company will pay interest and Liquidated Damages, if any,
semi-annually in arrears on April 15 and October 15 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 provided for or, if no interest has been
paid, from the Issue Date; provided, that if there is no existing Default in the
payment of interest, and if this Note is authenticated between a Record Date
(defined below) 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 October
15, 2001. The Company shall pay interest on overdue principal and premium, if
any, from time to time on demand at the rate then in effect; it shall pay
interest on overdue installments of interest and Liquidated Damages, if any,
(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 Liquidated Damages, if any, to the Persons who
are registered Holders of Notes at the close of business on the April 1 or
October 1 next preceding the Interest Payment Date (each a "Record Date"), even
if such Notes are cancelled after such Record Date and on or before such
Interest Payment Date, except as provided in Section 2.12 of the Indenture (as
defined below) with respect to defaulted interest. The Notes will be payable as
to principal, premium, interest and Liquidated Damages, if any, at the office or
agency of the Company maintained in the Borough of Manhattan, the City and State
of New York for such purpose, or, at the option of the Company, payment of
interest and Liquidated Damages, if any, 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 to an account
within the United States will be required with respect to principal of and
interest, premium and Liquidated Damages, if any, on all Global Notes. 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, U.S. Trust Company of
Texas, 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 April 11, 2001 ("Indenture") among the Company, the Guarantors party
thereto and the

                                      A-5
<PAGE>

Trustee. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code ss.ss. 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.

               5.   Optional Redemption.

               (a)  Except as set forth in clause (b) of this Section 5, the
Company shall not have the option to redeem the Notes pursuant to this Section 5
prior to April 15, 2006. The Notes will be redeemable for cash at the option of
the Company, in whole or in part, at any time on or after April 15, 2006, upon
not less than 30 days nor more than 60 days prior notice mailed by first class
mail to each Holder at its last registered address, at the following redemption
prices (expressed as percentages of the principal amount) if redeemed during the
12-month period commencing April 15, of the years indicated below, in each case
(subject to the right of Holders of record on a Record Date to receive the
corresponding interest due (and the corresponding Liquidated Damages, if any) on
the corresponding Interest Payment Date that is on or prior to such Redemption
Date) together with accrued and unpaid interest and Liquidated Damages, if any,
thereon to the Redemption Date:

          Year                                             Percentage
          ----                                             ----------
          2006............................................  104.625%
          2007............................................  103.083%
          2008............................................  101.542%
          2009 and thereafter.............................  100.000%

               (b)  Notwithstanding the provisions of clause (a) of this Section
5, at any time on or prior to April 15, 2004, upon any Public Equity Offering,
up to 35% of the aggregate principal amount of the Notes issued under the
Indenture may be redeemed at the option of the Company within 90 days of such
Public Equity Offering, on not less than 30 days, but not more than 60 days,
prior notice to each Holder of the Notes to be redeemed, with cash from the Net
Cash Proceeds of such Public Equity Offering, at a redemption price equal to
109.25% of the principal amount thereof (subject to the right of Holders of
record on a Record Date to receive the corresponding interest (and the
corresponding Liquidated Damages, if any) due on the Interest Payment Date that
is on or prior to such Redemption Date) together with accrued and unpaid
interest and Liquidated Damages, if any, thereon to the Redemption Date;
provided, that immediately following such redemption not less than 65% of the
aggregate principal amount of the Notes originally issued pursuant to the
Indenture remain outstanding.

               (c)  Notice of redemption will be mailed by first class mail at
least 30 days but not more than 60 days prior to 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 integral
multiples of $1,000, unless all of the Notes held by a

                                      A-6
<PAGE>

Holder are to be redeemed. On and after the Redemption Date interest (and
Liquidated Damages, if any) ceases to accrue on Notes or portions thereof called
for redemption unless the Company defaults in such payments due on the
Redemption Date.

          6.   Mandatory Redemption. The Company shall not be required to make
mandatory redemption payments with respect to the Notes. The Notes shall not
have the benefit of any sinking fund.

          7.   Offers to Purchase.

          (a)  Change of Control. In the event that a Change of Control has
occurred, each Holder of Notes will have the right, at such Holder's option,
pursuant to an offer (subject only to conditions required by applicable law, if
any) by the Company (the "Change of Control Offer"), to require the Company to
repurchase all or any part of such Holder's Notes (provided, that the principal
amount of such Notes must be $1,000 or an integral multiple thereof) on a date
(the "Change of Control Purchase Date") that is no later than 60 days after the
occurrence of such Change of Control, at a cash price equal to 101% of the
principal amount thereof (the "Change of Control Purchase Price"), together with
accrued and unpaid interest and Liquidated Damages, if any, to the Change of
Control Purchase Date. The Change of Control Offer shall be made within 30 days
following a Change of Control and shall remain open for 20 Business Days
following its commencement (the "Change of Control Offer Period"). Upon
expiration of the Change of Control Offer Period, the Company promptly shall
purchase all Notes properly tendered in response to the Change of Control Offer.

          Prior to the commencement of a Change of Control Offer, but in any
event within 30 days following any Change of Control, the Company shall (i)(a)
repay in full, and terminate all commitments under, all Indebtedness under the
Credit Agreement and all other Senior Debt, the terms of which require repayment
upon a Change of Control or (b) offer to repay in full, and terminate all
commitments under, all Indebtedness under the Credit Agreement and all such
other Senior Debt and repay the Indebtedness owed to each lender that has
accepted such offer in full or (ii) obtain the requisite consents under the
Credit Agreement and all such other Senior Debt to permit the repurchase of the
Notes as provided herein. The Company's failure to comply with the preceding
sentence shall constitute an Event of Default described in Section 6.1(iii), but
without giving effect to the stated exceptions in such clause.

          On or before the Change of Control Purchase Date, the Company shall,
to the extent lawful, (i) accept for payment Notes or portions thereof properly
tendered and not validly withdrawn pursuant to the Change of Control Offer, (ii)
deposit with the Paying Agent an amount in cash sufficient to pay the Change of
Control Purchase Price (together with accrued and unpaid interest and Liquidated
Damages, if any), of all Notes so tendered and (iii) deliver to the Trustee the
Notes so accepted together with an Officers' Certificate listing the Notes or
portions thereof being purchased by the Company. The Paying Agent

                                      A-7
<PAGE>

promptly shall pay the Holders of Notes so accepted an amount equal to the
Change of Control Purchase Price (together with accrued and unpaid interest and
Liquidated Damages, if any), and the Trustee promptly will authenticate and
deliver to such Holders a new Note equal in principal amount to any unpurchased
portion of the Note surrendered. Any Notes not so accepted will be delivered
promptly by the Company to the Holder thereof. The Company publicly will
announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Purchase Date.

          (b)  Asset Sale. The Company and the Guarantors shall not, and neither
the Company nor the Guarantors shall permit any of their respective Subsidiaries
to, in one or a series of related transactions, convey, sell, lease, transfer,
assign or otherwise dispose of, directly or indirectly, any of their property,
business or assets, including by merger or consolidation (in the case of a
Guarantor or a Subsidiary of the Company), and including any sale or other
transfer or issuance of any Equity Interests of any Subsidiary or Unrestricted
Subsidiary of the Company, whether by the Company or one of its Subsidiaries or
Unrestricted Subsidiaries or through the issuance, sale or transfer of Equity
Interests by a Subsidiary or Unrestricted Subsidiary of the Company, and
including any sale and leaseback transaction (any of the foregoing, an "Asset
Sale"), unless (l)(a) the Net Cash Proceeds therefrom (the "Asset Sale Offer
Amount") are applied within 365 days after the date of such Asset Sale, to the
extent not applied in accordance with paragraph (b) below, to the (i) optional
redemption of the Notes in accordance with the terms of the Indenture and other
Indebtedness of the Company ranking on a parity with the Notes and with similar
provisions requiring the Company to redeem such Indebtedness with the proceeds
from such Asset Sale, pro rata in proportion to the respective principal amounts
(or accreted values in the case of Indebtedness issued with an original issue
discount) of the Notes and such other Indebtedness then outstanding or (ii)
repurchase of the Notes and such other Indebtedness ranking on a parity with the
Notes and with similar provisions requiring the Company to make an offer to
purchase such Indebtedness with the proceeds from such Asset Sale pursuant to a
cash offer (subject only to conditions required by applicable law, if any) (pro
rata in proportion to the respective principal amounts (or accreted values in
the case of Indebtedness issued with an original issue discount) of the Notes
and such other Indebtedness then outstanding) (the "Asset Sale Offer") at a
purchase price of 100% of principal amount (or accreted value in the case of
Indebtedness issued with an original issue discount) (the "Asset Sale Offer
Price") together with accrued and unpaid interest and Liquidated Damages, if
any, to the date of payment, made within 335 days of such Asset Sale or (b)
within 365 days following such Asset Sale, the Asset Sale Offer Amount is (i)
invested in assets and property (other than notes, bonds, obligations and
securities, except in connection with the acquisition of a Wholly Owned
Subsidiary that immediately becomes a Guarantor in a Related Business) which
will constitute or be a part of a Related Business of the Company or such
Subsidiary (if it continues to be a Subsidiary) immediately following such
transaction or (ii) used to retire Senior Debt and to permanently reduce the
amount of such Senior Debt outstanding on the Issue Date or permitted pursuant
to paragraphs (b) and (c) of Section 4.11 of the Indenture (including that in
the case of a revolver or similar arrangement that makes credit available, such
commitment is so permanently reduced by

                                      A-8
<PAGE>

such amount); provided, however, that with respect to any Asset Sale occurring
during 2001, the Asset Sale Offer Amount received therefrom may be applied as
provided in (a) or (b) above at any time prior to December 31, 2002, and any
Asset Sale Offer made in accordance with (a)(ii) above may be made at any time
prior to December 1, 2002, (2) at least 75% of the total consideration for such
Asset Sale or series of related Asset Sales consists of cash or Cash
Equivalents, provided, that up to one-third of such 75% may consist of notes or
other obligations received by the Company or such Subsidiary from such
transferee that are converted by the Company or such Subsidiary into cash (to
the extent of the cash received) within 365 days after receipt, which shall
constitute Net Cash Proceeds attributable to the original Asset Sale for which
such notes or other obligations were received, and provided further that any
Indebtedness of the Company or any Subsidiary (as shown on the Company's or such
Subsidiary's most recent balance sheet), other than Subordinated Indebtedness,
that is assumed by the transferee of any such assets shall constitute cash for
purposes hereof, so long as the Company and all of its Subsidiaries are fully
and unconditionally released therefrom, and (3) the Company or such Subsidiary,
as applicable, receives fair market value for such Asset Sale, such
determination to be made in good faith by the Board of Directors of the Company
for Asset Sales exceeding $25,000,000. Pending the final application of any Net
Cash Proceeds, the Company may temporarily reduce revolving credit borrowings or
otherwise invest the Net Cash Proceeds in any manner that is not prohibited by
the Indenture.

          An acquisition of Notes pursuant to an Asset Sale Offer may be
deferred until the accumulated Net Cash Proceeds from Asset Sales not applied to
the uses and in the time periods set forth in 1(a)(i) or 1(b) above (the "Excess
Proceeds") exceeds $10,000,000 and that each Asset Sale Offer shall remain open
for at least 20 Business Days following its commencement (the "Asset Sale Offer
Period"). Upon expiration of the Asset Sale Offer Period, the Company shall
apply the Asset Sale Offer Amount plus an amount equal to accrued and unpaid
interest and Liquidated Damages, if any, to the purchase of all Indebtedness
properly tendered in accordance with the provisions hereof (on a pro rata basis
if the Asset Sale Offer Amount is insufficient to purchase all Indebtedness so

<PAGE>

Guarantors agree, and each Holder by accepting a Note consents and agrees, to
the subordination provided in the Indenture and authorizes the Trustee to give
it effect.

          13.  Trustee Dealings with Company. The Trustee, in its individual or

services for the Company or its Affiliates, and may otherwise deal with the

          14.  No Recourse Against Others. No direct or indirect stockholder,
partner, member, employee, manager, officer or director, as such, past, present
or future, of the Company or any Guarantor, or any successor entity, shall have

Guarantors under the Notes or the Indenture solely by reason of his or its
status as such stockholder, partner, member, employee, manager, officer or
director; provided, that this Section 14 shall in no way limit the obligation of

Registration Rights Agreement dated as of the date of the Indenture, among the
Company, the Guarantors and the Initial Purchasers (the "Registration Rights
Agreement").

          18.  CUSIP Numbers. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon, and any such redemption shall not
be affected by any defect in or omission of such numbers.

Company to the Holders or the Trustee under the Indenture or under the Notes
(including fees, expenses or other) will be promptly paid in full or performed,
all in accordance with the terms of the Indenture and the Notes; and (c) in case
of any extension of time of payment or renewal of any Notes or any of such other
obligations, the same will be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at maturity, by

Sale Offer or otherwise. The obligations of each Guarantor under its Guarantee
are subordinated in right of payment to the prior payment in full of all
obligations in respect of Senior Debt of such Guarantor as set forth in Section
11.5 and Article XII of the Indenture and shall cease to apply, and shall be
null and void, with respect to any Guarantor who, pursuant to Article XI of the
Indenture, is released from its Guarantee or whose Guarantee otherwise ceases to
be applicable pursuant to the terms of the Indenture.

          When a successor assumes all the obligations of its predecessor under
the Notes and the Indenture, the predecessor will be released from those
obligations.

Ladies and Gentlemen:

               Reference is hereby made to the Indenture, dated as of April 11,

Guarantors party thereto and U.S. Trust Company of Texas, National Association,

meanings given to them in the Indenture.

               In connection with our proposed purchase of $____________
aggregate principal amount of: (a) a beneficial interest in a Global Note, or
(b) a Definitive Note, we confirm that:

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

               2.   We understand that the offer and sale of the Notes have not
been registered under the Securities Act, and that the Notes and any interest
therein may not be

                                      D-1
<PAGE>

offered or sold except as permitted in the following sentence. We agree, on our
own behalf and on behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell the Notes or any interest therein, we will do so
only (1) in the United States to a person whom the seller reasonably believes is
a "qualified institutional buyer" (as defined in Rule 144A under the Securities
Act) in a transaction meeting the requirements of Rule 144A, (2) outside the
United States in an offshore transaction in accordance with Rule 904 under the
Securities Act, (3) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 thereunder (if available) or (4) pursuant to
an effective registration statement under the Securities Act, in each of cases
(1) through (4) in accordance with any applicable securities laws of any state
of the United States, and we further agree to notify any purchaser of the Notes
from us of the resale restrictions referred to above.

               3.   We understand that, on any proposed resale of the Notes or
beneficial interest therein, we will be required to furnish to you and the
Company such certifications, legal opinions and other information as you and the
Company may reasonably require to confirm that the proposed sale complies with
the foregoing restrictions. We further understand that the Notes purchased by us
will bear a legend to the foregoing effect. We further understand that any
subsequent transfer by us of the Notes or beneficial interest therein acquired
by us must be effected through one of the Initial Purchasers.

               4.   We are an institutional "accredited investor" (as defined in
Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and
have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Notes, and
we and any accounts for which we are acting are each able to bear the economic
risk of our or its investment.

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

SECTION 2.  HOLDERS

          A Person is deemed to be a holder of Transfer Restricted Securities
(each, a "Holder") whenever such Person owns Transfer Restricted Securities.
          ------

SECTION 3.  REGISTERED EXCHANGE OFFER

          (a)  Unless the Exchange Offer shall not be permitted by applicable
federal law (after the procedures set forth in Section 6(a)(i) below have been
complied with), the Company and the Guarantors shall (i) cause the Exchange
Offer Registration Statement to be filed with the Commission as soon as
practicable after the Closing Date, but in no event later than 90 days after the
Closing Date (such 90th day being the "Filing Deadline"), (ii) use its best
                                       ---------------
efforts to cause such Exchange Offer Registration Statement to become effective
at the earliest possible time, but in no event later than 180 days after the
Closing Date (such 180th day being the "Effectiveness Deadline"), (iii) in
                                        ----------------------
connection with the foregoing, (A) file all pre-effective amendments to such
Exchange Offer Registration Statement as may be necessary in order to cause it
to become effective, (B) file, if applicable, a post-effective amendment to such
Exchange Offer Registration Statement pursuant to Rule 430A under the Act and
(C) cause all necessary filings, if any, in connection with the registration and
qualification of the Series B Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and Consummate the Exchange Offer.  The Exchange Offer shall be on the
appropriate form permitting (i) registration of the Series B Notes to be offered
in exchange for the Series A Notes that are Transfer Restricted Securities and
(ii) resales of Series B Notes by Broker-Dealers that tendered into the Exchange
Offer Series A Notes that such Broker-Dealer acquired for its own account as a
result of market making activities or other trading activities (other than
Series A Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

          (b)  The Company and the Guarantors shall use their respective best
efforts to cause the Exchange Offer Registration Statement to be effective
continuously, and shall keep the Exchange Offer open for a period of not less
than the minimum period required under applicable federal and state securities
laws to Consummate the Exchange Offer; provided, however, that in no event shall
such period be less than 20 Business Days.  The Company and the Guarantors shall
cause the Exchange Offer to comply with all applicable federal and state
securities laws.  No securities other than the Series B Notes shall be included
in the Exchange Offer Registration Statement.  The Company and the Guarantors
shall use their respective

                                       4
<PAGE>

best efforts to cause the Exchange Offer to be Consummated on the earliest
practicable date after the Exchange Offer Registration Statement has become
effective, but in no event later than 30 business days thereafter (such 30/th/
day being the "Consummation Deadline").
               ---------------------

          (c)  The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Series A Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer.  Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement.  See the Shearman & Sterling no-action letter (available
July 2, 1993).

          Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Series B
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement.  To the extent necessary to ensure that the prospectus
contained in the Exchange Offer Registration Statement is available for sales of
Series B Notes by Broker-Dealers, the Company and the Guarantors agree to use
their respective best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Section 6(a) and (c) hereof and in conformity with
the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
one year from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto.  The Company and the Guarantors shall provide
sufficient copies of the latest version of such Prospectus to such Broker-
Dealers, promptly upon request, and in no event later than one day after such
request, at any time during such period.

                                       5

SECTION 4.  SHELF REGISTRATION

          (a)  Shelf Registration.  If (i) the Exchange Offer is not permitted
               ------------------
by applicable law (after the Company and the Guarantors have complied with the
procedures set forth in Section 6(a)(i) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 Business Days following
the Consummation Deadline that (A) such Holder was prohibited by law or
Commission policy from participating in the Exchange Offer or (B) such Holder
may not resell the Series B Notes acquired by it in the Exchange Offer to the
public without delivering a prospectus and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder or (C) such Holder is a Broker-Dealer and holds Series A
Notes acquired directly from the Company or any of its Affiliates, then the
Company and the Guarantors shall:

          (x)  cause to be filed, on or prior to 30 days after the earlier of
(i) the date on which the Company determines that the Exchange Offer
Registration Statement cannot be filed as a result of clause (a)(i) above and
(ii) the date on which the Company receives the notice specified in clause
(a)(ii) above, (such earlier date, the "Filing Deadline"), a shelf registration
                                        ---------------
statement pursuant to Rule 415 under the Act (which may be an amendment to the
Exchange Offer Registration Statement (the "Shelf Registration Statement")),
                                            ----------------------------
relating to all Transfer Restricted Securities, and

          (y)  shall use their respective best efforts to cause such Shelf
Registration Statement to become effective on or prior to 60 days after the
Filing Deadline for the Shelf Registration Statement (such 60th day the
"Effectiveness Deadline").
 ----------------------

          If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable federal law (i.e.,
clause (a)(i) above), then the filing of the Exchange Offer Registration
Statement shall be deemed to satisfy the requirements of clause (x) above;
provided that, in such event, the Company shall remain obligated to meet the
Effectiveness Deadline set forth in clause (y).

          To the extent necessary to ensure that the Shelf Registration
Statement is available for sales of Transfer Restricted Securities by the
Holders thereof entitled to the benefit of this Section 4(a) and the other
securities required to be registered therein pursuant to Section 6(b)(ii)
hereof, the Company and the Guarantors shall use their respective best efforts
to keep any Shelf Registration Statement required by this Section 4(a)
continuously effective, supplemented, amended and

                                       6
<PAGE>

current as required by and subject to the provisions of Sections 6(b) and (c)
hereof and in conformity with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period of at least two years (as extended pursuant to Section
6(c)(i)) following the Closing Date, or such shorter period as will terminate on
the earlier of the date on which (1) all Transfer Restricted Securities covered
by such Shelf Registration Statement have been sold pursuant thereto or (2)
there cease to be outstanding any Transfer Restricted Securities.

          (b)  Provision by Holders of Certain Information in Connection with
               --------------------------------------------------------------
the Shelf Registration Statement.  No Holder of Transfer Restricted Securities
--------------------------------
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein.  No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information.  Each selling Holder agrees to promptly furnish additional
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

SECTION 5.  LIQUIDATED DAMAGES

          If (i) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (ii)
any such Registration Statement has not been declared effective by the
Commission on or prior to the applicable Effectiveness Deadline, (iii) the
Exchange Offer has not been Consummated on or prior to the Consummation Deadline
or (iv) any Registration Statement required by this Agreement is filed and
declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within two days by a
post-effective amendment to such Registration Statement that cures such failure
and that is itself declared effective within five days of filing such post-
effective amendment to such Registration Statement (each such event referred to
in clauses (i) through (iv), a "Registration Default"), then the Company and the
                                --------------------
Guarantors hereby jointly and severally agree to pay to each Holder of Transfer
Restricted Securities affected thereby liquidated damages in an amount equal to
$.05 per week per $1,000 in principal amount of Transfer Restricted Securities
held by such Holder for each week or portion thereof that the Registration
Default continues for the first 90-day period immediately following the
occurrence of

                                       7
<PAGE>

such Registration Default. The amount of the liquidated damages shall increase
by an additional $.05 per week per $1,000 in principal amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $.25 per week per $1,000 in principal amount of Transfer Restricted
Securities; provided that the Company and the Guarantors shall in no event be
required to pay liquidated damages for more than one Registration Default at any
given time. Notwithstanding anything to the contrary set forth herein, (1) upon
filing of the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement), in the case of (i) above, (2) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of (ii) above, (3)
upon Consummation of the Exchange Offer, in the case of (iii) above, or (4) upon
the filing of a post-effective amendment to the Registration Statement or an
additional Registration Statement that causes the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement) to again be
declared effective or made usable in the case of (iv) above, the liquidated
damages payable with respect to the Transfer Restricted Securities as a result
of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

          All accrued liquidated damages shall be paid to the Holders entitled
thereto, in the manner provided for the payment of interest in the Indenture, on
each Interest Payment Date, as more fully set forth in the Indenture and the
Notes.  Notwithstanding the fact that any securities for which liquidated
damages are due cease to be Transfer Restricted Securities, all obligations of
the Company and the Guarantors to pay liquidated damages with respect to
securities shall survive until such time as such obligations with respect to
such securities shall have been satisfied in full.  Following the cure of all
Registration Defaults relating to any Transfer Restricted Securities, the
accrual of Liquidated Damages with respect to such Transfer Restricted
Securities will cease.  Each obligation to pay Liquidated Damages shall be
deemed to commence accruing on the date of the applicable Registration Default
and to cease accruing when all Registration Defaults have been cured.  In no
event shall the Company pay Liquidated Damages in excess of the applicable
maximum weekly amount set forth above regardless of whether one or multiple
Registration Defaults exist.

SECTION 6.  REGISTRATION PROCEDURES

          (a)  Exchange Offer Registration Statement.  In connection with the
               -------------------------------------
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Series B Notes by
Broker-Dealers

                                       8
<PAGE>

that tendered in the Exchange Offer Series A Notes that such Broker-Dealer
acquired for its own account as a result of its market making activities or
other trading activities (other than Series A Notes acquired directly from the
Company or any of its Affiliates) being sold in accordance with the intended
method or methods of distribution thereof, and (z) comply with all of the
following provisions:

               (i)   If, following the date hereof there has been announced a
change in Commission policy with respect to exchange offers such as the Exchange
Offer, that in the reasonable opinion of counsel to the Company raises a
substantial question as to whether the Exchange Offer is permitted by applicable
federal law, the Company and the Guarantors hereby agree to seek a no-action
letter or other favorable decision from the Commission allowing the Company and
the Guarantors to Consummate an Exchange Offer for such Transfer Restricted
Securities. The Company and the Guarantors hereby agree to pursue the issuance
of such a decision to the Commission staff level. In connection with the
foregoing, the Company and the Guarantors hereby agree to take all such other
actions as may be requested by the Commission or otherwise required in
connection with the issuance of such decision, including without limitation (A)
participating in telephonic conferences with the Commission, (B) delivering to
the Commission staff an analysis prepared by counsel to the Company setting
forth the legal bases, if any, upon which such counsel has concluded that such
an Exchange Offer should be permitted and (C) diligently pursuing a resolution
(which need not be favorable) by the Commission staff.

               (ii)  As a condition to its participation in the Exchange Offer,
each Holder of Transfer Restricted Securities (including, without limitation,
any Holder who is a Broker Dealer) shall furnish, upon the request of the
Company, prior to the Consummation of the Exchange Offer, a written
representation to the Company and the Guarantors (which may be contained in the
letter of transmittal contemplated by the Exchange Offer Registration Statement)
to the effect that (A) it is not an Affiliate of the Company, (B) it is not
engaged in, and does not intend to engage in, and has no arrangement or
understanding with any person to participate in, a distribution of the Series B
Notes to be issued in the Exchange Offer and (C) it is acquiring the Series B
Notes in its ordinary course of business. As a condition to its participation in
the Exchange Offer each Holder using the Exchange Offer to participate in a
distribution of the Series B Notes shall acknowledge and agree that, if the
resales are of Series B Notes obtained by such Holder in exchange for Series A
Notes acquired directly from the Company or an Affiliate thereof, it (1) could
not, under Commission policy as in effect on the date of this Agreement, rely on
the position of the Commission enunciated in Morgan Stanley and Co., Inc.
                                             ----------------------------
(available June 5, 1991) and Exxon Capital Holdings Corporation (available May
                             ----------------------------------
13, 1988), as interpreted in the Commission's letter to Shearman & Sterling
                                                        -------------------

and similar no-action letters (including, if applicable, any no-action letter
obtained pursuant to clause (i) above), and (2) must comply with the
registration and prospectus delivery requirements of the Act in connection with
a secondary resale transaction and that such a secondary resale transaction must
be covered by an effective registration statement containing the selling
security holder information required by Item 507 or 508, as applicable, of
Regulation S-K.

               (iii) Prior to effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors shall provide a supplemental letter to
the Commission (A) stating that the Company and the Guarantors are registering
the Exchange Offer in reliance on the position of the Commission enunciated in
Exxon Capital Holdings Corporation (available May 13, 1988), Morgan Stanley and
----------------------------------                           ------------------
Co., Inc. (available June 5, 1991) as interpreted in the Commission's letter to
---------
Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action letter
-------------------
obtained pursuant to clause (i) above, (B) including a representation that
neither the Company nor any Guarantor has entered into any arrangement or
understanding with any Person to distribute the Series B Notes to be received in
the Exchange Offer and that, to the best of the Company's and each Guarantor's
information and belief, each Holder participating in the Exchange Offer is
acquiring the Series B Notes in its ordinary course of business and has no
arrangement or understanding with any Person to participate in the distribution
of the Series B Notes received in the Exchange Offer and (C) any other
undertaking or representation required by the Commission as set forth in any no-
action letter obtained pursuant to clause (i) above, if applicable.

          (b)  Shelf Registration Statement.   In connection with the Shelf
               ----------------------------
Registration Statement, the Company and the Guarantors shall:

          (i)  comply with all the provisions of Section 6(c) below and use
their respective best efforts to effect such registration to permit the sale of
the Transfer Restricted Securities being sold in accordance with the intended
method or methods of distribution thereof (as indicated in the information
furnished to the Company pursuant to Section 4(b) hereof), and pursuant thereto
the Company and the Guarantors will prepare and file with the Commission a
Registration Statement relating to the registration on any appropriate form
under the Act, which form shall be available for the sale of the Transfer
Restricted Securities in accordance with the intended method or methods of
distribution thereof within the time periods and otherwise in accordance with
the provisions hereof.

          (ii) issue, upon the request of any Holder or purchaser of Series A
Notes covered by any Shelf Registration Statement contemplated by this
Agreement, Series B Notes having an aggregate principal amount equal to the
aggregate principal

                                       10
<PAGE>

     amount of Series A Notes sold pursuant to the Shelf Registration Statement
     and surrendered to the Company for cancellation; the Company shall register
     Series B Notes on the Shelf Registration Statement for this purpose and
     issue the Series B Notes to the purchaser(s) of securities subject to the
     Shelf Registration Statement in the names as such purchaser(s) shall
     designate.

          (c)  General Provisions. In connection with any Registration
               ------------------
     Statement and any related Prospectus required by this Agreement, the
     Company and the Guarantors shall:

               (i)    use their respective best efforts to keep such
     Registration Statement continuously effective and provide all requisite
     financial statements for the period specified in Section 3 or 4 of this
     Agreement, as applicable. Upon the occurrence of any event that would cause
     any such Registration Statement or the Prospectus contained therein (A) to
     contain an untrue statement of material fact or omit to state any material
     fact necessary to make the statements therein not misleading or (B) not to
     be effective and usable for resale of Transfer Restricted Securities during
     the period required by this Agreement, the Company and the Guarantors shall
     file promptly an appropriate amendment to such Registration Statement
     curing such defect, and, if Commission review is required, use their
     respective best efforts to cause such amendment to be declared effective as
     soon as practicable.

               (ii)   prepare and file with the Commission such amendments and
     post-effective amendments to the applicable Registration Statement as may
     be necessary to keep such Registration Statement effective for the
     applicable period set forth in Section 3 or 4 hereof, as the case may be;
     cause the Prospectus to be supplemented by any required Prospectus
     supplement, and as so supplemented to be filed pursuant to Rule 424 under
     the Act, and to comply fully with Rules 424, 430A and 462, as applicable,
     under the Act in a timely manner; and comply with the provisions of the Act
     with respect to the disposition of all securities covered by such
     Registration Statement during the applicable period in accordance with the
     intended method or methods of distribution by the sellers thereof set forth
     in such Registration Statement or supplement to the Prospectus;

               (iii)  advise each Holder promptly and, if requested by such
     Holder, confirm such advice in writing, (A) when the Prospectus or any
     Prospectus supplement or post-effective amendment has been filed, and, with
     respect to any applicable Registration Statement or any post-effective
     amendment thereto, when the same has become effective, (B) of any request
     by the Commission for amendments to the Registration Statement or
     amendments or supplements to the Prospectus or for additional information
     relating thereto, (C) of the issuance by the Commission of any

                                       11
<PAGE>

     stop order suspending the effectiveness of the Registration Statement under
     the Act or of the suspension by any state securities commission of the
     qualification of the Transfer Restricted Securities for offering or sale in
     any jurisdiction, or the initiation of any proceeding for any of the
     preceding purposes, (D) of the existence of any fact or the happening of
     any event that makes any statement of a material fact made in the
     Registration Statement, the Prospectus, any amendment or supplement thereto
     or any document incorporated by reference therein untrue, or that requires
     the making of any additions to or changes in the Registration Statement in
     order to make the statements therein not misleading, or that requires the
     making of any additions to or changes in the Prospectus in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading. If at any time the Commission shall issue any
     stop order suspending the effectiveness of the Registration Statement, or
     any state securities commission or other regulatory authority shall issue
     an order suspending the qualification or exemption from qualification of
     the Transfer Restricted Securities under state securities or Blue Sky laws,
     the Company and the Guarantors shall use their respective best efforts to
     obtain the withdrawal or lifting of such order at the earliest possible
     time;

                    (iv)   subject to Section 6(c)(i), if any fact or event
     contemplated by Section 6(c)(iii)(D) above shall exist or have occurred,
     prepare a supplement or post-effective amendment to the Registration
     Statement or related Prospectus or any document incorporated therein by
     reference or file any other required document so that, as thereafter
     delivered to the purchasers of Transfer Restricted Securities, the
     Prospectus will not contain an untrue statement of a material fact or omit
     to state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

                    (v)    furnish to each Holder in connection with such
     exchange or sale, if any, before filing with the Commission, copies of any
     Registration Statement or any Prospectus included therein or any amendments
     or supplements to any such Registration Statement or Prospectus (including
     all documents incorporated by reference after the initial filing of such
     Registration Statement), which documents will be subject to the review and
     comment of such Holders in connection with such sale, if any, for a period
     of at least five Business Days prior to the initial filing of a
     Registration Statement and at least three Business Days prior to the filing
     of any amendment or supplement thereto, and the Company will not file any
     such Registration Statement or Prospectus or any amendment or supplement to
     any such Registration Statement or Prospectus (including all such documents
     incorporated by reference) to which such Holders shall reasonably object
     within five Business Days or three Business Days, as applicable, after the
     receipt thereof. A Holder shall be deemed to have reasonably objected to
     such filing if such Registration Statement,

                                       12
<PAGE>

     amendment, Prospectus or supplement, as applicable, as proposed to be
     filed, contains an untrue statement of a material fact or omit to state any
     material fact necessary to make the statements therein not misleading or
     fails to comply with the applicable requirements of the Act;

                    (vi)   promptly prior to the filing of any document that is
     to be incorporated by reference into a Registration Statement or
     Prospectus, provide copies of such document to each Holder in connection
     with such exchange or sale, if any, make the Company's and the Guarantors'
     representatives available for discussion of such document and other
     customary due diligence matters, and include such information in such
     document prior to the filing thereof as such Holders may reasonably
     request;

                    (vii)  subject to reasonable confidentiality procedures,
     make available, at reasonable times, for inspection by each Holder and any
     attorney or accountant retained by such Holders, all financial and other
     records, pertinent corporate documents of the Company and the Guarantors
     and cause the Company's and the Guarantors' officers, directors and
     employees to supply all information reasonably requested by any such
     Holder, attorney or accountant in connection with such Registration
     Statement or any post-effective amendment thereto subsequent to the filing
     thereof and prior to its effectiveness;

                    (viii) if requested by any Holders in connection with such
     exchange or sale, promptly include in any Registration Statement or
     Prospectus, pursuant to a supplement or post-effective amendment if
     necessary, such information as such Holders may reasonably request to have
     included therein, including, without limitation, information relating to
     the "Plan of Distribution" of the Transfer Restricted Securities, and make
     all required filings of such Prospectus supplement or post-effective
     amendment as soon as practicable after the Company is notified of the
     matters to be included in such Prospectus supplement or post-effective
     amendment;

                    (ix)   furnish to each Holder in connection with such
     exchange or sale, without charge, at least one copy of the Registration
     Statement, as first filed with the Commission, and of each amendment
     thereto, including all documents incorporated by reference therein and all
     exhibits (including exhibits incorporated therein by reference);

                    (x)    deliver to each Holder, without charge, as many
     copies of the Prospectus (including each preliminary prospectus) and any
     amendment or supplement thereto as such Persons reasonably may request; the
     Company and the Guarantors hereby consent to the use (in accordance with
     law) of the Prospectus and

                                       13
<PAGE>

     any amendment or supplement thereto by each selling Holder in connection
     with the offering and the sale of the Transfer Restricted Securities
     covered by the Prospectus or any amendment or supplement thereto;

                    (xi)   upon the request of any Holder, enter into such
     agreements (including underwriting agreements) and make such
     representations and warranties and take all such other actions in
     connection therewith in order to expedite or facilitate the disposition of
     the Transfer Restricted Securities pursuant to any applicable Registration
     Statement contemplated by this Agreement as may be reasonably requested by
     any Holder in connection with any sale or resale pursuant to any applicable
     Registration Statement. In such connection the Company and the Guarantors
     shall:

                    (A)    upon request of any Holder, furnish (or in the case
          of paragraphs (2) and (3), use its best efforts to cause to be
          furnished) to each Holder, upon Consummation of the Exchange Offer or
          upon the effectiveness of the Shelf Registration Statement, as the
          case may be:

                              (1) a certificate, dated such date, signed on
          behalf of the Company and each Guarantor by (x) the Chief Executive
          Officer, the President or any Vice President and (y) a principal
          financial or accounting officer of the Company and such Guarantor,
          confirming, as of the date thereof, the matters set forth in Sections
          6(y), 9(a) and 9(b) of the Purchase Agreement and such other similar
          matters as such Holders may reasonably request;

                              (2) an opinion, dated the date of Consummation of
          the Exchange Offer or the date of effectiveness of the Shelf
          Registration Statement, as the case may be, of counsel for the Company
          and the Guarantors covering matters similar to those set forth in
          paragraph (e) of Section 9 of the Purchase Agreement and such other
          matters as such Holder may reasonably request, and in any event
          including a statement to the effect that such counsel has participated
          in conferences with officers and other representatives of the Company
          and the Guarantors and representatives of the independent public
          accountants for the Company and the Guarantors and has considered the
          matters required to be stated therein and the statements contained
          therein, although such counsel has not independently verified the
          accuracy, completeness or fairness of such statements; and that such
          counsel advises that, on the basis of the foregoing, no facts came to
          such counsel's attention that caused such counsel to believe that the

                                       14
<PAGE>

          applicable Registration Statement, at the time such Registration
          Statement or any post-effective amendment thereto became effective
          and, in the case of the Exchange Offer Registration Statement, as of
          the date of Consummation of the Exchange Offer, contained an untrue
          statement of a material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading, or that the Prospectus contained in such
          Registration Statement as of its date and, in the case of the opinion
          dated the date of Consummation of the Exchange Offer, as of the date
          of Consummation, contained an untrue statement of a material fact or
          omitted to state a material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading. Without limiting the foregoing, such
          counsel may state further that such counsel assumes no responsibility
          for, and has not independently verified, the accuracy, completeness or
          fairness of the financial statements, notes and schedules and other
          financial data included in any Registration Statement contemplated by
          this Agreement or the related Prospectus; and

                              (3) a customary comfort letter, dated the date of
          Consummation of the Exchange Offer, or as of the date of effectiveness
          of the Shelf Registration Statement, as the case may be, from the
          Company's independent accountants, in the customary form and covering
          matters of the type customarily covered in comfort letters to
          underwriters in connection with underwritten offerings, and affirming
          the matters set forth in the comfort letters delivered pursuant to
          Section 9(g) of the Purchase Agreement; and

                       (B) deliver such other documents and certificates as may
          be reasonably requested by the selling Holders to evidence compliance
          with the matters covered in clause (A) above and with any customary
          conditions contained in any agreement entered into by the Company and
          the Guarantors pursuant to this clause (xi);

                       (xii) prior to any public offering of Transfer Restricted
     Securities, cooperate with the selling Holders and their counsel in
     connection with the registration and qualification of the Transfer
     Restricted Securities under the securities or Blue Sky laws of such
     jurisdictions as the selling Holders may request and do any and all other
     acts or things necessary or advisable to enable the disposition in such
     jurisdictions of the Transfer Restricted Securities covered by the
     applicable Registration Statement; provided, however, that neither the
     Company nor

                                       15
<PAGE>

     any Guarantor shall be required to register or qualify as a foreign
     corporation where it is not now so qualified or to take any action that
     would subject it to the service of process in suits or to taxation, other
     than as to matters and transactions relating to the Registration Statement,
     in any jurisdiction where it is not now so subject;

                       (xiii) in connection with any sale of Transfer Restricted
     Securities that will result in such securities no longer being Transfer
     Restricted Securities, cooperate with the Holders to facilitate the timely
     preparation and delivery of certificates representing Transfer Restricted
     Securities to be sold and not bearing any restrictive legends; and to
     register such Transfer Restricted Securities in such denominations and such
     names as the selling Holders may request at least two Business Days prior
     to such sale of Transfer Restricted Securities;

                       (xiv)  use their respective best efforts to cause the
     disposition of the Transfer Restricted Securities covered by the
     Registration Statement to be registered with or approved by such other
     governmental agencies or authorities as may be necessary to enable the
     seller or sellers thereof to consummate the disposition of such Transfer
     Restricted Securities, subject to the proviso contained in clause (xii)
     above;

                       (xv)   provide a CUSIP number for all Transfer Restricted
     Securities not later than the effective date of a Registration Statement
     covering such Transfer Restricted Securities and provide the Trustee under
     the Indenture with printed certificates for the Transfer Restricted
     Securities which are in a form eligible for deposit with the Depository
     Trust Company;

                       (xvi)  otherwise use their respective best efforts to
     comply with all applicable rules and regulations of the Commission, and
     make generally available to its security holders with regard to any
     applicable Registration Statement, as soon as practicable, a consolidated
     earnings statement meeting the requirements of Rule 158 (which need not be
     audited) covering a twelve-month period beginning after the effective date
     of the Registration Statement (as such term is defined in paragraph (c) of
     Rule 158 under the Act);

                       (xvii) cause the Indenture to be qualified under the TIA
     not later than the effective date of the first Registration Statement
     required by this Agreement and, in connection therewith, cooperate with the
     Trustee and the Holders to effect such changes to the Indenture as may be
     required for such Indenture to be so qualified in accordance with the terms
     of the TIA; and execute and use its best efforts to cause the Trustee to
     execute, all documents that may be required to effect such

                                       16
<PAGE>

     changes and all other forms and documents required to be filed with the
     Commission to enable such Indenture to be so qualified in a timely manner;
     and

                       (xviii) provide promptly to each Holder, upon request,
     each document filed with the Commission pursuant to the requirements of
     Section 13 or Section 15(d) of the Exchange Act.

            (d)     Restrictions on Holders. Each Holder agrees by
                    -----------------------
     acquisition of a Transfer Restricted Security that, upon receipt of the
     notice referred to in Section 6(c)(iii)(C) or any notice from the Company
     of the existence of any fact of the kind described in Section 6(c)(iii)(D)
     hereof (in each case, a "Suspension Notice"), such Holder will forthwith
                              -----------------
     discontinue disposition of Transfer Restricted Securities pursuant to the
     applicable Registration Statement until (i) such Holder has received copies
     of the supplemented or amended Prospectus contemplated by Section 6(c)(iv)
     hereof, or (ii) such Holder is advised in writing by the Company that the
     use of the Prospectus may be resumed, and has received copies of any
     additional or supplemental filings that are incorporated by reference in
     the Prospectus (in each case, the "Recommencement Date"). Each Holder
                                        -------------------
     receiving a Suspension Notice hereby agrees that it will either (i) destroy
     any Prospectuses, other than permanent file copies, then in such Holder's
     possession which have been replaced by the Company with more recently dated
     Prospectuses or (ii) deliver to the Company (at the Company's expense) all
     copies, other than permanent file copies, then in such Holder's possession
     of the Prospectus covering such Transfer Restricted Securities that was
     current at the time of receipt of the Suspension Notice. The time period
     regarding the effectiveness of such Registration Statement set forth in
     Section 3 or 4 hereof, as applicable, shall be extended by a number of days
     equal to the number of days in the period from and including the date of
     delivery of the Suspension Notice to the date of delivery of the
     Recommencement Date.

     SECTION 7.  REGISTRATION EXPENSES

            (a)     All expenses incident to the Company's and the Guarantors'
     performance of or compliance with this Agreement will be borne by the
     Company, regardless of whether a Registration Statement becomes effective,
     including without limitation: (i) all registration and filing fees and
     expenses; (ii) all fees and expenses of compliance with federal securities
     and state Blue Sky or securities laws; (iii) all expenses of printing
     (including printing certificates for the Series B Notes to be issued in the
     Exchange Offer and printing of Prospectuses), messenger and delivery
     services and telephone; (iv) all fees and disbursements of counsel for the
     Company and the Guarantors, and, in accordance with Section 7(b) below, the
     Holders of Transfer Restricted Securities; (v) all application and filing
     fees in connection with

                                       17

     listing the Series B Notes on a national securities exchange or automated
     quotation system pursuant to the requirements hereof; and (vi) all fees and
     disbursements of independent certified public accountants of the Company
     and the Guarantors (including the expenses of any special audit and comfort
     letters required by or incident to such performance).

            The Company will, in any event, bear its and the Guarantors'
     internal expenses (including, without limitation, all salaries and expenses
     of its officers and employees performing legal or accounting duties), the
     expenses of any annual audit and the fees and expenses of any Person,
     including special experts, retained by the Company or the Guarantors.

            (b)     In connection with any Registration Statement required by
     this Agreement (including, without limitation, the Exchange Offer
     Registration Statement and the Shelf Registration Statement), the Company
     and the Guarantors will reimburse the Initial Purchasers and the Holders of
     Transfer Restricted Securities who are tendering Series A Notes into in the
     Exchange Offer and/or selling or reselling Series A Notes or Series B Notes
     pursuant to the "Plan of Distribution" contained in the Exchange Offer
     Registration Statement or the Shelf Registration Statement, as applicable,
     for the reasonable fees and disbursements of not more than one counsel, who
     shall be chosen by the Holders of a majority in principal amount of the
     Transfer Restricted Securities for whose benefit such Registration
     Statement is being prepared.

     SECTION 8.  INDEMNIFICATION

            (a)     The Company and the Guarantors agree, jointly and severally,
     to indemnify and hold harmless each Holder, its directors, officers and
     each Person, if any, who controls such Holder (within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act), from and against
     any and all losses, claims, damages, liabilities, judgments, (including
     without limitation, any legal or other expenses incurred in connection with
     investigating or defending any matter, including any action that could give
     rise to any such losses, claims, damages, liabilities or judgments) caused
     by any untrue statement or alleged untrue statement of a material fact
     contained in any Registration Statement, preliminary prospectus or
     Prospectus (or any amendment or supplement thereto) provided by the Company
     to any Holder or any prospective purchaser of Series B Notes or registered
     Series A Notes, or caused by any omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to make
     the statements therein not misleading, except insofar as such losses,
     claims, damages, liabilities or judgments are caused by an untrue statement
     or omission or alleged untrue statement or omission that is based

                                       18
<PAGE>

     upon information relating to any of the Holders furnished in writing to the
     Company by any of the Holders provided, however, that the Company shall not
     be liable under the indemnity agreement provided in this Section 8(a) to
     any indemnified party (as defined below) with respect to any preliminary
     prospectus to the extent that the Company shall sustain the burden of
     proving that any such loss, claim, damage, liability or judgment resulted
     from the fact that such indemnified party, in contravention of a
     requirement of applicable law, sold Transfer Restricted Securities to a
     person to whom such indemnified party failed to send or give, on or prior
     to the closing date of such sale, a copy of the Prospectus, as then amended
     or supplemented, if (i) the Company has previously furnished copies thereof
     (sufficiently in advance of such closing date to allow for distribution by
     the closing date) to such indemnified party, and the loss, claim, damage,
     liability or judgment of such indemnified party resulted from an untrue
     statement or omission or a material fact contained in or omitted from the
     preliminary prospectus that was corrected in the Prospectus as, if
     applicable, amended or supplemented prior to such closing date, and such
     Prospectus was required by law to be delivered at or prior to the written
     confirmation of sale to such person and (ii) such failure to give or send
     such Prospectus by such closing date to the party or parties asserting such
     loss, claim, damage, liability or judgment would have constituted a defense
     to the claim asserted by such person.

            (b)     Each Holder of Transfer Restricted Securities agrees,
     severally and not jointly, to indemnify and hold harmless the Company and
     the Guarantors, and their respective directors and officers, and each
     person, if any, who controls (within the meaning of Section 15 of the Act
     or Section 20 of the Exchange Act) the Company or the Guarantors, to the
     same extent as the foregoing indemnity from the Company and the Guarantors
     set forth in section (a) above, but only with reference to information
     relating to such Holder furnished in writing to the Company by such Holder
     expressly for use in any Registration Statement. In no event shall any
     Holder, its directors, officers or any Person who controls such Holder be
     liable or responsible for any amount in excess of the amount by which the
     total amount received by such Holder with respect to its sale of Transfer
     Restricted Securities pursuant to a Registration Statement exceeds (i) the
     amount paid by such Holder for such Transfer Restricted Securities and (ii)
     the amount of any damages that such Holder, its directors, officers or any
     Person who controls such Holder has otherwise been required to pay by
     reason of such untrue or alleged untrue statement or omission or alleged
     omission.

            (c)     In case any action shall be commenced involving any person
     in respect of which indemnity may be sought pursuant to Sec Section 8(a) or
     8(b) (the "indemnified party"), the indemnified party shall promptly notify
                -----------------
     the person against

                                       19
<PAGE>

     whom such indemnity may be sought (the "indemnifying person") in writing
                                             -------------------
     and the indemnifying party shall assume the defense of such action,
     including the employment of counsel reasonably satisfactory to the
     indemnified party and the payment of all fees and expenses of such counsel,
     as incurred (except that in the case of any action in respect of which
     indemnity may be sought pursuant to both Sections 8(a) and 8(b), a Holder
     shall not be required to assume the defense of such action pursuant to this
     Section 8(c), but may employ separate counsel and participate in the
     defense thereof, but the fees and expenses of such counsel, except as
     provided below, shall be at the expense of the Holder). Any indemnified
     party shall have the right to employ separate counsel in any such action
     and participate in the defense thereof, but the fees and expenses of such
     counsel shall be at the expense of the indemnified party unless (i) the
     employment of such counsel shall have been specifically authorized in
     writing by the indemnifying party, (ii) the indemnifying party shall have
     failed to assume the defense of such action or employ counsel reasonably
     satisfactory to the indemnified party or (iii) the named parties to any
     such action (including any impleaded parties) include both the indemnified
     party and the indemnifying party, and the indemnified party shall have been
     advised by such counsel that there may be one or more legal defenses
     available to it which are different from or additional to those available
     to the indemnifying party (in which case the indemnifying party shall not
     have the right to assume the defense of such action on behalf of the
     indemnified party). In any such case, the indemnifying party shall not, in
     connection with any one action or separate but substantially similar or
     related actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the fees and expenses of more
     than one separate firm of attorneys (in addition to any local counsel) for
     all indemnified parties and all such fees and expenses shall be reimbursed
     as they are incurred. Such firm shall be designated in writing by a
     majority of the Holders, in the case of the parties indemnified pursuant to
     Section 8(a), and by the Company and Guarantors, in the case of parties
     indemnified pursuant to Section 8(b). The indemnifying party shall
     indemnify and hold harmless the indemnified party from and against any and
     all losses, claims, damages, liabilities and judgments by reason of any
     settlement of any action (i) effected with its written consent or (ii)
     effected without its written consent if the settlement is entered into more
     than twenty business days after the indemnifying party shall have received
     a request from the indemnified party for reimbursement for the fees and
     expenses of counsel (in any case where such fees and expenses are at the
     expense of the indemnifying party) and, prior to the date of such
     settlement, the indemnifying party shall have failed to comply with such
     reimbursement request. No indemnifying party shall, without the prior
     written consent of the indemnified party, effect any settlement or
     compromise of, or consent to the entry of judgment with respect to, any
     pending or threatened action in respect of which the indemnified party is
     or could have been a party and indemnity or contribution may be or could
     have been sought

                                       20
<PAGE>

hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action 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 the indemnified party.

          (d)  To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company and
the Guarantors, on the one hand, and the Holders, on the other hand, from their
sale of Transfer Restricted Securities or (ii) if the allocation provided by
clause 8(d)(i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause
8(d)(i) above but also the relative fault of the Company and the Guarantors, on
the one hand, and of the Holder, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors, on the one
hand, and of the Holder, on the other hand, shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or such Guarantor, on the one hand, or by
the Holder, on the other hand, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and judgments referred to above shall be deemed to
include, subject to the limitations set forth in the second paragraph of Section
8(a), any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim.

          The Company, the Guarantors and each Holder agree that it would not be
just and equitable if contribution pursuant to this Section 8(d) were determined
by pro rata allocation (even if the Holders 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 the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating

                                       21
<PAGE>

or defending any matter, including any action that could have given rise to such
losses, claims, damages, liabilities or judgments. Notwithstanding the
provisions of this Section 8, no Holder, its directors, its officers or any
Person, if any, who controls such Holder shall be required to contribute, in the
aggregate, any amount in excess of the amount by which the total received by
such Holder with respect to the sale of Transfer Restricted Securities pursuant
to a Registration Statement exceeds (i) the amount paid by such Holder for such
Transfer Restricted Securities and (ii) 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. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Holders' obligations to contribute pursuant to this
Section 8(c) are several in proportion to the respective principal amount of
Transfer Restricted Securities held by each Holder hereunder and not joint.

SECTION 9. RULE 144A and RULE 144

          The Company and each Guarantor agrees with each Holder, for so long as
any Transfer Restricted Securities remain outstanding and during any period in
which the Company or such Guarantor (i) is not subject to Section 13 or 15(d) of
the Exchange Act, to make available, upon request of any Holder, to such Holder
or beneficial owner of Transfer Restricted Securities in connection with any
sale thereof and any prospective purchaser of such Transfer Restricted
Securities designated by such Holder or beneficial owner, the information
required by Rule 144A(d)(4) under the Act in order to permit resales of such
Transfer Restricted Securities pursuant to Rule 144A, and (ii) is subject to
Section 13 or 15 (d) of the Exchange Act, to make all filings required thereby
in a timely manner in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144.

SECTION 10.    MISCELLANEOUS

          (a) Remedies.  The Company and the Guarantors acknowledge and agree
              --------
that any failure by the Company and/or the Guarantors to comply with their
respective obligations under Sections 3 and 4 hereof may result in material
irreparable injury to the Initial Purchasers or the Holders  for which there is
no adequate remedy at law, that it will not be possible to measure damages for
such injuries precisely and that, in the event of any such failure, the Initial
Purchasers or any Holder may obtain such relief as may be required to
specifically enforce the Company's and the Guarantor's obligations under
Sections 3 and 4 hereof.  The Company and the Guarantors further agree to waive
the defense in any action for specific performance that a remedy at law would be
adequate.

                                       22
<PAGE>

          (b) No Inconsistent Agreements.  Neither the Company nor any Guarantor
              --------------------------
will, on or after the date of this Agreement, enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any Guarantor is currently a party to any agreement
granting any registration rights with respect to its securities to any Person.
The rights granted to the Holders hereunder do not in any way conflict with and
are not inconsistent with the rights granted to the holders of the Company's and
the Guarantors' securities under any agreement in effect on the date hereof.

          (c) Amendments and Waivers.  The provisions of this Agreement may not
              ----------------------
be amended, modified or supplemented, and waivers or consents to or departures
from the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 10(c)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates).  Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer, and that does not affect directly or indirectly the rights
of other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer, may be given by the Holders of a majority of
the outstanding principal amount of Transfer Restricted Securities subject to
such Exchange Offer.

          (d) Third Party Beneficiary.  The Holders shall be third party
              -----------------------
beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent they may
deem such enforcement necessary or advisable to protect its rights or the rights
of Holders hereunder.

              -------
