      Section 2. Exchange Offer

            (a) Unless the Exchange Offer would violate applicable law or
interpretation of the staff of the Commission, the Issuers shall (i) file a
Registration Statement (the "Exchange Offer Registration Statement") with the
Commission on an appropriate registration form with respect to a registered
offer (the "Exchange Offer") to exchange any and all of the Registrable Notes
for a like aggregate principal amount of notes (including the guarantees with
respect thereto, the "Exchange Notes") that are identical in all material
respects to the Notes (except that the Exchange Notes shall not contain
restrictive legends, terms with respect to transfer restrictions or Additional
Interest upon a Registration Default) on or prior to 180 days after the Issue
Date, (ii) use their reasonable best efforts to cause the Exchange Offer
Registration Statement to be declared effective under the Securities Act

<PAGE>

                                       -5-

on or prior to 240 days after the Issue Date and (iii) use their reasonable best
efforts to consummate the Exchange Offer within 280 days after the Issue Date.
Upon the Exchange Offer Registration Statement being declared effective by the
Commission, the Issuers will offer the Exchange Notes in exchange for surrender
of the Notes. The Issuers shall keep the Exchange Offer open for not less than
30 days (or longer if required by applicable law) after the date notice of the
Exchange Offer is mailed to Holders.

            Each Holder that participates in the Exchange Offer will be required
to represent to the Issuers in writing that (i) any Exchange Notes to be
acquired in the Exchange Offer will be acquired in the ordinary course of
business of the person receiving such Exchange Notes, whether or not such
recipient is such Holder itself, (ii) it has no arrangement or understanding
with any Person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes in violation of the provisions of the
Securities Act, (iii) it is not an affiliate of the Company or any Guarantor as
defined by Rule 405 of the Securities Act or, if it is such an affiliate, it
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, it is not engaged in, and does not intend to engage in, a
distribution of Exchange Notes and (v) if such Holder is a broker-dealer that
will receive Exchange Notes for its own account in exchange for Notes that were
acquired as a result of market-making or other trading activities, it will
comply with the applicable provision of the Securities Act (including, but not
limited to, the prospectus delivery requirements thereunder) in connection with
any resale of such Exchange Notes.

            (b) The Issuers and the Initial Purchasers acknowledge that the
staff of the Commission has taken the position that any broker-dealer that
elects to exchange Notes that were acquired by such broker-dealer for its own
account as a result of market-making or other trading activities for Exchange
Notes in the Exchange Offer (a "Participating Broker-Dealer") may be deemed to
be an "underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Notes (other than a resale of an unsold allotment
resulting from the original offering of the Notes).

            The Issuers and the Initial Purchasers also acknowledge that the
staff of the Commission has taken the position that if the Prospectus contained
in the Exchange Offer Registration Statement includes a plan of distribution
containing a statement to the above effect and the means by which Participating
Broker-Dealers may resell the Exchange Notes, without naming the Participating
Broker-Dealers or specifying the amount of Exchange Notes owned by them, such
Prospectus may be delivered by Participating Broker-Dealers to satisfy their
prospectus delivery obligations under the Securities Act in connection with
resales of Exchange Notes for their own accounts, so long as the Prospectus
otherwise meets the requirements of the Securities Act.

            In light of the foregoing, if requested by a Participating
Broker-Dealer (a "Requesting Participating Broker-Dealer"), the Issuers agree to
use their reasonable best efforts to keep the Exchange Offer Registration
Statement continuously effective for a period necessary to comply with
applicable law in connection with such resales but in no event more than 180
days after the date on which the Exchange Registration Statement is declared
effective, or such longer period if extended pursuant to any Delay Period in
accordance with the penultimate paragraph of Section 5 hereof (such period, the
"Applicable Period"), or such earlier date as each Requesting Participating
Broker-Dealer

<PAGE>

                                       -6-

shall have notified the Company in writing that such Requesting Participating
Broker-Dealer has resold all Exchange Notes acquired by it in the Exchange
Offer. The Issuers shall include a plan of distribution in such Exchange Offer
Registration Statement that meets the requirements set forth in the immediately
preceding paragraph.

            If, prior to consummation of the Exchange Offer, any Initial
Purchaser or any other Holder holds any Notes acquired by it that have, or that
are reasonably likely to be determined to have, the status of an unsold
allotment in an initial distribution, or if any Holder is not entitled to
participate in the Exchange Offer, the Issuers upon the request of the Initial
Purchasers or any such Holder, as the case may be, shall simultaneously with the
delivery of the Exchange Notes in the Exchange Offer, issue and deliver to the
Initial Purchasers or any such Holder, as the case may be, in exchange (the
"Private Exchange") for such Notes held by such Initial Purchaser or any such
Holder a like principal amount of notes (the "Private Exchange Notes") of the
Issuers that are identical in all material respects to the Exchange Notes except
that the Private Exchange Notes may be subject to restrictions on transfer and
bear a legend to such effect. The Private Exchange Notes shall be issued
pursuant to the same indenture as the Exchange Notes and bear the same CUSIP
number as the Exchange Notes (if permitted by the CUSIP Service Bureau).

            Upon consummation of the Exchange Offer in accordance with this
Section 2, the Issuers shall have no further registration obligations other than
the Issuers' continuing registration obligations with respect to (i) Private
Exchange Notes, (ii) Exchange Notes held by Participating Broker-Dealers and
(iii) Notes or Exchange Notes as to which clause (c)(iv) of this Section 2
applies.

            In connection with the Exchange Offer, the Issuers shall:

            (1) mail or cause to be mailed to each Holder entitled to
      participate in the Exchange Offer a copy of the Prospectus forming part of
      the Exchange Offer Registration Statement, together with an appropriate
      letter of transmittal and related documents;

            (2) utilize the services of a depositary for the Exchange Offer with
      an address in the Borough of Manhattan, The City of New York;

            (3) permit Holders to withdraw tendered Notes at any time prior to
      the close of business, New York time, on the last Business Day on which
      the Exchange Offer shall remain open; and

            (4) otherwise comply in all material respects with all applicable
      laws, rules and regulations.

            As soon as practicable after the close of the Exchange Offer and the
Private Exchange, if any, the Issuers shall:

            (1) accept for exchange all Notes validly tendered and not validly
      withdrawn by the Holders pursuant to the Exchange Offer and the Private
      Exchange, if any;

<PAGE>

                                       -7-

            (2) deliver or cause to be delivered to the Trustee for cancellation
      all Registrable Notes so accepted for exchange; and

            (3) cause the Trustee to authenticate and deliver promptly to each
      such Holder of Notes, Exchange Notes or Private Exchange Notes, as the
      case may be, equal in principal amount to the Registrable Notes of such
      Holder so accepted for exchange; provided that, in the case of any Notes
      held in global form by a depositary, authentication and delivery to such
      depositary of one or more replacement Notes in global form in an
      equivalent principal amount thereto for the account of such Holders in
      accordance with the Indenture shall satisfy such authentication and
      delivery requirement.

            The Exchange Offer and the Private Exchange shall not be subject to
any conditions, other than that (i) the Exchange Offer or Private Exchange, as
the case may be, does not violate applicable law or any applicable
interpretation of the staff of the Commission, (ii) no action or proceeding
shall have been instituted or threatened in any court or by any governmental
agency which might materially impair the ability of the Issuers to proceed with
the Exchange Offer or the Private Exchange, and no material adverse development
shall have occurred in any existing action or proceeding with respect to the
Issuers and (iii) all governmental approvals shall have been obtained, which
approvals the Company deems necessary for the consummation of the Exchange Offer
or Private Exchange.

            The Exchange Notes and the Private Exchange Notes shall be issued
under (i) the Indenture or (ii) an indenture identical in all material respects
to the Indenture (in either case, with such changes as are necessary to comply
with any requirements of the Commission to effect or maintain the qualification
thereof under the TIA) and which, in either case, has been qualified under the
TIA and shall provide that (a) the Exchange Notes shall not be subject to the
transfer restrictions set forth in the Indenture and (b) the Private Exchange
Notes shall be subject to the transfer restrictions set forth in the Indenture.
The Indenture or such indenture shall provide that the Exchange Notes, the
Private Exchange Notes and the Notes shall vote and consent together on all
matters as one class and that none of the Exchange Notes, the Private Exchange
Notes or the Notes will have the right to vote or consent as a separate class on
any matter.

            (c) In the event that (i) because of any change in law or in
currently prevailing interpretations of the staff of the Commission, the Issuers
are not permitted to effect the Exchange Offer, or (ii) the Initial Purchasers
or any other Holder of Notes notifies the Company in writing within 20 days
after the consummation of the Exchange Offer that (A) it is prohibited by law or
Commission policy from participating in the Exchange Offer, (B) that it may not
resell the Exchange 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 or
(C) that it is a broker-dealer and owns Notes acquired directly from the Company
or an affiliate of the Company (each such event referred to in clauses (i) or
(ii) of this sentence, a "Shelf Filing Event"), then the Issuers shall file a
Shelf Registration pursuant to Section 3 hereof.

<PAGE>

                                       -8-

      Section 3. Shelf Registration

            If at any time a Shelf Filing Event shall occur, then:

            (a) Shelf Registration. The Issuers shall file with the Commission a
      Registration Statement for an offering to be made on a continuous basis
      pursuant to Rule 415 covering all of the Registrable Notes not exchanged
      in the Exchange Offer, Private Exchange Notes and Exchange Notes as to
      which Section 2(c)(ii)(B) is applicable (the "Shelf Registration"). The
      Shelf Registration shall be on an appropriate form permitting registration
      of such Registrable Notes for resale by Holders in the manner or manners
      designated by them (including, without limitation, one or more
      underwritten offerings). The Issuers shall not permit any securities other
      than the Registrable Notes to be included in the Shelf Registration.

            (b) The Issuers shall (x) cause the Shelf Registration to be filed
      with the Commission on or prior to 180 days after the date of the Shelf
      Filing Event giving rise to the obligation to file the Shelf Registration
      and shall use their reasonable best efforts to cause the Shelf
      Registration to be declared effective under the Securities Act on or prior
      to the 240th day after the date of the Shelf Filing Event giving rise to
      the obligation to file the Shelf Registration and (y) to keep the Shelf
      Registration continuously effective under the Securities Act for the
      period ending on the date which is two years from the Issue Date, subject
      to extension pursuant to the penultimate paragraph of Section 5 hereof
      (the "Effectiveness Period"), or such shorter period ending when all
      Registrable Notes covered by the Shelf Registration have been sold in the
      manner set forth and as contemplated in the Shelf Registration; provided,
      however, that (i) the Effectiveness Period in respect of the Shelf
      Registration shall be extended to the extent required to permit dealers to
      comply with the applicable prospectus delivery requirements of Rule 174
      under the Securities Act and as otherwise provided herein and (ii) the
      Company may suspend the effectiveness of the Shelf Registration by written
      notice to the Holders solely (A) as a result of the filing of a
      post-effective amendment to the Shelf Registration to incorporate annual
      audited financial information with respect to the Company where such
      post-effective amendment is not yet effective and needs to be declared
      effective to permit Holders to use the related Prospectus or (B) to the
      extent and for so long as permitted by the penultimate paragraph of
      Section 5.

            (c) Supplements and Amendments. The Issuers agree to supplement or
      make amendments to the Shelf Registration as and when required by the
      rules, regulations or instructions applicable to the registration form
      used for such Shelf Registration or by the Securities Act or rules and
      regulations thereunder for shelf registration, or if reasonably requested
      by the Holders of a majority in aggregate principal amount of the
      Registrable Notes covered by such Registration Statement or by any
      underwriter of such Registrable Notes.

      Section 4. Additional Interest

            (a) The Issuers and the Initial Purchasers agree that the Holders
will suffer damages if the Issuers fail to fulfill their obligations under
Section 2 or Section 3 hereof and that it would not be feasible to ascertain the
extent of such damages with precision. Accordingly, the Issuers agree that if:

<PAGE>

                                       -9-

            (i) the Exchange Offer Registration Statement has not been filed on
      or prior to the 180th day following the Issue Date, or, if that day is not
      a Business Day, the next day that is a Business Day, or

            (ii) the Exchange Offer Registration Statement has not been declared
      effective on or prior to the 240th day following the Issue Date, or, if
      that day is not a Business Day, the next day that is a Business Day, or

            (iii) the Exchange Offer is not consummated on or prior to the 280th
      day following the Issue Date, or, if that day is not a Business Day, the
      next day that is a Business Day; or

            (iv) the Shelf Registration is required to be filed but is not
      declared effective within the time period specified in Section 3(b)(x), or

            (v) the Exchange Offer Registration Statement or Shelf Registration,
      as the case may be, is declared effective by the date required hereunder
      but thereafter ceases to be effective or usable during the Applicable
      Period, with respect to an Exchange Offer Registration Statement, or the
      Effectiveness Period, with respect to a Shelf Registration (unless the
      Exchange Offer Registration Statement or Shelf Registration, as the case
      may be, ceases to be effective or usable as specifically permitted by the
      penultimate paragraph of Section 5 hereof),

(each such event referred to in clauses (i)-(v) a "Registration Default"),
additional interest in the form of additional cash interest ("Additional
Interest") will accrue on the affected Registrable Notes. The rate of Additional
Interest will be 0.25% per annum for the first 90-day period immediately
following the occurrence of a Registration Default, increasing by an additional
0.25% per annum with respect to each subsequent 90-day period up to a maximum
amount of Additional Interest of 1.00% per annum, from and including the date on
which any such Registration Default shall occur to, but excluding, the earlier
of (1) the date on which all Registration Defaults have been cured or (2) the
date on which such Registrable Note ceases to be a Registrable Note or otherwise
become freely transferable by Holders other than affiliates of the Issuers
without further registration under the Securities Act. If, after the cure of all
Registration Defaults then in effect, there is a subsequent Registration
Default, the rate of Additional Interest for such subsequent Registration
Default shall initially be 0.25% regardless of the rate in effect with respect
to any prior Registration Default at the time of cure of such Registration
Default and shall increase in the manner and be subject to the maximum
Additional Interest rate contained in the preceding sentence.

            Notwithstanding the foregoing, (1) the amount of Additional Interest
payable shall not increase because more than one Registration Default has
occurred and is pending and (2) a Holder of Registrable Notes that is not
entitled to the benefits of the Shelf Registration (e.g., such Holder has not
elected to include information) shall not be entitled to Additional Interest
with respect to a Registration Default that pertains to the Shelf Registration.

            (b) So long as Notes remain outstanding, the Company shall notify
the Trustee within five Business Days after each and every date on which an
event occurs in respect of which Additional Interest is required to be paid. Any
amounts of Additional Interest due pursuant to clauses (a)(i), (a)(ii), (a)(iii)
or (a)(iv) of this Section 4 will be payable in cash semi-annually on each March
1

<PAGE>

                                      -10-

and September 1 (each an "Additional Interest Payment Date"), commencing with
the first such date occurring after any such Additional Interest commences to
accrue, to Holders to whom regular interest is payable on such Additional
Interest Payment Date with respect to Notes that are Registrable Notes. The
amount of Additional Interest for each Registrable Note will be determined by
multiplying the applicable rate of Additional Interest by the aggregate
principal amount of such Registrable Note outstanding on the Additional Interest
Payment Date following such Registration Default in the case of the first such
payment of Additional Interest with respect to a Registration Default (and
thereafter at the next succeeding Additional Interest Payment Date until the
cure of such Registration Default), and multiplying the product of the foregoing
by a fraction, the numerator of which is the number of days such Additional
Interest rate was applicable during such period (determined on the basis of a
360-day year comprised of twelve 30-day months and, in the case of a partial
month, the actual number of days elapsed), and the denominator of which is 360.

      Section 5. Registration Procedures

            In connection with the filing of any Registration Statement pursuant
to Section 2 or 3 hereof, the Issuers shall effect such registrations to permit
the sale of the securities covered thereby in accordance with the intended
method or methods of disposition thereof, and pursuant thereto and in connection
with any Registration Statement filed by the Issuers hereunder, the Issuers
shall:

            (a) Use their reasonable best efforts to prepare and file with the
      Commission the Registration Statement or Registration Statements
      prescribed by Section 2 or 3 hereof, and use their reasonable best efforts
      to cause each such Registration Statement to become effective and remain
      effective as provided herein; provided, however, that, if (1) such filing
      is pursuant to Section 3 hereof, or (2) a Prospectus contained in the
      Exchange Offer Registration Statement filed pursuant to Section 2 hereof
      is required to be delivered under the Securities Act by any Participating
      Broker-Dealer who seeks to sell Exchange Notes during the Applicable
      Period relating thereto, before filing any Registration Statement or
      Prospectus or any amendments or supplements thereto, the Issuers shall
      furnish to and afford the Holders of the Registrable Notes covered by such
      Registration Statement or each such Participating Broker-Dealer, as the
      case may be, their counsel (if requested by any such person) and the
      managing underwriters, if any, a reasonable opportunity to review copies
      of all such documents (including copies of any documents to be
      incorporated by reference therein and all exhibits thereto) proposed to be
      filed (in each case at least five Business Days prior to such filing). The
      Issuers shall not file any Registration Statement or Prospectus or any
      amendments or supplements thereto if the Holders of a majority in
      aggregate principal amount of the Registrable Notes covered by such
      Registration Statement, or any such Participating Broker-Dealer, as the
      case may be, their counsel, or the managing underwriters, if any, shall
      reasonably object.

            (b) Use their reasonable best efforts to prepare and file with the
      Commission such amendments and post-effective amendments to each Shelf
      Registration or Exchange Offer Registration Statement, as the case may be,
      as may be necessary to keep such Registration Statement continuously
      effective for the Effectiveness Period or the Applicable Period, as the
      case may be; cause the related Prospectus to be supplemented by any
      Prospectus supplement required by applicable law, and as so supplemented
      to be filed pursuant to Rule 424 (or any similar provisions then in force)
      promulgated under the Securities Act; and comply with the

<PAGE>

                                      -11-

      applicable provisions of the Securities Act and the Exchange Act with
      respect to the disposition of all securities covered by such Registration
      Statement as so amended or in such Prospectus as so supplemented and with
      respect to the subsequent resale of any securities being sold by a
      Participating Broker-Dealer covered by any such Prospectus, in each case,
      in accordance with the intended methods of distribution set forth in such
      Registration Statement or Prospectus, as so amended or supplemented.

            (c) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof, or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period relating thereto from
      whom the Company has received written notice that such Participating
      Broker-Dealer will be a Participating Broker-Dealer in the applicable
      Exchange Offer, notify the selling Holders of Registrable Notes, or each
      such Participating Broker-Dealer, as the case may be, their counsel (if
      such counsel is known to the Issuers) and the managing underwriters, if
      any, as promptly as possible, and, if requested by any such Person,
      confirm such notice in writing, (i) when a Prospectus or any Prospectus
      supplement or post-effective amendment has been filed, and, with respect
      to a Registration Statement or any post-effective amendment, when the same
      has become effective under the Securities Act (including in such notice a
      written statement that any Holder may, upon request, obtain, at the sole
      expense of the Issuers, one conformed copy of such Registration Statement
      or post-effective amendment including financial statements and schedules,
      documents incorporated or deemed to be incorporated by reference and
      exhibits), (ii) of the issuance by the Commission of any stop order
      suspending the effectiveness of a Registration Statement or of any order
      preventing or suspending the use of any preliminary prospectus or the
      initiation of any proceedings for that purpose, (iii) if at any time when
      a Prospectus is required by the Securities Act to be delivered in
      connection with sales of the Registrable Notes or resales of Exchange
      Notes by Participating Broker-Dealers the representations and warranties
      of the Issuers contained in any agreement (including any underwriting
      agreement) contemplated by Section 5(m) hereof cease to be true and
      correct in all material respects, (iv) of the receipt by any of the
      Issuers of any notification with respect to the suspension of the
      qualification or exemption from qualification of a Registration Statement
      or any of the Registrable Notes or the Exchange Notes for offer or sale in
      any jurisdiction, or the initiation or threatening of any proceeding for
      such purpose, (v) of the happening of any event, the existence of any
      condition or any information becoming known to any Issuer that makes any
      statement made in such Registration Statement or related Prospectus or any
      document incorporated or deemed to be incorporated therein by reference
      untrue in any material respect or that requires the making of any changes
      in or amendments or supplements to such Registration Statement, Prospectus
      or documents so that, in the case of the Registration Statement, it will
      not contain any untrue statement of a material fact or omit to state any
      material fact required to be stated therein or necessary to make the
      statements therein not misleading, and that in the case of the Prospectus,
      it will not contain any untrue statement of a material fact or omit to
      state any material fact required to be stated therein or necessary to make
      the statements therein, in the light of the circumstances under which they
      were made, not misleading, and (vi) of the Company's determination that a
      post-effective amendment to a Registration Statement would be appropriate.

                                      -12-

            (d) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof, or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, use their reasonable
      best efforts to prevent the issuance of any order suspending the
      effectiveness of a Registration Statement or of any order preventing or
      suspending the use of a Prospectus or suspending the qualification (or
      exemption from qualification) of any of the Registrable Notes or the
      Exchange Notes, as the case may be, for sale in any jurisdiction, and, if
      any such order is issued, to use their reasonable best efforts to obtain
      the withdrawal of any such order at the earliest practicable moment.

            (e) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period and if requested by the
      managing underwriter or underwriters (if any), the Holders of a majority
      in aggregate principal amount of the Registrable Notes covered by such
      Registration Statement or any Participating Broker-Dealer, as the case may
      be, (i) promptly incorporate in such Registration Statement or Prospectus
      a prospectus supplement or post-effective amendment such information as
      the managing underwriter or underwriters (if any), such Holders or any
      Participating Broker-Dealer, as the case may be (based upon advice of
      counsel), determine is reasonably required to be included therein and (ii)
      make all required filings of such prospectus supplement or such
      post-effective amendment as soon as practicable after the Company has
      received notification of the matters to be incorporated in such prospectus
      supplement or post-effective amendment; provided, however, that the
      Issuers shall not be required to take any action hereunder that would, in
      the written opinion of counsel to the Issuers, violate applicable laws.

            (f) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, furnish to each selling
      Holder of Registrable Notes or each such Participating Broker-Dealer, as
      the case may be, who so requests, their counsel (if requested by any such
      person) and each managing underwriter, if any, at the sole expense of the
      Issuers, one conformed copy of the Registration Statement or Registration
      Statements and each post-effective amendment thereto, including financial
      statements and schedules, and, if requested, all documents incorporated or
      deemed to be incorporated therein by reference and all exhibits.

            (g) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof, or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, deliver to each selling
      Holder of Registrable Notes or each such Participating Broker-Dealer, as
      the case may be, their respective counsel (if requested) and the
      underwriters, if any, at the sole expense of the Issuers, as many copies
      of the Prospectus or Prospectuses (including each form of preliminary
      prospectus) and each amendment or supplement thereto and any documents
      incorporated by ref-

<PAGE>
                                      -13-

      erence therein as such Persons may reasonably request; and, subject to the
      last paragraph of this Section 5, the Issuers hereby consent to the use of
      such Prospectus and each amendment or supplement thereto by each of the
      selling Holders of Registrable Notes or each such Participating
      Broker-Dealer, as the case may be, and the underwriters or agents, if any,
      and dealers (if any), in connection with the offering and sale of the
      Registrable Notes covered by, or the sale by Participating Broker-Dealers
      of the Exchange Notes pursuant to, such Prospectus and any amendment or
      supplement thereto.

            (h) Prior to any public offering of Registrable Notes or Exchange
      Notes or any delivery of a Prospectus contained in the Exchange Offer
      Registration Statement by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, use their reasonable
      best efforts to register or qualify, and to cooperate with the selling
      Holders of Registrable Notes or each such Participating Broker-Dealer, as
      the case may be, the managing underwriter or underwriters, if any, and
      their respective counsel in connection with the registration or
      qualification (or exemption from such registration or qualification) of
      such Registrable Notes or Exchange Notes, as the case may be, for offer
      and sale under the securities or Blue Sky laws of such jurisdictions
      within the United States as any selling Holder, Participating
      Broker-Dealer, or the managing underwriter or underwriters reasonably
      request; provided, however, that where Exchange Notes or Registrable Notes
      are offered other than through an underwritten offering, the Issuers agree
      to cause the Issuers' counsel to perform Blue Sky investigations and file
      registrations and qualifications required to be filed pursuant to this
      Section 5(h); keep each such registration or qualification (or exemption
      therefrom) effective during the period such Registration Statement is
      required to be kept effective and do any and all other acts or things
      reasonably necessary or advisable to enable the disposition in such
      jurisdictions of such Exchange Notes or Registrable Notes covered by the
      applicable Registration Statement; provided, however, that no Issuer shall
      be required to (A) qualify generally to do business in any jurisdiction
      where it is not then so qualified, (B) take any action that would subject
      it to general service of process in any such jurisdiction where it is not
      then so subject or (C) subject itself to taxation in excess of a nominal
      dollar amount in any such jurisdiction where it is not then so subject.

            (i) If a Shelf Registration is filed pursuant to Section 3 hereof,
      cooperate with the selling Holders of Registrable Notes and the managing
      underwriter or underwriters, if any, to facilitate the timely preparation
      and delivery of certificates representing Registrable Notes to be sold,
      which certificates shall not bear any restrictive legends and shall be in
      a form eligible for deposit with The Depository Trust Company; and enable
      such Registrable Notes to be in such denominations and registered in such
      names as the managing underwriter or underwriters, if any, or selling
      Holders may request at least two Business Days prior to any sale of such
      Registrable Notes.

            (j) Use their reasonable best efforts to cause the Registrable Notes
      or Exchange Notes covered by any Registration Statement to be registered
      with or approved by such other governmental agencies or authorities as may
      be reasonably necessary to enable the seller or sellers thereof or the
      underwriter or underwriters, if any, to consummate the disposition of such
      Registrable Notes or Exchange Notes, except as may be required solely as a
      consequence of the nature of such selling Holder's business, in which case
      the Issuers will cooperate in all

<PAGE>

                                      -14-

      reasonable respects with the filing of such Registration Statement and the
      granting of such approvals.

            (k) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof, or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, upon the occurrence of
      any event contemplated by Section 5(c)(v) or 5(c)(vi) hereof, as promptly
      as practicable prepare and (subject to Section 5(a) and the penultimate
      paragraph of this Section 5) file with the Commission, at the sole expense
      of the Issuers, a supplement or post-effective amendment to the
      Registration Statement or a supplement to the related Prospectus or any
      document incorporated or deemed to be incorporated therein by reference,
      or file any other required document so that, as thereafter delivered to
      the purchasers of the Registrable Notes being sold thereunder or to the
      purchasers of the Exchange Notes to whom such Prospectus will be delivered
      by a Participating Broker-Dealer, any such Prospectus will not contain an
      untrue statement of a material fact or omit to state a material fact
      required to be stated therein or necessary to make the statements therein,
      in the light of the circumstances under which they were made, not
      misleading.

            (l) Prior to the effective date of the first Registration Statement
      relating to the Registrable Notes, (i) provide the Trustee with
      certificates for the Registrable Notes in a form eligible for deposit with
      The Depository Trust Company and (ii) provide a CUSIP number for the
      Registrable Notes.

            (m) In connection with any underwritten offering of Registrable
      Notes pursuant to a Shelf Registration, enter into an underwriting
      agreement as is customary in underwritten offerings of debt securities
      similar to the Notes and take all such other actions as are reasonably
      requested by the managing underwriter or underwriters in order to expedite
      or facilitate the registration or the disposition of such Registrable
      Notes and, whether or not such offering is an underwritten offering, (i)
      make such representations and warranties to the managing underwriter or
      underwriters, if any, (and to any Holder that has advised the Company that
      such Holder may have a "due diligence" defense under Section 11 of the
      Securities Act), and covenants with, the underwriters with respect to the
      business of the Issuers and their subsidiaries (including any acquired
      business, properties or entity, if applicable), and the Registration
      Statement, Prospectus and documents, if any, incorporated or deemed to be
      incorporated by reference therein, in each case, as are customarily made
      by issuers to underwriters in underwritten offerings of debt securities
      similar to the Notes, and confirm the same in writing if and when
      reasonably requested; (ii) use their reasonable best efforts to obtain the
      written opinions of counsel to the Issuers and written updates thereof in
      form, scope and substance reasonably satisfactory to the managing
      underwriter or underwriters, addressed to the underwriters (and to any
      Holder that has advised the Company that such Holder may have a "due
      diligence" defense under Section 11 of the Securities Act) covering the
      matters customarily covered in opinions requested in underwritten
      offerings and such other matters as may be reasonably requested by the
      managing underwriter or underwriters; (iii) use their reasonable best
      efforts to obtain "cold comfort" letters and updates thereof in form,
      scope and substance reasonably satisfactory to the managing underwriter or
      underwriters from the independent certified public

<PAGE>
                                      -15-

      accountants of the Issuers (and, if necessary, any other independent
      certified public accountants of any subsidiary of the Company or of any
      business acquired by the Company for which financial statements and
      financial data are, or are required to be, included or incorporated by
      reference in the Registration Statement), addressed to each of the
      underwriters (and to any Holder that has advised the Company that such
      Holder may have a "due diligence" defense under Section 11 of the
      Securities Act), such letters to be in customary form and covering matters
      of the type customarily covered in "cold comfort" letters in connection
      with underwritten offerings; and (iv) if an underwriting agreement is
      entered into, the same shall contain indemnification provisions and
      procedures no less favorable than those set forth in Section 7 hereof (or
      such other provisions and procedures acceptable to Holders of a majority
      in aggregate principal amount of Registrable Notes covered by such
      Registration Statement and the managing underwriter or underwriters or
      agents) with respect to all parties to be indemnified pursuant to said
      Section; provided that the Issuers shall not be required to provide
      indemnification to any underwriter selected in accordance with the
      provisions of Section 9 hereof with respect to information relating to
      such underwriter furnished in writing to the Company by or on behalf of
      such underwriter expressly for inclusion in such Registration Statement;
      provided, further that the Company shall not be required to enter into
      more than two such underwriting agreements with respect to underwritten
      offerings of Registrable Notes. The above shall be done at each closing
      under such underwriting agreement, or as and to the extent required
      thereunder.

            (n) If (1) a Shelf Registration is filed pursuant to Section 3
      hereof or (2) a Prospectus contained in the Exchange Offer Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, make available for
      inspection by any selling Holder of such Registrable Notes being sold or
      each such Participating Broker-Dealer, as the case may be, any underwriter
      participating in any such disposition of Registrable Notes, if any, and
      any attorney, accountant or other agent retained by any such selling
      Holder or each such Participating Broker-Dealer, as the case may be, or
      underwriter (collectively, the "Inspectors"), at the offices where
      normally kept, during reasonable business hours, all financial and other
      records, pertinent corporate documents and instruments of the Company and
      its subsidiaries (collectively, the "Records") as shall be reasonably
      necessary to enable them to exercise any applicable due diligence
      responsibilities, and cause the officers, directors and employees of the
      Company and its subsidiaries to supply all information reasonably
      requested by any such Inspector in connection with such Registration
      Statement and Prospectus. Each Inspector shall agree in writing that it
      will keep the Records confidential and that it will not disclose, or use
      in connection with any market transactions in violation of any applicable
      securities laws, any Records that the Company determines, in good faith,
      to be confidential and that it notifies the Inspectors in writing are
      confidential unless (i) the disclosure of such Records is necessary to
      avoid or correct a misstatement or omission in such Registration Statement
      or Prospectus, (ii) the release of such Records is ordered pursuant to a
      subpoena or other order from a court of competent jurisdiction, (iii)
      disclosure of such information is necessary or advisable in the opinion of
      counsel for an Inspector in connection with any action, claim, suit or
      proceeding, directly or indirectly, involving or potentially involving
      such Inspector and arising out of, based upon, relating to, or involving
      this Agreement or the Purchase Agreement, or any transactions contemplated
      hereby or thereby or arising hereunder or there-

<PAGE>
                                      -16-

      under, or (iv) the information in such Records has been made generally
      available to the public; provided, however, that (i) each Inspector shall
      agree to use reasonable best efforts to provide notice to the Company of
      the potential disclosure of any information by such Inspector pursuant to
      clause (i), (ii) or (iii) of this sentence to permit the Issuers to obtain
      a protective order (or waive the provisions of this paragraph (n)) and
      (ii) each such Inspector shall take such actions as are reasonably
      necessary to protect the confidentiality of such information (if
      practicable) to the extent such action is otherwise not inconsistent with,
      an impairment of or in derogation of the rights and interests of the
      Holder or any Inspector.

            (o) Provide an indenture trustee for the Registrable Notes or the
      Exchange Notes, as the case may be, and cause the Indenture or the trust
      indenture provided for in Section 2(a) hereof to be qualified under the
      TIA not later than the effective date of the Exchange Offer or the first
      Registration Statement relating to the Registrable Notes; and in
      connection therewith, cooperate with the trustee under any such indenture
      and the Holders of the Registrable Notes or Exchange Notes, as applicable,
      to effect such changes to such indenture as may be required for such
      indenture to be so qualified in accordance with the terms of the TIA; and
      execute, and use their reasonable best efforts to cause such trustee to
      execute, all documents as may be required to effect such 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.

            (p) Comply with all applicable rules and regulations of the
      Commission and make generally available to the Company's securityholders
      earnings statements satisfying the provisions of Section 11(a) of the
      Securities Act and Rule 158 thereunder (or any similar rule promulgated
      under the Securities Act) after the end of any 12-month period no later
      than the number of days permitted for the filing of Quarterly Reports on
      Form 10-Q by accelerated filers (as defined in the Exchange Act) (or after
      the end of any 12-month period if such period is a fiscal year no later
      than the number of days permitted for the filing of Annual Reports on Form
      10-K by accelerated filers (as defined in the Exchange Act)) (i)
      commencing at the end of any fiscal quarter in which Registrable Notes or
      Exchange Notes are sold to underwriters in a firm commitment or best
      efforts underwritten offering and (ii) if not sold to underwriters in such
      an offering, commencing on the first day of the first fiscal quarter of
      the Company after the effective date of a Registration Statement, which
      statements shall cover said 12-month periods consistent with the
      requirements of Rule 158.

            (q) Upon the request of a Holder, upon consummation of the Exchange
      Offer or a Private Exchange, use their reasonable best efforts to obtain
      an opinion of counsel to the Issuers, in a form customary for underwritten
      transactions, addressed to the Trustee for the benefit of all Holders of
      Registrable Notes participating in the Exchange Offer or the Private
      Exchange, as the case may be, that the Exchange Notes or Private Exchange
      Notes, as the case may be, and the related indenture constitute legal,
      valid and binding obligations of the Issuers, enforceable against the
      Issuers in accordance with its respective terms, subject to customary
      exceptions and qualifications.

            (r) If the Exchange Offer or a Private Exchange is to be
      consummated, upon delivery of the Registrable Notes by Holders to the
      Company (or to such other Person as directed by the Company) in exchange
      for the Exchange Notes or the Private Exchange Notes, as the

<PAGE>
                                      -17-

      case may be, mark, or cause to be marked, on such Registrable Notes that
      such Registrable Notes are being cancelled in exchange for the Exchange
      Notes or the Private Exchange Notes, as the case may be; provided that in
      no event shall such Registrable Notes be marked as paid or otherwise
      satisfied.

            (s) Cooperate with each seller of Registrable Notes covered by any
      Registration Statement and each underwriter, if any, participating in the
      disposition of such Registrable Notes and their respective counsel in
      connection with any filings required to be made with the NASD.

            (t) Use their reasonable best efforts to take all other steps
      reasonably necessary or advisable to effect the registration of the
      Exchange Notes and/or Registrable Notes covered by a Registration
      Statement contemplated hereby.

            The Company may require each seller of Registrable Notes or Exchange
Notes as to which any registration is being effected to furnish to the Company
such information regarding such seller and the distribution of such Registrable
Notes or Exchange Notes as the Company may, from time to time, reasonably
request. The Company may exclude from such registration the Registrable Notes of
any seller so long as such seller fails to furnish such information within a
reasonable time after receiving such request and, in the event of such an
exclusion, the Issuers shall have no further obligation under this Agreement
(including, without limitation, the obligations under Section 4) with respect to
such seller or any subsequent Holder of such Registrable Notes. Each seller as
to which any Shelf Registration is being effected agrees to furnish promptly to
the Company all information required to be disclosed in order to make any
information previously furnished to the Company by such seller not materially
misleading.

            If any such Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company or the Guarantors, then
such Holder shall have the right to require (i) the insertion therein of
language, in form and substance reasonably satisfactory to such Holder, to the
effect that the holding by such Holder of such securities is not to be construed
as a recommendation by such Holder of the investment quality of the securities
covered thereby and that such holding does not imply that such Holder will
assist in meeting any future financial requirements of the Company or the
Guarantors, or (ii) in the event that such reference to such Holder by name or
otherwise is not required by the Securities Act or any similar federal statute
then in force, the deletion of the reference to such Holder in any amendment or
supplement to the applicable Registration Statement filed or prepared subsequent
to the time that such reference ceases to be required.

            Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by acquisition of such Registrable Notes or Exchange Notes
that, upon the Company providing notice to such Holder or Participating
Broker-Dealer, as the case may be, (x) of the happening of any event of the kind
described in Section 5(c)(ii), 5(c)(iii), 5(c)(iv), or 5(c)(v) hereof, or (y)
that the Board of Directors of the Company (the "Board of Directors") has
resolved that the Company has a bona fide business purpose for doing so, then,
upon providing such notice (which shall refer to the penultimate paragraph of
this Section 5), the Issuers may delay the filing or the effectiveness of the
Exchange Offer Registration Statement or the Shelf Registration (if not then
filed or effective, as applicable) and shall not be required to maintain the
effectiveness thereof or amend or supplement the Exchange Offer

<PAGE>

                                      -18-

Registration Statement or the Shelf Registration, in all cases, for a period (a
"Delay Period") expiring upon the earlier to occur of (i) in the case of the
immediately preceding clause (x), such Holder's or Participating Broker-Dealer's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 5(k) hereof or until it is advised in writing (the "Advice") by the
Company that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or supplements thereto or (ii) in the case of
the immediately preceding clause (y), the date which is the earlier of (A) the
date on which such business purpose ceases to interfere with the Issuers'
obligations to file or maintain the effectiveness of any such Registration
Statement pursuant to this Agreement or (B) 60 days after the Company notifies
the Holders of such good faith determination. There shall not be more than 60
days of Delay Periods during any 12-month period. The maximum length of the
Applicable Period set forth in Section 2(b) shall be extended by a number of
days equal to the number of days during any Delay Period. Any Delay Period will
not alter the obligations of the Issuers to pay Additional Interest under the
circumstances set forth in Section 4 hereof.

            Each Holder or Participating Broker-Dealer, by its acceptance of any
Registrable Note, agrees that during any Delay Period, each Holder or
Participating Broker-Dealer will discontinue disposition of such Notes or
Exchange Notes covered by such Registration Statement or Prospectus or Exchange
Notes to be sold by such Holder or Participating Broker-Dealer, as the case may
be.

      Section 6. Registration Expenses

            All fees and expenses incident to the performance of or compliance
with this Agreement by the Issuers (other than any underwriting discounts or
commissions) shall be borne by the Issuers, whether or not the Exchange Offer
Registration Statement or the Shelf Registration is filed or becomes effective
or the Exchange Offer is consummated, including, without limitation, (i) all
registration and filing fees (including, without limitation, fees and expenses
of compliance with state securities or Blue Sky laws (including, without
limitation, reasonable fees and disbursements of counsel in connection with Blue
Sky qualifications of the Registrable Notes or Exchange Notes and determination
of the eligibility of the Registrable Notes or Exchange Notes for investment
under the laws of such jurisdictions (x) where the holders of Registrable Notes
are located, in the case of an Exchange Offer, or (y) as provided in Section
5(h) hereof, in the case of a Shelf Registration or in the case of Exchange
Notes to be sold by a Participating Broker-Dealer during the Applicable
Period)), (ii) printing expenses, including, without limitation, expenses of
printing certificates for Registrable Notes or Exchange Notes in a form eligible
for deposit with The Depository Trust Company and of printing prospectuses if
the printing of prospectuses is requested by the managing underwriter or
underwriters, if any, or by the Holders of a majority in aggregate principal
amount of the Registrable Notes included in any Registration Statement or in
respect of Exchange Notes to be sold by any Participating Broker-Dealer during
the Applicable Period, as the case may be, (iii) messenger, telephone and
delivery expenses, (iv) fees and disbursements of counsel for the Issuers and
the reasonable fees and disbursements of one special counsel for all of the
sellers of Registrable Notes (exclusive of any counsel retained pursuant to
Section 7 hereof) selected by the Holders of a majority in aggregate principal
amount of Notes, Exchange Notes and Private Exchange Notes being registered and
reasonably satisfactory to the Issuers, (v) fees and disbursements of all
independent certified public accountants referred to in Section 5(m)(iii) hereof
(including, without limitation, the expenses of any special audit and "cold
comfort" letters required by or incident to such performance), (vi) Securities
Act liability insurance, if the Issuers desire such insurance, (vii) fees and
expenses of all other Persons retained by

<PAGE>
                                      -19-

any of the Issuers, (viii) internal expenses of the Issuers (including, without
limitation, all salaries and expenses of officers and employees of the Company
performing legal or accounting duties), (ix) the expense of any annual audit,
(x) the fees and expenses incurred in connection with the listing of the
securities to be registered on any securities exchange, and the obtaining of a
rating of the securities, in each case, if applicable, (xi) any required fees
and expenses incurred in connection with any filing required to be made with the
NASD and (xii) the expenses relating to printing, word processing and
distributing all Registration Statements, underwriting agreements, indentures
and any other documents necessary in order to comply with this Agreement.
Notwithstanding the foregoing or anything to the contrary, each Holder shall pay
all underwriting discounts and commissions of any underwriters with respect to
any Registrable Notes sold by or on behalf of it.

      Section 7. Indemnification

            (a) The Issuers, jointly and severally, agree to indemnify and hold
harmless each Holder of Registrable Notes and each Participating Broker-Dealer
selling Exchange Notes during the Applicable Period, each Person, if any, who
controls any such Person within the meaning of Section 15 of the Securities Act
or Section 20(a) of the Exchange Act, the agents, employees, officers and
directors of each Holder and each such Participating Broker-Dealer and the
agents, partners, members, employees, officers, managers and directors of any
such controlling Person (each, a "Participant") from and against any and all
losses, liabilities, claims, damages and expenses whatsoever (including, but not
limited to, reasonable attorneys' fees and any and all reasonable expenses
whatsoever actually incurred in investigating, preparing or defending against
any litigation, commenced or threatened, or any claim whatsoever, and any and
all reasonable amounts paid in settlement of any claim or litigation)
(collectively, "Losses") to which they or any of them may become subject under
the Securities Act, the Exchange Act or otherwise insofar as such Losses (or
actions in respect thereof) arise out of or are based upon any untrue statement
or alleged untrue statement of a material fact contained in any Registration
Statement (or any amendment thereto) or Prospectus (as amended or supplemented
if the Company shall have furnished any amendments or supplements thereto) or
any preliminary prospectus, or caused by, arising out of or based upon any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the case of the
Prospectus, in the light of the circumstances under which they were made, not
misleading, provided that (i) the foregoing indemnity shall not be available to
any Participant insofar as such Losses are caused by any untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with information relating to such Participant furnished to the
Company in writing by or on behalf of such Participant expressly for use
therein, and (ii) the foregoing indemnity with respect to any preliminary
prospectus shall not inure to the benefit of any Participant from whom the
Person asserting such Losses purchased Registrable Notes if (x) it is
established in the related proceeding that such Participant failed to send or
give a copy of the Prospectus (as amended or supplemented if such amendment or
supplement was furnished to such Participant prior to the written confirmation
of such sale) to such Person with or prior to the written confirmation of such
sale, if required by applicable law, and (y) the untrue statement or omission or
alleged untrue statement or omission was completely corrected in the Prospectus
(as amended or supplemented if amended or supplemented as aforesaid) and such
Prospectus does not contain any other untrue statement or omission or alleged
untrue statement or omission that was the subject matter of the related
proceeding. This indemnity agreement will be in addition to any liability that
the Issuers may otherwise have, including, but not limited to, liability under
this Agreement. Notwithstanding anything to the contrary contained herein,

<PAGE>
                                      -20-

any costs or expenses advanced by the Issuers to any Participant pursuant to the
terms of this Section 7(a) shall be promptly reimbursed to the extent that such
Participant is ultimately determined not to have been entitled to
indemnification therefor.

            (b) Each Participant agrees, severally and not jointly, to indemnify
and hold harmless each Issuer, each Person, if any, who controls any Issuer
within the meaning of Section 15 of the Securities Act or Section 20(a) of the
Exchange Act, and each of their respective agents, partners, members, employees,
officers and members of the board of directors from and against any Losses to
which they or any of them may become subject under the Securities Act, the
Exchange Act or otherwise insofar as such Losses (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in any Registration Statement (or any amendment
thereto) or Prospectus (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto) or any preliminary prospectus,
or caused by, arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in the case of the Prospectus, in the light of the
circumstances under which they were made, not misleading, in each case to the
extent, but only to the extent, that any such Loss arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged
omission made in reliance upon and in conformity with information relating to
such Participant furnished in writing to the Company by or on behalf of such
Participant expressly for use therein.

            (c) Promptly after receipt by an indemnified party under subsection
7(a) or 7(b) above of notice of the commencement of any action, suit or
proceeding (collectively, an "action"), such indemnified party shall, if a claim
in respect thereof is to be made against the indemnifying party under such
subsection, notify each party against whom indemnification is to be sought in
writing of the commencement of such action (but the failure so to notify an
indemnifying party shall not relieve such indemnifying party from any liability
that it may have under this Section 7 except to the extent that it has been
prejudiced in any material respect by such failure). In case any such action is
brought against any indemnified party, and it notifies an indemnifying party of
the commencement of such action, the indemnifying party will be entitled to
participate in such action and, to the extent it may elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such indemnified party, to assume the defense of such action with counsel
reasonably satisfactory to such indemnified party. Notwithstanding the
foregoing, the indemnified party or parties shall have the right to employ its
or their own counsel in any such action, but the reasonable fees and expenses of
such counsel shall be at the expense of such indemnified party or parties unless
(i) the employment of such counsel and the payment of such fees and expenses by
the indemnifying party shall have been authorized and agreed to in writing by
the indemnifying parties in connection with the defense of such action, (ii) the
indemnifying parties shall not have employed counsel to take charge of the
defense of such action within a reasonable time after notice of commencement of
the action, or (iii) the named parties to such action (including any impleaded
parties) include such indemnified party and the indemnifying party or parties
(or such indemnifying parties have assumed the defense of such action), and such
indemnified party or parties shall have reasonably concluded, after consultation
with counsel, that there may be defenses available to it or them that are
different from or additional to those available to one or all of the
indemnifying parties (in which case the indemnifying parties shall not have the
right to direct the defense of such action on behalf of the indemnified party or
parties), in any of which events such reasonable fees and expenses of such
counsel shall be borne by the indemnifying

<PAGE>

                                      -21-

parties. In no event shall the indemnifying party be liable for the reasonable
fees and expenses of more than one counsel (together with appropriate local
counsel) at any time for all indemnified parties in connection with any one
action or separate but substantially similar or related actions arising in the
same jurisdiction out of the same general allegations or circumstances. Any such
separate firm for the Participants shall be designated in writing by
Participants who sold a majority in interest of Registrable Notes sold by all
such Participants and shall be reasonably acceptable to the Company and any such
separate firm for the Issuers, their affiliates, officers, directors,
representatives, employees and agents and such control Person of such Issuers
shall be designated in writing by such Issuers and shall be reasonably
acceptable to the Holders. An indemnifying party shall not be liable for any
settlement of any claim or action effected without its written consent, which
consent may not be unreasonably withheld. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement (x) includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such proceeding and (y) does not include a statement as to or an
admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

            (d) In order to provide for contribution in circumstances in which
the indemnification provided for in this Section 7 is for any reason held to be
unavailable from the indemnifying party for any Losses referred to therein, or
is insufficient to hold harmless a party indemnified under this Section 7 for
any Losses referred to therein, each indemnifying party shall contribute to the
amount paid or payable by such indemnified party as a result of such aggregate
Losses (i) in such proportion as is appropriate to reflect the relative benefits
received by each indemnifying party, on the one hand, and each indemnified
party, on the other hand, from the sale of the Notes to the Initial Purchasers
or the resale of the Registrable Notes by such Holder, as applicable, or (ii) if
such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of each indemnified party, on the one hand,
and each indemnifying party, on the other hand, in connection with the
statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations. The relative benefits received by the
Issuers, on the one hand, and each Participant, on the other hand, shall be
deemed to be in the same proportion as (x) the total proceeds from the sale of
the Notes to the Initial Purchasers (net of discounts and commissions but before
deducting expenses) received by the Issuers are to (y) the total net profit
received by such Participant in connection with the sale of the Registrable
Notes. The relative fault of the parties 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 Issuers or such Participant and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission or alleged statement or omission.

            (e) The parties agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation that does not take into account the
equitable considerations referred to above. Notwithstanding the provisions of
this Section 7, (i) in no case shall any Participant be required to contribute
any amount in excess of the amount by which the net profit received by such
Participant in connection with the sale of the Registrable Notes exceeds the
amount of any damages that such Participant has otherwise been

<PAGE>

                                      -22-

required to pay by reason of any untrue or alleged untrue statement or omission
or alleged omission and (ii) no person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. Any party entitled to contribution will, promptly after
receipt of notice of commencement of any action against such party in respect of
which a claim for contribution may be made against another party or parties
under this Section 7, notify such party or parties from whom contribution may be
sought, but the omission to so notify such party or parties shall not relieve
the party or parties from whom contribution may be sought from any obligation it
or they may have under this Section 7 or otherwise, except to the extent that it
has been prejudiced in any material respect by such failure; provided, however,
that no additional notice shall be required with respect to any action for which
notice has been given under this Section 7 for purposes of indemnification.
Anything in this section to the contrary notwithstanding, no party shall be
liable for contribution with respect to any action or claim settled without its
written consent; provided, however, that such written consent was not
unreasonably withheld.

      Section 8. Rules 144 and 144A

            The Issuers covenant that they will file the reports required, if
any, to be filed by them under the Securities Act and the Exchange Act and the
rules and regulations adopted by the Commission thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and,
if at any time the Issuers are not required to file such reports, they will,
upon the request of any Holder or beneficial owner of Registrable Notes, make
available such information necessary to permit sales pursuant to Rule 144A under
the Securities Act. The Issuers further covenant that for so long as any
Registrable Notes remain outstanding they will take such further action as any
Holder of Registrable Notes may reasonably request from time to time to enable
such Holder to sell Registrable Notes without registration under the Securities
Act within the limitation of the exemptions provided by (a) Rule 144(k) and Rule
144A under the Securities Act, as such Rules may be amended from time to time,
or (b) any similar rule or regulation hereafter adopted by the Commission.

      Section 9. Underwritten Registrations

            If any of the Registrable Notes covered by any Shelf Registration
are to be sold in an underwritten offering, the investment banker or investment
bankers and manager or managers that will manage the offering will be selected
by the Holders of a majority in aggregate principal amount of such Registrable
Notes included in such offering and shall be reasonably acceptable to the
Company.

            No Holder of Registrable Notes may participate in any underwritten
registration hereunder if such Holder does not (a) agree to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
complete and execute all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

      Section 10. Miscellaneous

            (a) No Inconsistent Agreements. The Issuers have not, as of the date
hereof, and shall not, after the date of this Agreement, enter into any
agreement with respect to any of their securi-

<PAGE>

                                      -23-

ties that is inconsistent with the rights granted to the Holders of Registrable
Notes in this Agreement or otherwise conflicts with the provisions hereof. The
rights granted to the Holders hereunder do not conflict with and are not
inconsistent with, in any material respect, the rights granted to the holders of
any of the Issuers' other issued and outstanding securities under any such
agreements. The Issuers have not entered and will not enter into any agreement
with respect to any of their securities which will grant to any Person
piggy-back registration rights with respect to any Registration Statement.

            (b) Adjustments Affecting Registrable Notes. The Issuers shall not,
directly or indirectly, take any action with respect to the Registrable Notes as
a class that would adversely affect the ability of the Holders of Registrable
Notes to include such Registrable Notes in a registration undertaken pursuant to
this Agreement.

            (c) Amendments and Waivers. The provisions of this Agreement may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given except pursuant to a written agreement
duly signed and delivered by (I) the Company (on behalf of all Issuers) and
(II)(A) the Holders of not less than a majority in aggregate principal amount of
the then outstanding Registrable Notes and (B) in circumstances that would
adversely affect the Participating Broker-Dealers, the Participating
Broker-Dealers holding not less than a majority in aggregate principal amount of
the Exchange Notes held by all Participating Broker-Dealers; provided, however,
that Section 7 and this Section 10(c) may not be amended, modified or
supplemented except pursuant to a written agreement duly signed and delivered by
the Issuers and each Holder and each Participating Broker-Dealer (including any
Person who was a Holder or Participating Broker-Dealer of Registrable Notes or
Exchange Notes, as the case may be, disposed of pursuant to any Registration
Statement) affected by any such amendment, modification, waiver or supplement.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Notes whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Notes may be

ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW EXCEPT SECTION 1504-1 OF THE
NEW YORK GENERAL OBLIGATIONS LAW).

            (j) Severability. If any term, provision, covenant or restriction of

illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such

to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

            (k) Securities Held by the Issuers or Their Affiliates. Whenever the

repurchases or redeems Disqualified Stock or preferred stock subsequent to the
commencement of the period for which the Fixed Charge Coverage Ratio is being

calculation of the Fixed Charge Coverage Ratio is made (the "CALCULATION DATE"),
then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect
to such incurrence, assumption, Guarantee, repayment, repurchase, or redemption
of Indebtedness, or such issuance, repurchase or redemption of Disqualified
Stock or preferred stock and the use of the proceeds therefrom as if the same
had occurred at the beginning of the applicable four-quarter reference period.

            In addition, for purposes of calculating the Fixed Charge Coverage
Ratio:

            (1) the Transactions, Investments, acquisitions, dispositions,
      mergers, consolidations and discontinued operations (as determined in
      accordance with GAAP) that have been made by the Issuer or any Restricted
      Subsidiary of the Issuer during the four-quarter reference period or
      subsequent to such reference period and on or prior to or simultaneously
      with the Calculation Date shall be calculated on a pro forma basis
      including Pro Forma Cost Savings assuming that the Transactions and all
      such Investments, acquisitions, dispositions, mergers, consolidations and
      discontinued operations (and the change in any associated fixed charge
      obligations and the change in EBITDA resulting therefrom) had occurred on
      the first day of the four-quarter reference period. If since the beginning
      of such period any Person (that subsequently became a Restricted
      Subsidiary of the Issuer or was merged with or into the Issuer or any
      Restricted Subsidiary of the Issuer since the beginning of such period)
      shall have made any Investment, acquisition, disposition, merger,
      consolidation or discontinued operation that would have required
      adjustment pursuant to this definition, then the Fixed Charge Coverage
      Ratio shall be calculated giving pro forma effect thereto for such period
      as if such Investment, acquisition, disposition, merger, consolidation or
      discontinued operation had occurred at the beginning of the applicable
      four-quarter period; and

            (2) in calculating Fixed Charges attributable to interest on any
      Indebtedness computed on a pro forma basis, (a) interest on outstanding
      Indebtedness determined on a fluctuating basis as of the Calculation Date
      and which will continue to be so determined thereafter shall be deemed to
      have accrued at a fixed rate per annum equal to the rate of interest on
      such Indebtedness in effect on the Calculation Date; (b) if interest on
      any Indebtedness actually incurred on the Calculation Date may optionally
      be determined at an interest rate based upon a factor of a prime or
      similar rate, a eurocurrency interbank offered rate, or other rates, then
      the interest rate in effect on the Calculation Date will be deemed to have
      been in effect during the four-quarter period; and (c) notwithstanding
      clause (a) above, interest on Indebtedness determined on a fluctuating
      basis, to the extent

                                      -10-

Notes thereafter in unlimited amount (so long as permitted by the terms of this
Indenture, including, without limitation, Section 4.10) (any such Notes, the
"ADDITIONAL NOTES") for original issue upon a written order of the Issuer in the
form of an Officers' Certificate in aggregate principal amount as specified in
such order. Each such written order shall specify the principal amount of the
Notes to be authenticated and the date on which the Notes are to be
authenticated.

                                      -28-
<PAGE>

SECTION 2.02. Form and Dating.

            The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto, which is incorporated in and
forms a part of this Indenture. The Notes may have notations, legends or
endorsements required by law, rule or usage to which the Issuer is subject.
Without limiting the generality of the foregoing, Notes offered and sold to
Qualified Institutional Buyers in reliance on Rule 144A ("RULE 144A NOTES")
shall bear the legend and include the form of assignment set forth in Exhibit B,
Notes offered and sold in offshore transactions in reliance on Regulation S
("REGULATION S NOTES") shall bear the legend and include the form of assignment
set forth in Exhibit C, and Notes offered and sold to Institutional Accredited
Investors in transactions exempt from registration under the Securities Act not
made in reliance on Rule 144A or Regulation S ("OTHER NOTES") may be represented
by a Restricted Global Note or, if such an investor may not hold an interest in
the Restricted Global Note, a Physical Note, in each case, bearing the Private
Placement Legend. The Issuer shall approve the form of the Notes and any
notation, legend or endorsement on them. Each Note shall be dated the date of
its issuance and show the date of its authentication.

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

            The Notes may be presented for registration of transfer and exchange
at the offices of the Registrar.

            Notes issued in exchange for interests in a Global Note pursuant to
Section 2.16 may be issued in the form of permanent certificated Notes in
registered form in substantially the form set forth in Exhibit A (the "PHYSICAL
NOTES").

SECTION 2.03. Execution and Authentication.

            One Officer, who shall have been duly authorized by all requisite
corporate actions, shall sign the Notes for the Issuer by manual or facsimile
signature.

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

            No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose unless there appears on such Note a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any Note
shall be conclusive evidence, and the only evidence, that such Note has been
duly authenticated and delivered hereunder. Notwithstanding the foregoing, if
any Note shall have been authenticated and delivered hereunder but never issued
and sold by the Issuer, and the Issuer shall deliver such Note to the Trustee
for cancellation as provided in Section 2.12, for all purposes of this Indenture
such Note shall be deemed never to have been authenticated and delivered
hereunder and shall never be entitled to the benefits of this Indenture.

                                      -29-
<PAGE>

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Issuer to authenticate the Notes. Unless otherwise provided in
the appointment, an authenticating agent may authenticate the Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent. An authenticating agent has the
same rights as an Agent to deal with the Issuer and Affiliates of the Issuer.
Each Paying Agent is designated as an authenticating agent for purposes of this
Indenture.

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

SECTION 2.04. Registrar and Paying Agent.

            The Issuer shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where (a) Notes may be presented or surrendered
for registration of transfer or for exchange ("REGISTRAR"), (b) Notes may be
presented or surrendered for payment ("PAYING AGENT") and (c) notices and
demands to or upon the Issuer in respect of the Notes and this Indenture may be
served. The Issuer 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
Issuer of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York, for such purposes. The Issuer may act as its
own Registrar or Paying Agent, except that for the purposes of Articles Three
and Eight and Sections 4.09 and 4.13, neither the Issuer nor any Affiliate of
the Issuer shall act as Paying Agent. The Registrar shall keep a register of the
Notes and of their transfer and exchange. The Issuer, upon notice to the
Trustee, may have one or more co-Registrars and one or more additional paying
agents reasonably acceptable to the Trustee. The term "Paying Agent" includes
any additional paying agent. The Issuer initially appoints the Trustee as
Registrar and Paying Agent until such time as the Trustee has resigned and a
successor has been appointed. The Issuer may remove any Registrar or Paying
Agent upon written notice to such Registrar or Paying Agent and to the Trustee.

            The Issuer shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent. The Issuer shall notify
the Trustee, in advance, of the name and address of any such Agent. If the
Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as
such.

SECTION 2.05. Paying Agent To Hold Assets in Trust.

            The Issuer shall require each Paying Agent other than the Trustee to
agree in writing that each Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all assets held by the Paying Agent for the payment of,
principal of, premium, if any, or interest on, the Notes (whether such assets
have been distributed to it by the Issuer or any other obligor on the Notes),
and shall notify the Trustee of any Default by the Issuer (or any other obligor
on the Notes) in making any such payment. The Issuer at any time may require a
Paying Agent to promptly distribute all assets held by it to the Trustee and
account for any assets disbursed, and the Trustee may at any time during the
continuance of any payment Default, upon written request

                                      -30-
<PAGE>

to a Paying Agent, require such Paying Agent to promptly distribute all assets
held by it to the Trustee and to account for any assets distributed. Upon
distribution to the Trustee of all assets that shall have been delivered by the
Issuer to the Paying Agent, the Paying Agent shall have no further liability for
such assets.

SECTION 2.06. Holder Lists.

            The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the
Trustee at least two (2) Business Days prior to each Interest Payment Date and
at such other times as the Trustee may request in writing a list in such form
and as of such date as the Trustee may reasonably require of the names and
addresses of Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.07. Transfer and Exchange.

            Subject to Sections 2.16 and 2.17, when Notes are presented to the
Registrar with a request to register the transfer of such Notes or to exchange
such Notes for an equal principal amount of the Notes of other authorized
denominations, the Registrar shall promptly register the transfer or make the
exchange as requested if its requirements for such transaction are met;
provided, however, that the Notes surrendered for transfer or exchange shall be
duly endorsed or accompanied by a written instrument of transfer in form
satisfactory to the Issuer and the Registrar, duly executed by the Holder
thereof or his or her attorney duly authorized in writing. To permit
registrations of transfers and exchanges, the Issuer shall execute and the
Trustee shall authenticate Notes at the Registrar's request. No service charge
shall be made for any registration of transfer or exchange, but the Issuer may
require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith.

            The Registrar shall not be required to register the transfer of or
exchange of any Note (i) during a period beginning at the opening of business 15
days before the mailing of a notice of redemption of the Notes and ending at the
close of business on the day of such mailing, (ii) selected for redemption in
whole or in part pursuant to Article III, except the unredeemed portion of any
Note being redeemed in part, and (iii) during a Change of Control Offer or an
Asset Sale Offer if such Note is tendered pursuant to such Change of Control
Offer or Asset Sale Offer and not withdrawn.

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

SECTION 2.08. Replacement Notes.

            If a mutilated Note is surrendered to the Registrar or the Trustee,
or if the Holder of a Note claims that the Note has been lost, destroyed or
wrongfully taken, the Issuer shall issue and the Trustee shall authenticate a
replacement Note if the Holder of such Note furnishes to the

                                      -31-
<PAGE>

Issuer and the Trustee evidence reasonably acceptable to them of the ownership
and the destruction, loss or theft of such Note and if the requirements of
Section 8-405 of the New York Uniform Commercial Code as in effect on the date
of this Indenture are met. If required by the Trustee or the Issuer, an
indemnity bond shall be posted, sufficient in the judgment of all to protect the
Issuer, if any, the Trustee or any Paying Agent from any loss that any of them
may suffer if such Note is replaced. The Issuer may charge such Holder for the
Issuer's reasonable out-of-pocket expenses in replacing such Note and the
Trustee may charge the Issuer for the Trustee's expenses (including, without
limitation, attorneys' fees and disbursements) in replacing such Note. Every
replacement Note shall constitute a contractual obligation of the Issuer.

SECTION 2.09. Outstanding Notes.

            The Notes outstanding at any time are all the Notes that have been
authenticated by the Trustee except those canceled by it, those delivered to it
for cancellation and those described in this Section as not outstanding. A Note
does not cease to be outstanding because the Issuer or any of its Affiliates
holds the Note (subject to the provisions of Section 2.10).

            If a Note is replaced pursuant to Section 2.08 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding unless
a Responsible Officer of the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser. A mutilated Note ceases to be
outstanding upon surrender of such Note and replacement thereof pursuant to
Section 2.08.

            If the principal of any Note is considered paid under Section 4.01,
it ceases to be outstanding and interest ceases to accrue. If on a Redemption
Date or the Maturity Date the Trustee or Paying Agent (other than the Issuer or
an Affiliate thereof) holds U.S. Legal Tender or Government Securities
sufficient to pay all of the principal of, premium, if any, and interest due on
the Notes payable on that date, then on and after that date such Notes cease to
be outstanding and interest on them ceases to accrue.

SECTION 2.10. Treasury Notes.

            In determining whether the Holders of the required principal amount
of the Notes have concurred in any direction, waiver or consent, Notes owned by
the Issuer or any of its Subsidiaries shall be disregarded, 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 a Responsible Officer of the
Trustee actually knows are so owned shall be disregarded.

            The Issuer is not prohibited from acquiring Notes by means other
than a redemption, whether by tender offer, open market purchases, negotiated
transactions or otherwise, in accordance with applicable securities laws, so
long as such acquisition does not otherwise violate the terms of this Indenture.

SECTION 2.11. Temporary Notes.

            Until definitive Notes are ready for delivery, the Issuer may
prepare and the Trustee shall authenticate temporary Notes. Temporary Notes
shall be substantially in the form of

                                      -32-
<PAGE>

definitive Notes but may have variations that the Issuer considers appropriate
for temporary Notes. Without unreasonable delay, the Issuer shall prepare and
the Trustee shall authenticate definitive Notes in exchange for temporary Notes.
Until such exchange, temporary Notes shall be entitled to the same rights,
benefits and privileges as definitive Notes. Notwithstanding the foregoing, so
long as the Notes are represented by a Global Note, such Global Note may be in
typewritten form.

SECTION 2.12. Cancellation.

            The Issuer at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for transfer, exchange or payment. The Trustee or,
at the direction of the Trustee, the Registrar or the Paying Agent (other than
the Issuer or a Subsidiary), and no one else, shall cancel and, at the written
direction of the Issuer, shall dispose of all Notes surrendered for transfer,
exchange, payment or cancellation in accordance with its customary procedures.
Subject to Section 2.08, the Issuer may not issue new Notes to replace Notes
that it has paid or delivered to the Trustee for cancellation. If the Issuer
shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Notes unless
and until the same are surrendered to the Trustee for cancellation pursuant to
this Section 2.12.

SECTION 2.13. Defaulted Interest.

            If the Issuer defaults in a payment of interest on the Notes, it
shall, unless the Trustee fixes another Record Date pursuant to Section 6.10,
pay the defaulted interest, plus (to the extent lawful) any interest payable on
the defaulted interest, in any lawful manner. The Issuer may pay the defaulted
interest to the persons who are Holders on a subsequent special Record Date,
which special Record Date shall be the fifteenth day next preceding the date
fixed by the Issuer for the payment of defaulted interest or the next succeeding
Business Day if such date is not a Business Day. At least 15 days before any
such subsequent special Record Date, the Issuer shall mail to each Holder, with
a copy to the Trustee, a notice that states the subsequent special Record Date,
the payment date and the amount of defaulted interest, and interest payable on
such defaulted interest, if any, to be paid. The Issuer may make payment of any
defaulted interest in any other lawful manner not inconsistent with the
requirements (if applicable) of any securities exchange on which the Notes may
be listed and, upon such notice as may be required by such exchange, if, after
written notice given by the Issuer to the Trustee of the proposed payment
pursuant to this sentence, such manner of payment shall be deemed practicable by
the Trustee.

SECTION 2.14. CUSIP Number.

            The Issuer in issuing the Notes may use a "CUSIP" number (and
corresponding "ISIN" number), and if so, the Trustee shall use the CUSIP number
in notices of redemption or exchange as a convenience to Holders; provided,
however, that any such notice may state that no representation is made as to the
correctness or accuracy of the CUSIP number printed in the notice or on the
Notes, and that reliance may be placed only on the other identification numbers
printed on the Notes. The Issuer will promptly notify the Trustee of any change
in the CUSIP numbers.

                                      -33-
<PAGE>

SECTION 2.15. Deposit of Moneys.

            Prior to 10:00 a.m. New York City time on each Interest Payment
Date, Maturity Date, Redemption Date, Change of Control Payment Date and Excess
Proceeds Payment Date, the Issuer shall have deposited with the Paying Agent in
immediately available funds money sufficient to make cash payments, if any, due
on such Interest Payment Date, Maturity Date, Redemption Date, Change of Control
Payment Date and Excess Proceeds Payment Date, as the case may be, in a timely
manner which permits the Paying Agent to remit payment to the Holders on such
Interest Payment Date, Maturity Date, Redemption Date, Change of Control Payment
Date and Excess Proceeds Payment Date, as the case may be. The principal of,
premium and interest on Global Notes shall be payable to the Depositary or its
nominee, as the case may be, as the sole registered owner and the sole Holder of
the Global Notes represented thereby. The principal amount and interest on
Physical Notes shall be payable, either in person or by mail, at the office of
the Paying Agent.

SECTION 2.16. Book-Entry Provisions for Global Notes.

            (a) Rule 144A Notes and Other Notes shall be represented by one or
more notes in registered, global form without interest coupons (collectively,
the "RESTRICTED GLOBAL NOTE"). Regulation S Notes initially shall be represented
by one or more notes in registered, global form without interest coupons
(collectively, the "REGULATION S GLOBAL NOTE," and, together with the Restricted
Global Note and any other global notes representing Notes, the "GLOBAL NOTES").
The Global Notes shall bear legends as set forth in Exhibit D. The Global Notes
initially shall (i) be registered in the name of the Depositary or the nominee
of such Depositary, in each case for credit to an account of an Agent Member,
(ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear
legends as set forth in Exhibit B with respect to Restricted Global Notes and
Exhibit C with respect to Regulation S Global Notes.

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

            (b) Transfers of Global Notes shall be limited to transfer in whole,
but not in part, to the Depositary, its successors or their respective nominees.
Interests of Beneficial Owners in the Global Notes may be transferred or
exchanged for Physical Notes in accordance with the rules and procedures of the
Depositary and the provisions of Section 2.17. In addition, a Global Note shall
be exchangeable for Physical Notes if (i) requested by a Holder of such

principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Issuer
shall execute, and the Trustee shall upon receipt of a written order from the
Issuer authenticate and make available for delivery, one or more Physical Notes
of like tenor and amount.

            (d) In connection with the transfer of Global Notes as an entirety

in the Global Notes, an equal aggregate principal amount of Physical Notes of
authorized denominations.

            (e) Any Physical Note constituting a Restricted Security delivered

            (f) On or prior to the end of the "distribution compliance period"
(as defined in Regulation S, the "RESTRICTED PERIOD"), a beneficial interest in
a Regulation S Global Note may be transferred to a Person who takes delivery in
the form of an interest in the corresponding Restricted Global Note only upon
receipt by the Trustee of a written certification from the transferor to the
effect that such transfer is being made (i) (a) to a Person that the transferor
reasonably believes is a Qualified Institutional Buyer in a transaction meeting
the requirements of Rule 144A or (b) pursuant to another exemption from the

            (g) Beneficial interests in the Restricted Global Note may be
transferred to a Person who takes delivery in the form of an interest in the
Regulation S Global Note, whether before or after the expiration of the
Restricted Period, only if the transferor first delivers to the Trustee a
written certificate to the effect that such transfer is being made in accordance
with Regulation S or Rule 144 (if available).

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

      reliance on Rule 144A and

                                      -36-

      it has requested pursuant to Rule 144A or has determined not to request
      such information and that it is aware that the transferor is relying upon
      its foregoing representations in order to claim the exemption from
      registration provided by Rule 144A; and

            (ii) if the proposed transferee is an Agent Member, and the Notes to

            If the Issuer elects to redeem Notes pursuant to Section 5 of the
Notes, it shall notify the Trustee in writing of the Redemption Date, the
Redemption Price and the principal amount of Notes to be redeemed. Subject to
Section 3.03, the Issuer shall give notice of redemption to the Paying Agent and
Trustee at least 45 days but not more than 60 days before the Redemption Date

conditions contained herein.

SECTION 3.02. Selection of Notes To Be Redeemed.

            If less than all of the Notes are to be redeemed at any time, the
Trustee will select Notes for redemption as follows:

            (1) if the Notes are listed on any national securities exchange, in
      compliance with the requirements of the principal national securities
      exchange on which the Notes are listed; or

            (2) if the Notes are not so listed on any national securities
      exchange, on a pro rata basis, by lot or by such method as the Trustee
      shall deem fair and appropriate.

            No Notes of $1,000 or less shall be redeemed in part.

SECTION 3.03. Notice of Redemption.

            At least 30 days but not more than 60 days before a Redemption Date,
the Issuer shall mail a notice of redemption by first class mail, postage
prepaid, to each Holder whose Notes are to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior to
a Redemption Date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction and discharge of this Indenture. At the Issuer's
request, the Trustee shall forward the notice of redemption in the Issuer's name
and at the Issuer's expense; provided that, in such case, the Trustee has
received notice from the Issuer at least 45 days, but not more than 60 days,
before a Redemption Date (unless a shorter notice shall be agreed to in writing
by the Trustee). Notes called for redemption become due on the date fixed for
redemption. On and after the Redemption Date, interest ceases to accrue on Notes
or portions of them called for redemption. Each notice of redemption shall
identify the Notes (including the CUSIP number) to be redeemed and shall state:

            (1) the Redemption Date;

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

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

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

            (5) that, unless the Issuer defaults in making the redemption
      payment, interest on the 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 upon surrender
      to the Paying Agent of the Notes redeemed;

            (6) if any Note is to be redeemed in part only, the portion of the
      principal amount thereof to be redeemed and that a new Note in principal
      amount equal to the unredeemed portion of the original Note will be issued
      in the name of the Holder thereof upon cancellation of the original Note;

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

            (8) the Section of the Notes pursuant to which the Notes are to be
      redeemed.

            The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Note designated for redemption in whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Note. Notices of redemption may not be conditional.

            Once notice of redemption is mailed in accordance with Section 3.03,
Notes called for redemption become due and payable on the Redemption Date and at
the Redemption Price plus accrued interest. Upon surrender to the Trustee or
Paying Agent, such Notes called for redemption shall be paid at the Redemption
Price (which shall include accrued interest thereon to the Redemption Date), but
installments of interest, the maturity of which is on or prior to the Redemption
Date, shall be payable to Holders of record at the close of business on the
relevant Record Dates. On and after the Redemption Date interest ceases to
accrue on Notes or portions of them called for redemption.

SECTION 3.06. Deposit of Redemption Price.

            On or before 10:00 a.m. New York time on the Redemption Date, the
Issuer shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay
the Redemption Price plus accrued interest, of all Notes to be redeemed on that
date.

            If the Issuer complies with the preceding paragraph, then, unless
the Issuer defaults in the payment of such Redemption Price plus accrued
interest, interest ceases to accrue on Notes or portions of them called for
redemption on and after the applicable Redemption Date, whether or not such
Notes are presented for payment.

SECTION 3.07. Notes Redeemed in Part.

            If any Note is to be redeemed in part only, the notice of redemption
that relates to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion of the original Note shall be issued in the name of the Holder thereof
upon cancellation of the original Note.

            (iii) deliver or cause to be delivered to the Trustee all Notes so
      accepted with an Officers' Certificate stating the aggregate principal
      amount of Notes or portions thereof being purchased by the Issuer.

            (d) The Paying Agent will promptly mail to each Holder of Notes so
tendered and not withdrawn the Change of Control Payment for such Notes, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to such Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided, that each such new Note
shall be in a principal amount of $1,000 or an integral multiple thereof.

            (e) Prior to being required to comply with any of the other
provisions of this Section 4.09, but in any event within 90 days following a
Change of Control, the Issuer will either repay all outstanding Senior Debt or
obtain the requisite consents, if any, under all agreements governing
outstanding Senior Debt to permit the repurchase of Notes required by this
Section 4.09.

            (f) Notwithstanding the foregoing, the Issuer will not be required
to make a Change of Control Offer upon a Change of Control if a third party
makes the Change of Control Offer in the manner, at the times and otherwise in
compliance with the requirements set forth in this Indenture applicable to a
Change of Control Offer made by the Issuer and purchases all Notes validly
tendered and not withdrawn under such Change of Control Offer. A Change of
Control Offer may be made in advance of a Change of Control, conditional upon
such Change of Control, if a definitive agreement is in place for the Change of
Control at the time of making of the Change of Control Offer. Notes repurchased
pursuant to a Change of Control Offer will be retired and cancelled.

            (g) The Issuer will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date. The Issuer will comply, and will cause any third party making a Change of
Control Offer to comply, with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of Notes
triggered by a Change of Control Offer. To the extent the provisions of any
applicable securities laws or regulations conflict with Change of Control
provisions of this Indenture, the Issuer will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under this Indenture by virtue of complying with such laws and
regulations.

recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Stock or preferred stock is issued
would have been at least 2.00 to 1, determined on a pro forma basis (including a
pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred Disqualified Stock or preferred stock had been
issued, as the case may be, at the beginning of such four-quarter period.

            (b) Section 4.10(a) will not prohibit the incurrence of any of the
following items of Indebtedness (collectively, "PERMITTED DEBT"):

            (1) (a) the incurrence by the Issuer or any Guarantor of
      Indebtedness under Credit Facilities (and the incurrence by the Guarantors
      of Guarantees thereof) in an aggregate principal amount at any one time
      outstanding (with letters of credit being deemed to have a principal

      by the Issuer or any Guarantor of additional Indebtedness under Credit
      Facilities (and the incurrence by the Guarantors of Guarantees thereof) in

      credit being deemed to have a principal amount equal to the maximum
      potential liability of the Issuer and the Guarantors thereunder) not to
      exceed the amount, if any, by which (x) the amount of the Borrowing Base
      as of the date of such incurrence exceeds (y) the aggregate amount of
      Indebtedness permitted to be incurred pursuant to the immediately
      preceding clause (a) as of the date of such incurrence, less, in the case
      of clause (a), the aggregate amount of all Net Proceeds of Asset Sales,
      applied by the Issuer or any Guarantor to repay any Indebtedness under
      Credit Facilities (and, in the case of any revolving credit Indebtedness
      under a Credit Facility, to effect a corresponding commitment reduction
      thereunder) pursuant to Section 4.13(b)(1) and, in the case of each of
      clauses (a) and (b), less amounts outstanding under any Qualified
      Receivables Transactions;

            (2) the incurrence by the Issuer or any Guarantors of the Existing
      Indebtedness;

            (3) the incurrence by the Issuer and its Restricted Subsidiaries of

      Indenture and related Note Guarantees, the Exchange Notes and the related
      Note Guarantees to be issued pursuant to the Registration Rights
      Agreement; and any Exchange Notes issued by the Issuer in exchange for
      Additional Notes, if any, issued in compliance with this Indenture and
      pursuant to a registered exchange offer and the related Note Guarantees;

            (4) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of Indebtedness represented by Capital Lease Obligations,
      mortgage financings or purchase money

                                      -45-

      obligations, in each case, incurred for the purpose of financing all or
      any part of the purchase price, or cost of construction or improvement, of
      property (real or personal), plant or equipment used in the business of
      the Issuer or any of its Restricted Subsidiaries (whether through the
      direct acquisition of such assets or the acquisition of Equity Interests
      of any Person owning such assets) in an aggregate principal amount,
      including all Permitted Refinancing Indebtedness incurred to refund,
      refinance or replace any Indebtedness incurred pursuant to this clause
      (4), not to exceed, at any time outstanding, the greater of (x) $30.0
      million or (y) 3% of Consolidated Tangible Assets of the Issuer;

      this Indenture to be incurred under Section 4.10(a) or clauses (2), (3),
      (4), (5), (15) or (16) of this Section 4.10(b);

            (6) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of intercompany Indebtedness between or among the Issuer and
      any of its Restricted Subsidiaries; provided, however, that:

                  (a) if the Issuer or any Guarantor is the obligor on such
            Indebtedness, and such Indebtedness is owed to a Restricted
            Subsidiary that is not a Guarantor, such Indebtedness must be
            expressly subordinated to the prior payment in full in cash of all
            Obligations with respect to the Notes, in the case of the Issuer, or
            the Note Guarantee, in the case of a Guarantor; and

                  (b) (i) any subsequent issuance or transfer of Equity
            Interests that results in any such Indebtedness being held by a
            Person other than the Issuer or a Restricted Subsidiary thereof and
            (ii) any sale or other transfer of any such Indebtedness to a Person
            that is not either the Issuer or a Restricted Subsidiary thereof,
            shall be deemed, in each case, to constitute an incurrence of such
            Indebtedness by the Issuer or such Restricted Subsidiary, as the
            case may be, that was not permitted by this clause (6);

            (7) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of Hedging Obligations that are incurred in the ordinary
      course of business for the purpose of fixing, hedging or swapping interest
      rate, commodity price or foreign currency exchange rate risk (or to
      reverse or amend any such agreements previously made for such purposes),
      and not for speculative purposes, and that do not increase the
      Indebtedness of the obligor outstanding at any time other than as a result
      of fluctuations in interest rates, commodity prices or foreign currency
      exchange rates or by reason of fees, indemnities and compensation payable
      thereunder;

            (8) the Guarantee by the Issuer or any Restricted Subsidiary of
      Indebtedness of the Issuer or a Restricted Subsidiary of the Issuer that
      was permitted to be incurred by another provision of this Section 4.10;
      provided that, in the case of a Guarantee of any Restricted Subsidiary
      that is not a Guarantor, such Restricted Subsidiary complies with Section
      4.16;

      original issue discount, the payment of interest on any Indebtedness in
      the form of additional Indebtedness with the same terms, and the payment
      of dividends on Disqualified Stock or preferred stock in the form of
      additional shares of the same class of Disqualified Stock or preferred
      stock will not be deemed to be an incurrence of Indebtedness or an
      issuance of Disqualified Stock or preferred stock for purposes of this
      Section 4.10; provided, in each such case, that the amount thereof is
      included in Fixed Charges of the Issuer as accrued;

            (10) the incurrence by the Issuer's Unrestricted Subsidiaries of
      Non-Recourse Debt; provided, however, that if any such Indebtedness ceases
      to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be
      deemed to constitute an incurrence of Indebtedness by a Restricted
      Subsidiary of the Issuer that was not permitted by this clause (10);

            (11) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of Indebtedness constituting reimbursement obligations with
      respect to letters of credit issued in the ordinary course of business,
      including, without limitation, letters of credit in respect of workers'
      compensation claims or self-insurance, or other Indebtedness with respect
      to reimbursement type obligations regarding workers' compensation claims
      or self-insurance; provided, however, that, upon the drawing of such
      letters of credit or the incurrence of such Indebtedness, such obligations
      are reimbursed within 30 days following such drawing or incurrence;

            (12) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of Indebtedness arising from agreements of the Issuer or such
      Restricted Subsidiary providing for indemnification, adjustment of
      purchase price or similar obligations, in each case, incurred or assumed
      in connection with the disposition of any business, assets or Capital
      Stock of the Issuer or a Restricted Subsidiary, other than Guarantees of
      Indebtedness incurred by any Person acquiring all or any portion of such
      business, assets or a Subsidiary for the purpose of financing such
      acquisition; provided that:

                  (a) such Indebtedness is not reflected on the balance sheet of
            the Issuer or any Restricted Subsidiary (contingent obligations
            referred to in a footnote or footnotes to financial statements and
            not otherwise reflected on the balance sheet will not be deemed to
            be reflected on that balance sheet for purposes of this clause (a));
            and

                  (b) the maximum assumable liability in respect of that
            Indebtedness shall at no time exceed the gross proceeds including
            noncash proceeds (the fair market value of those noncash proceeds
            being measured at the time received and without giving effect to any
            subsequent changes in value) actually received by the Issuer and/or
            that Restricted Subsidiary in connection with that disposition;

            (13) the issuance of Disqualified Stock or preferred stock by any of
      the Issuer's Restricted Subsidiaries issued to the Issuer or another
      Restricted Subsidiary; provided that (i) any subsequent issuance or
      transfer of any Equity Securities that results in such Disqualified Stock
      or preferred stock being held by a Person other than the Issuer or a

                                      -47-

      Restricted Subsidiary thereof and (ii) any sale or other transfer of any
      such shares of Disqualified Stock or preferred stock to a Person that is
      not either the Issuer or a Restricted Subsidiary thereof shall be deemed,
      in each case, to constitute an issuance of such shares of Disqualified
      Stock or preferred stock that was not permitted by this clause (13);

            (14) the incurrence by the Issuer or any of its Restricted
      Subsidiaries of obligations in respect of performance and surety bonds and
      completion Guarantees provided by the Issuer or such Restricted Subsidiary
      in the ordinary course of business;

            (15) the incurrence by the Issuer or any Guarantor of Indebtedness

      pursuant to this clause (16), not to exceed $50.0 million;

            (17) the incurrence of any Indebtedness by a Receivables Subsidiary
      that is not recourse to the Issuer or any other Restricted Subsidiary of
      the Issuer (other than Standard Securitization Undertakings) incurred in
      connection with a Qualified Receivables Transaction; provided, that, the
      aggregate amount of Indebtedness under this clause (17), when aggregated
      with all Indebtedness outstanding under clause (1), shall not exceed the
      maximum amount permitted under clause (1);

For purposes of determining compliance with this Section 4.10, in the event that
any proposed Indebtedness meets the criteria of more than one of the categories
of Permitted Debt described in clauses (1) through (21) above, or is entitled to
be incurred pursuant to Section 4.10(a), the Issuer will be permitted to
classify such item of Indebtedness on the date of its incurrence, and from time
to time may reclassify, in any manner that complies with this Section 4.10 at
such time. Indebtedness under the Credit Agreement on date of this Indenture
shall be deemed to have been incurred on such date pursuant to Section
4.10(b)(1).

SECTION 4.11. Limitation on Restricted Payments.

            (a) The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly:

            (I) declare or pay any dividend or make any other payment or
      distribution on account of the Issuer's or any of its Restricted
      Subsidiaries' Equity Interests (including, without limitation, any payment
      in connection with any merger or consolidation involving the Issuer or any
      of its Restricted Subsidiaries), other than dividends or distributions
      payable in Equity Interests (other than Disqualified Stock) of the Issuer
      or to the Issuer or a Restricted Subsidiary of the Issuer;

            (II) purchase, redeem or otherwise acquire or retire for value
      (including, without limitation, in connection with any merger or
      consolidation involving the Issuer) any Equity Interests of the Issuer or
      any Parent;

            (III) make any payment of principal or premium on or with respect
      to, or purchase, redeem, defease or otherwise acquire or retire for value,
      any Indebtedness that is subordinated to the Notes or the Note Guarantees
      prior to scheduled maturity, scheduled repayment or scheduled sinking fund
      payment (other than (A) from the Issuer or a Restricted Subsidiary or (B)
      the purchase, repurchase, redemption, defeasance or other acquisition or
      retirement of such subordinated Indebtedness purchased in anticipation of
      satisfying a sinking fund obligation, principal installment or final
      maturity, in each case due within one year of the date of such purchase,
      repurchase, redemption, defeasance or other acquisition or retirement); or

            (IV) make any Restricted Investment (all such payments and other
      actions set forth in clause (I) through (IV) above being collectively
      referred to as "RESTRICTED PAYMENTS"),

            unless, at the time of and after giving effect to such Restricted
      Payment:

            (1) no Default or Event of Default shall have occurred and be
      continuing or would occur as a consequence thereof; and

            (2) the Issuer would, at the time of such Restricted Payment and
      after giving pro forma effect thereto as if such Restricted Payment had
      been made at the beginning of the applicable four-quarter period, have
      been permitted to incur at least $1.00 of addi-

                                      -49-
<PAGE>

      tional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set
      forth in Section 4.10(a); and

            (3) such Restricted Payment, together with the aggregate amount of
      all other Restricted Payments made by the Issuer and its Restricted
      Subsidiaries after the date of this Indenture (excluding Restricted
      Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (9),
      (10), (11), (12), (14), (15) and (16) of Section 4.11(b)), is less than
      the sum, without duplication, of:

                  (a) 50% of the Consolidated Net Income of the Issuer for the
            period (taken as one accounting period) beginning on the date of
            this Indenture and ending on the date of the Issuer's most recently
            ended fiscal quarter for which internal financial statements are
            available at the time of such Restricted Payment (provided, that, if
            the amount of Consolidated Net Income as so calculated divided by
            the number of full fiscal quarters in such period exceeds $5.25
            million, then such amount shall equal (i) 50% of the product of
            $5.25 million multiplied by the number of full fiscal quarters in
            such period plus (ii) 75% of the amount in excess of the product of
            $5.25 million multiplied by the number of full fiscal quarters in
            such period) (or, if such Consolidated Net Income for such period is
            a deficit, less 100% of such deficit); plus

                  (b) 100% of the aggregate net proceeds (including the fair
            market value of property) received by the Issuer subsequent to the
            date of this Indenture as a contribution to its common equity
            capital or from the issue or sale of Equity Interests of the Issuer
            (other than Excluded Contributions or net proceeds from the issue
            and sale of Disqualified Stock) or from the issue or sale of
            convertible or exchangeable Disqualified Stock or convertible or
            exchangeable debt securities of the Issuer that have been converted
            into or exchanged for such Equity Interests (other than Equity
            Interests (or Disqualified Stock or debt securities) sold to a
            Restricted Subsidiary of the Issuer); plus

                  (c) in an amount equal to the net reduction in Investments by
            the Issuer and its Restricted Subsidiaries, subsequent to the date
            of this Indenture, resulting from payments of interests on
            Indebtedness, dividends, repayments of loans or advances or other
            transfers of assets, in each case to the Issuer or any such
            Restricted Subsidiary from any such Investment, or from the net cash
            proceeds from the sale of any such Investment, or from a designation
            of an Unrestricted Subsidiary to a Restricted Subsidiary, but only
            if and to the extent such amounts are not included in the
            calculation of Consolidated Net Income and not to exceed in the case
            of any Investment the amount of the Investment previously made by
            the Issuer or any Restricted Subsidiary in such Person or
            Unrestricted Subsidiary; provided that 50% (or, if subclause (a)(ii)
            of this clause (3) is applicable to the period in which such amounts
            are received, 75%) of amounts in excess of the amount of the
            Investment previously made may be added to the amounts otherwise
            available under this clause (c) to make Restricted Investments
            pursuant to this clause (3).

            (b) Section 4.11(a) will not prohibit:

            (1) the payment of any dividend within 60 days after the date of
      declaration thereof, if at said date of declaration such payment would
      have complied with the provisions of this Indenture;

            (2) the redemption, repurchase, retirement, defeasance or other
      acquisition of any subordinated Indebtedness of the Issuer or any
      Restricted Subsidiary or of any Equity Interests of the Issuer or any
      Parent in exchange for, or out of the net cash proceeds of the
      substantially concurrent sale (other than to a Restricted Subsidiary of
      the Issuer) of, Equity Interests of the Issuer other than Disqualified
      Stock (and any distribution, loan or advance of such net cash proceeds to
      any Parent for such purpose) or out of contributions to the equity capital
      of the Issuer (other than Disqualified Stock); provided that the amount of
      any such net proceeds that are utilized for any such redemption,
      repurchase, retirement, defeasance or other acquisition shall be excluded
      from Section 4.11(a)(3)(b);

      and its Restricted Subsidiaries that occurs after the date of this

the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued to or by the Issuer or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
Section 4.11 shall, if the fair market value thereof exceeds $10.0 million, be
determined by the Board of Directors whose resolution with respect thereto shall
be delivered to the Trustee. The Board of Directors' determination must be based
upon an opinion or appraisal issued by an accounting, appraisal or investment
banking firm of national standing (an "INDEPENDENT FINANCIAL ADVISOR") if the
fair market value exceeds $25.0 million. If any fairness opinion or appraisal is
required by this Indenture in connection with any Restricted Payments, the
Issuer shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment is permitted and setting forth the basis upon which the
calculations required by this Section 4.11 were computed, together with a copy

SECTION 4.12. Limitation on Liens.

            The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien of any kind securing Indebtedness (other than
Permitted Liens) upon any of their property or assets, now owned or hereafter
acquired, unless all payments due under this Indenture and the Notes are secured
on an equal and ratable basis with the obligations so secured (or, in the case
of subordinated Indebtedness, prior or senior thereto, with the same relative
priority as the Notes shall have

                                      -53-
<PAGE>

with respect to such subordinated Indebtedness) until such time as such
obligations are no longer secured by a Lien.

SECTION 4.13. Asset Sales.

            (a) The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

            (1) the Issuer (or such Restricted Subsidiary, as the case may be)
      receives consideration at the time of such Asset Sale at least equal to
      the fair market value of the assets or Equity Interests issued or sold or
      otherwise disposed of;

            (2) in the case of Asset Sales involving consideration in excess of
      $10.0 million, such fair market value is determined by the Issuer's Board
      of Directors and evidenced by a resolution of the Board of Directors set
      forth in an Officers' Certificate delivered to the Trustee; and

            (3) at least 75% of the consideration therefor received by the
      Issuer or such Restricted Subsidiary is in the form of cash, Cash
      Equivalents or Replacement Assets or a combination thereof. For purposes
      of this Section 4.13(a)(3), each of the following shall be deemed to be
      cash:

                  (A) any liabilities (as shown on the Issuer's or such
            Restricted Subsidiary's most recent balance sheet) of the Issuer or
            any Restricted Subsidiary (other than contingent liabilities and
            liabilities that are by their terms subordinated to the Notes or any
            Note Guarantee) that are assumed by the transferee of any such
            assets and, in the case of liabilities other than Non-Recourse Debt,
            where the Issuer and all Restricted Subsidiaries are released from
            any further liability in connection therewith;

                  (B) any securities, notes or other obligations received by the
            Issuer or any such Restricted Subsidiary from such transferee that
            are converted by the Issuer or such Restricted Subsidiary into cash
            within 180 days thereafter (to the extent of the cash received in
            that conversion); and

                  (C) any Designated Noncash Consideration received by the
            Issuer or any of its Restricted Subsidiaries in such Asset Sale
            having an aggregate fair market value (as determined in good faith
            by the Board of Directors of the Issuer), taken together with all
            other Designated Noncash Consideration received pursuant to this
            clause (c) that is at that time outstanding, not to exceed the
            greater of (x) $50.0 million or (y) 5.0% of Consolidated Tangible
            Assets at the time of the receipt of such Designated Noncash
            Consideration (with the fair market value of each item of Designated
            Noncash Consideration being measured at the time received without
            giving effect to subsequent changes in value).

            For purposes of this Section 4.13(a)(3) above, any liabilities of
the Issuer or any Restricted Subsidiary that are not assumed by the transferee
of such assets in respect of which

                                      -54-
<PAGE>

the Issuer and all Restricted Subsidiaries are not released from any future
liabilities in connection therewith shall not be considered consideration.

            (b) Within 365 days after the receipt of any Net Proceeds from an
Asset Sale, the Issuer may apply such Net Proceeds at its option:

            (1) to repay Senior Debt and, if the Senior Debt repaid is revolving
      credit Indebtedness, to correspondingly reduce commitments with respect
      thereto;

            (2) to acquire all or substantially all of the assets of, or a
      majority of the Voting Stock of, another Person engaged in a Permitted
      Business;

            (3) to acquire other assets, including investments in property, or
      to make capital expenditures, that, in either case, are used or useful in
      a Permitted Business; or

            (4) any combination of the foregoing;

provided that the Issuer shall be deemed to have applied Net Proceeds in
accordance with this paragraph within such 365-day period if, within such
365-day period, it has entered into a binding commitment or agreement to invest
such Net Proceeds and continues to use all reasonable efforts to so apply such
Net Proceeds as soon as practicable thereafter but in any event within 180 days
after the end of such 365-day period; provided, further, that upon the earlier
of (x) any abandonment or termination of such commitment or agreement or (y) the
end of such 180-day period, the Net Proceeds not applied will constitute Excess
Proceeds (as defined below).

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

            (c) Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph will constitute "EXCESS
PROCEEDS". When the aggregate amount of Excess Proceeds exceeds $20.0 million,
the Issuer shall make an offer (the "ASSET SALE OFFER") to all Holders of Notes
and all holders of other Indebtedness that is pari passu with the Notes
containing provisions similar to those set forth in this Indenture with respect
to offers to purchase with the proceeds of sales of assets to purchase the
maximum principal amount of Notes and such other pari passu Indebtedness that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale
Offer shall be in an amount equal to 100% of the principal amount of the Notes
plus accrued and unpaid interest to the date of purchase, and will be payable in
cash (the "EXCESS PROCEEDS PAYMENT").

            (d) If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Issuer may use such Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of
Notes and such other pari passu Indebtedness tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds, the Notes and such other pari passu
Indebtedness to be purchased shall be purchased on a pro rata basis based on the
principal amount of Notes and such other pari passu Indebtedness tendered. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds shall be
reset at zero.

                                      -55-
<PAGE>

            (e) To the extent that the aggregate principal amount of the Notes
tendered pursuant to the Asset Sale Offer is less than the Excess Proceeds, the
Issuer may use the remaining Excess Proceeds for general corporate purposes and
such amounts shall no longer be deemed Excess Proceeds. If the aggregate
principal amount of the Notes surrendered by Holders exceeds the amount of
Excess Proceeds available to purchase Notes, the Trustee shall select the Notes
to be purchased on a pro rata basis, subject to the limitation on the authorized
denominations of the Notes.

            (f) Immediately following any Asset Sale Offer, the Issuer is
required to mail a notice to the Trustee and to each Holder stating:

            (i) that the Asset Sale Offer is being made pursuant to this Section
      4.13 and that all Notes tendered will be accepted for payment;

            (ii) the amount of the Excess Proceeds Payment and the purchase date
      (the "EXCESS PROCEEDS PAYMENT DATE"), which may not be earlier than 30
      days nor later than 60 days from the date such notice is mailed;

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

            (iv) that, unless the Issuer defaults in the payment thereof, all
      Notes accepted for payment pursuant to the Asset Sale Offer will cease to
      accrue interest on and after the Excess Proceeds Payment Date;

            (v) that Holders electing to have any Notes purchased pursuant to an
      Asset Sale Offer will be required to surrender the Notes to be purchased
      to the Paying Agent at the address specified in the notice prior to the
      close of business on the third business day preceding the Excess Proceeds
      Payment Date;

            (vi) that Holders will be entitled to withdraw Notes they have
      tendered on the terms and conditions set forth in such notice; and

            (vii)that Holders whose Notes are being purchased only in part will
      be issued new Notes (or book-entry notation made with respect thereto)
      equal in principal amount to the unpurchased portion of the Notes
      tendered; provided that the portion of each Note purchased and each such
      new Note issued (or book-entry notation, if applicable) shall be in a
      principal amount of $1,000 or an integral multiple thereof.

            (g) On the Excess Proceeds Payment Date, the Issuer will, to the
extent lawful:

            (i) accept for payment all Notes or portions thereof tendered
      pursuant to the Asset Sale Offer and not withdrawn;

            (ii) deposit with the Paying Agent an amount sufficient to pay the
      Excess Proceeds Payment in respect of all Notes or portions thereof so
      tendered and not withdrawn; and

                                      -56-
<PAGE>

            (iii)deliver or cause to be delivered to the Trustee all Notes so
      tendered and not withdrawn together with an Officers' Certificate
      specifying the Notes or portions thereof tendered to the Issuer.

            (h) The Paying Agent will promptly mail to each Holder of Notes so
tendered and not withdrawn the Excess Proceeds Payment in respect of such Notes,
and the Trustee will promptly authenticate and mail to such Holder a new Note
(or cause to be transferred by book entry) equal in principal amount to any
unpurchased portion of the Notes surrendered; provided that each such new Note
shall be in a principal amount of $1,000 or an integral multiple thereof. The
Issuer will publicly announce the results of the Asset Sale Offer on or as soon
as practicable after the Excess Proceeds Payment Date.

            (i) The Issuer will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with each
repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with this Section
4.13, the Issuer will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under this Section 4.13
by virtue of complying with such laws and regulations.

SECTION 4.14. Limitation on Transactions with Affiliates.

            The Issuer shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or Guarantee with, or for the benefit
of, any Affiliate involving aggregate consideration in excess of $5.0 million on
or after the Issue Date (each, an "AFFILIATE TRANSACTION"), unless:

            (1) such Affiliate Transaction is on terms that are no less
      favorable to the Issuer or the relevant Restricted Subsidiary than those
      that would have been obtained in a comparable transaction by the Issuer or
      such Restricted Subsidiary with an unrelated Person; and

            (2) the Issuer delivers to the Trustee:

                  (a) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $10.0 million, a resolution of the Board of Directors set
            forth in an Officers' Certificate certifying that such Affiliate
            Transaction complies with this Section 4.14 and that such Affiliate
            Transaction has been approved by a majority of the disinterested
            members of the Board of Directors; and

                  (b) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $25.0 million, an opinion as to the fairness to the Issuer
            or such Restricted Subsidiary of such Af-

                                      -57-
<PAGE>

            filiate Transaction from a financial point of view issued by an
            Independent Financial Advisor.

            The following items shall not be deemed to be Affiliate Transactions
and, therefore, will not be subject to the provisions of the prior paragraph:

            (1) any consulting or employment agreement or arrangement entered
      into by the Issuer or any of its Restricted Subsidiaries approved by a
      majority of the disinterested members of the Board of Directors of the

            (4) issuances and sales of Equity Interests (other than Disqualified
      Stock) to Affiliates of the Issuer;

            (5) any tax sharing agreement or arrangement and payments pursuant
      thereto among the Issuer and its Subsidiaries and any other Person with

      consolidated, combined or unitary tax return or with which the Issuer or
      any of its Restricted Subsidiaries is or could be part of a consolidated,
      combined or unitary group for tax purposes in amounts not otherwise
      prohibited by this Indenture;

            (6) Restricted Payments that are permitted by Section 4.11 or any

      connection with acquisitions or divestitures, which payments are approved
      by the majority of the Board of Directors of the Issuer in good faith;
      provided that the maximum aggregate amount of any such fees in any
      12-month period shall not exceed 1.25% of the aggregate transaction value
      (including enterprise value in connection with acquisitions or
      divestitures) (or portion thereof) in respect of which such services are
      rendered (excluding, in any case, commitment or similar fees for providing

      ordinary course of business;

            (10) agreements (and payments relating thereto) entered into in
      connection with the Stock Purchase Agreement and as described in the
      Offering Memorandum, as the same may be amended, modified or replaced from
      time to time, so long as any amendment, modification or replacement is not

      than the agreement described in the Offering Memorandum and in effect on
      the date of this Indenture;

Subsidiaries.

            (a) The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to:

            (1) pay dividends or make any other distributions on its Capital
      Stock to the Issuer or any of its Restricted Subsidiaries or pay any
      indebtedness owed to the Issuer or any of its Restricted Subsidiaries;

            (2) make loans or advances to the Issuer or any of its Restricted
      Subsidiaries; or

            (3) transfer any of its properties or assets to the Issuer or any of
      its Restricted Subsidiaries.

            (b) However, the preceding restrictions will not apply to
encumbrances or restrictions existing under or by reason of:

            (1) Existing Indebtedness and the Credit Agreement;

                                      -59-

            (2) this Indenture, the Notes and the Note Guarantees or by other
      Indebtedness of the Issuer or of a Guarantor which is pari passu in right
      of payment with the Notes or Note Guarantees, as applicable, incurred
      under an indenture pursuant to Section 4.10; provided that the
      encumbrances and restrictions are no more restrictive, taken as a whole,
      than those contained in this Indenture;

            (3) applicable law or regulation;

            (4) any agreements or instruments governing Indebtedness or Capital
      Stock of a Person acquired by the Issuer or any of its Restricted
      Subsidiaries as in effect at the time of such acquisition (except to the
      extent such Indebtedness or Capital Stock was incurred or issued, as the
      case may be, in connection with or in contemplation of such acquisition),
      which encumbrance or restriction is not applicable to any Person, or the
      properties or assets of any Person, other than the Person, or the property
      or assets of the Person, so acquired; provided that, in the case of
      Indebtedness, such Indebtedness was permitted by the terms of this
      Indenture to be incurred;

            (5) customary non-assignment provisions in leases, licenses and
      other agreements entered into in the ordinary course of business;

            (6) purchase money obligations for property acquired in the ordinary
      course of business that impose restrictions on the property so acquired of
      the nature described in Section 4.15(a)(3);

            (7) an agreement entered into for the sale or disposition of Capital
      Stock or assets of a Restricted Subsidiary or an agreement entered into
      for the sale of specified assets or the granting of an option to purchase
      specified assets (in either case, so long as such encumbrance or
      restriction, by its terms, terminates on the earlier of the termination of
      such agreement or the consummation of such agreement and so long as such
      restriction applies only to the Capital Stock or assets to be sold);

            (8) Permitted Refinancing Indebtedness; provided that the
      encumbrances and restrictions contained in the agreements governing such
      Permitted Refinancing Indebtedness are no more restrictive, taken as a
      whole, than those contained in the agreements governing the Indebtedness
      being refinanced;

            (9) Permitted Liens securing Indebtedness that limit the right of
      the debtor to dispose of the assets subject to such Lien;

            (10) customary limitations on the disposition or distribution of
      assets or property in joint venture agreements and other similar
      agreements entered into in the ordinary course of business;

            (11) any Purchase Money Note, or other Indebtedness or contractual
      requirements of a Receivables Subsidiary in connection with a Qualified
      Securitization Transaction; provided that such restrictions only apply to
      such Receivables Subsidiary;

            (12) cash or other deposits or net worth imposed by customers or

            (14) Indebtedness of a Foreign Subsidiary permitted to be incurred
      under this Indenture; and

            (15) any encumbrances or restrictions imposed by any amendments,
      modifications, restatements, renewals, increases, supplements, refundings,
      replacements or refinancings of the agreements, contracts, instruments or
      obligations referred to in clauses (1) through (14) above; provided that
      such amendments, modifications, restatements, renewals, increases,
      supplements, refundings, replacements or refinancings are, in the good
      faith judgment of the Issuer's Board of Directors, not materially more
      restrictive, taken as a whole, with respect to such dividend and other
      payment restrictions than the dividend or other payment restrictions
      contained in the contracts, agreements, instruments or obligations
      referred to in clauses (1) through (14) above prior to such amendment,
      modification, restatement, renewal, increase, supplement, refunding,
      replacement or refinancing; provided, further, however, that with respect
      to contracts, agreements, instruments or obligations existing on the Issue
      Date, any such amendments, modifications, restatements, renewals,
      increases, supplements, refundings, replacements or refinancings contain,
      in the good faith judgment of the Issuer's Board of Directors, dividend
      and other payment restrictions that are not materially more restrictive,
      taken as a whole, than such restrictions contained in such contracts,
      instruments or obligations as in effect on the Issue Date.

SECTION 4.16. Limitations on Issuances of Guarantees of Indebtedness.

            (a) The Issuer shall not permit any of its Restricted Subsidiaries,
directly or indirectly, to Guarantee or pledge any assets to secure the payment
of any other Indebtedness of the Issuer or any other Restricted Subsidiary
(other than a Guarantee or pledge by a Foreign Restricted Subsidiary securing
the payment of Indebtedness of another Foreign Restricted Subsidiary) unless
either (1) such Restricted Subsidiary is a Guarantor or (2) such Restricted
Subsidiary simultaneously executes and delivers a supplemental indenture in the
form set forth in Exhibit H providing for the Guarantee of the payment of the
Notes by such Restricted Subsidiary, which Guarantee shall be senior to or pari
passu with such Subsidiary's Guarantee of or pledge to secure such other
Indebtedness, unless such other Indebtedness is Senior Debt, in which case the
Guarantee of the Notes may be subordinated to the Guarantee of such Senior Debt,
to the same extent as the Notes are subordinated to such Senior Debt.

            (b) Notwithstanding Section 4.16(a), any Note Guarantee will provide
by its terms that it will be automatically and unconditionally released and
discharged under the circumstances described in Section 11.04.

                                      -61-

SECTION 4.17. Reports.

            (a) Whether or not required by the Commission, so long as any Notes
are outstanding the Issuer will furnish to the Trustee and the nominee of the
Depositary, on behalf of the Holders of Notes, within the time periods specified
in the Commission's rules and regulations:

            (1) all quarterly and annual financial information that would be
      required to be contained in a filing with the Commission on Forms 10-Q and
      10-K if the Issuer were required to file such Forms, including a
      "Management's Discussion and Analysis of Financial Condition and Results
      of Operations" and, with respect to the annual information only, a report
      on the annual financial statements by the Issuer's certified independent
      accountants; and

            (2) all current reports that would be required to be filed with the
      Commission on Form 8-K if the Issuer were required to file such reports;

provided, that if the Issuer files such reports electronically with the
Commission's Electronic Data Gathering Analysis and Retrieval System (or any
successor system) within such time periods, the Issuer shall not be required
under this Indenture to furnish such reports as specified above.

            (b) In addition, following the date by which the Issuer is required
to consummate the exchange offer contemplated by the Registration Rights
Agreement, whether or not required by the Commission, the Issuer will file a
copy of all of the information and reports referred to in Sections 4.17(a)(1)
and (2) with the Commission for public availability within the time periods
specified in the Commission's rules and regulations (unless the Commission will
not accept such a filing) and make such information available to securities
analysts and prospective investors upon request. In addition, the Issuer and the
Guarantors have agreed that, for so long as any Notes (but not the Exchange
Notes) remain outstanding, they will furnish to the Holders and to securities
analysts and prospective investors, upon their request, the information required
to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

            (c) In addition, if at any time Parent becomes a Guarantor (there
being no obligation of Parent to do so), holds no material assets other than
cash, Cash Equivalents and the Capital Stock of the Issuer or any direct or
indirect parent of the Issuer (and performs the related incidental activities
associated with such ownership) and complies with the requirements of Rule 3-10
of Regulation S-X promulgated by the Commission (or any successor provision),
the reports, information and other documents required to be filed and furnished
to holders of the Notes pursuant to this Section 4.17 may, at the option of the
Issuer, be filed by and be those of any Parent rather than the Issuer.

            (d) Notwithstanding the foregoing, such requirements shall be deemed
satisfied with respect to the furnishing of a Form 10-K for the Issuer's fiscal
year 2004 by the filing with the Commission of the Exchange Offer Registration
Statement (as defined in the Registration Rights Agreement), and any amendments
thereto, with such financial information that satisfies Regulation S-X of the
Securities Act with respect to fiscal year 2004.

                                      -62-
<PAGE>

            The Trustee shall not be under a duty to review or evaluate any
report or information delivered to the Trustee pursuant to the provisions of
this Section 4.17 for the purposes of making such reports available to it and to
the Holders of the Notes who may request such information. Delivery of such
reports, information and documents to the Trustee as may be required under this
Section 4.17 is for informational purposes only and the Trustee's receipt of
such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Issuer's compliance with any of its covenants hereunder (as to which the Trustee
is entitled to rely exclusively on an Officers' Certificate).

SECTION 4.18. Payments for Consent.

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

SECTION 4.19. Limitation on Senior Subordinated Debt.

            The Issuer shall not incur, create, issue, assume, Guarantee or
otherwise become liable for any Indebtedness that is contractually subordinate
or junior in right of payment to any Senior Debt of the Issuer and senior in
right of payment to the Notes. No Guarantor will incur, create, issue, assume,
Guarantee or otherwise become liable for any Indebtedness that is contractually
subordinate or junior in right of payment to the Senior Debt of such Guarantor
and senior in right of payment to such Guarantor's Note Guarantee. For purposes
of the foregoing, no Indebtedness will be deemed to be contractually
subordinated or junior in the right of payment to any Indebtedness solely by
virtue of being unsecured or by virtue of the fact that the holder of secured
Indebtedness have entered into intercreditor or similar arrangements giving one
or more of such holders priority over the other holders in the collateral held
by them.

SECTION 4.20. Additional Note Guarantees.

            If on or after the date of this Indenture the Issuer or any of its
Restricted Subsidiaries acquires or creates another Domestic Subsidiary (other
than a Receivables Subsidiary) that Guarantees any Indebtedness of the Issuer or
any Restricted Subsidiary, then that newly acquired or created Domestic
Subsidiary (other than an Immaterial Subsidiary) must become a Guarantor and
execute a supplemental indenture in the form set forth in Exhibit H hereto and
deliver an Opinion of Counsel to the Trustee within 20 Business Days of the date
on which it was acquired or created. At the Issuer's option, the Issuer may
cause any Foreign Restricted Subsidiary to Guarantee the Notes.

SECTION 4.21. Designation of Restricted and Unrestricted Subsidiaries.

            The Board of Directors of the Issuer may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause
a Default; provided that in no event shall there be any Unrestricted
Subsidiaries on or immediately following the date of this

                                      -63-
<PAGE>

Indenture. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate fair market value of all outstanding Investments owned
by the Issuer and its Restricted Subsidiaries in the Subsidiary so designated
(after giving effect to any sale of Equity Interests of such Subsidiary in
connection with such designation) will be deemed to be an Investment made as of
the time of such designation and will either reduce the amount available for
Restricted Payments under Section 4.11(a) or reduce the amount available for
future Investments under one or more clauses of the definition of "Permitted
Investments." That designation shall only be permitted if such Investment would
be permitted at that time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Board of Directors of the Issuer
may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that such designation shall be deemed to be an incurrence
of Indebtedness by a Restricted Subsidiary of the Issuer of any outstanding
Indebtedness of such Unrestricted Subsidiary and such designation shall only be
permitted if (1) such Indebtedness is permitted under Section 4.10, calculated
on a pro forma basis as if such designation had occurred at the beginning of the
four-quarter reference period; and (2) no Default or Event of Default would be
in existence following such designation.

SECTION 4.22. Business Activities.

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

                              SUCCESSOR CORPORATION

SECTION 5.01. Merger, Consolidation, or Sale of Assets.

            (a) The Issuer shall not, directly or indirectly, consolidate or
merge with or into another Person (whether or not the Issuer is the surviving
corporation), and the Issuer will not sell, assign, transfer, convey or
otherwise dispose of all or substantially all of the properties or assets of the
Issuer and its Restricted Subsidiaries taken as a whole, in one or more related
transactions, to another Person (including by way of consolidation or merger),
unless:

            (1) either: (A) the Issuer is the surviving corporation or (B) the
      Person formed by or surviving any such consolidation or merger (if other
      than the Issuer) or to which such sale, assignment, transfer, conveyance
      or other disposition shall have been made is a corporation, partnership or
      limited liability company organized or existing under the laws of the
      United States, any state thereof or the District of Columbia; provided
      that, in the case such Person is a limited liability company or a
      partnership, a co-obligor of the Notes is a corporation;

            (2) the Person formed by or surviving any such consolidation or
      merger (if other than the Issuer) or the Person to which such sale,
      assignment, transfer, conveyance or other disposition shall have been made
      assumes all the obligations of the Issuer, as the case may be, under the
      Notes, this Indenture and the Registration Rights Agreement pursuant to
      agreements reasonably satisfactory to the Trustee;

                                      -64-
<PAGE>

            (3) immediately after such transaction and any related financing
      transactions, no Default or Event of Default exists; and

            (4) the Issuer or the Person formed by or surviving any such
      consolidation or merger (if other than the Issuer), or to which such sale,
      assignment, transfer, conveyance or other disposition shall have been
      made, on the date of such transaction after giving pro forma effect
      thereto and any related financing transactions as if the same had occurred
      at the beginning of the applicable four-quarter period either (A) would be
      permitted to incur at least $1.00 of additional Indebtedness pursuant to
      the Fixed Charge Coverage Ratio test set forth in Section 4.10(a), or (B)
      would have a Fixed Charge Coverage Ratio on such basis higher than the
      Fixed Charge Coverage Ratio immediately prior to such transactions.

            (b) Notwithstanding clauses (3) and (4) of Section 5.01(a), the
Issuer may merge or consolidate with a Restricted Subsidiary incorporated solely
for the purposes of organizing the Issuer in another jurisdiction.

            (c) The Issuer shall not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person.

            (d) This Section 5.01 will not apply to (i) a sale, assignment,
transfer, conveyance or other disposition of assets (including by way of
consolidation or merger) between or among the Issuer and any of its Restricted
Subsidiaries or (ii) the Transactions.

            (e) In connection with any such consolidation, merger, sale,
assignment, transfer, conveyance or other disposition, the Issuer shall deliver,
or cause to be delivered, to the Trustee, in form and substance reasonably
satisfactory to the Trustee, an Officers' Certificate and an Opinion of Counsel,
each stating that such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition and the supplemental indenture in respect
thereto comply with this Indenture and that all conditions precedent therein
provided for relating to such transactions have been complied with.

            (f) Upon any such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition, the successor Person formed by such
consolidation or into which the Issuer is merged or the successor Person to
which such transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Issuer under this Indenture with the same
effect as if such successor Person had been named as the Issuer in this
Indenture, and when a successor Person assumes all the obligations of its
predecessor under this Indenture or the Notes, the predecessor shall be released
from those obligations; provided, however, that in the case of a transfer by
lease, the predecessor shall not be released from the payment of principal of,
premium, if any, and interest on the Notes.

                              DEFAULT AND REMEDIES

SECTION 6.01. Events of Default.

            Each of the following constitutes an "EVENT OF DEFAULT":

            (1) the Issuer defaults for 30 days in the payment when due of
      interest on the Notes whether or not prohibited by Article X;

            (2) the Issuer defaults in payment when due of the principal of, or
      premium, if any, on the Notes, whether or not prohibited by Article X;

            (3) failure by the Issuer or any of its Restricted Subsidiaries to
      comply with Section 4.09, Section 4.13 or Section 5.01;

            (4) failure by the Issuer or any of its Restricted Subsidiaries for
      45 days after notice by the Trustee or by Holders of at least 25% in
      principal amount of the then outstanding Notes to comply with any of the
      other agreements in this Indenture;

            (5) default by the Issuer or any Restricted Subsidiary under any
      mortgage, indenture or instrument under which there may be issued or by
      which there may be secured or evidenced any Indebtedness for money
      borrowed by the Issuer or any of its Restricted Subsidiaries (or the
      payment of which is Guaranteed by the Issuer or any of its Restricted
      Subsidiaries) whether such Indebtedness or Guarantee now exists, or is
      created after the date of this Indenture, if that default:

                  (a) is caused by a failure to make any payment when due at the
            final maturity (after any applicable grace period) of such
            Indebtedness (a "PAYMENT DEFAULT"); or

                  (b) results in the acceleration of such Indebtedness prior to
            its express maturity;

      and, in each case, the principal amount of any such Indebtedness, together
      with the principal amount of any other such Indebtedness under which there
      has been a Payment Default or the maturity of which has been so
      accelerated, aggregates $25.0 million or more;

            (6) failure by the Issuer or any of its Restricted Subsidiaries to
      pay final judgments aggregating in excess of $25.0 million (net of any
      amount covered by insurance), which judgments are not paid, discharged or
      stayed for a period of 60 days after such judgments have become final and
      non-appealable and, in the event such judgment is covered by insurance, an
      enforcement proceeding has been commenced by any creditor upon such
      judgment or decree that is not promptly stayed;

                                      -66-
<PAGE>

            (7) except as permitted by this Indenture, any Note Guarantee of a
      Guarantor that is a Significant Subsidiary, or the Note Guarantees of any
      group of Guarantors that, taken together, would constitute a Significant
      Subsidiary, shall be held in any judicial proceeding to be unenforceable
      or invalid or shall cease for any reason to be in full force and effect or
      any such Guarantor or group of Guarantors, or any Person acting on behalf
      of any such Guarantor or group of Guarantors, shall deny or disaffirm its
      obligations under its Note Guarantee; and

            (8) the Issuer or any of its Significant Subsidiaries or any group
      of Restricted Subsidiaries that, taken together, would constitute a
      Significant Subsidiary, pursuant to or within the meaning of Bankruptcy
      Law:

                  (i) commences a voluntary case; or

                  (ii) consents to entry of an order for relief against it in an
            involuntary case; or

                  (iii) consents to the appointment of a custodian of it or for
            all or substantially all of its property; or

                  (iv) makes a general assignment for the benefit of its
            creditors; or

                  (v) generally is not paying its debts as they become due; or

            (9) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                  (i) is for relief against any Guarantor, the Issuer or any of
            its Subsidiaries that is a Significant Subsidiary or any group of
            Subsidiaries that, taken as a whole, would constitute a Significant
            Subsidiary in an involuntary case;

                  (ii) appoints a custodian of any Guarantor, the Issuer or any
            of its Subsidiaries that is a Significant Subsidiary or any group of
            Subsidiaries that, taken as a whole, would constitute a Significant
            Subsidiary or for all or substantially all of the property of any
            Guarantor, the Issuer or any of its Subsidiaries that is a
            Significant Subsidiary or any group of Subsidiaries that, take as a
            whole, would constitute a Significant Subsidiary; or

                  (iii) orders the liquidation of any Guarantor, the Issuer or
            any of its Subsidiaries that is a Significant Subsidiary or any
            group of Subsidiaries that, taken as a whole, would constitute a
            Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days;

            In the event of a declaration of acceleration of the Notes because
an Event of Default has occurred and is continuing as a result of the
acceleration of any Indebtedness described in clause (5) of the preceding
paragraph, the declaration of acceleration of the Notes shall be

                                      -67-
<PAGE>

automatically annulled if the holders of any Indebtedness described in clause
(5) of the preceding paragraph have rescinded the declaration of acceleration in
respect of such Indebtedness within 30 days of the date of such declaration and
if (i) the annulment of the acceleration of Notes would not conflict with any
judgment or decree of a court of competent jurisdiction and (ii) all existing
Events of Default, except nonpayment of principal or interest on the Notes that
became due solely because of the acceleration of the Notes have been cured or
waived.

SECTION 6.02. Acceleration.

            In the case of any Event of Default specified in Section 6.01(8) or
(9) that occurs and is continuing, then all unpaid principal of, premium, if
any, and accrued and unpaid interest, if any, on all of the outstanding Notes
shall ipso facto become due and payable immediately without further action or
notice on the part of the Trustee or any Holder.

            If any Event of Default (other than an Event of Default specified in
Section 6.01(8) or (9)) occurs and is continuing, the Trustee or the Holders of
at least 25% in principal amount of the then outstanding Notes may declare all
unpaid principal of, premium, if any, and accrued interest on the Notes to be
due and payable immediately by notice in writing in writing to the Issuer
specifying the respective Event of Default; provided, however, that so long as
any Indebtedness permitted to be incurred pursuant to the Credit Agreement shall
be outstanding, that acceleration shall not be effective until the earlier of
(1) an acceleration of Indebtedness under the Credit Agreement; or (2) five
Business Days after receipt by the Issuer and the Agent under Credit Agreement
of written notice of the acceleration of the Notes.

SECTION 6.03. Other Remedies.

            (a) If a Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of, premium, if any, or interest on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

            (b) The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Noteholder in exercising any right or
remedy accruing upon a Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Default. No remedy is exclusive of
any other remedy. All available remedies are cumulative to the extent permitted
by law.

            (c) Holders may not enforce this Indenture or the Notes except as
provided in this Indenture and under the TIA. Subject to the provisions of this
Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under this Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity. The Trustee may withhold from
Holders of the Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal,
premium, if any, or interest) if it determines that withholding notice is in
their interest. Subject to all provisions of this Indenture and applicable law,
the Holders of a majority in aggregate principal amount of the then outstanding
Notes issued under this Indenture have the right to direct the time, method and
place of conducting any proceeding

                                      -68-
<PAGE>

for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee.

SECTION 6.04. Waiver of Defaults.

            Provided the Notes are not then due and payable by reason of a
declaration of acceleration, the Holders of a majority in aggregate principal
amount of the Notes at the time outstanding may on behalf of the Holders of all
the Notes waive any Default with respect to such Notes and its consequences by
providing written notice thereof to the Issuer and the Trustee, except a Default
(1) in the payment of the principal of, premium, if any, or interest on any Note
or (2) in respect of a covenant or provision hereof which under this Indenture
cannot be modified or amended without the consent of the Holder of each
outstanding Note affected. In the case of any such waiver, the Issuer, the
Trustee and the Holders will be restored to their former positions and rights
under this Indenture, respectively; provided that no such waiver shall extend to
any subsequent or other Default or impair any right consequent thereto.

SECTION 6.05. Control by Majority.

            The Holders of not less than a majority in principal amount of the
outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. Subject to Section 7.01, however, the Trustee may refuse
to follow any direction that conflicts with any law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another
Noteholder, or that may involve the Trustee in personal liability; provided that
the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

            In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
against any loss or expense caused by taking such action or following such
direction.

SECTION 6.06. Limitation on Suits.

            A Holder may not pursue any remedy with respect to this Indenture or
the Notes unless:

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

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

            (3) such Holder or Holders offer and provide to the Trustee
      reasonable indemnity or security against any loss, liability or expense
      satisfactory to the Trustee;

            (4) the Trustee does not comply with the request within 30 days
      after receipt of the request and the offer of indemnity and security; and

                                      -69-
<PAGE>

            (5) during such 30-day period the Holder or Holders of a majority in
      principal amount of the outstanding Notes do not give the Trustee a
      direction which, in the opinion of the Trustee, is inconsistent with the
      request.

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

SECTION 6.07. Rights of Holders To Receive Payment.

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

SECTION 6.08. Collection Suit by Trustee.

            If a Default in payment of principal or interest specified in
Section 6.01(1) occurs and is continuing, the Trustee may recover judgment in
its own name and as trustee of an express trust against the Issuer or any other
obligor on the Notes for the whole amount of the principal of, premium, if any,
and accrued interest on the Notes and fees remaining unpaid, together with
interest on overdue principal and premium, if any, and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate per annum borne by the Notes and such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim.

            The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel) and the Holders allowed in any
judicial proceedings relating to the Issuer, its creditors or its property and
shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same,
and any Custodian in any such judicial proceedings is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it for the compensation, expenses, disbursements
and advances of the Trustee, its agent and counsel, and any other amounts due
the Trustee under Section 7.07. Nothing herein contained shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of
any 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.
The Trustee shall be entitled to participate as a member of any officer
committee of creditors in the matters as it deems necessary or advisable.

                                      -70-

SECTION 6.10. Priorities.

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

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

            SECOND: to Holders for interest accrued on the Notes, ratably,
      without preference or priority of any kind, according to the amounts due
      and payable on the Notes for interest;

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

            FOURTH: to the Issuer.

            The Trustee, upon prior notice to the Issuer, may fix a Record Date
and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs.

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

                                   ARTICLE VII

                                     TRUSTEE

SECTION 7.01. Duties of Trustee.

            (a) If a 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 a Default:

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

                                      -71-
<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 (including Officers'
      Certificates) or opinions (including Opinions of Counsel) 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.

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

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

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

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

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

            (e) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to this Section
7.01.

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

            (g) In the absence of bad faith, negligence or willful misconduct on
the part of the Trustee, the Trustee shall not be responsible for the
application of any money by any Paying Agent other than the Trustee.

SECTION 7.02. Rights of Trustee.

            Subject to Section 7.01:

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

            (b) Before the Trustee acts or refrains from acting, it may require
      an Officers' Certificate and an Opinion of Counsel, which shall conform to
      the provisions of Section 12.05. The Trustee shall not be liable for any
      action it takes or omits to take in good faith in reliance on such
      certificate or opinion.

            (c) The Trustee may act through its attorneys and agents and shall
      not be responsible for the misconduct or negligence of any agent (other
      than an agent who is an employee of the Trustee) appointed with due care.

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

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

            (f) 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 satisfactory to it against the costs,
      expenses and liabilities which may be incurred therein or thereby.

            (g) The Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate (including any
      Officers' Certificate), statement, instrument, opinion (including any
      Opinion of Counsel), notice, request, direction, consent, order, bond,
      debenture, or other paper or document.

            (h) The Trustee shall not be required to give any bond or surety in
      respect of the performance of its powers and duties hereunder.

            (i) The permissive rights of the Trustee to do things enumerated in
      this Indenture shall not be construed as duties.

            (j) The Trustee shall not be deemed to have notice of any Default
      unless a Responsible Officer of the Trustee has actual knowledge thereof
      or unless written notice of any event which is in fact such a default is
      received by the Trustee at the Corporate Trust Office of the Trustee, and
      such notice references the Notes and this Indenture.

                                      -73-
<PAGE>

            (k) The rights, privileges, protections, immunities and benefits
      given to the Trustee, including, without limitation, its right to be
      indemnified, are extended to, and shall be enforceable by, the Trustee in
      each of its capacities hereunder, and to each agent, custodian and other
      Person employed to act hereunder.

SECTION 7.03. Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of the Notes and may otherwise deal with the Issuer, its
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.

SECTION 7.04. Trustee's Disclaimer.

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

SECTION 7.05. Notice of Default.

            If a Default occurs and is continuing and the Trustee receives
actual notice of such Default, the Trustee shall mail to each Holder notice of
the uncured Default within 60 days after such notice is received. Except in the
case of a Default in payment of the principal of, premium, if any, or interest
on, any Note, including an accelerated payment and the failure to make payment
on the Change of Control Payment Date pursuant to a Change of Control Offer or
the Excess Proceeds Payment Date pursuant to an Asset Sale Offer, the Trustee
may withhold the notice if and so long as the Board of Directors, the executive
committee, or a trust committee of directors and/or Responsible Officers, of the
Trustee in good faith determines that withholding the notice is in the interest
of the Holders.

SECTION 7.06. Reports by Trustee to Holders.

            Within 60 days after each June 30, beginning with June 30, 2005, the
Trustee shall, to the extent that any of the events described in TIA Section
313(a) occurred within the previous twelve months, but not otherwise, mail to
each Holder a brief report dated as of such date that complies with TIA Section
313(a). The Trustee also shall comply with TIA Sections 313(b), 313(c) and
313(d).

            A copy of each report at the time of its mailing to Holders shall be
mailed to the Issuer and filed with the Commission and each securities exchange,
if any, on which the Notes are listed.

            The Issuer shall notify the Trustee if the Notes become listed on
any securities exchange or of any delisting thereof and the Trustee shall comply
with TIA Section 313(d).

                                      -74-
<PAGE>

SECTION 7.07. Compensation and Indemnity.

            The Issuer shall pay to the Trustee from time to time such
compensation as the Issuer and the Trustee shall from time to time agree in
writing for its services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall reimburse the Trustee upon request for all reasonable disbursements,
expenses and advances (including reasonable fees and expenses of counsel)
incurred or made by it in addition to the compensation for its services, except
any such disbursements, expenses and advances as may be attributable to the
Trustee's negligence, bad faith or willful misconduct. Such expenses shall
include the reasonable fees and expenses of the Trustee's agents and counsel.

            The Issuer shall indemnify each of the Trustee or any predecessor
Trustee and its agents, employees, officers, stockholders and directors for, and
hold them harmless against, any and all loss, damage, claims including taxes
(other than taxes based upon, measured by or determined by the income of the
Trustee), liability or expense incurred by them except for such actions to the
extent caused by any negligence, bad faith or willful misconduct on their part,
arising out of or in connection with the acceptance or administration of this
trust including the reasonable costs and expenses of defending themselves
against or investigating any claim or liability in connection with the exercise
or performance of any of the Trustee's rights, powers or duties hereunder. The
Trustee shall notify the Issuer promptly of any claim asserted against the
Trustee or any of its agents, employees, officers, stockholders and directors
for which it may seek indemnity. The Issuer may, subject to the approval of the
Trustee (which approval shall not be unreasonably withheld), defend the claim
and the Trustee shall cooperate in the defense. The Trustee and its agents,
employees, officers, stockholders and directors subject to the claim may have
separate counsel and the Issuer shall pay the reasonable fees and expenses of
such counsel; provided, however, that the Issuer will not be required to pay
such fees and expenses if, subject to the approval of the Trustee (which
approval shall not be unreasonably withheld), it assumes the Trustee's defense
and there is no conflict of interest between the Issuer and the Trustee and its
agents, employees, officers, stockholders and directors subject to the claim in
connection with such defense as reasonably determined by the Trustee. The Issuer
need not pay for any settlement made without its written consent. The Issuer
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 Issuer's payment obligations in this Section 7.07, the
Trustee shall have a senior lien prior to the Notes against all money or
property held or collected by the Trustee, in its capacity as Trustee.

            Without prejudice to its rights hereunder, when the Trustee incurs
expenses or renders services after a Default specified in Section 6.01(8) or (9)
occurs, such expenses and the compensation for such services (including the fees
and expenses of its agent and counsel) shall constitute expenses of
administration under the Bankruptcy Law.

            Notwithstanding any other provision in this Indenture, the foregoing
provisions of this Section 7.07 shall survive the satisfaction and discharge of
this Indenture or the appointment of a successor Trustee.

                                      -75-
<PAGE>

SECTION 7.08. Replacement of Trustee.

            The Trustee may resign at any time by providing thirty days prior
written notice to the Issuer. The Holders of a majority in principal amount of
the outstanding Notes may remove the Trustee by so notifying the Issuer and the
Trustee and may appoint a successor Trustee. The Issuer may remove the Trustee
if:

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

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

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

            (4) 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 Issuer shall notify each Holder of such
event and shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuer.

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.07, the resignation
or removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Holder. A resignation of the Trustee shall not be effective until a successor
trustee delivers a written acceptance of its appointment in accordance with this
Section 7.08.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the
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 at the expense of the Issuer.

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

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

SECTION 7.09. Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, 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; provided that such
corporation shall be otherwise qualified and eligible under this Article VII.

SECTION 7.10. Eligibility; Disqualification.

            This Indenture shall always have a Trustee who satisfies the
requirement of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee
shall have a combined capital and surplus of at least $150,000,000 as set forth
in its most recent published annual report of condition. In addition, if the
Trustee is a corporation included in a bank holding company system, the Trustee,
independently of the bank holding company, shall meet the capital requirements
of TIA Section 310(a)(2). The Trustee shall comply with TIA Section 310(b);
provided, however, that there shall be excluded from the operation of TIA
Section 310(b)(1) any indenture or indentures under which other securities, or
certificates of interest or participation in other securities, of the Issuer are
outstanding, if the requirements for such exclusion set forth in TIA Section
310(b)(1) are met. The provisions of TIA Section 310 shall apply to the Issuer
and any other obligor of the Notes.

SECTION 7.11. Preferential Collection of Claims Against the Issuer.

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

                                  ARTICLE VIII

                       DISCHARGE OF INDENTURE; DEFEASANCE

SECTION 8.01. Termination of the Issuer's Obligations.

            (a) This Indenture will be discharged and will cease to be of
further effect as to all Notes issued thereunder, except those obligations
referred to in the penultimate paragraph of this Section 8.01, when the Issuer
or any Guarantor has paid or caused to be paid all sums payable by it under this
Indenture and, either:

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

                  (2) (A) all Notes that have not been delivered to the Trustee
            for cancellation have become due and payable by reason of the making
            of a notice of redemption or otherwise or will become due and

            as a result of a redemption notice properly given pursuant to this
            Indenture, and the Issuer or any Guarantor has irrevocably deposited
            or caused to be deposited with the Trustee as trust funds in trust
            solely for the benefit of the Holders, cash in U.S. Legal Tender,
            non-callable Government Securities, or a combination thereof, in
            such amounts as will be sufficient without consideration of any
            reinvestment of interest, to pay and discharge the entire
            indebtedness on the Notes not delivered to the Trustee for
            cancellation for principal, premium, if any, and accrued interest to
            the date of maturity or redemption; (B) no Default or Event of
            Default shall have occurred and be continuing on the date of such
            deposit or shall occur as a result of such deposit and such deposit
            will not result in a breach or violation of, or constitute a default
            under, any other instrument to which the Issuer or any Guarantor is
            a party or by which the Issuer or any Guarantor is bound; and (C)
            the Issuer has delivered irrevocable instructions to the Trustee
            under this Indenture to apply the deposited money toward the payment
            of the Notes at maturity or on the Redemption Date, as the case may
            be.

            (b) In addition, the Issuer shall deliver to the Trustee an
      Officers' Certificate and an Opinion of Counsel, each stating that all
      conditions precedent providing for or relating to the termination of the
      Issuer's obligations under the Notes and this Indenture have been complied
      with.

            Subject to the next sentence and notwithstanding the foregoing
paragraph, the Issuer's obligations in Sections 2.06, 2.07, 2.08, 2.09, 4.02,
7.07, 8.05 and 8.06 shall survive until the Notes are no longer outstanding
pursuant to the last paragraph of Section 2.09. After the Notes are no longer
outstanding, the Issuer's obligations in Sections 7.07, 8.05 and 8.06 shall
survive.

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

SECTION 8.02. Legal Defeasance and Covenant Defeasance.

            (a) The Issuer may, at its option and at any time, elect to have
either paragraph (b) or (c) below be applied to all outstanding Notes upon
compliance with the conditions set forth in Section 8.03.

            (b) Upon the Issuer's exercise under paragraph (a) hereof of the
option applicable to this paragraph (b), the Issuer shall, subject to the
satisfaction of the conditions set forth in Section 8.03, be deemed to have been
discharged from its obligations with respect to all outstanding Notes on the
date the conditions set forth below are satisfied (hereinafter, "LEGAL
DEFEASANCE"). For this purpose, Legal Defeasance means that the Issuer shall be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be "outstanding" only for
the purposes of Section 8.04 hereof and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of
and at the expense of the Issuer, shall execute proper instruments acknowledging
the

                                      -78-
<PAGE>

same), except for the following provisions which shall survive until otherwise
terminated or discharged hereunder:

            (1) the rights of Holders of outstanding Notes to receive payments
      in respect of the principal of, or interest or premium, if any, on such
      Notes when such payments are due from the trust referred to below;

            (2) the Issuer's obligations under Sections 2.06, 2.07, 2.08, 2.09
      and 4.02;

            (3) the rights, powers, trusts, duties and immunities of the
      Trustee, and the Issuer's and the Guarantors' obligations in connection
      therewith; and

            (4) this Article VIII.

            Subject to compliance with this Article VIII, the Issuer may
exercise its option under this Section 8.02(b) notwithstanding the prior
exercise of its option under Section 8.02(c) hereof.

            (c) Upon the Issuer's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), the Issuer shall, subject to the
satisfaction of the conditions set forth in Section 8.03 hereof, be released
from its obligations under the covenants contained in Sections 4.04, 4.05, 4.07,
4.09 through 4.22 and clauses (3) and (4) of Section 5.01(a) hereof with respect
to the outstanding Notes on and after the date the conditions set forth in
Section 8.03 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 (it being understood that such
Notes shall not be deemed outstanding for accounting purposes). For this
purpose, Covenant Defeasance means that, with respect to the outstanding Notes,
the Issuer may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such covenant, whether directly
or indirectly, by reason of any reference elsewhere herein to any such covenant
or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not constitute an
Event of Default under Section 6.01 hereof, but, except as specified above, the
remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Issuer's exercise under paragraph (a) hereof of the option
applicable to this paragraph (c), subject to the satisfaction of the conditions
set forth in Section 8.03 hereof, clauses (3), (5) and (6) of Section 6.01
hereof shall not constitute Events of Default.

SECTION 8.03. Conditions to Legal Defeasance or Covenant Defeasance.

            The following shall be the conditions to the application of either
Section 8.02(b) or 8.02(c) hereof to the outstanding Notes:

                                      -79-
<PAGE>

            In order to exercise either Legal Defeasance or Covenant Defeasance:

            (1) the Issuer must irrevocably deposit with the Trustee, in trust,
      for the benefit of the Holders of the Notes, cash in U.S. Legal Tender,
      non-callable Government Securities, 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, or
      interest and premium, if any, on the outstanding Notes on the Stated
      Maturity or on the applicable Redemption Date, as the case may be, and the
      Issuer must specify whether the Notes are being defeased to maturity or to
      a particular Redemption Date;

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

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

            (4) no Default or Event of Default shall have occurred and be
      continuing on the date of such deposit (other than a Default or Event of
      Default resulting from the borrowing of funds to be applied to such
      deposit and the grant of any Lien securing such borrowing);

            (5) such Legal Defeasance or Covenant Defeasance will not result in
      a breach or violation of, or constitute a default under any material
      agreement or instrument to which the Issuer or any of its Subsidiaries is
      a party or by which the Issuer or any of its Subsidiaries is bound;

            (6) the Issuer must deliver to the Trustee an Officers' Certificate
      stating that the deposit was not made by the Issuer with the intent of
      preferring the Holders of Notes over the other creditors of the Issuer
      with the intent of defeating, hindering, delaying or defrauding creditors
      of the Issuer or others; and

            (7) the Issuer must deliver to the Trustee an Officers' Certificate
      and an Opinion of Counsel, each stating that all conditions precedent
      relating to the Legal Defeasance or the Covenant Defeasance have been
      complied with.

                                      -80-

SECTION 8.04. Application of Trust Money.

            The Trustee or Paying Agent shall hold in trust U.S. Legal Tender
and Government Securities deposited with it pursuant to this Article VIII, and
shall apply the deposited U.S. Legal Tender and the money from Government
Securities in accordance with this Indenture to the payment of the principal of,
premium, if any, and interest, on the Notes. The Trustee shall be under no
obligation to invest said U.S. Legal Tender and Government Securities except as
it may agree with the Issuer.

            The Issuer shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Legal Tender and
Government Securities deposited pursuant to Section 8.03 or the principal,
premium, if any, and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the
outstanding Notes.

            Anything in this Article VIII to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuer from time to time upon the Issuer's
request any U.S. Legal Tender and Government Securities held by it as provided
in Section 8.03 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

SECTION 8.05. Repayment to the Issuer.

            Subject to this Article VIII, the Trustee and the Paying Agent shall
promptly pay to the Issuer upon request any excess U.S. Legal Tender and
Government Securities held by them at any time and thereupon shall be relieved
from all liability with respect to such money. The Trustee and the Paying Agent
shall pay to the Issuer upon request any money held by them for the payment of
the principal of, premium, if any, or interest that remains unclaimed for two
years; provided that the Trustee or such Paying Agent, before being required to
make any payment, may at the expense of the Issuer cause to be published once in
a newspaper of general circulation in the City of New York or mail to each
Holder entitled to such money notice that such money remains unclaimed and that
after a date specified therein which shall be at least 30 days from the date of
such publication or mailing any unclaimed balance of such money then remaining
will be repaid to the Issuer. After payment to the Issuer, Holders entitled to
such money must look to the Issuer for payment as general creditors unless an
applicable law designates another Person.

SECTION 8.06. Reinstatement.

            If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender and Government Securities in accordance with this Article VIII by reason
of any legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Issuer's obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to this
Article VIII until such time as the Trustee or Paying Agent is permitted to
apply all such U.S. Legal Tender and Government Securities in accordance with
this Article VIII; provided that if the Is-

                                      -81-
<PAGE>

suer has made any payment of interest on or principal of any Notes because of
the reinstatement of its obligations, the Issuer shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the U.S. Legal
Tender and Government Securities held by the Trustee or Paying Agent.

      benefits to the Holders of Notes or that does not adversely affect in any
      material respect the legal rights under this Indenture of any such Holder;

            (5) to comply with requirements of the Commission in order to effect
      or maintain the qualification of this Indenture under the Trust Indenture
      Act;

            (6) to provide for the issuance of Additional Notes in accordance
      with this Indenture;

      depositary; or

      of this Indenture or to otherwise comply with any requirement of this
      Indenture;

provided that the Issuer has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.01.

SECTION 9.02. With Consent of Holders.

            (a) Subject to Sections 6.04 and 6.07, the Issuer and the Trustee,
together, with the written consent of the Holder or Holders of a majority in
aggregate principal amount of the outstanding Notes (which may include consents
obtained in connection with a tender offer or exchange offer for the Notes), may
amend or supplement this Indenture or the Notes or may waive compliance by the
Issuer or any Subsidiary Guarantor with any provision of this Indenture, the
Notes or such Subsidiary Guarantor's Subsidiary Guaranty. Without the consent of

or waiver of, the provisions of this Indenture may make any change in the
provisions of Article X hereof that adversely affects the rights of any Holder
of Notes. Furthermore, neither Article VIII nor Article X shall be amended or
modified in a manner that adversely affects the rights of the holders of Senior
Debt under the Credit Agreement without the consent of the requisite holders of
such Senior Debt (or their Representative). Section 2.08 hereof shall determine
which Notes are considered to be "outstanding" for purposes of this Section
9.02.

            (b) Notwithstanding Section 9.02(a), without the consent of each
Holder affected, an amendment, supplement or waiver, including a waiver pursuant
to Section 6.04, may not (with respect to any Notes held by a non-consenting

      must consent to an amendment, supplement or waiver;

            (2) reduce the principal of or change the Stated Maturity of any
      Note or alter the provisions relating to the Redemption Price of any Note
      at any time;

            (3) reduce the rate of or change the time for payment of interest on
      any Note;

            (4) waive a Default or Event of Default in the payment of principal
      of, or interest or premium, on the Notes (except a rescission of
      acceleration of the Notes by the Holders of at least a majority in
      aggregate principal amount of the Notes and a waiver of the payment
      default that resulted from such acceleration);

            (5) make any Note payable in money other than U.S. Legal Tender;

            (6) release any Guarantor from any of its obligations under its Note
      Guarantee or this Indenture, except in accordance with the terms of this
      Indenture and such Note Guarantee; or

            (7) make any change in Section 6.04 or 6.07 hereof or this Section
      9.02.

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

                                      -83-
<PAGE>

            (d) After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Issuer shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuer to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amendment, supplement or
waiver.

SECTION 9.03. Compliance with TIA.

            From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture or the Notes shall
comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents.

            (a) 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 notice to the Trustee or the Issuer received
before the date on which the Trustee receives an Officers' Certificate
certifying that the Holders of the requisite principal amount of the Notes have
consented (and not theretofore revoked such consent) to the amendment,
supplement or waiver.

            (b) The Issuer 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 at least 30 days prior to the
first solicitation of such consent. If a Record Date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Noteholders at such Record Date (or their duly designated
proxies), and only those Persons, shall be entitled to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
Record Date. No such consent shall be valid or effective for more than 90 days
after such Record Date. The Issuer shall inform the Trustee in writing of the
fixed Record Date if applicable.

            (c) After an amendment, supplement or waiver becomes effective, it
shall bind every Noteholder, unless it makes a change described in any of
clauses (1) through (8) of Section 9.02(b), in which case, the amendment,
supplement or waiver shall bind only each Holder of a Note who has consented to
it and every subsequent Holder of a Note or portion of a Note that evidences the
same debt as the consenting Holder's Note; provided that any such waiver shall
not impair or affect the right of any Holder to receive payment of principal of
and interest and premium, if any, on a Note, on or after the respective due
dates expressed in such Note, or to bring suit for the enforcement of any such
payment on or after such respective dates without the consent of such Holder.

SECTION 9.05. Notation on or Exchange of Notes.

            If an amendment, supplement or waiver changes the terms of a Note,
the Issuer may require the Holder of the Note to deliver it to the Trustee. The
Issuer shall provide the Trus-

                                      -84-
<PAGE>

tee with an appropriate notation on the Note about the changed terms and cause
the Trustee to return it to the Holder at the Issuer's expense. Alternatively,
if the Issuer or the Trustee so determines, the Issuer in exchange for the Note
shall issue and the Trustee shall authenticate a new Note that reflects the
changed terms. Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06. 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 and an Officers' Certificate each stating that the
execution of any amendment, supplement or waiver authorized pursuant to this
Article IX is authorized or permitted by this Indenture and constituted the
legal, valid and binding obligations of the Issuer enforceable in accordance
with its terms. Such Opinion of Counsel shall be at the expense of the Issuer.

                                    ARTICLE X

                                  SUBORDINATION

SECTION 10.01. Agreement to Subordinate.

            The Issuer agrees, and each Holder by accepting a Note agrees, that
the payment of principal, interest and premium, if any, on the Notes shall be
subordinated in right of payment, to the extent and in the manner provided in
this Article X, to the prior payment in full in cash of all Senior Debt of the
Issuer, including Senior Debt incurred after the date of this Indenture, and
that the subordination is for the benefit of the holders of Senior Debt.

SECTION 10.02. Liquidation; Dissolution; Bankruptcy.

            Upon any distribution to creditors of the Issuer: (i) in a
liquidation or dissolution of the Issuer; (ii) in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Issuer or its
property; (iii) in an assignment for the benefit of creditors; or (iv) in any
marshaling of the Issuer's assets and liabilities, (1) the holders of Senior
Debt of the Issuer shall be entitled to receive payment in full in cash of all
Obligations due in respect of Senior Debt of the Issuer before the Holders of
Notes will be entitled to receive any payment or distribution with respect to
the Notes (except that Holders of Notes may receive and retain Permitted Junior
Securities and payments made from the trust pursuant to Article VIII hereof),
and (2) until all Obligations with respect to Senior Debt of the Issuer are paid
in full in cash, any payment or distribution to which the Holder would be
entitled (except for Permitted Junior Securities and payments from the trust
pursuant to Article VIII hereof) shall be made to the holders of such Senior
Debt as their interests may appear.

                                      -85-

SECTION 10.03. Default on Designated Senior Debt.

            (a) The Issuer may not make any payment in respect of the Notes
(except in Permitted Junior Securities and payments made from the trust pursuant
to Article VIII hereof) if:

            (1) a payment default on Designated Senior Debt of the Issuer occurs
      and is continuing beyond any applicable grace period; or

            (2) any other default occurs and is continuing on any series of
      Designated Senior Debt of the Issuer that permits holders of that series
      of Designated Senior Debt of the Issuer to accelerate its maturity and the
      Trustee receives a notice of such default (a "PAYMENT BLOCKAGE NOTICE")
      from the Representative of the holders of any such Designated Senior Debt
      of the Issuer.

            (b) Payments on the Notes may and shall be resumed:

            (1) in the case of a payment default on Designated Senior Debt of
      the Issuer, upon the date on which such default is cured or waived; and

            (2) in case of any default referred to in Section 10.03(a)(2) on
      Designated Senior Debt of the Issuer, the earlier of (x) the date on which
      such default is cured or waived, (y) 179 days after the date on which the
      applicable Payment Blockage Notice is received or (z) the date the Trustee
      receives notice from the Representative for such Designated Senior Debt
      rescinding the Payment Blockage Notice, unless in each case the maturity
      of such Designated Senior Debt of the Issuer has been accelerated (and has
      not been rescinded).

            (c) No new Payment Blockage Notice may be delivered unless and
until:

            (1) 360 days have elapsed since the delivery of the immediately
      prior Payment Blockage Notice; and

            (2) all scheduled payments of principal, interest and premium, if
      any, on the Notes that have come due have been paid in full in cash.

            (d) No default referred to in Section 10.03(a)(2) that existed or
was continuing on the date of delivery of any Payment Blockage Notice to the
Trustee shall be, or be made, the basis for a subsequent Payment Blockage Notice
unless such default has been cured or waived for a period of not less than 90
days.

SECTION 10.04. Acceleration of Securities.

            The Issuer and the Trustee must promptly notify holders of the

of Default.

SECTION 10.05. When Distribution Must Be Paid Over.

            In the event that the Trustee or any Holder receives any payment of
any Obligations with respect to the Notes (except in Permitted Junior Securities
or from the trust pursuant to Article VIII hereof) at a time when:

            (1) the payment is prohibited by this Article X; and

            (2) the Trustee or such Holder, as applicable, has actual knowledge
      that such payment is prohibited by Article X hereof, provided that such
      actual knowledge shall not be required in the case of any payment default
      on Designated Senior Debt of the Issuer,

the Trustee or such Holder, as the case may be, shall hold the payment in trust
for the benefit of the holders of Senior Debt of the Issuer. Upon the proper
written request of the holders of Senior Debt of the Issuer or if there is any
payment default on any Designated Senior Debt, the Trustee or the Holder, as the
case may be, shall deliver the amounts in trust to the holders of Senior Debt of
the Issuer or their proper Representative, for application to the payment of all
Obligations with respect to Senior Debt remaining unpaid to the extent necessary
to pay such Obligations in full in accordance with their terms, after giving
effect to any concurrent payment or distribution to or for the holders of Senior
Debt.

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

SECTION 10.06. Notice by the Issuer.

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

SECTION 10.07. Subrogation.

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

                                      -87-
<PAGE>

SECTION 10.08. Relative Rights.

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

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

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

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

            If the Issuer fails because of this Article X to pay principal of,
premium, if any, or interest on a Note on the due date, the failure is still a
Default or Event of Default.

SECTION 10.09. Subordination May Not Be Impaired by the Issuer.

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

            Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt of the Issuer may, at any time and from
time to time, without the consent of or notice to the Trustee or the
Noteholders, without incurring responsibility to the Trustee or the Noteholders
and without impairing or releasing the subordination provided in this Article X
or the obligations hereunder of the Trustee and the Noteholders to the holders
of such Senior Debt, do any one or more of the following: (1) change the manner,
place, terms or time of payment or extend the time of payment of, or renew or
alter, such Senior Debt or any instrument evidencing the same or any agreement
under which such Senior Debt is outstanding; (2) sell, exchange, impair, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
such Senior Debt; (3) release any Person liable in any manner for the collection
or payment of such Senior Debt; and (4) exercise or refrain from exercising any
rights against the Issuer or any other Person.

SECTION 10.10. Distribution or Notice to Representative.

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

            Upon any payment or distribution of assets of the Issuer referred to
in this Article X, the Trustee and the Holders of Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction or
upon any certificate of such Representative or of the liquidating trustee or
agent or other Person making any distribution to the Trustee or to the Hold-

                                      -88-
<PAGE>

ers of Notes for the purpose of ascertaining the Persons entitled to participate
in such distribution, the holders of the Senior Debt and other Indebtedness of
the Issuer, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article X.

SECTION 10.11. Rights of Trustee and Paying Agent.

            Notwithstanding the provisions of this Article X or any other
provision of this Indenture, the Trustee shall not be charged with knowledge of
the existence of any facts that would prohibit the making of any payment or
distribution by the Trustee, and the Trustee and the Paying Agent may continue
to make payments on the Notes, unless the Trustee shall have received at its
Corporate Trust Office at least five Business Days prior to the date of such
payment written notice of facts that would cause the payment of any Obligations
with respect to the Notes to violate this Article X. Only the Issuer or a
Representative of a series of Designated Senior Debt may give the notice.
Nothing in this Article X shall impair the claims of, or payments to, the
Trustee (in its capacity as such) under or pursuant to Section 7.07 hereof.

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

SECTION 10.12. Authorization To Effect Subordination.

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

                                   ARTICLE XI

                                GUARANTY OF NOTES

SECTION 11.01. Guaranty.

            (a) Subject to the provisions of this Article XI, each of the
Guarantors hereby, jointly and severally, unconditionally Guarantees to each
Holder of a Note authenticated and delivered by the Trustee and to the Trustee
and its successors and assigns that: (i) the principal of, premium, if any, and
interest on with respect to the Notes will be duly and punctually paid in full
when due, whether at maturity, by acceleration or otherwise, and interest on the
overdue principal and (to the extent permitted by law) interest, on the Notes
and all other obligations of the Issuer or the Guarantors to the Holders or the
Trustee hereunder or thereunder (including fees and expenses) will be promptly
paid in full or performed, all in accordance with the terms hereof and thereof;
and (ii) in case of any extension of time of payment or renewal of any Notes or
any such obligations with respect to the Notes, the same will be promptly paid
in full when due or per-

                                      -89-
<PAGE>

formed in accordance with the terms of the extension or renewal, whether at the
extended Stated Maturity, by acceleration or otherwise. This Note Guarantee is a
present and continuing guaranty of payment and performance, and not of
collectibility. Accordingly, failing payment when due of any amount so
Guaranteed, or failing performance of any other obligation of the Issuer to the
Holders under this Indenture or the Notes, for whatever reason, each Guarantor
shall be obligated to pay, or to perform or cause the performance of, the same
immediately.

            (b) Each Guarantor hereby agrees that its obligations under its Note
Guarantee shall be absolute and unconditional, irrespective of any invalidity,
irregularity or unenforceability of the Notes or this Indenture, the absence of
any action to enforce the same, any waiver or consent by any Holder of the Notes
with respect to any provisions hereof or thereof, any release of any other
Guarantor or any other obligor under the Notes, the recovery of any judgment
against the Issuer, any action to enforce the same, whether or not a Note
Guarantee is affixed to any particular Note, or, to the fullest extent permitted
by law, any other circumstance which might otherwise constitute a legal or
equitable discharge or defense of a guarantor. Each Guarantor hereby waives, to
the fullest extent permitted by law, the benefit of diligence, presentment,
demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of the Issuer or any other obligor under the Notes, any right to
require a proceeding first against the Issuer or any such obligor, protest,
notice and all demands whatsoever and covenants that its Note Guarantee will not
be discharged except by complete performance the obligations contained in the
Notes, this Indenture and its Note Guarantee. If any Holder or the Trustee is
required by any court or otherwise to return to the Issuer or to any other
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Issuer or such Guarantor, any amount paid by the
Issuer or such Guarantor to the Trustee or such Holder, each Note Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect.
Each Guarantor further agrees that, as between it, on the one hand, and the
Holders of Notes and the Trustee, on the other hand, (i) subject to this Article
XI, the maturity of the obligations Guaranteed hereby may be accelerated as
provided in Article VI hereof for the purposes of each Note Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the obligations Guaranteed by this Note Guarantee,
and (ii) in the event of any acceleration of such obligations as provided in
Article VI hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by each Guarantor for the purpose of its Note
Guarantee. Upon the effectiveness of any acceleration of the obligations
Guaranteed by this Note Guarantee, the Trustee shall promptly make a demand for
payment of such obligations by each Guarantor under this Note Guarantee. The
obligations of the Guarantors under this Note Guarantee shall be joint and
several.

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

                                      -90-
<PAGE>

rescinded, reduced, restored or returned, the Notes shall, to the fullest extent
permitted by law, be reinstated and deemed reduced only by such amount paid and
not so rescinded, reduced, restored or returned.

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

            (e) Each Note Guarantee may be modified from time to time, without
the consent of the Holders, to reflect such fraudulent conveyance savings
provisions, net worth or maximum amount limitations as to recourse or similar
provisions as are set forth in, and after giving effect to, any guaranty by any
Guarantor of any Senior Debt with respect to the Credit Facilities as such
guaranty may be amended or otherwise modified from time to time, provided that
no such modification of this Note Guarantee shall adversely affect the Holders
in any respect or shall disadvantage the Holders relative to the holders of
Indebtedness of such Guarantor with respect to the Credit Facilities.

SECTION 11.02. Execution Delivery of Note Guarantee.

            To evidence its Note Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Note Guarantee substantially in
the form included in Exhibit E shall be endorsed by an Officer of such Guarantor
on each Note authenticated and delivered by the Trustee and that this Indenture
shall be executed on behalf of such Guarantor by an Officer of such Guarantor.

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

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

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

            In the event that the Issuer creates or acquires any new
Subsidiaries subsequent to the date of this Indenture, if required by Section
4.20, the Issuer shall cause such Subsidiaries to execute supplemental
indentures to this Indenture and Note Guarantees in accordance with Section 4.20
and this Article XI, to the extent applicable.

SECTION 11.03. Additional Guarantors.

            Any Person may become a guarantor of the Notes by executing and
delivering to the Trustee (i) a supplemental indenture in form and substance
satisfactory to the Trustee, which subjects such Person to the provisions of
this Indenture as a guarantor of the Notes, and (ii) an

                                      -91-
<PAGE>

Opinion of Counsel to the effect that such supplemental indenture has been duly
authorized and executed by such Person and constitutes the legal, valid, binding
and enforceable obligation of such person (subject to such customary exceptions
concerning fraudulent conveyance laws, creditors' rights and equitable
principles as may be acceptable to the Trustee in its discretion).

SECTION 11.04. Release of Guarantor.

            Any Guarantor will be released and relieved of any obligations under
its Note Guarantee:

            (a) in connection with any sale or other disposition of all or
substantially all of the assets of that Guarantor (including by way of merger or
consolidation) to a Person that is not (either before or after giving effect to
such transaction) a Restricted Subsidiary of the Issuer, if the sale or other
disposition of all or substantially all of the assets of that Guarantor complies
with Section 4.13, including the application of the Net Proceeds therefrom;

            (b) in connection with any sale of all of the Capital Stock of a
Guarantor to a Person that is not (either before or after giving effect to such
transaction) a Restricted Subsidiary of the Issuer, if the sale of all such
Capital Stock of that Guarantor complies with Section 4.13, including the
application of the Net Proceeds therefrom;

            (c) if the Issuer properly designates any Restricted Subsidiary that
is a Guarantor as an Unrestricted Subsidiary;

            (d) in connection with any sale of Capital Stock of a Guarantor to a
Person that results in the Guarantor no longer being a Subsidiary of the Issuer,
if the sale of such Capital Stock of that Guarantor complies with Section 4.13,
including the application of the Net Proceeds therefrom;

            (e) if the Issuer exercises its Legal Defeasance option or its
Covenant Defeasance option as described in Section 8.02 or if its obligations
under this Indenture are discharged in accordance with the terms of this
Indenture; or

            (f) if the Guarantee by such Guarantor, if any, of, and all pledges
and security interests, if any, granted by such Guarantor in connection with all
Indebtedness of the Issuer or any Restricted Subsidiary the Guarantee of which
by such Guarantor (or the pledge of assets by such Guarantor in connection
therewith) would have required such Guarantor to Guarantee the Notes pursuant to
Section 4.16 (including, without limitation, the Credit Agreement), have been
released.

SECTION 11.05. Guarantors May Consolidate, etc., on Certain Terms.

            (a) Except as otherwise provided in Section 11.04, a Guarantor shall
not, directly or indirectly, consolidate or merge with or into another Person
(whether or not the Guarantor is the surviving corporation), and the Guarantor
will not sell, assign, transfer, convey or otherwise dispose of all or
substantially all of the properties or assets of the Guarantor in one or

                                      -92-
<PAGE>

more related transactions, to another Person (including by way of consolidation
or merger), unless:

            (1) immediately after giving effect to such transaction, no Default
      or Event of Default exists; and

            (2) either: (i) the Person acquiring the property in such sale or
      disposition or the Person formed by or surviving any such consolidation or
      merger is a corporation, partnership or limited liability company,
      organized under (A) the laws of the United States, any state thereof or
      the District of Columbia or (B) the laws of the same jurisdiction as that
      Guarantor and, in each case, assumes all the obligations of that Guarantor
      under this Indenture, its Note Guarantee and the Registration Rights
      Agreement pursuant to a supplemental indenture in the form set forth in
      Exhibit H and satisfactory to the Trustee, or (ii) such sale or other
      disposition complies with Section 4.13, including the application of the
      Net Proceeds therefrom.

            (b) No Guarantor may, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person.

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

            (d) In connection with any such consolidation, merger, sale,
assignment, transfer, conveyance or other disposition, such Guarantor shall
deliver, or cause to be delivered, to the Trustee, in form and substance
satisfactory to the Trustee, an Officers' Certificate and an Opinion of Counsel,
each stating that such consolidation, merger, sale, assignment, transfer,
conveyance or other disposition and the supplemental indenture in respect
thereto comply with this Indenture and that all conditions precedent therein
provided for relating to such transactions have been complied with.

            (e) Except as set forth in Articles IV and V hereof, nothing
contained in this Indenture or in any of the Notes shall prevent any
consolidation or merger of a Guarantor with or into the Issuer or another
Guarantor, or shall prevent any sale or conveyance of the property of a
Guarantor as an entirety or substantially as an entirety to the Issuer or
another Guarantor.

SECTION 11.06. Subordination of Note Guarantee.

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

York will be the office of the Trustee maintained for such purpose.

            SECTION 3. Paying Agent and Registrar. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Issuer may change any Paying Agent or Registrar without notice to
any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

            SECTION 4. Indenture. The Issuer issued the Notes under an Indenture
dated as of August 27, 2004 (the "INDENTURE") between the Issuer and the
Trustee. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"). The

                                      A-4
<PAGE>

Notes are subject to all such terms, and Holders are referred to the Indenture
and the TIA for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.

            SECTION 5. Optional Redemption. At any time prior to September 1,
2007, the Issuer may on any one or more occasions redeem up to 35% of the
aggregate principal amount of Notes issued under the Indenture (which includes
any Additional Notes) at a Redemption Price of 108.500% of the principal amount
thereof, plus accrued and unpaid interest thereon, to the Redemption Date, with
the net cash proceeds of one or more Designated Offerings of the Issuer (or of
any Parent to the extent such proceeds are contributed to the equity capital of
the Issuer, other than in the form of Disqualified Stock); provided that (1) at
least 65% of the aggregate principal amount of Notes issued under the Indenture
(which includes any Additional Notes) remains outstanding immediately after the
occurrence of such redemption (excluding Notes held by the Issuer and its
Subsidiaries) and (2) such redemption occurs within 90 days of the date of the
closing of such Designated Offering.

            On or after September 1, 2009, the Issuer may redeem all or part of
the Notes, at the Redemption Prices (expressed as percentages of principal
amount) set forth below plus accrued and unpaid interest thereon, to the
applicable Redemption Date, if redeemed during the twelve-month period beginning

</TABLE>

            SECTION 6. Offers to Purchase. The Indenture provides that upon the
occurrence of a Change of Control or an Asset Sale and subject to further
limitations contained therein, the Issuer shall make an offer to purchase
outstanding Notes in accordance with the procedures set forth in the Indenture.

            SECTION 7. Notice of Redemption. Notice of redemption will be mailed
by first class mail at least 30 days but not more than 60 days before the
Redemption Date to each Holder of the Notes to be redeemed at its registered
address. No Notes of $1,000 or less shall be redeemed in part. If any Note is to
be redeemed in part only, the notice of redemption that relates to such Note
shall state the portion of the principal amount thereof to be redeemed. A new
Note in principal amount equal to the unredeemed portion of the original Note
will be issued in the name of the Holder thereof upon cancellation of the
original Note. On and after the Redemption Date, interest ceases to accrue on
Notes or portions of them called for redemption.

            SECTION 8. Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 principal amount and
integral multiples of $1,000 principal amount. The transfer of the Notes may be
registered and the Notes may be exchanged as provided in the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Issuer may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.

                                      A-5
<PAGE>

The Issuer or the Registrar is not required to transfer or exchange any Note
selected for redemption. Also, the Issuer or the Registrar is not required to
transfer or exchange any Notes for a period of 15 days before a selection of the
Notes to be redeemed.

            SECTION 9. Persons Deemed Owners. The registered Holder of a Note
may be treated as its owner for all purposes.

            SECTION 10. Amendment, Supplement and Waiver. Subject to certain
exceptions, the Indenture and the Notes may be amended or supplemented with the
written consent of the Holders of at least a majority in aggregate principal
amount of the Notes then outstanding, and any existing Default or compliance
with any provision may be waived with the consent of the Holders of a majority
in aggregate principal amount of the Notes then outstanding. Without notice to
or consent of any Holder, the parties thereto may amend or supplement the
Indenture and the Notes to, among other things, cure any ambiguity, defect or
inconsistency in the Indenture, provide for uncertificated Notes in addition to
certificated Notes, comply with any requirements of the Commission in connection
with the qualification of the Indenture under the TIA, or make any change that
does not adversely affect the rights of any Holder of a Note.

            SECTION 11. Defaults and Remedies. If a Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes generally may declare the principal of and
accrued interest, if any, on such Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of a Default arising from certain
events of bankruptcy or insolvency as set forth in the Indenture all outstanding
Notes will become due and payable without further action or notice. Holders of
the Notes may not enforce the Indenture or the Notes except as provided in the
Indenture. Subject to certain limitations, Holders of a majority in aggregate
principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders notice of
any continuing Default (except a Default relating to the payment of principal or
interest) if it determines that withholding notice is in their interest. The
Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any Default and its consequences under the Indenture except a
continuing Default in the payment of interest on, or the principal of the Notes
or in respect of certain covenants set forth in the Indenture.

            SECTION 12. Restrictive Covenants. The Indenture contains certain
covenants that, among other things, limit the ability of the Issuer and its
Restricted Subsidiaries to make restricted payments, to incur indebtedness, to
create liens, to sell assets, to permit restrictions on dividends and other
payments by Restricted Subsidiaries of the Issuer, to consolidate, merge or sell
all or substantially all of its assets or to engage in transactions with
affiliates. The limitations are subject to a number of important qualifications
and exceptions. The Issuer must annually report to the Trustee on compliance
with such limitations.

            SECTION 13. No Recourse Against Others. No director, officer,
employee, incorporator, member, partner or stockholder of the Issuer, any
Guarantor, any Subsidiary, or any Parent shall have any liability for any
obligations of the Issuer or the Guarantors under the Notes, the Indenture, the
Note Guarantees or for any claim based on, in respect of, or by reason of, such

                                      A-6
<PAGE>

obligations or their creation. Each Holder of the Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

            SECTION 14. Trustee Dealings with the Issuer. The Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of the Notes and may otherwise deal with the Issuer, its Subsidiaries or
their respective Affiliates as if it were not the Trustee.

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

            SECTION 16. Abbreviations. Customary abbreviations may be used in
the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
ENT (= tenants by the entirety), JT TEN (= joint tenants with right of
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (=
Uniform Gifts to Minors Act).

            SECTION 17. Additional Rights of Holders of Restricted Global Notes
and Restricted Definitive Notes. Pursuant to, but subject to the exceptions in,
the Registration Rights Agreement, the Issuer will be obligated to consummate an
exchange offer pursuant to which the Holder of this Note shall have the right to
exchange this Note for an 8-1/2% Senior Subordinated Note due 2014 of the Issuer
which shall have been registered under the Securities Act, in like principal
amount and having terms identical in all material respects to this Note (except
that such note shall not be entitled to Additional Interest). The Holders shall
be entitled to receive certain Additional Interest in the event such exchange
offer is not consummated or the Notes are not offered for resale and upon
certain other conditions, all pursuant to and in accordance with the terms of
the Registration Rights Agreement.(a)

            SECTION 18. CUSIP Numbers. Pursuant to a recommendation promulgated
by the Committee on Uniform Security Identification Procedures, the Issuer 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.

            SECTION 19. Guarantees. The Note will be entitled to the benefits of
certain Guarantees made for the benefit of the Holders. Reference is hereby made
to the Indenture for a statement of the respective rights, limitations of
rights, duties and obligations thereunder of the Guarantors, the Trustee and the
Holders.

            SECTION 20. Governing Law. THIS NOTE SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO CONFLICTS OF LAW PRINCIPLES THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION.

Ladies and Gentlemen:

            In connection with our proposed purchase of 8-1/2% Senior
Subordinated Notes due 2014 (the "Notes") of THL BUILDCO, INC., a Delaware
corporation (the "Issuer"), we confirm that:

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

            2.    We understand that the offer and sale of the Notes have not
      been registered under the Securities Act, and that the Notes may not be
      offered or sold except as permitted in the following sentence. We agree,
      on our own behalf and on behalf of any accounts for which we are acting as
      hereinafter stated, that if we should sell any Notes, we will do so only
      (i) to the Issuer or any of its subsidiaries, (ii) inside the United
      States in accordance with Rule 144A under the Securities Act to a
      "qualified institutional buyer" (as defined in Rule 144A under the
      Securities Act), (iii) inside the United States to an institutional
      "accredited investor" (as defined below) that, prior to such transfer,
      furnishes (or has furnished on its behalf by a U.S. broker-dealer) to the
      Trustee (as defined in the Indenture) a signed letter containing certain
      representations and agreements relating to the restrictions on transfer of
      the Notes (the form of which letter can be obtained from the Trustee),
      (iv) outside the United States in accordance with Regulation S promulgated
      under the Securities Act to non-U.S. persons, (v) pursuant to the
      exemption from registration provided by Rule 144 under the Securities Act
      (if available), (vi) in accordance with another exemption from the
      registration requirements of the Securities Act (and based upon an opinion
      of counsel if the Issuer so requests) or (vii) pursuant to an effective
      registration statement under the Securities Act, and we further agree to
      provide to any person purchasing any of the Notes from us a notice
      advising such purchaser that resales of the Notes are restricted as stated
      herein.

                                      E-1

            3.    We are not acquiring the Notes for or on behalf of, and will
      not transfer the Notes to, any pension or welfare plan (as defined in
      Section 3 of the Employee Retirement Income Security Act of 1974, as
      amended) or plan (as defined in Section 4975 of the Internal Revenue Code
      of 1986, as amended), except as permitted in the section entitled "Notice
      to Investors" of the Offering Memorandum dated August 12, 2004, relating
      to the Notes.

            4.    We understand that, on any proposed resale of any Notes, we
      will be required to furnish to the Trustee and the Issuer such
      certification, legal opinions and other information as the Trustee and the
      Issuer 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.

            5.    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 their investment, as the case may be.

            6.    We are acquiring the Notes purchased by us for our 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.

      States;

            (2)   either (a) at the time the buy offer was originated, the
      transferee was outside the United States or we and any person acting on
      our behalf reasonably believed that the transferee was outside the United
      States, or (b) the transaction was executed in, on or through the
      facilities of a designated offshore securities market and neither we nor
      any person acting on our behalf knows that the transaction has been
      prearranged with a buyer in the United States;

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

            (4)   the transaction is not part of a plan or scheme to evade the

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