                                   THE NOTES

Section 2.01      Form and Dating.

                  (a)      General. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A1 hereto. The
Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage. Each Note shall be dated the date of its
authentication. The Notes shall be issued in registered, global form without
interest coupons and only shall be in minimum denominations of $1,000 and
integral multiples of $1,000 in excess thereof.

                  The terms and provisions contained in the Notes shall
constitute, and are hereby expressly made, a part of this Indenture and the
Company, the Guarantors and the Trustee, by their execution and delivery of
this Indenture, expressly agree to such terms and provisions and to be bound
thereby. However, to the extent any provision of any Note conflicts with the
express provisions of this Indenture, the provisions of this Indenture shall
govern and be controlling.

                  (b)      Global Notes. Notes issued in global form shall be
substantially in the form of Exhibit A1 or A2 attached hereto (including the
Global Note Legend thereon and the "Schedule of Exchanges of Interests in the
Global Note" attached thereto). Notes issued in

                                      21
<PAGE>

definitive form shall be substantially in the form of Exhibit A1 attached
hereto (but without the Global Note Legend thereon and without the "Schedule of
Exchanges of Interests in the Global Note" attached thereto). Each Global Note
shall represent such of the outstanding Notes as shall be specified therein and
each shall provide that it shall represent the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate
principal amount of outstanding Notes represented thereby may from time to time
be reduced or increased, as appropriate, to reflect exchanges and redemptions.
Any endorsement of a Global Note to reflect the amount of any increase or
decrease in the aggregate principal amount of outstanding Notes represented
thereby shall be made by the Trustee in accordance with instructions given by
the Holder thereof as required by Section 2.07 hereof.

                  (c)      Temporary Global Notes. Notes offered and sold in
reliance on Regulation S shall be issued initially in the form of the

purchasers of the Notes represented thereby with the Trustee, as custodian for
The Depository Trust Company ("DTC") in New York, New York, and registered in
the name of the Depositary or the nominee of the Depositary for the accounts of
designated agents holding on behalf of Euroclear or Clearstream, duly executed
by the Company and authenticated by the Trustee as hereinafter provided. The
Restricted Period shall be terminated upon the receipt by the Trustee of (i) a
written certificate from Euroclear and Clearstream certifying that they have
received certification of non-United States beneficial ownership of 100% of the
aggregate principal amount at maturity of the Regulation S Temporary Global
Note (except to the extent of any Beneficial Owners thereof who acquired an
interest therein during the Restricted Period pursuant to another exemption
from registration under the Securities Act and who shall take delivery of a
beneficial ownership interest in a 144A Global Note bearing a Private Placement
Legend, all as contemplated by Section 2.07(a)(ii) hereof), and (ii) an
Officers' Certificate from the Company. Following the termination of the
Restricted Period, beneficial interests in the Regulation S Temporary Global
Note shall be exchanged for beneficial interests in Regulation S Permanent
Global Notes pursuant to the Applicable Procedures. Simultaneously with the
authentication of Regulation S Permanent Global Notes, the Trustee shall cancel
the Regulation S Temporary Global Note. The aggregate principal amount of the
Regulation S Temporary Global Note and the Regulation S Permanent Global Notes
may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depositary or its nominee, as the case may be,
in connection with transfers of interest as hereinafter provided.

                  (d)      Euroclear and Clearstream Procedures Applicable. The
provisions of the "Operating Procedures of the Euroclear System" and "Terms and
Conditions Governing Use of Euroclear" and the "General Terms and Conditions of

transfers of beneficial interests in the Regulation S Temporary Global Note and
the Regulation S Permanent Global Notes that are held by Participants through
Euroclear or Clearstream.

Section 2.02      Execution and Authentication.

                  Two Officers of the Company shall sign the Notes for the
Company by manual or facsimile signature.

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

                  A Note shall not be valid until authenticated by the manual
signature of the Trustee. Such signature shall be conclusive evidence that the
Note has been authenticated under this Indenture.

                  The Trustee shall, upon a written order of the Company signed
by two Officers of the Company (an "AUTHENTICATION ORDER"), authenticate Notes
for original issue with a maximum aggregate principal amount of $300.0 million,
of which $175.0 million will be issued on the date of this Indenture. The
aggregate principal amount of Notes outstanding at any time may not exceed
$300.0 million except as provided in Section 2.08.

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

Section 2.03      Methods of Receiving Payments on the Notes.

                  If a Holder of Notes has given wire transfer instructions to
the Company, the Company shall pay all principal, interest and premium and
Liquidated Damages, if any, on that Holder's Notes in accordance with those
instructions. All other payments on Notes shall be made at the office or agency
of the Paying Agent and Registrar within the City and State of New York unless
the Company elects to make interest payments by check mailed to the Holders at
their addresses set forth in the register of Holders.

Section 2.04      Registrar and Paying Agent.

                  The Company shall maintain an office or agency where Notes
may be presented for registration of transfer or for exchange ("REGISTRAR") and
an office or agency where Notes may be presented for payment ("PAYING AGENT").
The Registrar shall keep a register of the Notes and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional paying agents. The term "Registrar" includes any co-registrar and
the term "Paying Agent" includes any additional paying agent. The Company may
change any Paying Agent or Registrar without prior notice to any Holder. The
Company shall notify the Trustee in writing of the name and address of any
Agent not a party to this Indenture. If the Company fails to appoint or
maintain another entity as Registrar or Paying Agent, the Trustee shall act as
such. The Company or any of its Subsidiaries may act as Paying Agent or
Registrar.

                  The Company initially appoints DTC to act as Depositary with
respect to the Global Notes. Accordingly, at all times that the Trustee is
acting as Registrar, Paying Agent, or

                                      23
<PAGE>

Custodian, all rights provided the Trustee under this Agreement shall apply
whether it is acting in its capacity as Trustee, Registrar, Paying Agent or
Custodian.

                  The Company initially appoints the Trustee to act as the
Registrar and Paying Agent and to act as Custodian with respect to the Global
Notes.

Section 2.05      Paying Agent to Hold Money in Trust.

                  The Company shall require each Paying Agent other than the
Trustee to agree in writing that the Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by the Paying Agent for the
payment of principal, premium or Liquidated Damages, if any, or interest on the
Notes, and shall notify the Trustee of any default by the Company in making any
such payment. While any such default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee and to account for any
funds disbursed by it prior to such time. The Company at any time may require a
Paying Agent to pay all money held by it to the Trustee. Upon payment over to
the Trustee, the Paying Agent (if other than the Company or one of its
Subsidiaries) shall have no further liability for the money delivered to the
Trustee. If the Company or one of its Subsidiaries acts as Paying Agent, it
shall segregate and hold in a separate trust fund for the benefit of the
Holders all money held by it as Paying Agent. Upon any bankruptcy or
reorganization proceedings relating to the Company, the Trustee shall serve as
Paying Agent for the Notes.

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 all Holders and shall otherwise comply with TIA ss. 312(a). If the
Trustee is not the Registrar, the Company shall furnish to the Trustee at least
fifteen Business Days before 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 the Holders
of Notes and the Company shall otherwise comply with TIA ss. 312(a).

Section 2.07      Transfer and Exchange.

                  (a)      Transfer and Exchange of Global Notes. A Global Note
may not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Notes shall be exchanged by the Company for Definitive Notes if (i) the Company
delivers to the Trustee notice from the Depositary that it is unwilling or
unable to continue to act as Depositary or that it is no longer a clearing
agency registered under the Exchange Act and, in either case, a successor
Depositary is not appointed by the Company within 120 days after the date of
such notice from the Depositary; (ii) the Company in its sole discretion
determines that the Global Notes (in whole but not in part) should be exchanged
for Definitive Notes and delivers a written notice to such effect to the
Trustee; provided that in no event shall the Regulation S Temporary Global Note
be exchanged by the Company for Definitive Notes prior to (x) the expiration of
the Restricted Period and (y) the receipt by the Registrar of any

                                      24
<PAGE>

certificates required pursuant to Rule 903 under the Securities Act; or (iii)
there shall have occurred and be continuing a Default or Event of Default with
respect to the Notes. Upon the occurrence of either of the preceding events in
(i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the
Depositary shall instruct the Trustee. Global Notes also may be exchanged or
replaced, in whole or in part, as provided in Sections 2.08 and 2.11 hereof.
Every Note authenticated and delivered in exchange for, or in lieu of, a Global
Note or any portion thereof, pursuant to this Section 2.07 or Section 2.08 or
2.11 hereof, shall be authenticated and delivered in the form of, and shall be,
a Global Note. A Global Note may not be exchanged for another Note other than
as provided in this Section 2.07(a), however, beneficial interests in a Global
Note may be transferred and exchanged as provided in Section 2.07(b), (c) or
(f) hereof.

                  (b)      Transfer and Exchange of Beneficial Interests in the
Global Notes. The transfer and exchange of beneficial interests in the Global
Notes shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial
interests in the Restricted Global Notes shall be subject to restrictions on
transfer comparable to those set forth herein to the extent required by the
Securities Act. Transfers of beneficial interests in the Global Notes also
shall require compliance with either subparagraph (i) or (ii) below, as
applicable, as well as one or more of the other following subparagraphs, as
applicable:

                  (i)      Transfer of Beneficial Interests in the Same Global
         Note. Beneficial interests in any Restricted Global Note may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in the same Restricted Global Note in accordance
         with the transfer restrictions set forth in the Private Placement
         Legend; provided, however, that prior to the expiration of the
         Restricted Period, transfers of beneficial interests in the Regulation
         S Temporary Global Note may not be made to a U.S. Person or for the
         account or benefit of a U.S. Person (other than an Initial Purchaser).
         Beneficial interests in any Unrestricted Global Note may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in an Unrestricted Global Note. No written orders
         or instructions shall be required to be delivered to the Registrar to
         effect the transfers described in this Section 2.07(b)(i); provided
         that the transferor of such beneficial interest shall deliver notice
         of such transfer to the Registrar.

                  (ii)     All Other Transfers and Exchanges of Beneficial
         Interests in Global Notes. In connection with all transfers and
         exchanges of beneficial interests that are not subject to Section
         2.07(b)(i) above, the transferor of such beneficial interest must
         deliver to the Registrar either (A) (1) a written order from a
         Participant or an Indirect Participant given to the Depositary in
         accordance with the Applicable Procedures directing the Depositary to
         credit or cause to be credited a beneficial interest in another Global
         Note in an amount equal to the beneficial interest to be transferred
         or exchanged and (2) instructions given in accordance with the
         Applicable Procedures containing information regarding the Participant
         account to be credited with such increase or (B) (1) a written order

time. Upon receipt of a request for such an exchange or transfer, the Trustee
shall cancel the applicable Unrestricted Definitive Note and increase or cause
to be increased the aggregate principal amount of one of the Unrestricted
Global Notes, all as set forth in the request.

                  If any such exchange or transfer from a Definitive Note to a
         beneficial interest is effected pursuant to subparagraphs (ii)(B),
         (ii)(D) or (iii) above at a time when an Unrestricted Global Note has
         not yet been issued, the Company shall issue and, upon receipt of an
         Authentication Order in accordance with Section 2.02 hereof, the
         Trustee shall authenticate one or more Unrestricted Global Notes in an
         aggregate principal amount equal to the principal amount of Definitive
         Notes so transferred.

                  (e)      Transfer and Exchange of Definitive Notes for
Definitive Notes. Upon request by a Holder of Definitive Notes and such
Holder's compliance with the provisions of this Section 2.07(e), the Registrar
shall register the transfer or exchange of Definitive Notes. Prior to such
registration of transfer or exchange, the requesting Holder shall present or
surrender to the Registrar the Definitive Notes duly endorsed or accompanied by
a written instruction of transfer in form satisfactory to the Registrar duly
executed by such Holder or by its attorney, duly authorized in writing. In
addition, the requesting Holder shall provide any additional certifications,
documents and information, as applicable, required pursuant to the following
provisions of this Section 2.07(e).

                  (i)      Restricted Definitive Notes to Restricted Definitive

the name of Persons who take delivery thereof in the form of a Restricted
Definitive Note if the Registrar receives the following:

                  (A)      if the transfer shall be made pursuant to Rule 144A

         certificate in the form of Exhibit B hereto, including the
         certifications in item (1) thereof;

                  (B)      if the transfer shall be made pursuant to Rule 903

         form of Exhibit B hereto, including the certifications in item (2)
         thereof; and

                  (C)      if the transfer shall be made pursuant to any other
         exemption from the registration requirements of the Securities Act,
         then the transferor must deliver a

                                      32

         (3) thereof, if applicable.

                  (ii)     Restricted Definitive Notes to Unrestricted
Definitive Notes. Any Restricted Definitive Note may be exchanged by the Holder
thereof for an Unrestricted Definitive Note or transferred to a Person or
Persons who take delivery thereof in the form of an Unrestricted Definitive
Note if:

                  (A)      such exchange or transfer is effected pursuant to
         the Exchange Offer in accordance with the Registration Rights
         Agreement and the Holder, in the case of an exchange, or the
         transferee, in the case of a transfer, certifies in the applicable
         Letter of Transmittal that it is not (1) a broker-dealer, (2) a Person
         participating in the distribution of the Exchange Notes or (3) a
         Person who is an affiliate (as defined in Rule 144) of the Company;

                  (B)      any such transfer is effected pursuant to the Shelf
         Registration Statement in accordance with the Registration Rights
         Agreement;

                  (C)      any such transfer is effected by a Broker-Dealer
         pursuant to the Exchange Offer Registration Statement in accordance
         with the Registration Rights Agreement; or

                  (D)      the Registrar receives the following:

                           (1)      if the Holder of such Restricted Definitive
                  Notes proposes to exchange such Notes for an Unrestricted
                  Definitive Note, a certificate from such Holder in the form
                  of Exhibit C hereto, including the certifications in item
                  (1)(d) thereof; or

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

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

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

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

                                      33

Transmittal that (x) they are not Broker-Dealers, (y) they are not
participating in a distribution of the Exchange Notes and (z) they are not
affiliates (as defined in Rule 144) of the Company, and accepted for exchange
in the Exchange Offer and (ii) Definitive Notes in an aggregate principal
amount equal to the principal amount of the Restricted Definitive Notes
accepted for exchange in the Exchange Offer. Concurrently with the issuance of
such Notes, the Trustee shall cause the aggregate principal amount of the
applicable Restricted Global Notes to be reduced accordingly, and the Company
shall execute and the Trustee shall authenticate and deliver to the Persons
designated by the Holders of Definitive Notes so accepted Definitive Notes in
the appropriate principal amount. Any Notes that remain outstanding after the
consummation of the Exchange Offer, and Exchange Notes issued in connection
with the Exchange Offer, shall be treated as a single class of securities under
this Indenture.

                  (g)      Legends. The following legends shall appear on the
face of all Global Notes and Definitive Notes issued under this Indenture

Indenture.

                  CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS NOTE IS
                  COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE.
                  THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF A HOLDER
                  AFTER THE RESALE RESTRICTION TERMINATION DATE.

         Notwithstanding the foregoing, any Global Note or Definitive Note
         issued pursuant to subparagraph (b)(iv), (c)(iii), (c)(iv), (d)(ii),
         (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.07 (and all Notes
         issued in exchange therefor or substitution thereof) shall not bear
         the Private Placement Legend.

                  (ii)     Global Note Legend. Each Global Note shall bear a
legend in substantially the following form:

<PAGE>

                  THE RIGHTS ATTACHING TO THIS REGULATION S TEMPORARY GLOBAL
                  NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING ITS
                  EXCHANGE FOR CERTIFICATED NOTES, ARE AS SPECIFIED IN THE
                  INDENTURE (AS DEFINED HEREIN). NEITHER THE HOLDER NOR THE
                  BENEFICIAL OWNERS OF THIS REGULATION S TEMPORARY GLOBAL NOTE
                  SHALL BE ENTITLED TO RECEIVE PAYMENT OF INTEREST HEREON.

                  (i)      Cancellation and/or Adjustment of Global Notes. At
such time as all beneficial interests in a particular Global Note have been
exchanged for Definitive Notes or a particular Global Note has been redeemed,
repurchased or canceled in whole and not in part, each such Global Note shall
be returned to or retained and canceled by the Trustee in accordance with
Section 2.12 hereof. At any time prior to such cancellation, if any beneficial
interest in a Global Note is exchanged for or transferred to a Person who shall
take delivery thereof in the form of a beneficial interest in another Global
Note or for Definitive Notes, the principal amount of Notes represented by such
Global Note shall be reduced accordingly and an endorsement shall be made on
such Global Note by the Trustee or by the Depositary at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being
exchanged for or transferred to a Person who shall take delivery thereof in the
form of a beneficial interest in another Global Note, such other Global Note
shall be increased accordingly and an endorsement shall be made on such Global
Note by the Trustee or by the Depositary at the direction of the Trustee to
reflect such increase.

                  (j)      General Provisions Relating to Transfers and
Exchanges.

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

                  (ii)     No service charge shall be made to a Holder of a
beneficial interest in a Global Note or to a Holder of a Definitive Note for
any registration of transfer or exchange, but the Company may require payment
of a sum sufficient to cover any transfer tax or similar governmental charge
payable in connection therewith (other than any such transfer taxes or similar
governmental charge payable upon exchange or transfer pursuant to Sections
2.11, 3.06, 3.09, 4.10, 4.15 and 9.05 hereof).

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

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

                                      36
<PAGE>

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

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

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

                  (viii)   All certifications, certificates and Opinions of
Counsel required to be submitted to the Registrar pursuant to this Section 2.07
to effect a registration of transfer or exchange may be submitted by facsimile
with the original to follow by first class mail.

Section 2.08      Replacement Notes.

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

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

Section 2.09      Outstanding Notes.

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

                  If a Note is replaced pursuant to Section 2.08 hereof, it
ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Note is held by a bona fide

                                      37
<PAGE>

purchaser; provided, however, that the aggregate principal amount of the Notes
shall be deemed not to be increased by reason of this Section 2.09 or Section
2.08 hereof.

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

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

Section 2.10      Treasury Notes.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company or an Affiliate thereof shall be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes that the Trustee knows are so owned shall be so disregarded.

Section 2.11      Temporary Notes.

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

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

Section 2.12      Cancellation.

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

Section 2.13      Defaulted Interest.

                  If the Company defaults in a payment of interest on the
Notes, it shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the Persons who
are Holders on a subsequent special record date, in each

                                      38
<PAGE>

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

Section 2.14      CUSIP Numbers.

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

                                 ARTICLE THREE
                           REDEMPTION AND PREPAYMENT;
                           SATISFACTION AND DISCHARGE

Section 3.01      Notices to Trustee.

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

Section 3.02      Selection of Notes to Be Redeemed.

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

                  The Trustee shall promptly notify the Company in writing of

partial redemption, the principal amount at maturity thereof to be redeemed. No
Notes in amounts of $1,000 or less shall be redeemed in

part. Notes and portions of Notes selected shall be in amounts of $1,000 or
whole multiples of $1,000; except that if all of the Notes of a Holder are to
be redeemed, the entire outstanding amount of Notes held by such Holder, even
if not a multiple of $1,000, shall be redeemed. Except as provided in the
preceding sentence, provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption.

days but not more than 60 days before a redemption date, the Company shall mail
or cause to be mailed, by first class mail, a notice of redemption to each
Holder whose Notes are to be redeemed at its registered address.

                  (a)      the redemption date;

                  (b)      the redemption price;

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

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

                  (e)      that Notes called for redemption must be surrendered
         to the Paying Agent to collect the redemption price and become due on
         the date fixed for redemption;

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

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

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

                  At the Company's request, the Trustee shall give the notice
of redemption in the Company's name and at its expense; provided, however, that
the Company shall have delivered to the Trustee, at least 45 days prior to the
redemption date, an Officers Certificate requesting that the Trustee give such
notice and setting forth the information to be stated in such notice as
provided in the preceding paragraph. The notice, if mailed in the manner
provided herein shall be presumed to have been given, whether or not the Holder
receives such notice.

Section 3.04      Effect of Notice of Redemption.

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

Section 3.05      Deposit of Redemption Price.

                  Not less than one Business Day prior to the redemption date,
the Company shall deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption price of and accrued interest and Liquidated
Damages, if any, on all Notes to be redeemed on that date. The Trustee or the
Paying Agent shall promptly return to the Company any money deposited with the
Trustee or the Paying Agent by the Company in excess of the amounts necessary
to pay the redemption price of, and accrued interest and Liquidated Damages, if
any, on, all Notes to be redeemed.

                  If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest and Liquidated Damages,
if any, shall cease to accrue on the Notes or the portions of Notes called for
redemption. If a Note is redeemed on or after an interest record date but on or
prior to the related interest payment date, then any accrued and unpaid
interest shall be paid to the Person in whose name such Note was registered at
the close of business on such record date. If any Note called for redemption
shall not be so paid upon surrender for redemption because of the failure of
the Company to comply with the preceding paragraph, interest shall be paid on
the unpaid principal, from the redemption date until such principal is paid,
and to the extent lawful on any interest not paid on such unpaid principal, in
each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06      Notes Redeemed in Part.

                  Upon surrender of a Note that is redeemed in part, the
Company shall issue and the Trustee shall authenticate for the Holder at the
expense of the Company a new Note equal in principal amount to the unredeemed
portion of the Note surrendered. No Notes in denominations of $1,000 or less
shall be redeemed in part.

                  (a)      Except as set forth in clause (b) and (c) of this
Section 3.07, the Company shall not have the option to redeem the Notes

interest and Liquidated Damages, if any, thereon, to the applicable redemption
date, if redeemed during the twelve-month period beginning on April 1 of the

the Company shall repurchase Notes pursuant to the Repurchase Offer. The

Purchase Date, except to the extent that a longer period is required by
applicable law (the "OFFER PERIOD"). On the Purchase Date, the Company shall
purchase the principal amount of Notes required to be purchased pursuant to
Sections 4.10 and 4.15 hereof (the "OFFER AMOUNT") or, if less than the Offer
Amount has been tendered, all Notes tendered in response to the Repurchase
Offer. Payment for any Notes so purchased shall be made in the same manner as
interest payments are made.

                  If the Purchase Date is on or after an interest record date
and on or before the related interest payment date, any accrued and unpaid
interest shall be paid to the Person in whose name a Note is registered at the
close of business on such record date, and no additional interest shall be

         shall continue to accrete or accrue interest and Liquidated Damages,
         if any;

                  (d)      that, unless the Company defaults in making such
         payment, any Note (or portion thereof) accepted for payment pursuant
         to the Repurchase Offer shall cease to accrete or accrue interest and
         Liquidated Damages, if any, after the Purchase Date;

                  (e)      that Holders electing to have a Note purchased

         forth the name of the Holder, the principal amount of the Note the
         Holder delivered for purchase and a statement that such Holder is
         withdrawing his election to have such Note purchased;

                  (h)      that, if the aggregate amount of Notes surrendered
         by Holders exceeds the Offer Amount, the Trustee shall select the
         Notes to be purchased pursuant to the terms of Section 3.02 hereof
         (with such adjustments as may be deemed appropriate by the Trustee so
         that only Notes in denominations of $1,000, or integral multiples
         thereof, shall be purchased); and

                  (i)      that Holders whose Notes were purchased only in part

                  (4)      make any Restricted Investment (all such payments
         and other actions set forth in clauses (1) through (4) 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 Company 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
         additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
         test set forth in the first paragraph of Section 4.09; and

                  (3)      such Restricted Payment, together with the aggregate
         amount of all other Restricted Payments made by the Company and its
         Restricted Subsidiaries after the date hereof (excluding Restricted
         Payments permitted by clauses (2) and (3) of the next succeeding
         paragraph), is less than the sum, without duplication, of:

                           (a)      50% of the Consolidated Net Income of the
                  Company for the period (taken as one accounting period) from
                  the beginning of the first fiscal quarter commencing after
                  the date of this Indenture to the end of the Company's most
                  recently ended fiscal quarter for which financial statements
                  have been filed with the SEC in compliance with Section 4.03
                  at the time of such Restricted Payment (or, if such
                  Consolidated Net Income for such period is a deficit, less
                  100% of such deficit), plus

                           (b)      100% of the aggregate net cash proceeds
                  received by the Company since the date of this Indenture as a
                  contribution to its common equity capital or from the issue
                  or sale of Equity Interests of the Company (other than
                  Disqualified Stock) or from the issue or sale of convertible
                  or exchangeable Disqualified Stock or convertible or
                  exchangeable debt securities of the Company that have been
                  converted into or exchanged for such Equity Interests (other
                  than Equity Interests (or Disqualified Stock or debt
                  securities) sold to a Subsidiary of the Company); plus

                           (c)      to the extent that any Restricted
                  Investment that was made after the date hereof is sold for
                  cash or otherwise liquidated or repaid for cash, the lesser
                  of (i) the cash return of capital with respect to such
                  Restricted Investment (less the cost of disposition, if any)
                  and (ii) the initial amount of such Restricted Investment;
                  plus

                           (d)      $10.0 million.

                  So long as no Default has occurred and is continuing or would
be caused thereby, the preceding provisions 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

         for, or out of the net cash proceeds of the substantially concurrent
         sale (other than to a Subsidiary of the Company) of, Equity Interests
         of the Company (other than Disqualified Stock); provided that the
         amount of any such net cash proceeds that are utilized for any such
         redemption, repurchase, retirement, defeasance or other acquisition
         shall be excluded from clause (3) (b) of the preceding paragraph;

                  (3)      the defeasance, redemption, repurchase or other
         acquisition of subordinated Indebtedness of the Company or any

         Refinancing Indebtedness;

                  (4)      the payment of any dividend by a Restricted
         Subsidiary of the Company to the holders of its common Equity

                  (5)      the repurchase, redemption or other acquisition or
         retirement for value of any Equity Interests of the Company or any
         Subsidiary of the Company held by employees, former employees,
         officers, former officers, directors or former directors of the
         Company or any of its Subsidiaries (or the estates or beneficiaries of
         the estates of such employees, former employees, officers, former
         officers, directors or former directors) pursuant to any equity
         subscription agreement, stock option agreement, employment agreement,
         stock compensation plan or similar agreement approved by the Board of
         Directors, in an amount not to exceed $1.0 million in any calendar
         year; provided that the Company may carry over and make in a
         subsequent calendar year, in addition to the $1.0 million otherwise
         permitted for such calendar year, the amount of such purchases,
         redemptions or other acquisitions or retirements for value permitted
         to have been made but not made in any preceding calendar year;
         provided that the aggregate repurchases, redemptions or other
         acquisitions or retirements for value does not exceed $2.0 million in
         any calendar year;

                  (6)      repurchases of Equity Interests deemed to occur upon
         the exercise of stock options, if such Equity Interests represent a
         portion of the exercise price thereof and repurchases of Equity
         Interests deemed to occur upon the withholding of a portion of the
         Equity Interests granted or awarded to any employee to pay for the

                  (7)      the repurchase of any subordinated Indebtedness of
         the Company or any Guarantor at a purchase price not greater than 101%
         of the principal amount (or accreted value, if applicable) of such
         subordinated Indebtedness in the event of a Change of Control in
         accordance with provisions similar to those set forth in Section 4.15;
         provided that, prior to or simultaneously with such repurchase, the
         Company has made the Change of

                                      49

         Control Offer as provided in such Section 4.15 and has repurchased all
         Notes validly tendered for payment in connection with such Change of
         Control Offer.

                  The amount of all Restricted Payments (other than cash) shall
be 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 Company 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 shall be determined by the Board of Directors, whose resolution with
respect thereto shall be delivered to the Trustee. The Board of Directors'
determination must be based upon an opinion or appraisal issued by an
accounting, appraisal or investment banking firm of national standing if the
fair market value exceeds $10.0 million. Not later than the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth

Section 4.08      Dividend and Other Payment Restrictions Affecting Restricted
                  Subsidiaries.

                  The Company 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:

                  (a)      pay dividends or make any other distributions on its
         Capital Stock to the Company or any of its Restricted Subsidiaries, or
         with respect to any other interest or participation in, or measured
         by, its profits, or pay any indebtedness owed to the Company or any of
         its Restricted Subsidiaries;

                  (b)      make loans or advances to the Company or any of its
         Restricted Subsidiaries; or

         Company or any of its Restricted Subsidiaries.

                  However, the restrictions above shall not apply to
encumbrances or restrictions existing under or by reason of:

                  (1)      Existing Indebtedness, including the Credit
         Agreement, as in effect on the date of this Indenture and any
         amendments, modifications, restatements, renewals, increases,
         supplements, refundings, replacements or refinancings thereof,
         provided that such amendments, modifications, restatements, renewals,
         increases, supplements, refundings, replacements or refinancings, in
         the good faith judgment of the Board of Directors, are no more
         restrictive, taken as a whole, than those contained in such Existing
         Indebtedness, as in effect on the date of this Indenture;

                  (2)      this Indenture, the Notes and the Subsidiary
         Guarantees;

                                      50
<PAGE>

                  (3)      applicable law;

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

                  (5)      customary non-assignment provisions in leases,
         licenses or other contracts entered into in the ordinary course of
         business and consistent with past practices;

                  (6)      purchase money obligations for property acquired or
         constructed in the ordinary course of business that impose
         restrictions on the property so acquired or constructed of the nature
         described in clause (3) of the preceding paragraph;

                  (7)      any agreement for the sale or other disposition of a
         Restricted Subsidiary that restricts distributions by that Restricted
         Subsidiary pending its sale or other disposition;

                  (8)      Permitted Refinancing Indebtedness, provided that
         the restrictions contained in the agreements governing such Permitted
         Refinancing Indebtedness, in the good faith judgment of the Board of
         Directors, 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 provisions with respect to the disposition
         or distribution of assets or property in joint venture, limited
         liability company, operating, partnership, shareholder and other
         similar agreements entered into in the ordinary course of business
         with other significant equity investors in such entities;

                  (11)     restrictions on cash or other deposits or net worth
         imposed by customers under contracts entered into in the ordinary
         course of business; provided that the Company in good faith determines
         that such restrictions will not have a material adverse effect on the
         ability of the Company to pay principal, interest and premium on the
         Notes; and

                  (12)     Indebtedness of a Restricted Subsidiary that is a
         Guarantor, permitted to be incurred under Section 4.09; provided that
         such encumbrance or restriction is not applicable to the properties or
         assets of any Person other than such Guarantor.

Section 4.09      Incurrence of Indebtedness and Issuance of Preferred Stock.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "INCUR") any
Indebtedness (including Acquired Debt), and the Company will not issue any
Disqualified Stock, and the Company will not permit any of its Restricted
Subsidiaries to issue any Disqualified Stock or preferred stock; provided,
however, that the Company and any Guarantor may incur Indebtedness (including
Acquired Debt), and the Company may issue Disqualified Stock, if the Fixed
Charge Coverage Ratio for the Company's most recently ended four full fiscal
quarters for which financial statements have been filed with the SEC in
compliance with Section 4.03 immediately preceding the date on which such
additional Indebtedness is incurred, or such Disqualified Stock is issued,
would have been at least 2.25 to 1, determined on a pro forma basis (including
a pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred, or such Disqualified Stock had been issued, at
the beginning of such four-quarter period.

                  Notwithstanding the foregoing, so long as no Default shall
have occurred and be continuing or would be caused thereby, the first paragraph
of this Section 4.09 will not prohibit the incurrence of any of the following
items of Indebtedness (collectively, "PERMITTED DEBT"):

                  (1)      the incurrence by the Company or any Guarantor of
         Indebtedness under the Credit Agreement in an aggregate principal
         amount at any one time outstanding (with letters of credit being
         deemed to have a principal amount equal to the maximum potential
         liability thereunder) not to exceed the amount of all borrowings and
         commitments thereunder on the Closing Date, plus $10.0 million, less
         the aggregate amount of all Net Proceeds of Asset Sales applied by the
         Company or any of its Restricted Subsidiaries to repay such
         Indebtedness and to effect a corresponding commitment reduction
         thereunder pursuant to Section 4.10 hereof;

                  (2)      the incurrence by the Company and any Restricted
         Subsidiary of the Existing Indebtedness (including, without
         limitation, deferred purchase price obligations (whether or not
         contingent) under acquisition agreements in effect on the date of this
         Indenture);

                  (3)      the incurrence by the Company and the Guarantors of
         Indebtedness represented by the Notes and the related Subsidiary
         Guarantees to be issued on the date hereof and the Exchange Notes and
         the related Subsidiary Guarantees to be issued pursuant to the
         Registration Rights Agreement;

                  (4)      the incurrence by the Company or any Restricted
         Subsidiary of Indebtedness represented by Capital Lease Obligations,
         mortgage financings or purchase money obligations, in each case
         incurred for the purpose of financing all or any part of the purchase
         price or cost of construction or improvement of property, plant or
         equipment used in the business of the Company or such Restricted
         Subsidiary, in an aggregate principal amount, including all Permitted
         Refinancing Indebtedness incurred to refund,

                                      52
<PAGE>

         refinance or replace any Indebtedness incurred pursuant to this clause
         (4), not to exceed $10.0 million at any time outstanding;

                  (5)      the incurrence by the Company or any of the
         Restricted Subsidiary of Permitted Refinancing Indebtedness in
         exchange for, or the net proceeds of which are used to refund,
         refinance or replace Indebtedness (other than intercompany
         Indebtedness) that was permitted to be incurred under the first
         paragraph of this Section 4.09 or clauses (2), (3), (4), or (14) of
         this paragraph;

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

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

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

                  (7)      the incurrence by the Company or any of its
         Restricted Subsidiaries of Hedging Obligations under or with respect
         to (a) Interest Rate Agreements not for the purpose of speculation and
         (b) Currency Agreements entered into in the ordinary course of
         business and not for the purpose of speculation;

                  (8)      the guarantee by the Company or any of the
         Guarantors of Indebtedness of the Company or a Restricted Subsidiary
         that was permitted to be incurred by another provision of this Section
         4.09;

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

                  (10)     the incurrence of Indebtedness of the Company or any
         Restricted Subsidiary in respect of performance bonds and surety or
         appeal bonds entered into by the Company or such Restricted Subsidiary
         in the ordinary course of business;

                                      53
<PAGE>

                  (11)     the incurrence of Indebtedness of the Company or any
         Restricted Subsidiary arising from the honoring by a bank or other
         financial institution of a check, draft or similar instrument
         inadvertently (except in the case of daylight overdrafts) drawn
         against insufficient funds in the ordinary course of business,
         provided that such Indebtedness is satisfied within 3 business days of
         incurrence;

                  (12)     the incurrence of Indebtedness of the Company or any
         Restricted Subsidiary represented by letters of credit for the account
         of the Company or such Restricted Subsidiary, as the case may be, in
         order to provide security for workers' compensation claims, payment
         obligations in connection with self-insurance programs or similar
         requirements in the ordinary course of business;

                  (13)     endorsements in the ordinary course of business of
         negotiable instruments for deposit or collection;

                  (14)     the incurrence by the Company or any Restricted
         Subsidiary of additional Indebtedness in an aggregate principal amount
         (or accreted value, as applicable) at any time outstanding, not to
         exceed $10.0 million.

                  For purposes of determining compliance with this Section
4.09, 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
(13) above, or is entitled to be incurred pursuant to the first paragraph of
this Section 4.09, the Company will be permitted to classify such item of
Indebtedness on the date of its incurrence and, from time to time, reclassify
all or a portion of such item of Indebtedness, in any manner that complies with
this Section 4.09. Notwithstanding the foregoing, Indebtedness under Credit
Facilities outstanding on the date on which Notes are first issued and
authenticated hereunder shall be deemed to have been incurred on such date in
reliance on the exception provided by clause (1) of the definition of Permitted

                  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless:

                  (a)      the Company (or the Restricted Subsidiary, as the
         case may be) receives consideration at the time of the Asset Sale at
         least equal to the fair market value (including the value of all
         non-cash consideration) of the assets or Equity Interests issued or
         sold or otherwise disposed of;

                  (b)      such fair market value is determined by the
         Company's Board of Directors and evidenced by a resolution of the
         Board of Directors set forth in an Officers' Certificate delivered to
         the Trustee (or determined by the Company and evidenced by an
         Officers' Certificate delivered to the Trustee in the case of an Asset
         Sale with a fair market value of less than $2.5 million); and

                                      54
<PAGE>

                  (c)      at least 75% of the consideration therefor received
         by the Company or such Restricted Subsidiary is in the form of (i)
         cash or Cash Equivalents or (ii) Replacement Assets or a combination
         thereof. For purposes of this Section 4.10, each of the following
         shall be deemed to be cash:

                           (1)      any liabilities (as shown on the Company's
                  or such Restricted Subsidiary's most recent balance sheet) of
                  the Company or any Restricted Subsidiary (other than
                  liabilities that are by their terms subordinated to the Notes
                  or any Subsidiary Guarantee) that are assumed by the
                  transferee of any such assets pursuant to a customary written
                  novation agreement that releases the Company or such
                  Restricted Subsidiary from further liability; and

                           (2)      any securities, notes or other obligations
                  received by the Company or any such Restricted Subsidiary
                  from such transferee that are promptly converted by the
                  Company or such Restricted Subsidiary into cash or Cash
                  Equivalents (to the extent of the cash or Cash Equivalents
                  received in that conversion).

                  Within 360 days after the receipt of any Net Proceeds from an
Asset Sale, the Company may apply such Net Proceeds at its option: (i) to repay
Senior Debt and to correspondingly reduce commitments with respect thereto;
(ii) to acquire all or substantially all of the assets of, or a majority of the
Voting Stock of, another Permitted Business; (iii) to make a capital
expenditure in or that is used or useful in a Permitted Business; or (iv) to
acquire other long-term assets in or that are used or useful in a Permitted
Business.

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

                  Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the preceding paragraph will constitute "EXCESS
Proceeds." When the aggregate amount of Excess Proceeds exceeds $5.0 million,
the Company will make an offer to purchase (an "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 as may be purchased out of the Excess Proceeds. The offer price in
any Asset Sale Offer will be equal to 100% of principal amount plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(or, in respect of such other pari passu Indebtedness, such lesser price, if
any, as may be provided for by the terms of such Indebtedness), and will be
payable in cash (or, in respect of such other pari passu Indebtedness, in cash
and/or such other property, if any, as may be provided for or permitted by the
terms of such Indebtedness). If any Excess Proceeds remain after consummation
of an Asset Sale Offer, the Company 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 Trustee shall select the
Notes and such other pari passu Indebtedness to be purchased on a pro rata
basis based on the principal amount of Notes and such other pari

                                      55
<PAGE>

passu Indebtedness tendered. Upon completion of each Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero.

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

Section 4.11      Transactions with Affiliates.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "AFFILIATE TRANSACTION"), unless:

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

                  (2)      the Company delivers to the Trustee:

                           (a)      with respect to any Affiliate Transaction
                  or series of related Affiliate Transactions involving
                  aggregate consideration in excess of $2.5 million, a
                  resolution of the Board of Directors set forth in an
                  Officers' Certificate certifying that such Affiliate
                  Transaction complies with this Section and that such
                  Affiliate Transaction has been approved by a majority of the
                  disinterested members of the Board of Director; and

                           (b)      with respect to any Affiliate Transaction
                  or series of related Affiliate Transactions involving
                  aggregate consideration in excess of $5.0 million, an opinion
                  as to the fairness to the Company or such Restricted
                  Subsidiary of such Affiliate Transaction from a financial
                  point of view issued by an accounting, appraisal or
                  investment banking firm of national standing.

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

                  (1)      transactions solely between or among the Company
         and/or its Restricted Subsidiaries;

                  (2)      payment of reasonable directors fees;

                                      56
<PAGE>

                  (3)      transactions provided for in the Approved Affiliate
         Agreements as in effect on the Closing Date;

                  (4)      the issuance or sale of any Equity Interests (other
         than Disqualified Stock) of the Company;

                  (5)      the payment of fees, compensation or employee
         benefits to, and indemnity provided for the benefit of, directors,
         officers or employees of the Company or any Restricted Subsidiary
         (other than the Principal or a Related Party of the Principal) in the
         ordinary course of business if approved by a majority of the
         disinterested members of the Board of Directors or the Compensation
         Committee thereof; and

                  (6)      Restricted Payments that are permitted by Section
         4.07 of this Indenture.

Section 4.12      Liens.

                  The Company will not, and will 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,
Attributable Debt or trade payables (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 until such time as such obligations are
no longer secured by a Lien.

Section 4.13      Business Activities.

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

Section 4.14      Limitation on Senior Subordinated Debt.

                  The Company will not incur, create, issue, assume, guarantee
or otherwise become liable for any Indebtedness that is subordinate or junior
in right of payment to any Senior Debt of the Company and senior in any respect
in right of payment to the Notes. No Guarantor will incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to the Senior Debt of such Guarantor
and senior in any respect in right of payment to such Guarantor's Subsidiary
Guarantee.

Section 4.15 Offer to Repurchase upon a Change of Control.

                  Upon the occurrence of a Change of Control, each Holder of
Notes shall have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount thereof
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
date of purchase (the "Change of Control Payment"). Within 10 days following
any Change of Control, the Company

                                      57
<PAGE>

shall mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and stating (1) that the Change of
Control Offer is being made pursuant to this Section 4.15 and that all Notes
tendered will be accepted for payment; (2) the purchase price and the purchase
date, which shall be no earlier than 30 days and no later than 60 days from the
date such notice is mailed (the "Change of Control Payment Date"); (3) that any
Note not tendered will continue to accrue interest; (4) that, unless the
Company defaults in the payment of the Change of Control Payment, all Notes
accepted for payment pursuant to the Change of Control Offer shall cease to
accrue interest after the Change of Control Payment Date; (5) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer will
be required to surrender the Notes, with the form entitled "Option of Holder to
Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at
the address specified in the notice prior to the close of business on the third
Business Day preceding the Change of Control Payment Date; (6) that Holders
will be entitled to withdraw their election if the Paying Agent receives, not
later than the close of business on the second Business Day preceding the
Change of Control Payment Date, a telegram, telex, facsimile transmission or
letter setting forth the name of the Holder, the principal amount of Notes
delivered for purchase, and a statement that such Holder is withdrawing his
election to have the Notes purchased; and (7) that Holders whose Notes are
being purchased only in part will be issued new Notes equal in principal amount
to the unpurchased portion of the Notes surrendered, which unpurchased portion
must be equal to $1,000 in principal amount or an integral multiple thereof.
The Company shall comply with the requirements of Rule 14e-1 under the Exchange
Act and any other securities laws and regulations thereunder to the extent such
laws and regulations are applicable in connection with the repurchase of the
Notes as a result of a Change of Control. To the extent that the provisions of
any securities laws or regulations conflict with the provisions of this
Indenture relating to such Change of Control Offer, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations described in this Indenture by virtue thereof.

                  (b)      On the Change of Control Payment Date, the Company
shall, to the extent lawful, (1) accept for payment all Notes or portions
thereof properly tendered pursuant to the Change of Control Offer, (2) deposit
with the Paying Agent an amount equal to the Change of Control Payment in
respect of all Notes or portions thereof so tendered and (3) deliver or cause
to be delivered to the Trustee the Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company. The Paying Agent shall promptly mail to each
Holder of Notes so tendered the Change of Control Payment for such Notes and,
pursuant to the Officer's Certificate, the Trustee shall promptly authenticate
and mail (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered,
if any; provided that each such new Note shall be in a principal amount of
$1,000 or an integral multiple thereof. Prior to compliance with this Section
4.15, but in any event within 90 days following a Change of Control, the
Company shall 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 4.15. The Company shall
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

<PAGE>

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

Section 4.16      Limitation on Issuances and Sales of Equity Interests in
                  Restricted Subsidiaries.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, transfer, convey, sell or otherwise dispose of any
Equity Interests in any Restricted Subsidiary of the Company to any Person
(other than the Company or a Wholly Owned Restricted Subsidiary of the
Company); provided, however, that this Section 4.16 will not prohibit:

                  (1)      the sale or other disposition of all, but not less
         than all, of the issued and outstanding Equity Interests of a
         Restricted Subsidiary owned by the Company and its Restricted
         Subsidiaries, if such owner applies the Net Cash Proceeds of any such
         sale in accordance with Section 4.10;

                  (2)      the sale or other disposition of a portion of the
         issued and outstanding Equity Interests of a Restricted Subsidiary
         (provided that, with respect to any Guarantor, such Equity Interests
         are in the form of Common Stock), whether or not as a result of such
         sale or disposition such Restricted Subsidiary continues or ceases to
         be a Restricted Subsidiary, if (A) at the time of such sale or
         disposition, the Company could make an Investment in the remaining
         Equity Interests held by it or one of its Restricted Subsidiaries in
         an amount equal to the amount of its remaining Investment in such
         Person pursuant to Section 4.07 and (B) the Company and/or such
         Restricted Subsidiaries applies the Net Cash Proceeds of any such sale
         in accordance with Section 4.10; or

                  (3)      transfers, conveyances, sales or other dispositions
         (A) to directors of director's qualifying shares or (B) of shares of
         Restricted Subsidiaries required by applicable law to be owned by
         foreign nationals.

Section 4.17      Designation of Restricted and Unrestricted Subsidiaries.

                  The Board of Directors may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause
a Default. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate fair market value of all outstanding Investments
owned by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be a Restricted Investment made as of the time of
such designation and that designation will 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 Company 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 Company of any
outstanding Indebtedness of such Unrestricted Subsidiary and such designation
shall only be permitted if (1) such Indebtedness is permitted under Section
4.09, calculated on a pro forma basis as if such

                                      59
<PAGE>

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 4.18      Payments for Consent.

                  The Company will not, and will 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      Limitations on Issuances of Guarantees of Indebtedness.

                  The Company will 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 Company unless such
Restricted Subsidiary is a Guarantor or simultaneously executes and delivers a
supplemental indenture 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.

                  Notwithstanding the preceding paragraph, any Subsidiary
Guarantee will provide by its terms that it will be automatically and
unconditionally released and discharged under the circumstances described in
Section 11.06. The form of the Subsidiary Guarantee is attached as Exhibit F.

Section 4.20      Sale and Leaseback Transactions.

                  The Company will not, and will not permit any of its
Restricted Subsidiaries to, enter into any sale and leaseback transaction other
than among the Company and its Wholly-Owned Restricted Subsidiaries; provided
that the Company or any Restricted Subsidiary may enter into a sale and
leaseback transaction if:

                  (1)      the Company or that Restricted Subsidiary, as
         applicable, could have incurred Indebtedness in an amount equal to the
         Attributable Debt relating to such sale and leaseback transaction
         under the Fixed Charge Coverage Ratio test in the first paragraph of
         Section 4.09;

                  (2)      the gross cash proceeds of that sale and leaseback
         transaction are at least equal to the fair market value, as determined
         in good faith by the Board of Directors and set forth in an Officers'
         Certificate delivered to the Trustee (or as determined in good faith
         by the Company in the case of a sale and leaseback transaction
         resulting in gross cash proceeds of less than $2.5 million), of the
         property that is the subject of that sale and leaseback transaction;
         and

                                      60
<PAGE>

                  (3)      the transfer of assets in that sale and leaseback
         transaction is permitted by, and the Company applies the proceeds of
         such transaction in compliance with, Section 4.10.

Section 4.21      Additional Subsidiary Guarantees.

                  If the Company or any of its Restricted Subsidiaries acquires
or creates another Domestic Subsidiary on or after the date of this Indenture
and 80% or more of the Equity Interests of such newly acquired or created
Domestic Subsidiary is owned by the Company and/or any of its Restricted
Subsidiaries, then that newly acquired or created Domestic Subsidiary must
become a Guarantor and execute a supplemental indenture (in the form of Exhibit
F hereto providing for the Guarantee of the payment of the Notes by such
Domestic Subsidiary on the same basis as the Guarantors at the time of the
execution of such supplemental indenture) and deliver an Opinion of Counsel to
the Trustee within 10 Business Days of the date on which it was acquired or
created.

dispose of all or substantially all of the properties or assets of the Company
and its Subsidiaries taken as a whole, in one or more related transactions, to
another Person; unless:

         sale, assignment, transfer, conveyance or other disposition shall have
         been made is a corporation organized or existing under the laws of the

         consolidation or merger (if other than the Company) or the Person to
         which such sale, assignment, transfer, conveyance or other disposition
         shall have been made assumes all the obligations of the Company under
         the Notes, this Indenture and the Registration Rights Agreement
         pursuant to agreements reasonably satisfactory to the Trustee;

                  (3)      immediately after such transaction no Default or
         Event of Default exists; and

                  (4)      the Company or the Person formed by or surviving any
         such consolidation or merger (if other than the Company), or to which
         such sale, assignment, transfer, conveyance or other disposition shall
         have been made: (a) will have a Consolidated Net

         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, be permitted to incur at least $1.00 of
         additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
         test set forth in the first paragraph of Section 4.09.

                  In addition, neither the Company nor any Restricted
Subsidiary may, directly or indirectly, lease all or substantially all of its
properties or assets, in one or more related transactions, to any other Person.
This Section 5.01 will not apply to a sale, assignment, transfer, conveyance or
other disposition of assets between or among the Company and any of its
Restricted Subsidiaries.

                  Each of the following is an Event of Default:

                  (1)      default for 30 days in the payment when due of
         interest on, or Liquidated Damages with respect to, the Notes whether
         or not prohibited by the subordination provisions of this Indenture;

                  (2)      default in payment when due of the principal of, or
         premium, if any, on the Notes, whether or not prohibited by the
         subordination provisions of this Indenture;

                  (3)      failure by the Company or any of its Restricted
         Subsidiaries to comply with the provisions described in Sections 3.09,

                  (4)      failure by the Company or any of its Restricted
         Subsidiaries for 60 days after receipt of notice from the Trustee or

         outstanding to comply with any of the other agreements in this
         Indenture;

                  (5)      default under any mortgage, indenture or instrument
         under which there may be issued or by which there may be secured or

         its Restricted Subsidiaries (or the payment of which is guaranteed by
         the Company 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 pay principal of,
                  or interest or premium, if any, on such Indebtedness prior to
                  the expiration of the grace period provided in such
                  Indebtedness on the date of such default (a "PAYMENT
                  DEFAULT") and the amount of such Indebtedness aggregates $5.0
                  million or more; or

                                      62

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

         and, in either case, the principal amount of any such Indebtedness,
         the maturity of which has been accelerated, together with the amount
         of any Payment Default, exceeds $5.0 million;

                  (6)      failure by the Company or any of its Restricted
         Subsidiaries to pay final judgments (other than judgments which are
         covered by enforceable insurance policies issued by reputable carriers
         and as to which such insurers have acknowledged liability in writing)
         aggregating in excess of $5.0 million, which judgments are not paid,
         discharged or stayed for a period of 60 days;

                  (7)      except as permitted this Indenture, any Subsidiary
         Guarantee shall be held in any judicial proceeding to be unenforceable
         or invalid or shall cease for any reason to be in full force and
         effect or any Guarantor, or any Person acting on behalf of any
         Guarantor, shall deny or disaffirm its obligations under its
         Subsidiary Guarantee;

                  (8)      the Company or any of its Significant Subsidiaries,
         pursuant to or within the meaning of Bankruptcy Law:

                  (i)      commences a voluntary case,

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

                  (iii)    makes a general assignment for the benefit of its
         creditors, or

                  (iv)     generally is not paying its debts as they become
         due; and

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

                           (i)      is for relief against the Company or any of
                  its Significant Subsidiaries, in an involuntary case;

                           (ii)     appoints a custodian of the Company or any
                  of its Significant Subsidiaries or for all or substantially
                  all of the property of the Company or any of its Significant

                  any of its Significant Subsidiaries;

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

Section 6.02      Acceleration.

                  If any Event of Default (other than an Event of Default
specified in clause (8) or (9) of Section 6.01) occurs and is continuing, the
Trustee or the Holders of at least 25% in

                                      63
<PAGE>

principal amount of the then outstanding Notes may declare all principal,
premium, if any, accrued interest and Liquidated Damages, if any, of the Notes
to be due and payable immediately. Upon any such declaration, the Notes shall
become due and payable immediately. If any Event of Default specified in clause
(8) or (9) of Section 6.01 occurs and is continuing, then the principal,
premium, if any, accrued interest and Liquidated Damages, if any, on the Notes
shall ipso facto become and be immediately due and payable without any
declaration or other action on the part of the Trustee or any Holder.

                  If any Event of Default occurs by reason of any willful
action or inaction taken or not taken by the Company or on its behalf with the
intention of avoiding payment of the premium that the Company would have had to
pay if it then had elected to redeem the Notes pursuant to Section 3.07 hereof,
then, upon acceleration of the Notes, an equivalent premium shall also become
and be immediately due and payable, to the extent permitted by law, anything in
this Indenture or in the Notes to the contrary notwithstanding. If an Event of
Default occurs during any time that the Notes are outstanding, by reason of any
willful action (or inaction) taken (or not taken) by or on behalf of the
Company with the intention of avoiding the prohibition on redemption of the
Notes, then, the premium specified in this Indenture shall also become
immediately due and payable to the extent permitted by law upon the
acceleration of the Notes.

Section 6.03      Other Remedies.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of principal, premium,
if any, interest, and Liquidated Damages, if any, with respect to, the Notes or
to enforce the performance of any provision of the Notes or this Indenture. In
addition, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount as shall
be sufficient to cover the reasonable out-of-pocket costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

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

Section 6.04      Waiver of Past Defaults.

                  Holders of 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 an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of interest or Liquidated Damages on, or the principal of, the Notes
(including in connection with an offer to purchase) (provided, however, that
the Holders of a majority in principal amount of the then outstanding Notes may
rescind an acceleration and its consequences, including any related payment
default that resulted from such acceleration). The Company shall deliver to the
Trustee an Officers' Certificate stating that the requisite percentage of
Holders have consented to such waiver and attaching copies of such consents. In
case of any

                                      64
<PAGE>

such waiver, the Company, the Trustee and the Holders shall be restored to
their former positions and rights hereunder and under the Notes, respectively.
This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such
Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this
Indenture and the Notes, as permitted by the TIA. Upon any such waiver, such
Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured for every purpose of this Indenture; but no such
waiver shall extend to any subsequent or other Default or impair any right
consequent thereon.

Section 6.05      Control by Majority.

                  Holders of a majority in principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability. The Trustee may withhold from
Holders of the Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal or
interest or Liquidated Damages) if it determines that withholding notice is in
their interest.

Section 6.06      Limitation on Suits.

                  A Holder may pursue a remedy with respect to this Indenture,
or the Notes or the Subsidiary Guarantees only if:

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

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

                  (c)      such Holder of a Note or Holders of Notes offer and,
         if requested, provide to the Trustee security and indemnity
         satisfactory to the Trustee against any loss, liability or expense
         that might be incurred by it in connection with the request or
         direction;

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

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

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

Section 6.07      Rights of Holders of Notes to Receive Payment.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, premium, if any,
interest on, and Liquidated Damages, if

                                      65
<PAGE>

any, with respect to, the Note, on or after the respective due dates expressed
in the Note (including in connection with an offer to purchase), or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

Section 6.08      Collection Suit by Trustee.

                  If an Event of Default specified in Section 6.01(1) or (2)
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as trustee of an express trust against the Company for the whole
amount of principal of, premium, if any, interest, and Liquidated Damages, if
any, remaining unpaid on the Notes and interest on overdue principal and
premium, if any, and, to the extent lawful, interest and Liquidated Damages, if
any, 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 is authorized to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel)
and the Holders of the Notes allowed in any judicial proceedings relative to
the Company or any Guarantor (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other securities or property payable or
deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee, and in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due to it
for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.07 hereof out of the
estate in any such proceeding, shall be denied for any reason, payment of the
same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Holder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or the rights of any
Holder, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

Section 6.10      Priorities.

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

                                      66
<PAGE>

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

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

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

                  The Trustee may fix a record date and payment date for any
payment to Holders of Notes pursuant to this Section 6.10.

Section 6.11      Undertaking for Costs.

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

                                 ARTICLE SEVEN
                                    TRUSTEE

Section 7.01      Duties of Trustee.

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

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

                  (i)      the duties of the Trustee shall be determined solely
         by the express provisions of this Indenture and the Trustee need
         perform only those duties that are specifically set forth in this
         Indenture and no others, and no implied covenants or obligations shall
         be read into this Indenture against the Trustee; and

                  (ii)     in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions, directions, and notices expressed
         therein, upon certificates or opinions furnished to the Trustee and
         conforming to the requirements of this Indenture. However, the Trustee
         shall examine

                                      67
<PAGE>

         the certificates and opinions to determine whether or not they conform
         to the requirements of this Indenture.

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

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

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

                  (iii)    the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with any
         directions, certificates or other notices received by it pursuant to
         this Indenture.

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

                  (e)      No provision of this Indenture shall require the
Trustee to expend or risk its own funds or incur any liability. The Trustee
shall be under no obligation to exercise any of its rights and powers under
this Indenture at the request of any Holders, unless such Holder shall have
offered to the Trustee security and indemnity satisfactory to it against any
loss, costs, liability or expense that might be incurred by it in connection
with the request or direction.

                  (f)      Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

Section 7.02      Certain Rights of Trustee.

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

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

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

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

<PAGE>

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

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

                  (g)      The Trustee shall not be deemed to have notice of
any Default or Event of Default unless a Responsible Officer of the Trustee has
actual knowledge thereof or unless written notice of such event is sent to the
Trustee in accordance with Section 13.02 hereof, and such notice references the
Notes.

                  (h)      Whether or not therein expressly so provided, every
provision of this Indenture that in any way relates to the Trustee is subject
to provisions of this Section 7.02.

Section 7.03      Individual Rights of Trustee.

                  The Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may become a creditor of, or otherwise
deal with, the Company or any of its Affiliates with the same rights it would
have if it were not Trustee. However, in the event that the Trustee acquires
any conflicting interest as described in the Trust Indenture Act of 1939, it
must eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

Section 7.04      Trustee's Disclaimer.

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

Section 7.05      Notice of Defaults.

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

Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA ss. 313(a) (but if no event described in
TIA ss. 313(a) has occurred within the twelve months preceding the reporting
date, no report need be transmitted). The Trustee also shall comply with TIA
ss. 313(b)(2). The Trustee shall also transmit by mail all reports as required
by TIA ss. 313(c).

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

Section 7.07      Compensation and Indemnity.

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

                  The Company shall indemnify, defend and hold harmless the
Trustee against any and all losses, liabilities or expenses incurred by it
arising out of or in connection with the acceptance or administration of its
duties under this Indenture, including the reasonable costs and expenses
actually incurred of enforcing this Indenture against the Company (including
this Section 7.07) and defending itself against any claim (whether asserted by
either of the Company or any Holder or any other person) or liability in
connection with the exercise or performance of any of its powers or duties
hereunder, except to the extent any such loss, liability or expense may be
attributable to its negligence, willful misconduct or bad faith. The Trustee
shall notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company
of its obligations hereunder. The Company shall defend the claim and the
Trustee shall cooperate in the defense. The Trustee may have separate counsel
and the Company shall pay the reasonable fees and expenses of such counsel. The
Company need not pay for any settlement made without its consent, which consent
shall not be unreasonably withheld.

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

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

                  When the Trustee incurs expenses or renders services after an
Event of Default specified in Section 6.01(8) or Section 6.01(9) hereof occurs,
the expenses and the compensation for the services (including the fees and
expenses of its agents and counsel) are intended to constitute expenses of
administration under any Bankruptcy Law.

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

Section 7.08      Replacement of Trustee.

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

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

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

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

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

                  (d)      the Trustee becomes incapable of acting.

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

                  If a successor Trustee does not take office within 30 days
after the retiring Trustee resigns or is removed, the retiring Trustee, the
Company, or the Holders of Notes of at least 10% in principal amount of the
then outstanding Notes may petition at the expense of the Company any court of
competent jurisdiction for the appointment of a successor Trustee.

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

                  A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all
property held by it as

                                      71
<PAGE>

Trustee to the successor Trustee, provided all sums owing to the Trustee
hereunder have been paid and subject to the Lien provided for in Section 7.07
hereof. Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 hereof shall continue for
the benefit of the retiring Trustee.

Section 7.09      Successor Trustee by Merger, Etc.

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

Section 7.10      Eligibility; Disqualification.

                  There shall at all times be a Trustee hereunder that is a
corporation or banking association organized and doing business under the laws
of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate trustee power, that is subject to
supervision or examination by federal or state authorities and that has a
combined capital and surplus of at least $100.0 million as set forth in its
most recent published annual report of condition.

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

Section 7.11      Preferential Collection of Claims Against Company.

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

                                 ARTICLE EIGHT
                       DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01      Option to Effect Legal Defeasance or Covenant Defeasance.

                  The Company may, at its option and at any time, elect to have
either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon
compliance with the conditions set forth below in this Article Eight.

Section 8.02      Legal Defeasance and Discharge.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.02, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from its obligations with respect to all outstanding Notes
and all obligations of the Guarantors shall be deemed to have been discharged
with respect to their obligations under the Subsidiary Guarantees on the date
the conditions set forth below are satisfied (hereinafter, "LEGAL DEFEASANCE").
For this purpose, Legal Defeasance means that the Company and the Guarantors
shall be deemed to have paid and discharged the

                                      72
<PAGE>

entire Indebtedness represented by the outstanding Notes and Subsidiary
Guarantees, respectively, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 8.05 hereof and the other Sections of this
Indenture referred to in (a) and (b) below, 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 Company, shall execute proper instruments
acknowledging the same), except for the following provisions which shall
survive until otherwise terminated or discharged hereunder:

                  (a)      the rights of Holders of outstanding Notes to
         receive payments in respect of the principal of, or interest or
         premium and Liquidated Damages, if any, on such Notes when such
         payments are due from the trust referred to in Section 8.04,

                  (b)      the Company's obligations with respect to such Notes
         under Article Two and Section 4.02 hereof,

                  (c)      the rights, powers, trusts, duties and immunities of
         the Trustee hereunder and the Company's obligations in connection
         herewith, and

                  (d)      this Article Eight.

                  Subject to compliance with this Article Eight, the Company
may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof.

Section 8.03      Covenant Defeasance.

                  Upon the Company's exercise under Section 8.01 hereof of the
option applicable to this Section 8.03, the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be released
from its obligations under the covenants contained in Sections 4.03, 4.05,
4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19,
4.20 and 4.21, hereof and the limitations set forth in Section 5.01(4) with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.04 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 Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section 6.01
hereof, but, except as specified above, the remainder of this Indenture and
such Notes shall be unaffected thereby. In addition, upon the Company's
exercise under Section 8.01 hereof of the option applicable to this Section
8.03, subject to the satisfaction of the conditions set forth in Section 8.04
hereof, Sections 6.01(3) though (7) shall not constitute Events of Default.

Section 8.04      Conditions to Legal or Covenant Defeasance.

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

                  (a)      the Company must irrevocably deposit with the
         Trustee, in trust, for the benefit of the Holders of the Notes, cash
         in U.S. dollars, 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, premium and Liquidated Damages, if any,
         on the outstanding Notes on the stated maturity or on the applicable
         redemption date, as the case may be, and the Company must specify
         whether the Notes are being defeased to maturity or to a particular
         redemption date;

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

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

                  (d)      no Default or Event of Default shall have occurred
         and is continuing either (i) on the date of such deposit or (ii)
         insofar as Section 6.01(8) or Section 6.01(9) hereof are concerned, at
         any time in the period ending on the 91st day after the date of
         deposit;

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

                  (f)      the Company must have delivered to the Trustee an
         Opinion of Counsel to the effect that, assuming no intervening
         bankruptcy of the Company or any Guarantor between the date of deposit
         and the 91st day following the deposit and assuming that no Holder is
         an "insider" of the Company under applicable bankruptcy law, after the
         91st day following the deposit, the trust funds will not be subject to
         the effect of any applicable

                                      74
<PAGE>

         bankruptcy, insolvency, reorganization or similar laws affecting
         creditors' rights generally under any applicable United States or
         state law;

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

                  (h)      the Company 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.

Section 8.05      Deposited Money and Government Securities to Be Held in
                  Trust; Other Miscellaneous Provisions.

                  Subject to Section 8.06 hereof, all money and non-callable
Government Securities (including the proceeds thereof) deposited with the
Trustee (or other qualifying trustee, collectively for purposes of this Section
8.05, the "TRUSTEE") pursuant to Section 8.04 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal,
premium and Liquidated Damages, if any, and interest, but such money need not
be segregated from other funds except to the extent required by law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the cash or
non-callable Government Securities deposited pursuant to Section 8.04 hereof or
the principal and interest received in respect thereof other than any such tax,
fee or other charge which by law is for the account of the Holders of the
outstanding Notes.

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

Section 8.06      Repayment to the Company.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of, premium
and Liquidated Damages, if any, or interest on any Note and remaining unclaimed
for two years after such principal and Liquidated Damages, if any, or interest
has become due and payable shall be paid to the Company on its request or (if
then held by the Company) shall be discharged from such trust; and the Holder
of such Note shall thereafter look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability

                                      75
<PAGE>

of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in the
New York Times and The Wall Street Journal (national edition), notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining shall be repaid to the Company.

Section 8.07      Reinstatement.

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

                                 ARTICLE NINE
                        AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01      Without Consent of Holders of Notes.

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

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

                  (b)      to provide for uncertificated Notes in addition to
         or in place of Definitive Notes;

                  (c)      to provide for the assumption of the Company's or
         any Guarantor's obligations to the Holders of the Notes in the case of
         a merger or consolidation or sale of all or substantially all of the
         Company's or such Guarantor's assets;

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

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

                                      76
<PAGE>

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

Section 9.02      With Consent of Holders of Notes.

                  Except as provided below in this Section 9.02, this Indenture
or the Notes may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Notes), and, subject to Sections
6.04 and 6.07 hereof, any existing Default or Event of Default or compliance
with any provision of this Indenture or the Notes may be waived with the
consent of the Holders of a majority in principal amount of the then
outstanding Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, Notes).

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date, or its duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental indenture, whether or not such Holders
remain Holders after such record date; provided that unless such consent shall
have become effective by virtue of the requisite percentage having been
obtained prior to the date which is 90 days after such record date, any such
consent previously given shall automatically and without further action by any
Holder be cancelled and of no further effect.

                  Upon the request of the Company accompanied by a resolution
of its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon the filing with the Trustee of evidence
satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in
Section 9.06 hereof, the Trustee shall join with the Company in the execution
of such amended or supplemental Indenture unless such amended or supplemental
Indenture directly affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise, in which case the Trustee may in its discretion,
but shall not be obligated to, enter into such amended or supplemental
Indenture.

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

                  After an amendment, supplement or waiver under this Section
becomes effective, the Company shall mail to the Holders of Notes affected
thereby a notice briefly describing the amendment, supplement or waiver. Any
failure of the Company to mail such notice, or any

                                      77
<PAGE>

defect therein, shall not, however, in any way impair or affect the validity of
any such amended or supplemental Indenture or waiver. Subject to Sections 6.04
and 6.07 hereof, the Holders of a majority in aggregate principal amount of the
then outstanding Notes may waive compliance in a particular instance by the
Company with any provision of this Indenture, or the Notes. However, without
the consent of each Holder affected, an amendment or waiver under this Section
9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

                  (b)      reduce the principal of or change the fixed maturity
         of any Note or alter the provisions or waive any payment with respect
         to the redemption of the Notes;

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

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

                  (e)      make any Note payable in money other than U.S.
         dollars;

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

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

                  (h)      impair the right to institute suit for the
         enforcement of any payment on or with respect to the Notes or the
         Subsidiary Guarantees;

                  (i)      amend, change or modify the obligation of the

         Company to make and consummate a Change of Control Offer in the event
         of a Change of Control in accordance with Section 4.15, including, in
         each case, amending, changing or modifying any definition relating
         thereto;

                  (j)      except as otherwise permitted under Article Five,
         consent to the assignment or transfer by the Company or any Guarantor
         of any of their rights or obligations under this Indenture;

                  (k)      amend or modify any of the provisions of this
         Indenture or the related definitions affecting the subordination or

<PAGE>

                  (l)      make any change in the preceding amendment and
         waiver provisions.

Section 9.03      Compliance with Trust Indenture Act.

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

Section 9.04      Revocation and Effect of Consents.

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

Section 9.05      Notation on or Exchange of Notes.

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

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

Section 9.06      Trustee to Sign Amendments, Etc.

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

                                  ARTICLE TEN
                                 SUBORDINATION

Section 10.01     Agreement to Subordinate.

                  The Company agrees, and each Holder by accepting a Note
agrees, that the payment of principal, interest and premium and Liquidated
Damages, if any, and other payment obligations on, or with respect to, the
Notes (including any obligation to repurchase the Notes) is

                                      79
<PAGE>

subordinated in right of payment, to the extent and in the manner provided in
this Article Ten, to the prior payment in full in cash of all Senior Debt
(whether outstanding on the date hereof or hereafter created, incurred, assumed
or guaranteed), and that the subordination is for the benefit of the holders of
Senior Debt.

Section 10.02     Liquidation; Dissolution; Bankruptcy.

                  The holders of Senior Debt of the Company will be entitled to
receive payment in full in cash of all Obligations due in respect of Senior
Debt of the Company (including interest after the commencement of any
bankruptcy proceeding at the rate specified in the applicable Senior Debt of
the Company) before the Holders of Notes will be entitled to receive any
payment 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 Eight hereof), in the event of any distribution to creditors of the
Company: (i) in a liquidation or dissolution of the Company; (ii) in a
bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Company or its property; (iii) in an assignment for the benefit
of creditors; or (iv) in any marshaling of the Company's assets and
liabilities.

Section 10.03     Default on Designated Senior Debt.

                  The Company may not make any payment in respect of the Notes
(except in Permitted Junior Securities or from the trust pursuant to Article
Eight hereof):

                  (a)      in the event of any default in the payment of
         principal of, interest or premium, if any, on any Designated Senior
         Debt, or any Obligation owing from time to time under or in respect of
         Senior Debt, or in the event that any default (other than a payment
         default) with respect to any Designated Senior Debt shall have
         occurred and be continuing and shall have resulted in such Designated
         Senior Debt becoming or being declared due and payable prior to the
         date on which it would otherwise have become due and payable; or

                  (b)      if any event of default other than as described in
         clause (a) above with respect to any Designated Senior Debt shall have
         occurred and be continuing permitting the holders of such Designated
         Senior Debt or the holders of any series thereof (or their
         Representative or Representatives) to declare such Designated Senior
         Debt due and payable prior to the date on which it would otherwise
         have become due and payable;

                           (1)      in case of any payment or nonpayment
                  default specified in clause (a), unless and until such
                  default shall have been cured or waived in writing in
                  accordance with the instruments governing such Designated
                  Senior Debt or such acceleration shall have been rescinded or
                  annulled, or

                           (2)      in case of any nonpayment default specified
                  in clause (b), during the period (a "PAYMENT BLOCKAGE
                  PERIOD") commencing on the date the Trustee receives written
                  notice (a "PAYMENT BLOCKAGE NOTICE") of such default from the
                  Company or a Representative of the holders of such Designated
                  Senior Debt (which notice shall be binding on the Company,
                  the Trustee and the Holders of Notes as to the occurrence of
                  such a nonpayment event of default) and ending on

                                      80
<PAGE>

                  the earlier of: the date on which such default is cured or
                  waived or 179 days after the date on which the applicable
                  Payment Blockage Notice is received, unless the maturity of
                  such Designated Senior Debt of the Company has been
                  accelerated.

                  No new Payment Blockage Notice may be delivered to the
Company or the Trustee that would start a new Payment Blockage Period unless
and until: (i) 360 days have elapsed since the delivery of the immediately
prior Payment Blockage Notice that started a Payment Blockage Period; and (ii)
all scheduled payments of principal, interest and premium and Liquidated
Damages, if any, on the Notes that have come due have been paid in full in
cash. No nonpayment event of default which existed or was continuing with
respect to the Designated Senior Debt on the date of delivery of any Payment
Blockage Notice to the Trustee shall be, or be made, the basis for the
commencement of any subsequent Payment Blockage Period unless such default has
been cured or waived for a period of not less than 90 days.

Section 10.04     Acceleration of Notes.

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

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

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

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

                                      81
<PAGE>

Section 10.07     Subrogation.

                  After all Senior Debt is paid in cash 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 Ten to holders of Senior Debt that otherwise would have been made to
Holders of Notes is not, as between the Company and Holders, a payment by the
Company on the Notes.

Section 10.08     Relative Rights.

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

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

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

                  (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 and owners of Senior Debt to receive
         distributions and payments otherwise payable to Holders of Notes.

                  If the Company fails because of this Article Ten to pay
principal of 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 Company.

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

Section 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 Company
referred to in this Article Ten, the Trustee and the Holders of Notes shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders of Notes for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of the Senior Debt
and other Indebtedness of the

                                      82
<PAGE>

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

Section 10.11     Rights of Trustee and Paying Agent.

                  Notwithstanding the provisions of this Article Ten 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 Ten. Only the
Company or a Representative may give the notice. Nothing in this Article Ten
shall impair the claims of, or payments to, the Trustee under or pursuant to
Section 7.07 hereof.

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

Section 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 Ten, 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 lenders under the Credit Agreement are hereby
authorized to file an appropriate claim for and on behalf of the Holders of the
Notes.

                                ARTICLE ELEVEN
                             SUBSIDIARY GUARANTEES

Section 11.01     Guarantee.

                  Subject to this Article Eleven each of the Guarantors hereby,
jointly and severally, unconditionally guarantees to each Holder of a Note
authenticated and delivered by the Trustee and to the Trustee and its
successors and assigns, irrespective of the validity and enforceability of this
Indenture, the Notes or the obligations of the Company hereunder or thereunder,
that: (a) the principal of and interest on the Notes will be promptly paid in
full when due, whether at maturity, by acceleration, redemption or otherwise,
and interest on the overdue principal of and interest on the Notes, if any, if
lawful (subject in all cases to any applicable grace period provided herein),
and all other obligations of the Company to the Holders or the Trustee
hereunder or thereunder will be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and (b) in case of any extension
of time of payment or renewal of any Notes or any of such other obligations,
the same will be promptly paid in full when due or performed in accordance with
the terms of the extension or renewal, subject to any applicable grace period,
whether at stated maturity, by acceleration or otherwise. Failing payment when

                                      83
<PAGE>

due of any amount so guaranteed or any performance so guaranteed for whatever
reason, the Guarantors shall be jointly and severally obligated to pay the same
immediately. Each Guarantor agrees that this is a guarantee of payment and not
a guarantee of collection.

                  The Guarantors hereby agree that their obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect
to any provisions hereof or thereof, the recovery of any judgment against the
Company, any action to enforce the same or any other circumstance which might
otherwise constitute a legal or equitable discharge or defense of a Guarantor.
Subject to Section 6.06 hereof, each Guarantor hereby waives diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Company, any right to require a proceeding
first against the Company, protest, notice and all demands whatsoever and
covenants that (except as otherwise provided in this Article Eleven) this
Subsidiary Guarantee shall not be discharged except by complete performance of
the obligations contained in the Notes and this Indenture.

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

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

Section 11.02     Subordination of Subsidiary Guarantee.

                  The Obligations of each Guarantor under its Subsidiary
Guarantee pursuant to this Article Eleven shall be subordinated to the prior
payment in full, in cash, of all Indebtedness under the Credit Agreement and
all other Senior Debt of such Guarantor to the same extent the Notes are
subordinated to Senior Debt of the Company. For the purposes of the foregoing
sentence, the Trustee and the Holders shall have the right to receive and/or
retain payments by any of the Guarantors only at such times as they may receive
and/or retain payments in respect of the Notes pursuant to this Indenture,
including Article Ten hereof.

                                      84
<PAGE>

Section 11.03     Limitation on Guarantor Liability.

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

Section 11.04     Execution and Delivery of Subsidiary Guarantee.

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

                  Each Guarantor hereby agrees that its Subsidiary Guarantee
set forth in Section 11.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Note a notation of such
Subsidiary Guarantee.

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

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

                  In the event that the Company creates or acquires any new
Domestic Subsidiaries subsequent to the date of this Indenture, if required by
Section 4.21 hereof, the Company shall cause such Domestic Subsidiaries to
execute supplemental indentures to this Indenture and Subsidiary Guarantees in
accordance with Section 4.21 hereof and this Article Eleven, to the extent
applicable.

Section 11.05     Guarantors May Consolidate, Etc., on Certain Terms.

                  Except as otherwise provided in Section 11.06, a Guarantor
may not sell or otherwise dispose of all or substantially all of its assets, or
consolidate with or merge with or into (whether or not such Guarantor is the
surviving Person) another Person unless:

                                      85
<PAGE>

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

                  (b)      either:

                           (i)      the Person acquiring the property in any
                  such sale or disposition or the Person formed by or surviving
                  any such consolidation or merger is a corporation, organized
                  or existing under the laws of the United States, any state
                  thereof or the District of Columbia and assumes all the
                  obligations of that Guarantor under this Indenture, its
                  Subsidiary Guarantee and the Registration Rights Agreement
                  pursuant to a supplemental indenture satisfactory to the
                  Trustee; or

                           (ii)     such sale or other disposition complies
                  with Section 4.10, including the application of the Net
                  Proceeds therefrom.

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

or in any of the Notes shall prevent any consolidation or merger of a Guarantor
with or into the Company or another Guarantor, or shall prevent any sale or
conveyance of the property of a Guarantor as an entirety or substantially as an
entirety to the Company or another Guarantor.

Section 11.06     Releases Following Sale of Assets.

                  Any Guarantor will be released and relieved of any
obligations under its Subsidiary Guarantee, (i) 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 Company, if the sale or other disposition of all or substantially all of
the assets of that Guarantor complies with Section 4.10 hereof, including the
application of the Net Proceeds therefrom; (ii) 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
Company, if the sale of all such Capital Stock of that Guarantor complies with
Section 4.10 hereof, including the application of the Net Proceeds therefrom;

any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary; or
(iv) 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 Company, if
the sale of such Capital Stock of that Guarantor complies with Section 4.10,
including the application of the Net Proceeds therefrom. Upon delivery by the
Company to the Trustee of an Officers' Certificate and an Opinion of Counsel to
the effect that such sale or other disposition was made by the Company in
accordance with the provisions of this Indenture, including without limitation
Section 4.10 hereof, the Trustee shall execute any documents reasonably
required in order to evidence the release of any Guarantor from its obligations
under its Subsidiary Guarantee.

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

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

                  (ii)     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

         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust solely for the benefit of the Holders, cash in
         U.S. dollars, non-callable Government Securities, or a combination
         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, accrued interest and Liquidated
         Damages, if any, to the date of maturity or redemption;

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

         to the Trustee under this Indenture to apply the deposited money
         toward the payment of the Notes at maturity or the redemption date, as
         the case may be.

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

                  Notwithstanding the above, the Trustee shall pay to the
Company from time to time upon its request any cash or Government Securities
held by it as provided in this section which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written
certification delivered to the Trustee, are in excess of the amount thereof
that would then be required to be deposited to effect a satisfaction and
discharge under this Article Thirteen.

Section 12.02     Deposited Money and Government Securities to Be Held in
                  Trust; Other Miscellaneous Provisions.

accordance with the provisions of such Notes and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal,
premium and Liquidated Damages, if any, and interest, but such money need not
be segregated from other funds except to the extent required by law.

Section 12.03     Repayment to the Company.

then held by the Company, in trust for the payment of the principal of, premium

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

                  The parties may sign any number of copies of this Indenture.

Section 13.15     Acts of Holders.

                  (a)      Any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by the Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Trustee and, where it is hereby expressly required, to the
Company. Such instrument or

                                       92
<PAGE>

instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "ACT" of the Holders signing such instrument or
instruments. Proof of execution of any such instrument or of a writing
appointing any such agent shall be sufficient for any purpose of this Indenture
and conclusive in favor of the Trustee and the Company if made in the manner
provided in this Section 13.14.

                  (b)      The fact and date of the execution by any Person of
any such instrument or writing may be proved by the affidavit of a witness of
such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the
individual signing such instrument or writing acknowledged to such witness,
notary or officer the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of authority. The fact and date
of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which the
Trustee deems sufficient.

                  (c)      Notwithstanding anything to the contrary contained in
this Section 13.14, the principal amount and serial numbers of Notes held by any
Holder, and the date of holding the same, shall be proved by the register of the
Notes maintained by the Registrar as provided in Section 2.04 hereof.

                  (d)      If the Company shall solicit from the Holders of the
Notes any request, demand, authorization, direction, notice, consent, waiver or
other Act, the Company may, at its option, by or pursuant to a resolution of its
Board of Directors, fix in advance a record date for the determination of
Holders entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA ss. 316(c), such record date shall be the record date
specified in or pursuant to such resolution, which shall be a date not earlier
than the date 30 days prior to the first solicitation of Holders generally in
connection therewith or the date of the most recent list of Holders forwarded to
the Trustee prior to such solicitation pursuant to Section 2.06 hereof and not
later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of the then outstanding Notes have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the then outstanding Notes shall be computed as
of such record date; provided that no such authorization, agreement or consent
by the Holders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
eleven months after the record date.

                  (e)      Any request, demand, authorization, direction,
notice, consent, waiver or other Act of the Holder of any Note shall bind every
future Holder of the same Note and the Holder of every Note issued upon the
registration or transfer thereof or in exchange therefor or in lieu thereof in
respect of anything done, omitted or suffered to be done by the Trustee or the
Company in reliance thereon, whether or not notation of such action is made upon
such Note.

<PAGE>

                  (f)      Without limiting the foregoing, a Holder entitled
hereunder to take any action hereunder with regard to any particular Note may do
so itself with regard to all or any part of the principal amount of such Note or
by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such principal amount.

Section 13.16     Benefit of Indenture.

implied, shall give to any Person, other than the parties hereto, any Paying
Agent, any Registrar and its successors hereunder, and the Holders, any benefit
or any legal or equitable right, remedy or claim under this Indenture.

                     11% Senior Subordinated Notes due 2010

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

                  1.       Note.  This Note shall represent the aggregate
principal amount of outstanding Notes from time to time endorsed hereon. The
aggregate principal amount of outstanding Notes represented hereby may from time
to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of this Note to reflect the amount of any increase
or decrease in the aggregate principal amount of outstanding Notes represented
hereby shall be made by the Trustee in accordance with instructions given by the
Holder hereof as required by Section 2.07 of the Indenture.

                  2.       Interest.  The Company promises to pay interest on
the principal amount of this Note at 11% per annum from the date hereof until
maturity and shall pay the Liquidated Damages, if any, payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Company
shall pay interest and Liquidated Damages, if any, semi-annually in arrears on
April 1 and October 1 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each an "Interest Payment Date"). Interest on
the Notes shall accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the date of original issuance; provided
that if there is no existing Default in the payment of interest, and if this
Note is authenticated between a record date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided further that the first Interest
Payment Date shall be October 1, 2002. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at the rate then in
effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest shall be computed
on the basis of a 360-day year of twelve 30-day months.

                  3.       Method of Payment.  The Company shall pay interest on
the Notes (except defaulted interest) and Liquidated Damages, if any, to the
Persons who are registered Holders of Notes at the close of business on the
March 15 or September 15 next preceding the Interest Payment Date, even if such
Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.13 of the Indenture with respect to
defaulted interest. The Notes shall be payable as to principal, premium and
Liquidated Damages, if any, and interest at the office or agency of the Company
maintained for such purpose in The City of New York, or, at the option of the
Company, payment of interest and Liquidated Damages, if any, may be made by
check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately available
funds shall be required with respect to principal of and interest, premium and

                                      A1-5
<PAGE>

Liquidated Damages, if any, on, all Global Notes and all other Notes the Holders
of which shall have provided wire transfer instructions to the Company or the
Paying Agent. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts.

                  4.       Paying Agent and Registrar.  Initially, First Union
National Bank, the Trustee under the Indenture, shall act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Restricted Subsidiaries may act in any
such capacity.

                  5.       Indenture.   The Company issued the Notes under an
Indenture dated as of March 28, 2002 ("Indenture") among the Company, the
Guarantors 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. The Notes are subject to all such terms, and
Holders are referred to the Indenture and such Act for a statement of such
terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. This Note is an obligation of the Company limited to $175.00
million in aggregate principal amount. The Indenture pursuant to which this Note
is issued provides for the issuance of Notes with a maximum aggregate principal
amount of $300.00 million.

                  6.       Optional Redemption.  (a) Except as set forth in
paragraphs 5(b) and 7 below, the Company shall not have the option to redeem the
Notes prior to April 1, 2006. Thereafter, the Company shall have the option to
redeem the Notes, in whole or in part, upon not less than 30 nor more than 60
days' prior notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on April 1 of the years
indicated below (subject to the right of Holder on the relevant record date to
receive interest due on the related Interest Payment Date):

         <S>                                                                          <C>

         2007..................................................................        103.667%
         2008..................................................................        101.833%
         2009 and thereafter...................................................        100.000%
</TABLE>

                  (b)      Notwithstanding the foregoing, at any time prior to
April 1, 2005, the Company may redeem up to 35% of the aggregate principal
amount of Notes issued under the Indenture at a redemption price of 111.000% of
the principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages thereon, if any, to the redemption date, with the net cash proceeds of
one or more Equity Issuances; provided that at least 65% of the aggregate
principal amount of Notes issued under the Indenture remains outstanding
immediately after the occurrence of such redemption (excluding Notes held by the
Company and its Subsidiaries); and such redemption shall occur within 60 days of
the date of the closing of such Equity Issuance.

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

                                      A1-6
<PAGE>

                  8.       Selection and Notice of Redemption.  If less than all
of the Notes are to be redeemed at any time, the Trustee will select Notes for
redemption as follows: (i) if the Notes are listed, in compliance with the
requirements of the principal national securities exchange on which the Notes
are listed, or (ii) if the Notes are not so listed, on a pro rata basis, by lot
or by any method as the Trustee deems fair and appropriate. No Notes of $1,000
or less may be redeemed in part. Except as otherwise provided in the Indenture,
notices of redemption will be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder to be redeemed at
its registered address. Notices of redemption may not be conditional. If any
Note is to be redeemed in part only, the notice of redemption that relates to
that Note will 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. Notes called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest and Liquidated Damages,
if any, cease to accrue on Notes or portions of them called for redemption.

                  9.       Repurchase at Option of Holder.  (a) If there is a
Change of Control, each Holder of Note will have the right to require the
Company to make an offer (a "Change of Control Offer") to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest and Liquidated Damages, if any, to
the date of purchase (the "Change of Control Payment"). Within 10 days following
any Change of Control, the Company shall mail a notice to each Holder describing
the transaction or transactions that constitute the Change of Control and
offering to repurchase Notes on the date specified in such notice, which date
shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed, pursuant to the procedures required by the Indenture and
described in such notice.

                  (b)      When the aggregate amount of Excess Proceeds from one
or more Asset Sales exceeds $5.0 million, the Company shall commence an offer
("Asset Sale Offer") pursuant to Section 4.10 of the Indenture 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 the 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 equal to 100% of principal amount plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase, and shall be
payable in cash, in accordance with the procedures set forth in the Indenture.
If any Excess Proceeds remain after consummation of an Asset Sale Offer, the
company or the Restricted Subsidiary may use such Excess Proceeds for any
purpose not otherwise prohibited by the Indenture. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds will be reset at zero.

                  10.      Denominations, Transfer, Exchange.  The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company is not required
to transfer

                                      A1-7
<PAGE>

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

                  11.      Persons Deemed Owners.  The registered Holder of a
Note will be treated as its owner for all purposes.

                  12.      Amendment, Supplement and Waiver.  Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, the
Notes), and any existing Default or Event of Default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal of the then outstanding Notes (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, the Notes). Without the consent of any
Holder of a Note, the Indenture or the Notes may be amended or supplemented to
cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes
in addition to or in place of Definitive Notes, to provide for the assumption of
the Company's or any Guarantor's obligations to Holders of the Notes in case of
a merger or consolidation or sale of all or substantially all of the assets of
the Company or any Guarantor, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder or to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act.

                  13.      Defaults and Remedies.  In the case of an Event of
Default, as defined in the Indenture arising from certain events of bankruptcy
or insolvency with respect to the Company or any of its Significant
Subsidiaries, all outstanding Notes will become due and payable immediately and
automatically without further action or notice. If any other Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare all the Notes to be
due and payable immediately. 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 principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest or Liquidated Damages, if any) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may, on
behalf of the Holders of all of the Notes, waive any existing Default or Event
of Default and its consequences under the Indenture except a continuing Default
or Event of Default in the payment of interest or Liquidated Damages, if any,
on, or the principal of, the Notes.

                  In the case of any Event of Default occurring by reason of any
willful action or inaction taken or not taken by the Company or on their behalf
with the intention of avoiding payment of the premium that the Company would
have had to pay if it then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs during any
time that the Notes

                                      A1-8
<PAGE>

or Guarantees are outstanding, by reason of any willful action (or inaction)
taken (or not taken) by the Company or on its behalf with the intention of
avoiding the prohibition on redemption of the Notes, then the premium specified
in the Indenture shall also become immediately due and payable to the extent
permitted by law upon the acceleration of the Notes.

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

                  15.      No Recourse Against Others.  No past, present, or
future director, officer, employee, incorporator agent, or stockholder or holder
of any Equity Interest ofthe Company or any of its Subsidiaries, as such, will
have any liability for any of the Company's or any Guarantors' obligations under
the Notes, the Indenture, any Subsidiary Guarantees, the Exchange Notes, the
Registration Rights Agreement or for any claim based on, in respect of, or by
reason of, these obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

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

                  17.      Additional Rights of Holders of Restricted Global
Notes and Restricted Definitive Notes.  In addition to the rights provided to
Holders under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of March 28, 2002, between the Company, the Guarantors and
the parties named on the signature pages thereof or, in the case of Additional
Notes, Holders of Restricted Global Notes and Restricted Definitive Notes shall
have the rights set forth in one or more registration rights agreements, if any,
between the Company, the Guarantors and the other parties thereto, relating to
rights given by the Company and the Guarantors to the purchasers of Additional
Notes (the "Registration Rights Agreement").

                  18.      CUSIP Numbers.  Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP numbers to be printed on the Notes and the Trustee may
use CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Notes or as contained in any notice of redemption and reliance may be placed
only on the other identification numbers placed thereon.

                  The Company shall furnish to any Holder upon written request
and without charge a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:

                     11% Senior Subordinated Notes due 2010

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

                  1.       Note.  This Note shall represent the aggregate
principal amount of outstanding Notes from time to time endorsed hereon. The
aggregate principal amount of outstanding Notes represented hereby may from time
to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of this Note to reflect the amount of any increase
or decrease in the aggregate principal amount of outstanding Notes represented
hereby shall be made by the Trustee in accordance with instructions given by the
Holder hereof as required by Section 2.07 of the Indenture.

                  2.       Interest.  The Company promises to pay interest on
the principal amount of this Note at 11% per annum from the date hereof until
maturity and shall pay the Liquidated Damages, if any, payable pursuant to
Section 5 of the Registration Rights Agreement referred to below. The Company
shall pay interest and Liquidated Damages, if any, semi-annually in arrears on
April 1 and October 1 of each year, or if any such day is not a Business Day, on
the next succeeding Business Day (each an "Interest Payment Date"). Interest on
the Notes shall accrue from the most recent date to which interest has been paid
or, if no interest has been paid, from the date of original issuance; provided
that if there is no existing Default in the payment of interest, and if this
Note is authenticated between a record date referred to on the face hereof and
the next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; provided further that the first Interest
Payment Date shall be October 1, 2002. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
principal and premium, if any, from time to time on demand at the rate then in
effect; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and
Liquidated Damages (without regard to any applicable grace periods) from time to
time on demand at the same rate to the extent lawful. Interest shall be computed
on the basis of a 360-day year of twelve 30-day months.

                  3.       Method of Payment.  The Company shall pay interest
on the Notes (except defaulted interest) and Liquidated Damages, if any, to the
Persons who are registered Holders of Notes at the close of business on the
March 15 or September 15 next preceding the Interest Payment Date, even if such
Notes are canceled after such record date and on or before such Interest Payment
Date, except as provided in Section 2.13 of the Indenture with respect to
defaulted interest. The Notes shall be payable as to principal, premium and
Liquidated Damages, if any, and interest at the office or agency of the Company
maintained for such purpose in The City of New York, or, at the option of the
Company, payment of interest and Liquidated Damages, if any, may be made by
check mailed to the Holders at their addresses set forth in the register of
Holders, and provided that payment by wire transfer of immediately

                                      A2-5
<PAGE>

available funds shall be required with respect to principal of and interest,
premium and Liquidated Damages, if any, on, all Global Notes and all other Notes
the Holders of which shall have provided wire transfer instructions to the
Company or the Paying Agent. Such payment shall be in such coin or currency of
the United States of America as at the time of payment is legal tender for
payment of public and private debts.

                  4.       Paying Agent and Registrar.  Initially, First Union
National Bank, the Trustee under the Indenture, shall act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Restricted Subsidiaries may act in any
such capacity.

                  5.       Indenture.  The Company issued the Notes under an
Indenture dated as of March 28, 2002 ("Indenture") among the Company, the
Guarantors. 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. The Notes are subject to all such terms, and Holders are
referred to the Indenture and such Act for a statement of such terms. To the
extent any provision of this Note conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling. This
Note is an obligation of the Company limited to $175.00 in aggregate principal
amount. The Indenture pursuant to which this Note is issued provides for the
issuance of Notes with a maximum aggregate principal amount of $300.00 million.

                  6.       Optional Redemption.  (a) Except as set forth in
paragraphs 5(b) and 7 below, the Company shall not have the option to redeem the
Notes prior to April 1, 2006. Thereafter, the Company shall have the option to
redeem the Notes, in whole or in part, upon not less than 30 nor more than 60
days' prior notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the applicable redemption date, if
redeemed during the twelve-month period beginning on April 1 of the years
indicated below (subject to the right of Holder on the relevant record date to
receive interest due on the related Interest Payment Date):

         ----                                                                         ----------
         <S>                                                                          <C>

         2009 and thereafter...................................................        100.000%
</TABLE>

                  (b)      Notwithstanding the foregoing, at any time prior to
April 1, 2005, the Company may redeem up to 35% of the aggregate principal
amount of Notes issued under the Indenture at a redemption price of 111.000% of
the principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages thereon, if any, to the redemption date, with the net cash proceeds of
one or more Equity Issuances; provided that at least 65% of the aggregate
principal amount of Notes issued under the Indenture remains outstanding
immediately after the occurrence of such redemption (excluding Notes held by the
Company and its Subsidiaries); and such redemption shall occur within 60 days of
the date of the closing of such Equity Issuance.

<PAGE>

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

                  8.       Selection and Notice of Redemption.  If less than
all of the Notes are to be redeemed at any time, the Trustee will select Notes
for redemption as follows: (i) if the Notes are listed, in compliance with the
requirements of the principal national securities exchange on which the Notes
are listed, or (ii) if the Notes are not so listed, on a pro rata basis, by lot
or by any method as the Trustee deems fair and appropriate. No Notes of $1,000
or less may be redeemed in part. Except as otherwise provided in the Indenture,
notices of redemption will be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each Holder to be redeemed at
its registered address. Notices of redemption may not be conditional. If any
Note is to be redeemed in part only, the notice of redemption that relates to
that Note will 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. Notes called for redemption become due on the date fixed for
redemption. On and after the redemption date, interest and Liquidated Damages,
if any, cease to accrue on Notes or portions of them called for redemption.

                  9.       Repurchase at Option of Holder.  (a) If there is a
Change of Control, each Holder of Note will have the right to require the
Company to make an offer (a "Change of Control Offer") to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 101% of the aggregate principal amount of Notes
repurchased plus accrued and unpaid interest and Liquidated Damages, if any, to
the date of purchase (the "Change of Control Payment"). Within 10 days following
any Change of Control, the Company shall mail a notice to each Holder describing
the transaction or transactions that constitute the Change of Control and
offering to repurchase Notes on the date specified in such notice, which date
shall be no earlier than 30 days and no later than 60 days from the date such
notice is mailed, pursuant to the procedures required by the Indenture and
described in such notice.

                  (b)      When the aggregate amount of Excess Proceeds from one
or more Asset Sales exceeds $5.0 million, the Company shall commence an offer
("Asset Sale Offer") pursuant to Section 4.10 of the Indenture 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 the 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 equal to 100% of principal amount plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase, and shall be
payable in cash, in accordance with the procedures set forth in the Indenture.
If any Excess Proceeds remain after consummation of an Asset Sale Offer, the
Company or the Restricted Subsidiary may use such Excess Proceeds for any
purpose not otherwise prohibited by the Indenture. Upon completion of each Asset
Sale Offer, the amount of Excess Proceeds will be reset at zero.

                  10.      Denominations, Transfer, Exchange.  The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The

                                      A2-7
<PAGE>

Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
The Company is not required to transfer or exchange any Note selected for
redemption. Also, the Company is not required to transfer or exchange any Note
for a period of 15 days before a selection of Notes to be redeemed.

                  11.      Persons Deemed Owners.  The registered Holder of a
Note will be treated as its owner for all purposes.

                  12.      Amendment, Supplement and Waiver.  Subject to
certain exceptions, the Indenture or the Notes may be amended or supplemented
with the consent of the Holders of at least a majority in principal amount of
the then outstanding Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, the
Notes), and any existing Default or Event of Default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal of the then outstanding Notes (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, the Notes). Without the consent of any
Holder of a Note, the Indenture or the Notes may be amended or supplemented to
cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes
in addition to or in place of Definitive Notes, to provide for the assumption of
the Company's or any Guarantor's obligations to Holders of the Notes in case of
a merger or consolidation or sale of all or substantially all of the assets of
the Company or any Guarantor, to make any change that would provide any
additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with the requirements of the SEC in order to effect or maintain the
qualification of the Indenture under the Trust Indenture Act.

                  13.      Defaults and Remedies.  In the case of an Event of
Default, as defined in the Indenture arising from certain events of bankruptcy
or insolvency with respect to the Company or any of its Significant
Subsidiaries, all outstanding Notes will become due and payable immediately and
automatically without further action or notice. If any other Event of Default
occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare all the Notes to be
due and payable immediately. 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 principal amount of the then outstanding
Notes may direct the Trustee in its exercise of any trust or power. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest or Liquidated Damages, if any) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may, on
behalf of the Holders of all of the Notes, waive any existing Default or Event
of Default and its consequences under the Indenture except a continuing Default
or Event of Default in the payment of interest or Liquidated Damages, if any,
on, or the principal of, the Notes.

                  In the case of any Event of Default occurring by reason of any
willful action or inaction taken or not taken by the Company or on their behalf
with the intention of avoiding payment of the premium that the Company would
have had to pay if it then had elected to

                                      A2-8
<PAGE>

redeem the Notes pursuant to the optional redemption provisions of the
Indenture, an equivalent premium shall also become and be immediately due and
payable to the extent permitted by law upon the acceleration of the Notes. If an
Event of Default occurs during any time that the Notes or Guarantees are
outstanding, by reason of any willful action (or inaction) taken (or not taken)
by the Company or on its behalf with the intention of avoiding the prohibition
on redemption of the Notes, then the premium specified in the Indenture shall
also become immediately due and payable to the extent permitted by law upon the
acceleration of the Notes.

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

                  15.      No Recourse Against Others.  No past, present or
future director, officer, employee, incorporator, agent, stockholder or holder
of any Equity Interest of the Company or any of its Subsidiaries, as such, will
have any liability for any of the Company's or any Guarantors' obligations under
the Notes, the Indenture, any Subsidiary Guarantees, the Exchange Notes, the
Registration Rights Agreement or for any claim based on, in respect of, or by
reason of, these obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

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

                  17.      Additional Rights of Holders of Restricted Global
Notes and Restricted Definitive Notes. In addition to the rights provided to
Holders under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Registration Rights
Agreement dated as of March 28, 2002, between the Company, the Guarantors and
the parties named on the signature pages thereof or, in the case of Additional
Notes, Holders of Restricted Global Notes and Restricted Definitive Notes shall
have the rights set forth in one or more registration rights agreements, if any,
between the Company, the Guarantors and the other parties thereto, relating to
rights given by the Company and the Guarantors to the purchasers of Additional
Notes (the "Registration Rights Agreement").

                  18.      CUSIP Numbers.  Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP numbers to be printed on the Notes and the Trustee may
use CUSIP numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on
the Notes or as contained in any notice of redemption and reliance may be placed
only on the other identification numbers placed thereon.

                  The Company shall furnish to any Holder upon written request
and without charge a copy of the Indenture and/or the Registration Rights
Agreement. Requests may be made to:

                  1.       Check if Transferee will take delivery of a

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

                  (b) either:

                           (i)      the Person acquiring the property in any
                  such sale or disposition or the Person formed by or surviving
                  any such consolidation or merger is a corporation, organized
                  or existing under the laws of the United States, any state
                  thereof or the District of Columbia and assumes all the
                  obligations of that Guarantor under this Indenture, its
                  Subsidiary Guarantee and the Registration Rights Agreement
                  pursuant to a supplemental indenture satisfactory to the
                  Trustee; or

                           (ii)     such sale or other disposition complies with
                  Section 4.10, including the application of the Net Proceeds
                  therefrom.

                  In case of any such consolidation, merger, sale or conveyance

executed and delivered to the Trustee and satisfactory in form to the Trustee,
of the Subsidiary Guarantee endorsed upon the Notes and the due and punctual
performance of all of the covenants and conditions of the Indenture to be
performed by 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.

<PAGE>

Such successor Person thereupon may cause to be signed any or all of the
Subsidiary Guarantees to be endorsed upon all of the Notes issuable hereunder
which theretofore shall not have been signed by the Company and delivered to the
Trustee. All the Subsidiary Guarantees so issued shall in all respects have the
same legal rank and benefit under the Indenture as the Subsidiary Guarantees
theretofore and thereafter issued in accordance with the terms of the Indenture
as though all of such Subsidiary Guarantees had been issued at the date of the
execution hereof.

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

                  6.       Releases.

                  (a) Any Guarantor will be released and relieved of any
         obligations under its Subsidiary Guarantee, (i) 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 Company, if the sale or
         other disposition of all or substantially all of the assets of that
         Guarantor complies with Section 4.10 of the Indenture, including the
         application of the Net Proceeds therefrom; (ii) 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 Company, if the sale of all such Capital Stock of
         that Guarantor complies with Section 4.10 of the Indenture, including
         the application of the Net Proceeds therefrom; (iii) if the Company
         designates any Restricted Subsidiary that is a Guarantor as an
         Unrestricted Subsidiary in accordance with the terms hereof; or (iv) 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
         Company, if the sale of such Capital Stock of that Guarantor complies
         with Section 4.10, including the application of the Net Proceeds
         therefrom. Upon delivery by the Company to the Trustee of an Officers'
         Certificate and an Opinion of Counsel to the effect that such sale or
         other disposition was made by the Company in accordance with the
         provisions of the Indenture, including without limitation Section 4.10
         hereof, the Trustee shall execute any documents reasonably required in
         order to evidence the release of any Guarantor from its obligations
         under its Subsidiary Guarantee.

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

                  7.       No Recourse Against Others. No past, present or
future director, officer, employee, incorporator, stockholder or agent of the
Guaranteeing Subsidiary, as such, shall have any liability for any obligations
of the Company or any Guaranteeing Subsidiary under the Notes, any Subsidiary
Guarantees, the Indenture or this Supplemental Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each
Holder of the

<PAGE>

Notes by accepting a Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Notes. Such waiver may
not be effective to waive liabilities under the federal securities laws.

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

                  9.       Counterparts. The parties may sign any number of

Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guaranteeing Subsidiary and the

benefits of this Agreement are the Transfer Restricted Securities.

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

SECTION 3. REGISTERED EXCHANGE OFFER

         (a)      Unless the Exchange Offer shall not be permissible under
applicable law or Commission policy (after the procedures set forth in Section
6(a) below have been complied with), the Company and the Guarantors shall (i)
cause to be filed with the Commission as soon as practicable after the Closing
Date, but in no event later than 60 days after the Closing Date, a Registration
Statement under the Securities Act relating to the Exchange Notes and the
Exchange Offer, (ii) use their best efforts to cause such Registration Statement
to become effective at the earliest possible time, but in no event later than
150 days after the Closing Date, (iii) in connection with the foregoing, file
(A) all pre-effective amendments to such Registration Statement as may be
necessary in order to cause such Registration Statement to become effective, (B)
if applicable, a post-effective amendment to such Registration Statement
pursuant to Rule 430A under the Securities Act and (C) cause all necessary
filings in connection with the registration and qualification of the Exchange
Notes to be made under the Blue Sky laws of such jurisdictions as are necessary
to permit Consummation of the Exchange Offer, and (iv) upon the effectiveness of
such Registration Statement, commence and consummate the Exchange Offer. The
Exchange Offer shall be on the appropriate form permitting registration of the
Exchange Notes to be offered in exchange for the Transfer Restricted Securities
and to permit resales of Notes held by Broker-Dealers as contemplated by Section
3(c) below.

         (b)      The Company shall cause the Exchange Offer Registration
Statement to be effective continuously and shall keep the Exchange Offer open
for a period of not less than the minimum period required under applicable
federal and state securities laws; provided, however, that in no event shall
such period be less than 30 days after the Effectiveness Target Date. The
Company shall cause the Exchange Offer to comply in all material respects with
all applicable federal and state securities laws. No securities other than the
Notes shall be included in the Exchange Offer Registration Statement. The
Company shall use its best efforts to cause the Exchange Offer to be Consummated
on the earliest practicable date after the Exchange Offer Registration Statement
has become effective, but in no event later than 180 days after the Closing
Date.

         (c)      The Company shall indicate in a "Plan of Distribution" section
contained in the Prospectus forming a part of the Exchange Offer Registration
Statement that any Broker-Dealer who holds Initial Notes that are Transfer
Restricted Securities and that were acquired for its own account as a result of
market-making

<PAGE>

activities or other trading activities (other than Transfer Restricted
Securities acquired directly from the Company), may exchange such Initial Notes
pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be
an "underwriter" within the meaning of the Securities Act, in which case it must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of the Exchange Notes received by such Broker-Dealer
in the Exchange Offer, which prospectus delivery requirement may be satisfied by
the delivery by such Broker-Dealer of the Prospectus contained in the Exchange
Offer Registration Statement. Such "Plan of Distribution" section shall also
contain all other information with respect to such resales by Broker-Dealers
that the Commission may require in order to permit such resales pursuant
thereto, but such "Plan of Distribution" shall not name any such Broker-Dealer
or disclose the amount of Notes held by any such Broker-Dealer except to the
extent required by the Commission as a result of a change in policy after the
date of this Agreement.

                  The Company and the Guarantors shall use their best efforts to
keep the Exchange Offer Registration Statement continuously effective,
supplemented and amended as required by the provisions of Section 6(c) below to
the extent necessary to ensure that it is available for resales of Notes
acquired by Broker-Dealers for their own accounts as a result of market-making
activities or other trading activities, and to ensure that it conforms with the
requirements of this Agreement, the Securities Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period
ending on the earlier of (i) 60 days from the date on which the Exchange Offer
Registration Statement is declared effective and (ii) the date on which a
Broker-Dealer is no longer required to deliver a prospectus in connection with
market-making or other trading activities.

                  The Company shall provide sufficient copies of the latest
version of such Prospectus to Broker-Dealers promptly upon request at any time
during such 180-day (or shorter as provided in the foregoing sentence) period in
order to facilitate such resales.

SECTION 4. SHELF REGISTRATION

         (a)      Shelf Registration. If (i) the Company and the Guarantors are
not required to file an Exchange Offer Registration Statement or to consummate
the Exchange Offer because the Exchange Offer is not permitted by applicable law
or Commission policy (after the procedures set forth in Section 6(a) below have
been complied with) or (ii) if any Holder of Transfer Restricted Securities
notifies the Company in writing prior to the 20th day following the consummation
of the Exchange Offer that (A) such Holder is prohibited by law or Commission
policy from participating in the Exchange Offer, or (B) such Holder may not
resell the Exchange Notes acquired by it in the Exchange Offer to the public
without delivering a prospectus and that the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Notes
acquired directly from the Company or one of its affiliates, then, upon such
Holder's request, the Company and the Guarantors shall

                  (x) cause to be filed a shelf registration statement
         pursuant to Rule 415 under the Securities Act, which may be
         an amendment to the Exchange Offer Registration Statement (in
         either event, the "Shelf Registration Statement") on or prior
         to the earliest to occur of (1) the 60th day after the date
         on which the Company determines that it is not required to
         file the Exchange Offer Registration Statement pursuant to
         clause (i) above, and (2) the 60th day after the date on
         which the Company receives notice from a Holder of Transfer
         Restricted Securities as contemplated by clause (ii) above,
         (such earliest date being the "Shelf Filing Deadline"), which
         Shelf Registration Statement shall provide for resales of all
         Transfer Restricted Securities the Holders of which shall
         have provided the information required pursuant to Section
         4(b) hereof; and

                  (y) use their best efforts to cause such Shelf
         Registration Statement to be declared effective by the
         Commission on or before the 150th day after the date on which
         the obligation to file the Shelf Registration Statement
         arose.

<PAGE>

The Company and the Guarantors shall use their best efforts to keep such Shelf
Registration Statement continuously effective, supplemented and amended as
required by the provisions of Sections 6(b) and (c) hereof to the extent
necessary to ensure that it is available for resales of Notes by the Holders of
Transfer Restricted Securities entitled to the benefit of this Section 4(a), and
to ensure that it conforms with the requirements of this Agreement, the
Securities Act and the policies, rules and regulations of the Commission as
announced from time to time, for a period of at least one year following the
effective date of such Shelf Registration Statement (or shorter period that will
terminate when all the Notes covered by such Shelf Registration Statement have
been sold pursuant to such Shelf Registration Statement).

         (b)      Provision by Holders of Certain Information in Connection with
the Shelf Registration Statement. No Holder of Transfer Restricted Securities
may include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 business days after receipt of a request
therefor, such information as the Company may reasonably request for use in
connection with any Shelf Registration Statement or Prospectus or preliminary
Prospectus included therein. Each Holder as to which any Shelf Registration
Statement is being effected agrees to furnish promptly to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Holder not materially misleading.

SECTION 5. LIQUIDATED DAMAGES

                  If (i) any of the Registration Statements required by this
Agreement is not filed with the Commission on or prior to the date specified for
such filing in this Agreement, (ii) any of such Registration Statements has not
been declared effective by the Commission on or prior to the date specified for
such effectiveness in this Agreement (the "Effectiveness Target Date"), (iii)
the Exchange Offer has not been Consummated within 30 business days after the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement or (iv) any Registration Statement required by this Agreement is filed
and declared effective but shall thereafter cease to be effective or fail to be
usable for its intended purpose without being succeeded within 3 Business Days
by a post-effective amendment to such Registration Statement that cures such
failure and that is itself promptly declared effective (each such event referred
to in clauses (i) through (iv), a "Registration Default"), the Company and the
Guarantors hereby jointly and severally agree to pay to each Holder of Transfer
Restricted Securities affected thereby liquidated damages ("Liquidated Damages")
in an amount equal to $.05 per week per $1,000 in principal amount of Transfer
Restricted Securities held by such Holder for each week or portion thereof that
the Registration Default continues for the first 90-day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $.05 per week per $1,000 in
principal amount of Transfer Restricted Securities with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum amount of Liquidated Damages of $.50 per week per $1,000 in principal
amount of Transfer Restricted Securities. Following the cure of all Registration
Defaults relating to any particular Transfer Restricted Securities, the
Liquidated Damages payable with respect to the Transfer Restricted Securities as
a result of the provisions of this paragraph shall cease.

                  All obligations of the Company and the Guarantors set forth in
the preceding paragraph that are outstanding with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted
Security shall survive until such time as all such obligations with respect to
such Note shall have been satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

         (a)      Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company and the Guarantors shall comply with all of the
provisions of Section 6(c) below, shall use their best efforts to effect such
exchange to permit the sale of Transfer Restricted Securities being sold in
accordance with the intended method or methods of distribution thereof, and
shall comply with all of the following provisions:

<PAGE>

                  (i)      If in the reasonable opinion of counsel to the
Company there is a question as to whether the Exchange Offer is permitted by
applicable law, the Company and the Guarantors hereby agree to seek a no-action
letter or other favorable decision from the Commission allowing the Company and
the Guarantors to Consummate an Exchange Offer for such Initial Notes. The
Company and the Guarantors each hereby agrees to pursue the issuance of such a
decision to the Commission staff level but shall not be required to take
commercially unreasonable action to effect a change of Commission policy. The
Company and the Guarantors each hereby agrees, however, to (A) participate in

an analysis prepared by counsel to the Company setting forth the legal bases, if
any, upon which such counsel has concluded that such an Exchange Offer should be
permitted and (C) diligently pursue a favorable resolution by the Commission
staff of such submission.

                  (ii)     As a condition to its participation in the Exchange
Offer pursuant to the terms of this Agreement, each Holder of Transfer
Restricted Securities shall furnish, upon the request of the Company, prior to
the Consummation thereof, a written representation to the Company (which may be
contained in the letter of transmittal contemplated by the Exchange Offer
Registration Statement) to the effect that (A) it is not an affiliate of the
Company (as defined in Rule 144 promulgated under the Securities Act), (B) it is
not engaged in, and does not intend to engage in, and has no arrangement or
understanding with any person to participate in, a distribution of the Exchange
Notes to be issued in the Exchange Offer and (C) it is acquiring the Exchange
Notes in its ordinary course of business. In addition, all such Holders of
Transfer Restricted Securities shall otherwise cooperate in the Company's
preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees
that any Broker-Dealer and any such Holder using the Exchange Offer to
participate in a distribution of the securities to be acquired in the Exchange
Offer (1) could not under Commission policy as in effect on the date of this
Agreement rely on the position of the Commission enunciated in Morgan Stanley
and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation
(available May 13, 1988), as interpreted in the Commission's letter to Shearman
& Sterling dated July 2, 1993, and similar no-action letters (which may include
any no-action letter obtained pursuant to clause (i) above), and (2) must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with a secondary resale transaction and that such a secondary
resale transaction should be covered by an effective registration statement
containing the selling security holder information required by Item 507 or 508,
as applicable, of Regulation S-K if the resales are of Exchange Notes obtained
by such Holder in exchange for Initial Notes acquired by such Holder directly
from the Company.

         (b)      Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company and the Guarantors shall comply with all the
provisions of Section 6(c) below and shall use their best efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold
in accordance with the intended method or methods of distribution thereof, and
pursuant thereto the Company will as expeditiously as possible prepare and file
with the Commission a Registration Statement relating to the registration on any
appropriate form under the Securities Act, which form shall be available for the
sale of the Transfer Restricted Securities in accordance with the intended
method or methods of distribution thereof.

         (c)      General Provisions. In connection with any Registration
Statement and any Prospectus required by this Agreement to permit the sale or
resale of Transfer Restricted Securities (including, without limitation, any
Registration Statement and the related Prospectus required to permit resales of
Notes by Broker-Dealers), the Company shall:

                  (i)      use its best efforts to keep such Registration
Statement continuously effective and provide all requisite financial statements
(including, if required by the Securities Act or any regulation thereunder,
financial statements of the Guarantors for the period specified in Section 3 or
4 of this Agreement, as applicable; upon the occurrence of any event that would
cause any such Registration Statement or the Prospectus contained therein (A) to
contain a material misstatement or omission or (B) not to be effective and
usable for resale of Transfer Restricted Securities during the period required
by this Agreement, the Company shall file promptly an appropriate amendment to
such Registration Statement, in the case of clause (A), correcting any such
misstatement or omission, and, in the case of either clause (A) or (B), use its
best efforts to

<PAGE>

cause such amendment to be declared effective and such Registration Statement
and the related Prospectus to become usable for their intended purpose(s) as
soon as practicable thereafter;

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

                  (iii)    advise the underwriter(s), if any, and selling
Holders promptly and, if requested by such Persons, to confirm such advice in
writing, (A) when the Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to any Registration Statement or any
post-effective amendment thereto, when the same has become effective, (B) of any
request by the Commission for amendments to the Registration Statement or
amendments or supplements to the Prospectus or for additional information
relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement under the Securities
Act or of the suspension by any state securities commission of the qualification
of the Transfer Restricted Securities for offering or sale in any jurisdiction,
or the initiation of any proceeding for any of the preceding purposes, and (D)
of the existence of any fact or the happening of any event that makes any
statement of a material fact made in the Registration Statement, the Prospectus,
any amendment or supplement thereto, or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the Registration Statement or the Prospectus in order to make such statement not
misleading. If at any time the Commission shall issue any stop order suspending
the effectiveness of the Registration Statement, or any state securities
commission or other regulatory authority shall issue an order suspending the
qualification or exemption from qualification of the Transfer Restricted
Securities under state securities or Blue Sky laws, the Company and the
Guarantors shall use their best efforts to obtain the withdrawal or lifting of
such order at the earliest possible time;

                  (iv)     furnish without charge to each of the Initial
Purchasers, each selling Holder named in any Registration Statement, and each of
the underwriter(s), if any, before filing with the Commission, a copy of any
Registration Statement or any Prospectus included therein or any amendments or
supplements to any such Registration Statement or Prospectus, which documents
will be subject to the review of the Initial Purchasers and underwriter(s) in
connection with such sale, if any, for a period of at least three business days,
and the Company will not file any such Registration Statement or Prospectus or
any amendment or supplement to any such Registration Statement or Prospectus to
which an Initial Purchaser of Transfer Restricted Securities covered by such
Registration Statement or the underwriter(s), if any, shall reasonably object in
writing within three business days after the receipt thereof (such objection to
be deemed timely made upon confirmation of telecopy transmission within such
period). The objection of an Initial Purchaser or underwriter, if any, shall be
deemed to be reasonable if such Registration Statement, amendment, Prospectus or
supplement, as applicable, as proposed to be filed, contains a misstatement of
material fact or there is an omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading;

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

                  (vi)     make available at reasonable times for inspection by
the Initial Purchasers, any managing underwriter participating in any
disposition pursuant to such Registration Statement and any attorney or

financial and other records, pertinent corporate documents and properties of the
Company and the Guarantors and cause the Company's and the Guarantors' officers,
directors and employees to supply all information reasonably requested by any
such Holder, underwriter, attorney or accountant in connection with such
Registration Statement subsequent to the filing thereof and prior to its
effectiveness; provided, however, that the foregoing information gathering (i)
shall be coordinated on behalf of the Initial Purchasers, managing underwriter
or any representative thereof, by one counsel, who shall be Shearman & Sterling,
or such other counsel as may be chosen by the Holders of a majority in principal
amount of Transfer Restricted Securities and (ii) shall not be available for any
such Holder who does not agree in writing to hold such information in
confidence;

                  (vii)    if requested by the Initial Purchasers or the
underwriter(s), if any, promptly incorporate in any Registration Statement or
Prospectus, pursuant to a supplement or post-effective amendment if necessary,
such information required to be included under the Securities Act as such
selling Holders and underwriter(s), if any, may reasonably request to have
included therein, including, without limitation, information relating to the
"Plan of Distribution" of the Transfer Restricted Securities, information with
respect to the principal amount of Transfer Restricted Securities being sold to
such underwriter(s), the purchase price being paid therefor and any other terms
of the offering of the Transfer Restricted Securities to be sold in such
offering; and make all required filings of such Prospectus supplement or
post-effective amendment as soon as practicable after the Company is notified of
the matters to be incorporated in such Prospectus supplement or post-effective
amendment;

                  (viii)   deliver to each selling Holder and each of the
underwriter(s), if any, without charge, as many copies of the Prospectus
(including each preliminary prospectus) and any amendment or supplement thereto
as such Persons reasonably may request to sell the Transfer Restricted
Securities; the Company and the Guarantors hereby consent to the use of the
Prospectus and any amendment or supplement thereto by each of the selling
Holders and each of the underwriter(s), if any, in connection with the offering
and the sale of the Transfer Restricted Securities covered by the Prospectus or
any amendment or supplement thereto;

                  (ix)     enter into, and cause the Guarantors to enter into,
such agreements (including an underwriting agreement), and make, and cause the
Guarantors to make, such representations and warranties, and take all such other
actions in connection therewith in order to expedite or facilitate the
disposition of the Transfer Restricted Securities pursuant to any Registration
Statement contemplated by this Agreement, all to such extent as may be requested
by any Initial Purchaser or by any Holder of $500,000 or more of Transfer
Restricted Securities or underwriter in connection with any sale or resale
pursuant to any Registration Statement contemplated by this Agreement; and
whether or not an underwriting agreement is entered into and whether or not the
registration is an Underwritten Registration, the Company and the Guarantors
shall:

                  (A)      furnish to each Initial Purchaser, on behalf of each
         selling Holder, and each underwriter, if any, in such substance and
         scope as they may reasonably request and as are customarily made by
         issuers to underwriters in primary underwritten offerings, upon the
         date of the Consummation of the Exchange Offer and, if applicable, the
         effectiveness of the Shelf Registration Statement:

                           (1)      a certificate, dated the date of
                  Consummation of the Exchange Offer or the date of
                  effectiveness of the Shelf Registration Statement, as the case
                  may be, signed by (y) the President or any Vice President and
                  (z) a principal financial or accounting officer of each of the
                  Company and the Guarantors, confirming, as of the date
                  thereof, the matters set forth in paragraphs (i), (ii) and
                  (iii) of Section 5(e) of the Purchase Agreement and such other
                  matters as such parties may reasonably request;

<PAGE>

                           (2)      an opinion, dated the date of Consummation
                  of the Exchange Offer or the date of effectiveness of the
                  Shelf Registration Statement, as the case may be, of counsel
                  for the Company and the Guarantors, covering the matters set
                  forth in Section 5(c) of the Purchase Agreement and such other
                  matter as such parties may reasonably request, and in any
                  event including a statement to the effect that such counsel
                  has participated in conferences with officers and other
                  representatives of the Company, representatives of the
                  independent public accountants for the Company, the Initial
                  Purchasers' representatives and the Initial Purchasers'
                  counsel in connection with the preparation of such
                  Registration Statement and the related Prospectus and have
                  considered the matters required to be stated therein and the
                  statements contained therein, although such counsel has not
                  independently verified the accuracy, completeness or fairness
                  of such statements; and that such counsel advises that, on the
                  basis of the foregoing (relying as to materiality upon facts
                  provided to such counsel by officers and other representatives
                  of the Company and without independent check or verification),
                  no facts came to such counsel's attention that caused such
                  counsel to believe that the applicable Registration Statement,
                  at the time such Registration Statement or any post-effective
                  amendment thereto became effective, and, in the case of the
                  Exchange Offer Registration Statement, as of the date of
                  Consummation, contained an untrue statement of a material fact
                  or omitted to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading, or that the Prospectus contained in such
                  Registration Statement as of its date and, in the case of the
                  opinion dated the date of Consummation of the Exchange Offer,
                  as of the date of Consummation, contained an untrue statement
                  of a material fact or omitted to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made, not
                  misleading. Without limiting the foregoing, such counsel may
                  state further that such counsel assumes no responsibility for,
                  and has not independently verified, the accuracy, completeness
                  or fairness of the financial statements, notes and schedules
                  and other financial data included in any Registration
                  Statement contemplated by this Agreement or the related
                  Prospectus; and

                           (3)      a customary comfort letter, dated as of the
                  date of Consummation of the Exchange Offer or the date of
                  effectiveness of the Shelf Registration Statement, as the case
                  may be, from the Company's independent accountants, in the
                  customary form and covering matters of the type customarily
                  covered in comfort letters by underwriters in connection with
                  primary underwritten offerings, and affirming the matters set
                  forth in the comfort letters delivered pursuant to Section
                  5(a) of the Purchase Agreement, without exception;

                  (B)      set forth in full or incorporate by reference in the
         underwriting agreement, if any, the indemnification provisions and
         procedures of Section 8 hereof with respect to all parties to be
         indemnified pursuant to said Section; and

                  (C)      deliver such other documents and certificates as may
         be reasonably requested by such parties to evidence compliance with
         clause (A) above and with any customary conditions contained in the
         underwriting agreement or other agreement entered into by the Company
         or the Guarantors pursuant to this clause (xi), if any.

                  If at any time the representations and warranties of the
Company and the Guarantors contemplated in clause (A)(1) above cease to be true
and correct in any material respect, the Company or the Guarantors shall so
advise the Initial Purchasers and the underwriter(s), if any, promptly and, if
requested by such Persons, shall confirm such advice in writing;

                           (x)      prior to any public offering of Transfer

with, the selling Holders, the underwriter(s), if any, and their respective
counsel in connection with the registration and qualification of the Transfer
Restricted Securities under the securities or Blue Sky laws of such
jurisdictions as the selling Holders or underwriter(s) may request and do

disposition in such jurisdictions of the Transfer Restricted Securities covered
by the Registration Statement; provided, however, that neither the Company nor
the Guarantors shall be required to register or qualify as a foreign corporation
where it is not then so qualified or to take any action that would subject it to
the service of process in suits or to taxation, other than as to matters and
transactions relating to the Registration Statement, in any jurisdiction where
it is not then so subject;

                           (xiv)    if any fact or event contemplated by Section
6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or
post-effective amendment to the Registration Statement or related Prospectus or
any document incorporated therein by reference or file any other required

Restricted Securities, the Prospectus will not contain an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading;

                           (xv)     with respect to the Exchange Offer, provide

pursuant to this paragraph shall be treated as a Registration Default for
purposes of Section 5.

any claim or action, or any investigation or proceeding by any governmental
agency or body, commenced or threatened, including the reasonable fees and
expenses of counsel to any Indemnified Holder), directly or indirectly caused
by, related to, based upon, arising out of or in connection with any untrue
statement or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus (or any amendment or supplement thereto),
or any omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities, judgments, actions
or expenses are caused by an untrue statement or omission or alleged untrue
statement or omission that is made in reliance upon and in conformity with
information relating to any of the Holders furnished in writing to the Company
by any of the Holders expressly for use therein. This indemnity agreement shall
be in addition to any liability which the Company may otherwise have.

                  In case any action or proceeding (including any governmental
or regulatory investigation or proceeding) shall be brought or asserted against
any of the Indemnified Holders with respect to which indemnity may be sought
against the Company or the Guarantors, such Indemnified Holder (or the
Indemnified Holder controlled by such controlling person) shall promptly notify
the Company and the Guarantors in writing (provided, that the failure to give
such notice shall not relieve the Company or the Guarantors of their respective
obligations pursuant to this Agreement). Such Indemnified Holder shall have the
right to employ its own counsel in any such action and the fees and expenses of
such counsel shall be paid, as incurred, by the Company and the Guarantors
(regardless of whether it is ultimately determined that an Indemnified Holder is
not entitled to indemnification hereunder). Neither the Company nor the
Guarantors shall, in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances, be
liable for the reasonable fees and expenses of more than one separate firm of
attorneys (in addition to any local counsel) at any time for such Indemnified
Holders, which firm shall be designated by the Holders. The Company shall be
liable for any settlement of any such action or proceeding effected with the
Company's prior written consent, which consent shall not be withheld
unreasonably, and the Company agrees to indemnify and hold harmless any
Indemnified Holder from and against any loss, claim, damage, liability or
expense by reason of any settlement of any action effected with the written
consent of the Company. The Company shall not, without the prior written consent
of each Indemnified Holder, settle or compromise or consent to the entry of

<PAGE>

judgment in or otherwise seek to terminate any pending or threatened action,
claim, litigation or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not any Indemnified Holder is a
party thereto), unless such settlement, compromise, consent or termination
includes an unconditional release of each Indemnified Holder from all liability
arising out of such action, claim, litigation or proceeding.

         (b)      Each Holder of Transfer Restricted Securities agrees,
severally and not jointly, to indemnify and hold harmless the Company and the
Guarantors and their respective directors, officers of the Company who sign a
Registration Statement, and any person controlling (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company,
and the respective officers, directors, partners, employees, representatives and
agents of each such person, to the same extent as the foregoing indemnity from
the Company and the Guarantors to each of the Indemnified Holders, but only with
respect to claims and actions based on information relating to such Holder
furnished in writing to the Company by such Holder expressly for use in any
Registration Statement. In case any action or proceeding shall be brought
against the Company or its directors or officers or any such controlling person
in respect of which indemnity may be sought against a Holder of Transfer
Restricted Securities, such Holder shall have the rights and duties given the
Company and the Company or its directors or officers or such controlling person
shall have the rights and duties given to each Holder by Section 8(a). In no
event shall the liability of any selling Holder hereunder be greater in amount
than the dollar amount of the proceeds received by such Holder upon the sale of
the Securities giving rise to such indemnification obligation.

         (c)      If the indemnification provided for in this Section 8 is
unavailable to an indemnified party under Section 8(a) or Section 8(b) hereof
(other than by reason of exceptions provided in those Sections) in respect of
any losses, claims, damages, liabilities, judgments, actions or expenses
referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities, judgments, actions or expenses in such proportion as is appropriate
to reflect the relative benefits received by the Company and the Guarantors, on
the one hand, and the Holders, on the other hand, from the Initial Placement
(which in the case of the Company shall be deemed to be equal to the total gross
proceeds from the Initial Placement as set forth on the cover page of the
Offering Memorandum of the Company dated March 27, 2002), the amount of
Liquidated Damages which did not become payable as a result of the filing of the
Registration Statement resulting in such losses, claims, damages, liabilities,
judgments, actions or expenses, and such Registration Statement, or if such
allocation is not permitted by applicable law, the relative fault of the Company
and the Guarantors on the one hand, and of the Indemnified Holder, on the other
hand, in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities, judgments, actions or expenses, as well as
any other relevant equitable considerations. The relative fault of the Company
and/or the Guarantors on the one hand and of the Indemnified Holder on the other
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by the Company or by
the Indemnified Holder and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid or payable by a party as a result of the losses, claims,
damages, liabilities, judgments, actions and expenses referred to above shall be
deemed to include, subject to the limitations set forth in the second paragraph
of Section 8(a), any legal or other fees or expenses reasonably incurred by such
party in connection with investigating or defending any action or claim.

                  The Company, the Guarantors and each Holder of Transfer
Restricted Securities agree that it would not be just and equitable if
contribution pursuant to this Section 8(c) were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to in the immediately preceding paragraph. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities, judgments, actions or expenses referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the

<PAGE>

provisions of this Section 8, none of the Holders (and its related Indemnified
Holders) shall be required to contribute, in the aggregate, any amount in excess
of the amount by which the total discount received by such Holder with respect
to the Initial Notes exceeds the amount of any damages which such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Holders' obligations to contribute pursuant to
this Section 8(c) are several in proportion to the respective principal amount
of Initial Notes held by each of the Holders hereunder and not joint.

SECTION 9. RULE 144A

                  The Company and the Guarantors each hereby agrees with each
Holder, for so long as any Transfer Restricted Securities remain outstanding, to
make available to any Holder or beneficial owner of Transfer Restricted
Securities in connection with any sale thereof and any prospective purchaser of
such Transfer Restricted Securities from such Holder or beneficial owner, the
information required by Rule 144A(d)(4) under the Securities Act in order to
permit resales of such Transfer Restricted Securities pursuant to Rule 144A.

SECTION 10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

                  No Holder may participate in any Underwritten Registration
hereunder unless such Holder (a) agrees to sell such Holder's Transfer
Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (b)
completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such underwriting arrangements.

SECTION 11. SELECTION OF UNDERWRITERS

                  The Holders of Transfer Restricted Securities covered by the
Shelf Registration Statement who desire to do so may sell such Transfer
Restricted Securities in an Underwritten Offering. In any such Underwritten
Offering, the investment banker or investment bankers and manager or managers
that will administer the offering will be selected by the Holders of a majority
in aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
reasonably satisfactory to the Company.

SECTION 12. MISCELLANEOUS

         (a)      Remedies. The Company and the Guarantors each hereby agrees
that monetary damages would not be adequate compensation for any loss incurred
by reason of a breach by it of the provisions of this Agreement and hereby
agrees to waive the defense in any action for specific performance that a remedy
at law would be adequate.

         (b)      No Inconsistent Agreements. The Company will not, and will not
permit the Guarantors to, on or after the date of this Agreement enter into any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holders in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Company's securities under any agreement in effect on the date hereof.

         (c)      Adjustments Affecting the Notes. The Company will not take any
action, or permit any change to occur, with respect to the Notes that would
materially and adversely affect the ability of the Holders to Consummate any
Exchange Offer.

<PAGE>

         (d)      Amendments and Waivers. The provisions of this Agreement may
not be amended, modified or supplemented, and waivers or consents to or
departures from the provisions hereof may not be given unless the Company has
obtained the written consent of Holders of a majority of the outstanding
principal amount of Transfer Restricted Securities. Notwithstanding the
foregoing, a waiver or consent to departure from the provisions hereof that
relates exclusively to the rights of Holders whose securities are being tendered
pursuant to the Exchange Offer and that does not affect directly or indirectly
the rights of other Holders whose securities are not being tendered pursuant to
such Exchange Offer may be given by the Holders of a majority of the outstanding
principal amount of Transfer Restricted Securities being tendered or registered;
provided that, with respect to any matter that directly or indirectly affects
the rights of any Initial Purchaser hereunder, the Company shall obtain the
written consent of each such Initial Purchaser with respect to which such
amendment, qualification, supplement, waiver, consent or departure is to be
effective.

         (e)      Notices. All notices and other communications provided for or
