this Indenture shall govern and be controlling.

     (b)  Form of Notes. The Notes shall be issued initially in global form and
shall be substantially in the form of Exhibit A attached hereto (including the
Global Note Legend thereon and the "Schedule of Exchanges of Interests in the
Global Note" attached thereto). Notes issued in definitive form shall be
substantially in the form of Exhibit A 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 or the Custodian, at the direction of the Trustee, in accordance with
instructions given by the Holder thereof as required by Section 2.06 hereof.

     (c)  Book-Entry Provisions. This Section 2.01(c) shall only apply to Global
Notes deposited with the Trustee, as custodian for the Depositary. Participants
and Indirect Participants shall have no rights under this

                                       17
<PAGE>

Indenture with respect to any Global Note held on their behalf by the Depositary
or by the Trustee as the custodian for the Depositary or under such Global Note,
and the Depositary shall be treated by the Company, the Trustee and any agent of
the Company or the Trustee as the absolute owner of such Global Note for all
purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
the Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depositary or impair, as between the Depositary and its Participants or
Indirect Participants, the Applicable Procedures or the operation of customary
practices of the Depositary governing the exercise of the rights of a holder of
a beneficial interest in any Global Note.

Section 2.02.     Execution and Authentication.
                  ----------------------------

     (a)  Two Officers shall sign the Notes for the Company by manual or
facsimile signature.

     (b)  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.

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

     (d)  The Trustee shall, upon a written order of the Company signed by an
Officer (an "Authentication Order"), authenticate Notes for original issue.

     (e)  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.

     (f)  The Company may issue Additional Notes from time to time after the
offering of the Initial Notes. The Initial Notes, the Exchange Notes and any
Additional Notes subsequently issued under this Indenture shall be treated as a
single class for all purposes under this Indenture, including, without
limitation, waivers, amendments, redemptions and offers to purchase.

Section 2.03.     Registrar and Paying Agent.
                  --------------------------

     (a)  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 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.

     (b)  The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Notes.

     (c)  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 2.04.     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, if any, or interest and Liquidated Damages, if any, on the Notes, and
shall notify the

                                       18
<PAGE>

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. 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 a Subsidiary) shall have no further
liability for the money. If the Company or a Subsidiary 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 2.05.     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 seven
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 or such
shorter time as the Trustee may allow, as the Trustee may reasonably require of
the names and addresses of the Holders and the Company shall otherwise comply
with TIA ss. 312(a).

Section 2.06.     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 will be exchanged by
the Company for Definitive Notes if (1) 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 or (2)
the Company in its sole discretion determines that the Global Notes (in whole
but not in part) should be exchanged for Definitive Notes and deliver a written
notice to such effect to the Trustee; or (3) an Event of Default shall have
occurred and be continuing. Upon the occurrence of any of the preceding events
in (1), (2) or (3) above, Definitive Notes shall be issued in denominations of
$1,000 or integral multiples thereof and 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 2.07 and 2.10 hereof. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any
portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 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 2.06(a), however, beneficial interests in a Global Note may be
transferred and exchanged as provided in Section 2.06(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 clause (i) or (ii) below, as applicable, as well as one or more of the
other following clauses, 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 Distribution Compliance Period,
     transfers of beneficial interests in the Regulation S 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 2.06(b)(i).

          (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 2.06(b)(i) above, the

                                       19
<PAGE>

     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 from a
     Participant or an Indirect Participant given to the Depositary in
     accordance with the Applicable Procedures directing the Depositary to cause
     to be issued a Definitive Note in an amount equal to the beneficial
     interest to be transferred or exchanged and (2) instructions given by the
     Depositary to the Registrar containing information regarding the Person in
     whose name such Definitive Note shall be registered to effect the transfer
     or exchange referred to in (B)(1) above. Upon consummation of an Exchange
     Offer by the Company in accordance with Section 2.06(f) hereof, the
     requirements of this Section 2.06(b)(ii) shall be deemed to have been
     satisfied upon receipt by the Registrar of the instructions contained in
     the Letter of Transmittal delivered by the Holder of such beneficial
     interests in the Restricted Global Notes. Upon satisfaction of all of the
     requirements for transfer or exchange of beneficial interests in Global
     Notes contained in this Indenture and the Notes or otherwise applicable
     under the Securities Act, the Trustee shall adjust the principal amount of
     the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

          (iii) Transfer of Beneficial Interests in a Restricted Global Note to
     Another Restricted Global Note. A beneficial interest in any Restricted
     Global Note may be transferred to a Person who takes delivery thereof in
     the form of a beneficial interest in another Restricted Global Note if the
     transfer complies with the requirements of Section 2.06(b)(ii) above and
     the Registrar receives the following:

                (A)  if the transferee will take delivery in the form of a
          beneficial interest in the 144A Global Note, then the transferor must
          deliver a certificate in the form of Exhibit B hereto, including the
          certifications in item (1) thereof;

                (B)  if the transferee will take delivery in the form of a
          beneficial interest in the Regulation S Global Note, then the
          transferor must deliver a certificate in the form of Exhibit B hereto,
          including the certifications in item (2) thereof; and

                (C)  if the transferee will take delivery in the form of a

          deliver a certificate in the form of Exhibit B hereto, including the
          certifications and certificates and Opinion of Counsel required by
          item (3) thereof, if applicable.

          (iv)  Transfer and Exchange of Beneficial Interests in a Restricted
     Global Note for Beneficial Interests in an Unrestricted Global Note. A
     beneficial interest in any Restricted Global Note may be exchanged by any
     holder thereof for a beneficial interest in an Unrestricted Global Note or
     transferred to a Person who takes delivery thereof in the form of a
     beneficial interest in an Unrestricted Global Note if the exchange or
     transfer complies with the requirements of Section 2.06(b)(ii) above and:

                (A)  such exchange or transfer is effected pursuant to the
          Exchange Offer in accordance with the Registration Rights Agreement
          and the holder of the beneficial interest to be transferred, 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;

                     (1)  if the holder of such beneficial interest in a
                Restricted Global Note proposes to exchange such beneficial
                interest for a beneficial interest in an Unrestricted Global
                Note, a certificate from such holder in the form of Exhibit C
                hereto, including the certifications in item (1)(a) thereof; or

                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 clause (D), if the
                Registrar and the Company so requests or if the Applicable
                Procedures so require, an Opinion of Counsel in form reasonably
                acceptable to the Registrar to the effect that such exchange or
                transfer is in compliance with the Securities Act and that the

                Placement Legend are no longer required in order to maintain
                compliance with the Securities Act.

          substitution thereof) shall bear the legend in substantially the
          following form:

     THE NOTES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES

PLEDGED OR OTHERWISE TRANSFERRED, IN THE ABSENCE OF SUCH REGISTRATION UNLESS THE
TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT. THE HOLDER OF THIS NOTE BY ITS ACCEPTANCE HEREOF (1)
REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN RULE
144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING
THIS NOTE IN AN "OFFSHORE TRANSACTION" PURSUANT TO RULE 904 OF REGULATION S

LAST DAY ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WERE THE OWNERS OF
THIS NOTE (OR ANY PREDECESSOR OF THIS NOTE) AND (B) SUCH LATER DATE, IF ANY, AS

OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE
IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (IV) PURSUANT
TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES
WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT OR (V) PURSUANT TO
ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS NOTE
IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED
THAT THE COMPANY, THE TRUSTEE, AND THE REGISTRAR SHALL HAVE THE RIGHT PRIOR TO
ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (IV) OR (V) TO REQUIRE THAT
AN OPINION OF COUNSEL, CERTIFICATIONS AND/OR OTHER INFORMATION SATISFACTORY TO
THE COMPANY, THE TRUSTEE AND THE REGISTRAR IS COMPLETED AND DELIVERED BY THE
TRANSFEROR. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE
RESALE RESTRICTION TERMINATION DATE. AS USED HEREIN, THE TERMS "OFFSHORE
TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM
BY REGULATION S UNDER THE SECURITIES ACT.

                (B)  Notwithstanding the foregoing, any Global Note or
          Definitive Note issued pursuant to clauses (b)(iv), (c)(ii), (c)(iii),
          (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.06 (and

GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL
OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES

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

     (i) General Provisions Relating to Transfers and Exchanges.

          (i)    To permit registrations of transfers and exchanges, the Company
     shall execute and, upon receipt of an Authentication Order in accordance
     with Section 2.02, 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 2.10, 3.06, 4.12, 4.18 and 9.05 hereof).

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

          (iv)   Neither the Registrar nor the Company shall 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

                                       28

          (v)    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.

     Notes in accordance with the provisions of Section 2.02 hereof.

Section 2.07.     Replacement Notes.
                  -----------------

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

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

Section 2.08.     Outstanding Notes.
                  -----------------

     (a)  The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those cancelled 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 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Company or an Affiliate of the
Company holds the Note; however, Notes held by the Company or a Subsidiary of
the Company shall not be deemed to be outstanding for purposes of Section
3.07(b) hereof.

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

     (c)  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.

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

Section 2.09.     Treasury Notes.
                  --------------

     In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, or by any Person directly or indirectly controlling

                                       29
<PAGE>

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

Section 2.10.     Temporary Notes.
                  ---------------

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

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

Section 2.11.     Cancellation.
                  ------------

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

Section 2.12.     Defaulted Interest.
                  ------------------

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

Section 2.13.     CUSIP or ISIN Numbers.
                  ---------------------

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

Section 2.14.     Liquidated Damages.
                  ------------------

     If Liquidated Damages are payable by the Company pursuant to the
Registration Rights Agreement and paragraph 1 of the Notes, the Company shall
deliver to the Trustee a certificate to that effect stating (i) the amount of
such Liquidated Damages that is payable and (ii) the date on which such interest
is payable. Unless and until a Responsible Officer of the Trustee receives such
a certificate or instruction or direction from the Holders in accordance with
the terms of the Indenture, the Trustee may assume without inquiry that no
Liquidated Damages is payable. The foregoing shall not prejudice the rights of
the Holders with respect to their entitlement to

                                       30
<PAGE>

Liquidated Damages as otherwise set forth in this Indenture or the Notes and
pursuing any action against the Company directly or otherwise directing the
Trustee to take any such action in accordance with the terms of this Indenture
and the Notes. If the Company has paid Liquidated Damages directly to the
persons entitled to it, the Company shall deliver to the Trustee a certificate
setting forth the particulars of such payment.

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 45
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 at any time, the Trustee
shall select the Notes to be redeemed among the Holders of the Notes in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not so listed, on a
pro rata basis, by lot or in accordance with any other method the Trustee
considers fair and appropriate. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

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

Section 3.03.     Notice of Redemption.
                  --------------------

     At least 30 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.

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

     (a)  the redemption date;

     (b)  the redemption price or if the redemption is made pursuant to Section
3.07(b) a calculation of 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 shall be issued 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;

                                       31
<PAGE>

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

     (g)  the paragraph of the Notes 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, or such shorter period
allowed by the Trustee, 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 this Section 3.03.

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.
                  ---------------------------

     On or before 11:00 a.m. on any 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 and Liquidated Damages, if any,
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

Holder at the expense of the Company a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

issued under this Indenture at a redemption price equal to 110.375% of the
principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on the relevant
Interest Payment Date) with the net cash proceeds of any Qualified Equity
Offering of the Company's common stock; provided, however, that after giving
effect to any such redemption, at least 65% of the aggregate principal amount of
the Notes issued on the Issue Date (excluding Notes held by the Company and its
Subsidiaries) remains outstanding immediately after the occurrence of such
redemption. Any such redemption shall be made within 90 days of such Qualified
Equity Offering upon not less than 30 nor more than 60 days' prior notice.

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

be required to commence an offer to all Holders to purchase Notes (an "Asset
Sale Offer"), it shall follow the procedures specified below.

     (b)  The Asset Sale Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Issuer shall purchase the principal amount of Notes required to be
purchased pursuant to Section 4.12 hereof (the "Offer Amount") or, if less than
the Offer Amount has been tendered, all Notes tendered in response to the Asset
Sale Offer. Payment for any Notes so purchased shall be made in the same manner
as interest payments are made.

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

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

          (i)    that the Asset Sale Offer is being made pursuant to this
     Section 3.09 and Section 4.12 hereof and the length of time the Asset Sale
     Offer shall remain open;

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

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

          (iv)   that, unless the Issuer defaults in making such payment, any
     Note accepted for payment pursuant to the Asset Sale Offer shall cease to
     accrue interest and Liquidated Damages, if any, after the Purchase Date;

                                       33

     Asset Sale Offer may elect to have Notes purchased in integral multiples of
     $1,000 only;

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

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

          (viii) that, if the aggregate principal amount of Notes surrendered
     by Holders exceeds the Offer Amount, the Issuer shall select the Notes to
     be purchased on a pro rata basis (with such adjustments as may be deemed
     appropriate by the Issuer so that only Notes in denominations of $1,000 or
     integral multiples thereof shall be purchased); and

          (ix)   that Holders whose Notes were purchased only in part shall be
     issued new Notes equal in principal amount to the unpurchased portion of
     the Notes surrendered (or transferred by book-entry transfer).

     On or before the Purchase Date, the Issuer shall, to the extent lawful,
accept for payment, on a pro rata basis to the extent necessary, the Offer
Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer,
or if less than the Offer Amount has been tendered, all Notes tendered, and
shall deliver to the Trustee an Officers' Certificate stating that such Notes or
portions thereof were accepted for payment by the Issuer in accordance with the
terms of this Section 3.09. The Issuer, the Depositary or the Paying Agent, as
the case may be, shall promptly (but in any case not later than five Business
Days after the Purchase Date) mail or deliver to each tendering Holder an amount
equal to the purchase price of the Notes tendered by such Holder and accepted by
the Issuer for purchase, and the Issuer shall promptly issue a new Note, and the
Trustee, upon written request from the Issuer shall authenticate and mail or
deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer
shall publicly announce the results of the Asset Sale Offer on the Purchase
Date.

     Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Section 3.01 through 3.06 hereof.

application of the net proceeds therefrom), as if the additional Indebtedness
had been incurred or the preferred stock or Disqualified Stock had been issued,
as the case may be, at the beginning of such four-quarter period.

     (b)  Paragraph (a) of this Section 4.09 will not prohibit the incurrence of
any of the following items of Indebtedness (collectively, "Permitted Debt"):

          (i)    the incurrence by the Company of additional Indebtedness and
     letters of credit under one or more Credit Facilities and Guarantees
     thereof by the Subsidiary Guarantors; provided that the aggregate principal
     amount of all Indebtedness of the Company and its Restricted Subsidiaries
     incurred pursuant to this clause (i) (with letters of credit being deemed
     to have a principal amount equal to the maximum potential liability of the
     Company and its Restricted Subsidiaries thereunder) does not exceed an
     amount equal to $75.0 million less the aggregate amount of Asset Sale
     Proceeds applied by the Company and its Restricted Subsidiaries since the
     date hereof to repay Indebtedness thereunder or to permanently reduce the
     availability of revolving credit Indebtedness pursuant to Section 4.12;

          (ii)   the incurrence by the Company and its Restricted Subsidiaries
     of the Existing Indebtedness;

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

          (iv)   the incurrence by the Company or any of the Subsidiary
     Guarantors of Indebtedness represented by Capital Lease Obligations,
     mortgage financings or purchase money obligations, in each case

                                       37
<PAGE>

     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 Company's business or the business of such Subsidiary Guarantor, in
     an aggregate principal amount, including all Permitted Refinancing
     Indebtedness incurred to refund, refinance or replace any Indebtedness
     incurred pursuant to this clause (iv), not to exceed $10.0 million at any
     time outstanding;

          (v)    the incurrence by the Company or any of its Restricted
     Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the
     net proceeds of which are used to refund, refinance or replace Indebtedness
     (other than intercompany Indebtedness) that was incurred under clause (a)
     of this Section 4.09 or clauses (ii), (iii), (iv), (x) or (xi) of this
     Section 4.09(b);

          (vi)   the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness owed to the Company or any of the
     Subsidiary Guarantors; provided, however, that:

                (A)  if the Company 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;

                (B)  if a Subsidiary Guarantor is the obligor on such
          Indebtedness, such Indebtedness is expressly subordinated to the prior
          payment in full in cash of such Subsidiary Guarantor's Subsidiary
          Guarantee; and

                (C)  (1) 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 Subsidiary Guarantor and (2) any sale or other
          transfer of any such Indebtedness to a Person that is not either the
          Company or a Subsidiary Guarantor shall be deemed, in each case, to
          constitute an incurrence of such Indebtedness by the Company or such
          Subsidiary Guarantor, as the case may be, that was not permitted by
          this clause (vi);

          (vii)  the incurrence by the Company or any of its Restricted
     Subsidiaries of Hedging Obligations that are incurred in the normal course
     of business for the purpose of fixing or hedging currency, commodity or
     interest rate risk (including with respect to any floating rate
     Indebtedness that is permitted by the terms hereof to be outstanding in
     connection with the conduct of the Company's respective businesses and not
     for speculative purposes);

          (viii) the guarantee by the Company or any of the Subsidiary
     Guarantors of Indebtedness of the Company or of one of its Restricted
     Subsidiaries that was permitted to be incurred by another provision of this
     covenant;

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

          (x)    unsecured Indebtedness of the Company payable to one or more
     sellers of any Person acquired by the Company or any of its Restricted
     Subsidiaries, incurred in connection with such acquisition in compliance
     with the terms hereof, not to exceed $20.0 million in the aggregate at any
     one time outstanding and in each case subordinated in right of payment to
     the Notes and the Subsidiary Guarantees; and

          (xi)   the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) at any time outstanding, including all
     Permitted Refinancing Indebtedness incurred to refund, refinance or replace
     any Indebtedness incurred pursuant to this clause (xi), not to exceed $30.0
     million (which amount may be incurred, in whole

                                       38
<PAGE>

     or in part, under any of the Credit Facilities); provided that no more than
     $10.0 million shall be incurred by a Restricted Subsidiary that is not a
     Subsidiary Guarantor.

     (c)  For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (i) through (xi) of
Section 4.09(b)as of the date of incurrence thereof or is entitled to be
incurred pursuant to clause (a) of this Section 4.09, the Company shall, in its
sole discretion, at the time the proposed Indebtedness is incurred, (x) classify
all or a portion of that item of Indebtedness on the date of its incurrence
under either the clause (a) of this Section 4.09 or under any category of
Permitted Debt, (y) reclassify at a later date all or a portion of that or any
other item of Indebtedness as being or having been incurred in any manner that
complies with this Section 4.09 and (z) elect to comply with this Section 4.09
and the applicable definitions in any order.

     (d)  The Company shall not incur, create, issue, assume, guarantee or
otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Senior Debt of the Company and not subordinate or junior
in right of payment to the Notes; provided, however, that no Indebtedness of the
Company will be deemed to be contractually subordinated in right of payment
solely by virtue of being unsecured. No Subsidiary 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 Subsidiary
Guarantor and not subordinate or junior in right of payment to such Subsidiary
Guarantor's Subsidiary Guarantee; provided, however, that no Indebtedness of a
Subsidiary Guarantor will be deemed to be contractually subordinated in right of
payment solely by virtue of being unsecured.

Section 4.10.     Restricted Payments.
                  -------------------

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly:

     (a)  declare or pay any dividend or make any other payment or distribution
on account of the Company's Equity Interests (including, without limitation, any
payment in connection with any merger or consolidation involving the Company) or
to the direct or indirect holders of the Company's Equity Interests in their
capacity as such (other than dividends or distributions payable in the Company's
Equity Interests (other than Disqualified Stock) or to the Company);

     (b)  purchase, redeem or otherwise acquire or retire for value (including,
without limitation, in connection with any merger or consolidation involving the
Company) any of the Company's Equity Interests;

     (c)  make any payment on or with respect to, or purchase, redeem, defease
or otherwise acquire or retire for value any of the Company's or its Restricted
Subsidiaries' Subordinated Indebtedness, except a payment of interest or
principal at the Stated Maturity thereof; or

     (d)  make any Restricted Investment,

(all such payments and other actions set forth in these clauses (a) through (c)
above being collectively referred to as "Restricted Payments"), unless, at the
time of and after giving effect to such Restricted Payment:

     (a)  no Default or Event of Default has occurred and is continuing or would
occur as a consequence of such Restricted Payment; and

     (b)  the Company would, at the time of such Restricted Payment and after
giving pro forma effect thereto as if such Restricted Payment 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 Section 4.09(a); and

                                       39
<PAGE>

     (c)  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),
(3) and (4) of the next paragraph), is less than the sum, without duplication,
of:

          (i)   50% of the Company's Consolidated Net Income for the period
     (taken as one accounting period) from the beginning of the first fiscal
     quarter commencing after the date hereof to the end of the Company's most
     recently ended fiscal quarter for which internal financial statements are
     available 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

          (ii)  100% of the aggregate net cash proceeds received by the Company
     since the date hereof as a contribution to its common equity capital or
     from the issue or sale of its Equity Interests (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

          (iii) 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 (1) the cash return of capital with respect to such
     Restricted Investment (less the cost of disposition, if any) and (2) the
     initial amount of such Restricted Investment.

     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 of the dividend, if at the date of declaration the dividend payment
would have complied with the provisions hereof;

     (2)  the redemption, repurchase, retirement, defeasance or other
acquisition of any of the Company's or its Restricted Subsidiaries' Subordinated
Indebtedness or of any of the Company's Equity Interests in exchange for, or out
of the net cash proceeds of the substantially concurrent sale (other than to any
of the Company's Restricted Subsidiaries) of, the Company's Equity Interests
(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 will be excluded from clause (c)(ii) of the
preceding paragraph;

     (3)  the defeasance, redemption, repurchase or other acquisition of
Subordinated Indebtedness of the Company or any of its Restricted Subsidiaries
with the net cash proceeds from an incurrence of Permitted Refinancing
Indebtedness;

     (4)  the repurchase, redemption or other acquisition or retirement for
value of any of the Company's Equity Interests held by any member of the
Company's (or any of the Company's Restricted Subsidiaries') management pursuant
to any management equity subscription agreement, stock option agreement or
similar agreement; provided that the aggregate price paid for all such
repurchased, redeemed, acquired or retired Equity Interests may not exceed
$1,000,000 in any twelve-month period; and

     (5)  other Restricted Payments in an aggregate amount since the Issue Date
not to exceed $10.0 million.

     The amount of all Restricted Payments (other than cash) will be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
Section 4.10 will be determined by the Board of Directors of the Company whose
resolutions with respect thereto will 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 $5.0 million. Not later than the date of making any

                                       40
<PAGE>

Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by this Section 4.10 were
computed, together with a copy of any fairness opinion or appraisal required by
this Indenture.

Section 4.11.     Liens.
                  -----

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

Section 4.12.     Asset Sales.
                  -----------

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

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

           (ii) the fair market value, if greater than $2.0 million, is
     determined by the Company's Board of Directors and evidenced by a
     resolution of the Board of Directors set forth in an Officer's Certificate
     delivered to the Trustee; and

           (iii) at least 75% of the consideration received in the Asset Sale by
     the Company or such Restricted Subsidiary is in the form of cash, Cash
     Equivalents or Replacement Assets.

     (b)  For purposes of this Section 4.12, each of the following will be
deemed to be cash:

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

           (ii) any securities, notes or other obligations received by the
     Company or any such Restricted Subsidiary from such transferee that are
     contemporaneously, subject to ordinary settlement periods, converted by the
     Company or such Restricted Subsidiary into cash, to the extent of the cash
     received in that conversion.

     (c)  Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply those Net Proceeds at its option:

           (i) to repay Senior Debt and, if the Senior Debt repaid is revolving
     credit Indebtedness, to correspondingly permanently 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; or

           (iii) to acquire other long-term assets that are used or useful in a
     Permitted Business.

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

     (d)  Any Net Proceeds from Asset Sales that are not applied or invested as
provided in Section 4.12(c) will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $5.0 million,

                                       41
<PAGE>

the Company shall make 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 herein with respect to offers to purchase
or redeem with the proceeds of sales of assets to purchase the maximum principal
amount of Notes and such other pari passu Indebtedness that may be purchased out
of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to
100% of the principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, to the date of purchase, and shall be payable in
cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Company may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and
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 as described in Article 3 hereof. Upon
completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset
at zero.

     (e)  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 those 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 Sale
provisions of this Indenture, the Company shall comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under this Section 4.12 by virtue of such conflict.

Section 4.13.     Dividend and Other Payment Restrictions Affecting Restricted
                  -------------------------------------------------------------
                  Subsidiaries.
                  ------------

     The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, create or permit to exist or become effective any
consensual encumbrance or restriction on the right of any Restricted Subsidiary
to:

     (a)  pay dividends or make any other distributions on or in respect of 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 other Restricted Subsidiary,

     (b)  make any loans or advances to the Company or any other Restricted
Subsidiary or

     (c)  transfer any of its Property to the Company or any other Restricted
Subsidiary.

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

          (i)   agreements as in effect on the date hereof or subsequent
     agreements relating to our Indebtedness or Indebtedness of any Subsidiary
     Guarantors and any amendments, modifications, restatements, renewals,
     increases, supplements, refundings, replacements or refinancings of those
     agreements; provided that the amendments, modifications, restatements,
     renewals, increases, supplements, refundings, replacement or refinancings
     are not materially more restrictive, taken as a whole, with respect to such
     dividend and other payment restrictions than those contained in those
     agreements on the date hereof;

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

          (iii)  applicable law;

          (iv)   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 or Capital Stock 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;

                                       42

          (v)    customary non-assignment provisions in leases entered into in
     the ordinary course of business and consistent with past practices;

     ordinary course of business that impose restrictions on that property of
     the nature described in clause (c) of the preceding paragraph;

          (vii)  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;

          (viii) Permitted Refinancing Indebtedness; provided that the
     restrictions contained in the agreements governing such Permitted
     Refinancing Indebtedness are not materially more restrictive, taken as a
     whole, than those contained in the agreements governing the Indebtedness
     being refinanced;

          (ix)   Liens securing Indebtedness otherwise permitted to be incurred
     under Section 4.11 that limit the right of the debtor to dispose of the
     assets subject to such Liens; and

          (x)   provisions with respect to the disposition or distribution of
     assets or property in joint venture agreements, asset sale agreements,
     stock sale agreements and other similar agreements entered into in the
     ordinary course of business.

Section 4.14.     Transactions with Affiliates.
                  ----------------------------

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of their respective 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:

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

     (b)  the Company delivers to the trustee:

          (i)   with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of $2.5

     covenant and that such Affiliate Transaction has been approved by a
     majority of the disinterested members of the Board of Directors; and

          (ii)  with respect to any Affiliate Transaction or series of related
     Affiliate Transactions involving aggregate consideration in excess of $10.0
     million, an opinion as to the fairness to the Holders of such Affiliate
     Transaction from a financial point of view issued by an accounting,
     appraisal or investment banking firm of national standing.

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

     (a)  any employment agreement entered into by the Company or any of its
Restricted Subsidiaries in the ordinary course of business and consistent with
its past practice or the past practice of such Restricted Subsidiary;

     (g)  any agreement (including any certificate of designations relating to
Capital Stock) as in effect as of the date hereof or any amendment thereto or
any transaction contemplated thereby (including pursuant to any amendment
thereto) in any replacement agreement thereto so long as any such amendment or
replacement agreement is not more disadvantageous to the Holders in any material
respect than the original agreement as in effect on the date hereof; and

     (h)  the payment of dividends on the Redeemable Preferred Stock in
accordance with the terms of such preferred stock.

Section 4.15.     Sale and Leaseback Transactions.
                  -------------------------------

     The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale and leaseback transaction; provided that
the Company or any Subsidiary Guarantor may enter into a sale and leaseback

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 and (b) incurred a Lien to secure such
Indebtedness pursuant to Section 4.11;

     (b)  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,
of the property that is the subject of that sale and leaseback transaction; and

     (c)  the transfer of assets in that sale and leaseback transaction is
permitted by, and the Company applies the proceeds of such transaction in

Section 4.16.     Issuances and Sales of Capital Stock of Restricted
                  ---------------------------------------------------
                  Subsidiaries.

     The Company (a) shall not, and shall not permit any of its Restricted
Subsidiaries to, transfer, convey, sell, lease or otherwise dispose of any
Capital Stock of any of its Restricted Subsidiaries to any Person (other than to
the Company or another one of its Restricted Subsidiaries), unless (i) such
transfer, conveyance, sale, lease or other disposition is of all the Capital
Stock of such Restricted Subsidiary and (ii) the Net Proceeds from such
transfer, conveyance, sale, lease or other disposition are applied in accordance
with Section 4.12; provided that this clause (a) shall not apply to any pledge
of Capital Stock of any Restricted Subsidiary of the Company securing
Indebtedness under Credit Facilities, including the Credit Agreement, or any
exercise of remedies in connection therewith, and (b) will not permit any of its
Restricted Subsidiaries to issue any of its Equity Interests (other than, if
necessary, shares of its Capital Stock constituting directors' qualifying
shares) to any Person other than the Company or another one of its Restricted
Subsidiaries.

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 properly designated will be deemed to
be an Investment made as of the time of the designation and will reduce the
amount available for Restricted Payments under the first paragraph of Section
4.10 or Permitted Investments, as determined by the Company. That designation
will only be permitted if the Investment

                                       44
<PAGE>

would be permitted at that time and if the Restricted Subsidiary otherwise meets
the definition of an Unrestricted Subsidiary. The Board of Directors may
redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the
redesignation would not cause a Default.

Section 4.18.     Repurchase at the Option of Holders Upon a Change of Control.
                  ------------------------------------------------------------

     (a)  Upon the occurrence of a Change of Control, each Holder shall have the
right to require the Company to repurchase all or any part (equal to $1,000 or
an integral multiple of $1,000) of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") at a purchase price (the "Change
of Control Purchase Price") equal to 101% of the principal amount thereof, plus
accrued and unpaid interest and Liquidated Damages if any, to the purchase date
(subject to the right of Holders on the relevant record date to receive interest
due on the relevant Interest Payment Date).

     Subject to clause (c) below, within 10 days following any Change of
Control, the Company shall mail a notice to the Trustee and each holder:

          (i)   send, by first-class mail, with a copy to the Trustee, to each
     Holder, at such Holder's address appearing in the securities register
     maintained in respect of the Notes by the Registrar (the "Security
     Register"):

                (A)  that a Change of Control has occurred and a Change of
          Control Offer is being made pursuant to Section 4.18 and that all
          Notes timely tendered will be accepted for payment;

                (B)  the Change of Control Purchase Price and the purchase date,
          which shall be, subject to any contrary requirements of applicable
          law, a business day no earlier than 30 days nor later than 60 days
          from the date such notice is mailed;

                (C)  the circumstances and relevant facts regarding the Change
          of Control (including information with respect to pro forma historical
          income, cash flow and capitalization after giving effect to the Change
          of Control); and

                (D)  the procedures that Holders must follow in order to tender
          their Notes (or portions thereof) for payment, and the procedures that
          Holders must follow in order to withdraw an election to tender Notes
          (or portions thereof) for payment.

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

     (b)  On the Change of Control Payment Date, the Company shall, to the
extent lawful:

          (i)   accept for payment all Notes or portions of Notes properly
     tendered pursuant to the Change of Control Offer;

          (ii)  deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all Notes or portions of Notes properly
     tendered; and

                                       45
<PAGE>

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

     The Paying Agent shall promptly mail to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book-entry) to
each Holder a new note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each new note will be in a
principal amount of $1,000 or an integral multiple of $1,000.

     (c)  Prior to complying with any of the provisions of this Section 4.18,
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 covenant. 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.

     (d)  The provisions described above that require us to make a Change of
Control Offer following a Change of Control will be applicable whether or not
any other provisions of the indenture are applicable. Except as described above
with respect to a Change of Control, this Indenture does not contain provisions
that permit the Holders of the Notes to require that the Company repurchase or
redeem the notes in the event of a takeover, recapitalization or similar
transaction.

Section 4.19.     Additional Subsidiary Guarantees
                  --------------------------------

     If the Company or any of its Restricted Subsidiaries acquires or creates
another Domestic Subsidiary after the date hereof, then that newly acquired or
created Domestic Subsidiary will execute and deliver to the Trustee a
supplemental indenture providing for a Subsidiary Guarantee and deliver an
Opinion of Counsel satisfactory to the Trustee within 10 Business Days of the
date on which it was acquired or created; provided, however, that the foregoing
shall not apply to Subsidiaries that have properly been designated as
Unrestricted Subsidiaries in accordance with this Indenture for so long as they
continue to constitute Unrestricted Subsidiaries.

Section 4.20.     Designation as "Designated Senior Debt"
                  ---------------------------------------

     The Company hereby designates the Notes as "Designated Senior Debt" as that
term is defined in the Senior Subordinated Note Indenture. Each of the
Subsidiary Guarantors hereby designates its Subsidiary Guarantee as "Designated
Guarantor Senior Debt" as that term is defined in the Senior Subordinated Note
Indenture.

Section 4.21.     Business Activities.
                  -------------------

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

additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set
forth in Section 4.09.

     In addition, the Company may not, directly or indirectly, lease all or

                  ---------------------------------

Section 6.01.     Events of Default.
                  -----------------

     Each of the following is an "Event of Default:"

          (i)    default for 30 days in the payment when due of interest on, or
     Liquidated Damages with respect to, the Notes;

     Indebtedness for money borrowed by the Company or any of 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 hereof, 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"); or

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

          and, in each case, the principal amount of any such Indebtedness,
     together with the principal amount of any other such Indebtedness under

     accelerated, aggregates $10.0 million or more;

          (vii)  failure by the Company or any of its Restricted Subsidiaries
     to pay final judgments (to the extent not covered by insurance) aggregating
     in excess of $10.0 million, which judgments are not paid, discharged or
     stayed for a period of 60 consecutive days;

          (viii) except as permitted by 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
     Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
     Guarantor, shall deny or disaffirm its obligations under its Subsidiary
     Guarantee; and

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

                 (A)  commences a voluntary case,

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

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

          creditors, or

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

          Significant Subsidiaries in an involuntary case; or

                                       48
<PAGE>

                 (B)  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 Subsidiaries; or

                 (C)  orders the liquidation of the Company or any of its
          Significant Subsidiaries;

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

Section 6.02.     Acceleration.
                  ------------

     If an Event of Default (other than an Event of Default specified in clauses
(ix) or (x) of Section 6.01 hereof, with respect to the Company, any Subsidiary
that is a Significant Subsidiary or any group of Subsidiaries that, taken
together would constitute a Significant Subsidiary), shall have occurred and be
continuing, the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Notes then outstanding may declare to be immediately due
and payable the principal amount of all the Notes then outstanding, plus accrued
but unpaid interest and Liquidated Damages, if any, to the date of acceleration.
In the case of an Event of Default specified in clauses (ix) or (x) of Section
6.01 hereof, with respect to the Company, any Subsidiary that is a Significant
Subsidiary or any group of Subsidiaries that, taken together would constitute a
Significant Subsidiary shall occur, such amount with respect to all the Notes
will become due and payable immediately without any declaration or other act on
the part of the Trustee or the Holders. Holders may not enforce this Indenture
or the Notes except as provided in this Indenture. Subject to the limitations
described in this Article 6, Holders of a majority in aggregate principal amount
of the then outstanding Notes may direct the Trustee in its exercise of any
trust or power. The Trustee may withhold from Holders notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal, premium, if any, or interest or Liquidated Damages, if
any) if it determines that withholding notice is in their interest.

     In the case of an Event of Default occurring by reason of any willful
action or inaction taken or not taken by the Company or on the Company's behalf
with the intention of avoiding payment of the premium that the Company would
have been required to pay if the Company had then elected to redeem the notes
pursuant to Section 3.07 hereof, an equivalent premium will 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 prior to February 15, 2006, by
reason of any willful action or inaction taken or not taken by the Company or on
the Company's behalf with the intention of avoiding the prohibition on
redemption of the Notes prior to February 15, 2006, then the premium specified
in Section 3.07 will also become immediately due and payable to the extent
permitted by law upon 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, and
interest and Liquidated Damages, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

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

Section 6.04.     Waiver of Past Defaults.
                  -----------------------

     Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium, if any, or interest or Liquidated Damages
on, the Notes; provided, however, that after any acceleration, but before a
judgment or decree based on acceleration is obtained by the Trustee, the Holders
of a majority in aggregate

                                       49
<PAGE>

principal amount of the Notes then outstanding may rescind and annul such
acceleration if all Events of Default, other than the nonpayment of accelerated
principal, premium or interest or Liquidated Damages, have been cured or waived
as provided in this Indenture. 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.
                  -------------------

     Subject to Section 7.01, in case an Event of Default shall occur and be
continuing, the Trustee will be under no obligation to exercise any of its
rights or powers under this Indenture at the request or direction of any of the
Holders, unless such Holders shall have offered to the Trustee reasonable
indemnity. Subject to Section 7.07, the Holders of a majority in aggregate
principal amount of the Notes then outstanding will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Trustee or exercising any trust or power conferred on the Trustee with
respect to the Notes.

Section 6.06.     Limitation on Suits.
                  -------------------

     No Holder will have any right to institute any proceeding with respect to
this Indenture, or for the appointment of a receiver or trustee, or for any
remedy thereunder, unless:

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

     (b)  Holders of at least 25% in aggregate principal amount of the Notes
then outstanding have made written request and offered reasonable indemnity to
the Trustee to institute such proceeding as trustee, and

     (c)  the Trustee shall not have received from the Holders of a majority in
aggregate principal amount of the Notes then outstanding a direction
inconsistent with such request and shall have failed to institute such
proceeding within 60 days.

     The preceding limitations do not apply to a suit instituted by a Holder for
enforcement of payment of the principal of, and premium, if any, or interest or
Liquidated Damages on, a Note on or after the respective due dates expressed in
such Note.

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

Section 6.07.     Rights of Holders to Receive Payment.
                  ------------------------------------

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

Section 6.08.     Collection Suit by Trustee.
                  --------------------------

     If an Event of Default specified in clauses (i) or (ii) of Section 6.01
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, and interest and Liquidated Damages, if
any, remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

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

Section 6.10.     Priorities.
                  ----------

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

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

     Second: to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, and 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, and 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 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 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07 hereof, or a suit by Holders of more than 10% in principal amount of the
then outstanding Notes.

                  -----------------

     (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 man would
exercise or use under the circumstances in the conduct of his own affairs.

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

          (1)  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

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

     other facts stated therein or otherwise verify the contents thereof).

     (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:

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

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

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

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

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

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

                  ----------------------------

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may otherwise deal with the Company or any Affiliate of the
Company with the same rights it would have if it were not Trustee. However, in
the event that the Trustee acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the 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 Section 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

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 a notice of the Default
or Event of Default within 90 days after it occurs unless such Default or Event
of Default has since been cured. Except in the case of a Default or Event of
Default in payment of

                                       53
<PAGE>

principal of, premium, if any, or interest or Liquidated Damages, if any, 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.

Section 7.06.     Reports by Trustee to Holders.
                  -----------------------------

     Within 60 days after each May 15 beginning with May 15, 2002, and for so
long as Notes remain outstanding, the Trustee shall mail to the Holders 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 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.

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
agreed to in writing. 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 the Trustee or any predecessor Trustee against
any and all losses, claims, damages, penalties, fines, liabilities or expenses,
including incidental and out-of-pocket expenses and reasonable attorneys fees
("losses") incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and
expenses of enforcing this Indenture against the Company (including this Section
7.07) and defending itself against any claim (whether asserted by the Company or
any Holder or any other person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such losses may be attributable to its gross negligence 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 Company need not reimburse
any expense or indemnify against any loss liability or expense incurred by the
Trustee through the Trustee's own willful misconduct, gross negligence or bad
faith.

     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, premium, if any, and
interest 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 clauses (ix) or (x) of Section 6.01 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.

     The Trustee may resign in writing at any time upon 30 days prior notice to
the Company 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 at least 10% in principal amount of the then outstanding Notes
may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     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. Subject to the Lien provided for in Section 7.07 hereof, the retiring
Trustee shall promptly transfer all property held by it as Trustee to the
successor Trustee; provided, however, that all sums owing to the Trustee
hereunder shall have been paid. Notwithstanding replacement of the Trustee
pursuant to this Section 7.08, the Company's obligations under Section 7.07
hereof shall continue for the benefit of the retiring Trustee.

Section 7.09.     Successor Trustee by Merger, etc.
                  ---------------------------------

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

Section 7.10.     Eligibility; Disqualification.
                  -----------------------------

     There shall at all times be a Trustee hereunder that is a Person organized
and doing business under the laws of the United States of America or of any
state thereof that is authorized under such laws to exercise corporate trustee
power, that is subject to supervision or examination by federal or state
authorities and that has a combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

                                       55
<PAGE>

     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 8.

                    LEGAL 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 8.

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 on the
date the conditions set forth below are satisfied (hereinafter, "Legal
Defeasance"). For this purpose, Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire Debt represented by the
outstanding Notes, 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 solely from the trust fund described in Section
8.04 hereof, and as more fully set forth in such Section, payments in respect of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on such Notes when such payments are due, (b) the Company's obligations with
respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights,
powers, trusts, duties and immunities of the Trustee hereunder and the Company's
obligations in connection therewith and (d) this Article 8. If the Company
exercises under Section 8.01 hereof the option applicable to this Section 8.02,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
payment of the Notes may not be accelerated because of an Event of Default.
Subject to compliance with this Article 8, 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 4.05, 4.06 and 4.08
through 4.18 hereof, and the operation of Section 5.01(d) hereof, 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. If the Company exercises under Section 8.01 hereof the
option applicable to this Section 8.03, subject to the satisfaction of the

                                       56
<PAGE>

conditions set forth in Section 8.04 hereof, payment of the Notes may not be
accelerated because of an Event of Default specified in clauses (iii) and (iv)
(with respect to the covenants contained in Sections 4.05, 4.06 and 4.08 through
4.18 hereof), (v), (vi), (vii) and (viii) (but in the case of clauses (ix) and
(x) of Section 6.01 hereof, with respect to Significant Subsidiaries only).

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.

benefit of the Holders of the Notes, cash in U.S. dollars, non-callable
Government Securities, or a combination of cash in U.S. dollars and non-callable
Government Securities, in amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the
principal of, or interest and premium 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 Legal Defeasance, the Company delivers to the Trustee
an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a)
the Company has received from, or there has been published by, the Internal
Revenue Service a ruling or (b) since the date 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 will 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 Covenant Defeasance, the Company delivers 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 has occurred and is continuing on the
date of such deposit (other than a Default or Event of Default resulting from
the borrowing of funds to be applied to such deposit);

     (e)  such Legal Defeasance or Covenant Defeasance will not result in a
breach or violation of, or constitute a default under any material agreement or
instrument (including, without limitation, the Credit Agreement, but excluding
the indenture) to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries may is bound;

     (f)  the Company delivers 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 Company's other creditors with the intent of
defeating, hindering, delaying or defrauding the Company's creditors or others;
and

     (g)  the Company delivers 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 U.S. Government Obligations
(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 all sums due and to become due thereon in respect
of principal, premium, if any, and interest and Liquidated Damages, if any,, but
such money need not be segregated from other funds except to the extent required
by law.

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

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

Section 8.06.     Repayment to Company.
                  --------------------

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium, if any, or
interest or Liquidated Damages on any Note and remaining unclaimed for two years
after such principal, and premium, if any, or interest or Liquidated Damages 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 shall
thereafter, as an unsecured creditor, look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company cause to be published once, in The New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a date specified therein, which shall not be less than 30 days from the
date of such notification or publication, any unclaimed balance of such money
then remaining 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 U.S. Government Obligations 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 or Liquidated Damages on
any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders to receive such payment from the money
held by the Trustee or Paying Agent.

may be therein contained, but the Trustee shall not be obligated to enter into
such amended or supplemental Indenture that affects its own rights, duties or
immunities under this Indenture or otherwise.

Section 9.02.     With Consent of Holders of Notes.
                  --------------------------------

     Except as provided below in this Section 9.02, the Company and the Trustee
may amend or supplement this Indenture and the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal
amount of the Notes, including Additional Notes, if any, then outstanding voting
as a single class (including consents obtained in connection with a tender offer
or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04
and 6.07 hereof, any existing Default or Event of Default (other than a Default
or Event of Default in the payment of the principal of, premium, if any, or
interest or Liquidated Damages on the Notes, except a payment default resulting
from an acceleration that has been rescinded) or compliance with any provision
of this Indenture or the Notes may be waived with the consent of the Holders of
a majority in principal amount of the then outstanding Notes, including
Additional Notes, if any, voting as a single class (including consents obtained
in connection with a tender offer or exchange offer for, or purchase of, the
Notes).

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

     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 their 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.

                                       59
<PAGE>

     It shall not be necessary for the consent of the Holders under this Section
9.02 to approve the particular form of any proposed amendment 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 to such Holder's address
appearing in the Security Register a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such amended or supplemental Indenture or waiver. Subject to Sections 6.04
and 6.07 hereof, the Holders of a majority in aggregate principal amount of the
Notes, including Additional Notes, if any, then outstanding voting as a single
class may waive compliance in a particular instance by the Company with any
provision of this Indenture or the Notes. Without the consent of each Holder, 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 with respect to the redemption of the Notes;

     (c)  make any change in the provisions of Sections 4.12 or 4.18;

     (d)  reduce the rate of or change the time for payment of interest on any
note,

     (e)  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
recission of acceleration of the Notes by the Holders of at least a majority in
aggregate principal amount of the Notes and a waiver of the payment default that
resulted from such acceleration);

     (f)  make any Note payable in money other than that stated in the Note,

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

     (h)  waive a redemption payment with respect to any Note;

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

     (j)  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 is a continuing consent by the Holder of a Note and every subsequent
Holder that evidences the same debt as the consenting Holder's Note, even if
notation of the consent is not made on any Note. However, any such Holder or
subsequent Holder may revoke the consent as to 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.

<PAGE>

Section 9.05.     Notation on or Exchange of Notes.
                  --------------------------------

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

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

Section 9.06.     Trustee to Sign Amendments, etc.
                  --------------------------------

     The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign an amendment or supplemental Indenture until the Board of Directors
approves it. In executing any amended or supplemental indenture, the Trustee
shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully
protected in relying upon an Officer's Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture and that such amended or supplemental
indenture is the legal, valid and binding obligations of the Company enforceable
against it in accordance with its terms, subject to customary exceptions and
that such amended or supplemental indenture complies with the provisions hereof
(including Section 9.03).

                                  ARTICLE 10.

                              SUBSIDIARY GUARANTEES

Section 10.01.    Guarantee.
                  ---------

     Subject to this Article 10, each of the Subsidiary 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 premium, if any, and interest on the Notes shall be promptly
paid in full when due, whether at maturity, by acceleration, redemption or
otherwise, and interest on the overdue principal of and interest on the Notes,
if any, if lawful, and all other obligations of the Company to the Holders or
the Trustee hereunder or thereunder shall be promptly paid in full or performed,
all in accordance with the terms hereof and thereof; and (b) in case of any
extension of time of payment or renewal of any Notes or any of such other
obligations, that same shall be promptly paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at stated
maturity, by acceleration pursuant to Section 6.02 hereof or otherwise. Failing
payment when due of any amount so guaranteed or any performance so guaranteed
for whatever reason, the Subsidiary Guarantors shall be jointly and severally
obligated to pay the same immediately. Each Subsidiary Guarantor agrees that
this is a guarantee of payment and not a guarantee of collection.

     Each Subsidiary Guarantor hereby agrees that its obligations with regard to
this Subsidiary Guarantee shall be joint and several, unconditional,
irrespective of the validity or enforceability of the Notes or the obligations
of the Company under this Indenture, the absence of any action to enforce the
same, the recovery of any judgment against the Company or any other obligor with
respect to this Indenture, the Notes or the Obligations of the Company under
this Indenture or the Notes, any action to enforce the same or any other
circumstances (other than complete performance) which might otherwise constitute
a legal or equitable discharge or defense of a Subsidiary Guarantor. Each
Subsidiary Guarantor further, to the extent permitted by law, waives and
relinquishes all claims, rights and remedies accorded by applicable law to
guarantors and agrees not to assert or take advantage of any such claims, rights
or remedies, including but not limited to: (a) any right to require any of the
Trustee, the Holders or the Company (each a "Benefited Party"), as a condition
of payment or performance by such Subsidiary Guarantor, to (1) proceed against
the Company, any other guarantor (including any other Subsidiary Guarantor) of
the Obligations under the Subsidiary Guarantees or any other Person, (2) proceed
against or exhaust any security held from the Company, any such other guarantor
or any other Person, (3) proceed against or have resort to any balance of any
deposit account or credit on the books of any Benefited Party in favor of the
Company or any other

                                       61
<PAGE>

Person, or (4) pursue any other remedy in the power of any Benefited Party
whatsoever; (b) any defense arising by reason of the incapacity, lack of
authority or any disability or other defense of the Company including any
defense based on or arising out of the lack of validity or the unenforceability
of the Obligations under the Subsidiary Guarantees or any agreement or
instrument relating thereto or by reason of the cessation of the liability of
the Company from any cause other than payment in full of the Obligations under
the Subsidiary Guarantees; (c) any defense based upon any statute or rule of law
which provides that the obligation of a surety must be neither larger in amount
nor in other respects more burdensome than that of the principal; (d) any
defense based upon any Benefited Party's errors or omissions in the
administration of the Obligations under the Subsidiary Guarantees, except
behavior which amounts to bad faith; (e)(1) any principles or provisions of law,
statutory or otherwise, which are or might be in conflict with the terms of the
Subsidiary Guarantees and any legal or equitable discharge of such Subsidiary
Guarantor's obligations hereunder, (2) the benefit of any statute of limitations
affecting such Subsidiary Guarantor's liability hereunder or the enforcement
hereof, (3) any rights to set-offs, recoupments and counterclaims and (4)
promptness, diligence and any requirement that any Benefited Party protect,
secure, perfect or insure any security interest or lien or any property subject
thereto; (f) notices, demands, presentations, protests, notices of protest,
notices of dishonor and notices of any action or inaction, including acceptance
of the Subsidiary Guarantees, notices of default under the Notes or any
agreement or instrument related thereto, notices of any renewal, extension or
modification of the Obligations under the Subsidiary Guarantees or any agreement
related thereto, and notices of any extension of credit to the Company and any
right to consent to any thereof; (g) to the extent permitted under applicable
law, the benefits of any "One Action" rule and (h) any defenses or benefits that
may be derived from or afforded by law which limit the liability of or exonerate
guarantors or sureties, or which may conflict with the terms of the Subsidiary
Guarantees. Each Subsidiary Guarantor hereby covenants that its Subsidiary
Guarantee shall not be discharged except by complete performance of the
obligations contained in its Subsidiary Guarantee and this Indenture.

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

     Each Subsidiary 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 Subsidiary Guarantor further agrees that, as between the Subsidiary
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 Section 6.02 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
Section 6.02 hereof, such obligations (whether or not due and payable) shall
forthwith become due and payable by the Subsidiary Guarantors for the purpose of
this Subsidiary Guarantee. The Subsidiary Guarantors shall have the right to
seek contribution from any non-paying Subsidiary Guarantor so long as the
exercise of such right does not impair the rights of the Holders under the
Subsidiary Guarantee.

Section 10.02.    Limitation on Subsidiary Guarantor Liability.
                  --------------------------------------------

     Each Subsidiary 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 Subsidiary 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 Subsidiary Guarantors hereby
irrevocably agree that the obligations of such Subsidiary Guarantor under this
Article 10 shall be limited to the maximum amount as shall, after giving effect
to such maximum amount and all other contingent and fixed liabilities of such
Subsidiary Guarantor that are relevant under such laws, including, if
applicable, its guarantee of all obligations under the Credit Agreement, and
after giving effect to any collections from, rights to receive contribution from
or payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under this Article 10, result
in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee
not constituting a fraudulent transfer or conveyance.

Section 10.03.    Execution and Delivery of Subsidiary Guarantee.
                  ----------------------------------------------

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

     Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set
forth in Section 10.01 hereof 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 Subsidiary Guarantors.

Section 10.04.    Subsidiary Guarantors May Consolidate, etc., on Certain Terms.
                  -------------------------------------------------------------

     Except as otherwise provided in Section 10.05 hereof, no Subsidiary
Guarantor may consolidate with or merge with or into (whether or not such
Subsidiary Guarantor is the surviving Person) another Person whether or not
affiliated with such Subsidiary Guarantor unless:

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

     (b)  the Subsidiary Guarantor complies with the requirements of Article 5
hereof.

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

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

Section 10.05.    Releases Following Sale of Assets.
                  ---------------------------------

     In the event of a sale or other disposition of all of the assets of any
Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or
other disposition of all to the capital stock of any Subsidiary Guarantor, in
each case to a Person that is not (either before or after giving effect to such
transactions) a Restricted

<PAGE>

Subsidiary of the Company, then such Subsidiary Guarantor (in the event of a
sale or other disposition, by way of merger, consolidation or otherwise, of all
of the capital stock of such Subsidiary Guarantor) or the corporation acquiring
the property (in the event of a sale or other disposition of all or
substantially all of the assets of such Subsidiary Guarantor) shall be released
and relieved of any obligations under its Subsidiary Guarantee; provided that
the net proceeds of such sale or other disposition are applied in accordance
with the applicable provisions of this Indenture, including without limitation
Section 4.12 hereof. Upon delivery by the Company to the Trustee of an Officers'
Certificate and an Opinion of Counsel to the effect that such sale or other
disposition was made by the Company in accordance with the provisions of this
Indenture, including without limitation Section 4.12 hereof, the Trustee shall
execute any documents reasonably required in order to evidence the release of
any Subsidiary Guarantor from its obligations under its Subsidiary Guarantee.

     Any Subsidiary 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 Subsidiary Guarantor
under this Indenture as provided in this Article 10.

     destroyed Notes that have been replaced or paid and Notes for whose payment
     money has theretofore been deposited in trust and thereafter repaid to the
     Company) have been delivered to the Trustee for cancellation; or

          (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 payable within one
     year and the Company has irrevocably deposited or caused to be deposited
     with the Trustee as trust funds in trust solely for the benefit of the
     Holders, money or U.S. Government Obligations, or a combination thereof, in
     such amounts as will be sufficient without consideration of any
     reinvestment of interest, to pay and discharge the entire indebtedness on
     the Notes not delivered to the Trustee for cancellation for principal,
     premium, if any, and accrued interest and Liquidated Damages, if any, to
     the date of maturity or redemption;

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

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

     (d)  the Company has delivered irrevocable instructions to the Trustee
under this Indenture to apply the deposited money and/or non-callable Government
Securities 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.

effective to waive liabilities under the federal securities laws and it is the

[Insert the Global Note Legend, if applicable pursuant to the terms of the
Indenture]

Indenture]

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

     1.   Interest. Hanger Orthopedic Group, Inc., a Delaware corporation (the
"Issuer"), promises to pay interest on the principal amount of this Note at 10
3/8% per annum until maturity and shall pay Liquidated Damages, if any, as
provided in Section 6(b) of the Registration Rights Agreement. The Issuer shall
pay interest semi-annually on February 15 and August 15 of each year, or if any
such day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes shall accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of issuance; provided, however, 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 the first
of February 15 or August 15 to occur after the date of issuance, unless such
February 15 or August 15 occurs within one calendar month of such date of
issuance, in which case the first Interest Payment Date shall be the second of
February 15 and August 15 to occur after the date of issuance. The Issuer shall
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue principal and premium, if any, from time to time on
demand at a rate that is 1% per annum in excess of the rate then in effect; it
shall pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (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.

     2.   Method of Payment. The Issuer shall pay interest on the Notes (except
defaulted interest) to the Persons who are Holders at the close of business on
the February 1 or August 1 next preceding the Interest Payment Date, even if
such Notes are cancelled after such record date and on or before such Interest
Payment Date, except as provided in Section 2.12 of the Indenture with respect
to defaulted interest. The Notes shall be payable as to principal, premium, if
any, and interest and Liquidated Damages, if any, at the office or agency of the
Issuer maintained for such purpose, or, at the option of the Issuer, payment of
interest may be made by check mailed to the Holders at their addresses set forth
in the Security Register; provided, however, that payment by wire transfer of
immediately available funds shall be required with respect to principal of and
interest and Liquidated Damages, if any,, and premium, if any, on, all Global
Notes and all other Notes the Holders of which shall have provided wire transfer
instructions to the Issuer or the Paying Agent. Such payment shall be in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts.

     3.   Paying Agent and Registrar. Initially, Wilmington Trust Company, the
Trustee under the Indenture, shall act as Paying Agent and Registrar. The Issuer
may change any Paying Agent or Registrar without notice to any Holder. The
Issuer or any of its Subsidiaries may act in any such capacity.

     4.   Indenture. The Issuer issued the Notes under an Indenture dated as of
February 15, 2002 ("Indenture") among the Issuer, the guarantors party thereto
(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 (15 U.S. Code ss.ss. 77aaa-77bbbb). The Notes
are subject to all such terms, and Holders are referred to the Indenture and
such Act for a statement of such terms. 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. The Notes are obligations of the
Issuer unlimited in aggregate principal amount.

     will not be redeemable at the option of the Issuer prior to February 15,
     2006. Starting on that date, the Issuer may redeem all or any portion of
     the Notes, at once or over time, after giving the required notice under the
     Indenture. The Notes may be redeemed at the redemption prices (expressed as
     percentages of principal amount) set forth below, plus accrued and unpaid
     interest and Liquidated Damages, if any, to the redemption date (subject to
     the right of Holders on the relevant record date to receive interest due on
     the relevant interest payment date), if redeemed during the twelve-month
     period commencing on February 15 of the years indicated below:

     Year                                                             Percentage
     ----                                                             ----------
     2006............................................................  105.188%
     2007............................................................  102.594%
     2008 and thereafter.............................................  100.000%

          (b)  At any time and from time to time, prior to February 15, 2005,
     the Issuer may redeem up to 35% of the aggregate principal amount of the
     Notes issued under the Indenture at a redemption price equal to 110.375% of
     the principal amount thereof, plus accrued and unpaid interest and
     Liquidated Damages, if any, to the redemption date (subject to the right of
     Holders on the relevant record date to receive interest due on the relevant
     Interest Payment Date) with the net cash proceeds of any Qualified Equity
     Offering of the Issuer's common stock; provided, however, that after giving
     effect to any such redemption, at least 65% of the aggregate principal
     amount of the Notes issued on the Issue Date remains outstanding. Any such
     redemption shall be made within 90 days of the closing of such Qualified
     Equity Offering upon not less than 30 nor more than 60 days' prior notice.

          (c)  Any prepayment pursuant to this paragraph shall be made pursuant
     to the provisions of Sections 3.01 through 3.06 of the Indenture.

mandatory redemption or sinking fund payments with respect to the Notes.

     7.   Repurchase at Option of Holder.

          (a)  Upon the occurrence of a Change of Control, each Holder shall
     have the right to require the Issuer to repurchase all or any part (equal
     to $1,000 or an integral multiple of $1,000) of such Holder's Notes (a
     "Change of Control Offer") at a purchase price equal to 101% of the
     principal amount thereof, plus accrued and unpaid interest and Liquidated
     Damages, if any, to the purchase date (subject to the right of Holders on
     the relevant record date to receive interest due on the relevant Interest
     Payment Date.

          (b)  If the Issuer or one of its Restricted Subsidiaries consummates
     any Asset Sales, when the aggregate amount of Excess Proceeds exceeds $5
     million, the Issuer shall commence an offer to all Holders of Notes (an
     "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to purchase
     the maximum principal amount of Notes (including any Additional Notes) that
     may be purchased out of the Excess Proceeds at an offer price in cash equal
     to 100% of the principal amount thereof plus accrued and unpaid interest
     and Liquidated Damages thereon, if any, to the date fixed for the closing
     of such offer in accordance with the procedures set forth in the Indenture.
     To the extent that the aggregate amount of Notes (including Additional
     Notes) tendered pursuant to an Asset Sale Offer is less than the Excess
     Proceeds, the Issuer (or such Restricted Subsidiary) may use such
     deficiency for general corporate purposes. If the aggregate principal
     amount of Notes surrendered by Holders thereof exceeds the amount of Excess
     Proceeds, the Trustee shall select the Notes to be purchased on a pro rata
     basis. Holders of Notes that are the subject of an offer to purchase will
     receive an Asset Sale Offer from the Issuer prior to any related purchase
     date and may elect to have such Notes purchased by completing the form
     entitled "Option of Holder to Elect Purchase" on the reverse of the Notes.

     7.   Notice of Redemption. Notice of redemption shall be mailed at least 30
days but not more than 60 days before the redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in

                                      A-4
<PAGE>

denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000, unless all of the Notes held by a Holder are to be
redeemed. On and after the redemption date interest ceases to accrue on Notes or
portions thereof called for redemption.

     8.   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
Issuer may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Issuer need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, the Issuer need
not exchange or register the transfer of any Notes for a period of 15 days
before a selection of Notes to be redeemed or during the period between a record
date and the corresponding Interest Payment Date.

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

     10.  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
voting as a single class, and any existing default or compliance with any
provision of the Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes voting
as a single class. Without the consent of any Holder, the Indenture or the Notes
may be amended or supplemented to cure any ambiguity, omission, defect or
inconsistency, to provide for the assumption by a successor corporation of the
obligations of the Issuer under the Indenture in the case of a merger or
consolidation or sale of all or substantially all of the assets of the Issuer,
provide for uncertificated Notes in addition to or in place of certificated
Notes, to make any change that would provide any additional rights or benefits
to the Holders of Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, or to make any change to comply with any
requirement of the SEC in connection with the qualification of the Indenture
under the TIA.

     11.  Defaults and Remedies. Each of the following is an Event of Default
under the Indenture: (1) default for 30 days in the payment when due of interest
on, or Liquidated Damages with respect to, the Notes; (2) default in payment
when due of principal of, or premium, if any, on the Notes; (3) failure by the
Issuer or any of its Restricted Subsidiaries to comply with Sections 4.09 or
4.10 or Article 5 of the Indenture; (4) failure by the Issuer or any of its
Restricted Subsidiaries for 30 days after notice to comply with Sections 4.12
and 4.18; (5) failure by the Issuer or any of its Restricted Subsidiaries for 60
days after notice to comply with any of its other agreements in the Indenture or
in the Notes; (6) default under any mortgage, indenture or instrument under
which there may be issued or by which there may be secured or evidenced any
Indebtedness for money borrowed by the Issuer or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its
Restricted Subsidiaries) whether such Indebtedness or guarantee now exists, or
is created after the date of the 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"); or (B) results
in the acceleration of such Indebtedness prior to its express maturity; and in
each such case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$10.0 million or more; (7) failure by the Issuer or any of its Subsidiaries to
pay final judgments aggregating in excess of $10.0 million, which judgments are
not paid, discharged or stayed for a period of 30 days; (8) except as permitted
by the Indenture, any Subsidiary Guarantee shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be in
full force and effect or any Subsidiary Guarantor, or any Person acting on
behalf of any Subsidiary Guarantor, shall deny or disaffirm its obligations
under its Subsidiary Guarantee or (9) certain events of bankruptcy or insolvency
described in the Indenture with respect to the Issuer or any of its Restricted
Subsidiaries. If any Event of Default occurs and is continuing, the Trustee or
the Holders of at least 25% in principal amount of the then outstanding Notes
may declare all the Notes to be due and payable. Notwithstanding the foregoing,
in the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Notes shall become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in aggregate principal amount of the then

                                      A-5
<PAGE>

outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing Default 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. 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 on, or the principal
of, the Notes. The Issuer is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Issuer is required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

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

     13.  Designated Senior Debt. The Issuer hereby designates the Notes as
"Designated Senior Debt" as that term is defined in the Senior Subordinated Note
Indenture.

     14.  No Recourse Against Others. No director, officer, employee,
incorporator or stockholder of the Issuer or of any Subsidiary Guarantor, as
such, shall have any liability for any obligations of the Issuer or any
Subsidiary Guarantor under the Indenture, the Notes, the Subsidiary Guarantees
or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such
liability. The waiver and release are part of the consideration for the issuance
of the Notes; such waiver may not be effective to waive liabilities under the
federal securities laws and it is the view of the SEC that such a waiver is
against public policy.

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

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

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

     The Issuer shall furnish to any Holder upon written request and without
charge a copy of the Indenture. Requests may be made to:

     In connection with our proposed purchase of $____________ aggregate
principal amount of:

     (a)  [ ] a beneficial interest in a Global Note, or

     (b)  [ ] a Definitive Note,

          we confirm that:

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

     2.   We understand that the offer and sale of the Notes have not been
registered under the Securities Act, and that the Notes and any interest therein
may not be offered or sold except as permitted in the following sentence. We
agree, on our own behalf and on behalf of any accounts for which we are acting
as hereinafter stated, that if we should sell the Notes or any interest therein,
we will do so only (A) to the Issuer or any subsidiary thereof, (B) in
accordance with Rule 144A under the Securities Act to a "qualified institutional

behalf by a U.S. broker-dealer) to you and to the Issuer a signed letter
substantially in the form of this letter and, if such transfer is in respect of
a principal amount of Notes, at the time of transfer of less than $250,000, an

purchaser that resales thereof are restricted as stated herein.

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

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

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

     You and the Issuer are entitled to rely upon this letter and are
irrevocably authorized to produce this letter or a copy hereof to any interested
party in any administrative or legal proceedings or official inquiry with
respect to the matters covered hereby.

                        EIGHTH SUPPLEMENTAL INDENTURE TO
                        INDENTURE DATED DECEMBER 16, 1997
                            (SENIOR DEBT SECURITIES)

                                  $350,000,000

                          6.125% Senior Notes due 2012

          EIGHTH SUPPLEMENTAL INDENTURE, dated as of February 20, 2002, between
THE ALLSTATE CORPORATION, a Delaware corporation (the "Company"), and STATE
STREET BANK AND TRUST COMPANY, a trust company organized under the laws of the
Commonwealth of Massachusetts, as Trustee (the "Trustee").

                                    RECITALS

          The Company has heretofore executed and delivered to the Trustee an
Indenture for Senior Debt Securities, dated as of December 16, 1997, as amended
by the Third Supplemental Indenture dated as of July 23, 1999 and the Sixth
Supplemental Indenture dated as of June 12, 2000 (the "Indenture"), providing
for the issuance from time to time of series of the Company's Securities.

          Section 301 of the Indenture provides for various matters with respect
to any series of Securities issued under the Indenture to be established in an
indenture supplemental to the Indenture.

          Section 901(7) of the Indenture provides for the Company and the
Trustee to enter into an indenture supplemental to the Indenture to establish
the form or terms of Securities of any series as provided by Sections 201 and
301 of the Indenture.

          NOW, THEREFORE, THIS EIGHTH SUPPLEMENTAL INDENTURE WITNESSETH:

          For and in consideration of the premises and the issuance of the
series of Securities provided for herein, it is mutually agreed, for the equal
and proportionate benefit of all Holders of the Securities of such series, as
follows:

                                   ARTICLE I

                       Relation to Indenture; Definitions

          Section 1.1. RELATION TO INDENTURE. This Eighth Supplemental Indenture
constitutes an integral part of the Indenture.

          Section 1.2. DEFINITIONS. For all purposes of this Eighth Supplemental
Indenture:

                                        1

<PAGE>

          (a) Capitalized terms used herein without definition shall have the
meanings specified in the Indenture;

          (b) All references herein to Articles and Sections, unless otherwise
specified, refer to the corresponding Articles and Sections of this Eighth
Supplemental Indenture; and

          (c) The terms "herein," "hereof," "hereunder" and other words of
similar import refer to this Eighth Supplemental Indenture.

                                   ARTICLE II

                            The Series of Securities

          Section 2.1. TITLE OF THE SECURITIES. There shall be a series of
Securities designated the "6.125% Senior Notes due 2012" (the "Securities").

          Section 2.2. LIMITATION ON AGGREGATE PRINCIPAL AMOUNT. The aggregate
principal amount of the Securities shall initially be limited to $350,000,000.
The Company may, without the consent of the holders of the Securities, issue
additional Securities having the same interest rate, maturity date and other
terms as described in the related prospectus supplement and prospectus. Any
additional Securities, together with the Securities offered by the related
prospectus supplement, will constitute a single series of Securities under the
Indenture. No additional Securities may be issued if an Event of Default under
the Indenture has occurred and is continuing with respect to the Securities.

          Section 2.3. PRINCIPAL PAYMENT DATE. The principal amount of the
Securities outstanding (together with any accrued and unpaid interest) shall be
payable in a single installment on February 15, 2012, which date shall be the
Stated Maturity of the Securities Outstanding.

          Section 2.4. INTEREST AND INTEREST RATES. The rate of interest on each
Security shall be 6.125% per annum, accruing from February 20, 2002, or from the
most recent interest payment date (each such date, an "Interest Payment Date")
to which interest has been paid or duly provided for, payable semiannually in
arrears on February 15 and August 15 of each year commencing August 15, 2002
until the principal thereof shall have become due and payable, and until the
principal thereof is paid or duly provided for or made available for payment.
The amount of interest payable on any Interest Payment Date shall be computed on
the basis of a 360-day year of twelve 30-day months. The amount of interest
payable for any partial period shall be computed on the basis of the actual
number of days elapsed in a 360-day year of twelve 30-day months. In the event
that any date on which interest is payable on any Security is not a Business
Day, then payment of interest payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay). A "Business Day" shall mean any day, other than a
Saturday or Sunday, on which banks in the City of New York and Boston,
Massachusetts are not required by law to close. The interest installment so
payable in respect of any Security, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in the Indenture, be paid to the
person in whose name such Security (or one or more Predecessor Securities) is
registered at the close of business on February 1 or August 1 prior to such
Interest Payment Date. Any such interest installment not punctually paid or duly
provided for in respect of any Security shall forthwith cease to be payable to
the registered Holder on such Regular Record Date and may either be paid to the
Person in whose name such Security (or one or more Predecessor Securities) is
registered at the

                                        2

<PAGE>

close of business on a Special Record Date to be fixed by the Trustee for the
payment of such Defaulted Interest, notice whereof shall be given to the Holders
of this series of Securities not less than 10 days prior to such Special Record
Date, or be paid at any time in any other lawful manner not inconsistent with
the requirements of any securities exchange on which the Securities of this
series may be listed, and upon such notice as may be required by such exchange,
all as more fully provided in the Indenture.

          Section 2.5. PLACE OF PAYMENT. The Place of Payment where the
Securities may be presented or surrendered for payment, where the Securities may
be surrendered for registration of transfer or exchange and where notices and
demand to or upon the Company in respect of the Securities and the Indenture may
be served shall be the Corporate Trust Office of the Trustee.

          Section 2.6. REDEMPTION.

          (a) The Company may redeem the Securities, in whole or in part, at any
time at a redemption price equal to the greater of (i) 100% of the principal
amount of such securities to be redeemed or (ii) an amount, as determined by an
Independent Investment Banker, equal to the sum of the present values of the
remaining scheduled payments of principal of and interest on the securities to
be redeemed (not including any portion of such payments of interest accrued to
the date of redemption) discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate, plus 25 basis points, plus, in either of the above cases, accrued
and unpaid interest thereon to the redemption date.

          (b) For the purposes of this Section 2.6,

          "Adjusted Treasury Rate" means, with respect to any redemption date:

          -    the yield, under the heading which represents the average for the
               immediately preceding week, appearing in the most recently
               published statistical release designated "H.15(519)" published by
               the Board of Governors of the Federal Reserve System (or any
               successor publication which is published weekly by the Board of
               Governors of the Federal Reserve System and which establishes
               yields on actively traded United States Treasury securities
               adjusted to constant maturity) under the caption "Treasury
               Constant Maturities," for the maturity corresponding to the
               Comparable Treasury Issue. If no maturity is within three months
               before or after the Remaining Life, yields for the two published
               maturities most closely corresponding to the Comparable Treasury
               Issue shall be determined and the Adjusted Treasury Rate shall be
               interpolated or extrapolated from such yields on a straight line
               basis, rounding to the nearest month; or

                                        3

<PAGE>

          -    if such release (or any successor release) is not published
               during the week preceding the calculation date or does not
               contain such yields, the rate per annum equal to the semiannual
               equivalent yield to maturity of the Comparable Treasury Issue,
               calculated using a price for the Comparable Treasury Issue
               (expressed as a percentage of its principal amount) equal to the
               Comparable Treasury Price for such redemption date.

          The Adjusted Treasury Rate shall be calculated on the third business
day preceding the redemption date.

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the securities to be redeemed that would be used, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such securities ("Remaining Life").

          "Comparable Treasury Price" means (i) the average of five Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.

          "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by us.

          "Reference Treasury Dealer" means:

          -    each of Lehman Brothers Inc. and Morgan Stanley & Co.
               Incorporated and their respective successors; provided, however,
               that if any of the foregoing shall cease to be a primary U.S.
               Government securities dealer in New York City (a "Primary
               Treasury Dealer"), the Company shall substitute therefor another
               Primary Treasury Dealer; and

          -    any three other Primary Treasury Dealers selected by the Company.

          "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker at 5:00
p.m., New York City Time, on the third business day preceding such redemption
date.

          The Company will mail a notice of redemption at least 30 days but not
more than 60 days before the redemption date to each holder of the securities to
be redeemed. If less than all of the securities are to be redeemed, the trustee
will select, by such method as it will deem fair and appropriate, including pro
rata or by lot, the securities to be redeemed in whole or in part.

                                        4

<PAGE>

          Unless the Company defaults in payment of the redemption price, on and
after the redemption date, interest will cease to accrue on the securities or
portions thereof called for redemption.

          Section 2.7. DENOMINATION. The Securities of this series shall be
issuable only in registered form without coupons and in denominations of $1,000
and integral multiples thereof.

          Section 2.8. CURRENCY. Principal and interest on the Securities shall
be payable in such coin or currency of the United States of America that at the
time of payment is legal tender for payment of public and private debts.

          Section 2.9. FORM OF SECURITIES. The Securities shall be substantially
in the form attached as EXHIBIT A hereto.

          Section 2.10. SECURITIES REGISTRAR AND PAYING AGENT. The Trustee shall
serve initially as Securities Registrar and Paying Agent.

          Section 2.11. SINKING FUND OBLIGATIONS. The Company has no obligation
to redeem or purchase any Securities pursuant to any sinking fund or analogous
requirement or upon the happening of a specified event or at the option of a
Holder thereof.

          Section 2.12. DEFEASANCE AND COVENANT DEFEASANCE. The Company has
elected to have both Section 1302 (relating to defeasance) and Section 1303
(relating to covenant defeasance) applied to the Securities.

          Section 2.13. IMMEDIATELY AVAILABLE FUNDS. All payments of principal
and interest shall be made in immediately available funds.

                                  ARTICLE III

                                    Expenses

          Section 3.1. PAYMENT OF EXPENSES. In connection with the offering,
sale and issuance of the Securities, the Company, in its capacity as borrower
with respect to the Securities, shall pay all costs and expenses relating to the
offering, sale and issuance of the Securities, including commissions to the
underwriters payable pursuant to the Underwriting Agreement, dated February 14,
2002, and compensation and expenses of the Trustee under the Indenture in
accordance with the provisions of Section 607 of the Indenture.

          Section 3.2. PAYMENT UPON RESIGNATION OR REMOVAL. Upon termination of
this Eighth Supplemental Indenture or the Indenture or the removal or
resignation of the Trustee, unless otherwise stated, the Company shall pay to
the Trustee all amounts accrued to the date of such termination, removal or
resignation.

                           (FORM OF FACE OF SECURITY)

          This Security is a Global Security within the meaning of the Indenture
hereinafter referred to and is registered in the name of a Depositary or a
nominee of a Depositary. This Security is exchangeable for Securities registered
in the name of a person other than the Depositary or its nominee only in the

The Depository Trust Company (55 Water Street, New York, New York) to the issuer
or its agent for registration of transfer, exchange or payment, and any Security

                          6.125% Senior Notes due 2012

          THE ALLSTATE CORPORATION, a Delaware corporation (the "Company," which
term includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to CEDE & CO. or registered
assigns, the principal sum of THREE HUNDRED FIFTY MILLION DOLLARS AND NO CENTS
($350,000,000.00) on February 15, 2012. The Company further promises to pay
interest on said principal sum outstanding from February 20, 2002, or from the
most recent interest payment date (each such date, an "Interest Payment Date")
to which interest has been paid or duly provided for, semiannually (subject to
deferral as set forth herein) in arrears on February 15 and August 15 of each
year commencing August 15, 2002 at the rate of 6.125% per annum, until the
principal hereof shall have become due and payable and, until the principal
hereof is paid or duly provided for or made available for payment. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year of twelve 30-day months. The amount of interest payable for any
partial period shall be computed on the basis of the number of actual days
elapsed in a 360-day year of twelve 30-day months. In the event that any date on
which interest is payable on this Security is not a Business Day, then payment
of interest payable on such date will be made on the next succeeding day that is
a Business Day (and without any interest or other payment in respect of any such
delay). A "Business Day" shall mean any day,

                                       A-1

other than a Saturday or Sunday, on which the banks in the City of New York and
Boston, Massachusetts are not required by law to close. The interest installment
so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in the Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on February 1 or August 1 prior to such Interest Payment Date. Any
such interest installment not punctually paid or duly provided for shall
forthwith cease to be payable to the registered Holder on such Regular Record
Date and may either be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record Date to be fixed by the Trustee for the payment of such Defaulted
Interest, notice whereof shall be given to the Holder of this Security not less
than 10 days prior to such Special Record Date, or be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which this Security may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture.

          The principal of (and premium, if any) and the interest on this
Security shall be payable at the office or agency of the Company maintained for
that purpose in the United States in such coin or currency of the United States
of America that at the time of payment is legal tender for payment of public and
private debts; PROVIDED, HOWEVER, that payment of interest may be made at the
option of the Company by check mailed to the registered Holder at such address
as shall appear in the Security Register. Notwithstanding the foregoing, so long
as the Holder of this Security is Cede & Co., the payment of the principal of
(and premium, if any) and interest on this Security will be made at such place
and to such account as may be designated by Cede & Co. All payments of principal
and interest hereunder shall be made in immediately available funds.

          Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

          Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid for any
purpose.

                          (FORM OF REVERSE OF SECURITY)

          This Security is one of a duly authorized issue of securities of the
Company, designated as its 6.125% Senior Notes due 2012 (herein referred to as
the "Securities"), issued under and pursuant to an Indenture, dated as of
December 16, 1997 between the Company and State Street Bank and Trust Company,
as Trustee (herein called the "Trustee," which term includes any successor
trustee under the Indenture), as amended by the Third Supplemental Indenture
dated as of July 23, 1999 and the Sixth Supplemental Indenture dated as of June
12, 2000 and as supplemented by the Eighth Supplemental Indenture, dated as of
February 20, 2002, between the Company and the Trustee (the Indenture as so
amended and supplemented, the "Indenture"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the Holders of the Securities, and of the terms
upon which the Securities are, and are to be, authenticated and delivered.

          All terms used in this Security that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

          The Company may redeem the Securities, in whole or in part, at any
time at a redemption price equal to the greater of (i) 100% of the principal
amount of such securities to be redeemed or (ii) an amount, as determined by an
Independent Investment Banker, the sum of the present values of the remaining
scheduled payments of principal of and interest thereon on the securities to be
redeemed (not including any portion of such payments of interest accrued to the
date of redemption) discounted to the redemption date on a semiannual basis
assuming a 360-day year consisting of twelve 30-day months) at the Adjusted
Treasury Rate, plus 25 basis points, plus, in either of the above cases, accrued
and unpaid interest thereon to the redemption date.

          "Adjusted Treasury Rate" means, with respect to any redemption date:

          -    the yield, under the heading which represents the average for the
               immediately preceding week, appearing in the most recently
               published statistical release designated "H.15(519)" published by
               the Board of Governors of the Federal Reserve System (or any
               successor publication which is published weekly by the Board of
               Governors of the Federal Reserve System and which establishes
               yields on actively traded United States Treasury securities
               adjusted to constant maturity) under the caption "Treasury
               Constant Maturities," for the maturity corresponding to the
               Comparable Treasury Issue. If no maturity is within three months
               before or after the Remaining Life, yields for the two published
               maturities most closely corresponding to the Comparable Treasury
               Issue shall be determined and the Adjusted Treasury Rate shall be
               interpolated or extrapolated from such yields on a straight line
               basis, rounding to the nearest month; or

                                       A-4

<PAGE>

          -    if such release (or any successor release) is not published
               during the week preceding the calculation date or does not
               contain such yields, the rate per annum equal to the semiannual
               equivalent yield to maturity of the Comparable Treasury Issue,
               calculated using a price for the Comparable Treasury Issue
               (expressed as a percentage of its principal amount) equal to the
               Comparable Treasury Price for such redemption date.

          The Adjusted Treasury Rate shall be calculated on the third business
day preceding the redemption date.

          "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the securities to be redeemed that would be used, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of such securities ("Remaining Life").

          "Comparable Treasury Price" means (i) the average of five Reference
Treasury Dealer Quotations for such redemption date, after excluding the highest
and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent
Investment Banker obtains fewer than five such Reference Treasury Dealer
Quotations, the average of all such quotations.

          "Independent Investment Banker" means one of the Reference Treasury
Dealers appointed by us.

          "Reference Treasury Dealer" means:

          -    each of Lehman Brothers Inc. and Morgan Stanley & Co.
               Incorporated and their respective successors; provided, however,
               that if any of the foregoing shall cease to be a primary U.S.
               Government securities dealer in New York City (a "Primary
               Treasury Dealer"), the Company shall substitute therefor another
               Primary Treasury Dealer; and

          -    any three other Primary Treasury Dealers selected by the Company.

          "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any redemption date, the average, as determined by
the Independent Investment Banker, of the bid and asked prices for the
Comparable Treasury Issue (expressed in each case as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker at 5:00
p.m., New York City Time, on the third business day preceding such redemption
date.

          The Company will mail a notice of redemption at least 30 days but not
more than 60 days before the redemption date to each holder of the securities to
be redeemed. If less than all of the securities are to be redeemed, the trustee
will select, by such method as it will deem fair and appropriate, including pro
rata or by lot, the securities to be redeemed in whole or in part.

                                       A-5

<PAGE>

          Unless we default in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the securities or portions
thereof called for redemption.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

          The Indenture contains provisions for satisfaction, discharge and
defeasance at any time of the entire indebtedness of this Security upon
compliance by the Company with certain conditions set forth in the Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities of
each series at the time Outstanding of each series to be affected. The Indenture
also contains provisions permitting Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange therefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security. No
reference herein to the Indenture and no provision of this Security or of the
Indenture (other than Section 1302 and Section 1303 of the Indenture) shall
alter or impair the obligation of the Company to pay the principal and interest
on the Security at the times, place and rate, and in the coin or currency,
herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the
Securities Register, upon surrender of this Security for registration of
transfer at the office or agency of the Company maintained under Section 1002 of
the Indenture duly endorsed by, or accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Securities Registrar, duly
executed by the Holder hereof or his or her attorney duly authorized in writing,
and thereupon one or more new Securities of this series, of authorized
denominations and for the same aggregate principal amount, will be issued to the
designated transferee or transferees. No service charge shall be made for any
such registration of transfer or exchange, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

          Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

                                       A-6
