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

            (b) Global Notes. Notes issued in global form will 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 will 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 will represent such of
      the outstanding Notes as will be specified therein and each shall provide
      that it represents 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 will 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.

                                       30


            (c) Temporary Global Notes. Notes offered and sold in reliance on
      Regulation S shall be issued initially in the form of the Temporary
      Regulation S Global Note, which shall be deposited on behalf of the
      purchasers of the Notes represented thereby with the Trustee, at its New
      York office, as custodian for the Depositary, and registered in the name
      of the Depositary or the nominee of the Depositary for the accounts of the
      designated agents holding on behalf of Euroclear or Clearstream, duly
      executed by the Issuer and authenticated by the Trustee as hereinafter
      provided. Following the termination of the Restricted Period, beneficial
      interests in the Temporary Regulation S Global Note shall be exchanged for
      beneficial interests in the Regulation S Permanent Global Notes pursuant
      to the Applicable Procedures. Simultaneously with the authentication of
      Regulation S Permanent Global Notes, the Trustee shall cancel the
      Temporary Regulation S Global Note. The aggregate principal amount of the
      Temporary Regulation S Global Note and the Regulation S Permanent Global
      Notes may from time to time be increased or decreased by adjustments
      endorsed thereon as specified in Section 2.01(b) in connection with
      transfers of interests as hereinafter provided.

            (d) Euroclear and Clearstream Procedures Applicable. The provisions
      of the "Operating Procedures of the Euroclear System" and "Terms and
      Conditions Governing Use of Euroclear" and the "General Terms and
      Conditions of Clearstream Banking" and "Customer Handbook" of Clearstream
      will be applicable to transfers of beneficial interests the Regulation S
      Global Note that are held by Participants through Euroclear or Clearsteam.

      SECTION 2.02 Execution and Authentication. At least one Officer must sign
the Notes for the Issuer by manual or facsimile signature.

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

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

      The Trustee will, upon receipt of a written order of the Issuer signed by
two Officers (an "Authentication Order"), authenticate Notes for original issue
up to the aggregate principal amount stated on the face of the Notes. Each such
Authentication Order shall specify the number, principal amount and registered
Holder of each of the Notes to be authenticated, whether the Notes are to be
Initial Notes or Additional Notes and whether the Notes are to be issued as
Definitive Notes or Global Notes delivery instructions and such other
information as The Trustee shall reasonably request.

      The Trustee may appoint an authenticating agent acceptable to the Issuer
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 Issuer.

                                       31


      SECTION 2.03 Registrar and Paying Agent. The Issuer will 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 will keep a register of the Notes
and of their transfer and exchange. The Issuer 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 Issuer may change any Paying Agent or Registrar without notice
to any Holder. The Issuer will notify the Trustee in writing of the name and
address of any Agent not a party to this Indenture. If the Issuer fails to
appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. Parent, the Issuer or any of their respective Subsidiaries
may act as Paying Agent or Registrar.

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

      The Issuer 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 Issuer will require
each Paying Agent other than the Trustee to agree in writing that the Paying
Agent will 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 on the Notes, and will notify the Trustee of any default by the Issuer
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 Issuer 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 Parent, the
Issuer or any of their respective Subsidiaries) will have no further liability
for the money. If Parent, the Issuer or any or their respective Subsidiaries
acts as Paying Agent, it will 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 Issuer, the Trustee
will serve as Paying Agent for the Notes.

      SECTION 2.05 Holder Lists. The Trustee will 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 Section 312(a).
If the Trustee is not the Registrar, the Issuer will 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 as the Trustee may reasonably require of the names and addresses of the
Holders of Notes and the Issuer shall otherwise comply with TIA Section 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

                                       32


      successor Depositary. All Global Notes will be exchanged by the Issuer for
      Definitive Notes if:

                  (1) the Issuer 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 Issuer within 120 days after the date of
            such notice from the Depositary; or

                  (2) the Issuer in its sole discretion determines that the
            Global Notes (in whole but not in part) should be exchanged for
            Definitive Notes and delivers a written notice to such effect to the
            Trustee, provided that in no event shall the Temporary Regulation S
            Global Note be exchanged by the Issuer for Definitive Notes prior to
            (x) the expiration of the Restricted Period and (y) the receipt by
            the Registrar of any certificates required pursuant to Rule
            903(b)(3)(ii)(B) under the Securities Act.

            Upon the occurrence of either of the preceding events in (1) or (2)
      above, Definitive Notes shall be issued in such names as the Depositary
      shall instruct the Trustee. Global Notes also may be exchanged or
      replaced, in whole or in part, as provided in Sections 2.07 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), (d) 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 will be effected through the Depositary, in accordance with the
      provisions of this Indenture and the Applicable Procedures. Beneficial
      interests in the Restricted Global Notes will 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 will require compliance with either subparagraph (1) or (2) below, as
      applicable, as well as one or more of the other following subparagraphs,
      as applicable:

                  (1) Transfer of Beneficial Interests in the Same Global Note.
            Beneficial interests in any Restricted Global Note may be
            transferred to Persons who take delivery thereof in the form of a
            beneficial interest in the same Restricted Global Note in accordance
            with the transfer restrictions set forth in the Private Placement
            Legend; provided, however, that prior to the expiration of the
            Restricted Period, transfers of beneficial interests in the
            Temporary 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

                                       33


            orders or instructions shall be required to be delivered to the
            Registrar to effect the transfers described in this Section
            2.06(b)(1).

                  (2) 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)(1)
            above, the transferor of such beneficial interest must deliver to
            the Registrar either:

                        beneficial interest in another Global Note in an amount
                        equal to the beneficial interest to be transferred or
                        exchanged; and

                              (ii) instructions given in accordance with the

                        Depositary to cause to be issued a Definitive Note in an
                        amount equal to the beneficial interest to be
                        transferred or exchanged; and

                              (ii) instructions given by the Depositary to the

                        whose name such Definitive Note shall be registered to
                        effect the transfer or exchange referred to in (1)
                        above, provided that in no event shall Definitive Notes
                        be issued upon the transfer or exchange of beneficial
                        interests in the Temporary Regulation S Global Note

                        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)

            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

            delivery thereof in the form of a beneficial interest in an
            Unrestricted Global Note if the exchange or transfer complies with

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

      If any such transfer is effected pursuant to subparagraph (A) above at a
time when an Unrestricted Global Note has not yet been issued, the Issuer shall
issue and, upon receipt of an Authentication Order in accordance with Section
2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global
Notes in an aggregate principal amount equal to the aggregate principal amount
of beneficial interests transferred pursuant to subparagraph (A) above.

            Rule 903(b)(3)(ii)(B) under the Securities Act, except in the case
            of a transfer pursuant to an exemption from the registration
            requirements of the Securities Act other than Rule 903 or Rule 904.

            interest to a Person who takes delivery thereof in the form of an
            Unrestricted Definitive Note only if the Registrar receives the
            following:

                              (i) if the holder of such beneficial interest in a

                        hereto, including the certifications in item (1)(b)
                        thereof, or

                              (ii) if the holder of such beneficial interest in

                        beneficial interest to a Person who shall take delivery
                        thereof in the form of an Unrestricted Definitive Note,

                        in item (4) thereof,

                  and, in each such case set forth in this subparagraph (A), if
                  the Registrar 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
                  restrictions on transfer contained herein and in the Private
                  Placement Legend are no longer required in order to maintain
                  compliance with the Securities Act.

                  (4) Beneficial Interests in Unrestricted Global Notes to
            Unrestricted Definitive Notes. If any holder of a beneficial
            interest in an Unrestricted Global Note proposes to exchange such
            beneficial interest for a Definitive Note or to transfer such
            beneficial interest to a Person who takes delivery thereof in the
            form of a Definitive Note, then, upon satisfaction of the conditions
            set forth in Section 2.06(b)(2) hereof, the Trustee will cause the
            aggregate principal amount of the applicable Global Note to be
            reduced accordingly pursuant to Section 2.06(h) hereof, and the
            Issuer will execute and the Trustee will authenticate and deliver to
            the Person designated in the instructions a Definitive Note in the
            appropriate principal amount. Any Definitive Note issued in exchange
            for a beneficial interest pursuant to this Section 2.06(c)(3) will
            be registered in such name or names and in such authorized
            denomination or denominations as the holder of such beneficial
            interest requests through instructions to the Registrar from or
            through the Depositary and the Participant or Indirect Participant.
            The Trustee will deliver such Definitive Notes to the Persons in
            whose names such Notes are so registered. Any Definitive Note issued
            in exchange for a beneficial interest pursuant to this Section
            2.06(c)(3) will not bear the Private Placement Legend.

                  (3) Temporary Regulation S Global Note Legend. The Temporary
            Regulation S Global Note will bear a legend in substantially the
            following form:

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

            (g) Cancellation and/or Adjustment of Global Notes. At such time as
      all beneficial interests in a particular Global Note have been exchanged
      for Definitive Notes or a particular Global Note has been redeemed,
      repurchased or canceled in whole and not in part, each such Global Note
      will be returned to or retained and canceled by the Trustee in accordance
      with Section 2.11 hereof. At any time prior to such cancellation, if any

                                       43


      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 will be reduced accordingly and an
      endorsement will 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 will be increased
      accordingly and an endorsement will be made on such Global Note by the
      Trustee or by the Depositary at the direction of the Trustee to reflect
      such increase.

            (h) General Provisions Relating to Transfers and Exchanges.

                  (1) To permit registrations of transfers and exchanges, the
            Issuer will execute and the Trustee will authenticate Global Notes
            and Definitive Notes upon receipt of an Authentication Order in
            accordance with Section 2.02 or at the Registrar's request.

                  (2) No service charge will 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 Issuer may require
            payment of a sum sufficient to cover any transfer tax or similar
            governmental charge payable in connection therewith (other than any
            such transfer taxes or similar governmental charge payable upon
            exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10,
            4.15 and 9.05 hereof).

                  (3) All Global Notes and Definitive Notes issued upon any
            registration of transfer or exchange of Global Notes or Definitive
            Notes will be the valid obligations of the Issuer, 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.

                  (4) Neither the Registrar nor the Issuer will 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
                  selected for redemption in whole or in part, except the
                  unredeemed portion of any Note being redeemed in part; or

                        (C) to register the transfer of or to exchange a Note
                  between a record date and the next succeeding interest payment
                  date.

                  (5) Prior to due presentment for the registration of a
            transfer of any Note, the Trustee, any Agent and the Issuer may deem
            and treat the Person in

                                       44


            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 Issuer shall be affected by notice to the contrary.

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

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

      SECTION 2.07 Replacement Notes. If any mutilated Note is surrendered to
the Trustee or the Issuer and the Trustee receives evidence to its satisfaction
of the destruction, loss or theft of any Note, the Issuer will issue and the
Trustee, upon receipt of an Authentication Order, will authenticate a
replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is
sufficient in the judgment of the Trustee and the Issuer to protect the Issuer,
the Trustee, any Agent and any authenticating agent from any loss, liability or
expense that any of them may suffer if a Note is replaced and subsequently
presented or claimed for payment. The Issuer may charge for its expenses in
replacing a Note.

      Every replacement Note is an additional obligation of the Issuer and will
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. The Notes outstanding at any time are all
the Notes authenticated by the Trustee except for those canceled by it, those
delivered to it for cancellation, those reductions in the interest in a Global
Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 or Sections 2.09, 8.02 or 8.03 as not
outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease
to be outstanding because Parent, the Issuer or an Affiliate of Parent or the
Issuer holds the Note; however, Notes held by Parent, the Issuer or a Subsidiary
of Parent or the Issuer shall not be deemed to be outstanding for purposes of
Section 3.07(a) hereof.

      If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding.

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

      If the Paying Agent (other than Parent, the Issuer, 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 will be deemed to be no longer outstanding and will 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 Parent, the Issuer or any Subsidiary Guarantor, or by
any Person directly or indirectly controlling

                                       45


or controlled by or under direct or indirect common control with Parent, the
Issuer or any Subsidiary Guarantor, will be considered as though not
outstanding, except that for the purposes of determining whether the Trustee
will be protected in relying on any such direction, waiver or consent, only
Notes that a Responsible Officer of the Trustee actually knows are so owned will
be so disregarded.

      SECTION 2.10 Temporary Notes. Until certificates representing Notes are
ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an
Authentication Order, will authenticate temporary Notes. Temporary Notes will be
substantially in the form of certificated Notes but may have variations that the
Issuer considers appropriate for temporary Notes and as may be reasonably
acceptable to the Trustee. Without unreasonable delay, the Issuer will prepare
and the Trustee will authenticate definitive Notes in exchange for temporary
Notes.

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

      SECTION 2.11 Cancellation. The Issuer at any time may deliver Notes to the
Trustee for cancellation. The Registrar and Paying Agent will forward to the
Trustee any Notes surrendered to them for registration of transfer, exchange or
payment. The Trustee and no one else will cancel all Notes surrendered for
registration of transfer, exchange, payment, replacement or cancellation and
will dispose of such canceled Notes (subject to the record retention requirement
of the Exchange Act) in its customary manner. Certification of the destruction
of all canceled Notes will be delivered to the Issuer. The Issuer 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 Issuer defaults in a payment of
interest on the Notes, it will 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 Issuer will 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 Issuer will fix or cause
to be fixed each such special record date and payment date, provided that no
such special record date may 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 Issuer (or, upon the written request of the Issuer, the Trustee in the
name and at the expense of the Issuer) will mail or cause to be mailed to
Holders a notice that states the special record date, the related payment date
and the amount of such interest to be paid.

                                    ARTICLE 3
                            REDEMPTION AND PREPAYMENT

      SECTION 3.01 Notices to Trustee. If the Issuer elects to redeem Notes
pursuant to the optional redemption provisions of Section 3.07 hereof, it must
furnish to the Trustee, at least 30 days but not more than 60 days before a
redemption date, an Officers' Certificate setting forth:

            (1) the clause of this Indenture pursuant to which the redemption
      shall occur,

            (2) the redemption date;

            (3) the principal amount of Notes to be redeemed;

                                       46


            (4) the redemption price; and

            (5) applicable CUSIP numbers.

      SECTION 3.02 Selection of Notes to Be Redeemed or Purchased. If less than
all of the Notes are to be redeemed or purchased in an offer to purchase at any
time, the Trustee will select Notes for redemption or purchase as follows:

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

            (2) if the Notes are not listed on any national securities exchange,
      on a pro rata basis, by lot or by such method as the Trustee deems fair
      and appropriate, subject to the redemption procedures of the Depositary.

      In the event of partial redemption or purchase the particular Notes to be
redeemed or purchased will be selected, unless otherwise provided herein, not
less than 30 nor more than 60 days prior to the redemption or purchase date by
the Trustee from the outstanding Notes not previously called for redemption or
purchase.

      The Trustee will promptly notify the Issuer in writing of the Notes
selected for redemption or purchase and, in the case of any Note selected for
partial redemption or purchase, the principal amount thereof to be redeemed or
purchased. Notes and portions of Notes selected will be in amounts of $1,000 or
whole multiples of $1,000 in excess thereof. No Notes of $1,000 or less shall be
redeemed in part. Except as provided in the preceding sentence, provisions of
this Indenture that apply to Notes called for redemption or purchase also apply
to portions of Notes called for redemption or purchase.

      SECTION 3.03 Notice of Redemption. Subject to the provisions of Section
3.09 hereof, at least 30 days but not more than 60 days before a redemption
date, the Issuer will mail or cause to be mailed, by first class mail, a notice
of redemption to each Holder whose Notes are to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior to
a redemption date if the notice is issued in connection with a defeasance of the
Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8
or 12 of this Indenture.

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

            (1) the redemption date;

            (2) the redemption price;

            (3) 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 will be issued upon
      cancellation of the original Note;

                                       47


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

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

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

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

            (8) 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 Issuer's request, the Trustee will give the notice of redemption in
the Issuer's name and at its expense; provided, however, that the Issuer has
delivered to the Trustee, at least 40 days (unless a shorter time shall be
acceptable to the Trustee) prior to the redemption date, an Officers'
Certificate requesting that the Trustee give such notice and providing a form of
notice setting forth the information to be stated in such notice as provided in
the preceding paragraph.

      SECTION 3.04 Effect of Notice of Redemption. Once notice of redemption is
mailed in accordance with Section 3.03 hereof, Notes called for redemption
become irrevocably due and payable on the redemption date at the redemption
price. Any delayed notice of redemption that is not received at least 30 days
prior to the redemption date shall result in such redemption date becoming
effective 30 days following the date of completed notice. A notice of redemption
may not be conditional.

      SECTION 3.05 Deposit of Redemption or Purchase Price. One Business Day
prior to the redemption or purchase date, the Issuer will deposit with the
Trustee or with the Paying Agent money sufficient to pay the redemption or
purchase price of and accrued interest on all Notes to be redeemed or purchased
on that date. The Trustee or the Paying Agent will promptly return to the Issuer
any money deposited with the Trustee or the Paying Agent by the Issuer in excess
of the amounts necessary to pay the redemption or purchase price of, and accrued
interest on, all Notes to be redeemed or purchased.

      If the Issuer complies with the provisions of the preceding paragraph, on
and after the redemption or purchase date, interest will cease to accrue on the
Notes or the portions of Notes called for redemption or purchase. If a Note is
redeemed or purchased 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 or purchase is
not so paid upon surrender for redemption or purchase because of the failure of
the Issuer to comply with the preceding paragraph, interest shall be paid on the
unpaid principal, from the redemption or purchase 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 or Purchased in Part. Upon surrender of a Note
that is redeemed or purchased in part, the Issuer will issue and, upon receipt
of an Authentication Order,

                                       48


the Trustee will authenticate for the Holder at the expense of the Issuer a new
Note equal in principal amount to the unredeemed or unpurchased portion of the
Note surrendered.

      SECTION 3.07 Optional Redemption. (a) At any time prior to May 15, 2010,
the Issuer may redeem up to 35% of the aggregate principal amount of Notes
issued under this Indenture (including any Additional Notes issued after the
Issue Date) at a redemption price equal to 112.50% of the principal amount
thereof, plus accrued and unpaid interest to, but not including, the redemption
date, with the net cash proceeds of one or more Equity Offerings; provided that:

            (1) at least 65% of the aggregate principal amount of Notes issued
      under this Indenture (including any Additional Notes but excluding Notes
      held by Parent or its Subsidiaries) remains outstanding immediately after
      the occurrence of such redemption; and

            (2) the redemption occurs within 120 days of the date of the closing
      of such Equity Offering.

      Except pursuant to the preceding paragraph, the Notes will not be
redeemable at the Issuer's option prior to May 15, 2012. The Issuer is not,
however, prohibited under this Indenture from acquiring the Notes by means other
than a redemption, whether pursuant to a tender offer, open market purchase or
otherwise so long as the acquisition does not violate the terms of this
Indenture.

      On or after May 15, 2012, the Issuer may redeem all or a part of the Notes
at the redemption prices (expressed as percentages of principal amount) set
forth below plus accrued and unpaid interest on the Notes to be redeemed, to,
but not including, the applicable redemption date, if redeemed during the
twelve-month period beginning on May 15 of the years indicated below, subject to
the rights of Holders on the relevant record date to receive interest on the
relevant interest payment date:



Year                                                                 Percentage
- ----                                                                 ----------
                                                                  
2012.............................................................     106.250%
2013.............................................................     104.167%
2014.............................................................     102.083%
2015 and thereafter..............................................     100.000%


      All redemptions of the Notes will be made upon not less than 30 days' nor
more than 60 days' prior notice mailed by first class mail to each Holder's
registered address as provided in Section 3.03. Unless the Issuer defaults in
the payment of the redemption price, interest will cease to accrue on the Notes
or portions thereof called for redemption on the applicable redemption date.

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

      SECTION 3.08 Mandatory Redemption. The Issuer is not required to make
mandatory redemption or sinking fund payments with respect to the Notes.

                                       49


      SECTION 3.09 Offer to Purchase by Application of Excess Designated
Proceeds or Excess Proceeds. In the event that either (x) pursuant to clause (2)
of the second paragraph of Section 4.10 hereof, the Issuer is required to
commence an offer to all Holders to purchase Notes and, if required by Section
4.10, Pari Passu Indebtedness (a "Designated Asset Sale Offer"), or (y) pursuant
to the fourth paragraph of Section 4.10 hereof, the Issuer is required to
commence an offer to all Holders to purchase Notes and, if required by Section
4.10, Pari Passu Indebtedness (an "Asset Sale Offer"), then, in either such
case, the Issuer will follow the procedures specified below.

      The offer price in any Designated Asset Sale Offer or Asset Sale Offer
will be equal to 100% of the principal amount of the Notes and such Pari Passu
Indebtedness plus accrued and unpaid interest on the Notes and such Pari Passu
Indebtedness to, but excluding, the date of purchase and will be payable in
cash. If any Excess Designated Proceeds remain after consummation of a
Designated Asset Sale Offer or any Excess Proceeds remain after consummation of
an Asset Sale Offer, the Issuer may use those remaining Excess Designated
Proceeds or Excess Proceeds, as applicable, for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes and
Pari Passu Indebtedness tendered into such Designated Asset Sale Offer or such
Asset Sale Offer exceeds the amount of Excess Designated Proceeds or Excess
Proceeds, as applicable, the Notes and such Pari Passu Indebtedness to be
purchased shall be purchased on a pro rata basis based on the principal amount
of Notes and such Pari Passu Indebtedness tendered. In such event, the Issuer
shall furnish to the Trustee an Officers' Certificate setting forth the
principal amount at such time of any such Pari Passu Indebtedness and thereupon
the Trustee shall select the Notes to be purchased as provided in Section 3.02.
Upon completion of each Designated Asset Sale Offer, the amount of Excess
Designated Proceeds will be reset at zero, and upon completion of each Asset
Sale Offer, the amount of Excess Proceeds will be reset at zero.

      The Issuer will comply with the requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with each
repurchase of Notes pursuant to a Designated Asset Sale Offer or an Asset Sale
Offer. To the extent that the provisions of any securities laws or regulations
conflict with the provisions of Sections 3.09 or 4.10 of this Indenture, the
Issuer will comply with the applicable securities laws and regulations and will
not be deemed to have breached its obligations under this Section 3.09 or
Section 4.10 by virtue of such compliance.

      Each Designated Asset Sale Offer and each Asset Sale Offer will remain
open for a period of at least 20 Business Days following its commencement and
not more than 30 Business Days, except to the extent that a longer period is
required by applicable law (the "Offer Period"). No later than three Business
Days after the termination of the Offer Period (the "Purchase Date"), the Issuer
will apply all Excess Designated Proceeds or Excess Proceeds, as applicable (the
"Offer Amount"), to the purchase of Notes and such tendered Pari Passu
Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer
Amount has been tendered, all Notes and Pari Passu Indebtedness tendered in
response to the Designated Asset Sale Offer or the Asset Sale Offer, as
applicable. Payment for any Notes so purchased will be made in the same manner
as interest payments are made.

                                       50


      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, will
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 will be payable to
Holders who tender Notes pursuant to the Designated Asset Sale Offer or the
Asset Sale Offer, as applicable.

      Upon the commencement of a Designated Asset Sale Offer or an Asset Sale
Offer, the Issuer will send, by first class mail, a notice to the Trustee and
each of the Holders. The notice will contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Designated
Asset Sale Offer or the Asset Sale Offer, as applicable. The notice, which will
govern the terms of the Designated Asset Sale Offer or the Asset Sale Offer, as
applicable, will state:

            (1) that the Designated Asset Sale Offer or the Asset Sale Offer, as
      applicable, is being made pursuant to this Section 3.09 and Section 4.10
      hereof and the length of time the Designated Asset Sale Offer or the Asset
      Sale Offer, as applicable, will remain open;

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

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

            (4) that, unless the Issuer defaults in making such payment, any
      Note accepted for payment pursuant to the Designated Asset Sale Offer or
      the Asset Sale Offer, as applicable, will cease to accrue interest after
      the Purchase Date;

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

            (6) that Holders electing to have Notes purchased pursuant to any
      Designated Asset Sale Offer or any Asset Sale Offer, as applicable, will
      be required to surrender the Note, with the form entitled "Option of
      Holder to Elect Purchase" attached to the Notes 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;

            (7) that Holders will 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, telex,
      facsimile transmission or letter setting forth the name of the Holder, the
      principal amount of the Note the Holder delivered for purchase and a
      statement that such Holder is withdrawing his election to have such Note
      purchased;

            (8) that, if the aggregate principal amount of Notes and Pari Passu
      Indebtedness surrendered by holders thereof exceeds the Offer Amount, the
      Issuer will select the Notes and Pari Passu Indebtedness to be purchased
      on a pro rata basis based on the principal amount of Notes and such Pari
      Passu Indebtedness surrendered (with such

                                       51


      adjustments as may be deemed appropriate by the Issuer so that only Notes
      in denominations of $1,000, or integral multiples of $1,000 in excess
      thereof, will be purchased); and

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

      On or before the Purchase Date, the Issuer will, 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 Designated Asset
Sale Offer or the Asset Sale Offer, as applicable, or if less than the Offer
Amount has been tendered, all Notes tendered, and will deliver or cause to be
delivered to the Trustee the Notes properly accepted together with 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, will promptly
(but in any case not later than seven 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 will promptly issue a new Note, and the Trustee, upon written request
from the Issuer will authenticate and mail or deliver (or cause to be
transferred by book entry) 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 will publicly announce the results of the Designated Asset
Sale Offer or the Asset Sale Offer, as applicable, on or as soon as reasonably
practicable after 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
Sections 3.01 through 3.06 hereof.

                                    ARTICLE 4
                                    COVENANTS

      SECTION 4.01 Payment of Notes. The Issuer will pay or cause to be paid the
principal of, premium, if any, and interest on the Notes on the dates and in the
manner provided in the Notes. Principal, premium, if any, and interest will be
considered paid on the date due if the Paying Agent, if other than Parent, the
Issuer or any Subsidiary thereof, holds as of 10:00 a.m. Eastern Time on the due
date money deposited by the Issuer in immediately available funds and designated
for and sufficient to pay all principal, premium, if any, and interest then due.

      The Issuer will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1% per annum in excess of the then applicable interest rate on the Notes to the
extent lawful; it will pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

      SECTION 4.02 Maintenance of Office or Agency. The Issuer will maintain in
the Borough of Manhattan, the City of New York, an office or agency (which may
be an office of the Trustee or an affiliate or an agent of the Trustee,
Registrar or co-registrar) where Notes may

                                       52


be surrendered for registration of transfer or for exchange and where notices
and demands to or upon the Issuer in respect of the Notes and this Indenture may
be served. The Issuer will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Issuer fails to maintain any such required office or agency or fails to
furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee.

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

      The Issuer hereby designates the Corporate Trust Office of the Trustee as
one such office or agency of the Issuer in accordance with Section 2.03 hereof.

      SECTION 4.03 Reports.

            (a) Whether or not required by the rules and regulations of the SEC,
      so long as any Notes are outstanding, Parent and the Issuer will furnish
      to the Holders or cause the Trustee to furnish to the Holders, within the
      time periods specified in the SEC's rules and regulations applicable to a
      registrant that is not an accelerated filer or a large accelerated filer
      (provided, that, with respect to (i) the first quarterly report on Form
      10-Q that would be required to be delivered after the Merger Date, such
      time period for delivery shall be extended to July 1, 2007 and (ii) the
      quarterly report on Form 10-Q for the second quarter of 2007, such time
      period for delivery will be extended to 60 days following the end of such
      fiscal quarter; provided, further, that the Issuer will be obligated to
      deliver, within 45 days following the end of such fiscal quarter, the
      financial information with respect to such fiscal quarter of the same
      type, and in the same presentation, as was furnished as Exhibit 99.1 to
      the Company's Form 8-K filed with the SEC on April 19, 2007):

                  (1) all quarterly and annual reports that would be required to
            be filed with the SEC on Forms 10-Q and 10-K if Parent and the
            Issuer were required to file such reports; and

                  (2) all current reports that would be required to be filed
            with the SEC on Form 8-K if Parent and the Issuer were required to
            file such reports; provided, however, that no such current report
            will be required to be furnished if Parent determines in its good
            faith judgment that such event is not material to the Holders or the
            business, assets, operations, financial positions or prospects of
            Parent, the Issuer and Parent's Restricted Subsidiaries, taken as a
            whole.

            All such reports will be prepared in all material respects in
      accordance with all of the rules and regulations applicable to such
      reports and each annual report on Form 10-K

                                       53


      will include a report on Parent's consolidated financial statements by
      Parent's certified independent accountants; provided, however, that:

                  (i) Sarbanes-Oxley. No certifications or attestations
            concerning internal controls that would otherwise be required
            pursuant to the Sarbanes-Oxley Act of 2002 will be required;

                  (ii) Financial Statements of Acquired Entities. The financial
            statements required of acquired businesses will be limited to the
            financial statements (in whatever form) that Parent receives in
            connection with the acquisition, and whether or not audited;

                  (iii) Financial Statements of Unconsolidated Entities. No
            financial statements of unconsolidated entities will be required;

                  (iv) Supplemental Schedules. The schedules identified in
            Section 5-04 of Regulation S-X under the Securities Act will not be
            required; and

                  (v) Non-GAAP Financial Measures. Compliance with the
            requirements of Item 10(e) of Regulation S-K will not be required.

            If Parent or the Issuer has designated any of their respective
      Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual
      financial information required by the preceding paragraphs will include a
      reasonably detailed presentation, either on the face of the financial
      statements or in the footnotes thereto, and in Management's Discussion and
      Analysis of Financial Condition and Results of Operations, of the
      financial condition and results of operations of Parent, the Issuer and
      Parent's Restricted Subsidiaries separate from the financial condition and
      results of operations of the Unrestricted Subsidiaries of Parent. In
      addition, if any of the Subsidiaries of Parent or the Issuer are
      guaranteeing the Notes, in lieu of financial statements for any such
      Subsidiary Guarantors or the consolidating footnotes as required by Rule
      3-10 of Regulation S-X, Parent may include a reasonably detailed
      presentation, either on the face of the financial statements or in the
      footnotes thereto, or in Management's Discussion and Analysis of Financial
      Condition and Results of Operations, of the financial condition and
      results of operations on a stand-alone basis of Parent, the Issuer, the
      Subsidiary Guarantors and any Subsidiaries that are not Subsidiary
      Guarantors.

            Parent will post the reports specified in the preceding paragraph on
      a website no later than the date Parent is required to provide those
      reports to the Trustee and the Holders and maintain such posting so long
      as any Notes remain outstanding; provided, however, that such website may
      be password protected so long as Parent makes reasonable efforts to notify
      the Trustee and Holders of postings to the website (including through the
      information dissemination procedures of the depositary for the Notes) and
      to provide the Trustee and the Holders with access to such website.

            Delivery of such reports, information and documents to the Trustee
      is for informational purposes only and the Trustee's receipt of such shall
      not constitute constructive notice of any information contained therein or
      determinable from

                                       54


      information contained therein, including Issuer's compliance with any of
      its covenants hereunder (as to which the Trustee is entitled to rely
      exclusively on Officer's Certificates). The Trustee is under no duty to
      examine such reports, information or documents to ensure compliance with
      the provisions of this Indenture or to ascertain the correctness or
      otherwise of information or the statements contained therein. The Trustee
      is entitled to assume such compliance and correctness unless a Responsible
      Officer of the Trustee is informed otherwise.

            (b) In addition, Parent, the Issuer and the Subsidiary Guarantors
      agree that, for so long as any Notes remain outstanding, Parent, the
      Issuer and the Subsidiary Guarantors will furnish to the Holders of Notes
      and to securities analysts and prospective investors, upon their request,
      the information required to be delivered pursuant to Rule 144A(d)(4) under
      the Securities Act.

            (c) Except with respect to receipt of Note payments when due and any
      Default or Event of Default information contained in the Officer's
      Certificate delivered to it pursuant to this Section 4.03, the Trustee
      shall have no duty to review, ascertain or confirm the Issuer's compliance
      with, or the breach of any representation, warranty of covenant made in
      this Indenture.

      SECTION 4.04 Compliance Certificate.

            (a) Parent, the Issuer and each Subsidiary Guarantor (to the extent
      that such Subsidiary Guarantor is so required under the TIA) shall deliver
      to the Trustee, within 90 days after the end of each fiscal year, an
      Officers' Certificate stating that a review of the activities of Parent,
      the Issuer and their respective Subsidiaries during the preceding fiscal
      year has been made under the supervision of the signing Officers with a
      view to determining whether Parent, the Issuer and each Subsidiary
      Guarantor has kept, observed, performed and fulfilled its obligations
      under this Indenture, and further stating, as to each such Officer signing
      such certificate, that to the best of his or her knowledge Parent, the
      Issuer and each Subsidiary Guarantor has kept, observed, performed and
      fulfilled each and every covenant contained in this Indenture and is not
      in default in the performance or observance of any of the terms,
      provisions and conditions of this Indenture (or, if a Default or Event of
      Default has occurred, describing all such Defaults or Events of Default of
      which he or she may have knowledge and what action the Issuer is taking or
      proposes to take with respect thereto).

            (b) So long as any of the Notes are outstanding, the Issuer will
      deliver to the Trustee, forthwith upon any Officer becoming aware of any
      Default or Event of Default that has not been cured, an Officers'
      Certificate specifying such Default or Event of Default and what action
      the Issuer is taking or proposes to take with respect thereto.

      SECTION 4.05 Taxes. Parent and the Issuer will pay, and will cause each of
their respective Subsidiaries to pay, prior to delinquency, all material taxes,
assessments, and governmental levies except such as are contested in good faith
and by appropriate proceedings or where the failure to effect such payment is
not adverse in any material respect to the Holders of the Notes.

                                       55


      SECTION 4.06 Stay, Extension and Usury Laws. Parent, the Issuer and each
of the Subsidiary Guarantors covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay, extension or usury law
wherever enacted, now or at any time hereafter in force, that may affect the
covenants or the performance of this Indenture; and Parent, the Issuer and each
of the Subsidiary Guarantors (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not, by resort to any such law, hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law has been enacted.

      SECTION 4.07 Restricted Payments.

            (a) Parent and the Issuer will not, and will not permit any of
      Parent's Restricted Subsidiaries to, directly or indirectly:

                  (1) declare or pay any dividend or make any other payment or
            distribution on account of Parent's, the Issuer's or any of Parent's
            Restricted Subsidiaries' Equity Interests or to the direct or
            indirect holders of Parent's, the Issuer's or any of Parent's
            Restricted Subsidiaries' Equity Interests in their capacity as such
            (other than dividends or distributions payable in Equity Interests
            (other than Disqualified Stock) of Parent and other than dividends
            or distributions payable to Parent, the Issuer or any of Parent's
            Restricted Subsidiaries);

                  (2) purchase, redeem or otherwise acquire or retire for value
            any Equity Interests of Parent, the Issuer or any of Parent's
            Restricted Subsidiaries (other than any Equity Interests owned by
            Parent, the Issuer or any of Parent's Restricted Subsidiaries);

                  (3) make any payment on or with respect to, or purchase,
            redeem, defease or otherwise acquire or retire for value, any
            Indebtedness of Parent, the Issuer or any Subsidiary Guarantor that
            is contractually subordinated to the Notes or to any Note Guarantee
            (excluding any intercompany Indebtedness between or among Parent,
            the Issuer and any of Parent's Restricted Subsidiaries), except a
            payment of interest or principal at the Stated Maturity thereof; or

                  (4) make any Restricted Investment;

      (all such payments and other actions set forth in these clauses (1)
      through (4) above being collectively referred to as "Restricted
      Payments"), unless, at the time of and after giving effect to such
      Restricted Payment:

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

                  (B) the Issuer would, after giving pro forma effect to such
            Restricted Payment 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

                                       56


            additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
            test set forth in Section 4.09(a) hereof; and

                  (C) such Restricted Payment, together with the aggregate
            amount of all other Restricted Payments made by Parent, the Issuer
            and Parent's Restricted Subsidiaries since the Issue Date (excluding
            Restricted Payments permitted by clauses (2), (3), (5), (6), (7),
            (9) and (12), of the next succeeding paragraph), is less than the
            sum, without duplication, of:

                        (i) 50% of the Consolidated Net Income of Parent during
                  the period (taken as one accounting period) from the Merger
                  Date to the end of Parent'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) provided, that, with respect to the period commencing
                  on the Merger Date until the last day of the fiscal quarter in
                  which the Merger Date shall occur, the Consolidated Net Income
                  of Parent shall be deemed to equal the product of (x) the
                  Consolidated Net Income of Parent for the entire fiscal
                  quarter in which the Merger Date shall occur, times (y) a
                  fraction, (A) the numerator of which equals the number days in
                  the period commencing on, but excluding, the Merger Date and
                  ending on, and including, the last day of such fiscal quarter,
                  and (B) the denominator of which equals the total number of
                  days in such fiscal quarter; plus

                        (ii) 100% of the aggregate net cash proceeds received by
                  Parent subsequent to the Merger Date (x) as a contribution to
                  its common equity capital or (y) from the issue or sale of
                  Equity Interests of Parent (other than Disqualified Stock or
                  any other Equity Interest issued to an employee stock
                  ownership plan or to a trust established by Parent or any of
                  its Subsidiaries for the benefit of their employees) or from
                  the issue or sale of convertible or exchangeable Disqualified
                  Stock or convertible or exchangeable debt securities 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 Parent or issued to an
                  employee stock ownership plan or to a trust established by
                  Parent or any of its Subsidiaries for the benefit of their
                  employees; plus

                        (iii) to the extent that any Restricted Investment that
                  was made subsequent to the Merger Date is sold for cash or
                  otherwise liquidated or repaid for cash, the lesser of (i) the
                  cash received as return of capital with respect to such
                  Restricted Investment (less the cost of disposition if any)
                  and (ii) the amount of such Restricted Investment as of
                  immediately prior to such sale as defined pursuant to the last
                  sentence of the definition of "Investment;" plus

                        (iv) to the extent that any Unrestricted Subsidiary of
                  Parent designated as such after the Merger Date is
                  redesignated as a Restricted

                                       57


                  Subsidiary after the Merger Date, 100% of the Fair Market
                  Value of Parent's Investment in such Subsidiary as of the date
                  of such redesignation.

            (b) So long as (solely in the case of clauses (4), (8), (10) and
      (12)) no Default has occurred and is continuing or would be caused
      thereby, the preceding provisions will not prohibit:

                  (1) the payment of any dividend or distribution or the
            consummation of any irrevocable redemption within 60 days after the
            date of declaration of the dividend or distribution or giving of the
            redemption notice, as the case may be, if, at the date of
            declaration or notice, the dividend, distribution or redemption
            payment would have complied with the provisions of this Indenture;

                  (2) the making of any Restricted Payment in exchange for, or
            out of the net cash proceeds received by Parent of the substantially
            concurrent sale (other than to a Subsidiary of Parent) of, Equity
            Interests of Parent (other than Disqualified Stock or any other
            Equity Interest issued to an employee stock ownership plan or to a
            trust established by Parent or any of its Subsidiaries for the
            benefit of their employees) or from the substantially concurrent
            cash capital contribution received by Parent from its stockholders;
            provided that the amount of any such net cash proceeds that are
            utilized for any such Restricted Payment will be excluded from
            Section 4.07(a)(C)(ii);

                  (3) the repurchase, redemption, defeasance or other
            acquisition or retirement for value of Indebtedness of Parent, the
            Issuer or any Subsidiary Guarantor that is contractually
            subordinated to the Notes or to any Note Guarantee with the net cash
            proceeds from a substantially concurrent incurrence of, or in
            exchange for, Permitted Refinancing Indebtedness that is
            contractually subordinated to the Notes and the Note Guarantee as to
            the same extent as the Indebtedness being refinanced;

                  (4) the repurchase, redemption or other acquisition or
            retirement for value of any Equity Interests of Parent, the Issuer
            or any Restricted Subsidiary of Parent held by any current or former
            officer, director, consultant or employee of Parent, the Issuer or
            any Restricted Subsidiary of Parent pursuant to any equity
            subscription agreement, stock option agreement, shareholders' or
            members' agreement or similar agreement, plan or arrangement;
            provided that (x) the aggregate price paid for all such repurchased,
            redeemed, acquired or retired Equity Interests may not exceed $5.0
            million in any calendar year (provided, however, that Parent, the

            repurchases, redemptions or other acquisitions or retirements for
            value permitted to have been made, but not made, in the immediately
            preceding calendar year), and (y) the aggregate price paid for all
            such repurchased, redeemed, acquired or retired

                                       58

            million in the aggregate;

                  (5) the repurchase of Equity Interests deemed to occur upon
            the exercise of stock options to the extent such Equity Interests

            limited liability company, any similar distribution) by a Restricted
            Subsidiary of Parent to the holders of its Equity Interests on a pro
            rata basis;

                  (7) so long as Parent is treated as an S Corporation as
            defined under Section 1361(a)(1) of the Code and to the extent its
            Subsidiaries (other than any Foreign Subsidiaries) are treated as
            Qualified Subchapter S Subsidiaries as defined under Section
            1361(b)(3)(b) of the Code or otherwise disregarded as separate from
            Parent for U.S. federal income tax purposes ("Disregarded
            Subsidiaries"), dividends or other distributions by Parent to the
            holders of Parent's Equity Interests in an aggregate amount in any
            calendar year equal to 39% of Parent's taxable income in respect of
            such calendar year assuming for purposes of this calculation that
            (i) Parent is a C corporation, (ii) Parent's only Subsidiaries are
            Disregarded Subsidiaries, and (iii) the taxable income of Parent is

            with the Fixed Charge Coverage Ratio test set forth in Section
            4.09(a);

                  (9) Restricted Payments to the holders of Equity Interests in

            in the Offering Memorandum;

                  (10) to the extent that any holder of Parent's Equity
            Interests is a obligor under the Shareholder Loan and so long as
            there shall exist no default under Section 8.1.7 of the Shareholder
            Loan Agreement, dividends or other distributions by Parent to such
            holder of Parent's Equity Interests in an amount equal to the actual
            cash amount of interest due and payable by such holder of Parent's
            Equity Interests under the Shareholder Loan, without regard to any
            "gross-up" or similar amounts in respect of taxes, if any, on any
            such dividend or distribution, provided that the proceeds of any
            such dividend or distribution is immediately applied by such holder
            of Parent's Equity Interests to the payment of such interest in
            respect to the Shareholder Loan;

                  (11) the purchase of fractional shares upon conversion of any
            securities of Parent or the Issuer into, or the exercise of rights
            with respect to, Equity Interests of Parent or the Issuer provided
            that the such fractional shares or the

                                       59


            right to receive such fractional shares shall have not been created
            for the purpose of circumventing the provisions of this Section
            4.07; and

                  (12) other Restricted Payments in an aggregate amount not to
            exceed $25 million since the Issue Date.

      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 Parent, the Issuer or such Restricted
Subsidiary, as the case may be, pursuant to the Restricted Payment. The Fair
Market Value of any assets or securities that are required to be valued by this
Section 4.07 will be determined by the Board of Directors of the Issuer whose
resolution 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 $15 million. For purposes of determining compliance
with this Section 4.07, if a Restricted Payment meets the criteria of more than
one of the exceptions described in clauses (1) through (12) above or is entitled
to be made according to the first paragraph of this Section 4.07, the Issuer
may, in its sole discretion, classify the Restricted Payment in any manner that
complies with this Section 4.07.

      SECTION 4.08 Dividend and Other Payment Restrictions Affecting
Subsidiaries.

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

                  (1) pay dividends or make any other distributions on its
            Capital Stock to Parent, the Issuer or any of Parent's Restricted
            Subsidiaries, or with respect to any other interest or participation
            in, or measured by, its profits, or pay any Indebtedness owed to
            Parent, the Issuer or any of Parent's Restricted Subsidiaries;

                  (2) make loans or advances to Parent, the Issuer or any of
            Parent's Restricted Subsidiaries; or

            Agreement and Credit Facilities as in effect on the Merger Date and
            any amendments, restatements, modifications, supplements, renewals,
            refundings, replacements or refinancings of those agreements;
            provided that such amendments, restatements, modifications,
            supplements, renewals, refundings, replacements 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

                                       60


            Merger Date (as determined in good faith by the Board of Directors
            of Parent or the Issuer);

            or such agreement was entered into 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;

            ordinary course of business and Capital Lease Obligations that
            impose restrictions on the property purchased or leased of the
            nature described in Section 4.08(a)(3);

                  (7) any agreement for the sale or other disposition of a
            Restricted Subsidiary of Parent that restricts distributions, loans
            or transfers by that Restricted Subsidiary pending closing of the
            sale or other disposition;

                  (8) 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, with respect to such encumbrance or restriction set
            forth in clauses (1), (2) or (3) of Section 4.08(a) than those
            contained in the agreements governing the Indebtedness being
            extended, renewed, refunded, refinanced, replaced, defeased or
            discharged (as determined in good faith by the Board of Directors of
            Parent or the Issuer);

                  (9) Liens permitted to be incurred under Section 4.12 that
            limit the right of the debtor to dispose of the assets securing such
            Indebtedness;

                  (10) provisions limiting the disposition or distribution of
            assets or property or transfer of Capital Stock in joint venture
            agreements, asset sale agreements, sale-leaseback agreements, stock
            sale agreements and other similar agreements entered into (a) in the
            ordinary course of business or (b) with the approval of the Issuer's
            Board of Directors, which limitation is applicable only to the asset
            or property that are the subject of such agreements;

                                       61

            as a whole, with respect to encumbrances or restrictions set forth
            in clauses (1), (2) or (3) of Section 4.08(a) than such encumbrances
            and restrictions prior to such amendment or refinancing (as
            determined in good faith by the Board of Directors of Parent or the
            Issuer).

            (a) Parent and the Issuer will not, and will not permit any of
      Parent's Restricted Subsidiaries to, directly or indirectly, create,
      incur, issue, assume, guarantee or otherwise become directly or indirectly
      liable, contingently or otherwise, with respect to (collectively, "incur")
      any Indebtedness (including Acquired Debt), and Parent and the Issuer will
      not issue any Disqualified Stock and will not permit the Issuer or any of
      Parent's Restricted Subsidiaries to issue any Disqualified Stock or any
      shares of preferred equity; provided, however, that Parent, the Issuer and
      any of Parent's Restricted Subsidiaries may incur Indebtedness (including
      Acquired Debt) or issue Disqualified Stock and the Issuer and any of
      Parent's Restricted Subsidiaries may issue preferred equity, if, on the
      date of such incurrence or issuance, the Fixed Charge Coverage Ratio for
      Parent's most recently ended four full fiscal quarters for which internal
      financial statements are available immediately preceding the date on which
      such additional Indebtedness is incurred or such Disqualified Stock or
      such preferred equity is issued, as the case may be, would have been at
      least (A) 1.75 to 1.00 if such Indebtedness is incurred or such
      Disqualified Stock or such preferred equity is issued on or prior to June
      30, 2008 or (B) 2.00 to 1.00 if such Indebtedness is incurred or such
      Disqualified Stock or such preferred equity is issued after June 30, 2008,
      in each case, determined on a pro forma basis (including a pro forma
      application of the net proceeds therefrom), as if the additional
      Indebtedness had been incurred or the Disqualified Stock or the preferred
      equity had been issued, as the case may be, at the beginning of such
      four-quarter period.

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

            aggregate principal amount at any one time outstanding under this
            clause (1) (with letters of credit being deemed to have a principal
            amount equal to the maximum potential liability of Parent, the
            Issuer and such Restricted Subsidiaries thereunder) not to exceed
            $2,170 million less the aggregate amount of all Net Proceeds of
            Asset Sales applied by Parent, the Issuer or any of Parent's

            (excluding any Additional Notes or any additional Floating Rate
            Notes issued after the Issue Date) and the related Note Guarantees
            or Floating Rate Note Guarantees;

                  (3) the incurrence by Parent, the Issuer and Parent's

            all or any part of the purchase price or cost of design,
            development, construction, installation or improvement of property
            (real or personal), plant or equipment used in the ordinary course
            of business of Parent, the Issuer or any of Parent's Restricted

            Subsidiaries; provided, however, that:

                        (a) if Parent, the Issuer or any Subsidiary Guarantor is
                  the obligor on such Indebtedness and the payee is not Parent,

                                       63


                  Subsidiary Guarantor, such Indebtedness is expressly
                  subordinated in right of payment to the prior payment in full
                  in cash of all Obligations then due with respect to the Notes,
                  in the case of the Issuer, or the Note Guarantee, in the case
                  of Parent or a Subsidiary Guarantor; and

                  Interests that results in any such Indebtedness being held by
                  a Person other than Parent, the Issuer or a Restricted

                  the Issuer or a Restricted Subsidiary of Parent, shall be
                  deemed, in each case, to constitute an incurrence of such
                  Indebtedness by Parent, the Issuer or such Restricted
                  Subsidiary, as the case may be, that was not permitted by this

            however, that:

                        (a) any subsequent issuance or transfer of Equity
                  Interests that results in any such preferred equity being held

                  Restricted Subsidiary of Parent,

            shall be deemed, in each case, to constitute an issuance of such

            Restricted Subsidiary that was not permitted by this clause (7);

                  (8) the incurrence by Parent, the Issuer or any of Parent's

            another provision of this Section 4.09 (including Section 4.09(a));
            provided that (A) if the Indebtedness being guaranteed is
            subordinated in right of payment to the Notes or the Note
            Guarantees, as applicable, then the guarantee thereof shall be
            subordinated in right of payment to the Notes or the Note Guarantee,

            thereof shall be pari passu in right of payment to the Notes or the
            Note Guarantee, as applicable, to the same extent as the
            Indebtedness so guaranteed, provided, further, that any Restricted
            Subsidiary of Parent that guarantees other Indebtedness pursuant to
            this clause (9) shall concurrently

                                       64

            a bank or other financial institution of a check, draft or similar
            instrument inadvertently drawn against insufficient funds so long as

                  (12) Indebtedness, Disqualified Stock or preferred equity of
            any Person that is acquired by the Issuer, the Issuer or any of

            provided, however, that such Indebtedness, Disqualified Stock or
            preferred equity is not incurred or issued in contemplation of such
            acquisition or merger or to provide all or a portion of the funds or

            permitted by this clause (14);

                  (15) the incurrence by Parent, the Issuer or any of Parent's

            when taken together with all other Capital Lease Obligations of
            Parent, the Issuer and Parent's Restricted Subsidiaries incurred
            pursuant to this clause (15) and outstanding on the date of such

            not a Receivables Subsidiary (except for Standard Securitization
            Undertakings), provided that such Qualified Receivables Transaction
            shall be deemed an Asset Sale under this Indenture and Parent, the
            Issuer or the applicable Restricted Subsidiary applies the proceeds
            of such transaction in compliance with Section 4.10;

                  (17) Indebtedness with respect to a Motor Vehicle Financing,
            provided, that such Motor Vehicle Financing shall be deemed an Asset
            Sale under this Indenture and Parent, the Issuer or the applicable
            Restricted Subsidiary applies the proceeds of such transaction in

            Indebtedness incurred to extend, renew, refund, refinance, replace,
            defease or discharge any Indebtedness incurred pursuant to this
            clause (18), not to exceed $60 million.

            (c) For purposes of determining compliance with this Section 4.09,
      in the event that an item of proposed Indebtedness, Disqualified Stock or
      preferred equity meets the criteria of more than one of the categories of
      Permitted Debt described in clauses (1) through (18) of Section 4.09(b),
      or is entitled to be incurred pursuant to Section 4.09(a), the Issuer will
      be permitted to classify such item of Indebtedness, Disqualified Stock or
      preferred equity on the date of its incurrence and will only be required
      to include the amount and type of such Indebtedness, Disqualified Stock or
      preferred equity in one of clauses (1) through (18) of Section 4.09(b) or
      as having been incurred pursuant to Section 4.09(a), although the Issuer
      may divide and classify an item of Indebtedness, Disqualified Stock or
      preferred equity in one or more of the categories of Permitted Debt
      described in such clauses or as having been incurred pursuant to Section
      4.09(a) and may later reclassify all or a portion of such item of
      Indebtedness, Disqualified Stock or preferred equity, in any manner that
      complies with this Section 4.09. Indebtedness under Credit Facilities
      outstanding on the Merger Date will be deemed to have been incurred on
      such date in reliance on the exception provided by clause (1) of the
      definition of "Permitted Debt". The accrual of interest or dividends, the
      accretion of accreted value or amortization of original issue discount,
      the payment of interest on any Indebtedness in the form of additional
      Indebtedness with the same terms, the reclassification of preferred equity
      as Indebtedness due to a change in accounting principles, and the payment
      of dividends on Disqualified Stock or preferred equity in the form of
      additional shares of the same class of Disqualified Stock or preferred
      equity will not be deemed to be an incurrence of Indebtedness or an
      issuance of Disqualified Stock or preferred equity for

                                       66


      purposes of this Section 4.09; provided, in each such case (other than
      preferred stock that is not Disqualified Stock), that the amount of any
      such accrual, accretion or amortization or payment (without duplication)
      is included in Fixed Charges of Parent, the Issuer and Parent's Restricted
      Subsidiaries as accrued, accreted or amortized or paid. Notwithstanding
      any other provision of this Section 4.09, the maximum amount of
      Indebtedness that Parent, the Issuer or any Restricted Subsidiary may
      incur pursuant to this Section 4.09 shall not be deemed to be exceeded
      solely as a result of fluctuations in exchange rates or currency values.

      SECTION 4.10 Asset Sales. Parent and the Issuer will not, and will not
permit any of Parent's Restricted Subsidiaries to, consummate an Asset Sale
unless:

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

            (2) at least 75% of the consideration received in the Asset Sale by
      Parent, the Issuer or such Restricted Subsidiary is in the form of cash or
      Cash Equivalents or Marketable Securities. For purposes of this provision,
      each of the following will be deemed to be cash:

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

                  (B) any securities, notes or other obligations received by
            Parent, the Issuer or any such Restricted Subsidiary from such
            transferee that are converted by Parent, the Issuer or such
            Restricted Subsidiary into cash or Cash Equivalents within 120 days
            of the receipt thereof, to the extent of the cash or Cash
            Equivalents received in that conversion; or

                  (C) any Capital Stock or assets of the kind referred to in
            clause (2) or (4) of the second following paragraph of this Section
            4.10.

      In the event of an Asset Sale consisting of (x) any sale and leaseback
transaction, (y) any Qualified Receivables Transaction or (z) any Motor Vehicle
Financing (each, a "Designated Asset Sale"), the Net Proceeds from such
Designated Asset Sale shall be applied as follows:

            (1) to, within five Business Days of the receipt of such Net
      Proceeds, repay all outstanding First Priority Lien Obligations and, if
      such First Priority Lien Obligations is revolving credit Indebtedness, to
      correspondingly reduce commitments with respect thereto; and

            (2) in the event that any Net Proceeds from any Designated Asset
      Sale remain after the repayment in full of all First Priority Lien
      Obligations pursuant to the

                                       67


      immediately preceding clause (1) (such remaining Net Proceeds are herein
      referred to as "Excess Designated Proceeds"), within 30 days after the
      Designated Asset Sale giving rise to such Excess Designated Proceeds, the
      Issuer will, in accordance with the provisions of Section 3.09, make a
      Designated Asset Sale Offer to all Holders and all holders of Pari Passu
      Indebtedness containing provisions similar to those set forth in this
      Section 4.10 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 Pari Passu Indebtedness that may be purchased out of the
      Excess Designated Proceeds.

      Unless otherwise provided in the preceding paragraph, within 365 days
after the receipt of any Net Proceeds from an Asset Sale, the Issuer (or the
applicable Restricted Subsidiary, as the case may be), may apply such Net
Proceeds, at its option:

            (1) to repay First Priority Lien Obligations and, if such First
      Priority Lien Obligations is revolving credit Indebtedness, to
      correspondingly reduce commitments with respect thereto;

            (2) to acquire all or substantially all of the assets of, or any
      Capital Stock of, another Permitted Business; provided, that in the case
      of any such acquisition of Capital Stock, the Permitted Business is or
      becomes a Restricted Subsidiary of Parent;

            (3) to make a capital expenditure; or

            (4) to acquire other assets that are not classified as current
      assets under GAAP and that are used or useful in a Permitted Business.

      Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $10 million, within 30 days thereof,
the Issuer will, in accordance with the provisions of Section 3.09, make an
Asset Sale Offer to all Holders and all holders of Pari Passu Indebtedness
containing provisions similar to those set forth in this Section 4.10 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 Pari Passu Indebtedness
that may be purchased out of the Excess Proceeds.

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

      SECTION 4.11 Transactions with Affiliates.

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

                                       68


                  (1) the Affiliate Transaction is on terms that are not
            materially less favorable to Parent, the Issuer or the relevant
            Restricted Subsidiary (as determined by in good faith by the Board
            of Directors of Parent or the Issuer) than those that would have
            been obtained in a comparable transaction by Parent, the Issuer or
            such Restricted Subsidiary with an unrelated Person; and

                  (2) the Issuer delivers to the Trustee:

                        (A) with respect to any Affiliate Transaction or series
                  of related Affiliate Transactions involving aggregate
                  consideration in excess of $5 million, a resolution of the
                  Board of Directors of the Issuer set forth in an Officers'
                  Certificate certifying that such Affiliate Transaction
                  complies with clause (1) of this Section 4.11(a) and that such
                  Affiliate Transaction has been approved by a majority
                  (including a majority of the disinterested members, if any),
                  of the Board of Directors of the Issuer; and

                        (B) with respect to any Affiliate Transaction or series
                  of related Affiliate Transactions involving aggregate
                  consideration in excess of $15 million, an opinion as to the
                  fairness to Parent, the Issuer or such Restricted Subsidiary
                  of such Affiliate Transaction from a financial point of view
                  issued by an accounting, appraisal or investment banking firm
                  of national standing.

            (b) The following items will not be deemed to be Affiliate
      Transactions and, therefore, will not be subject to the provisions of
      Section 4.11(a):

            plan, officer or director indemnification agreement or any similar
            arrangement entered into by Parent, the Issuer or any of Parent's
            Restricted Subsidiaries in the ordinary course of business and
            payments pursuant thereto;

            Subsidiary) that is an Affiliate of Parent, the Issuer or a
            Restricted Subsidiary of Parent solely because Parent, the Issuer or
            such Restricted Subsidiary owns an Equity Interest in, or controls,
            such Person;

                  (4) payment of reasonable fees to, and indemnity provided on

            the Merger Date and described in the Offering Memorandum and any
            amendment, modification or replacement of such agreement (so long as
            such amendment or replacement is not less favorable to Parent, the
            Issuer, any Restricted Subsidiary of Parent or the Holders, taken as
            a whole, than the original agreement as in effect on the Merger Date
            as determined in good faith by the Board of Directors of Parent or
            the Issuer);

                  (8) any agreement between any Person and an Affiliate of such
            Person existing at the time such Person is acquired by or merged
            into Parent, the Issuer or any of Parent's Restricted Subsidiaries;
            provided, that such agreement was not entered into contemplation of
            such acquisition or merger, or any amendment thereto (so long as any
            such amendment is not disadvantageous to the Holders of the Notes
            when taken as a whole as compared to the applicable agreement as in
            effect on the date of such acquisition or merger); and

                  (9) any Qualified Receivables Transaction.

      SECTION 4.12 Liens. Parent and the Issuer will not and will not permit any
of Parent's Restricted Subsidiaries to create, incur, assume or otherwise cause
or suffer to exist or become effective (i) any Lien of any kind (other than
Permitted Liens) on any asset or property of Parent, the Issuer or any of
Parent's Restricted Subsidiaries securing Indebtedness (other than First
Priority Lien Obligations) unless the Notes are equally and ratably secured with
(or on a senior basis to, in the case of obligations subordinated in right of
payment to the Notes) the obligations so secured until such time as such
obligations are no longer secured by a Lien or (ii) any Lien of any kind
securing any First Priority Lien Obligation of Parent, the Issuer or any
Subsidiary Guarantor without effectively providing that the Notes or the
applicable Note Guarantee, as the case may be, shall be granted a second
priority security interest (subject to Permitted Liens) upon the assets or
property constituting the collateral for such First Priority Lien Obligations,
except as set forth under the Security Documents; provided, however, that, with
respect to this clause (ii), if granting such second priority security interest
requires the consent of a third party, the Issuer will use commercially
reasonable efforts to obtain such consent with respect to the second priority
interest for the benefit of the Trustee on behalf of the Holders; provided
further, however, that, with respect to this clause (ii), if such third party
does not consent to the granting of such second priority security interest after
the use of such commercially reasonable efforts, Parent, the Issuer or such
Subsidiary Guarantor, as the case may be, will not be required to provide such
security interest.

      SECTION 4.13 Business Activities.

            (1) Prior to the Merger Date, Parent and Merger Dub will not engage
      in any activity other than as necessary to perform its obligations under
      this Indenture or the Merger Agreement.

            (2) From and after the Merger Date, Parent and the Issuer will not,
      and will not permit any of Parent's Restricted Subsidiaries to, engage in
      any business other than

                                       70


      Permitted Businesses, except to such extent as would not be material to
      Parent, the Issuer and Parent's Restricted Subsidiaries taken as a whole.

      SECTION 4.14 Corporate Existence. Subject to Article 5 hereof, Parent and
the Issuer shall do or cause to be done all things necessary to preserve and
keep in full force and effect:

            (1) its corporate existence, and the corporate, partnership or other
      existence of each of its Subsidiaries, in accordance with the respective
      organizational documents (as the same may be amended from time to time) of
      Parent, the Issuer or any such Subsidiary; and

            (2) the rights (charter and statutory), licenses and franchises of
      Parent, the Issuer and its Subsidiaries; provided, however, that the
      Issuer shall not be required to preserve any such right, license or
      franchise, or the corporate, partnership or other existence of any of its
      Subsidiaries, if at least two Officers of the Issuer, one of which is the
      Chief Executive Officer or the Chief Financial Officer of the Issuer,
      shall determine that the preservation thereof is no longer desirable in
      the conduct of the business of Parent, the Issuer and their respective
      Subsidiaries, taken as a whole, and that the loss thereof is not adverse
      in any material respect to the Holders.

      SECTION 4.15 Offer to Repurchase Upon Change of Control.

      (a) If a Change of Control occurs, the Issuer will make an offer (a
"Change of Control Offer") to each Holder to repurchase all or any part (equal
to $1,000 or an integral multiple of $1,000 in excess thereof) of each Holder's
Notes at a purchase price equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest on the Notes repurchased, if any, to,
but not including, the date of purchase, subject to the rights of the Holders on
the relevant record date to receive interest due on the relevant interest
payment date (the "Change of Control Payment"). Within 30 days following any
Change of Control, the Issuer will or will cause the Trustee to mail a notice to
each Holder describing the transaction or transactions that constitute the
Change of Control and stating:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.15 and that all Notes tendered and not withdrawn
      will be accepted for payment;

            (2) the purchase price and the purchase date, which shall be no
      earlier than 30 days and no later than 60 days from the date such notice
      is mailed (the "Change of Control Payment Date");

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

            (4) that, unless the Issuer defaults in the payment of the Change of
      Control Payment, all Notes accepted for payment pursuant to the Change of
      Control Offer will cease to accrue interest after the Change of Control
      Payment Date;

            (5) that Holders electing to have any Notes purchased pursuant to a
      Change of Control Offer will be required to surrender the Notes, with the
      form entitled "Option of Holder to Elect Purchase" attached to the Notes
      completed, or transfer by book-entry

                                       71


      transfer, to the Paying Agent at the address specified in the notice prior
      to the close of business on the third Business Day preceding the Change of
      Control Payment Date;

            (6) that Holders will be entitled to withdraw their election if the
      Paying Agent receives, not later than the close of business on the second
      Business Day preceding the Change of Control Payment Date, a telegram,
      telex, facsimile transmission, email or letter setting forth the name of
      the Holder, the principal amount of Notes the Holder delivered for
      purchase, and a statement that such Holder is withdrawing his election to
      have such Notes purchased; and

            (7) that Holders whose Notes are being purchased only in part will
      be issued new Notes equal in principal amount to the unpurchased portion
      of the Notes surrendered, which unpurchased portion must be equal to
      $1,000 in principal amount or an integral multiple of $1,000 in excess
      thereof.

      The Issuer will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change in Control. To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.15, the Issuer will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations under this Section 4.15 by virtue of such compliance.

            (b) On the Change of Control Payment Date, the Issuer will, to the
      extent lawful:

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

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

                  (3) 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 Issuer.

            Upon receipt of the Change of Control Payment and Officers'
      Certificate described above, the Paying Agent will promptly mail or wire
      transfer to each Holder of Notes properly tendered and so accepted 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 $2,000 or an integral multiple of $1,000 in excess
      thereof. Any Note so accepted for payment will cease to accrue interest on
      and after the Change of Control Payment Date. The Issuer will publicly
      announce the results of the Change of Control Offer on or as soon as
      reasonably practicable after the Change of Control Payment Date.

                                       72


            (c) Notwithstanding anything to the contrary in this Section 4.15,
      the Issuer will not be required to make a Change of Control Offer upon a
      Change of Control if (1) a third party makes the Change of Control Offer
      in the manner, at the times and otherwise in compliance with the
      requirements set forth in this Section 4.15 and purchases all Notes
      properly tendered and not withdrawn under the Change of Control Offer, or
      (2) notice of redemption has been given pursuant to Section 3.07, unless
      and until there is a default in payment of the applicable redemption
      price. Notwithstanding anything to the contrary in this Section 4.15, a
      Change of Control Offer may be made in advance of a Change of Control,
      conditional upon such Change of Control, if a definitive agreement is in
      place for the Change of Control at the time of making of the Change of
      Control Offer.

      SECTION 4.16 No Layering of Debt. Parent and the Issuer will not incur,
and will not permit any Subsidiary Guarantor to incur, any Indebtedness
(including Permitted Debt) that is contractually subordinated in right of
payment to any other Indebtedness of Parent, the Issuer or such Subsidiary
Guarantor unless such Indebtedness is also contractually subordinated in right
of payment to the Notes and the applicable Note Guarantee on substantially
identical terms; provided, however, that no Indebtedness will be deemed to be
contractually subordinated in right of payment to any other Indebtedness of
Parent, the Issuer or any Subsidiary Guarantor solely by virtue of being
unsecured or by virtue of being secured on a first or junior Lien basis.

      SECTION 4.17 Limitation on Sale and Leaseback Transactions. Parent and the
Issuer will not, and will not permit any of Parent's Restricted Subsidiaries to,
enter into any sale and leaseback transaction; provided that Parent, the Issuer
or any Restricted Subsidiary of Parent may enter into a sale and leaseback
transaction if:

            (1) Parent, the Issuer or that Restricted Subsidiary, as applicable,
      could have (a) incurred Indebtedness in an amount equal to the
      Attributable Debt relating to such sale and leaseback transaction under
      the Fixed Charge Coverage Ratio test in Section 4.09(a) and (b) incurred a
      Lien to secure such Indebtedness pursuant to the provisions of Section
      4.12 hereof;

            (2) the gross cash proceeds of that sale and leaseback transaction
      are at least equal to the Fair Market Value, as determined in good faith
      by the Board of Directors of the Issuer 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

            (3) the transfer of assets in that sale and leaseback transaction is
      permitted by, and Parent, the Issuer or the applicable Restricted
      Subsidiary applies the proceeds of such transaction in compliance with,
      Section 4.10.

      SECTION 4.18 Payments for Consent. Parent and the Issuer will not, and
will not permit any of Parent's Restricted Subsidiaries to, directly or
indirectly, pay or cause to be paid any consideration to or for the benefit of
any Holder for or as an inducement to any consent, waiver or amendment of any of
the terms or provisions of this Indenture or the Notes unless such consideration
is offered to be paid and is paid to all Holders that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

                                       73


      SECTION 4.19 Additional Note Guarantees. Parent and the Issuer will not
permit any of Parent's Restricted Subsidiaries, directly or indirectly, to
guarantee the payment of any other Indebtedness of Parent, the Issuer or any of
Parent's Restricted Subsidiaries unless such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture in the form of
Exhibit F hereto and Note Guarantee providing for the guarantee of the payment
of the Notes by such Restricted Subsidiary, which guarantee will be senior to or
pari passu with such Restricted Subsidiary's guarantee of such other
Indebtedness, and simultaneously executes and delivers the applicable Security
Documents pursuant to which its assets (of the same type as the assets of
Parent, the Issuer and the other Subsidiary Guarantors constituting Collateral)
will become part of the Collateral and will secure the Notes and Note Guarantees
in the manner specified in this Indenture and the Security Documents.

      SECTION 4.20 Designation of Restricted and Unrestricted Subsidiaries. The
Board of Directors of the Issuer may designate any Subsidiary (including any
newly acquired or newly formed Subsidiary or Person becoming a Subsidiary
through merger or consolidation or Investment therein) 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 Parent, the Issuer and
Parent's Restricted Subsidiaries in the Subsidiary designated as an Unrestricted
Subsidiary shall be deemed to be an Investment made as of the time of the
designation and will reduce the amount available for Restricted Payments under
Section 4.07 or under one or more clauses of the definition of "Permitted
Investments", as determined by the Issuer. That designation will only be
permitted if such Investment would be permitted at that time and if the
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary.

      Any designation of a Subsidiary of Parent as an Unrestricted Subsidiary
will be evidenced to the Trustee by filing with the Trustee a certified copy of
a resolution of the Board of Directors of the Issuer giving effect to such
designation and an Officers' Certificate certifying that such designation
complied with the conditions specified in clauses (1) to (4) of the definition
of "Unrestricted Subsidiary" and was permitted under Section 4.07. If, at any
time, any Unrestricted Subsidiary would fail to meet the preceding requirements
specified in clauses (1) to (4) of the definition of "Unrestricted Subsidiary",
it will thereafter cease to be an Unrestricted Subsidiary for purposes of this
Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred
by a Restricted Subsidiary of Parent as of such date and, if such Indebtedness
is not permitted to be incurred as of such date under Section 4.09, the Issuer
will be in default of such covenant. The Board of Directors of the Issuer may at
any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of
Parent; provided that such designation will be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of Parent of any outstanding
Indebtedness of such Unrestricted Subsidiary, and such designation will only be
permitted if (1) such Indebtedness is permitted under Section 4.09, calculated
on a pro forma basis as if such designation had occurred at the beginning of the
four-quarter reference period; and (2) no Event of Default would be in existence
following such designation.

      SECTION 4.21 Amendment of Security Documents. The Issuer shall not amend,
modify or supplement, or permit or consent to any amendment, modification or
supplement of, the Security Documents in any way that would be adverse to the
Holders in any material respect, except as described in the Security Documents
or as permitted under Article 9.

                                       74


      SECTION 4.22 After-Acquired Property. If Parent, the Issuer or any
Subsidiary Guarantor shall acquire any First Priority After-Acquired Property,
Parent, the Issuer or such Subsidiary Guarantor shall execute and deliver such
mortgages, deeds of trust, security instruments, financing statements and
certificates and opinions of counsel as shall be reasonably necessary to vest in
the Trustee on behalf of the Holders a perfected security interest, subject only
to Permitted Liens, in such First Priority After-Acquired Property and to have
such First Priority After-Acquired Property (but subject to certain limitations,
if applicable, including as described in the Security Documents) added to the
Collateral, and thereupon all provisions of this Indenture relating to the
Collateral shall be deemed to relate to such First Priority After-Acquired
Property to the same extent and with the same force and effect; provided,
however, that if granting such second priority security interest in such First
Priority After-Acquired Property requires the consent of a third party, the
Issuer will use commercially reasonable efforts to obtain such consent with
respect to the second priority interest for the benefit of the Trustee on behalf
of the Holders; provided further, however, that if such third party does not
consent to the granting of such second priority security interest after the use
of such commercially reasonable efforts, Parent, the Issuer or such Subsidiary
Guarantor, as the case may be, will not be required to provide such security
interest.

                                    ARTICLE 5

basis for Issuer and its Subsidiaries), in one or more related transactions to
another Person, unless:

            (1) either (a) the Issuer is the surviving entity; or (b) the Person

      would, on the date of such transaction

                                       75

      Charge Coverage Ratio that is at least equal to the actual Fixed Charge
      Coverage Ratio for Parent as of such date; and

            (5) the Issuer delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that such consolidation, merger or
      transfer and such supplemental indenture (if any) complies with this
      Indenture, that all conditions precedent in this Indenture relating to
      such transaction have been satisfied and that the supplemental indenture
      is enforceable;

      provided, that, clause (4) of this Section 5.01(a) will not apply to:

            (i) a merger of the Issuer with an Affiliate solely for the purpose
      of reincorporating the Issuer in another jurisdiction; or

            (ii) any consolidation or merger, or any sale, assignment, transfer,
      conveyance, lease or other disposition of assets between or among the
      Issuer and any of the Restricted Subsidiaries.

      (b) Parent will not, directly or indirectly, consolidate or merge with or
into another Person (whether or not Parent is the surviving corporation) or
sell, assign, transfer, lease, convey or otherwise dispose of all or

basis for Parent and its Subsidiaries), in one or more related transactions to
another Person, unless:

            (1) either (a) Parent is the surviving entity; or (b) the Person

      merger (if other than Parent) or the Person to which such sale,
      assignment, transfer, lease, conveyance or other disposition has been made

      Trustee;

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

      thereto and to any related financing transactions as if the

                                       76


      same had occurred at the beginning of the applicable four-quarter period,

      transfer and such supplemental indenture (if any) complies with this
      Indenture, that all conditions precedent in this Indenture relating to

            (i) a merger of Parent with an Affiliate solely for the purpose of
      reincorporating Parent in another jurisdiction; or

            (ii) any consolidation or merger, or any sale, assignment, transfer,

to the Trustee supplemental indentures of the type referred to in the clause (2)
of Section 5.01(a) pursuant to which the Company, as the surviving entity of the
Merger, will assume all the obligations of Merger Sub under this Indenture and

of, Merger Sub under this Indenture. Notwithstanding anything in this Article 5
to the contrary, the merger of Merger Sub with and into the Company on the
Merger Date as described in the Merger Agreement shall be permitted under this
Indenture.

      SECTION 5.02 Successor Corporation Substituted. Upon any consolidation or
merger, or any sale, assignment, transfer, lease, conveyance or other
disposition of all or substantially all of the assets of the Issuer or Parent in
a transaction that is subject to, and that complies with the provisions of,
Section 5.01 hereof, the successor corporation formed by such consolidation or
into or with which the Issuer or Parent, as applicable, is merged or to which
such sale, assignment, transfer, lease, conveyance or other disposition is made
shall succeed to, and be substituted for (so that from and after the date of
such consolidation, merger, sale, lease, conveyance or other disposition, the
provisions of this Indenture referring to the "Issuer" or "Parent", as
applicable, shall refer instead to the successor corporation and not to the
Issuer or Parent, as applicable), and may exercise every right and power of the
Issuer or Parent, as applicable, under this Indenture with the same effect as if
such successor Person had been named as the Issuer or Parent, as applicable,
herein; provided, however, that, in the case of the Issuer, the predecessor
Issuer shall not be relieved from the obligation to pay the principal of and
interest on the Notes except in the case of a sale or other disposition of all
or substantially all of the properties or assets of the Issuer (determined on a
consolidated basis for the Issuer and its Subsidiaries), in one or more related
transactions subject to, and in compliance with the provisions of, Section

                              DEFAULTS AND REMEDIES

      SECTION 6.01 Events of Default. Each of the following is an "Event of
Default:"

            (1) default for 30 days in the payment when due of interest on the
      Notes;

            (2) default in the payment when due (at maturity, upon redemption or
      otherwise) of the principal of, or premium, if any, on the Notes;

            (3) failure by Parent, the Issuer or any of Parent's Restricted
      Subsidiaries for five Business Days to comply with the provisions of
      Section 4.15 or Section 5.01 hereof;

            (4) failure by Parent, the Issuer or any of Parent's Restricted
      Subsidiaries for 60 days after notice to the Issuer by the Trustee or the
      Holders of at least 25% in aggregate principal amount of the Notes then
      outstanding voting as a single class to comply with any of the other
      agreements in this Indenture;

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

                  (A) is caused by a failure to pay any portion of the principal
            of such Indebtedness when due and payable after the expiration of
            the grace period provided in such Indebtedness (a "Payment
            Default"); or

                  (B) results in the acceleration of such Indebtedness prior to
            its Stated Maturity,

      and, in each case, the principal amount of any such Indebtedness, together
      with the principal amount of any other such Indebtedness under which there
      has been a Payment Default or the maturity of which has been so
      accelerated, aggregates $30.0 million or more;

            (6) failure by Parent, the Issuer or any of Parent's Restricted
      Subsidiaries to pay final and nonappealable judgments entered by a court
      or courts of competent jurisdiction aggregating in excess of $30.0 million
      (net of any amounts which are covered by insurance or bonded), which
      judgments are not paid, waived, satisfied, discharged or stayed for a
      period of 60 days;

            (7) except as permitted by this Indenture, any Note Guarantee is
      held in any judicial proceeding to be unenforceable or invalid or ceases
      for any reason to be in full force and effect (other than in accordance
      with the terms of such Note Guarantee and this Indenture) or Parent or any
      Subsidiary Guarantor, or any Person acting on behalf of

                                       78


      Parent or any Subsidiary Guarantor denies or disaffirms its obligations
      under its Note Guarantee;

            (8) Parent, the Issuer or any of Parent's Restricted Subsidiaries

      that, taken together, would constitute a Significant Subsidiary 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, or

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

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

                  (A) is for relief against Parent, the Issuer or any of
            Parent's Restricted Subsidiaries that is a Significant Subsidiary or
            any group of Restricted Subsidiaries of Parent that, taken together,
            would constitute a Significant Subsidiary in an involuntary case;

                  (B) appoints a custodian of Parent, the Issuer or any of
            Parent's Restricted Subsidiaries that is a Significant Subsidiary or
            any group of Restricted Subsidiaries of Parent that, taken together,
            would constitute a Significant Subsidiary or for all or
            substantially all of the property of Parent, the Issuer or any of
            Parent's Restricted Subsidiaries that is a Significant Subsidiary or
            any group of Restricted Subsidiaries of Parent that, taken together,
            would constitute a Significant Subsidiary; or

                  (C) orders the liquidation of Parent, the Issuer or any of
            Parent's Restricted Subsidiaries that is a Significant Subsidiary or
            any group of Restricted Subsidiaries of Parent that, taken together,
            would constitute a Significant Subsidiary;

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

            (10) unless all the Collateral has been released from the applicable
      Liens in accordance with the provisions of the Security Documents, default
      by Parent, the Issuer or any Restricted Subsidiary of Parent in the
      performance of the Security Documents, or the occurrence of any other
      event, in each case that adversely affects the enforceability, validity,
      perfection or priority of such Liens on a material portion of the
      Collateral granted to the Second Lien Agent for the benefit of the Trustee
      and the Holders, the repudiation or disaffirmation by Parent, the Issuer
      or any Restricted Subsidiary of Parent of its material obligations under
      the Security Documents or the determination in a judicial

                                       79


      proceeding that the Security Documents are unenforceable or invalid
      against Parent, the Issuer or any Restricted Subsidiary of Parent party
      thereto for any reason with respect to a material portion of the
      Collateral (which default, occurrence, repudiation, disaffirmation or
      determination is not rescinded, stayed or waived by the Persons having
      such authority pursuant to the Security Documents or otherwise cured
      within 60 days after the Issuer receives notice thereof specifying such
      occurrence from the Trustee or the Holders of at least 25% of the
      outstanding principal amount of the Notes and demanding that such default,
      occurrence, repudiation, disaffirmation or determination be remedied).

      SECTION 6.02 Acceleration. In the case of an Event of Default specified in
clause (8) or (9) of Section 6.01, the principal or, premium, if any, and
accrued interest on all of the Notes then outstanding shall automatically become
due and payable immediately without any further declaration or other act on the
part of the Trustee or any Holder. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then outstanding, by written notice to the Issuer (and the
Trustee if such notice is given by the Holders), may, and the Trustee at the
request of such Holders shall, declare the principal of, premium, if any, and
accrued interest on the Notes to be immediately due and payable immediately.

      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 and interest on the Notes or to enforce the performance of
any provision of the Notes or this Indenture.

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

      SECTION 6.04 Waiver of Past Defaults. The Holders of at least a majority
in principal amount of the outstanding Notes by written notice to the Issuer and
to the Trustee, may waive all past defaults and rescind and annul a declaration
of acceleration and its consequences if (x) all existing Events of Default,
other than the nonpayment of the principal of, premium, if any, and accrued
interest on the Notes that have become due solely by such declaration of
acceleration, have been cured or waived and (y) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction. 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. The Holders of at least a majority in
aggregate principal amount of the outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability or expense that is not
adequately indemnified in the judgment of the Trustee, or that the Trustee
determines in good

                                       80


faith may be unduly prejudicial to the rights of Holders of Notes not joining in
the giving of such direction and may take any other action it deems proper that
is not inconsistent with any such direction received from Holders of Notes.

      SECTION 6.06 Limitation on Suits. Except to enforce the right to receive
payment of principal, premium, if any, or interest when due, no Holder may
pursue any remedy with respect to this Indenture or the Notes unless:

            (1) such Holder has previously given the Trustee notice that an
      Event of Default is continuing;

            (2) Holders of at least 25% in aggregate principal amount of the
      then outstanding Notes have requested the Trustee to pursue the remedy;

            (3) such Holders have offered the Trustee security or indemnity
      satisfactory to it against any loss, liability or expense;

            (4) the Trustee has not complied with such request within 60 days
      after the receipt thereof and the offer of security or indemnity; and

            (5) Holders of a majority in aggregate principal amount of the then
      outstanding Notes have not given the Trustee a direction inconsistent with
      such request within such 60-day period.

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

      SECTION 6.07 Rights of Holders of Notes to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
of a Note to receive payment of principal, premium, if any, and interest on the
Note, on or after the respective due dates expressed in the Note (including in
connection with an offer to purchase), or to bring suit for the enforcement of
any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder.

      SECTION 6.08 Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to
recover judgment in its own name and as Trustee of an express trust against the
Issuer for the whole amount of principal of, premium and interest remaining
unpaid on the Notes and interest on overdue principal and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

      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 Issuer (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money

                                       81


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,
reasonable 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 and interest, ratably, without preference or priority of any
kind, according to the amounts due and payable on the Notes for principal,
premium and interest, respectively; and

      Third: to the Issuer 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 and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section 6.11 does not apply
to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07
hereof, or a suit by Holders of more than 10% in principal amount of the then
outstanding Notes.

                                   ARTICLE 7
                                    TRUSTEE

      SECTION 7.01 Duties of Trustee.

                                       82


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

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

                  (1) the duties of the Trustee will 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, in the case of certificates specifically
            required by any provision herein to be furnished to it, the Trustee
            will examine the certificates and opinions to determine whether or
            not they conform to the requirements of this Indenture.

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

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

                  (2) the Trustee will 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 will 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 7.01.

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

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

                                       83


      SECTION 7.02 Rights of Trustee.

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

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

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

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

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

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

            (g) In no event shall the Trustee be responsible or liable for
      special, indirect, or consequential loss or damage of any kind whatsoever
      (including, but not limited to, loss of profit) irrespective of whether
      the Trustee has been advised of the likelihood of such loss or damage and
      regardless of the form of action.

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

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

                                       84


            (j) The Trustee may request that the Issuer deliver an Officers'
      Certificate setting forth the names of individuals and/or titles of
      officers authorized at such time to take specified actions pursuant to
      this Indenture, which Officers' Certificate may be signed by any person
      authorized to sign an Officers' Certificate, including any person
      specified as so authorized in any such certificate previously delivered
      and not superseded.

            (k) The permissive rights of the Trustee to do certain things
      enumerated in this Indenture shall not be construed as a duty and the
      Trustee shall not be answerable for other than its negligence or willful
      default with respect to such permissive rights.

            (l) The Trustee shall not be bound to make any inquiry or
      investigation into the facts or matters stated in any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      direction, consent, order, bond, note or other paper or document unless
      requested in writing so to do by the holders of a majority in aggregate
      principal amount of the Notes or any series affected then outstanding;
      provided, however, that if the payment within a reasonable time to the
      Trustee of the costs and expenses or liabilities likely
      to be incurred by it in the making of such investigation is, in the
      opinion of the Trustee, not reasonably assured to the Trustee by the
      security conferred upon it by the terms of this Indenture, the Trustee may
      require reasonable indemnity against such costs, expenses or liabilities
      as a condition to so proceeding; and the reasonable expense of such
      investigation shall be paid by the Issuer, or, if paid by the Trustee
      shall be repaid by the Issuer upon demand.

            (m) The Trustee shall not be responsible or liable for special,
      indirect or consequential loss or damage of any kind whatsoever
      (including, but not limited to, loss or profit) irrespective of whether
      the Trustee has been advised of the likelihood of such loss or damage and
      regardless of the form of the action.

            (n) The Trustee shall not be required to give any note, bond, or
      surety in respect of the execution of the trusts and powers under this
      Indenture.

            (o) The Trustee shall not be responsible or liable for any failure
      or delay in the performance of its obligations under this Indenture
      arising out of or caused, directly or indirectly, by circumstances beyond
      its reasonable control, including without limitation, acts of God;
      earthquakes; fire; flood; terrorism; wars and other military disturbances;
      sabotage; epidemics; riots; interruptions; loss or malfunction of
      utilities, computer (hardware or software) or communication services;
      accidents; labor disputes; acts of civil or military authorities and
      governmental action.

      SECTION 7.03 Individual Rights of Trustee. The Trustee in its individual
or any other capacity may become the owner or pledgee of Notes and may otherwise
deal with the Issuer or any Affiliate of the Issuer 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 (if this Indenture
has been qualified under the TIA) or resign. Any Agent may do the same with like
rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

                                       85


      SECTION 7.04 Trustee's Disclaimer. The Trustee will not be responsible for
and makes no representation as to the validity or adequacy of this Indenture or
the Notes, it shall not be accountable for the Issuer's use of the proceeds from
the Notes or any money paid to the Issuer or upon the Issuer's direction under
any provision of this Indenture, it will not be responsible for the use or
application of any money received by any Paying Agent other than the Trustee,
and it will 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 will mail to
Holders a notice of the Default or Event of Default within 90 days after it
occurs. Except in the case of a Default or Event of Default in payment of
principal of, premium, or interest on, any Note, the Trustee may withhold the
notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders.

      SECTION 7.06 Reports by Trustee to Holders of the Notes.

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

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

      SECTION 7.07 Compensation and Indemnity.

            (a) The Issuer will pay to the Trustee from time to time
      compensation for its acceptance of this Indenture and services hereunder.
      The Trustee's compensation will not be limited by any law on compensation
      of a trustee of an express trust. The Issuer will 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 will include the reasonable compensation,
      disbursements and expenses of the Trustee's agents and counsel.

            (b) Parent, the Issuer and the Subsidiary Guarantors, jointly and
      severally, will indemnify the Trustee against any and all losses,
      liabilities or expenses incurred by it arising out of or in connection
      with the acceptance or administration of its duties under this Indenture,
      including the costs and expenses of enforcing this Indenture against
      Parent, Issuer and the Subsidiary Guarantors (including this Section 7.07)
      and defending itself against any claim (whether asserted by Parent,
      Issuer, the Subsidiary Guarantors,

                                       86


      any Holder or any other Person) or liability in connection with the
      exercise or performance of any of its powers or duties hereunder, except
      to the extent any such loss, liability, claim, damage or expense as shall
      be determined to have been caused by its negligence or bad faith. The
      Trustee will notify the Issuer promptly of any claim for which it may seek
      indemnity. Failure by the Trustee to so notify the Issuer will not relieve
      Parent, the Issuer or any of the Subsidiary Guarantors of their
      obligations hereunder. Parent, Issuer or such Subsidiary Guarantor will
      defend the claim and the Trustee will cooperate in the defense. The
      Trustee may have separate counsel and the Issuer will pay the reasonable
      fees and expenses of such counsel. None of Parent, the Issuer or any
      Subsidiary Guarantor need pay for any settlement made without its consent,
      which consent will not be unreasonably withheld.

            (c) The obligations of Parent, Issuer and the Subsidiary Guarantors
      under this Section 7.07 will survive the satisfaction and discharge of
      this Indenture.

            (d) To secure Parent's, the Issuer's and the Subsidiary Guarantors'
      payment obligations in this Section 7.07, the Trustee will have a Lien
      prior to the Notes on all money or property held or collected by the
      Trustee, except that held in trust to pay principal and interest on
      particular Notes. Such Lien will survive the satisfaction and discharge of
      this Indenture.

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

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

      SECTION 7.08 Replacement of Trustee.

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

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

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

                  (2) 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,

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

                                       87


                  (4) the Trustee becomes incapable of acting.

            (c) If the Trustee resigns or is removed or if a vacancy exists in
      the office of Trustee for any reason, the Issuer will 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 Issuer.

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

            (e) 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
      hereof, such Holder may petition any court of competent jurisdiction for
      the removal of the Trustee and the appointment of a successor Trustee.

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

      SECTION 7.10 Eligibility; Disqualification. There will at all times be a
Trustee hereunder that is a corporation organized and doing business under the
laws of the United States of America or of any state thereof that is authorized
under such laws to exercise corporate trustee power, that is subject to
supervision or examination by federal or state authorities and that has a
combined capital and surplus of at least $100.0 million as set forth in its most
recent published annual report of condition.

      This Indenture will 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 Issuer. 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
Issuer may, any time, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, elect to have either Section
8.02 or 8.03 hereof be applied to all outstanding Notes and the Note Guarantees
upon compliance with the conditions set forth below in this Article 8.

      SECTION 8.02 Legal Defeasance and Discharge. Upon the Issuer's exercise
under Section 8.01 hereof of the option applicable to this Section 8.02, Parent,
the Issuer and each of the Subsidiary Guarantors will, subject to the
satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to
have been discharged from their obligations with respect to all outstanding
Notes (including the Note Guarantees) on the date the conditions set forth below
are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal
Defeasance means that Parent, the Issuer and the Subsidiary Guarantors will be
deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Notes (including the Note Guarantees), which will 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 clauses (1) and (2) below, and
to have satisfied all their other obligations under such Notes, the Note
Guarantees and this Indenture (and the Trustee, on demand of and at the expense
of the Issuer, shall execute proper instruments acknowledging the same), except
for the following provisions which will survive until otherwise terminated or
discharged hereunder:

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

            (2) the Issuer's obligations with respect to such Notes under
      Article 2 and Section 4.02 hereof;

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

            (4) this Article 8.

      Subject to compliance with this Article 8, the Issuer 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 Issuer's exercise under Section
8.01 hereof of the option applicable to this Section 8.03, Parent, the Issuer
and each of the Subsidiary Guarantors will, subject to the satisfaction of the
conditions set forth in Section 8.04 hereof, be released from each of their
obligations under the covenants contained in Sections 3.09, 4.07, 4.08, 4.09,
4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 hereof with
respect to the outstanding Notes on and after the date the conditions set forth
in Section 8.04 hereof are satisfied (hereinafter, "Covenant Defeasance"), and
the Notes will thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders

                                       89


(and the consequences of any thereof) in connection with such covenants, but
will continue to be deemed "outstanding" for all other purposes hereunder (it
being understood that such Notes will not be deemed outstanding for accounting
purposes). For this purpose, Covenant Defeasance means that, with respect to the
outstanding Notes and Note Guarantees, Parent, the Issuer and the Subsidiary
Guarantors may omit to comply with and will 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 will 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 and Note
Guarantees will be unaffected thereby. In addition, upon the Issuer's exercise
under Section 8.01 hereof of the option applicable to this Section 8.03 hereof,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
Sections 6.01(5) and 6.01(6) hereof will not constitute Events of Default.

      SECTION 8.04 Conditions to Legal or Covenant Defeasance. In order to
exercise either Legal Defeasance or Covenant Defeasance under either Section
8.02 or 8.03 hereof:

            (1) the Issuer must irrevocably deposit with the Trustee, in trust,
      for the benefit of the Holders, 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 investment bank, appraisal firm or
      firm of independent public accountants, to pay the principal of, or
      interest and premium, if any, on, the outstanding Notes on the stated date
      for payment thereof or on the applicable redemption date, as the case may
      be, and the Issuer must specify whether the Notes are being defeased to
      such stated date for payment or to a particular redemption date;

            (2) in the case of an election under Section 8.02 hereof, the Issuer
      has delivered to the Trustee an Opinion of Counsel reasonably acceptable
      to the Trustee (subject to customary exceptions and exclusions) confirming
      that:

                  (A) Parent and the Issuer has received from, or there has been
            published by, the Internal Revenue Service a ruling; or

                  (B) since the date of this Indenture, there has been a change
            in the applicable federal income tax law,

      in either case to the effect that, and based thereon such Opinion of
      Counsel shall confirm that, the Holders of the outstanding Notes will not
      recognize income, gain or loss for federal income tax purposes as a result
      of such Legal Defeasance and will be subject to federal income tax on the
      same amounts, in the same manner and at the same times as would have been
      the case if such Legal Defeasance had not occurred,

            (3) in the case of an election under Section 8.03 hereof, the Issuer
      has delivered to the Trustee an Opinion of Counsel reasonably acceptable
      to the Trustee (subject to customary exceptions and exclusions) confirming
      that the Holders of the outstanding Notes will not recognize income, gain

                                       90


      or loss for federal income tax purposes as a result of such Covenant
      Defeasance and will be subject to federal income tax on the same amounts,
      in the same manner and at the same times as would have been the case if
      such Covenant Defeasance had not occurred;

            (4) no Default or Event of Default 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 and
      the grant of any Lien securing such borrowing);

            (5) such Legal Defeasance or Covenant Defeasance will not result in
      a breach or violation of, or constitute a default under, any material
      agreement or instrument (other than this Indenture) to which Parent, the
      Issuer or any of their respective Subsidiaries is a party or by which
      Parent, the Issuer or any of their respective Subsidiaries is bound,
      including the Credit Agreement;

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

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

      SECTION 8.05 Deposited Money and Government Securities to be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money
and non-callable Government Securities (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in
respect of the outstanding Notes will 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 Issuer
acting as Paying Agent) as the Trustee may determine, to the Holders of such
Notes of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be segregated from other
funds except to the extent required by law.

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

      Notwithstanding anything in this Article 8 to the contrary, the Trustee
will deliver or pay to the Issuer from time to time upon the request of the
Issuer any money or non-callable Government Securities held by it as provided in
Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section

                                       91


8.04(1) hereof), are in excess of the amount thereof that would then be required
to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

      SECTION 8.06 Repayment to the Issuer. Any money deposited with the Trustee
or any Paying Agent, or then held by the Issuer, in trust pursuant to Section
8.04 or Section 12.01 for the payment of the principal of, premium, if any, or
interest on any Note and remaining unclaimed for two years after such principal,
premium, if any, or interest has become due and payable shall be paid to the
Issuer on its request or (if then held by the Issuer) will be discharged from
such trust; and the Holder of such Note will thereafter be permitted to look
only to the Issuer for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Issuer
as trustee thereof, will 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 Issuer 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 will not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining will be repaid to the Issuer.

      SECTION 8.07 Reinstatement. If the Trustee or Paying Agent is unable to
apply any United States dollars or non-callable Government Securities in
accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of
any order or judgment of any court or governmental authority enjoining,
restraining or otherwise prohibiting such application, then Parent's, the
Issuer's and the Subsidiary Guarantors' obligations under this Indenture and the
Notes and the Note Guarantees will 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 Issuer makes any payment of principal of, premium, if any, or interest on
any Note following the reinstatement of its obligations, the Issuer will be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

                                   ARTICLE 9
                        AMENDMENT, SUPPLEMENT AND WAIVER

      SECTION 9.01 Without Consent of Holders of Notes. Notwithstanding Section
9.02 of this Indenture, without the consent of any Holder of Notes, Parent, the
Issuer, the Subsidiary Guarantors and the Trustee may amend or supplement this
Indenture, the Notes, the Note Guarantees or the Security Documents:

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

            (2) to provide for uncertificated Notes in addition to or in place
      of certificated Notes;

            (3) to provide for the assumption of Parent's, the Issuer's or a
      Subsidiary Guarantor's obligations to the Holders of Notes and Note

                                       92


      Guarantees in the case of a merger or consolidation or sale of all or
      substantially all of Parent's, the Issuer's or such Subsidiary Guarantor's
      assets, as applicable;

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

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

            (6) to conform the text of this Indenture, the Note Guarantees or
      the Notes to any provision of the "Description of the Notes" section of
      the Offering Memorandum to the extent that such provision in that
      "Description of the Notes" was intended to be a verbatim recitation of a
      provision of this Indenture, the Note Guarantees or the Notes;

            (7) to provide for the issuance of Additional Notes in accordance
      with the limitations set forth in this Indenture;

            (8) to allow any Subsidiary Guarantor to execute a supplemental
      indenture and/or a Note Guarantee with respect to the Notes and to release
      Subsidiary Guarantors from the Note Guarantee in accordance with the terms
      of this Indenture as of the date of this Indenture; or

            (9) to make, complete or confirm any grant of Collateral permitted
      or required by this Indenture, the Intercreditor Agreement or any of the
      Security Documents or any release of Collateral that becomes effective as
      set forth in this Indenture, the Intercreditor Agreement or any of the
      Security Documents.

      After an amendment becomes effective, the Issuer is required to mail to
each registered Holder of the Notes a notice briefly describing such amendment.
However, the failure to give such notice to all Holders of the Notes, or any
defect therein, will not impair or affect the validity of the amendment.

      Upon the request of the Issuer accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
indenture permitted by the terms of this Indenture, and upon receipt by the
Trustee of the documents described in Section 13.04 hereof, the Trustee will
join with Parent, the Issuer and the Subsidiary Guarantors in the execution of
any such amended or supplemental indenture, but the Trustee will 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, Parent, the Issuer, the Subsidiary Guarantors and the Trustee
may amend or supplement this Indenture, the Note Guarantees, the Notes and the
Security Documents with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes (including, without limitation,
Additional Notes, if any) then outstanding voting as a single class (including,
without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04

                                       93


and 6.07 hereof, any existing Default or Event of Default (other than a Default
or Event of Default in the payment of the principal of, premium, if any, or
interest on the Notes, except a payment default resulting from an acceleration
that has been rescinded) or compliance with any provision of this Indenture, the
Note Guarantees, the Notes and the Security Documents may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then
outstanding Notes (including, without limitation, Additional Notes, if any)
voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the
Notes). Section 2.08 hereof shall determine which Notes are considered to be
"outstanding" for purposes of this Section 9.02.

      Upon the request of the Issuer accompanied by a resolution of its Board of
Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 13.04 hereof, the Trustee will
join with Parent, the Issuer and the Subsidiary Guarantors 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 will not be obligated to, enter into such amended or supplemental Indenture.

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

      After an amendment, supplement or waiver under this Section 9.02 becomes
effective, the Issuer will mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuer to mail such notice, or any defect therein, will not, however, in any
way impair or affect the validity of any such amendment, supplement or waiver.
However, without the consent of each Holder affected, an amendment, supplement
or waiver under this Section 9.02 may not (with respect to any Notes held by a
non-consenting Holder):

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

            (2) reduce the principal of or extend the fixed maturity of any Note
      or alter the provisions with respect to the redemption of the Notes (other
      than the provisions of Sections 3.09, 4.10 or 4.15 hereof);

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

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

                                       94


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

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

            (7) waive a redemption payment with respect to any Note (other than
      a payment required by Sections 3.09, 4.10 or 4.15 hereof);

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

            (9) release any Collateral from the Liens created by the Security
      Documents except as specifically provided for in this Indenture or the
      Security Documents;

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

            (11) make any change in the provisions in the Intercreditor
      Agreement or this Indenture dealing with the application of proceeds of
      Collateral that would adversely affect the Holders of the Notes; or

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

      In addition, any amendment to, or waiver of, the provisions of this
Indenture or any Security Document that has the effect of releasing all or
substantially all of the Collateral from the Liens securing the Notes will
require the consent of the Holders of at least 66 2/3% in aggregate principal
amount of the outstanding Notes.

      SECTION 9.03 Compliance. Every amendment or supplement to this Indenture
or the Notes will be set forth in an amended or supplemental indenture that
complies with this Indenture.

      SECTION 9.04 Revocation and Effect of Consents. Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of a Note is
a continuing consent by the Holder of a Note and every subsequent Holder of a
Note or portion of a Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on any Note. However,
any such Holder of a Note or subsequent Holder of a Note may revoke the consent
as to its Note if the Trustee receives written notice of revocation before the
date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

      For purposes of this Indenture, the consent of the Holder of a Global
Security shall be deemed to include any consent delivered by any member of, or
participant in, any Depository or DTC, any nominees thereof and their respective
successors and assigns, or such other depository institution hereinafter
appointed by the Issuer ("Depository Entity") by electronic means in

                                       95


accordance with the Automated Tender Offer Procedures system or other customary
procedures of, and pursuant to authorization by, such Depository Entity.

      The Issuer may, but shall not be obligated to, fix a record date for the
purpose of determining the Holders entitled to give their consent or take any
other action required or permitted to be taken pursuant to this Indenture. If a
record date is fixed, then notwithstanding the first paragraph of this Section
9.04, those Persons who were Holders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to give such
consent or to revoke any consent previously given or to take any such action,
whether or not such Persons continue to be Holders after such record date. No
such consent shall become valid or effective more than 120 days after such
record date.

      Any Holder entitled hereunder to give, make or take any action under this
Indenture with regard to any particular Note may do so, or duly appoint any
Person or Persons as its agent or agents to do so, with regard to all or any
part of the principal amount of such Note.

      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 Issuer 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.

      Any consent of any Holder of Notes may include, without limitation, any
consent obtained in connection with a tender offer or exchange offer for, or
purchase of, Notes.

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

      SECTION 9.06 Trustee to Sign Amendments, etc. The Trustee will 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 Issuer may not sign an amended or
supplemental indenture until its Board of Directors approves it. On the Merger
Date, the Trustee is hereby directed to execute and deliver a supplemental
indenture of the type referred to in the clause (2) of Section 5.01(a) pursuant
to which the Company, as the surviving entity of the Merger, will assume all the
obligations of Merger Sub under this Indenture and will succeed to, and be
substitute for, and may exercise every right and power of, Merger Sub under this
Indenture. Except with respect to the supplemental indenture referred to in the
immediately prior sentence, in executing any amended or supplemental indenture,
the Trustee will be provided with and (subject to Section 7.01 hereof) will be
fully protected in relying upon, in addition to the documents required by
Section 13.04 hereof, an Officers' Certificate and an Opinion of Counsel stating
that the execution of such amended or supplemental indenture is authorized or
permitted by this Indenture.

                                   ARTICLE 10
                                   COLLATERAL

      SECTION 10.01 Security Documents. Subject to the provisions of the
Intercreditor Agreement, the payment of the principal of and interest and

                                       96


premium, if any, on the Notes when due, whether on an interest payment date, at
maturity, by acceleration, repurchase, redemption or otherwise and whether by
the Issuer pursuant to the Notes or by Parent or any Subsidiary Guarantor

      SECTION 10.04 Release of Liens.

            (a) Subject to clauses (b) and (c) of this Section 10.04, Collateral
      may be released from the Lien and security interest created by the
      Security Documents at any time or from time to time in accordance with the
      provisions of the Security Documents, the Intercreditor Agreement or as
      provided hereby. Upon the request of the Issuer pursuant to an Officers'
      Certificate and Opinion of Counsel certifying that all conditions
      precedent hereunder have been met, Parent, the Issuer and the Subsidiary
      Guarantors will be entitled to the release of assets included in the
      Collateral from the Liens securing the Notes, and the Second Lien Agent
      and the Trustee (if the Trustee is not then the Second Lien Agent) shall
      release the same from such Liens at the Issuer's sole cost and expense,
      under any one or more of the following circumstances:

                  (1) subject to the following paragraph, upon the Discharge of
            Senior Lender Claims and concurrent release of all other Liens on
            such property or assets securing First Priority Lien Obligations
            (including all commitments and letters of credit thereunder);

                  (2) to enable Parent, the Issuer or any Subsidiary Guarantor
            to consummate the disposition of such property or assets to the
            extent not prohibited under Section 4.10;

                  (3) in the case of a Subsidiary Guarantor that is released
            from its Note Guarantee with respect to the Notes, the release of
            the property and assets of such Subsidiary Guarantor; or

                  (4) as described under Article 9.

                                       99


            If an Event of Default under the Indenture exists on the date of
      Discharge of Senior Lender Claims, the Second Priority Liens on the
      Collateral securing the Notes will not be released, except to the extent
      the Collateral or any portion thereof was disposed of in order to repay
      the First Priority Lien Obligations secured by the Collateral, and
      thereafter the Trustee (or another designated representative acting at the
      direction of the holders of a majority of outstanding principal amount of
      the Notes and Other Second-Lien Obligations) will have the right to direct
      the First Lien Agent to foreclose upon the Collateral (but in such event,
      the Liens on the Collateral securing the Notes will be released when such
      Event of Default and all other Events of Default under the Indenture cease
      to exist).

            Upon the receipt of an Officers' Certificate from the Issuer, as
      described above, and any necessary or proper instruments of termination,
      satisfaction or release prepared by the Issuer, the Trustee shall instruct
      the Second Lien Agent to execute, deliver or acknowledge such instruments
      or releases to evidence the release of any Collateral permitted to be
      released pursuant to this Indenture or the Security Documents or the
      Intercreditor Agreement.

            (b) Except as otherwise provided in the Intercreditor Agreement, no
      Collateral may be released from the Lien and security interest created by
      the Security Documents unless the Officers' Certificate required by this
      Section 10.04 has been delivered to the Second Lien Agent and the Trustee
      not less than five days prior to the date of such release.

            (c) At any time when a Default or Event of Default has occurred and
      is continuing and the maturity of the Notes has been accelerated (whether
      by declaration or otherwise) and the Trustee has delivered a notice of
      acceleration to the Second Lien Agent, no release of Collateral pursuant
      to the provisions of this Indenture or the Security Documents will be
      effective as against the Holders, except as otherwise provided in the
      Intercreditor Agreement.

      SECTION 10.05 Filing, Recording and Opinions.

            (a) In the event that this Indenture shall be required to be
      qualified, and shall be so qualified, pursuant to the TIA, the Issuer will
      comply with the provisions of TIA ss.314(b) and 314(d), except to the
      extent not required as set forth in any SEC regulation or interpretation
      (including any no-action letter issued by the Staff of the SEC, whether
      issued to the Issuer or any other Person). Following such qualification,
      if any, to the extent the Issuer is required to furnish to the Trustee an
      Opinion of Counsel pursuant to TIA ss.314(b)(2), the Issuer will furnish
      such opinion not more than 60 but not less than 30 days prior to each May
      31.

            Any release of Collateral permitted by Section 10.04 hereof will be
      deemed not to impair the Liens under the Indenture and the Security
      Documents in contravention thereof and, in the event that this Indenture
      shall be required to be qualified, and shall be so qualified, pursuant to
      the TIA, any person that is required to deliver an Officers' Certificate
      or Opinion of Counsel pursuant to Section 314(d) of the TIA, shall be
      entitled

                                      100


      to rely upon the foregoing as a basis for delivery of such certificate or
      opinion. The Trustee may, to the extent permitted by Section 7.01 and 7.02
      hereof, accept as conclusive evidence of compliance with the foregoing
      provisions the appropriate statements contained in such documents and
      Opinion of Counsel.

            (b) If any Collateral is released in accordance with this Indenture
      or any Security Document and if the Issuer has delivered the certificates
      and documents required by the Security Documents and Section 10.04, the
      Trustee will determine whether it has received all documentation required
      by this Indenture in connection with such release and, based on such
      determination and the Opinion of Counsel delivered pursuant to Section
      10.04, will, upon request, deliver a certificate to the Second Lien Agent
      setting forth such determination.

      SECTION 10.06 Powers Exercisable by Receiver or Trustee. In case the
Collateral shall be in the possession of a receiver or trustee, lawfully
appointed, the powers conferred in this Article 10 upon Parent, the Issuer or a
Subsidiary Guarantor with respect to the release, sale or other disposition of
such property may be exercised by such receiver or trustee, and an instrument
signed by such receiver or trustee shall be deemed the equivalent of any similar
instrument of Parent, the Issuer or a Subsidiary Guarantor or of any officer or
officers thereof required by the provisions of this Article 10; and if the
Second Lien Agent or the Trustee shall be in the possession of the Collateral
under any provision of this Indenture, then such powers may be exercised by the
Second Lien Agent or the Trustee.

      SECTION 10.07 Release Upon Termination of the Issuer's Obligations. In the
event (i) that the Issuer delivers to the Trustee, in form and substance
acceptable to it, an Officers' Certificate and Opinion of Counsel certifying
that all the obligations under this Indenture, the Notes and the Security
Documents have been satisfied and discharged by the payment in full of the
Issuer's obligations under the Notes, this Indenture and the Security Documents,
and all such obligations have been so satisfied, or (ii) a discharge, legal
defeasance or covenant defeasance of this Indenture occurs under Article 8 or 12
(provided that in the case of this clause (ii), no Notes are then outstanding),
the Trustee shall deliver to the Issuer and the Second Lien Agent a notice
stating that the Trustee, on behalf of the Holders, disclaims and gives up any
and all rights it has in or to the Collateral, and any rights it has under the
Security Documents, and upon receipt by the Collateral Agent of such notice, the
Second Lien Agent shall be deemed not to hold a Lien in the Collateral on behalf
of the Trustee and shall do or cause to be done all acts reasonably necessary to
release such Lien as soon as is reasonably practicable.

      SECTION 10.08 Designations. Except as provided in the next sentence, for
purposes of the provisions hereof and the Intercreditor Agreement requiring the
Issuer to designate Indebtedness for the purposes of the terms First Priority
Lien Obligations and Other Second-Lien Obligations or any other such
designations hereunder or under the Intercreditor Agreement, any such
designation shall be sufficient if the relevant designation provides in writing
that such First Priority Lien Obligations or Other Second-Lien Obligations are
permitted under this Indenture and is signed on behalf of the Issuer by an
Officer and delivered to the Trustee, the Second Lien Agent and the First Lien
Agent. For all purposes hereof and the Intercreditor Agreement, the Issuer
hereby designates the Obligations pursuant to the Credit Agreement as in effect
on the Issue Date as First Priority Lien Obligations.

                                      101


                                   ARTICLE 11
                                 NOTE GUARANTEES

      SECTION 11.01 Guarantee.

            (a) Subject to this Article 11, Parent and 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, the Security Documents or
      the obligations of the Issuer hereunder or thereunder, that:

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

                  (2) in case of any extension of time of payment or renewal of
            any Notes or any of such other obligations, that same will be
            promptly paid in full when due or performed in accordance with the
            terms of the extension or renewal, whether at stated maturity, by
            acceleration or otherwise.

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

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

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

                                      102


            (d) Parent and each Subsidiary Guarantor agrees that it will not be
      entitled to any right of subrogation in relation to the Holders in respect
      of any obligations guaranteed hereby until payment in full of all
      obligations guaranteed hereby. Parent and each Subsidiary Guarantor
      further agrees that, as between Parent and the Subsidiary Guarantors, on
      the one hand, and the Holders and the Trustee, on the other hand, (1) the
      maturity of the obligations guaranteed hereby may be accelerated as
      provided in Article 6 hereof for the purposes of this Note Guarantee,
      notwithstanding any stay, injunction or other prohibition preventing such
      acceleration in respect of the obligations guaranteed hereby, and (2) in
      the event of any declaration of acceleration of such obligations as
      provided in Article 6 hereof, such obligations (whether or not due and
      payable) will forthwith become due and payable by Parent and the
      Subsidiary Guarantors for the purpose of this Note Guarantee, in each case
      subject to any rescission of any such acceleration pursuant to Section
      6.04. Parent and the Subsidiary Guarantors will 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
      Note Guarantee.

      SECTION 11.02 Limitation on Guarantor Liability. Parent and each
Subsidiary Guarantor, and by its acceptance of Notes, each Holder, hereby
confirms that it is the intention of all such parties that the Note Guarantee of
Parent or 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 Note Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders, Parent and the Subsidiary Guarantors hereby
irrevocably agree that the obligations of Parent or such Subsidiary Guarantor
will be limited to the maximum amount that will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of Parent or such
Subsidiary Guarantor that are relevant under such laws, and after giving effect
to any collections from, rights to receive contribution from or payments made by
or on behalf of Parent or any other Subsidiary Guarantor in respect of the
obligations of Parent or such other Subsidiary Guarantor under this Article 11,
result in the obligations of Parent or such Subsidiary Guarantor under its Note
Guarantee not constituting a fraudulent transfer or conveyance.

      SECTION 11.03 Execution and Delivery of Note Guarantee. To evidence its
Note Guarantee set forth in Section 11.01 hereof, Parent and each Subsidiary
Guarantor hereby agrees that a notation of such Note Guarantee substantially in
the form attached as Exhibit E hereto will be endorsed by an Officer of Parent
or such Subsidiary Guarantor on each Note authenticated and delivered by the
Trustee and that this Indenture will be executed on behalf of Parent or such
Subsidiary Guarantor by one of its Officers.

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

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

                                      103


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

      In the event that any Subsidiary of Parent or other Person is required to
become a Subsidiary Guarantor pursuant to Section 4.20, Parent and the Issuer
will cause such Subsidiary or other Person to comply with the provisions of
Section 4.20 and this Article 11.

      SECTION 11.04 Subsidiary Guarantors May Consolidate, etc., on Certain
Terms. Except as otherwise provided in this Section 11.04, the Issuer and Parent
will not permit any Subsidiary Guarantor to consolidate or merge with or into
another Person (whether or not such Subsidiary Guarantor is the surviving
corporation) or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of its properties or assets, in one or more related
transactions to another Person, unless:

            (1) immediately after such transaction, no Default or Event of
      Default exists;

            (2) either

                  (a) (i) such Subsidiary Guarantor is the surviving entity or
            the Person formed by or surviving any such consolidation or merger
            (if other than such Subsidiary Guarantor) or to which such sale,
            assignment, transfer, conveyance or other disposition has been made
            is a corporation, partnership or limited liability company organized
            or existing under the laws of the jurisdiction under which such
            Subsidiary Guarantor was organized or under the laws the United
            States, any state of the United States or the District of Columbia
            and (ii) the Person formed by or surviving any such consolidation or
            merger (if other than such Subsidiary Guarantor) or the Person to
            which such sale, assignment, transfer, conveyance or other
            disposition has been made assumes all the obligations of such
            Subsidiary Guarantor under such Subsidiary Guarantor's Note
            Guarantee, this Indenture and the Security Documents, in each case
            pursuant to a supplemental indenture and other agreements reasonably
            satisfactory to the Trustee; or

                  (b) in the case of a Subsidiary Guarantor that has been
            disposed of in its entirety to another Person (other than to the
            Issuer or any Affiliate of the Issuer), whether through a merger,
            consolidation or sale of Capital Stock or assets, the Issuer
            delivers an Officers' Certificate to the Trustee to the effect that
            the Issuer will comply with its obligations under Section 4.10 in
            respect of such sale or other disposition; and

            (3) the Issuer delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that such consolidation, merger or
      transfer and such supplemental indenture (if any) complies with this
      Indenture.

      In case of any such consolidation, merger, sale or disposition and upon
the assumption by the successor Person, by supplemental indenture, executed and
delivered to the Trustee and substantially in the form of Exhibit F hereto, of
the Note Guarantee endorsed upon the Notes and the due and punctual performance

                                      104


of all of the covenants and conditions of this Indenture to be performed by the
Subsidiary Guarantor, such successor Person will 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 Note Guarantees to be endorsed upon all of the Notes
issuable hereunder which theretofore shall not have been signed by the Issuer
and delivered to the Trustee. All the Note Guarantees so issued will in all
respects have the same legal rank and benefit under this Indenture as the Note
Guarantees theretofore and thereafter issued in accordance with the terms of
this Indenture as though all of such Note Guarantees had been issued at the date
of the execution hereof.

      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 will prevent any consolidation or merger of a Subsidiary Guarantor with or
into Parent, the Issuer or another Subsidiary Guarantor, or will prevent any
sale or disposition of all or substantially all of the assets of a Subsidiary
Guarantor to Parent, the Issuer or another Subsidiary Guarantor.

      SECTION 11.05 Releases.

      The Note Guarantee of a Subsidiary Guarantor will be released, and such
Subsidiary Guarantor will be released from and relieved of all of its
obligations under its Note Guarantee and this Indenture:

      (1)   in connection with any sale, disposition or transfer of all or
            substantially all of the assets of that Subsidiary Guarantor
            (including by way of merger or consolidation) to a Person that is
            not (either before or after giving effect to such transaction)
            Parent, the Issuer or a Restricted Subsidiary of Parent, if the
            sale, disposition or transfer does not violate the first paragraph
            of Section 4.10;

      (2)   in connection with any sale, disposition or transfer of all of the
            Capital Stock of that Subsidiary Guarantor to a Person that is not
            (either before or after giving effect to such transaction) Parent,
            the Issuer or a Restricted Subsidiary of Parent, if the sale,
            disposition or transfer does not violate the first paragraph of
            Section 4.10;

      (3)   if the Issuer designates any Restricted Subsidiary that is a
            Subsidiary Guarantor to be an Unrestricted Subsidiary in accordance
            with the applicable provisions of this Indenture;

      (4)   upon Legal Defeasance in accordance with Article 8 hereof or
            satisfaction and discharge of this Indenture in accordance
            with Article 12 hereof; or

      (5)   at such time as such Subsidiary Guarantor does not have any
            Indebtedness outstanding that would have required such Subsidiary
            Guarantor to enter into a Note Guarantee pursuant to Section 4.19.

      Upon delivery by the Issuer to the Trustee of an Officers' Certificate and
an Opinion of Counsel to the effect that a release of a Subsidiary Guarantor in
accordance with this Section 11.05 is authorized or permitted by this Indenture,
the Trustee will, upon the request and at the expense of the Issuer, execute any

                                      105


documents reasonably requested by the Issuer in order to evidence the release of
such Subsidiary Guarantor from its obligations under its Note Guarantee and this
Indenture.

                                   ARTICLE 12
                           SATISFACTION AND DISCHARGE

      SECTION 12.01 Satisfaction and Discharge. This Indenture will be
discharged and will cease to be of further effect as to all Notes issued
hereunder when:

            (1) either

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

                  (b) all Notes that have not been delivered to the Trustee for
            cancellation have become due and payable by reason of the mailing of
            a notice of redemption or otherwise or will become due and payable
            within one year and Parent, the Issuer or any Subsidiary Guarantor
            has irrevocably deposited or caused to be deposited with the Trustee
            as trust funds in trust solely for the benefit of the Holders, cash
            in U.S. dollars, non-callable Government Securities, or a
            combination of cash in U.S. dollars and non-callable Government
            Securities, in amounts as will be sufficient, without consideration
            of any reinvestment of interest, to pay and discharge the entire
            Indebtedness (including all principal and interest) on the Notes not
            delivered to the Trustee for cancellation;

            (2) Parent, the Issuer or any Subsidiary Guarantor has paid or
      caused to be paid all sums payable by it under this Indenture; and

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

In addition, the Issuer must deliver an Officers' Certificate and an Opinion of
Counsel to the Trustee stating that all conditions precedent to satisfaction and
discharge have been satisfied. Upon satisfaction of the conditions set forth in
this Section 12.01, and the receipt of such Officers' Certificate and Opinion of
counsel, the Trustee, upon request and at the expense of the Issuer, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture.

      Notwithstanding the satisfaction and discharge of this Indenture, if money
has been deposited with the Trustee pursuant to subclause (b) of clause (1) of
this Section 12.01, the provisions of Sections 12.02 and 8.06 will survive. In
addition, nothing in this Section 12.01 will be deemed to discharge those
provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

                                      106


      SECTION 12.02 Application of Trust Money. Subject to the provisions of
Section 8.06 hereof, all money deposited with the Trustee pursuant to Section
12.01 hereof shall be held in trust and applied by it, in accordance with the
provisions of the Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Issuer acting as its own Paying Agent)
as the Trustee may determine, to the Persons entitled thereto, of the principal
(and premium, if any) and interest for whose payment such money has been
deposited with the Trustee; but such money need not be segregated from other
funds except to the extent required by law.

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

                                   ARTICLE 13
                                 MISCELLANEOUS

      SECTION 13.01 Trust Indenture Act Controls. If any provision of this
Indenture limits, qualifies or conflicts with the duties imposed by TIA ss.
318(c) (other than, prior to any qualification of this Indenture under the TIA,
the limitations, qualifications or conflicts set forth in Sections 9.03, 9.06
and 10.05), the imposed duties will control.

      SECTION 13.02 Notices. Any notice or communication by Parent, the Issuer,
any Subsidiary Guarantor or the Trustee to the others is duly given if in
writing and delivered in Person or mailed by first class mail (registered or
certified, return receipt requested), telex, telecopier or overnight air courier
guaranteeing next day delivery, to the others' address:

      If to the Trustee:

      Attn: Rick Prokosch

      Parent, the Issuer, any Subsidiary Guarantor or the Trustee, by notice to
the others, may designate additional or different addresses for subsequent
notices or communications.

      All notices and communications (other than those sent to Holders) will be
deemed to have been duly given: at the time delivered by hand, if personally
delivered; five Business Days after being deposited in the mail, postage
prepaid, if mailed, when answered back, if telexed; when receipt acknowledged,
if telecopied; and the next Business Day after timely delivery to the courier,
if sent by overnight air courier guaranteeing next day delivery.

      Any notice or communication to a Holder will be mailed by first class
mail, certified or registered, return receipt requested, or by overnight air
courier guaranteeing next day delivery to its address shown on the register kept
by the Registrar. Any notice or communication will also be so mailed to any
Person described in TIA ss. 313(c), to the extent required by the TIA. Failure
to mail a notice or communication to a Holder or any defect in it will not
affect its sufficiency with respect to other Holders.

      If a notice or communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

      If the Issuer mails a notice or communication to Holders, it will mail a
copy to the Trustee and each Agent at the same time.

      Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

      Where this Indenture provides for notice of any event to a Holder of a
Global Note, such notice shall be sufficiently given if given to the Depository
for such Note (or its designee), pursuant to the Applicable Procedures, not
later than the latest date (if any), and not earlier than the earliest date (if
any), prescribed for the giving of such notice.

      SECTION 13.03 Communication by Holders of Notes with Other Holders of
Notes. Holders may communicate pursuant to TIA ss. 312(b) with other Holders
with respect to their rights under this Indenture or the Notes. The Issuer, the
Trustee, the Registrar and anyone else shall have the protection of TIA ss.
312(c).

      SECTION 13.04 Certificate and Opinion as to Conditions Precedent. Upon any
request or application by the Issuer to the Trustee to take any action under

                                      108


this Indenture, the Issuer shall furnish to the Trustee (except that the Opinion
of Counsel referred to in Section 13.04(2) hereof shall not be required in
connection with the Authentication Order):

            (1) an Officers' Certificate in form and substance reasonably
      satisfactory to the Trustee (which must include the statements set forth
      in Section 13.05 hereof) stating that, in the opinion of the signers, all
      conditions precedent and covenants, if any, provided for in this Indenture
      relating to the proposed action have been satisfied; and

            (2) an Opinion of Counsel in form and substance reasonably
      satisfactory to the Trustee (which must include the statements set forth
      in Section 13.05 hereof) stating that, in the opinion of such counsel, all
      such conditions precedent and covenants have been satisfied.

      In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion as to such matters in one or several
documents.

      Any certificate or opinion of an Officer of Parent, the Issuer or any
Subsidiary Guarantor may be based, insofar as it relates to legal matters, upon
a certificate of opinion of, or representations by, counsel, unless such Officer
knows, or in the exercise of reasonable care should know, that the certificate
or opinion or representations with respect to the matters upon which his
certificate or opinion is based are erroneous. Any such certificate or Opinion
of Counsel may be based, and may state that it is so based, insofar as it
relates to factual matters, upon a certificate or opinion of, or representations
by, an Officer or Officers of Parent, the Issuer or such Subsidiary Guarantor
stating that the information with respect to such factual matters is in
possession of Parent, the Issuer or such Subsidiary Guarantor, unless such
counsel knows, or in the exercise of reasonable care should know, that the
certificate of opinion or representations with respect to such matters are
erroneous.

      Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

      SECTION 13.05 Statements Required in Certificate or Opinion. Each
certificate or opinion with respect to compliance with a condition or covenant
provided for in this Indenture (other than a certificate provided pursuant to
TIA ss. 314(a)(4)) must comply with the provisions of TIA ss. 314(e) and must
include:

            (1) a statement that the Person making such certificate or opinion
      has read such covenant or condition;

            (2) a brief statement as to the nature and scope of the examination
      or investigation upon which the statements or opinions contained in such
      certificate or opinion are based;

                                      109


            (3) a statement that, in the opinion of such Person, he or she has
      made such examination or investigation as is necessary to enable him or
      her to express an informed opinion as to whether or not such covenant or
      condition has been satisfied; and

            (4) a statement as to whether or not, in the opinion of such Person,
      such condition or covenant has been satisfied.

      SECTION 13.06 Rules by Trustee and Agents. The Trustee may make reasonable
rules for action by or at a meeting of Holders. The Registrar or Paying Agent
may make reasonable rules and set reasonable requirements for its functions.

      SECTION 13.07 No Personal Liability of Directors, Officers, Employees and
Stockholders. No director, officer, employee, incorporator or stockholder of
Parent, the Issuer or any Subsidiary Guarantor, as such, will have any liability
for any obligations of Parent, the Issuer or the Subsidiary Guarantors under the
Notes, this Indenture, the Note 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 issuance of the Notes. The waiver may not be
effective to waive liabilities under the federal securities laws.

      SECTION 13.08 Governing Law. THIS INDENTURE AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HERETO AND THERETO, INCLUDING THE INTERPRETATION, CONSTRUCTION,
VALIDITY AND ENFORCEABILITY THEREOF, SHALL BE GOVERNED BY AND SHALL BE
CONSTRUED, INTERPRETED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK (INCLUDING SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW).

      SECTION 13.09 No Adverse Interpretation of Other Agreements. This
Indenture may not be used to interpret any other indenture, loan or debt
agreement of Parent, the Issuer or their respective Subsidiaries or of any other
Person. Any such indenture, loan or debt agreement may not be used to interpret

the Notes is invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions will not in any way be affected or
impaired thereby.

      SECTION 13.12 Counterpart Originals. The parties may sign any number of
copies of this Indenture. Each signed copy will be an original, but all of them
together represent the same agreement.
