will be substantially in the form of Exhibits A1 and A2 hereto. The Notes may
have notations, legends or endorsements required by law, stock exchange rule or
usage. Each Note will be dated the date of its authentication. The Notes shall
be in denominations of $1,000 and integral multiples thereof.

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

      (b) Global Notes. Notes issued in global form will be substantially in the
form of Exhibits A1 or A2 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 A1
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.

      (c) Temporary Global Notes. Notes offered and sold in reliance on
Regulation S will be issued initially in the form of the Regulation S Temporary
Global Note, which will be deposited on behalf of the purchasers of the Notes
represented thereby with the Trustee, at its St. Paul office, as custodian for
the Depositary, and registered in the name of the Depositary or the nominee of
the Depositary for the accounts of designated agents holding on behalf of
Euroclear or Clearstream, duly executed by the Company and authenticated by the
Trustee as hereinafter provided. The Restricted Period will be terminated upon
the receipt by the Trustee of:

            (1) a written certificate from the Depositary, together with copies
      of certificates from Euroclear and Clearstream certifying that they have
      received certification of non-United States beneficial ownership of 100%
      of the aggregate principal amount of the Regulation S Temporary Global
      Note (except to the extent of any beneficial owners thereof who acquired
      an interest therein during the Restricted Period pursuant to another
      exemption from registration under the Securities Act and who will take
      delivery of a beneficial ownership interest in a 144A Global Note or an
      IAI Global Note bearing a Private Placement Legend, all as contemplated by
      Section 2.06(b) hereof); and

            (2) an Officers' Certificate from the Company.

<PAGE>

      Following the termination of the Restricted Period, beneficial interests
in the Regulation S Temporary Global Note will be exchanged for beneficial
interests in the Regulation S Permanent Global Note pursuant to the Applicable
Procedures. Simultaneously with the authentication of the Regulation S Permanent
Global Note, the Trustee will cancel the Regulation S Temporary Global Note. The
aggregate principal amount of the Regulation S Temporary Global Note and the
Regulation S Permanent Global Note may from time to time be increased or
decreased by adjustments made on the records of the Trustee and the Depositary
or its nominee, as the case may be, in connection with transfers of interest as
hereinafter provided.

            (3) 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 in the Regulation
      S Temporary Global Note and the Regulation S Permanent Global Note that
      are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

      At least one Officer must sign the Notes for the Company by manual or
facsimile signature.

      If an Officer whose signature is on a Note no longer holds that office at
the time a Note is authenticated, the Note 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, from time to time upon receipt of a written order of the
Company signed by two Officers (an "Authentication Order"), authenticate Notes
for original issue that may be validly issued under this Indenture, including
any Additional Notes up to the aggregate principal amount stated in paragraph 4
of the Notes. The aggregate principal amount of Notes outstanding at any time
may not exceed the aggregate principal amount of Notes authorized for issuance
by the Company pursuant to one or more Authentication Orders, except as provided
in Section 2.07 hereof.

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

Section 2.03 Registrar and Paying Agent.

      The Company 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
Company may appoint one or more co-registrars and one or more additional paying
agents. The term "Registrar" includes any co-registrar and the term "Paying
Agent" includes any additional paying agent. The Company may change any Paying
Agent or Registrar without notice to any Holder. The Company will notify the
Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

                                       35

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

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

Section 2.04 Paying Agent to Hold Money in Trust.

      The Company 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 or Liquidated Damages, if any, or interest on the Notes, and will notify
the Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent to
pay all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary) will have no further
liability for the money. If the Company or a Subsidiary 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 Company, 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 Company 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 Company 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 except as a whole by the Depositary to a nominee of the Depositary,
by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes if:

            (1) the Company delivers to the Trustee notice from the Depositary
      that it is unwilling or unable to continue to act as Depositary or that it
      is no longer a clearing agency registered under the Exchange Act and, in
      either case, a successor Depositary is not appointed by the Company within
      60 days after the date of such notice from the Depositary;

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

            (3) there has occurred and is continuing a Default or Event of
      Default with respect to the Notes.

                                       36
<PAGE>

      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) 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 Regulation S Temporary Global Note may not be
      made to a U.S. Person or for the account or benefit of a U.S. Person
      (other than an Initial Purchaser). Beneficial interests in any
      Unrestricted Global Note may be transferred to Persons who take delivery
      thereof in the form of a beneficial interest in an Unrestricted Global
      Note. No written orders or instructions shall be required to be delivered
      to the Registrar to effect the transfers described in this Section
      2.06(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:

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

                        (ii) instructions given in accordance with the
                  Applicable Procedures containing information regarding the
                  Participant account to be credited with such increase; or

                  Registrar containing information regarding the Person in 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 Regulation S
                  Temporary Global Note prior to (A) the expiration of the
                  Restricted Period and (B) the receipt by the Registrar of any
                  certificates required pursuant to Rule 903 under the
                  Securities Act. Upon consummation of an Exchange Offer by the

                  requirements of this Section 2.06(b)(2) shall be deemed to
                  have been satisfied upon receipt by the Registrar of the
                  instructions contained in the Letter of Transmittal delivered
                  by the Holder of such beneficial interests in the Restricted
                  Global Notes. Upon satisfaction of all of the requirements for

      beneficial interest in an Unrestricted Global Note if the exchange or
      transfer complies with the requirements of Section 2.06(b)(2) above and:

                  (A) such exchange or transfer is effected pursuant to the
            Exchange Offer in accordance with the Registration Rights Agreement

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

                                       47
<PAGE>

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

            (5) Neither the Registrar nor the Company 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.

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

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

            (8) 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 Company and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Note, the Company 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 Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

      Every replacement Note is an additional obligation of the Company and 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
as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Note; however, Notes held by the

                                       48
<PAGE>

Company or a Subsidiary of the Company 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 unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a protected purchaser.

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

      If the Paying Agent (other than the Company, a Subsidiary or an Affiliate
of any 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 the
Company or any Guarantor, or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
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 the Trustee knows are so
owned will be so disregarded.

Section 2.10 Temporary Notes.

      Until certificates representing Notes are ready for delivery, the Company
may prepare and the Trustee, upon receipt of an Authentication Order, will
authenticate temporary Notes. Temporary Notes will be substantially in the form
of certificated Notes but may have variations that the Company considers
appropriate for temporary Notes and as may be reasonably acceptable to the
Trustee. Without unreasonable delay, the Company 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 Company 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 destroy canceled Notes
(subject to the record retention requirement of the Exchange Act). Certification
of the destruction of all canceled Notes will be delivered to the Company. The
Company may not issue new Notes to replace Notes that it has paid or that have
been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

      If the Company defaults in a payment of interest 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 Company 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 Company will fix or cause to be fixed each such
special record date and payment date; provided that no such special record date
may

                                       49
<PAGE>

be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) 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.

Section 2.13 CUSIP Numbers.

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

Section 2.14 Issuance of Additional Notes.

      The Company shall be entitled, subject to its compliance with Sections
4.09 and 4.12, to issue up to $50 million in aggregate principal amount of
Additional Notes under this Indenture which shall have identical terms as the
Initial Notes, other than with respect to the date of issuance and issue price,
provided that the Additional Notes are fungible with the Initial Notes for U.S.
Federal Income tax purposes. The Initial Notes, any Additional Notes and all
Exchange Notes or Private Exchange Notes issued in exchange therefore shall be
treated as a single class for all purposes under this Indenture. With respect to
any Additional Notes, the Company shall set forth in a resolution of the Board
of Directors and Officers' Certificate, a copy of each which shall be delivered
to the Trustee, the following information:

      (a) the aggregate principal amount of such Additional Notes to be
authenticated and delivered pursuant to this Indenture;

      (b) the issue price, the issue date and the CUSIP number of such
Additional Notes; and

      (c) whether such Additional Notes shall be transfer restricted notes and
issued in the form of Initial Notes as set forth in Section 2.02 of this
Indenture or shall be issued in the form of Exchange Notes.

                            REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

      If the Company elects to redeem Notes pursuant to the optional redemption
provisions of Section 3.07 hereof, it 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; and

            (4) the redemption price.

                                       50
<PAGE>

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 on a pro rata basis except:

            (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 otherwise required by law.

      In the event of partial redemption or purchase by lot, 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 Company 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; except that if all of the Notes of a Holder are to be
redeemed or purchased, the entire outstanding amount of Notes held by such
Holder, even if not a multiple of $1,000, shall be redeemed or purchased. 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 Company 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 hereof.

      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;

            (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 Company defaults in making such redemption
      payment, interest on Notes called for redemption ceases to accrue on and
      after the redemption date;

                                       51
<PAGE>

            (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 Company's request, the Trustee will give the notice of redemption
in the Company's name and at its expense; provided, however, that the Company
has delivered to the Trustee, at least 45 days prior to the redemption date, an
Officers' Certificate requesting that the Trustee give such notice and setting
forth the information to be stated in such notice as provided in the preceding
paragraph.

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 stated in the 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 Company
will deposit with the Trustee or with the Paying Agent money sufficient to pay
the redemption or purchase price of and accrued interest and Liquidated Damages,
if any, on all Notes to be redeemed or purchased on that date. The Trustee or
the Paying Agent will promptly return to the Company any money deposited with
the Trustee or the Paying Agent by the Company in excess of the amounts
necessary to pay the redemption or purchase price of, and accrued interest and
Liquidated Damages, if any, on, all Notes to be redeemed or purchased.

      If the Company 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 Company 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
Company will issue and, upon receipt of an Authentication Order, the Trustee
will authenticate for the Holder at the expense of the Company 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, 2007, the Company may on any one or more
occasions redeem up to 35% of the aggregate principal amount of Notes issued
under this Indenture at a redemption price of 111.5% of the principal amount
thereof, plus accrued and unpaid interest and Liquidated Damages, if any, to the
redemption date, with the net cash proceeds one or more Qualified Equity
Issuances; provided that:

                                       52
<PAGE>

            (1) at least 65% of the aggregate principal amount of Notes
      originally issued under this Indenture (excluding Notes held by the
      Company and its Subsidiaries) remains outstanding immediately after the
      occurrence of such redemption; and

            (2) the redemption occurs within 90 days of the date of the closing
      of such Qualified Equity Issuances.

      (b) The Company may also at its option on any one or more occasions redeem
all or part of the Notes upon not less than 30 nor more than 60 days prior
notice, at a redemption price equal to 100% of the principal amount thereof plus
the Applicable Premium as of the date of redemption (the "Make-Whole Redemption
Date"). Notices of redemption may be conditional.

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

Section 3.08 Mandatory Redemption.

      Other than as set forth in Section 3.11, the Company is not required to
make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

      In the event that, pursuant to Section 4.10(c) hereof, the Company is
required to commence an offer to all Holders to purchase Notes (an "Asset Sale
Offer"), it will follow the procedures specified below.

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

      If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued and unpaid interest and
Liquidated Damages, if any, 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 Asset Sale
Offer.

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

            (1) that the Asset Sale Offer is being made pursuant to this Section
      3.09 and Section 4.10(c) hereof and the length of time the Asset Sale
      Offer 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 accrete or accrue interest;

                                       53
<PAGE>

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

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

            (6) that Holders electing to have Notes purchased pursuant to any
      Asset Sale Offer 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 Company, a
      Depositary, if appointed by the Company, 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
      Company, 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 surrendered by
      Holders thereof exceeds the Offer Amount, the Company will select the
      Notes to be purchased on a pro rata basis based on the principal amount of
      Notes surrendered (with such adjustments as may be deemed appropriate by
      the Company so that only Notes in denominations of $1,000, or integral
      multiples 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 Company 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 Asset Sale Offer,
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 Company in accordance with the terms of
this Section 3.09. The Company, the Depositary or the Paying Agent, as the case
may be, will promptly (but in any case not later than five 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 Company
for purchase, and the Company will promptly issue a new Note, and the Trustee,
upon written request from the Company, 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 Company to the
Holder thereof. The Company will publicly announce the results of the Asset Sale
Offer on the Purchase Date.

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

Section 3.10 Offer to Purchase by Application of Collateral Proceeds.

                                       54
<PAGE>

      In the event that, pursuant to Section 4.10(f) hereof, the Company is
required to commence an offer to all Holders to purchase Notes (a "Collateral
Proceeds Offer"), it will follow the procedures specified below.

      The Collateral Proceeds Offer shall be made to all Holders. The Collateral
Proceeds Offer will remain open for a period of 20 Business Days following its
commencement and no longer except to the extent that a longer period is required
by applicable law (the "Collateral Offer Period"). No later than five Business
Days after termination of the Collateral Offer Period (the "Collateral Purchase
Date"), the Company will apply all Excess Collateral Proceeds (the "Collateral
Offer Amount") to the purchase of Notes or, if less than the Collateral Offer
Amount has been tendered, all Notes tendered in response to the Collateral
Proceeds Offer. Payment for any Notes so purchased will be made in the same
manner as interest payments are made.

      If the Collateral Purchase Date is on or after an interest record date and
on or before the related interest payment date, any accrued and unpaid interest
and Liquidated Damages, if any, 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 Collateral
Proceeds Offer.

      Upon the commencement of Collateral Proceeds Offer, the Company will send,
by first class mail, a notice to the Trustee and each of the Holders, with a
copy to the Trustee. The notice will contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Collateral
Proceeds Offer. The notice, which will govern the terms of the Collateral
Proceeds Offer, will state:

            (1) that the Collateral Proceeds Offer is being made pursuant to
      this Section 3.10 and Section 4.10(f) hereof and the length of time the
      Collateral Proceeds Offer will remain open;

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

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

            (4) that, unless the Company defaults in making such payment, any
      Note accepted for payment pursuant to the Collateral Proceeds Offer will
      cease to accrete or accrue interest after the Collateral Purchase Date;

            (5) that Holders electing to have a Note purchased pursuant to a
      Collateral Proceeds Offer may elect to have Notes purchased in integral
      multiples of $1,000 only;

            (6) that Holders electing to have Notes purchased pursuant to any
      Collateral Proceeds Offer 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 Company, a
      Depositary, if appointed by the Company, or a Paying Agent at the address
      specified in the notice at least three days before the Collateral Purchase
      Date;

            (7) that Holders will be entitled to withdraw their election if the
      Company, 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;

                                       55
<PAGE>

            (8) that, if the aggregate principal amount of Notes surrendered by
      Holders thereof exceeds the Offer Amount, the Company will select the
      Notes to be purchased on a pro rata basis based on the principal amount of
      Notes surrendered (with such adjustments as may be deemed appropriate by
      the Company so that only Notes in denominations of $1,000, or integral
      multiples 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 Collateral Purchase Date, the Company 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 Collateral
Proceeds Offer, 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 Company in accordance with
the terms of this Section 3.10. The Company, the Depositary or the Paying Agent,

      The Company shall pay or cause to be paid the principal of, premium, if
any, and interest and Liquidated Damages, if any, on, the Notes on the dates and
in the manner provided in the Notes. Principal, premium, if any, and interest
and Liquidated Damages, if any, shall be considered paid on the date due if the
Paying Agent, if other than the Company or a Subsidiary thereof, holds as of

shall pay all Liquidated Damages, if any, in the same manner on the dates and in

      The Company shall 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 shall pay interest (including post-petition interest in any

Section 4.02 Maintenance of Office or Agency.

      The Company shall maintain in the City of St. Paul, Minnesota, an office

Registrar or co-registrar) where Notes may be surrendered for registration of
transfer or for exchange and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company shall 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 Company fails to maintain
any such required office or agency or fails to furnish the Trustee with the

or served at the Corporate Trust Office of the Trustee.

      The Company may also from time to time designate one or more other offices
or agencies where the Notes may be presented or surrendered for any or all such
purposes and may from time to time rescind such designations; provided, however,
that no such designation or rescission shall in any manner relieve the Company
of its obligation to maintain an office or agency in the City of St. Paul,
Minnesota, for such purposes. The Company shall 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.

one such office or agency of the Company in accordance with Section 2.03 hereof.

with the SEC.

      (d) In addition, the Company and the Guarantors agree that, for so long as
any Notes remain outstanding, at any time they are not required to file the
reports required by the preceding paragraphs of this Section 4.03 with the SEC,
they shall furnish to the Holders and to securities analysts and prospective
investors, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

the end of each fiscal year, an Officers' Certificate stating that a review of
the activities of the Company and its Subsidiaries during the preceding fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture and the other Senior Secured Note Documents,
and further stating, as to each such Officer signing such certificate, that to
the best of his or her knowledge the Company has kept, observed, performed and
fulfilled each and every covenant contained in this Indenture and the other

the other Senior Secured Note Documents (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 Company is taking or proposes to take
with respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action the Company is taking
or proposes to take with respect thereto.

      (b) So long as any of the Notes are outstanding, the Company shall deliver
to the Trustee, forthwith upon any Officer becoming aware of any Default or
Event of Default, an Officers' Certificate specifying such Default or Event of
Default and what action the Company is taking or proposes to take with respect
thereto.

Section 4.05 Taxes.

      The Company shall pay, and shall cause each of the Guarantors 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.

Section 4.06 Stay, Extension and Usury Laws.

      The Company and each of the Guarantors covenants (to the extent that it
may lawfully do so) that it shall not at any time insist upon, plead, or in any

                                       58

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 the Company and each of the 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 shall not, by resort to any such law, hinder,
delay or impede the execution of any power herein granted to the Trustee, but
shall suffer and permit the execution of every such power as though no such law
has been enacted.

Section 4.07   Restricted Payments.

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

            (1) declare or pay any dividend or make any other payment or

      between or among the Company and any of its Restricted Subsidiaries)
      except a payment of interest or principal at or within one year of 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:

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

            (2) the Company would, at the time of such Restricted Payment, after
      giving pro forma effect thereto as if such Restricted Payment had been
      made at the beginning of the applicable four-quarter period, have been
      permitted to incur at least $1.00 of additional Indebtedness pursuant to
      Section 4.09(a) and

            (3) such Restricted Payment, together with the aggregate amount of
      all other Restricted Payments made by the Company and its Restricted

            the end of the Company's most recently ended fiscal quarter for
            which internal financial statements are available at the time of
            such Restricted Payment (or, if such Consolidated Net Income for
            such period is a deficit, less 100% of such deficit), plus

                  (B) 100% of the aggregate net cash proceeds received by the

            (1) the payment of any dividend or similar distribution or the
      consummation of any redemption within 60 days after the date of
      declaration of the dividend or distribution or the giving of the

      contribution of common equity capital to the Company; provided that the
      amount of any such Restricted Payment made shall be excluded from clause
      (3)(B) of Section 4.07(a);

      materially affect the Company's ability to make principal or interest
      payments on the Notes and (b) the encumbrance or restriction is not
      materially less favorable to the Holders of the Notes than is customary in
      comparable financings or agreements (as determined by the Board of

      Indebtedness or Capital Stock was incurred in connection with or in
      contemplation of such acquisition), which encumbrance or restriction is
      not applicable to any Person, or the properties or assets of any Person,
      other than the Person, or the property or assets of the Person, so

            (10) Permitted Refinancing Indebtedness, provided that the
      restrictions contained in the agreements governing such Permitted
      Refinancing Indebtedness are not materially more restrictive, taken as a

      being refinanced, as determined in good faith by the Board of Directors of
      the Company;

            (11) Liens securing Indebtedness that limit the right of the debtor

Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt), and the Company shall not issue any Disqualified Stock and shall not
permit any of its Restricted Subsidiaries to issue any shares of preferred
stock; provided, however, that the Company may incur Indebtedness (including
Acquired Debt) or issue Disqualified Stock, and the Guarantors may incur
Indebtedness (including Acquired Debt) or issue preferred stock, in each case if
the Fixed Charge Coverage Ratio for the Company'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 preferred stock is issued would have been at least
2.0 to 1, determined on a pro forma basis (including a pro forma application of
the net proceeds therefrom), as if the additional Indebtedness had been incurred
or the preferred stock or Disqualified Stock had been issued, as the case may
be, at the beginning of such four-quarter period.

      (b) The provisions of Section 4.09(a) hereof shall not prohibit the
incurrence of any of the following items of Indebtedness (collectively,

            Indebtedness, such Indebtedness must be expressly subordinated to
            the prior payment in full in cash of all Obligations with respect to

            to a Person that is not either the Company or a Restricted
            Subsidiary of the Company shall be deemed, in each case, to

            this clause (7);

            (8) prior to the expiration of the Escrow Period, the incurrence by

      business, provided that such Indebtedness is extinguished within five
      Business Days of its incurrence;

      principal amount at any one time outstanding under this clause (16) not to

            (17) the incurrence by Foreign Restricted Subsidiaries of
      Indebtedness in an aggregate principal amount, at any time outstanding,

      refinance or replace any Indebtedness incurred pursuant to this clause
      (17), not to exceed $5.0 million; and

      Subsidiaries of additional unsecured Indebtedness in an aggregate
      principal amount (or accreted value, as applicable) at any

                                       65
<PAGE>

      time outstanding, including all Permitted Refinancing Indebtedness
      incurred to refund, refinance or replace any Indebtedness incurred
      pursuant to this clause (18), not to exceed $25.0 million; provided that
      Restricted Subsidiaries that are not Guarantors may not incur
      Indebtedness, when taken together with any Indebtedness issued and
      outstanding under clause (17) of this Section 4.09(b), in excess of $8.0
      million in the aggregate pursuant to this clause (18).

      To the extent the Company's Unrestricted Subsidiaries incur Non-Recourse
Indebtedness and any such Indebtedness ceases to be Non-Recourse Indebtedness,
then such event shall be deemed to constitute an incurrence of Indebtedness by a
Restricted Subsidiary of the Company that was subject to this Section 4.09.

      The Company and the Guarantors shall not incur any Indebtedness (including
Permitted Debt) that is contractually subordinated in right of payment to any
other Indebtedness of the Company or any Guarantor unless such Indebtedness is
also contractually subordinated in right of payment to the Notes on
substantially identical terms; provided, however, that no Indebtedness of the
Company or any Guarantor shall be deemed to be contractually subordinated in
right of payment to any other Indebtedness of the Company or any Guarantor
solely by virtue of being unsecured or by virtue of being secured on a first or
junior Lien basis.

      For purposes of determining compliance with this Section 4.09, in the
event that an item of proposed Indebtedness meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (18) above,
or is entitled to be incurred pursuant to Section 4.09(a), the Company shall be
permitted to divide and classify such item of Indebtedness on the date of its
incurrence or later reclassify all or a portion of such item of Indebtedness in
any manner that complies with this Section 4.09. Indebtedness under Credit
Facilities outstanding on the date on which Notes are first issued and
authenticated under this Indenture shall be deemed to have been incurred on such
date in reliance on the exception provided by clause (8) of the definition of
Permitted Debt. Indebtedness under Credit Facilities outstanding on the
expiration date of the Escrow Period shall be deemed to have been incurred on
such date in reliance on the exception provided by clause (1) or (2) of the
definition of Permitted Debt, as applicable. The accrual of interest, the
accretion 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 stock as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock in the
form of additional shares of the same class of Disqualified Stock shall not be
deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock
for purposes of this covenant; provided, in each such case, that the amount of
any such accrual, accretion or payment is included in Fixed Charges of the
Company as accrued.

      The amount of any Indebtedness outstanding as of any date shall be:

            (1) the accreted value of the Indebtedness, in the case of any
      Indebtedness issued with original issue discount;

            (2) the principal amount of the Indebtedness, in the case of any
      other Indebtedness; and

            (3) in respect of Indebtedness of another Person secured by a Lien
      on the assets of the specified Person, the lesser of:

                  (a) the fair market value of such assets at the date of
            determination; and

                  (b) the amount of the Indebtedness of the other Person.

                                       66
<PAGE>

      For purposes of determining compliance with any U.S. dollar denominated
restriction on the incurrence of Indebtedness where the Indebtedness incurred is
denominated in a currency other than U.S. dollars, the amount of such
Indebtedness shall be the U.S. Dollar Equivalent of such Indebtedness determined
on the date of incurrence, provided that if any such Indebtedness denominated in
a currency other than U.S. dollars is subject to a Currency Agreement with
respect to U.S. dollars covering all principal, premium, if any, and interest
payable on such Indebtedness, the amount of such Indebtedness expressed in U.S.
dollars shall be as provided in such Currency Agreement. The principal amount of
any Permitted Refinancing Indebtedness incurred in the same currency as the
Indebtedness being refinanced shall be the U.S. Dollar Equivalent of the
Indebtedness being refinanced, except to the extent that (a) such U.S. Dollar
Equivalent was determined based on a Currency Agreement, in which case the
Permitted Refinancing Indebtedness shall be determined in accordance with the
preceding sentence, and (b) the principal amount of the Permitted Refinancing
Indebtedness exceeds the principal amount of the Indebtedness being refinanced,
in which case the U.S. Dollar Equivalent of such excess shall be determined on
the date such Permitted Refinancing Indebtedness is incurred.

Section 4.10 Asset Sales.

      (a) The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale (including a Sale of Senior Secured
Note Priority Collateral) unless:

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

            (2) if such Asset Sale, in any single transaction or series of
      related transactions, involves assets having a fair market value of
      greater than $15.0 million, such fair market value is determined by the
      Company's Board of Directors and evidenced by a resolution of the Board of
      Directors set forth in an Officers' Certificate delivered to the Trustee;

            (3) in the case of a Sale of Senior Secured Note Priority
      Collateral, the Collateral Agent is promptly granted a perfected first
      priority security interest (subject to Permitted Prior Liens) in the Net
      Collateral Proceeds therefor received by the Company or the Restricted
      Subsidiary as additional Senior Secured Note Priority Collateral under the
      Security Documents to secure the Senior Secured Note Obligations, and, in
      the case of cash or Cash Equivalents constituting Net Collateral Proceeds,
      such Net Collateral Proceeds must be deposited into a segregated account
      under the sole control of the Collateral Agent that includes only proceeds
      from the Sale of Senior Secured Note Priority Collateral and interest
      earned thereon (an "Asset Sale Proceeds Account") and is free from all
      other Liens (other than Permitted Prior Liens), all on terms and pursuant
      to arrangements reasonably satisfactory to the Collateral Agent in its
      reasonable determination (which may include, at the Collateral Agent's
      reasonable request, customary officers' certificates and legal opinions
      and shall include release provisions requiring the Collateral Agent to
      release deposits in the Asset Sale Proceeds Account as necessary to permit
      the Company or its Restricted Subsidiaries to apply such Net Collateral
      Proceeds in the manner described below, unless the Collateral Agent has
      received written notice that an Event of Default has occurred and is
      continuing); and

            (4) at least 75% of the consideration received in the Asset Sale by
      the Company or such Restricted Subsidiary is in the form of cash and Cash
      Equivalents. For purposes of this Section 4.10, each of the following
      shall be deemed to be cash:

                                       67
<PAGE>

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

                  (B) any securities, notes or other obligations received by the
            Company or any such Restricted Subsidiary from such transferee that
            are converted by the Company or such Restricted Subsidiary within 45
            days of receipt into cash or Cash Equivalents, to the extent of the
            cash or Cash Equivalents received in that conversion.

      (b) Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, other than a Sale of Senior Secured Note Priority Collateral, the Company
may apply such Net Proceeds to:

            (1) repay Indebtedness and other Obligations under a Credit Facility
      and, if the Indebtedness repaid is revolving credit Indebtedness, to
      correspondingly reduce commitments with respect thereto;

            (2) acquire (or enter into a binding agreement to acquire, provided
      that such commitment shall be subject only to customary conditions (other
      than financing) and such acquisition shall be consummated within 180 days
      after the end of such 365 day period) all or substantially all of the
      assets of, or a majority of the Voting Stock of, a Permitted Business or
      the minority interest in any Restricted Subsidiary;

            (3) make a capital expenditure;

            (4) acquire (or enter into a binding agreement to acquire, provided
      that such commitment shall be subject only to customary conditions (other
      than financing) and such acquisition shall be consummated within 180 days
      after the end of such 365 day period) other long-term assets that are used
      or useful in a Permitted Business; or

            (5) make an offer to all Holders of Notes to purchase Notes at a
      purchase price equal to 100% of the principal amount of the Notes to be
      purchased plus accrued and unpaid interest and Liquidated Damages, if any,
      to the date of purchase, payable in cash.

Pending the final application of any Net Proceeds from Asset Sales, other than a
Sale of Senior Secured Note Priority Collateral, the Company may temporarily
reduce revolving credit borrowings or otherwise invest such Net Proceeds in any
manner that is not prohibited by this Indenture.

      (c) Any Net Proceeds from Asset Sales, other than a Sale of Senior Secured
Note Priority Collateral, that are not applied or invested as provided in
Section 4.10(b) shall constitute "Excess Proceeds." When the aggregate amount of
Excess Proceeds exceeds $10.0 million, the Company shall within five Business
Days make an Asset Sale Offer to all Holders of Notes with the proceeds of sales
of assets to purchase the maximum amount of Notes that may be purchased out of
the Excess Proceeds.

      (d) The offer price in any Asset Sale Offer shall be equal to 100% of the
principal amount of the Notes to be purchased plus accrued and unpaid interest
and Liquidated Damages, if any, to the date of purchase, and shall be payable in
cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer,
the Company may use those Excess Proceeds for any purpose not otherwise
prohibited by this Indenture. If the aggregate principal amount of Notes
tendered into such Asset Sale Offer exceeds the

                                       68
<PAGE>

amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on
a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero.

      (e) Within 365 days after the receipt of any Net Collateral Proceeds from
a Sale of Senior Secured Note Priority Collateral, the Company or the Restricted
Subsidiary, as the case may be, may apply such Net Collateral Proceeds (other
than any non-cash consideration representing Permitted Assets received by the
Company in respect of any Sale of Senior Secured Note Priority Collateral;
provided that the Collateral Agent shall promptly be granted a perfected first
priority security interest (subject to Permitted Prior Liens) on all such assets
as Senior Secured Note Priority Collateral under the Security Documents to
secure the Notes on terms and pursuant to arrangements reasonably satisfactory
to the Collateral Agent in its reasonable determination (which may include, at
the Collateral Agent's reasonable request, customary officers' certificates and
legal opinions)) at its option:

            (1) to acquire (or enter into a binding agreement to acquire,
      provided that such commitment shall be subject only to customary
      conditions (other than financing) and shall be consummated within 180 days
      after the end of such 365 day period) all or substantially all of the
      assets of, or a majority of the Voting Stock of, a Permitted Business
      principally owning Permitted Assets that have (in the good faith judgment
      of the Company) a value, net of the value of any Credit Facility Priority
      Collateral included therein, at least equal to the amount of such Net
      Collateral Proceeds; or

            (2) to make capital expenditures on or acquire (or enter into a
      binding agreement to acquire, provided that such commitment shall be
      subject only to customary conditions (other than financing) and shall be
      consummated within 180 days after the end of such 365 day period)
      Permitted Assets;

provided, that in each such case, the Collateral Agent shall immediately be
granted a perfected first priority security interest (subject to Permitted Prior
Liens) on all of the assets (other than any Credit Facility Priority Collateral
included therein) acquired with such Net Collateral Proceeds as Senior Secured
Note Priority Collateral under the Security Documents to secure the Senior
Secured Note Obligations, all on terms and pursuant to arrangements reasonably
satisfactory to the Collateral Agent in its reasonable determination (which may
include, at the Collateral Agent's reasonable request, customary officers'
certificates and legal opinions).

      (f) Any Net Collateral Proceeds from any Sale of Senior Secured Note
Priority Collateral that are not applied or invested as provided in Section
4.10(e) shall constitute "Excess Collateral Proceeds." When the aggregate amount
of Excess Collateral Proceeds exceeds $10.0 million, the Company shall within
five Business Days make an offer to all Holders of Notes (a "Collateral Proceeds
Offer") with the proceeds of sales of assets to purchase the maximum principal
amount of Notes that may be purchased out of the Excess Collateral Proceeds. The
offer price in any Collateral Proceeds Offer shall be equal to 100% of principal
amount plus accrued and unpaid interest and Liquidated Damages, if any, to the
date of purchase, and shall be payable in cash. If any Excess Collateral
Proceeds remain after consummation of a Collateral Proceeds Offer, the Company
and its Restricted Subsidiaries may use any remaining Excess Collateral
Proceeds, free and clear of any Liens created by any Security Documents or
otherwise for the benefit of any Holder of Senior Secured Note Obligations, for
any other purpose not otherwise prohibited by this Indenture. If the aggregate
principal amount of Notes tendered into such Collateral Proceeds Offer exceeds
the amount of Excess Collateral Proceeds, the Trustee shall select the Notes to
be purchased on a pro rata basis. Upon completion of each Collateral Proceeds
Offer, the amount of Excess Collateral Proceeds shall be reset at zero.

                                       69
<PAGE>

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

Section 4.11 Transactions with Affiliates.

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

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

            (2) the Company delivers to the trustee:

                  (A) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $5.0 million, a resolution of the Board of Directors of
            the Company set forth in an Officers' Certificate certifying that
            such Affiliate Transaction complies with this Section 4.11 and that
            such Affiliate Transaction has been approved by a majority of the
            disinterested members of the Board of Directors; and

                  (B) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $15.0 million, an opinion issued by an accounting,
            appraisal or investment banking firm of national standing as to the
            fairness to the Company of such Affiliate Transaction from a
            financial point of view or that such Affiliate Transaction is not
            materially less favorable to the Company and its Restricted
            Subsidiaries than would reasonably be expected to be obtained in a
            comparable transaction by the Company or such Restricted Subsidiary
            with an unrelated Person.

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

            (1) any employment agreement entered into by the Company or any of
      its Restricted Subsidiaries in the ordinary course of business of the
      Company or such Restricted Subsidiary;

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

            (3) transactions with a Person (other than an Unrestricted
      Subsidiary of the Company) that is an Affiliate of the Company solely
      because the Company owns, directly or through a Restricted Subsidiary, an
      Equity Interest in, or controls, such Person;

            (4) payment of reasonable directors fees;

                                       70

Secured Note Obligations and (2) causes such Lien to be duly perfected.

Section 4.15 Offer to Repurchase Upon Change of Control.

      (a) Upon the occurrence of a Change of Control, the Company shall 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) of that Holder's Notes
validly tendered in the Change of Control Offer at a purchase price in cash
equal to 101% of the aggregate principal amount of Notes repurchased plus
accrued and unpaid interest and Liquidated Damages, if any, on the Notes
repurchased to the date of purchase, subject to the rights of 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 Company shall mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and stating:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.15 and that all Notes tendered shall 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 shall continue to accrue interest;

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

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

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

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

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

                                       72
<PAGE>

            (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 Company.

      The Paying Agent shall promptly mail (but in any case not later than five
days after the Change of Control Payment Date) to each Holder of Notes properly
tendered the Change of Control Payment for such Notes, and the Trustee shall
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that any new Note shall be in a
principal amount of $1,000 or an integral multiple of $1,000. The Company shall
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

      (c) Notwithstanding anything to the contrary in this Section 4.15, the
Company shall not be required to make a Change of Control Offer upon a Change of
Control if (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 hereof, unless and until there is a default in payment of the
applicable redemption price.

Section 4.16   Limitation on Sale and Leaseback Transactions.

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

            (1) the Company 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 any provision of
      Section 4.09 hereof and (b) incurred a Lien to secure such Indebtedness
      pursuant to 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 and set forth in an Officers' Certificate
      delivered to the Trustee if such gross cash proceeds are more than $10.0
      million, 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, if such transfer is an Asset Sale, the Company applies
      the proceeds of such transaction in compliance with Section 4.10 hereof.

Section 4.17 Payments for Consent.

      The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any Holder of Notes for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Notes unless such consideration is offered to be paid
and is paid to all Holders of the Notes that

                                       73
<PAGE>

consent, waive or agree to amend in the time frame set forth in the solicitation
documents relating to such consent, waiver or agreement.

Section 4.18 Additional Guarantees and Liens.

      (a) If the Company or any of its Restricted Subsidiaries acquires or
creates another Domestic Restricted Subsidiary after the date of this Indenture
(except for Subsidiaries that have properly been designated as Unrestricted
Subsidiaries in accordance with this Indenture for so long as they continue to
constitute Unrestricted Subsidiaries) or any other Restricted Subsidiary
guarantees or otherwise provides direct credit support for any Indebtedness of
the Company or any Guarantor, then that Restricted Subsidiary (other than a
Receivables Subsidiary) shall (1) execute a supplemental indenture and a joinder
agreement to the Security Documents in form and substance reasonably
satisfactory to the Trustee providing that such Restricted Subsidiary shall
become a Guarantor under this Indenture and a party to the Security Documents
and (2) deliver an Opinion of Counsel to the effect that such supplemental
indenture and joinder agreement has been duly authorized and executed by such
Restricted Subsidiary, in each case, within 10 Business Days following the date
on which it was acquired or created; provided that any Domestic Restricted
Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor
until such time as it ceases to be an Immaterial Subsidiary. The form of such
Note Guarantee is attached as Exhibit E hereto.

      (b) If the Company or any of the Guarantors at any time (1) owns or
acquires Senior Secured Note Priority Collateral that is not subject to a valid,
enforceable perfected first priority Lien (subject to Permitted Prior Liens) in
favor of the Collateral Agent as security for the Senior Secured Note
Obligations or (2) grants, assumes or becomes subject to any Lien upon any of
its property that constitutes Credit Facility Priority Collateral as security
for any Credit Facility Obligation, then the Company shall, or shall cause such
Guarantor to, concurrently:

                  (A) execute and deliver to the Collateral Agent a security
            document upon substantially the same terms as the Security Documents
            delivered in connection with the issuance of the Notes, granting, in
            the case of any Senior Secured Note Priority Collateral, a first
            priority Lien upon such Senior Secured Note Priority Collateral or,
            in the case of any Credit Facility Priority Collateral, a second
            priority Lien upon such Credit Facility Priority Collateral, in
            either case, in favor of the Collateral Agent for the benefit of the
            Holders of the Senior Secured Note Obligations; and

                  (B) cause any such Lien granted in such security document to
            be duly perfected in any manner permitted by law and, in the case of
            any Senior Secured Note Priority Collateral, cause each other Lien
            upon such Senior Secured Note Priority Collateral to be (1)
            released, unless it is a Permitted Lien or (2) subordinated to the
            Senior Secured Note Liens if it is a Permitted Lien but not a
            Permitted Prior Lien.

Section 4.19 Designation of Restricted and Unrestricted Subsidiaries.

      The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause
a Default, provided, that in no event may the Board of Directors designate any
(a) Restricted Subsidiary that holds assets constituting Senior Secured Note
Priority Collateral having a fair value of greater than $5.0 million or (b)
group of Restricted Subsidiaries that together hold assets constituting Senior
Secured Note Priority Collateral having a fair value of greater than $5.0
million, to be an Unrestricted Subsidiary or Unrestricted Subsidiaries, as the
case may be. If a Restricted Subsidiary is designated as an Unrestricted
Subsidiary, the aggregate fair market value of all outstanding Investments owned
by the Company and its Restricted Subsidiaries in the

                                       74
<PAGE>

Subsidiary properly designated shall be deemed to be an Investment made as of
the time of the designation and shall reduce the amount available for Restricted
Payments under Section 4.07(a) or Permitted Investments, as determined by the
Company. That designation shall only be permitted if the Investment would be
permitted at that time and if the Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. The Board of Directors of the Company
may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the
redesignation would not cause a Default.

Section 4.20 Escrow Account Deposits

      Upon consummation of the sale of the Initial Notes, the Company shall
deposit the gross proceeds of the Notes offering into the Escrow Account with
the Escrow Agent.

Section 4.21 Activities of the Company Prior to the Escrow Merger

      Prior to the Escrow Merger, the Company shall be a limited purpose
corporation whose primary activities are restricted in its certificate of
incorporation to issuing the Notes, issuing capital stock to, and receiving
capital contributions from, Milacron, performing its obligations with respect to
the Notes under this Indenture, the Escrow Agreement and the Registration Rights
Agreement, and consummating the Escrow Merger or redeeming the Notes on the
Escrow Redemption Date, as applicable, and conducting such other activities as
are necessary or appropriate to carry out the activities described above. Prior
to the Escrow Merger, the Company shall not own, hold or otherwise have any
interest in any assets other than the Escrow Account and, cash, Cash Equivalents
or Government Securities.

      Prior to the Escrow Merger, not less than two members of the Company's
Board of Directors (the "Independent Directors") shall be individuals who are
not, and never have been, direct, indirect or beneficial stockholders, officers,
directors, employees, affiliates, associates, material suppliers or material
customers of Milacron or any of its Affiliates, and the certificate of
incorporation of the Company shall provide that (1) at least two members of the
Company's Board of Directors shall be an Independent Director, (2) the Company's
Board of Directors shall not approve, or take any other action to cause the
filing of, a voluntary bankruptcy petition with respect to the Company without
the unanimous vote of the entire Board of Directors without any vacancies
(including the Independent Directors) and (3) the provisions requiring two
independent directors and the provision described in clauses (1) and (2) above
cannot be amended without the prior written consent of the Independent
Directors.

      Neither Independent Director shall at any time serve as a trustee in
bankruptcy for the Company or any Affiliate thereof. Any director, employee,
consultant or agent of the Company shall be compensated from the Company's funds
for services provided to the Company. The Company shall not engage any agents
(other than its attorneys, auditors and other professionals).

      The Company shall keep correct and complete books and records of account
and minutes of the meetings and other proceedings of its stockholder and board
of directors, as applicable, and the resolutions, agreements and other
instruments of the Company shall be continuously maintained as official records
by the Company.

      The Company shall strictly observe organizational formalities in its
dealings with Milacron and its Affiliates, and funds or other assets of the
Company shall not be commingled with those of any of its Affiliates. No
Affiliate of the Company shall maintain joint bank accounts with the Company or
other depository accounts with the Company to which any such Affiliate has
independent access. The Company's operating expenses shall not be paid by
Milacron or any other Affiliate of the Company, and the Company shall have its
own stationary. The Company shall conduct its business solely in its own legal
name and in a manner separate from Milacron so as not to mislead others with
whom it is dealing.

                                       75
<PAGE>

      The books of account, financial reports and records of the Company shall
be maintained separately from those of Milacron and each other Affiliate of the
Company, although they may appear in Milacron's consolidated general ledger. Any
financial statements of Milacron or an Affiliate thereof which are consolidated
to include the Company shall contain detailed notes clearly stating that (1) all
of the Company's assets are owned by the Company, and (2) the Company is a
separate legal entity with its own separate creditors that shall be entitled to
be satisfied out of the Company's assets prior to any value in the Company
becoming available to the Company's equity holders. The Company's assets shall
be maintained in a manner that facilitates their identification and segregation
from those of Milacron and its other Affiliates.

      The Company shall maintain arm's length relationships with its Affiliates,
and each Affiliate of the Company that renders or otherwise furnishes services
or merchandise to the Company shall be compensated by the Company at market
rates for such services or merchandise. The Company shall not incur any material
indirect or overhead expenses for items shared with Milacron (or any other
Affiliate thereof) or any fees for legal, auditing and other professional
services and directors' fees, in each case that are not reflected in a service
agreement between the Company and Milacron pursuant to which a fee shall be paid
to Milacron for any such expenses; it being understood that Milacron shall pay
the expenses relating to the offering of the Notes.

      No Affiliate of the Company shall be, nor shall it hold itself out to be,
responsible for the debts of the Company or the decisions or actions in respect
of the daily business and affairs of the Company. The Company shall immediately
correct any known misrepresentation with respect to the foregoing and shall not
operate or purport to operate as an integrated single economic unit with respect
to Milacron or in its dealing with any other entity.

                                   SUCCESSORS

Section 5.01 Merger, Consolidation, or Sale of Assets.

      The Company may not, directly or indirectly: (1) consolidate or merge with
or into another Person (whether or not the Company is the surviving
corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of the properties or assets of the Company and its
Restricted Subsidiaries taken as a whole, in one or more related transactions,
to another Person; unless:

            (1) either:

                  (A) the Company is the surviving corporation; or

                  (B) the Person formed by or surviving any such consolidation
            or merger (if other than the Company) or to which such sale,
            assignment, transfer, conveyance or other disposition has been made
            is a Person organized or existing under the laws of the United
            States, any state of the United States or the District of Columbia
            (any such Person, the "Successor Company");

            (2) the Successor Company assumes all the obligations of the Company
      under the Notes, this Indenture, the Security Documents and, if then in
      effect, the Registration Rights Agreement pursuant to agreements
      reasonably satisfactory to the Trustee;

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

                                       76
<PAGE>

            (4) the Company or the Successor Company, as the case may be, would
      on the date of such transaction after giving pro forma effect thereto and
      any related financing transactions as if the same had occurred at the
      beginning of the applicable four-quarter period:

                  (A) be permitted to incur at least $1.00 of additional
            Indebtedness pursuant to Section 4.09 hereof or

                  (B) have a Fixed Charge Coverage Ratio that is no worse than
            the Fixed Charge Coverage Ratio of the Company immediately preceding
            such consolidation, merger, sale, assignment, transfer, conveyance
            or other disposition.

      The foregoing clause (4) of this Section 5.01 will not prohibit:

            (1) the Escrow Merger; or

            (2) a merger between the Company and any of its Restricted
      Subsidiaries; or

            (3) a merger between the Company and an Affiliate of the Company
      incorporated solely for the purpose of reincorporating the Company in
      another state of the United States, so long as the amount of Indebtedness
      of the Company and its Restricted Subsidiaries is not increased thereby.

      In addition, the Company may not, directly or indirectly, lease all or
substantially all of its properties or assets, in one or more related
transactions, to any other Person. This Section 5.01 will not apply to a sale,
assignment, transfer, conveyance or other disposition of assets between or among
the Company, any of its Wholly Owned Restricted Subsidiaries and any of the
Guarantors.

Section 5.02   Successor Company Substituted.

      Upon any consolidation or merger with, or any sale, assignment, transfer,
lease, conveyance or other disposition of all or substantially all of the
properties or assets of the Company to a Successor Company in a transaction that
is subject to, and that complies with the provisions of, Section 5.01 hereof,
the Successor Company shall succeed to, and be substituted for (so that from and
after the date of such consolidation, merger, sale, assignment, transfer, lease,
conveyance or other disposition, the provisions of this Indenture referring to
the "Company" shall refer instead to the Successor Company), and may exercise
every right and power of the Company under this Indenture with the same effect
as if such Successor Company had been named as the Company herein; provided,
however, that the predecessor Company shall not be relieved from the obligation
to pay the principal of and interest on the Notes except in the case of a sale
of substantially all of the properties or assets of the Company and its
Restricted Subsidiaries taken as a whole in a transaction that is subject to,
and that complies with the provisions of, Section 5.01 hereof.

                              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, or
      Liquidated Damages with respect to, the Notes;

                                       77
<PAGE>

            (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 the Company to comply with its obligations under
      Sections 4.10, 4.15, 4.21 or 5.01 hereof;

            (4) failure by the Company or any of its Restricted Subsidiaries for
      30 days after receipt by the Company of written notice by the Trustee or
      the Holders of at least 25% in aggregate principal amount of the Notes
      then outstanding (including Additional Notes, if any) voting as a single
      class to comply with the provisions of Sections 4.07 and 4.09;

            (5) failure by the Company or any of its Restricted Subsidiaries for
      60 days after notice to the Company 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, the Escrow Agreement, the Notes or the Security Documents;

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

                  (A) is caused by a failure to pay principal of such
            Indebtedness (after giving effect to any applicable grace period
            provided in such Indebtedness) on the date of its Stated Maturity (a
            "Payment Default"); or

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

            and, in each case, the principal amount of any such Indebtedness,
            together with the principal amount of any other such Indebtedness
            under which there has been a Payment Default or the maturity of
            which has been so accelerated, aggregates $15.0 million or more;

            (7) failure by the Company or any of its Restricted Subsidiaries to
      pay final, non-appealable judgments entered by a court or courts of
      competent jurisdiction aggregating in excess of $15.0 million, which
      judgments are not paid, discharged or stayed for a period of 60 days;

            (8) the Escrow Agreement or any other Security Document or any Lien
      purported to be granted thereby on the Escrow Account or the cash therein,
      the Eurobond Escrow Agreement or any other security document or any Lien
      purposed to be granted thereby on the Eurobond Escrow Account, or the cash
      therein, or any one or more other items of Collateral having an aggregate
      fair market value in excess of $15.0 million is held in any judicial
      proceeding to be unenforceable or invalid, in whole or in part, or ceases
      for any reason (other than pursuant to a release that is delivered or
      becomes effective as set forth in this Indenture) to be fully enforceable
      and perfected; provided that if the holders of the Series B Notes and the
      common stock into which the Series A Notes were converted waive the
      requirement in the Note Purchase Agreement for the establishment of the
      Eurobond Escrow Account, then the failure to establish the Eurobond Escrow
      Account or execute the Eurobond Escrow Agreement (or the termination of

Section 6.02 Acceleration.

      In the case of an Event of Default specified in clause (11) or (12) of
Section 6.01 hereof, with respect to the Company, any Restricted Subsidiary of
the Company that is a Significant Subsidiary or any group of Restricted
Subsidiaries of the Company that, taken together, would constitute a Significant

                                       79
<PAGE>

Subsidiary, all outstanding Notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and
payable immediately.

      Upon any such declaration, the Notes shall become due and payable
immediately.

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

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 Liquidated
Damages, if any, 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.

      Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium and Liquidated Damages, if any, or interest
on, the Notes (including in connection with an offer to purchase); provided,
however, that the Holders of a majority in aggregate principal amount of the
then outstanding Notes may rescind an acceleration and its consequences,
including any related payment default that resulted from such acceleration. Upon
any such waiver, such Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

Section 6.05 Control by Majority.

      Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability.

Section 6.06 Limitation on Suits.

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

            (1) such Holder gives to the Trustee written notice that an Event of
      Default is continuing;

                                       80
<PAGE>

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

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

            (4) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer of security or indemnity; and

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

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

Section 6.07 Rights of Holders of Notes to Receive Payment.

      Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium and Liquidated
Damages, 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;
provided that a Holder shall not have the right to institute any such suit for
the enforcement of payment if and to the extent that the institution or
prosecution thereof or the entry of judgment therein would, under applicable
law, result in the surrender, impairment, waiver or loss of the Lien of this
Indenture upon any property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

      If an Event of Default specified in Section 6.01(1) or (2) hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of
principal of, premium and Liquidated Damages, if any, 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 of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.07 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and

                                       81
<PAGE>

other properties that the Holders may be entitled to receive in such proceeding
whether in liquidation or under any plan of reorganization or arrangement or
otherwise. Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder, or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding.

Section 6.10 Priorities.

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

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

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

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

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

Section 6.11 Undertaking for Costs.

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 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
aggregate principal amount of the then outstanding Notes.

                                     TRUSTEE

Section 7.01 Duties of Trustee.

      (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

                                       82
<PAGE>

      Indenture and no others, and no implied covenants or obligations shall be
      read into this Indenture against the Trustee; and

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

risk its own funds or incur any liability. The Trustee will be under no

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 Company. Money held in

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.

request, direction or notice from the Company will be sufficient if signed by an
Officer of the Company.

      (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 indemnity
or security against the losses, liabilities and expenses that might be incurred
by it in compliance with such request or direction.

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 Company or any Affiliate of
the Company with the same rights it would have if it were not Trustee. However,
in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the SEC for permission to
continue as trustee (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.

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 Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it 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 of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium or
Liquidated Damages, if any, or interest on, any Note, the Trustee may withhold
the notice if and so long as a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of the Holders
of the Notes.

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 Section 313(a) (but if no event described
in TIA Section 313(a) has occurred within the twelve months preceding the
reporting date, no report need be transmitted). The Trustee also will comply
with TIA Section 313(b)(2). The Trustee will also transmit by mail all reports
as required by TIA Section 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 Company and filed by the Trustee with
the SEC and each stock exchange on which the Notes are listed in accordance with

are listed on any stock exchange.

Section 7.07 Compensation and Indemnity.

                                       84
<PAGE>

      (a) The Company will pay to the Trustee from time to time reasonable
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 Company 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) The Company and the Guarantors 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
the Company and the Guarantors (including this Section 7.07) and defending
itself against any claim (whether asserted by the Company, the Guarantors, any
Holder or any other Person) or liability in connection with the exercise or
performance of any of its powers or duties hereunder, except to the extent any
such loss, liability or expense may be attributable to its negligence or bad
faith. The Trustee will notify the Company promptly of any claim for which it
may seek indemnity. Failure by the Trustee to so notify the Company will not
relieve the Company or any of the Guarantors of their obligations hereunder. The
Company or such Guarantor will defend the claim and the Trustee will cooperate
in the defense. The Trustee may have separate counsel and the Company will pay
the reasonable fees and expenses of such counsel. Neither the Company nor any
Guarantor need pay for any settlement made without its consent, which consent
will not be unreasonably withheld. Neither the Company nor any Guarantor need
reimburse any expense or indemnify against any loss, liability or expense
incurred by the Trustee through its own negligence, willful misconduct or bad
faith.

      (c) The obligations of the Company and the Guarantors under this Section
7.07 will survive the satisfaction and discharge of this Indenture.

      (d) To secure the Company's and the 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(11) or (12) 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 Section 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 Company. The Holders of a majority
in aggregate principal amount of the then outstanding Notes may remove the
Trustee by so notifying the Trustee and the Company in writing. The Company may
remove the Trustee by so notifying the Trustee. The Company shall remove the
Trustee if:

      for relief is entered with respect to the Trustee under any Bankruptcy
      Law;

      property; or

            (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 Company will promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

      (d) If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company, or
the Holders of at least 10% in aggregate 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 Company. 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 Company'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.

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.

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 Company,
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 and Liquidated
      Damages, if any, on, such Notes when such payments are due from the trust
      referred to in Section 8.04 hereof;

            (2) the Company'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 the Company's and the Guarantors' obligations in connection
      therewith; and

            (4) this Article 8.

      Subject to compliance with this Article 8, the Company may exercise its
option under this Section 8.02 notwithstanding the prior exercise of its option
under Section 8.03 hereof.

Section 8.03 Covenant Defeasance.

      Upon the Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, the Company and each of the 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 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19,
4.20, and 4.21 hereof and clause (4) of Section 5.01 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

                                       87
<PAGE>

thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but 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, the Company and the 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 Company's exercise under Section 8.01 hereof of the option
applicable to this Section 8.03, subject to the satisfaction of the conditions
set forth in Section 8.04 hereof, Sections 6.01(3) through 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 Company must irrevocably deposit with the Trustee, in trust,
      for the benefit of the Holders of the Notes, cash in U.S. dollars,
      non-callable Government Securities, or a combination of cash in U.S.
      dollars and non-callable Government Securities, in amounts as will be
      sufficient, in the opinion of a nationally recognized firm of independent
      public accountants, to pay the principal of, or interest and premium and
      Liquidated Damages, if any, on the outstanding Notes on the stated
      maturity or on the applicable redemption date, as the case may be, and the
      Company must specify whether the Notes are being defeased to maturity or
      to a particular redemption date;

            (2) in the case of Legal Defeasance only, the Company has delivered
      to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
      confirming that:

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

                  (B) since the date 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 will confirm that, the Holders of the outstanding Notes will
            not recognize income, gain or loss for federal income tax purposes
            as a result of such Legal Defeasance and will be subject to federal
            income tax on the same amounts, in the same manner and at the same
            times as would have been the case if such Legal Defeasance had not
            occurred;

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

            (4) no Default 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);

                                       88
<PAGE>

            (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 the Company
      or any of its Subsidiaries is a party or by which the Company or any of
      its Subsidiaries is bound;

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

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

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

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

      The Company 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 Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.04(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 Company.

      Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of, premium or Liquidated
Damages, if any, or interest on, any Note and remaining unclaimed for two years
after such principal, premium or Liquidated Damages, if any, or interest has
become due and payable shall be paid to the Company on its request or (if then
held by the Company) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Company for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, 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
Company cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that,
after a

                                       89
<PAGE>

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 Company.

Section 8.07 Reinstatement.

      If the Trustee or Paying Agent is unable to apply any U.S. dollars or
non-callable Government Securities in accordance with Section 8.02 or 8.03
hereof, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's and the 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 Company makes any payment of principal of, premium or
Liquidated Damages, if any, or interest on, any Note following the reinstatement
of its obligations, the Company 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, the Company, the
Guarantors and the Trustee may amend or supplement this Indenture or the Notes
or the Note Guarantees without the consent of any Holder of Note:

            (1) to cure any ambiguity, defect or inconsistency or to make a
      modification of a formal, minor or technical nature or correct a manifest
      error;

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

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

            (4) to add to the covenants of the Company or any Guarantor for the
      benefit of Holders of the Notes or surrender any right or power conferred
      upon the Company or any Guarantor;

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

            (6) to comply with any requirement of the SEC in connection with the
      qualification of this Indenture under the Trust Indenture Act;

            (7) to add any additional Guarantor or to release any Guarantor from
      its Note Guarantee, to evidence or provide for the acceptance of
      appointment of a successor trustee or to add any additional Events of
      Default, in each case, as provided in this Indenture;

            (8) to make, complete or confirm any grant of a security interest in
      any Collateral permitted or required by the Security Documents or this
      Indenture or any release of Collateral that becomes effective as set forth
      in the Security Documents or this Indenture;

                                       90
<PAGE>

            (9) to conform the text of this Indenture, the Note Guarantees, the
      Intercreditor Agreement, the other Security Documents or the Notes to any
      provision of the "Description of Senior Secured Notes" section of the
      Offering Circuler, to the extent that such provision in that "Description
      of Senior Secured Notes" was intended to be a verbatim recitation of a
      provision of this Indenture, the Note Guarantees, the Intercreditor
      Agreement, the other Security Documents or the Notes;

            (10) to comply with Sections 5.01 and 4.10 hereof;

            (11) to reflect any waiver or termination of any right arising under
      the provisions of the Intercreditor Agreement that otherwise would be
      enforceable by any holder of a Credit Facility Lien, if such waiver or
      termination is set forth or provided in this Indenture, any of the
      Security Documents or the agreement governing or giving rise to such
      Credit Facility Lien, provided that no such waiver or amendment pursuant
      to this clause (11) shall adversely affect the rights of Holders of the
      Notes; and

            (12) to release Collateral constituting Excluded Securities in
      accordance with the conditions set forth in the definition of Excluded
      Assets.

      Upon the request of the Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee will join with the Company and the Guarantors in the
execution of any amended or supplemental indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee 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, the Company and the Trustee
may amend or supplement this Indenture (including, without limitation, Section
3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the
consent of the Holders of at least a majority in aggregate principal amount of
the then outstanding Notes (including, 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), and,
subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of
Default (other than a Default or Event of Default in the payment of the
principal of, premium or Liquidated Damages, 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 or the Notes or the Note
Guarantees may be waived with the consent of the Holders of a majority in
aggregate principal amount of the then outstanding Notes (including, 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 Company accompanied by a resolution of its Board
of Directors authorizing the execution of any such amended or supplemental
indenture, and upon the filing with the Trustee of evidence satisfactory to the
Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by
the Trustee of the documents described in Section 7.02 hereof, the Trustee will
join with the Company and the 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

                                       91
<PAGE>

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 be 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 Company will mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, will not, however, in
any way impair or affect the validity of any such amended or supplemental
indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a
majority in aggregate principal amount of the Notes then outstanding voting as a
single class may waive compliance in a particular instance by the Company with
any provision of this Indenture or the Notes or the Note Guarantees. 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 change the fixed maturity of any Note
      or alter the provisions with respect to the redemption of the Notes
      (except as provided above with respect to Sections 3.09, 4.10 and 4.15
      hereof);

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

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

            (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 the rights of Holders of Notes to receive
      payments of principal of, or interest or premium or Liquidated Damages, 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); or

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

      In addition, any amendment to, or waiver of, the provisions of this
Indenture to release all or substantially all of the Collateral from the Liens
securing the Notes or to release any Guarantor from any of its obligations under
its Note Guarantee or this Indenture, except in accordance with the terms of
this Indenture, will require the consent of the Holders of at least 66-2/3% in
aggregate principal amount of the Notes then outstanding. Further, no amendment
or supplement that imposes any obligation on the Trustee or the Collateral Agent
or adversely affect the rights of the Trustee or the Collateral Agent in its
individual capacity shall become effective without the consent of such party.

                                       92
<PAGE>

Section 9.03 Compliance with Trust Indenture Act.

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

Section 9.04 Revocation and Effect of Consents.

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

Section 9.05 Notation on or Exchange of Notes.

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

      Failure to make the appropriate notation or issue a new Note 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. In
executing any amended or supplemental indenture, the Trustee will be entitled to
receive and (subject to Section 7.01 hereof) will be fully protected in relying
upon, in addition to the documents required by Section 12.04 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 AND SECURITY

Section 10.01. Collateral Documents.

      The due and punctual payment of the principal of and interest and
Liquidated Damages, if any, on the Notes when and as the same shall be due and
payable, whether on an interest payment date, at maturity, by acceleration,
repurchase, redemption or otherwise, and, to the extent permitted by law,
interest on the overdue principal of and interest and Liquidated Damages, if
any, on the Notes and the Note Guarantees and performance of all other
obligations of the Company and the Guarantors to the Holders of Notes or the
Trustee under this Indenture, the Notes and the Note Guarantees, according to
the terms hereunder or thereunder, will be secured as provided in the Senior
Secured Note Documents constituting Security Documents (the "Note Security
Documents") which the Company and the Guarantors, as applicable, will enter into
concurrently with the expiration of the Escrow Period and the consummation of
the Escrow Merger. Each Holder of Notes, by its acceptance thereof, consents and
agrees to the terms of the Note Security Documents (including, without
limitation, the provisions providing for foreclosure and release of the
Collateral) as the same may be in effect or may be amended

                                       93
<PAGE>

from time to time in accordance with its terms and authorizes and directs the
Trustee for the benefit of the Holders of Notes and the Collateral Agent to
enter into the Note Security Documents and to perform their respective
obligations and exercise their respective rights thereunder in accordance
therewith. The Company and each of the Guarantors will do or cause to be done
all acts and things that may be required, or that the Collateral Agent from time
to time may reasonably request, to assure and confirm that the Collateral Agent
holds, for the benefit of the holders of Senior Secured Note Obligations, duly
created and enforceable and perfected Liens upon the Collateral, including any
property or assets that are acquired or otherwise become Collateral after the
Notes are issued, subject to Permitted Prior Liens in the case of Senior Secured
Note Priority Collateral, and to Credit Facility Liens and other Liens, if any,
permitted by the applicable Qualified Credit Facility to be prior to the Credit
Facility Liens in the case of Credit Facility Priority Collateral, in each case,
as contemplated hereby and by the Senior Secured Note Documents.

      Upon the reasonable request of the Collateral Agent or the trustee at any
time and from time to time, the Company and each of the Guarantors will promptly
execute, acknowledge and deliver such security documents, instruments,
certificates, notices and other documents, and take such other actions as shall
be reasonably required, or that the Collateral Agent may reasonably request, to
create, perfect, protect, assure or enforce the Liens and benefits intended to
be conferred, in each case as contemplated by the Senior Secured Note Documents
for the benefit of the holders of Senior Secured Note Obligations.

Section 10.02. Recording and Opinions.

      (a) The Company will furnish to the Collateral Agent and the Trustee on
May 15 in each year beginning with May 15, 2005, an Opinion of Counsel, which
may be rendered by internal counsel to the Company, dated as of such date,
either:

            (1) to the effect that, in the opinion of such counsel, subject to
      customary qualifications, such action has been taken with respect to the
      recordings, registerings, filings, re-recordings, re-registerings and
      refilings of this Indenture, the Note Security Documents and all financing
      statements, continuation statements or other instruments of further
      assurance as is necessary to maintain the Lien of the Note Security
      Documents in the Collateral and reciting with respect to the security
      interest in such Collateral the details of such action or referencing to
      prior Opinions of Counsel in which such details are given; or

            (2) to the effect that, in the opinion of such Counsel, subject to
      customary qualifications, no such action is necessary to maintain such
      Lien.

      (b) The Company will otherwise comply with the provisions of TIA
Section 314(b).

Section 10.03. Release of Collateral.

      (a) Subject to the provisions of this Section 10.03, Collateral may be
released from the Lien and security interest created by the Note Security
Documents at any time or from time to time in accordance with the provisions of
the Note Security Documents or as provided by this Indenture. Collateral will be
released from the Lien and security interest created by the Note Security
Documents upon the occurrence of any of the following events:

            (1) in whole, upon payment in full of the Notes and all other Senior
      Secured Note Obligations that are outstanding, due and payable at the time
      the Notes are paid in full;

            (2) upon satisfaction and discharge of this Indenture as set forth
      in Article 12 hereof;

                                       94
<PAGE>

            (3) upon a Legal Defeasance or Covenant Defeasance as set forth in
      Article 8 hereof;

            (4) as to any Collateral that constitutes all or substantially all
      of the Collateral, with the consent of the Holders of 66-2/3% in principal
      amount of the Notes then outstanding (including, without limitation,
      consents obtained in connection with a tender offer or exchange offer for,
      or purchase of, the Notes);

            (5) as to any Collateral that constitutes less than all or
      substantially all of the Collateral, with the consent of the Holders of a
      majority in principal amount of the Notes then outstanding (including,
      without limitation, consents obtained in connection with a tender offer or
      exchange offer for, or purchase of, the notes);

            (6) automatically as to any Collateral that is sold, transferred or
      otherwise disposed of by the Company or any other Obligor to a Person that
      is not (either immediately before or after such sale, transfer or
      disposition) the Company or a Restricted Subsidiary of the Company in a
      transaction or other circumstance that is not prohibited by Section 4.10
      hereof and is not prohibited by all of the other Senior Secured Note
      Documents, at the time of such sale, transfer or other disposition or to
      the extent of the interest sold, transferred or otherwise disposed of;
      provided that the Collateral Agent's Liens upon the Collateral will not be
      released if the sale or disposition is prohibited by Section 5.01 hereof;

            (7) automatically as to any Collateral owned by any Guarantor all of
      the Capital Stock of which is being sold, transferred or otherwise being
      disposed of to a Person that is not (either immediately before or after
      giving effect to such transaction) the Company or a Restricted Subsidiary
      of the Company in a transaction that does not violate Section 4.10 hereof,
      at the time of such sale, transfer or other disposition;

            (8) automatically as to any Collateral owned by any Restricted
      Subsidiary that is a Guarantor, upon (a) the designation of such
      Restricted Subsidiary as an Unrestricted Subsidiary in accordance with the
      applicable provisions of this Indenture or (b) if such Restricted
      Subsidiary is not a Domestic Restricted Subsidiary, when it ceases to be a
      guarantor or otherwise provide direct credit support for any other
      Indebtedness of the Company or any Guarantor;

            (9) automatically as to any Credit Facility Priority Collateral, in
      the event of any private or public sale of all or any portion of such
      Credit Facility Priority Collateral in connection with any Exercise of
      Remedies by or with the consent of the Credit Facility Agent at any time
      prior to the date upon which the Discharge of Credit Facility Obligations
      shall have occurred (and irrespective of whether an Event of Default has
      occurred), so long as the net cash proceeds of any such sale are applied
      as set forth under the Intercreditor Agreement;

            (10) as to Excluded Securities, in accordance with the conditions
      set forth in the definition of Excluded Assets; and

            (11) as to any Credit Facility Priority Collateral, upon delivery of
      certification to the Trustee and the Collateral Agent by a Credit Facility
      Agent to the effect that such Credit Facility Priority Collateral has been
      released by the requisite number of holders of the Credit Facility
      Obligations in accordance with the terms of the Credit Facility Documents;
      provided that at the time of such release, the aggregate principal amount
      of Credit Facility Debt outstanding (including outstanding letters of
      credit, whether or not then available or drawn) and the aggregate unfunded
      commitments to extend credit that, when funded, would constitute Credit
      Facility Debt must exceed $25 million.

                                       95
<PAGE>

      Upon receipt of an Officers' Certificate certifying that all conditions
precedent to such release have been met, the Collateral Agent shall execute,
deliver or acknowledge any necessary or proper instruments of termination,
satisfaction or release to evidence the release of any Senior Secured Note
Priority Collateral or the Credit Facility Priority Collateral permitted to be
released pursuant to this Indenture or the Note Security Documents.

      (b) 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 Collateral Agent, no release of Collateral pursuant to the provisions of
the Note Security Documents will be effective as against the Holders of Notes.

      (c) The release of Collateral from the terms of this Indenture and the
Note Security Documents will not be deemed to impair the security under this
Indenture in contravention of the provisions hereof if and to the extent the
Collateral is released pursuant to the terms the Intercreditor Agreement or this
Indenture and any Note Security Document. To the extent applicable, the Company
will cause TIA Section 313(b), relating to reports, and TIA Section 314(d),
relating to the release of property or securities or relating to the
substitution therefor of any property or securities to be subjected to the Liens
of the Note Security Documents, to be complied with. Any certificate or opinion
required by TIA Section 314(d) may be made by an officer of the Company except
in cases where TIA Section 314(d) requires that such certificate or opinion be
made by an independent Person, which Person will be an independent engineer,
appraiser or other expert selected by or reasonably satisfactory to the trustee.
Notwithstanding anything to the contrary in this Article 10, the Company will
not be required to comply with all or any portion of TIA Section 314(d) if it
determines, in good faith based on advice of counsel, that under the terms of
TIA Section 314(d) and/or any interpretation or guidance as to the meaning
thereof of the SEC and its staff, including "no action" letters or exemptive
orders, all or any portion of TIA Section 314(d) is inapplicable to one or a
series of released Collateral.

Section 10.04. Certificates of the Company.

      The Company will furnish to the Trustee and the Collateral Agent, prior to
each proposed release of Collateral pursuant to the Note Security Documents, all
documents required by TIA Section 314(d) to the extent applicable (as the same
may be modified by any exemptive relief granted by the SEC).

      The Trustee may, to the extent permitted by Sections 7.01 and 7.02 hereof,
accept as conclusive evidence of compliance with the foregoing provisions the
appropriate statements contained in such documents and such Opinion of Counsel.

Section 10.05. Certificates of the Trustee.

      In the event that the Company wishes to release the Collateral in
accordance with the Note Security Documents and the Company has delivered the
certificates and documents required by the Note Security Documents and Sections
10.03 and 10.04 hereof, the Trustee will determine whether it has received all
documentation required by TIA Section 314(d) in connection with such release
and, if at that time the Trustee is not itself also the Collateral Agent, based
on such determination, will deliver a certificate to the Collateral Agent
setting forth such determination.

Section 10.06. Authorization of Actions to Be Taken by the Trustee Under the
Note Security Documents.

      Subject to the provisions of the Intercreditor Agreement and Sections 7.01
and 7.02 hereof, the Trustee may, in its sole discretion and without the consent
of the Holders of Notes, direct, on behalf of the Holders of Notes, the
Collateral Agent to, take all actions it deems necessary or appropriate in order
to:

                                       96
<PAGE>

            (1) foreclose upon or otherwise enforce any or all of the Senior
      Secured Note Liens;

            (2) enforce any of the terms of the Note Security Documents; and

            (3) collect and receive any and all amounts payable in respect of
      the Obligations of the Company hereunder.

      Subject to the provisions of the Intercreditor Agreement, the Trustee will
have power to institute and maintain such suits and proceedings as it may deem
expedient to prevent any impairment of the Senior Secured Note Priority
Collateral or the Credit Facility Priority Collateral by any acts that may be
unlawful or in violation of the Note Security Documents or this Indenture, and
such suits and proceedings as the Trustee may deem expedient to preserve or
protect its interests and the interests of the Holders of Notes in the Senior
Secured Note Priority Collateral or the Credit Facility Priority Collateral
(including power to institute and maintain suits or proceedings to restrain the
enforcement of or compliance with any legislative or other governmental
enactment, rule or order that may be unconstitutional or otherwise invalid if
the enforcement of, or compliance with, such enactment, rule or order would
impair the security interest hereunder or be prejudicial to the interests of the
Holders of Notes or of the Trustee).

Section 10.07. Authorization of Receipt of Funds by the Trustee Under the Pledge
Agreement.

      Subject to the provisions of the Intercreditor Agreement, the Trustee is
authorized to receive any funds for the benefit of the Holders of Notes
distributed under the Note Security Documents, and to make further distributions
of such funds to the Holders of Notes according to the provisions of this
Indenture.

Section 10.08. Termination of Security Interest.

      Upon the payment in full of the Notes and all Senior Secured Note
Obligations that are outstanding, due and payable at the time the Notes are paid
in full, upon Legal Defeasance or Covenant Defeasance or upon the consent of at
least 66-2/3% in principal amount of the Notes then outstanding as provided in
Section 9.02 hereof, the Trustee will, at the request of the Company, deliver a
certificate to the Collateral Agent instructing the Collateral Agent to release
the Liens pursuant to this Indenture and the Note Security Documents. Upon
receipt of such instructions from the Trustee, the Collateral Agent shall, at
the Company's expense, execute, deliver or acknowledge any necessary or proper
instruments of termination, satisfaction or release to evidence the release of
all such Liens.

                                   ARTICLE 11
                                 NOTE GUARANTEES

Section 11.01 Note Guarantee.

      (a) Subject to this Article 11, each of the Guarantors hereby, jointly and
severally, unconditionally guarantees to each Holder of a Note authenticated and
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the Notes or
the obligations of the Company hereunder or thereunder, that:

            (1) the principal of, premium and Liquidated Damages, 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

                                       97
<PAGE>

      all other obligations of the Company to the Holders or the Trustee
      hereunder or thereunder will be promptly paid in full or performed, all in
      accordance with the terms hereof and thereof; and

            (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, the Guarantors will be jointly and severally
obligated to pay the same immediately. Each Guarantor agrees that this is a
guarantee of payment and not a guarantee of collection.

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

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

      (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby. Each
Guarantor further agrees that, as between the 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 the Guarantors for
the purpose of this Note Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right
does not impair the rights of the Holders under the Note Guarantee.

Section 11.02 Limitation on Guarantor Liability.

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

                                       98
<PAGE>

Guarantor under this Article 11, result in the obligations of such Guarantor
under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 11.03 Execution and Delivery of the Note Guarantee.

      To evidence its Note Guarantee set forth in Section 11.01 hereof, each
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 such
Guarantor on each Note authenticated and delivered by the Trustee and that this
Indenture will be executed on behalf of such Guarantor by one of its Officers.

      Each 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.

      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 the Guarantors.

      In the event that the Company or any of its Domestic Restricted
Subsidiaries creates or acquires any Domestic Restricted Subsidiary after the
date of this Indenture, if required by Section 4.18 hereof, the Company will
cause such Domestic Restricted Subsidiary to comply with the provisions of
Section 4.18 hereof and this Article 11, to the extent applicable.

Section 11.04 Guarantors May Consolidate, etc., on Certain Terms.

      Except as otherwise provided in Section 11.05 hereof, no Guarantor may
sell or otherwise dispose of all or substantially all of its assets to, or
consolidate with or merge or amalgamate with or into (whether or not such
Guarantor is the surviving Person) another Person, other than the Company or
another Guarantor, unless:

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

            (2) subject to Section 11.05 hereof, if the Person acquiring the
      property in any such sale or disposition or the Person formed by or
      surviving any such consolidation, merger or amalgamation is a Restricted
      Subsidiary that is not already a Guarantor, such Person assumes all the
      obligations of that Guarantor under this Indenture, its Note Guarantee,
      all Note Security Documents delivered by that Guarantor and the
      Registration Rights Agreement, pursuant to a supplemental indenture and
      other documentation in form and substance reasonably satisfactory to the
      Trustee and the Capital Stock of the successor resultant Person or
      transferee Person is pledged to the Collateral Agent for the benefit of
      the Holders of the Senior Secured Note Obligations pursuant to the Note
      Security Documents; or

      In case of any such consolidation, merger, amalgamation, sale or
conveyance and upon the assumption by the successor Person, by supplemental
indenture, executed and delivered to the Trustee and satisfactory in form to the
Trustee, of the Note Guarantee endorsed upon the Notes and the due and punctual
performance of all of the covenants and conditions of this Indenture to be
performed by the Guarantor, such successor Person will succeed to and be
substituted for the Guarantor with the same

                                       99
<PAGE>

effect as if it had been named herein as a Guarantor. Such successor Person
thereupon may cause to be signed any or all of the Note Guarantees to be
endorsed upon all of the Notes issuable hereunder which theretofore shall not
have been signed by the Company 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 (1) and (2) above, nothing contained in this Indenture or in any of the
Notes will prevent any consolidation or merger of a Guarantor with or into the
Company or another Guarantor, or will prevent any sale or conveyance of the
property of a Guarantor as an entirety or substantially as an entirety to the
Company or another Guarantor.

Section 11.05  Releases.

      The Note Guarantee of a Guarantor will be released and the Guarantor
relieved of any obligation under its Note Guarantee:

            (1) in connection with any sale or other disposition of all or
      substantially all of the assets of that Guarantor (including by way of
      merger or consolidation) to a Person that is not (either immediately
      before or after giving effect to such transaction) the Company or a
      Restricted Subsidiary of the Company, if the sale or other disposition is
      not in violation of Section 4.10 hereof;

            (2) in connection with any direct or indirect sale of all of the
      Capital Stock of a Guarantor to a Person that is not (either immediately
      before or after giving effect to such transaction) the Company or a
      Restricted Subsidiary of the Company, if the sale is not in violation of
      Section 4.10 hereof;

            (3) with the written consent of the holders of at least 66-2/3% of
      the aggregate principal amount of Notes then outstanding;

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

            (5) if the Company designates any Restricted Subsidiary that is a
      Guarantor as an Unrestricted Subsidiary in accordance with Section 4.19
      hereof; or

            (6) if the Guarantor is not a Domestic Restricted Subsidiary, when
      it ceases to be a guarantor or otherwise provide direct credit support for
      any other Indebtedness of the Company or any Guarantor.

      Under any of the circumstances described in clauses (1) through (6) above,
the applicable Guarantor or Guarantors will be released from all obligations
under the Security Documents, the security interests in such Guarantor's or
Guarantors' assets created pursuant to the Security Documents will be released
and, upon any of the circumstances described in clauses (1), (2) or (4) above,
the Capital Stock of such Guarantor or Guarantors will be released from the
security interests created pursuant to the Security Documents, and in each case
all Holders of the Notes will be deemed to have consented to the foregoing
releases. At the request of the Company, the Trustee will execute and deliver
any documents, instructions or instruments giving effect to, and evidencing the
consent of the Holders to, any such release.

                                      100
<PAGE>

      Any Guarantor not released from its obligations under its Note Guarantee
as provided in this Section 11.05 will remain liable for the full amount of
principal of and interest and premium and Liquidated Damages, if any, on the
Notes and for the other obligations of any Guarantor under this Indenture as
provided in this Article 11.

                                   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, except lost,
      stolen or destroyed Notes that have been replaced or paid and Notes for
      whose payment money has been deposited in trust and thereafter repaid to
      the Company, 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 the Company or any Guarantor has irrevocably deposited or
      caused to be deposited with the Trustee as trust funds in trust solely for
      the benefit of the Holders, cash in U.S. 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 on the Notes not delivered to the Trustee for
      cancellation for principal, premium and Liquidated Damages, if any, and
      accrued interest to the date of maturity or redemption;

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

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

            (4) the Company 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 Company 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 the satisfaction and discharge of this Indenture, all Collateral will
be released from the Lien and security interest created by the Note Security
Documents pursuant to Section 10.03 and all Guarantors will be released from
their Note Guarantees pursuant to Section 11.05.

      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 hereof will
survive. In addition, nothing in this Section 12.01 will be deemed to discharge

                                      101
<PAGE>

those provisions of Section 7.07 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture.

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 Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium and Liquidated Damages, 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, the
Company's and any 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 Company has made any payment of
principal of, premium or Liquidated Damages, if any, or interest on, any Notes
because of the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the
money or Government Securities held by the Trustee or Paying Agent.

liability for any obligations of the Company or the Guarantors under the Notes,
this Indenture, the Note Guarantees, the Intercreditor Agreement, the Security
Documents or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives

            (1) INTEREST. Milacron Escrow Corporation, a Delaware corporation
      (such corporation, and its successors and assigns under the Indenture
      referred to below, being called the "Company"), promises to pay interest
      on the principal amount of this Note at 11-1/2% per annum from
      ________________, 20__ until maturity and shall pay the Liquidated
      Damages, if any, payable pursuant to Section 6 of the Registration Rights
      Agreement referred to below. The Company will pay interest and Liquidated
      Damages, if any, semi-annually in arrears on November 15 and May 15 of
      each year, or if any such day is not a Business Day, on the next
      succeeding Business Day (each, an "Interest Payment Date"). Interest on
      the Notes will accrue from the most recent date to which interest has been
      paid or, if no interest has been paid, from the date of issuance; provided
      that if there is no existing Default in the payment of interest, and if
      this Note is authenticated between a record date referred to on the face
      hereof and the next succeeding Interest Payment Date, interest shall
      accrue from such next succeeding Interest Payment Date; provided further
      that the first Interest Payment Date shall be _____________, 20__. The
      Company will pay interest (including post-petition interest in any
      proceeding under any Bankruptcy Law) on overdue principal and premium, if
      any, from time to time on demand at a rate that is 1% per annum in excess
      of the rate then in effect to the extent lawful; it will pay interest
      (including post-petition interest in any proceeding under any Bankruptcy
      Law) on overdue installments of interest and Liquidated Damages, if any,
      (without regard to any applicable grace periods) from time to time on
      demand at the same rate to the extent lawful. Interest will be computed on
      the basis of a 360-day year of twelve 30-day months.

            (2) METHOD OF PAYMENT. The Company will pay interest on the Notes
      (except defaulted interest) and Liquidated Damages, if any, to the Persons
      who are registered Holders of Notes at the close of business on the May 1
      or November 1 next preceding the Interest Payment Date, even if such Notes
      are canceled after such record date and on or before such Interest Payment
      Date, except as provided in Section 2.12 of the Indenture with respect to
      defaulted interest. The Notes will be payable as to principal, premium and
      Liquidated Damages, if any, and interest at the office or agency of the
      Company maintained for such purpose within or without the City of St.
      Paul, Minnesota, or, at the option of the Company, payment of interest and
      Liquidated Damages, if any, may be made by check mailed to the Holders at
      their addresses set forth in the register of Holders; provided that
      payment by wire transfer of immediately available funds will be required
      with respect to principal of and interest, premium and Liquidated Damages,
      if any, on, all Global Notes and all other Notes the Holders of which will
      have provided wire transfer instructions to the Company or the Paying
      Agent. Such payment will be in such coin or currency of the United States
      of America as at the time of payment is legal tender for payment of public
      and private debts.

            (3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
      Association, the Trustee under the Indenture, will act as Paying Agent and
      Registrar. The Company may change any Paying Agent or Registrar without
      notice to any Holder. The Company or any of its Subsidiaries may act in
      any such capacity.

            (4) INDENTURE AND SECURITY DOCUMENTS. The Company issued the Notes
      under an Indenture dated as of May 26, 2004 (the "Indenture") between the
      Company and the Trustee. The terms of the Notes include those stated in
      the Indenture and those made part of the Indenture by reference to the
      TIA. The Notes are subject to all such terms, and Holders are referred to
      the Indenture and such Act for a statement of such terms. To the extent
      any provision of this Note conflicts with the express provisions of the
      Indenture, the provisions of the Indenture shall govern and be
      controlling. The Notes are secured obligations of the Company. The Notes
      are secured by a pledge of Collateral pursuant to the Security Documents
      referred to in the Indenture. The Company shall be entitled, subject to
      compliance with Section 4.09 of the Indenture, to issue Additional Notes

principal amount thereof, plus accrued and unpaid interest and Liquidated
Damages, if any, to the redemption date, with the net cash proceeds of one or
more Qualified Equity Issuances; provided that:

            (1) at least 65% of the aggregate principal amount of Notes
      initially issued under the Indenture remains outstanding immediately after
      the occurrence of such redemption (excluding Notes held by the Company and
      its Subsidiaries); and

            (2) the redemption occurs within 90 days of the date of the closing
      of such Qualified Equity Issuance.

      (b) The Company may also at its option on any one or more occasions redeem
all or part of the Notes upon not less than 30 nor more than 60 days prior
notice, at a redemption price equal to 100% of the principal amount thereof plus
the Applicable Premium as of the date of redemption.

            (6) MANDATORY REDEMPTION.

      Other than in connection with redemption pursuant to a Special Mandatory
Redemption, the Company is not required to make mandatory redemption or sinking
fund payments with respect to the Notes.

            (7) SPECIAL MANDATORY REDEMPTION.

      In accordance with the terms and conditions of the Escrow Agreement, and
using the funds in the Escrow Account, the Company shall redeem on the Escrow
Redemption Date all and not less than all of the Notes at the Escrow Redemption
Price if the Officers' Certificate required by Section 3(b) of the Escrow
Agreement to be delivered by July 29, 2004 (the "Conditions Precedent Date") (or
if the Conditions Precedent Date has been extended pursuant to the terms of the
Escrow Agreement, by August 31, 2004) has not been so delivered. Upon the
release of the funds from the Escrow Account after delivery of the Officers'
Certificate required by Section 3(b) of the Escrow Agreement, the foregoing
provisions of this Section 7 shall be null and void.

            (8) REPURCHASE AT THE OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company will be
      required to 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
      thereof) of each Holder's Notes validly tendered in the Change of Control
      Offer at a purchase price in cash equal to 101% of the aggregate principal
      amount thereof plus accrued and unpaid interest and Liquidated Damages, if
      any, thereon to the date of purchase, subject to the rights of 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 Company will mail a notice to each Holder
      setting forth the procedures governing the Change of Control Offer as
      required by the Indenture.

                  (b) If the Company or a Restricted Subsidiary of the Company
      consummates any Asset Sales, within five Business Days of each date on
      which the aggregate amount of Excess Proceeds exceeds $10.0 million, the
      Company will commence an offer to all Holders of Notes (an "Asset Sale
      Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum
      principal amount of Notes (including any Additional Notes) that may be
      purchased out of the Excess Proceeds at an offer price in cash in an
      amount equal to 100% of the principal amount thereof plus accrued and
      unpaid interest and Liquidated Damages, if any, thereon to the date of
      purchase, in accordance with the procedures set forth in the Indenture. To
      the extent that the aggregate amount of Notes (including any Additional
      Notes) tendered pursuant to an Asset Sale Offer is less than the Excess
      Proceeds, the Company (or such Restricted Subsidiary) may use such
      deficiency for any purpose not otherwise prohibited by the Indenture. If
      the aggregate principal amount of Notes tendered into such Asset Sale
      Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
      Notes to be purchased on a pro rata basis. Holders of Notes that are the
      subject of an offer to purchase will receive an Asset Sale Offer from the
      Company prior to any related purchase date and may elect to have such
      Notes purchased by completing the form entitled "Option of Holder to Elect
      Purchase" attached to the Notes.

                  (c) If the Company or a Restricted Subsidiary of the Company
      consummates any Sale of Senior Secured Note Priority Collateral, within
      five Business Days of each date on which the aggregate amount of Excess
      Collateral Proceeds exceeds $10.0 million, the Company will commence an
      offer to all Holders of Notes (a "Collateral Proceeds Offer") pursuant to
      Section 3.10 of the Indenture to purchase the maximum principal amount of
      Notes (including any Additional Notes) that may be purchased out of the
      Excess Collateral Proceeds at an offer price in cash in an amount equal to
      100% of the principal amount thereof plus accrued and unpaid interest and
      Liquidated Damages, if any, thereon to the date of purchase, in accordance
      with the procedures set forth in the Indenture. To the extent that the
      aggregate amount of Notes (including any Additional Notes) tendered
      pursuant to an Collateral Proceeds Offer is less than the Excess
      Collateral Proceeds, the Company (or such Restricted Subsidiary) may use
      such deficiency for any purpose not otherwise prohibited by the Indenture.
      If the aggregate principal amount of Notes tendered into such Collateral
      Proceeds Offer exceeds the amount of Excess Collateral Proceeds, the
      Trustee shall select the Notes to be purchased on a pro rata basis.
      Holders of Notes that are the subject of an offer to purchase will receive
      an Collateral Proceeds Offer from the Company prior to any related
      purchase date and may elect to have such Notes purchased by completing the
      form entitled "Option of Holder to Elect Purchase" attached to the Notes.

            (9) NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address, 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 or discharge of the Indenture. Notes in denominations larger
      than $1,000 may be redeemed in part but only in whole multiples of $1,000,
      unless all of the Notes held by a Holder are to be redeemed. On and after
      the applicable redemption date, interest ceases to accrue on the Notes or
      portion thereof called for redemption.

            (10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples of
      $1,000. The transfer of Notes may be registered and Notes may be exchanged
      as provided in the Indenture. The Registrar and the Trustee may require a
      Holder, among other things, to furnish appropriate endorsements and
      transfer documents and the Company may require a Holder to pay any taxes
      and fees required by law or permitted by the Indenture. The Company need
      not exchange or register the transfer of any Note or portion of a Note
      selected for redemption, except for the unredeemed portion of any Note
      being redeemed in part. Also, the Company need not exchange or register
      the transfer of any Notes for a period of 15 days before a selection of
      Notes to be redeemed or during the period between a record date and the
      corresponding Interest Payment Date.

            (11) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
      exceptions, the Indenture or the Notes or the Note Guarantees may be
      amended or supplemented with the consent of the Holders of at least a
      majority in aggregate principal amount of the then outstanding Notes
      including Additional Notes, if any, voting as a single class, and any
      existing Default or Event or Default or compliance with any provision of
      the Indenture or the Notes or the Note Guarantees may be waived with the
      consent of the Holders of a majority in aggregate principal amount of the
      then outstanding Notes including Additional Notes, if any, voting as a
      single class. Without the consent of any Holder of a Note, the Indenture
      or the Notes or the Note Guarantees may be amended or supplemented (1) to
      cure any ambiguity, defect or inconsistency or to make a modification of a
      formal, minor or technical nature or correct a manifest error; (2) to
      provide for uncertificated Notes in addition to or in place of
      Certificated Notes; (3) to provide for the assumption of the Company's or
      a Guarantor's obligations to Holders of the Notes in the case of a merger
      or consolidation or a sale of all or substantially all of the Company's
      assets; (4) to add to the covenants of the Company or any Guarantor for
      the benefit of the Holders of the Notes or surrender any right or power
      conferred upon the Company or any Guarantor; (5) to make any change that
      would provide any additional rights or benefits to the Holders of the
      Notes or that does not adversely affect the legal rights under the
      Indenture of any such Holder; (6) to comply with any requirement of the
      SEC in connection with the qualification of the Indenture under the TIA;
      (7) to add any additional Guarantor or to release any Guarantor from its
      Note Guarantee, to evidence or provide for the acceptance of appointment
      of a successor trustee or to add any additional Events of Default, in each
      case, as provided in the Indenture; (8) to make, complete or confirm any
      grant of a security interest in any Collateral permitted or required by
      the Security Documents or the Indenture or any release of Collateral that
      becomes effective as set forth in the Security Documents or the Indenture;
      (9) to conform the text of the Indenture, the Note Guarantees, the
      Intercreditor Agreement, the other Security Documents or the Notes to any
      provision of the "Description of Senior Secured Notes" section of the
      Offering Circular dated May 12, 2004, to the extent that such provision in
      that "Description of Senior Secured Notes" was intended to be a verbatim
      recitation of a provision of the Indenture, the Note Guarantees, the
      Intercreditor Agreement, the other Security Documents or the Notes; (10)
      to comply with Sections 5.01 and 4.10 of the Indenture; (11) to reflect
      any waiver or termination of any right arising under the provisions of the
      Intercreditor Agreement that otherwise would be enforceable by any holder
      of a Credit Facility Lien, if such waiver or termination is set forth or
      provided in

                                      A1-5
<PAGE>

      the Indenture, any of the Security Documents or the agreement governing or
      giving rise to such Credit Facility Lien, provided that no such waiver or
      amendment pursuant to this clause (11) shall adversely affect the rights
      of Holders of the Notes; and (12) to release Collateral constituting
      Excluded Securities in accordance with the conditions set forth in the
      definition of Excluded Assets in the Indenture.

            (13) DEFAULTS AND REMEDIES. Events of Default include: (i) default
      for 30 days in the payment when due of interest on, or Liquidated Damages,
      if any, with respect to the Notes; (ii) default in the payment when due
      (at maturity, upon redemption or otherwise) of the principal of, or
      premium, if any, on, the Notes, (iii) failure by the Company to comply
      with its obligations under Sections 4.10, 4.15, 4.21 or 5.01 of the
      Indenture; (iv) failure by the Company or any of its Restricted
      Subsidiaries for 30 days after written notice by the Trustee or the
      Holders of at least 25% in aggregate principal amount of the Notes then
      outstanding (including Additional Notes, if any) voting as a single class
      to comply with the provisions of Sections 4.07 and 4.09 of the Indenture,
      (v) failure by the Company or any of its Restricted Subsidiaries for 60
      days after notice to the Company by the Trustee or the Holders of at least
      25% in aggregate principal amount of the Notes then outstanding (including
      Additional Notes, if any) voting as a single class to comply with any of
      the other agreements in the Indenture, the Escrow Agreement, the Notes, or
      the Security Documents; (vi) default under certain other agreements
      relating to Indebtedness of the Company or any of its Restricted
      Subsidiaries which default is either (a) a Payment Default or (b) results
      in the acceleration of such Indebtedness prior to its express maturity,
      and, in each case, the principal amount of such Indebtedness aggregates at
      least $15.0 million; (vii) certain final judgments for the payment of
      money that remain undischarged for a period of 60 days and aggregate in
      excess of $15.0 million; (viii) the Escrow Agreement or any other Security
      Document or any Lien purported to be granted thereby on the Escrow Account
      or the cash therein, the Eurobond Escrow Agreement or any other security
      document or any Lien purposed to be granted thereby on the Eurobond Escrow
      Account or the cash therein, or any one or more other items of Collateral
      having an aggregate fair market value in excess of $15.0 million is held
      in any judicial proceeding to be unenforceable or invalid, in whole or in
      part, or ceases for any reason (other than pursuant to a release that is
      delivered or becomes effective as set forth in the indenture) to be fully
      enforceable and perfected; provided that if the holders of the Series B
      Notes and the common stock into which the Series A Notes were converted
      waive the requirement in the Note Purchase Agreement for the establishment
      of the Eurobond Escrow Account, then the failure to establish the Eurobond
      Escrow Account or execute the Eurobond Escrow Agreement (or the
      termination of the Eurobond Escrow Agreement and dissolution of the
      Eurobond Escrow Account) shall not be deemed an Event of Default; (ix) the
      Company or any Guarantor denies or disaffirms, in writing in any pleading
      in any court of competent jurisdiction, any obligation of the Company or
      any Guarantor set forth in or arising under any Security Document; and (x)
      except as permitted by the Indenture, any Note Guarantee is held in any
      judicial proceeding to be unenforceable or invalid or shall cease for any
      reason to be in full force and effect and such default continues for 10
      days after notice by the Trustee or the Holders of at least 25% in
      aggregate principal amount of the Notes then outstanding (including
      Additional Notes, if any) voting as a single class or any Guarantor or any
      Person acting on its behalf denies or disaffirms its obligations under
      such Guarantor's Note Guarantee and (xi) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Restricted
      Subsidiaries that is a Significant Subsidiary or any group of Restricted
      Subsidiaries that, taken together, would constitute a Significant
      Subsidiary. If any Event of Default occurs and is continuing, the Trustee
      or the Holders of at least 25% in aggregate principal amount of the then
      outstanding Notes may declare all the Notes to be due and payable
      immediately. Notwithstanding the foregoing, in the case of an Event of
      Default arising from certain events of bankruptcy or insolvency, all
      outstanding Notes will become due and payable immediately without further
      action or notice. Holders may

                                      A1-6
<PAGE>

      not enforce the Indenture or the Notes except as provided in the
      Indenture. Subject to certain limitations, Holders of a majority in
      aggregate principal amount of the then outstanding Notes may direct the
      Trustee in its exercise of any trust or power. The Trustee may withhold
      from Holders of the Notes notice of any continuing Default or Event of
      Default (except a Default or Event of Default relating to the payment of
      principal or interest or premium or Liquidated Damages, if any,) if it
      determines that withholding notice is in their interest. The Holders of a
      majority in aggregate principal amount of the then outstanding Notes by
      notice to the Trustee may, on behalf of the Holders of all of the Notes,
      rescind an acceleration or waive any existing Default or Event of Default
      and its consequences under the Indenture except a continuing Default or
      Event of Default in the payment of interest or premium or Liquidated
      Damages, if any, on, or the principal of, the Notes (other than
      non-payment of amounts that became due solely because of acceleration of
      the Notes). The Company is required to deliver to the Trustee annually a
      statement regarding compliance with the Indenture, and the Company is
      required, upon becoming aware of any Default or Event of Default, to
      deliver to the Trustee a statement specifying such Default or Event of
      Default.

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

            (15) NO RECOURSE AGAINST OTHERS. No director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      have any liability for any obligations of the Company or the Guarantors
      under the Notes, the indenture, the Note Guarantees, the Intercreditor
      Agreement, the Security Documents or for any claim based on, in respect
      of, or by reason of, such obligations or their creation. Each Holder of
      Notes by accepting a Note waives and releases all such liability. The
      waiver and release are part of the consideration for issuance of the
      Notes. The waiver may not be effective to waive liabilities under the
      federal securities laws and its is the view of the Commission that such a
      waiver is against public policy.

            (16) AUTHENTICATION. This Note will not be valid until authenticated
      by the manual signature of the Trustee or an authenticating agent.

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

            (18) ADDITIONAL RIGHTS OF HOLDERS OF RESTRICTED GLOBAL NOTES AND
      RESTRICTED DEFINITIVE NOTES. In addition to the rights provided to Holders
      of Notes under the Indenture, Holders of Restricted Global Notes and
      Restricted Definitive Notes will have all the rights set forth in the
      Registration Rights Agreement dated as of May 26, 2004, between the
      Company and the other parties named on the signature pages thereof or, in
      the case of Additional Notes, Holders of Restricted Global Notes and
      Restricted Definitive Notes will have the rights set forth in one or more
      registration rights agreements, if any, among the Company, the Guarantors
      and the other parties thereto, relating to rights given by the Company and
      the Guarantors to the purchasers of any Additional Notes (collectively,
      the "Registration Rights Agreement").

            (19) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
      Committee on Uniform Security Identification Procedures, the Company has
      caused CUSIP numbers to be printed on the Notes, and the Trustee may use
      CUSIP numbers in notices of redemption as a

                                      A1-7
<PAGE>

      convenience to Holders. No representation is made as to the accuracy of
      such numbers either as printed on the Notes or as contained in any notice
      of redemption, and reliance may be placed only on the other identification
      numbers placed thereon.

            (20) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL
      GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE
      GUARANTEES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF
      LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION
      WOULD BE REQUIRED THEREBY.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

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

            (1) INTEREST. Milacron Escrow Corporation, a Delaware corporation
      (such corporation, and its successors and assigns under the Indenture
      referred to below, being called the "Company"), promises to pay interest
      on the principal amount of this Note at 11-1/2% per annum from
      ________________, 20__ until maturity and shall pay the Liquidated
      Damages, if any, payable pursuant to Section 6 of the Registration Rights
      Agreement referred to below. The Company will pay interest and Liquidated
      Damages, if any, semi-annually in arrears on November 15 and May 15 of
      each year, or if any such day is not a Business Day, on the next
      succeeding Business Day (each, an "Interest Payment Date"). Interest on
      the Notes will accrue from the most recent date to which interest has been
      paid or, if no interest has been paid, from the date of issuance; provided
      that if there is no existing Default in the payment of interest, and if
      this Note is authenticated between a record date referred to on the face
      hereof and the next succeeding Interest Payment Date, interest shall
      accrue from such next succeeding Interest Payment Date; provided further
      that the first Interest Payment Date shall be _____________, 20__. The
      Company will pay interest (including post-petition interest in any
      proceeding under any Bankruptcy Law) on overdue principal and premium, if

      of the rate then in effect to the extent lawful; it will pay interest
      (including post-petition interest in any proceeding under any Bankruptcy
      Law) on overdue installments of interest and Liquidated Damages, if any,
      (without regard to any applicable grace periods) from time to time on
      demand at the same rate to the extent lawful. Interest will be computed on
      the basis of a 360-day year of twelve 30-day months.

      Until this Regulation S Temporary Global Note is exchanged for one or more
Regulation S Permanent Global Notes, the Holder hereof shall not be entitled to
receive payments of interest hereon; until so exchanged in full, this Regulation
S Temporary Global Note shall in all other respects be entitled to the same
benefits as other Notes under the Indenture.

      (except defaulted interest) and Liquidated Damages, if any, to the Persons
      who are registered Holders of Notes at the close of business on the May 1
      or November 1 next preceding the Interest Payment Date, even if such Notes
      are canceled after such record date and on or before such Interest Payment
      Date, except as provided in Section 2.12 of the Indenture with respect to
      defaulted interest. The Notes will be payable as to principal, premium and
      Liquidated Damages, if any, and interest at the office or agency of the
      Company maintained for such purpose within or without the

                                      A2-3
<PAGE>

      interest and Liquidated Damages, if any, may be made by check mailed to
      the Holders at their addresses set forth in the register of Holders;
      provided that payment by wire transfer of immediately available funds will
      be required with respect to principal of and interest, premium and
      Liquidated Damages, if any, on, all Global Notes and all other Notes the
      Holders of which will have provided wire transfer instructions to the
      Company or the Paying Agent. Such payment will be in such coin or currency
      of the United States of America as at the time of payment is legal tender
      for payment of public and private debts.

            (3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank National
      Association, the Trustee under the Indenture, will act as Paying Agent and
      Registrar. The Company may change any Paying Agent or Registrar without
      notice to any Holder. The Company or any of its Subsidiaries may act in
      any such capacity.

            (4) INDENTURE AND SECURITY DOCUMENTS. The Company issued the Notes
      under an Indenture dated as of May 26, 2004 (the "Indenture") between the
      Company and the Trustee. The terms of the Notes include those stated in
      the Indenture and those made part of the Indenture by reference to the
      TIA. The Notes are subject to all such terms, and Holders are referred to
      the Indenture and such Act for a statement of such terms. To the extent
      any provision of this Note conflicts with the express provisions of the
      Indenture, the provisions of the Indenture shall govern and be
      controlling. The Notes are secured obligations of the Company. The Notes
      are secured by a pledge of Collateral pursuant to the Security Documents
      referred to in the Indenture. The Company shall be entitled, subject to

<PAGE>

      In accordance with the terms and conditions of the Escrow Agreement, and
using the funds in the Escrow Account, the Company shall redeem on the Escrow
Redemption Date all and not less than all of the Notes at the Escrow Redemption
Price if the Officers' Certificate required by Section 3(b) of the Escrow
Agreement to be delivered by July 29, 2004 (the "Conditions Precedent Date") (or
if the Conditions Precedent Date has been extended pursuant to the terms of the
Escrow Agreement, by August 31, 2004) has not been so delivered. Upon the
release of the funds from the Escrow Account after delivery of the Officers'
Certificate required by Section 3(b) of the Escrow Agreement, the foregoing
provisions of this Section 7 shall be null and void.

            (8) REPURCHASE AT THE OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company will be
      required to 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
      thereof) of each Holder's Notes validly tendered in the Change of Control
      Offer at a purchase price in cash equal to 101% of the aggregate principal
      amount thereof plus accrued and unpaid interest and Liquidated Damages, if
      any, thereon to the date of purchase, subject to the rights of 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 Company will mail a notice to each Holder
      setting forth the procedures governing the Change of Control Offer as
      required by the Indenture.

                  (b) If the Company or a Restricted Subsidiary of the Company
      consummates any Asset Sales, within five Business Days of each date on
      which the aggregate amount of Excess Proceeds exceeds $10.0 million, the
      Company will commence an offer to all Holders of Notes (an "Asset Sale
      Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum
      principal amount of Notes (including any Additional Notes) that may be
      purchased out of the Excess Proceeds at an offer price in cash in an
      amount equal to 100% of the principal amount thereof plus accrued and
      unpaid interest and Liquidated Damages, if any, thereon to the date of
      purchase, in accordance with the procedures set forth in the Indenture. To
      the extent that the aggregate amount of Notes (including any Additional
      Notes) tendered pursuant to an Asset Sale Offer is less than the Excess
      Proceeds, the Company (or such Restricted Subsidiary) may use such
      deficiency for any purpose not otherwise prohibited by the Indenture. If
      the aggregate principal amount of Notes tendered into such Asset Sale
      Offer exceeds the amount of Excess Proceeds, the Trustee shall select the
      Notes to be purchased on a pro rata basis. Holders of Notes that are the
      subject of an offer to purchase will receive an Asset Sale Offer from the
      Company prior to any related purchase date and may elect to have such
      Notes purchased by completing the form entitled "Option of Holder to Elect
      Purchase" attached to the Notes.

                  (c) If the Company or a Restricted Subsidiary of the Company
      consummates any Sale of Senior Secured Note Priority Collateral, within
      five Business Days of each date on which the aggregate amount of Excess
      Collateral Proceeds exceeds $10.0 million, the Company will commence an
      offer to all Holders of Notes (a "Collateral Proceeds Offer") pursuant to
      Section 3.10 of the Indenture to purchase the maximum principal amount of
      Notes (including any Additional Notes) that may be purchased out of the
      Excess Collateral Proceeds at an offer price in cash in an amount equal to
      100% of the principal amount thereof plus accrued and unpaid interest and
      Liquidated Damages, if any, thereon to the date of purchase, in accordance
      with the procedures set forth in the Indenture. To the extent that the
      aggregate amount of Notes (including any Additional Notes) tendered
      pursuant to an Collateral Proceeds Offer is less than the Excess
      Collateral Proceeds, the Company (or such Restricted Subsidiary) may use
      such deficiency for any purpose not otherwise prohibited by the Indenture.
      If the aggregate principal amount of Notes tendered into such Collateral
      Proceeds Offer exceeds the amount of Excess Collateral

                                      A2-5
<PAGE>

      Proceeds, the Trustee shall select the Notes to be purchased on a pro rata
      basis. Holders of Notes that are the subject of an offer to purchase will
      receive an Collateral Proceeds Offer from the Company prior to any related
      purchase date and may elect to have such Notes purchased by completing the
      form entitled "Option of Holder to Elect Purchase" attached to the Notes.

            (9) NOTICE OF REDEMPTION. Notice of redemption will be mailed at
      least 30 days but not more than 60 days before the redemption date to each
      Holder whose Notes are to be redeemed at its registered address, 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 or discharge of the Indenture. Notes in
      denominations larger than $1,000 may be redeemed in part but only in whole
      multiples of $1,000, unless all of the Notes held by a Holder are to be
      redeemed. On and after the applicable redemption date, interest ceases to
      accrue on the Notes or portion thereof called for redemption.

            (10) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered
      form without coupons in denominations of $1,000 and integral multiples of
      $1,000. The transfer of Notes may be registered and Notes may be exchanged
      as provided in the Indenture. The Registrar and the Trustee may require a
      Holder, among other things, to furnish appropriate endorsements and
      transfer documents and the Company may require a Holder to pay any taxes
      and fees required by law or permitted by the Indenture. The Company need
      not exchange or register the transfer of any Note or portion of a Note
      selected for redemption, except for the unredeemed portion of any Note
      being redeemed in part. Also, the Company need not exchange or register
      the transfer of any Notes for a period of 15 days before a selection of
      Notes to be redeemed or during the period between a record date and the
      corresponding Interest Payment Date.

      This Regulation S Temporary Global Note is exchangeable in whole or in
part for one or more Global Notes only (i) on or after the termination of the
40-day distribution compliance period (as defined in Regulation S) and (ii) upon
presentation of certificates (accompanied by an Opinion of Counsel, if
applicable) required by Article 2 of the Indenture. Upon exchange of this
Regulation S Temporary Global Note for one or more Global Notes, the Trustee
shall cancel this Regulation S Temporary Global Note.

            (11) PERSONS DEEMED OWNERS. The registered Holder of a Note may be
      treated as its owner for all purposes.

            (12) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
      exceptions, the Indenture or the Notes or the Note Guarantees may be
      amended or supplemented with the consent of the Holders of at least a
      majority in aggregate principal amount of the then outstanding Notes
      including Additional Notes, if any, voting as a single class, and any
      existing Default or Event or Default or compliance with any provision of
      the Indenture or the Notes or the Note Guarantees may be waived with the
      consent of the Holders of a majority in aggregate principal amount of the
      then outstanding Notes including Additional Notes, if any, voting as a
      single class. Without the consent of any Holder of a Note, the Indenture
      or the Notes or the Note Guarantees may be amended or supplemented (1) to
      cure any ambiguity, defect or inconsistency or to make a modification of a
      formal, minor or technical nature or correct a manifest error; (2) to
      provide for uncertificated Notes in addition to or in place of
      Certificated Notes; (3) to provide for the assumption of the Company's or

      the benefit of the Holders of the Notes or surrender any right or power
      conferred upon the Company or any Guarantor; (5) to make any change that
      would provide any additional rights or benefits to the Holders of the
      Notes or that

                                      A2-6
<PAGE>

      does not adversely affect the legal rights under the Indenture of any such
      Holder; (6) to comply with any requirement of the SEC in connection with
      the qualification of the Indenture under the TIA; (7) to add any
      additional Guarantor or to release any Guarantor from its Note Guarantee,
      to evidence or provide for the acceptance of appointment of a successor
      trustee or to add any additional Events of Default, in each case, as
      provided in the Indenture; (8) to make, complete or confirm any grant of a
      security interest in any Collateral permitted or required by the Security
      Documents or the Indenture or any release of Collateral that becomes
      effective as set forth in the Security Documents or the Indenture; (9) to
      conform the text of the Indenture, the Note Guarantees, the Intercreditor
      Agreement, the other Security Documents or the Notes to any provision of
      the "Description of Senior Secured Notes" section of the Offering Circular
      dated May 12, 2004, to the extent that such provision in that "Description
      of Senior Secured Notes" was intended to be a verbatim recitation of a
      provision of the Indenture, the Note Guarantees, the Intercreditor
      Agreement, the other Security Documents or the Notes; (10) to comply with
      Sections 5.01 and 4.10 of the Indenture; (11) to reflect any waiver or
      termination of any right arising under the provisions of the Intercreditor
      Agreement that otherwise would be enforceable by any holder of a Credit
      Facility Lien, if such waiver or termination is set forth or provided in
      the Indenture, any of the Security Documents or the agreement governing or
      giving rise to such Credit Facility Lien, provided that no such waiver or
      amendment pursuant to this clause (11) shall adversely affect the rights
      of Holders of the Notes; and (12) to release Collateral constituting
      Excluded Securities in accordance with the conditions set forth in the
      definition of Excluded Assets in the Indenture.

            (13) DEFAULTS AND REMEDIES. Events of Default include: (i) default
      for 30 days in the payment when due of interest on, or Liquidated Damages,
      if any, with respect to the Notes; (ii) default in the payment when due
      (at maturity, upon redemption or otherwise) of the principal of, or
      premium, if any, on, the Notes, (iii) failure by the Company to comply
      with its obligations under Sections 4.10, 4.15, 4.21 or 5.01 of the
      Indenture; (iv) failure by the Company or any of its Restricted
      Subsidiaries for 30 days after written notice by the Trustee or the

      to comply with the provisions of Sections 4.07 and 4.09 of the Indenture,
      (v) failure by the Company or any of its Restricted Subsidiaries for 60
      days after notice to the Company by the Trustee or the Holders of at least
      25% in aggregate principal amount of the Notes then outstanding (including
      Additional Notes, if any) voting as a single class to comply with any of
      the other agreements in the Indenture, the Escrow Agreement, the Notes, or
      the Security Documents; (vi) default under certain other agreements
      relating to Indebtedness of the Company or any of its Restricted
      Subsidiaries which default is either (a) a Payment Default or (b) results
      in the acceleration of such Indebtedness prior to its express maturity,
      and, in each case, the principal amount of such Indebtedness aggregates at
      least $15.0 million; (vii) certain final judgments for the payment of
      money that remain undischarged for a period of 60 days and aggregate in
      excess of $15.0 million; (viii) the Escrow Agreement or any other Security
      Document or any Lien purported to be granted thereby on the Escrow Account
      or the cash therein, the Eurobond Escrow Agreement or any other security
      document or any Lien purposed to be granted thereby on the Eurobond Escrow
      Account or the cash therein, or any one or more other items of Collateral
      having an aggregate fair market value in excess of $15.0 million is held
      in any judicial proceeding to be unenforceable or invalid, in whole or in
      part, or ceases for any reason (other than pursuant to a release that is
      delivered or becomes effective as set forth in the indenture) to be fully
      enforceable and perfected; provided that if the holders of the Series B
      Notes and the common stock into which the Series A Notes were converted
      waive the requirement in the Note Purchase Agreement for the establishment
      of the Eurobond Escrow Account, then the failure to establish the Eurobond
      Escrow Account or execute the Eurobond Escrow Agreement (or the
      termination of the Eurobond Escrow Agreement and dissolution of the
      Eurobond Escrow

                                      A2-7

      Account) shall not be deemed an Event of Default; (ix) the Company or any
      Guarantor denies or disaffirms, in writing in any pleading in any court of
      competent jurisdiction, any obligation of the Company or any Guarantor set
      forth in or arising under any Security Document; and (x) except as
      permitted by the Indenture, any Note Guarantee is held in any judicial
      proceeding to be unenforceable or invalid or shall cease for any reason to
      be in full force and effect and such default continues for 10 days after
      notice by the Trustee or the Holders of at least 25% in aggregate
      principal amount of the Notes then outstanding (including Additional
      Notes, if any) voting as a single class or any Guarantor or any Person
      acting on its behalf denies or disaffirms its obligations under such
      Guarantor's Note Guarantee and (xi) certain events of bankruptcy or
      insolvency with respect to the Company or any of its Restricted
      Subsidiaries that is a Significant Subsidiary or any group of Restricted
      Subsidiaries that, taken together, would constitute a Significant
      Subsidiary. If any Event of Default occurs and is continuing, the Trustee
      or the Holders of at least 25% in aggregate principal amount of the then
      outstanding Notes may declare all the Notes to be due and payable
      immediately. Notwithstanding the foregoing, in the case of an Event of
      Default arising from certain events of bankruptcy or insolvency, all
      outstanding Notes will become due and payable immediately without further
      action or notice. Holders may not enforce the Indenture or the Notes
      except as provided in the Indenture. Subject to certain limitations,
      Holders of a majority in aggregate principal amount of the then
      outstanding Notes may direct the Trustee in its exercise of any trust or
      power. The Trustee may withhold from Holders of the Notes notice of any
      continuing Default or Event of Default (except a Default or Event of
      Default relating to the payment of principal or interest or premium or
      Liquidated Damages, if any,) if it determines that withholding notice is
      in their interest. The Holders of a majority in aggregate principal amount
      of the then outstanding Notes by notice to the Trustee may, on behalf of
      the Holders of all of the Notes, rescind an acceleration or waive any
      existing Default or Event of Default and its consequences under the
      Indenture except a continuing Default or Event of Default in the payment
      of interest or premium or Liquidated Damages, if any, on, or the principal
      of, the Notes (other than non-payment of amounts that became due solely
      because of acceleration of the Notes). The Company is required to deliver
      to the Trustee annually a statement regarding compliance with the
      Indenture, and the Company is required, upon becoming aware of any Default
      or Event of Default, to deliver to the Trustee a statement specifying such
      Default or Event of Default.

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

            (15) NO RECOURSE AGAINST OTHERS. No director, officer, employee,
      incorporator or stockholder of the Company or any Guarantor, as such, will
      have any liability for any obligations of the Company or the Guarantors
      under the Notes, the indenture, the Note Guarantees, the Intercreditor
      Agreement, the Security Documents or for any claim based on, in respect
      of, or by reason of, such obligations or their creation. Each Holder of
      Notes by accepting a Note waives and releases all such liability. The
      waiver and release are part of the consideration for issuance of the
      Notes. The waiver may not be effective to waive liabilities under the
      federal securities laws and its is the view of the Commission that such a
      waiver is against public policy.

            (16) AUTHENTICATION. This Note will not be valid until authenticated
      by the manual signature of the Trustee or an authenticating agent.

            (17) ABBREVIATIONS. Customary abbreviations may be used in the name
      of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN
      ENT (= tenants by the entireties),

                                      A2-8

      JT TEN (= joint tenants with right of survivorship and not as tenants in
      common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

            (18) ADDITIONAL RIGHTS OF HOLDERS. In addition to the rights
      provided to Holders of Notes under the Indenture, Holders of Restricted
      Global Notes and Restricted Definitive Notes will have all the rights set
      forth in the Registration Rights Agreement dated as of May 26, 2004,
      between the Company and the other parties named on the signature pages
      thereof or, in the case of Additional Notes, Holders of Restricted Global
      Notes and Restricted Definitive Notes will have the rights set forth in
      one or more registration rights agreements, if any, among the Company, the
      Guarantors and the other parties thereto, relating to rights given by the
      Company and the Guarantors to the purchasers of any Additional Notes
      (collectively, the "Registration Rights Agreement").

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

            (20) GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL
      GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE
      GUARANTEES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF
      LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION
      WOULD BE REQUIRED THEREBY.

      The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture and/or the Registration Rights Agreement.

________________, 200__, among __________________ (the "Guaranteeing
Subsidiary"), a subsidiary of Milcaron Escrow Corporation (or its permitted
successor), a Delaware corporation (the "Company"), the Company, the other
Guarantors (as defined in the Indenture referred to herein) and U.S. Bank
National Association, as trustee under the Indenture referred to below (the
"Trustee").

                               W I T N E S S E T H

      WHEREAS, the Company has heretofore executed and delivered to the Trustee
an indenture (the "Indenture"), dated as of May __, 2004 providing for the
issuance of ___% Senior Secured Notes due 2011 (the "Notes");

      WHEREAS, the Indenture provides that under certain circumstances the
Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental
indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally
guarantee all of the Company's Obligations under the Notes and the Indenture on
the terms and conditions set forth herein (the "Note Guarantee"); and

      WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

      NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the
Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the
equal and ratable benefit of the Holders of the Notes as follows:

      1. CAPITALIZED TERMS. Capitalized terms used herein without definition
shall have the meanings assigned to them in the Indenture.

      2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to
provide an unconditional Guarantee on the terms and subject to the conditions
set forth in the Note Guarantee and in the Indenture including but not limited
to Article 11 thereof.

      3. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator, stockholder or agent of the Guaranteeing
Subsidiary, as such, shall have any liability for any obligations of the Company
or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the
Intercreditor Agreement the Security Documents, the Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of the Notes by accepting a
Note waives and releases all such liability. The waiver and release are part of
the consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such a waiver is against public policy.

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

      5. COUNTERPARTS. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them

whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
