         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

         in any proceeding under any Bankruptcy Law) on overdue installments of
         interest (without regard to any applicable grace periods) from time to
         time on demand at the same rate to the extent lawful. Interest shall be
         computed on the basis of a 360-day year of twelve 30-day months.

         except as provided in Section 2.12 of the Indenture with respect to
         defaulted interest. The Notes shall be payable as to principal,
         interest and premium at the office or agency of the Paying Agent within
         the City and State of New York, or, at the option of the Issuers,
         payment of interest 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 shall be required with

         Guarantors and the Trustee. The terms of the Notes include those stated
         in the Indenture and those made part of the Indenture by reference to

         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

         Equity Offerings by a direct or indirect parent of the Company (in each
         case, other than Excluded Contributions and the net proceeds of a sale
         of Designated Preferred Stock); provided that (i) at least 65% in
         aggregate principal amount of the Notes originally issued under the
         Indenture (excluding Notes held by the Company and its Subsidiaries)
         remains outstanding immediately after the occurrence of such
         redemption; and (ii) the redemption occurs within 90 days of the date
         of the closing of such Equity Offering or equity contribution.

                  (6) MANDATORY REDEMPTION. The Issuers shall not be required to
         make mandatory redemption payments with respect to the Notes.

                  (7) REPURCHASE AT THE OPTION OF HOLDER.

                  (a) If there is a Change of Control, each Holder shall have
         the right to require the Issuers to make an offer (a "Change of Control
         Offer") to repurchase all or any part (equal to $1,000 or an integral
         multiple of $1,000) of that Holder's Notes at a purchase price equal to
         101% of the aggregate principal amount thereof plus accrued and unpaid
         interest on the Notes repurchased, if any, to the date of purchase,
         subject to the rights of the Holders on the relevant record date to
         receive interest due on the relevant Interest Payment Date (the "Change
         of Control Payment"). Within 30 days following any Change of Control,
         the Issuers shall 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 10 Business Days of each date on
         which the aggregate amount of Excess Proceeds exceeds $15.0 million,
         the Company shall commence an Asset Sale Offer to all Holders and if
         the Company elects (or is required by the terms of such other pari
         passu indebtedness) all holders of other Indebtedness that is pari
         passu with the Notes pursuant to Section 3.09 of the Indenture to
         purchase the maximum principal amount of Notes and other pari passu
         Indebtedness 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 to the Purchase Date in
         accordance with


                                       4
<PAGE>

         the procedures set forth in the Indenture. To the extent that the
         aggregate amount of Notes and other pari passu Indebtedness tendered
         pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
         Company (or such Restricted Subsidiary) may use the remaining Excess
         Proceeds for any purpose not otherwise prohibited by the Indenture. If
         the aggregate principal amount of Notes and other pari passu
         Indebtedness surrendered by holders thereof exceeds the amount of
         Excess Proceeds, the Trustee shall select the Notes and other pari
         passu Indebtedness to be purchased on a pro rata basis. Holders to whom
         an Asset Sale Offer is addressed shall receive an Asset Sale Offer from
         the Company prior to the 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.

                  (8) NOTICE OF REDEMPTION. Notice of redemption shall be mailed
         at least 30 days but not more than 60 days before the redemption date
         to each Holder whose Notes are to be redeemed at its registered
         address, 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 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 redemption date
         interest ceases to accrue on Notes or portions thereof called for
         redemption.

                  (9) 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 Issuers may
         require a Holder to pay any taxes and fees required by law or permitted
         by the Indenture. The Issuers 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 Issuers 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.

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

                  (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
         exceptions, the Indenture, the Subsidiary Guarantees or the Notes 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,

         "Payment Default") or (b) results in the acceleration of such
         Indebtedness prior to its express maturity, and, in each case, the

         acceleration of such Indebtedness under the Credit Facilities or (2)
         five Business Days after receipt by the Company of written notice of
         such acceleration. Notwithstanding the foregoing, in the case of an
         Event of Default arising from certain events of bankruptcy or
         insolvency, all outstanding Notes shall become due and payable without
         further action or notice. Holders may not enforce the Indenture or the
         Notes except as provided in the Indenture. Subject to certain
         limitations, Holders of a majority in principal amount of the then
         outstanding Notes may direct the Trustee in its exercise of any trust
         or power. The Trustee may withhold from Holders notice of any
         continuing Default or Event of Default (except a Default or Event of
         Default relating to the payment of principal or interest) if it
         determines that withholding notice is in their interest. The Holders of
         a majority in aggregate principal amount of the Notes then outstanding
         by notice to the Trustee may on behalf of the Holders of all of the
         Notes waive any existing Default or Event of Default and its
         consequences under the Indenture except a continuing Default or Event
         of Default in the payment of the principal of, premium or interest on,
         the Notes (including in connection with an offer to purchase). 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.

                  (13) SUBORDINATION. All Obligations in respect of the Notes
         are subordinated to the prior payment in full in cash of all Senior
         Debt of the Issuers (whether outstanding on the Issue Date or created,
         incurred, assumed or guaranteed thereafter) on the terms provided in
         the Indenture.

                  (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. A director, officer,
         employee, incorporator, stockholder or member of the Issuers or any of
         the Guarantors, as such, shall not have any liability for any
         obligations of the Issuers or such Guarantor under the Notes, the
         Subsidiary Guarantees or the Indenture or for any claim based on, in
         respect of, or by reason of, such obligations or their creation. Each
         Holder by accepting a Note waives and releases all such liability. The
         waiver and release are part of the consideration for the issuance of
         the Notes.

         authenticating agent.

                  (17) ABBREVIATIONS. Customary abbreviations may be used in the

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

without charge a copy of the Indenture and/or the Registration Rights Agreement.
