     Optional Conversion. The Convertible Notes may be converted at any time by a holder into shares of the Company’s common stock at a conversion rate of 68.5589 per $1,000 principal amount of notes, subject to certain adjustments, which represents an initial conversion price of approximately $14.59 per share.
     Mandatory Redemption.

Definitions. "Acquired Debt" means, with respect to any specified Person, (i) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Subsidiary of, such specified Person, and (ii) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. "Affiliate" of any specified Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, "control," as used with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise; provided that beneficial ownership of 10% or more, or an agreement, obligation or option to purchase 10% or more, of the Voting Stock of a Person shall be deemed to be control.

"Applicable Procedures" means, with respect to any transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of the Depositary.

Such present value shall be calculated using a discount rate equal to the rate of interest implicit in such transaction, determined in accordance with GAAP. "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. "Beneficial Owner" has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership of any particular "person" (as such term is used in Section 13(d)(3) of the Exchange Act), such "person" shall be deemed to have beneficial ownership of all securities that such "person" has the right to acquire, whether such right is currently exercisable or is exercisable only upon the occurrence of a subsequent condition. "Board of Directors" means the Board of Directors of the Company, or any authorized committee of the Board of Directors.

"Business Day" means any day other than a Legal Holiday. "Capital Lease Obligation" means, at the time any determination thereof is to be made, the amount of the liability in respect of a capital lease that would at that time be required to be capitalized on a balance sheet in accordance with GAAP.

Section 3.02. Selection of Notes to Be Redeemed. If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select the Notes to be redeemed or purchased among the Holders of the Notes in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot or in accordance with any other method the Trustee considers fair and appropriate. In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption. 22

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. Section 3.03. Notice of Redemption 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 shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. The notice shall identify the Notes to be redeemed and shall state: (a) the redemption date; (b) the redemption price; (c) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note; (d) the name and address of the Paying Agent; (e) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; (f) 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; (g) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and (h) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. At the Company's request, the Trustee shall give the notice of redemption in the Company's name and at its expense; provided, however, that the Company shall have delivered to the Trustee, at least 45 days (or such shorter period as may be acceptable to the Trustee) prior to the redemption date, an Officers' Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in 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. A notice of redemption may not be conditional. 23

Section 3.05. Deposit of Redemption Price. Prior to 10:00 a.m. Eastern Time on the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed. If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. Section 3.06. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall issue and, upon the Company's written request, the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered. Section 3.07. Optional Redemption. (a) Except as set forth in paragraphs, (c) and (d) below, the Notes will not be redeemable at the option of the Company prior to June 1, 2011. (b) At any time on or after June 1, 2011, the Notes may be redeemed at the redemption prices set forth below, plus accrued and unpaid interest to but excluding the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

The Asset Sale Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the "Offer Period"). No later than five Business Days after the termination of the Offer Period (the "Purchase Date"), the Company shall purchase the principal amount of Notes required to be purchased pursuant to Section 4.10 hereof and such other Indebtedness that is pari passu with the Notes containing provisions similar to Section 4.10 hereof that may be purchased out of the Excess Proceeds (the "Offer Amount") or, if less than the Offer Amount has been tendered, all Notes tendered in response to the Asset Sale Offer. Payment for any Notes so purchased shall be made in the same manner as interest payments are made. If the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest shall be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest shall be payable to Holders who tender Notes pursuant to the Asset Sale Offer. Upon the commencement of an Asset Sale Offer, the Company shall send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The Asset Sale Offer shall be made to all Holders.

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

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 shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. The 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 Borough of Manhattan, The City of New York for such purposes.

(c) The Company shall, so long as any of the Notes are outstanding, 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.

Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Company and any Restricted Subsidiary that is a Guarantor may incur Indebtedness (including Acquired Debt), and the Company may issue Disqualified Stock, and any Restricted Subsidiary that is a Guarantor may issue preferred stock, if the Consolidated Interest Expense Coverage Ratio for the Company's most recently ended four full fiscal quarters (the "Reference Period") 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 Disqualified Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period. The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, "Permitted Debt"): (i) the incurrence by the Company and any Restricted Subsidiary of any Permitted Bank Debt; provided that the aggregate principal amount of all Permitted Bank Debt at any one time outstanding shall not exceed $100.0 million plus 85% of the consolidated accounts receivable of the Company plus 50% of the consolidated inventory of the Company; (ii) the incurrence by the Company and its Subsidiaries of Existing Indebtedness; (iii) the incurrence by the Company and any Guarantor of Indebtedness represented by the Notes and any Note Guarantees; (iv) the incurrence by the Company or any of its Restricted Subsidiaries of (a) Indebtedness incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries and (b) Capital Lease Obligations, in an aggregate amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (iv), not to exceed the greater of $75.0 million and 10% of the Company's Consolidated Net Assets; (v) the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace, Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under the first paragraph of this covenant or clauses (ii), (iii), (v), (xiii) or (xiv) of this paragraph; (vi) the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that: (a) if the Company or any Guarantor is the obligor on such Indebtedness and such Indebtedness is in favor of a Restricted Subsidiary other than a Wholly Owned Restricted Subsidiary, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes in the case of the Company, or the Note Guarantee and of such Guarantor, in the case of a Guarantor, and (b)(I) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Wholly Owned Restricted Subsidiary thereof and (II) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Wholly Owned Restricted Subsidiary thereof; shall be deemed, in each case, to constitute an 32

incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi); (vii) the incurrence by the Company or any of its Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate, commodity or currency risk in the ordinary course of business for bona fide hedging purposes; provided that the notional principal amount of any such Hedging Obligation with respect to interest rates does not exceed the amount of Indebtedness or other liability to which such Hedging Obligation relates; (viii) the Guarantee by the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by another provision of this Section 4.09; (ix) the incurrence by the Company's Unrestricted Subsidiaries of Non-Recourse Debt; provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary, such event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was not permitted by this clause (ix); (x) the incurrence of Indebtedness solely in respect of performance, surety and similar bonds or completion or performance Guarantees, to the extent that such incurrence does not result in the incurrence of any obligation for the payment of borrowed money to others; (xi) the incurrence of Indebtedness arising from the agreements of the Company or a Restricted Subsidiary of the Company providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or a Subsidiary; provided, however, that: (a) such Indebtedness is not reflected as a liability on the balance sheet of the Company or any Restricted Subsidiary of the Company, and (b) the maximum assumable liability in respect of all such Indebtedness shall at no time exceed the gross proceeds, including non-cash proceeds (the fair market value of such non-cash proceeds being measured at the time received and without giving effect to any subsequent changes in value), actually received by the Company and its Restricted Subsidiaries in connection with such disposition; (xii) the accrual of interest, accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock; provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of the Company as accrued; (xiii) the incurrence of Indebtedness by Foreign Subsidiaries in an amount not to exceed 10% of the Total Tangible Assets of the Foreign Subsidiaries, taken as a whole; and (xiv) the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (xiv), not to exceed $50.0 million. Indebtedness or preferred stock of any Person which is outstanding at the time such Person becomes a Restricted Subsidiary of the Company (including upon designation of any Subsidiary or other Person as a Restricted Subsidiary) or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company shall be deemed to have been incurred at the time such Person 33

becomes such a Restricted Subsidiary of the Company or is merged with or into or consolidated with the Company or a Restricted Subsidiary of the Company, as applicable. The Company will not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company 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 shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by virtue of any Liens, Guarantees, maturity of payments of structural seniority. For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xiv) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company may, in its sole discretion, classify or reclassify such of Indebtedness (or any part thereof) in any manner that complies with this Section 4.09 and such item of Indebtedness shall be treated as having been incurred pursuant to only one of such clauses or pursuant to the first paragraph of this Section 4.09. For purposes of determining any particular amount of Indebtedness under this covenant, Guarantees, Liens or obligations in support of letters of credit supporting Indebtedness shall not be included to the extent such letters of credit are included in the amount of such Indebtedness. Any increase in the amount of any Indebtedness solely by reason of currency fluctuations shall not be considered an incurrence of Indebtedness for purposes of this covenant. Accrual of interest and the payment of interest in the form of additional Indebtedness shall not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09. Section 4.10. Asset Sales. The Company shall not, and shall not permit any of its Restricted Subsidiaries to: (i) sell, lease, convey or otherwise dispose of any assets or rights (including by way of a sale-and-leaseback) other than sales of inventory in the ordinary course of business (provided that the sale, lease, conveyance or other distribution of all or substantially all of the assets of the Company and its Restricted Subsidiaries, taken as a whole, shall be governed by the provisions of Sections 4.14 and 5.01 hereof and not by the last paragraph of this section), or (ii) with respect to the Company, sell Equity Interests in any of its Subsidiaries, or (iii) with respect to the Company's Restricted Subsidiaries, issue Equity Interests (each of the foregoing, an "Asset Sale"), unless (x) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the fair market value (evidenced by a resolution of the Board of Directors set forth in an Officers' Certificate delivered to the Trustee) of the assets sold or otherwise disposed of and (y) at least 75% of the consideration received therefor by the Company or such Restricted Subsidiary is in the form of cash or other Qualified Proceeds. Notwithstanding the foregoing, the following shall not be deemed to be Asset Sales: (i) any single transaction or series of related transactions that (a) involves assets having a fair market value of less than $2.0 million or (b) results in net proceeds to the Company and its Restricted Subsidiaries of less than $2.0 million, (ii) a transfer of assets between or among the Company and any Restricted Subsidiary, (iii) an issuance of Equity Interests by a Restricted Subsidiary to the Company or to another Wholly Owned Restricted Subsidiary, (iv) the sale, lease, conveyance or other disposition of any Receivable Program Assets by the Company or any Restricted Subsidiary in connection with a Receivables Program, (v) the sale, lease, conveyance or other disposition of any inventory, receivables or other current assets by the Company or any of its Restricted Subsidiaries in the ordinary course of business, (vi) the granting of a 34

Permitted Lien, (vi) the licensing by the Company or any Restricted Subsidiary of intellectual property in the ordinary course of business or on commercially reasonable terms, (vii) the sale, lease, conveyance or other disposition of obsolete or worn out equipment or equipment no longer useful in the Company's business, and (viii) the making or liquidating of any Restricted Payment or Permitted Investment that is permitted by Section 4.07 hereof. Within 365 days after the receipt of any Net Proceeds from any Asset Sale, the Company (or such Restricted Subsidiary) may apply such Net Proceeds from such Asset Sale, at its option, either (a) to repay Permitted Bank Debt, and if such Permitted Bank Debt is revolving debt, to effect a corresponding commitment reduction thereunder, (b) to acquire all or substantially all of the assets of, or a majority of the Voting Stock of, another Permitted Business, (c) to make a capital expenditure, or (d) to acquire any other long-term assets that are used or useful in a Permitted Business. Pending the final application of any such Net Proceeds, the Company (or such Restricted Subsidiary) may temporarily reduce revolving credit borrowings or otherwise invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from such Asset Sale that are not finally applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds." Within five days of each date on which the aggregate amount of Excess Proceeds exceeds $10 million, the Company shall commence a pro rata Asset Sale Offer pursuant to Section 3.09 hereof to purchase the maximum principal amount of 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 to the date fixed for the closing of such offer, in accordance with the procedures set forth in Section 3.09 hereof. To the extent that the aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Subsidiary) may use such deficiency for any purpose not otherwise prohibited by this Indenture. Upon completion of such offer to purchase, the amount of Excess Proceeds will be deemed to be reset at zero. Section 4.11. Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an "Affiliate Transaction"), unless: (a) such Affiliate Transaction (when viewed together with related Affiliate Transactions, if any) is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person, and (b) the Company delivers to the Trustee (i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with this covenant and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors (of which there must be at least one), and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, an opinion as to the fairness to the Holders of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. The following items shall not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraphs: (a) any employment agreement or arrangement entered into by the Company or any of its Restricted Subsidiaries or any employee benefit plan available to employees of the Company and its 35

Subsidiaries generally, in each case in the ordinary course of business and consistent with the past practice of the Company or such Restricted Subsidiary; (b) Affiliate Transactions between or among the Company and/or its Restricted Subsidiaries; (c) payment of reasonable directors fees to Persons who are not otherwise Affiliates of the Company and indemnity provided on behalf of officers, directors and employees of the Company or any of its Restricted Subsidiaries as determined in good faith by the Board of Directors of the Company; and (d) any Restricted Payments that are permitted by Section 4.07 hereof. For purposes of this Section 4.11, any transaction or series of related Affiliate Transactions between the Company or any Restricted Subsidiary and an Affiliate that is approved by a majority of the disinterested members of the Board of Directors (of which there must be at least one to utilize this method of approval) and evidenced by a board resolution or for which a fairness opinion has been issued shall be deemed to be 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 thus shall be permitted under this Section 4.11. Section 4.12. Liens. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind securing Indebtedness on any asset now owned or hereafter acquired, except Permitted Liens, unless the Notes or any existing Note Guarantee of a Subsidiary subject to such Lien are equally and ratably secured with the obligations so secured for as long as such Indebtedness will be so secured. Section 4.13. Corporate Existence. Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect (i) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and (ii) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. Section 4.14. 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 thereof) of each Holder's Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to the date of purchase (the "Change of Control Payment"). Within 30 days following any Change of Control, the Company shall mail a notice to each Holder stating: (i) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment, (ii) the purchase price and the purchase date, which shall 36

be no later than 30 business days from the date such notice is mailed (the "Change of Control Payment Date"), (iii) that any Note not tendered will continue to accrue interest, (iv) 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, (v) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date, (vi) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased, and (vii) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof. The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes in connection with a Change of Control. (b) On the Change of Control Payment Date, the Company shall, to the extent lawful, (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so tendered, and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of Notes so tendered payment in an amount equal to the purchase price for the 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 by such Holder, if any; provided, that each such new Note shall be in a principal amount of $1,000 or an integral multiple thereof. 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 4.14, the Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 and Section 3.09 hereof and all other provisions of this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. Section 4.15. Limitation on Issuances and Sales of Capital Stock in Wholly Owned Subsidiaries. The Company (a) shall not, and shall not permit any of Wholly Owned Restricted Subsidiaries of the Company to, transfer, convey, sell, lease or otherwise dispose of any Equity Interests in any Wholly Owned Restricted Subsidiary of the Company to any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company), unless (i) such transfer, conveyance, sale, lease or other disposition is of all the Equity Interests in such Wholly Owned Restricted Subsidiary or immediately following such transfer, conveyance, sale, lease or other disposition, the Wholly Owned Restricted Subsidiary is a Restricted Subsidiary and (ii) the cash Net Proceeds from such transfer, conveyance, sale, lease or other disposition are applied in accordance with Section 4.10 hereof, and (b) shall not permit any Wholly Owned Restricted Subsidiary of the Company to issue any of its Equity Interests (other than, if necessary, shares of its Capital Stock constituting directors' qualifying shares) to 37

any Person other than to the Company or a Wholly Owned Restricted Subsidiary of the Company unless immediately following such issuance the Wholly Owned Restricted Subsidiary is a Restricted Subsidiary. Section 4.16. Payments for Consent. Neither the Company nor any of its Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of any 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 or is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. Section 4.17. Future Subsidiary Guarantees. If the Company or any of its Restricted Subsidiaries shall acquire, create or capitalize a Domestic Subsidiary after the date of this Indenture that is a Significant Subsidiary, then that newly acquired, created or capitalized Subsidiary must become a Guarantor and execute a supplemental indenture satisfactory to the Trustee and deliver an Opinion of Counsel, in accordance with the terms of this Indenture, to the Trustee within 10 Business Days of the date on which it was acquired or created. The form of such Supplemental Indenture is attached as Exhibit C hereto. Section 4.18. Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary so long as such designation would not cause a Default hereunder. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary so designated will be deemed to be an Investment made as of the time of such designation and will reduce the amount available for Restricted Payments under the first paragraph of Section 4.07 hereof or Permitted Investments, as applicable. All such outstanding Investments will be valued at their fair market value at the time of such designation. That designation will only be permitted if such Restricted Payment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default hereunder. Section 4.19. Limitation on Sale and Leaseback Transactions. The Company shall not, and shall not permit any of its 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 (i) the Company or such Restricted Subsidiary, as applicable, could have incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction (if the lease is in the nature of an operating lease, otherwise the amount of Indebtedness) under the Consolidated Interest Expense Coverage Ratio test in the first paragraph of Section 4.09 hereof, and (ii) the transfer of assets in that sale and leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof. The foregoing restrictions shall not apply to any sale and leaseback transaction if (i) the transaction is solely between the Company and any Restricted Subsidiary or between Restricted Subsidiaries, or (ii) the sale and leaseback transaction is consummated within 180 days after the purchase of the assets subject to such transaction. 38

ARTICLE 5 SUCCESSORS Section 5.01. Merger, Consolidation, or Sale of Assets. The Company shall not, directly or indirectly, consolidate or merge with or into another Person (whether or not the Company is the surviving corporation) or sell, assign, transfer, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to another Person, unless (i) the Company is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition shall have been made is a corporation organized or existing under the laws of the United States, any state thereof or the District of Columbia, (ii) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition shall have been made assumes all the obligations of the Company under the Notes and this Indenture pursuant to agreements reasonably satisfactory to the Trustee, (iii) immediately after such transaction no Default or Event of Default exists, (iv) except in the case of the amalgamation, consolidation or merger of the Company with or into a Wholly Owned Restricted Subsidiary or with or into any Person solely for the purpose of effecting a change in the state of incorporation of the Company, the Company or the Person formed by or surviving any such consolidation or merger (if other than the Company) shall, 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, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Expense Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof, and (v) the Company shall have delivered to the Trustee an Officer's Certificate stating that such consolidation, merger, sale, assignment, transfer, conveyance or other disposition complies with this Indenture. In addition, the Company shall not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. The provisions of this Section 5.01 shall not be applicable to a sale, assignment, transfer, conveyance or other disposition of assets by the Company to any of its Wholly Owned Restricted Subsidiaries. Section 5.02. Successor Corporation Substituted. Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the "Company" shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person 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 all of the Company's assets that meets the requirements of Section 5.01 hereof. ARTICLE 6 DEFAULTS AND REMEDIES Section 6.01. Events of Default. An "Event of Default" occurs if: 39

(a) the Company defaults in the payment when due of interest on the Notes and such default continues for a period of 30 days; (b) the Company defaults in the payment when due of principal of or premium, if any, on the Notes when the same becomes due and payable at maturity, upon redemption (including in connection with an offer to purchase) or otherwise; (c) the Company fails to make any payment required to be made pursuant to the provisions of Section 4.10 or 4.14 hereof; (d) the Company fails to observe or perform any other covenant, representation, warranty or other agreement in this Indenture or the Notes 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; (e) a default occurs 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, which default (i) is caused by a failure to pay principal of such Indebtedness at the Stated Maturity thereof or (ii) results in the acceleration of such Indebtedness prior to the Stated Maturity thereof, and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, aggregates $10 million or more; (f) a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary and such judgment or judgments remain undischarged for a period (during which execution shall not be effectively stayed) of 60 days, provided that the aggregate of all such undischarged judgments exceeds $10 million (other than amounts covered by insurance); (g) within the meaning of Bankruptcy Law, the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a custodian of it or for all or substantially all of its property, (iv) makes a general assignment for the benefit of its creditors, or (v) generally is not paying its debts as they become due; or (h) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 40

(i) is for relief against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary in an involuntary case; (ii) appoints a custodian of the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; or (iii) orders the liquidation of the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary; and the order or decree remains unstayed and in effect for 60 consecutive days. Section 6.02. Acceleration. If any Event of Default (other than an Event of Default specified in clause (g) or (h) of Section 6.01 hereof with respect to the Company, any Significant Subsidiary or any group of Significant Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (g) or (h) of Section 6.01 hereof occurs with respect to the Company, any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, all outstanding Notes shall be due and payable immediately without further action or notice. 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 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, 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 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 41

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 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 of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (e) during such 60-day period the Holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. Section 6.07. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. Section 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) 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 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. 42

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 other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and interest, respectively; and Third: to the Company or to such party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. Section 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes. 43

ARTICLE 7 TRUSTEE Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs.

(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities 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 or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. Section 7.04. Trustee's Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture 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 shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Section 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, 45

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. Within 60 days after each March 15 beginning with the March 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall 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 shall comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange. Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder, as the parties shall agree in writing from time to time. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company shall indemnify the Trustee 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 (including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. To secure the Company's payment obligations in this Section, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(g) or (h) hereof occurs, the expenses and the compensation for the services (including the 46

fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. Section 7.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 7.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (c) a custodian or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall 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 shall continue for the benefit of the retiring Trustee. 47

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 (including the trust created by this Indenture) to, another corporation, the successor corporation without any further act shall be the successor Trustee. Section 7.10. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has (or if the Trustee is a subsidiary of a bank holding company, its parent shall have) a combined capital and surplus of at least $100 million as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b). Section 7.11. Preferential Collection of Claims Against Company. The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. ARTICLE 8 LEGAL DEFEASANCE AND COVENANT DEFEASANCE Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. Section 8.02. Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Notes and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, interest on such Notes when such payments are due, (b) the Company's obligations with respect to such Notes under Article 2 and Section 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company's obligations in connection therewith and (d) this 48

Article Eight. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. Section 8.03. Covenant Defeasance. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18, 4.19 and 4.20 hereof and clause (iv) of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(c) through 6.01(f) hereof shall not constitute Events of Default. Section 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: In order to exercise either Legal Defeasance or Covenant Defeasance: (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be and the Company must specify whether the Notes are being defeased to maturity or to a particular redemption date; (b) in the case of an election under Section 8.02 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States 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 shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (c) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal 49

income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (d) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the incurrence of Indebtedness all or a portion of the proceeds of which will be used to defease the Notes pursuant to this Article 8 concurrently with such incurrence) or insofar as Sections 6.01(g) or 6.01(h) hereof is concerned, at any time in the period ending on the 91st day after the date of deposit; (e) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (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; (f) the Company shall have delivered to the Trustee an Opinion of Counsel (which may be subject to customary exceptions) to the effect that on the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; (g) the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; (h) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with; and (i) except as otherwise provided in this Indenture, each Guarantor shall have been released from its Obligations under its Note Guarantee. Section 8.05. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government 50

Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. Section 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. Section 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. ARTICLE 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, if any, and the Trustee may amend or supplement this Indenture, the Note Guarantees or the Notes without the consent of any Holder of a Note: (a) to cure any ambiguity, defect or inconsistency; (b) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; (c) to provide for the assumption of the Company's or a Guarantor's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 5 or Article 10 hereof; 51

(d) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note; (e) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; (f) to make any change necessary to make this Indenture, the Notes or the Notes Guarantee, as applicable, consistent with the disclosure under the caption "Description of Notes" in the final prospectus supplement relating to the initial issuance of the Notes; or (g) to permit any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company 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 shall not be obligated to enter into such amended or supplemental Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Section 9.02. With Consent of Holders of Notes. Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Sections 3.09, 4.10 and 4.14 hereof), the Note Guarantees and the Notes with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Note Guarantees or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including 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 shall join with the Company in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. 52

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes 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. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; (b) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and 4.14 hereof; (c) reduce the rate of or change the time for payment of interest, including default interest, on any Note; (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest 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); (e) make any Note payable in money other than that stated in the Notes; (f) 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 on the Notes; (g) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions; (h) waive a payment required by any of the covenants in 3.09, 4.10, 4.14; or (i) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture. Section 9.03. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental Indenture that complies with the TIA as then in effect. Section 9.04. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, 53

supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. Section 9.05. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. Section 9.06. Trustee to Sign Amendments, etc. The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental Indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 11.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. ARTICLE 10 NOTE GUARANTEES Section 10.01. Guarantee. Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (a) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof, and (b) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, 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 shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 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 54

a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 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 (y) 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) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. Section 10.02. 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, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. Section 10.03. Execution and Delivery of Note Guarantee. To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Note Guarantee substantially in the form included in Exhibit B shall be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture shall be executed on behalf of such Guarantor by its President or one of its Vice Presidents. Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 shall 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 shall be valid nevertheless. 55

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. In the event that the Company creates or acquires any new Subsidiaries subsequent to the date of this Indenture, if required by Section 4.18 hereof, the Company shall cause such Subsidiaries to execute supplemental indentures to this Indenture and Note Guarantees in accordance with Section 4.18 hereof and this Article 10, to the extent applicable. Section 10.04. Guarantors May Consolidate, etc., on Certain Terms. Except as otherwise provided in Section 10.05, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person whether or not affiliated with such Guarantor unless: (a) subject to Section 10.05 hereof, either: (i) the Surviving Person (if not a Guarantor or the Company) is a Restricted Subsidiary and expressly assumes all the obligations of that Guarantor under the Indenture and the Notes Guarantee by executing a supplemental indenture and other documents reasonably satisfactory to the Trustee; or (ii) such sale, transfer, assignment, conveyance or other disposition or merger, consolidation or amalgamation is otherwise in compliance with Section 4.10; and (b) immediately after giving effect to such transaction, no Default or Event of Default exists. In case of any such consolidation or merger 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 shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the 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 shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. Section 10.05. Release of Notes Guarantors. (a) A Notes Guarantor shall be released from all of its obligations under its Notes Guarantee and this Indenture: (i) in connection with any sale or other disposition of all or substantially all of the assets or all of the Capital Stock of that Notes Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Domestic Subsidiary of the Company, if such sale or other disposition is in compliance with Section 4.10; 56

(ii) upon the designation of such Guarantor as an Unrestricted Subsidiary, in accordance with the terms of this Indenture; (iii) upon the delivery by the Company to the Trustees of an Officers' Certificate certifying that such Guarantor is not a Significant Subsidiary or a Domestic Subsidiary; (iv) in the case of the Guarantors who Guarantee the Notes on the Issue Date, upon the release of a Guarantor from its Guarantee under the Existing Senior Notes and the 10 1/2% Senior Subordinated Notes due 2009; and in each case, the Company has delivered to the Trustee an Officers' Certificate, each stating that all conditions precedent herein provide for relating to such transactions have been complied with and that such release is authorized and permitted hereunder; and provided, that no release pursuant to clauses (ii) or (iii) above shall be effective unless and until such Guarantor ceases to be a guarantor under the Existing Senior Notes or Senior Subordinated Notes. (b) If all of the conditions to release contained in this Section 10.05 have been satisfied, the Trustee shall execute any documents reasonably requested by the Company or any Notes Guarantor in order to evidence the release of such Notes Guarantor from its obligations under its Notes Guarantee under this Article 10. Any Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

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. 5. OPTIONAL REDEMPTION. (a) Except as set forth in clauses (c) and (d) of this paragraph 5, the Notes will not be redeemable at the option of the Company prior to June 1, 2011. (b) At any time and from time to time on and after June 1, 2011, the Notes may be redeemed at the option of the Company at the redemption prices set forth below, plus accrued and unpaid interest to but excluding the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). The following redemption prices are for the Notes redeemed during the 12-month period commencing on June 1 of the years set forth below, and are expressed as percentages of principal amount: YEAR REDEMPTION PRICE - ---- ---------------- 2011 104.625% 2012 103.083% 2013 101.542% 2014 and thereafter 100.000% (c) At any time, and from time to time, prior to June 1, 2011, the Notes are subject to redemption, as a whole or in part, at the election of the Company, at a price equal to the sum of (i) 100% of the principal amount thereof plus accrued interest to the redemption date plus (ii) the Make-Whole Amount, if any.

Within 30 days following any Change of Control, the Company 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 Subsidiary consummates any Asset Sales, within five days of each date on which the aggregate amount of Excess Proceeds exceeds $10 million, the Company shall commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to Section 4.10 of the Indenture (as "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes and such 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 date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and such pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company (or such Subsidiary) may use such deficiency for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof plus the amount of any pari passu Indebtedness surrendered by the holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the 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" on the reverse of the Notes. 8.

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.

9. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 10. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture, the Note 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 voting as a single class, and any existing default or compliance with any provision of the Indenture, the Note Guarantees or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class. Without the consent of any Holder of a Note, the Indenture, the Note Guarantees or the Notes may be amended or supplemented to (i) to cure any ambiguity, defect or inconsistency; (ii) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 of the Indenture (including the related definitions) in a manner that does not materially adversely affect any Holder; (iii) to provide for the assumption of the Company's or a Guarantor's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 5 or Article 10 of the Indenture; (iv) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note; (v) to comply with requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA; (vi) to make any change necessary to make the Indenture, the Notes or the Notes Guarantee, as applicable, consistent with the disclosure under the caption "Description of Notes" in the final prospectus supplement relating to the initial issuance of the Notes; or (vii) to permit any Guarantor to execute a supplemental indenture and/or a Note Guarantee with respect to the Notes. Without the consent of each holder affected, an amendment or waiver may not (with respect to any Notes held by a nonconsenting holder): (i) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; (ii) reduce the principal of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes except as provided above with respect to Sections 3.09, 4.10 and 4.14 of the Indenture; (iii) reduce the rate of or change the time for payment of interest, including default interest, on any Note; (iv) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest 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); (v) make any Note payable in money other than that stated in the Notes; (vi) make any change in the provisions of the Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of or interest on the Notes; (vii) make any change in Section 6.04 or 6.07 of the Indenture or in the foregoing amendment and waiver provisions; (viii) waive a payment required by any of the covenants in Sections 3.09, 4.10, 4.14 of the Indenture; or (ix) release any Guarantor from any of its obligations under its Note Guarantee or the Indenture, except in accordance with the terms of the Indenture. 11. DEFAULTS AND REMEDIES. An "Event of Default" occurs if: (i) the Company defaults in the payment when due of interest on the Notes and such default continues for a period of 30 days; (ii) the Company defaults in the payment when due of principal of or premium, if any, on the Notes when the same becomes due and payable at maturity, upon redemption (including in connection with an offer to purchase) or otherwise; (iii) the Company fails to make any payment required to be made pursuant to the provisions of Section 4.10 or 4.14 of the Indenture; (iv) the Company fails to observe or perform any other covenant, representation, warranty or other agreement in the Indenture or the Notes 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; (v) a default occurs 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 A-5

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 the Indenture, which default (A) is caused by a failure to pay principal of such Indebtedness at the Stated Maturity thereof or (B) results in the acceleration of such Indebtedness prior to the Stated Maturity thereof, and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, aggregates $10 million or more; (vi) a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its Significant Subsidiaries or any group of Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary and such judgment or judgments remain undischarged for a period (during which execution shall not be effectively stayed) of 60 days, provided that the aggregate of all such undischarged judgments exceeds $10 million (other than amounts covered by insurance); and (vii) certain events of bankruptcy or insolvency with respect to the Company or any of its Significant Subsidiaries or any group of 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 principal amount of the then outstanding Notes may declare all the Notes to be due and payable. Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will 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 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) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal 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. 12. DESIGNATED SENIOR DEBT. This Note shall be "Designated Senior Debt" for purposes of the indentures governing the Company's 5.75% convertible subordinated notes due 2006, 5.00% convertible subordinated notes due 2007, 6.25% convertible subordinated notes due 2013 and the Senior Subordinated Notes. 13. GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THE NOTES 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. 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 or stockholder, of the Company, as such, shall not have any liability for any obligations of the Company under the Notes 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. A-6

EXHIBIT C FORM OF SUPPLEMENTAL INDENTURE TO BE DELIVERED BY SUBSEQUENT GUARANTORS SUPPLEMENTAL INDENTURE (this "Supplemental Indenture"), dated as of ________________, among __________________ (the "Guaranteeing Subsidiary"), a subsidiary of Amkor Technology, Inc. (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"). WITNESSETH WHEREAS, the Company has heretofore executed and delivered to the Trustee an indenture (the "Indenture"), dated as of May 26, 2006, governing the Company's 9.25% Senior Notes due 2016 (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 as follows: (a) Along with all Guarantors named in the Indenture, to jointly and severally Guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) 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 shall be jointly and severally obligated to pay the same immediately. C-1

(b) The obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the 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. (c) The following is hereby waived: 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. (d) This Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and the Indenture, and the Guaranteeing Subsidiary accepts all obligations of a Guarantor under the Indenture. (e) 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, shall be reinstated in full force and effect. (f) The Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. (g) As between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture 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 (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. (h) The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. (i) Pursuant to Section 10.02 of the Indenture, after giving effect to any maximum amount and any other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 10 of the Indenture, this Note Guarantee shall be limited to the maximum amount permissible such that the obligations of such Guarantor under this Note Guarantee will not constitute a fraudulent transfer or conveyance. 3. EXECUTION AND DELIVERY. Each Guaranteeing Subsidiary agrees that the Note Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. C-2

4. GUARANTEEING SUBSIDIARY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS. (a) Except as otherwise provided in Article 4 hereof and Section 10.05 of the Indenture, no Guarantor may consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person whether or not affiliated with such Guarantor unless: (a) subject to Article 4 hereof and Section 10.05 of the Indenture, either: (i) the Surviving Person (if not a Guarantor or the Company) is a Restricted Subsidiary and expressly assumes all the obligations of that Guarantor under the Indenture and the Notes Guarantee by executing a supplemental indenture and other documents reasonably satisfactory to the Trustee; or (ii) such sale, transfer, assignment, conveyance or other disposition or merger, consolidation or amalgamation is otherwise in compliance with Section 4.10 of the Indenture; and (b) immediately after giving effect to such transaction, no Default or Event of Default exists. In case of any such consolidation or merger 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 shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the 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 shall in all respects have the same legal rank and benefit under the Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. (c) Except as set forth in Articles 4 and 5 and Section 10.05 of Article 10 of the Indenture, and notwithstanding clauses (a) and (b) above, nothing contained in the Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. 5. RELEASES. (a) A Notes Guarantor shall be released from all of its obligations under its Notes Guarantee and the Indenture: (i) in connection with any sale or other disposition of all or substantially all of the assets or all of the Capital Stock of that Notes Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Domestic Subsidiary of the Company, if such sale or other disposition is in compliance with Section 4.10 of the Indenture; (ii) upon the designation of such Guarantor as an Unrestricted Subsidiary, in accordance with the terms of the Indenture; C-3

(iii) upon the delivery by the Company to the Trustees of an Officers' Certificate certifying that such Guarantor is not a Significant Subsidiary or a Domestic Subsidiary; (iv) in the case of the Guarantors who Guarantee the Notes on the Issue Date, upon the release of a Guarantor from its Guarantee under the Existing Senior Notes and the 10 1/2% Senior Subordinated Notes due 2009; and in each case, the Company has delivered to the Trustee an Officers' Certificate, each stating that all conditions precedent herein provide for relating to such transactions have been complied with and that such release is authorized and permitted hereunder; and provided, that no release pursuant to clauses (ii) or (iii) above shall be effective unless and until such Guarantor ceases to be a guarantor under the Existing Senior Notes or Senior Subordinated Notes. (b) Any Guarantor not released from its obligations under its Note Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under the Indenture as provided in Article 10 of the Indenture. 6. 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 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. 7. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 8. COUNTERPARTS The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement. 9. EFFECT OF HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof. 10. THE TRUSTEE. The Trustee shall not be responsible in any manner 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 recitals are made solely by the Guaranteeing Subsidiary and the Company.

Except as provided in Section 2.06 and 2.10, owners of beneficial interests in Global Securities will not be entitled to receive physical delivery of certificated Notes in definitive form. SECTION 2.02. Execution and Authentication. One Officer shall sign the Notes for the Company by manual or facsimile signature. 10

If an Officer whose signature is on a Note no longer holds that office at the time the Note is authenticated, the Note shall nevertheless be valid. A Note shall not be valid until authenticated by the manual signature of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. Upon a written order of the Company signed by an Officer of the Company, the Trustee shall authenticate Notes for original issue. The aggregate principal amount of Notes outstanding at any time may not exceed that amount except as provided in Section 2.07. The Notes shall be issuable only in registered form without coupons and only in denominations of $1,000 or any integral multiple thereof. 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 right as an Agent to deal with the Company or an Affiliate of the Company. SECTION 2.03. The Trustee Registrar, Paying Agent and Conversion Agent. The Company shall maintain or cause to be maintained in such locations as it shall determine, which may be the Corporate Trust Office, an office or agency: (i) where securities may be presented for registration of transfer or for exchange ("Registrar"); (ii) where Notes may be presented for payment ("Paying Agent"); (iii) an office or agency where Notes may be presented for conversion (the "Conversion Agent"); and (iv) where notices and demands to or upon the Company in respect of Notes and this Indenture may be served by the holders of the Notes. The Registrar shall keep a Register ("Register") of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars, one or more additional paying agents and one or more additional conversion agents. The term "Paying Agent" includes any additional paying agent and the term "Conversion Agent" includes any additional Conversion Agent. The Company may change any Paying Agent, Registrar, Conversion Agent or co-registrar without prior notice. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture and shall enter into an appropriate agency agreement with any Registrar, Paying Agent, Conversion Agent or co-registrar not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Company or any of its subsidiaries may act as Paying Agent, Registrar, Conversion Agent or co-registrar, except that for purposes of Articles III and VIII and Section 4.06, neither the Company nor any of its subsidiaries shall act as Paying Agent. If the Company fails to appoint or maintain another entity as Registrar, or Paying Agent or Conversion Agent, the Trustee shall act as such, and the Trustee shall initially act as such. SECTION 2.04. Paying Agent To Hold Money in Trust. The Company shall require each Paying Agent (other than the Trustee, who hereby so agrees), to agree in writing that the Paying Agent will hold in trust for the benefit of holders of the Notes or the Trustee all money held by the Paying Agent for the payment of principal or interest on the Notes, and will notify the Trustee of any default by the Company in respect of 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 of the Company) shall have no further liability for the money. If the Company or a Subsidiary of the Company acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the holders of the Notes all money held by it as Paying Agent. 11

SECTION 2.05. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of holders of Notes and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish to the Trustee at least seven Business Days before each Interest Payment Date, and as the Trustee may request in writing within fifteen (15) days after receipt by the Company of any such request (or such lesser time as the Trustee may reasonably request in order to enable it to timely provide any notice to be provided by it hereunder), a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of holders of Notes. SECTION 2.06. Transfer and Exchange. (a) When Notes are presented to the Registrar or a co-registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes for other denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Company shall issue and the Trustee shall authenticate Notes at the Registrar's request, bearing registration numbers not contemporaneously outstanding. No service charge shall be made to a holder for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the Company may require payment of a sum sufficient to cover any transfer tax or other governmental charge payable upon exchanges pursuant to Sections 2.10, 3.07, 9.05 or 12.02. The Company or the Registrar shall not be required to register the transfer of any Notes surrendered for repurchase pursuant to Section 4.06. All Notes issued upon any transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange. (b) Notwithstanding any provision to the contrary herein, so long as a Global Security remains outstanding and is held by or on behalf of the Depositary, transfers of a Global Security, in whole or in part, or of any beneficial interest therein, shall only be made in accordance with Section 2.10 and this Section 2.06(a). Except for transfers or exchanges made in accordance with paragraphs (i) through (iv) of this Section 2.06(b) and Section 2.10, transfers of a Global Security shall be limited to transfers of such Global Security in whole, but not in part, to nominees of the Depositary or to a successor of the Depositary or such successor's nominee. (i) Global Security To Definitive Security. If an owner of a beneficial interest in a Global Security deposited with the Depositary or with the Trustee as custodian for the Depositary wishes at any time to transfer its interest in such Global Security to a Person who is required to take delivery thereof in the form of a Definitive Security, such owner may, subject to the rules and procedures of the Depositary, cause the exchange of such interest for one or more Definitive Securities of any authorized denomination or denominations and of the same aggregate principal amount. Upon receipt by the Registrar of instructions from the Depositary directing the Trustee to authenticate and deliver one or more Definitive Securities of the same aggregate principal amount as the beneficial interest in the Global Security to be exchanged, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the Definitive Securities to be so issued and appropriate delivery instructions, then the Registrar will instruct the Depositary to reduce or cause to be reduced such Global Security by the aggregate principal amount of the beneficial interest therein to be exchanged and to debit or cause to be debited from the account of the Person making 12

such transfer the beneficial interest in the Global Security that is being transferred, and concurrently with such reduction and debit the Company shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities of the same aggregate principal amount in accordance with the instructions referred to above. (ii) Definitive Security to Definitive Security. If a holder of a Definitive Security wishes at any time to transfer such Definitive Security (or portion thereof) to a Person who is required to take delivery thereof in the form of a Definitive Security, such holder may, subject to the restrictions on transfer set forth herein and in such Definitive Security, cause the transfer of such Definitive Security (or any portion thereof in a principal amount equal to an authorized denomination) to such transferee. Upon receipt by the Registrar of (1) such Definitive Security, duly endorsed as provided herein, and (2) instructions from such holder directing the Trustee to authenticate and deliver one or more Definitive Securities of the same aggregate principal amount as the Definitive Security (or portion thereof) to be transferred, such instructions to contain the name or names of the designated transferee or transferees, the authorized denomination or denominations of the Definitive Securities to be so issued and appropriate delivery instructions, then the Registrar, shall cancel or cause to be canceled such Definitive Security and concurrently therewith, the Company shall execute, and the Trustee shall authenticate and deliver, one or more Definitive Securities in the appropriate aggregate principal amount, in accordance with the instructions referred to above and, if only a portion of a Definitive Security is transferred as aforesaid, concurrently therewith Company shall execute and the Trustee shall authenticate and deliver to the transferor a Definitive Security in a principal amount equal to the principal amount which has not been transferred. A holder of a Definitive Security may at any time exchange such Definitive Security for one or more Definitive Securities of other authorized denominations and in the same aggregate principal amount and registered in the same name by delivering such Definitive Security, duly endorsed as provided herein, to the Trustee together with instructions directing the Trustee to authenticate and deliver one or more Definitive Securities in the same aggregate principal amount and registered in the same name as the Definitive Security to be exchanged, and the Registrar thereupon shall cancel or caused to be canceled such Definitive Security and concurrently therewith the Company shall execute and Trustee shall authenticate and deliver, one or more Definitive Securities in the same aggregate principal amount and registered in the same name as the Definitive Security being exchanged. (iii) Definitive Security to Global Security. If a holder of a Definitive Security wishes at any time to transfer such Definitive Security (or portion thereof) to a Person who is not required to take delivery thereof in the form of a Definitive Security, such holder shall, subject to the restrictions on transfer set forth herein and in such Definitive Security and the rules of the Depositary cause the exchange of such Definitive Security for a beneficial interest in the Global Security. Upon receipt by the Registrar of (1) such Definitive Security, duly endorsed as provided herein, (2) instructions from such holder directing the Trustee to increase the aggregate principal amount of the Global Security deposited with the Depositary or with the Trustee as custodian for the Depositary by the same aggregate principal amount as the Definitive Security to be exchanged, such instructions to contain the name or names of a member of, or participant in, the Depositary that is designated as the transferee, the account of such member or participant and other appropriate delivery instructions, and (3) the assignment form on the back of the Definitive Security completed in full, then the Trustee shall cancel or cause to be canceled such Definitive Security and concurrently therewith shall increase the aggregate principal amount of the Global Security by the same aggregate principal amount as the Definitive Security canceled. (c) Neither the Trustee nor any Agent shall have any responsibility for any actions taken or not taken by the Depositary, 13

(d) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among Depositary's participants or beneficial owners of interests in any Global Security) other than to require delivery of such certificates and other documentation as is expressly required by, and to do so if and when expressly required by, the terms of this Indenture and to examine the same to determine substantial compliance as to form with the express requirements hereof. SECTION 2.07. Replacement Notes. If the holder of a Note claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the Trustee's requirements are met. If required by the Trustee or the Company as a condition of receiving a replacement Note, the holder of a Note must provide a certificate of loss and an indemnity and/or an indemnity bond sufficient, in the judgment of both the Company and the Trustee, to fully protect the Company, the Trustee, any Agent and any authenticating agent from any loss, liability, cost or expense which any of them may suffer or incur if the Note is replaced. The Company and the Trustee may charge the relevant holder for their expenses in replacing any Note. The Trustee or any authenticating agent may authenticate any such substituted Note, and deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. Upon the issuance of any substituted Note, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Note which has matured or is about to mature, or has been submitted for repurchase pursuant to Section 4.06 or is about to be converted into Common Stock pursuant to Article XII, shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to the authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any paying agent or conversion agent of the destruction, loss or theft of such Note and of the ownership thereof. Every replacement Note is an additional obligation of the Company and shall be entitled to all the benefits provided under this Indenture equally and proportionately with all other Notes duly issued, authenticated and delivered hereunder. SECTION 2.08. Outstanding Notes. The Notes outstanding at any time are all the Notes properly authenticated by the Trustee except for those canceled by the Trustee, those delivered to it for cancellation, and those described in this Section as not outstanding. If a Note is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser. If Notes are considered paid under Section 4.01 or converted under Article XII, they cease to be outstanding and interest on them ceases to accrue. Subject to Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 14

SECTION 2.09. When Treasury Notes Disregarded. In determining whether the holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or an Affiliate of the Company shall be considered as though they are not outstanding except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee knows are so owned shall be so disregarded. SECTION 2.10. Temporary Notes. (a) Until definitive Notes are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of definitive Notes but may have variations that the Company considers appropriate for temporary Notes and shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes. (b) Except for transfers made in accordance with Section 2.06(b), a Global Security deposited with the Depositary or with the Trustee as custodian for the Depositary pursuant to Section 2.01 shall be transferred to the beneficial owners thereof in the form of certificated Notes in definitive form only if such transfer complies with Section 2.06 and (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Security or if at any time such Depositary ceases to be a "clearing agency" registered under the Exchange Act and a successor Depositary is not appointed by the Company within 90 days of such notice, or (ii) an Event of Default has occurred and is continuing. (c) Any Global Security or interest thereon that is transferable to the beneficial owners thereof in the form of certificated Notes in definitive form shall, if held by the Depositary, be surrendered by the Depositary to the Trustee, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Global Security, an equal aggregate principal amount of Notes of authorized denominations in the form of certificated Notes in definitive form. Any portion of a Global Security transferred pursuant to this Section shall be executed, authenticated and delivered only in denominations of $1,000 and any integral multiple thereof and registered in such names as the Depositary shall direct. (d) Prior to any transfer pursuant to Section 2.10(b), the registered holder of a Global Security may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a holder is entitled to take under this Indenture or the Notes. (e) The Company will make available to the Trustee a reasonable supply of certificated Notes in definitive form without interest coupons. SECTION 2.11. Cancellation. The Company at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else may cancel Notes surrendered for registration of transfer, exchange, payment, replacement, conversion, repurchase or cancellation. Upon written instructions of the Company, the Trustee shall destroy and dispose of canceled Notes as the Company directs and, after such destruction, shall deliver a certificate of destruction to the Company. The Company may not issue new Notes to replace Notes that it has paid or repurchased or that have been delivered to the Trustee for cancellation or that any holder has (i) converted pursuant to Article XII hereof, or (ii) submitted for repurchase pursuant to Section 4.06 hereof (unless revoked). 15

SECTION 2.12. Defaulted Interest. If the Company fails to make a payment of interest on the Notes, it shall pay such defaulted interest plus, to the extent lawful, any interest payable on the defaulted interest. It may pay such defaulted interest, plus any such interest payable on it, to the Persons who are holders of Notes on a subsequent special record date. The Company shall fix any such special record date and payment date. At least 15 days before any such special record date, the Company shall mail to holders of the Notes a notice that states the special record date, payment date and amount of such interest to be paid. SECTION 2.13. CUSIP Number. The Company in issuing the Notes may use a "CUSIP" number, and if so, such CUSIP number shall be included in notices of repurchase or exchange as a convenience to holders of Notes; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes. The Company will promptly notify the Trustee of any change in the CUSIP number. ARTICLE III [INTENTIONALLY OMITTED] ARTICLE IV COVENANTS SECTION 4.01. Payment of Notes. The Company shall pay the principal of and interest on the Notes on the dates and in the manner provided in the Notes. Principal, interest or the Designated Event Payment shall be considered paid on the date due if the Trustee or Paying Agent (other than the Company or a Subsidiary of the Company) holds as of 10:00 a.m. New York City time on that date immediately available funds designated for and sufficient to pay all principal, interest and the Designated Event Payment then due; provided, however, that money held by the Agent for the benefit of holders of Senior Debt pursuant to the provisions of Article XI hereof or the payment of which to the holders of the Notes is prohibited by Article XI shall not be considered to be designated for the payment of any principal of or interest on the Notes within the meaning of this Section 4.01. To the extent lawful, the Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on (i) overdue principal, at the rate borne by Notes, compounded semiannually; and (ii) overdue installments of interest (without regard to any applicable grace period) at the same rate, compounded semiannually. SECTION 4.02. Commission Reports. Whether or not required by the rules and regulations of the Commission, so long as any Notes are outstanding, the Company will file with the Commission and furnish to the Trustee and the holders of Notes all quarterly and annual financial information (without exhibits) required to be contained in a filing with the Commission on Forms 10-Q and 10-K, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual consolidated financial statements only, a report thereon by the Company's independent auditors. The Company shall not be required to file any report or other information with the Commission if the Commission does not permit such filing, although such reports or other information will be required to be furnished to the Trustee. SECTION 4.03. Compliance Certificate. (a) The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company, a certificate of the principal executive officer, principal financial officer or principal accounting officer such officer's knowledge of the Company's compliance with all conditions and covenants under this Indenture (without regard to any period of grace or requirement of notice provided hereunder). 16

(b) The Company shall, so long as any of the Notes are outstanding, deliver to the Trustee, forthwith upon becoming aware of any Default or Event of Default, an Officers' Certificate specifying such Default or Event of Default. SECTION 4.04. Maintenance of Office or Agency. The Company shall maintain or cause to be maintained the office or agency required under Section 2.03. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not maintained by the Trustee. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, presentations, surrenders, notices and demands with respect to the Notes may be made 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 designation. SECTION 4.05. Continued Existence. Subject to Article V, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence. SECTION 4.06. Repurchase Upon Designated Event. Upon the occurrence of a Designated Event (the date of each such occurrence being the "Designated Event Date"), the Company shall be required to make an offer (the "Designated Event Offer") to repurchase all Notes then outstanding at a repurchase price in cash (the "Designated Event Payment") equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the Designated Event Payment Date (as defined below). Notice of a Designated Event shall be mailed by or at the direction of the Company to the holders of Notes as shown on the Register of such holders maintained by the Registrar not more than 20 days after the applicable Designated Event Date at the addresses as shown on the Register of holders maintained by the Registrar, with a copy to the Trustee and the Paying Agent. The Designated Event Offer shall remain open until a specified date (the "Designated Event Offer Termination Date") which is at least 20 Business Days from the date such notice is mailed. During the period specified in such notice, holders of Notes may elect to tender their Notes in whole or in part in integral multiples of $1,000 in exchange for cash. Payment shall be made by the Company in respect of Notes properly tendered pursuant to this Section on a specified Business Day (the "Designated Event Payment Date") which shall be no earlier than five Business Days after the applicable Designated Event Offer Termination Date and no later than 60 days after the applicable Designated Event. Unless and until the Trustee shall receive a notice of the occurrence of a Designated Event, the Trustee may assume without inquiry that none has occurred. The notice, which shall govern the terms of the Designated Event Offer, shall include such disclosures as are required by law and shall state: (a) that a Designated Event Offer is being made pursuant to this Section 4.06 and that all Notes will be accepted for payment; (b) the transaction or transactions that constitute the Designated Event; (c) the Designated Event Payment for each Note, the Designated Event Offer Termination Date and the Designated Event Payment Date; 17

(d) that any Note not accepted for payment will continue to accrue interest in accordance with the terms thereof; (e) that, unless the Company defaults on making the Designated Event Payment, any Note accepted for payment pursuant to the Designated Event Offer shall cease to accrue interest on the Designated Event Payment Date and no further interest shall accrue on or after such date; (f) that holders electing to have Notes repurchased pursuant to a Designated Event Offer will be required to surrender their Notes to the Paying Agent at the address specified in the notice prior to 5:00 p.m., New York City time, on the Designated Event Offer Termination Date and must complete any form letter of transmittal proposed by the Company and acceptable to the Trustee and the Paying Agent; (g) that holders of Notes will be entitled to withdraw their election if the Paying Agent receives, not later than 5:00 p.m., New York City time, on the Designated Event Offer Termination Date, a facsimile transmission or letter setting forth the name of the holder, the principal amount of Notes the holder delivered for purchase, the Note certificate number (if any) and a statement that such holder is withdrawing his election to have such Notes purchased; (h) that holders whose Notes are repurchased only in part will be issued Notes equal in principal amount to the unpurchased portion of the Notes surrendered; (i) the instructions that holders must follow in order to tender their Notes; and (j) that in the case of a Designated Event Offer Termination Date that is also an Interest Payment Date, the interest payment, if any, due on such Interest Payment Date shall be paid to the Person in whose name the Note is registered at the close of business on the relevant Designated Event Offer Termination Date. On the Designated Event Offer Termination Date the Company shall (i) accept for payment all Notes or portions thereof properly tendered pursuant to the Designated Event Offer, (ii) deposit with the Paying Agent money sufficient to pay the Designated Event Payment with respect to all Notes or portions thereof so tendered and accepted and (iii) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate setting forth the aggregate principal amount of Notes or portions thereof tendered to and accepted for payment by the Company. On the Designated Event Payment Date, the Paying Agent shall mail or deliver to the holders of Notes so accepted, the Designated Event Payment, and the Trustee shall promptly authenticate and mail or cause to be transferred by book entry to such holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered, if any; provided that such new Notes will be in a principal amount of $1,000 or an integral multiple thereof. Any Notes not so accepted shall be promptly mailed or delivered by the Company to the holder thereof. In the case of any reclassification, change, consolidation, merger, combination or sale or conveyance to which Section 12.06 applies, in which the Common Stock of the Company is exchanged as a result into the right to receive stock, securities or other property or assets (including cash) which includes shares of common stock of the Company or another Person that are, or upon issuance will be, traded on a United States national securities exchange or approved for trading on an established automated over-the-counter trading market in the United States and such shares constitute at the time such change or exchange becomes effective in excess of 50% of the aggregate fair market value of such stock, securities other property and assets (including cash) (as determined by the Company, which determination shall be conclusive and binding), then the Person formed by such consolidation or resulting from such 18

merger or which acquires such assets, as the case may be, shall execute and deliver to the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture) modifying the provisions of this Indenture relating to the right of holders of Notes to cause the Company to repurchase Notes following a Designated Event, including the applicable provisions of this Section 4.06 and the definitions of Designated Event, Change of Control and Termination of Trading, as appropriate, as determined in good faith by the Company (which determination shall be conclusive and binding), to make such provision apply to such common stock and the issuer thereof if different from the Company and Common Stock of the Company (in lieu of the Company and the Common Stock of the Company). The Designated Event Offer shall be made by the Company in compliance with all applicable provisions of the Exchange Act, and all applicable tender offer rules promulgated thereunder, to the extent such laws and regulations are then applicable and shall include all instructions and materials that the Company shall reasonably deem necessary to enable such holders of Notes to tender their Notes. SECTION 4.07. Appointments to Fill Vacancies in Trustee's Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.08, a Trustee, so that there shall at all times be a Trustee hereunder. SECTION 4.08. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter enforced, that may affect the Company's obligation to pay the Notes; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law insofar as such law applies to the Notes, 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 will suffer and permit the execution of every such power as though no such law has been enacted. SECTION 4.09. Taxes. The Company shall, and shall cause each of its subsidiaries to, pay prior to delinquency all taxes, assessments and government levies; provided, however, that the Company shall not be required to pay or cause to be paid any such tax, assessment or levy (A) if the failure to do so will not, in the aggregate, have a material adverse impact on the Company and its subsidiaries taken as a whole, or (B) if the amount, applicability or validity is being contested in good faith by appropriate proceedings. ARTICLE V SUCCESSORS SECTION 5.01. When the Company May Merge, Etc. The Company may not, in a single transaction or series of related transactions, consolidate or merge or combine with or into (whether or not the Company is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets to, any corporation as an entirety or substantially as an entirety unless: (a) either (i) the Company shall be the surviving or continuing corporation or (ii) the corporation formed by or surviving any such consolidation or merger or combination (if other than the Company) or the corporation which acquires by sale, assignment, transfer, 19

lease, conveyance or other disposition of all or substantially all of the properties and assets of the Company (1) shall be a corporation organized and validly existing under the laws of the United States or any State thereof or the District of Columbia and (2) shall expressly assume the due and punctual payment of the principal of, and premium, if any, and interest on, if any, with respect to, all the Notes and the performance of every covenant of the Company under the Notes and the Indenture, including, without limitation, modifications to rights of holders to cause the repurchase of Notes upon a Designated Event in accordance with the penultimate paragraph of Section 4.06 and conversion rights in accordance with Section 12.06 to the extent required by such Sections, pursuant to a supplemental indenture in a form reasonably satisfactory to the Trustee; (b) immediately after giving effect to such transaction no Default and no Event of Default exists; and (c) the Company or such Person shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with this provision of this Indenture and that all conditions precedent in this Indenture relating to such transaction have been satisfied. For purposes of this Section 5.01, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more subsidiaries of the Company, the capital stock of which constitutes all or substantially all of the properties and assets of the Company, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company. SECTION 5.02. Successor Corporation Substituted. Upon any such consolidation, merger, sale, assignment, conveyance, lease, transfer or other disposition in accordance with Section 5.01, the successor corporation formed by such consolidation or into which the Company is merged or to which such sale, assignment, conveyance, lease, transfer or other disposition is made will succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor had been named as the Company therein, and thereafter (except in the case of a sale, assignment, transfer, lease, conveyance or other disposition) the predecessor corporation will be relieved of all further obligations and covenants under this Indenture and the Notes. SECTION 5.03. Purchase Option on Change of Control. This Article V does not affect the obligations of the Company (including without limitation any successor to the Company) under Section 4.06. ARTICLE VI DEFAULTS AND REMEDIES SECTION 6.01. Events of Default. An "Event of Default" with respect to any Notes occurs if: (a) the Company defaults in the payment (whether or not such payment is prohibited by the subordination provisions set forth in Article XI of this Indenture) of principal of, or premium, if any, on the Notes when due at maturity, upon repurchase, upon acceleration or otherwise; or 20

(b) the Company defaults in the payment (whether or not such payment is prohibited by the subordination provisions set forth in Article XI of this Indenture) of any installment of interest on the Notes when due, including any interest payable in connection with a repurchase pursuant to Section 4.06, and continuance of such default for 30 days or more; or (c) the Company defaults (other than a default set forth in clauses (a) and (b) above and clauses (d) and (e) below) in the performance of, or breaches, any other covenant or warranty of the Company set forth in this Indenture or the Notes and fails to remedy such default or breach within a period of 60 days after the receipt of written notice from the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Notes; or (d) the Company defaults in the payment of the Designated Event Payment in respect of the Notes on the Designated Event Payment Date, whether or not such payment is prohibited by the subordination provisions set forth in Article XI of this Indenture; or (e) the Company fails to provide timely notice of any Designated Event in accordance with Section 4.06 hereof; or (f) failure of the Company or failure of any Material Subsidiary to make any payment at maturity, including any applicable grace period, in respect of indebtedness for borrowed money of, or guaranteed or assumed by, the Company or any Material Subsidiary, which payment is in an amount in excess of $20,000,000, and continuance of such failure for 30 days after notice thereof from the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Notes; or (g) default by the Company or default by any Material Subsidiary with respect to any indebtedness referred to in clause (f) above, which default results in the acceleration of any such indebtedness of an amount in excess of $20,000,000 without such indebtedness having been paid or discharged or such acceleration having been cured, waived, rescinded or annulled for 30 days after notice thereof from the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding Notes; or (h) the Company or any Material Subsidiary, pursuant to or within the meaning of Bankruptcy Law: (i) commences a voluntary case, (ii) consents to the entry of an order for relief against it in an involuntary case, (iii) consents to the appointment of a Custodian of it or for all or substantially all of its property, (iv) makes a general assignment for the benefit of its creditors; (v) makes the admission in writing that it generally is unable to pay its debts as the same become due; or (i) a court of competent jurisdiction enters a judgment, order or decree under any Bankruptcy Law that: (i) is for relief against the Company or any Material Subsidiary in an involuntary case, 21

(ii) appoints a Custodian of the Company or any Material Subsidiary, and the order or decree remains unstayed and in effect for 90 days. (iii) orders the liquidation of the Company or any Material Subsidiary, and the order or decree remains unstayed and in effect for 90 days. The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal or state law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default with respect to the Company specified in clauses (h) and (i) of Section 6.01) occurs and is continuing, then and in every such case the Trustee, by written notice to the Company, or the holders of at least 25% in aggregate principal amount of the then outstanding Notes, by written notice to the Company and the Trustee, may declare the unpaid principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Upon such declaration such principal amount, premium, if any, and accrued and unpaid interest, if any, shall become immediately due and payable, notwithstanding anything contained in this Indenture or the Notes to the contrary, but subject to the provisions of Article XI hereof. If any Event of Default with respect to the Company specified in clauses (h) or (i) of Section 6.01 occurs, all unpaid principal of and premium, if any, and accrued and unpaid interest, if any, on the Notes then outstanding shall become automatically due and payable subject to the provisions of Article XI hereof, without any declaration or other act on the part of the Trustee or any holder of Notes. The holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may rescind an acceleration of the Notes and its consequences if all existing Events of Default (other than nonpayment of principal of or premium, if any, and interest, if any, on the Notes which has become due solely by virtue of such acceleration) have been cured or waived and if the rescission would not conflict with any judgment or decree of any court of competent jurisdiction. No such rescission shall affect any subsequent Default or Event of Default or impair any right consequent thereto. SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal of or 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 occurring upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. SECTION 6.04. Waiver of Past Defaults. The holders of a majority in aggregate principal amount of the Notes then outstanding may, on behalf of the holders of all the Notes, waive an existing Default or Event of Default and its consequences, except a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Notes (other than the non-payment of principal of and premium, if any, and interest, if any, on the Notes which has become due solely by virtue of an acceleration which has been duly rescinded as provided above), or in respect of a covenant or provision of this Indenture which cannot be modified or amended without the consent of all holders of Notes. When a Default or Event of Default is waived, it is cured and stops continuing. No waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. SECTION 6.05. Control by Majority. The holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any 22

proceeding for 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; provided that the Trustee shall have no duty or obligation (subject to Section 7.01) to ascertain whether or not such actions of forbearances are unduly prejudicial to such holders; provided, further, that the Trustee may take any other action the Trustee deems proper that is not inconsistent with such directions. SECTION 6.06. Limitation on Suits. A holder of a Note may not pursue any remedy with respect to this Indenture or the Notes unless: (1) the holder gives to the Trustee notice of a continuing Event of Default; (2) the holders of at least 25% in principal amount of the then outstanding Notes make a request to the Trustee to pursue the remedy; (3) such holder or holders offer and, if requested, provide to the Trustee indemnity 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 and, if requested, the provision of indemnity; and (5) during such 60-day period the holders of a majority in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A holder of a Note may not use this Indenture to prejudice the rights of another holder or to obtain a preference or priority over another holder. SECTION 6.07. Rights of Holders To Receive Payment. Subject to the provisions of Article XI hereof, notwithstanding any other provision of this Indenture, the right of any holder of a Note to receive payment of principal, premium, if any, and interest, if any, on the Note, on or after the respective due dates expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, or to bring suit for the enforcement of the right to convert the Note shall not be impaired or affected without the consent of the holder of a Note. SECTION 6.08. Collection Suit by Trustee. If an Event of Default specified in Section 6.01(a), (b) or (d) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of principal and interest, if any, remaining unpaid on the Notes and interest, if any, on overdue principal and interest, if any, and such further amount as shall be sufficient to cover the costs and, to the extent lawful, 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 may 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 and the holders of Notes allowed in any judicial proceedings relative to the Company, its creditors or its property. Nothing contained herein shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any holder of a Note any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any holder thereof, or to authorize the Trustee to vote in respect of the claim of any holder in any such proceeding. 23

SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article VI, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.07, 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 Senior Debt to the extent required by Article XI; Third: to holders of Notes for amounts due and unpaid on the Notes for principal, premium, if any, and interest, if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, if any, respectively; and Fourth: to the Company. The Trustee may fix a special record date and payment date for any payment to holders of Notes made pursuant to this section. At least 15 days before any such special record date, the Trustee shall mail to holders of the Notes a notice that states the special record date, payment date and amount of such interest to be paid. 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, other than the Trustee, of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a holder pursuant to Section 6.07 or a suit by holders of more than 10% in principal amount of the then outstanding Notes. ARTICLE VII THE TRUSTEE The Trustee hereby accepts the trust imposed upon it by this Indenture and covenants and agrees to perform the same, as herein expressed. Whether or not herein expressly so provided, every provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Article VII. SECTION 7.01. Duties of the Trustee. (a) If an Event of Default known to the Trustee has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent Person would exercise or use under the circumstances in the conduct of his or her own affairs.

(d) Whether or not therein expressly so provided, every provision of this Indenture that is in any way related to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any financial liability in the performance of any of its duties or the exercise of any of its rights and powers hereunder, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk of liability is not reasonably assured to it. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 7.02. Rights of the Trustee.

The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel.

(h) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, security or other document unless requested in writing to do so by the holders of not less than a majority in aggregate principal amount of the Notes then outstanding, provided that if the Trustee determines in its discretion to make any such investigation, then it shall be entitled, upon reasonable prior notice and during normal business hours, to examine the books and records and the premises of the Company, personally or by agent or attorney, and the reasonable expenses of every such examination shall be paid by the Company or, if paid by the Trustee or any predecessor Trustee, shall be reimbursed by the Company upon demand.

SECTION 7.03. Individual Rights of the Trustee. Subject to Sections 7.10 and 7.11, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes with the same rights it would have if it were not the Trustee and may otherwise deal with the Company or an Affiliate of the Company and receive, collect, hold and retain collections from the Company with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. SECTION 7.04. Trustee's Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture 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 shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. SECTION 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each holder of a Note a notice of the Default or 26

Event of Default within 60 days after it occurs. A Default or an Event of Default shall not be considered known to the Trustee unless it is a Default or Event of Default in the payment of principal or interest when due under Section 6.01(a), (b) or (d) or the Trustee shall have received notice thereof, in accordance with this Indenture, from the Company or from the holders of a majority in principal amount of the outstanding Notes. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest, if any, on any Note, the Trustee may withhold the notice if and so long as a committee of its Trust Officers in good faith determines that withholding the notice is in the interest of the holders of the Notes. SECTION 7.06. Reports by the Trustee to Holders. Within 60 days after the reporting date stated in Section 10.10, the Trustee shall mail to holders of 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 twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with TIA Section 313 (b) (2). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to holders of Notes shall be filed, at the expense of the Company, by the Trustee with the Commission and each stock exchange or securities market, if any, on which the Notes are listed. The Company shall timely notify the Trustee when the Notes are listed or quoted on any stock exchange or securities market. SECTION 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time and the Trustee shall be entitled to reasonable compensation for its acceptance of this Indenture and its services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by or on behalf of it in addition to the compensation for its services. Such expenses may include the reasonable compensation, disbursements and expenses of the Trustee's agents, counsel and other persons not regularly in its employ. The Company shall indemnify the Trustee against any loss, liability or expense incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture and the trusts hereunder, including the costs and expenses of defending itself against or investigating any claim of liability in the premises, except as set forth in the next paragraph. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim with counsel designated by the Company, who may be outside counsel to the Company but shall in all events be reasonably satisfactory to the Trustee, and the Trustee shall cooperate in the defense. In addition, the Trustee may retain one separate counsel and, if deemed advisable by such counsel, local counsel, and the Company shall pay the reasonable fees and expenses of such separate counsel and local counsel. The indemnification herein extends to any settlement, provided that the Company will not be liable for any settlement made without its consent, provided, further, that such consent will not be unreasonably withheld. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through its own negligence or willful misconduct. The Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee to secure the Company's payment obligations in this Section 7.07, except that held in trust to pay principal and interest, if any, on Notes. Such liens and the Company's obligations under this Section 7.07 shall survive the satisfaction and discharge of this Indenture. 27

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) 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. SECTION 7.08. Replacement of the Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 7.08. The Trustee may resign at any time and be discharged from the trust hereby created by so notifying the Company. The holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor Trustee. The Company may remove the Trustee if: (1) the Trustee fails to comply with Section 7.10; (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (3) a Custodian or public officer takes charge of the Trustee or its property; or (4) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the holders of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee after written request by any holder of a Note who has been a holder for at least six months fails to comply with Section 7.10, such holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to holders of Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the retiring Trustee hereunder have been paid and subject to the lien provided for in Section 7.07. Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Company's obligations under Section 7.07 shall continue for the benefit of the retiring Trustee with respect to expenses and liabilities incurred by it prior to such replacement. Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the preceding paragraph. 28

SECTION 7.09. Successor Trustee by Merger, etc. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business (including the trust created by this Indenture) to, another corporation or national banking association, the resulting, surviving or transferee corporation or national banking association without any further act shall be the successor Trustee with the same effect as if the successor Trustee had been named as the Trustee herein. SECTION 7.10. Eligibility, Disqualification. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310 (a) (1). The Trustee shall always have a combined capital and surplus as stated in Section 10.10. The Trustee is subject to TIA Section 310(b) regarding the disqualification of a trustee upon acquiring a conflicting interest. SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311 (a), excluding any creditor relationship set forth in TIA Section 311 (b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. ARTICLE VIII SATISFACTION AND DISCHARGE OF INDENTURE SECTION 8.01. Discharge of Indenture. When (a) the Company delivers to the Trustee for cancellation all Notes theretofore authenticated (other than any other Notes which have been destroyed, lost or stolen and in lieu of or in substitution for which other Notes have been authenticated and delivered) and not theretofore canceled, or (b) all the Notes not theretofore canceled or delivered to the Trustee for cancellation have become due and payable or by their terms will become due and payable within one year, and the Company deposits with the Trustee, in trust, amounts sufficient to pay at maturity of all of the Notes (other than any Notes which have been mutilated, destroyed, lost or stolen and in lieu of or in substitution for which other Notes have been authenticated and delivered) not theretofore canceled or delivered to the Trustee for cancellation, including principal and premium, if any, and interest, if any, due or to become due to such date of maturity, and if the Company also pays, or causes to be paid, all other sums payable hereunder by the Company, then this Indenture shall cease to be of further effect (except as to (i) rights of registration of transfer, substitution, replacement and exchange and conversion of Notes, (ii) rights hereunder of holders of Notes to receive payments of principal of and premium, if any, and interest, if any, on the Notes, (iii) the obligations under Sections 2.03 and 8.05 hereof and (iv) the rights, obligations and immunities of the Trustee hereunder), and the Trustee, on demand of the Company accompanied by an Officers' Certificate and an Opinion of Counsel as required by Section 10.04 and at the Company's cost and expense, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture; the Company, however, hereby agrees to reimburse the Trustee for any costs or expenses thereafter reasonably and properly incurred by the Trustee and to compensate the Trustee for any services thereafter reasonably and properly rendered by the Trustee in connection with this Indenture or the Notes. SECTION 8.02. Deposited Monies to be Held in Trust by Trustee. Subject to Section 8.04, all monies deposited with the Trustee pursuant to Section 8.01 shall be held in trust and applied by it to the payment, notwithstanding the provisions of Article XI, either directly or through the Paying Agent, to the holders of the particular Notes for the payment of which such monies have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest, if any, and premium, if any. SECTION 8.03. Paying Agent to Repay Monies Held. Upon the satisfaction and discharge of this Indenture, all monies then held by any Paying Agent (other than the Trustee) shall, upon the Company's demand, be repaid to it or paid to the Trustee, and thereupon such Paying Agent shall be released from all further liability with respect to such monies. 29

SECTION 8.04. Return of Unclaimed Monies. Subject to the requirements of applicable law, any monies deposited with or paid to the Trustee for payment of the principal of, premium, if any, or interest, if any, on Notes and not applied but remaining unclaimed by the holders thereof for two years after the date upon which the principal of, premium, if any, or interest on such Notes, as the case may be, have become due and payable, shall be repaid to the Company by the Trustee on demand; provided, however, that the Company, or the Trustee at the request of the Company, shall have first caused notice of such payment to the Company to be mailed to each holder of a Note entitled thereto no less than 30 days prior to such payment and all liability of the Trustee shall thereupon cease with respect to such monies; and the holder of any of the Notes shall thereafter look only to the Company for any payment which such holder may be entitled to collect unless an applicable abandoned property law designates another Person. SECTION 8.05. Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with Section 8.02 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.01 until such time as the Trustee or the Paying Agent is permitted to apply all such money in accordance with Section 8.02; provided, however, that if the Company makes any payment of interest on or principal of any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the holders thereof to receive such payment from the money held by the Trustee or Paying Agent. ARTICLE IX AMENDMENTS SECTION 9.01. Without the Consent of Holders. The Company and the Trustee may amend this Indenture or the Notes without notice to or the consent of any holder of a Note for the purposes of: (a) curing any ambiguity or correcting or supplementing any defective or inconsistent provision contained in this Indenture or making any other changes in the provisions of this Indenture which the Company and the Trustee may deem necessary or desirable provided such amendment does not materially and adversely affect the legal rights under the Indenture of the holders of Notes; (b) providing for uncertificated Notes in addition to or in place of certificated Notes; (c) evidencing the succession of another Person to the Company and providing for the assumption by such successor of the covenants and obligations of the Company thereunder and in the Notes as permitted by Section 5.01; (d) providing for conversion rights and/or repurchase rights of holders of Notes in the event of consolidation, merger or sale of all or substantially all of the assets of the Company as required to comply with Sections 5.01 and/or 12.06; (e) increasing the Conversion Rate; (f) making any changes that would provide the holders of the Notes with any additional rights or benefits or that does not adversely affect the legal rights under this Indenture of any such holder; or (g) complying with the requirements of the Commission in order to effect or maintain the qualification of the Indenture under the TIA. 30

Subject to Sections 6.04 and 6.07, the holders of a majority in principal amount of the Notes then outstanding may also waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent of each holder of a Note affected, an amendment or waiver under this Section may not (with respect to any Notes held by a non-consenting holder): (a) reduce the principal amount of Notes whose holders must consent to an amendment, supplement or waiver; (b) reduce the principal of, or change the fixed maturity of any Note; (c) reduce the rate of, or change the time for payment of, interest, including defaulted interest, if any, on any Note; (d) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest 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 Notes then outstanding and a waiver of the payment default that resulted from such acceleration); (e) make the principal of, or premium, if any, or interest on any Note payable in money other than as provided for herein and in the Notes; (f) make any change in the provisions of this Indenture relating to waivers of past Defaults or Events of Default or the rights of holders of Notes to receive payments of principal of, premium, if any, or interest or the Notes; (g) except as permitted herein (including Section 9.01(a)), reduce the Conversion Rate or modify the provisions contained herein relating to conversion of the Notes in a manner adverse to the holders thereof; or (h) make any change to the abilities of holders of Notes to enforce their rights hereunder or the provisions of clauses (a) through (g) of this Section 9.02. In order to amend any provisions of Article XI, holders of at least 75% in aggregate principal amount of Notes then outstanding must consent to such amendment if such amendment would adversely affect the rights of holders of Notes. To secure a consent of the holders of Notes under this Section, it shall not be necessary for such holders to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment or waiver under this Article IX becomes effective, the Company shall mail to holders of Notes a notice briefly describing the amendment or waiver. 31

SECTION 9.03. Compliance with the Trust Indenture Act. Every amendment to this Indenture or the Notes shall be set forth in a supplemental indenture that complies with the TIA as then in effect. SECTION 9.04. Revocation and Effect of Consents. Until an amendment or waiver becomes effective, a consent to it by a holder of a Note is a continuing consent by the holder 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 or subsequent holder may revoke the consent as to his or her Note or portion of a Note if the Trustee receives the notice of revocation before the date on which the Trustee receives an Officers' Certificate certifying that the holders of the requisite principal amount of Notes have consented to the amendment or waiver. The Company may, but shall not be obligated to, fix a record date for the purpose of determining the holders of Notes entitled to consent to any amendment or waiver. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were holders of Notes at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from holders of the principal amount of Notes required hereunder for such amendment or waiver to be effective shall have also been given and not revoked within such 90-day period. After an amendment or waiver becomes effective it shall bind every holder of a Note, unless it is of the type described in clauses (a) through (h) of Section 9.02. In such cases, the amendment or waiver shall bind each holder of a Note who has consented to it and every subsequent holder of a Note or portion of a Note that evidences the same debt as the consenting holder's Note. SECTION 9.05. Notation on or Exchange of Notes. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article IX may, and shall if required by the Trustee, bear a notation in the form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion of the Company and the Trustee, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for outstanding Notes without charge to the holders of the Notes, except as specified in Section 2.06. SECTION 9.06. Trustee Protected. The Trustee shall sign any amendment or supplemental indenture authorized pursuant to this Article IX if such amendment or supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing such amendment or supplemental indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officers' Certificate and an Opinion of Counsel as conclusive evidence that such amendment or supplemental indenture is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding upon the Company in accordance with its terms. ARTICLE X GENERAL PROVISIONS SECTION 10.01. Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA Section 318(c), such duties imposed by such section of the TIA shall control. If any provision of this Indenture expressly modifies or excludes any provision 32

of the TIA that may be so modified or excluded, the Indenture provision so modifying or excluding such provision of the TIA shall be deemed to apply. SECTION 10.02. Notices. Any notice or communication by the Company or the Trustee to the other is duly given if in writing and delivered in person or mailed by first-class mail, with postage prepaid (registered or certified, return receipt requested), or sent by facsimile or overnight air couriers guaranteeing next day delivery, to the other's address as stated in Section 10.10. The Company or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications. All notices and communications (other than those sent to holders of Notes) shall be deemed to have been duly given at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; when transmission is confirmed, if transmitted by facsimile; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery. Notwithstanding the foregoing, all notices to the Trustee shall be effective only upon receipt by a Trust Officer. Any notice or communication to a holder of a Note shall be mailed by first-class mail, with postage prepaid, to his or her address shown on the Register kept by the Registrar. Failure to mail a notice or communication to a holder or any defect in it shall not affect its sufficiency with respect to other holders. If a notice or communication is sent in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it. If the Company sends a notice or communication to holders of Notes, it shall send a copy to the Trustee and each Agent at the same time. All notices or communications shall be in writing. SECTION 10.03. Communication by Holders With Other Holders. Holders may communicate pursuant to TIA Section 312(b) with other holders with respect to their rights under this Indenture or the Notes. The Company, the Trustee, the Registrar and anyone else shall have the protection of TIA Section 312(c). SECTION 10.04. Certificate and Opinion as to Conditions Precedent. Upon any request or application by the Company to the Trustee to take any action under this Indenture, the Company shall furnish to the Trustee: (1) an Officers' Certificate in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 10.05) stating that, in the opinion of such person, all conditions precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been complied with; and (2) an Opinion of Counsel in form and substance reasonably satisfactory to the Trustee (which shall include the statements set forth in Section 10.05) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been complied with. SECTION 10.05. Statements Required in Certificate or Opinion. Each certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture (other than a certificate provided pursuant to TIA Section 314(a) (4)) shall include: 33

(1) a statement that the person making such certificate or opinion has read such covenant or condition; (2) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (3) a statement that, in the opinion of such person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and (4) a statement as to whether or not, in the opinion of such person, such condition or covenant has been complied with. Any Officers' Certificate may be based, insofar as it relates to legal matters, upon an Opinion of Counsel, unless such Officer knows that the opinion with respect to the matters upon which his or her certificate may be based as aforesaid is erroneous. Any Opinion of Counsel may be based, insofar as it relates to factual matters, upon certificates, statements or opinions of, or representations by, an officer or officers of the Company, or other Persons or firms deemed appropriate by such counsel, unless such counsel knows that the certificates, statements or opinions or representations with respect to the matters upon which his or her opinion may be based as aforesaid are erroneous. Any Officers' Certificate, statement or Opinion of Counsel may be based, insofar as it relates to accounting matters, upon a certificate or opinion of or representation by an accountant (who may be an employee of the Company), or firm of accountants, unless such Officer or counsel, as the case may be, knows that the certificate or opinion or representation with respect to the accounting matters upon which his or her certificate, statement or opinion may be based as aforesaid is erroneous. SECTION 10.06. Rules by Trustee and Agents. The Trustee may make reasonable rules for action by, or a meeting of, holders of Notes. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions. SECTION 10.07. Legal Holidays. A "Legal Holiday" is a Saturday, a Sunday or a day on which banking institutions in the City of New York, the city in which the Corporate Trust Office of the Trustee is located or the City of New York, New York are not required to be open, and a "Business Day" is any day that is not a Legal Holiday. If a payment date is a Legal Holiday at a place of payment, payment may be made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period. If any date specified in this Indenture, is a Legal Holiday, then such date shall be the next succeeding Business Day. SECTION 10.08. No Recourse Against Others. No director, officer, employee or stockholder, as such, of the Company from time to time shall have any liability for any obligations of the Company under the Notes or this 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. This waiver and release are part of the consideration for the Notes. Each of such directors, officers, employees and stockholders is a third party beneficiary of this Section 10.08. SECTION 10.09. Counterparts. This Indenture may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 34

The Trustee shall always have, or shall be a Subsidiary of a bank or bank holding company which has, a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Company's address is: Amkor Technology, Inc. 1900 South Price Road Chandler, AZ 85248 Attention: Chief Financial Officer Facsimile: (480) 821-2616 Telephone: (480) 821-5000 The Trustee's address is: U.S. Bank National Association One Federal Street, 3rd Floor Boston, MA 02110 Attention: Corporate Trust Services (Amkor Technology, Inc. 2.50% Convertible Senior Subordinated Notes due 2011) Facsimile: (617) 603-6665 Telephone: (617) 603-6562 SECTION 10.11. Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE AND THE NOTES BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. SECTION 10.12. No Adverse Interpretation of Other Agreements. This Indenture may not be used to interpret another indenture, loan or debt agreement of the Company or a Subsidiary of the Company.

ARTICLE XI SUBORDINATION SECTION 11.01. Agreement to Subordinate. The Company agrees, and each holder of Notes by accepting a Note agrees, that the indebtedness evidenced by the Note is subordinated in right of payment, to the extent and in the manner provided in this Article XI, to the prior payment in full in cash of all Senior Debt (whether outstanding on the Issue Date or thereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt. The Company agrees, and each holder of Notes by accepting a Note agrees, that the indebtedness evidenced by the Note is equal in right of payment to the Existing Pari Passu Indebtedness. The Notes shall be "Designated Senior Debt" for purposes of the indentures governing the Company's Convertible Subordinated Notes. SECTION 11.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of creditors or any marshaling of the Company's assets and liabilities: (1) holders of Senior Debt shall be entitled to receive payment in full of all Obligations due in respect of such Senior Debt (including interest, expense reimbursements and indemnities after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not such claims are allowed, allowable or enforceable in such proceeding and even if disallowed therein) before the holders of the Notes shall be entitled to receive any payment with respect to the Notes (except that holders of the Notes may receive and retain (A) Permitted Junior Securities and (B) payments and other distributions made from any trust created pursuant to Section 8.02 hereof); and (2) until all Obligations with respect to Senior Debt (as provided in clause (1) above) are paid in full, any distribution to which holders of Notes would be entitled but for this Article XI shall be made to holders of Senior Debt (except that holders of the Notes may receive and retain (A) Permitted Junior Securities and (B) payments and other distributions made from any trust created pursuant to Section 8.02 hereof), as their interests may appear. SECTION 11.03. Default on Designated Senior Debt. The Company may not make any payment or distribution to the Trustee or any holder of Notes in respect of Obligations with respect to the Notes and may not acquire from the Trustee or any holder of Notes for cash or property (other than (A) Permitted Junior Securities and (B) payments and other distributions made from any trust created pursuant to Section 8.02 hereof) until all principal and other Obligations with respect to the Senior Debt have been paid in full if: (i) a default in the payment of any principal or other Obligations in respect of Senior Debt occurs and is continuing beyond any applicable grace period in the agreement, indenture or other document governing such Senior Debt; or (ii) a default, other than a payment default, on Designated Senior Debt occurs and is continuing that then permits holders of such Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of the default (a "Payment Blockage Notice") from a Person who may give it pursuant to Section 11.11 hereof. If the Trustee receives any Payment Blockage Notice pursuant to Section 11.03 (ii) hereof, no subsequent Payment Blockage Notice shall be effective for purposes of such Section unless and until (A) at least 360 days shall have elapsed since the effectiveness of the immediately prior 36

Payment Blockage Notice and (B) all scheduled payments of principal, premium, if any, and interest on the Notes that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a subsequent Payment Blockage unless such default shall have been cured or waived for a period of not less than 180 days. The Company may and shall resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: (1) the date upon which the default is cured or waived, or (2) in the case of a nonpayment default referred to in Section 11.03(ii) hereof, the earlier of the date on which such nonpayment default is cured or waived or 179 days after notice is received, unless the maturity of such Designated Senior Debt has been accelerated, if this Article XI otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. SECTION 11.04. Acceleration of Notes. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt (or their Representative) of the acceleration. SECTION 11.05. When Distribution Must Be Paid Over. In the event that the Trustee or any holder of Notes receives any payment of any Obligations with respect to the Notes (other than (A) in Permitted Junior Securities and (B) payments and other distributions made from any trust created pursuant to Section 8.02 hereof) at a time when such payment is prohibited by the provisions of this Article XI and the Trustee or such holder of Notes, as applicable, has actual knowledge that such payment is prohibited by Section 11.03 hereof, then such payment shall be held by the Trustee or holder of Notes in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to holders of Senior Debt as their interests may appear or their Representative under the indenture or other agreement (if any) pursuant to which Senior Debt may have been issued, as their respective interests may appear, for application to the payment of all Obligations with respect to Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt. With respect to the holders of Senior Debt, the Trustee undertakes to perform only such obligations on the part of the Trustee as are specifically set forth in this Article XI, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and shall not be liable to any such holders if the Trustee shall pay over or distribute to or on behalf of holders of Notes or the Company or any other Person money or assets to which any holders of Senior Debt shall be entitled by virtue of this Article XI, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. SECTION 11.06. Notice by Company. The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Notes or the purchase of any Notes by the Company to violate this Article XI, but failure to give such notice shall not affect the subordination of the Notes to the Senior Debt as provided in this Article XI. 37

SECTION 11.07. Subrogation. After all Senior Debt is paid in full and until the Notes are paid in full, holders of Notes shall be subrogated (equally and ratably with all other indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that distributions otherwise payable to the holders of Notes have been applied to the payment of Senior Debt. A distribution made under this Article XI to holders of Senior Debt that otherwise would have been made to holders of Notes is not, as between the Company and holders of Notes, a payment by the Company on the Notes. SECTION 11.08. Relative Rights. This Article XI defines the relative rights of holders of Notes and holders of Senior Debt. Nothing in this Indenture shall: (1) impair, as between the Company and holders of Notes, the obligation of the Company, which is absolute and unconditional, to pay principal of and interest on the Notes in accordance with their terms; (2) affect the relative rights of holders of Notes and creditors of the Company, other than their rights in relation to holders of Senior Debt; or (3) prevent the Trustee or any holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to holders of Notes. If the Company fails because of this Article XI to pay principal of or interest on a Note on the due date, the failure is still a Default or Event of Default. SECTION 11.09. Subordination May Not Be Impaired by Company. No right of any holder of Senior Debt to enforce the subordination of the indebtedness evidenced by the Notes shall be impaired by any act or failure to act by the Company or any holder of Notes or by the failure of the Company or any such holder to comply with this Indenture. SECTION 11.10. Distribution or Notice to Representative. Whenever a distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their Representative. Upon any payment or distribution of assets of the Company referred to in this Article XI, the Trustee and the holders of Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XI. SECTION 11.11. Rights of Trustee and Paying Agent. Notwithstanding the provisions of this Article XI or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless the Trustee shall have received at least two Business Days prior to the date of such payment or distribution written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article XI. Only the Company or a Representative may give the notice. 38

Nothing in this Article XI shall impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof. The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. SECTION 11.12. Authorization to Effect Subordination. Each holder of a Note by the holder's acceptance thereof authorizes and directs the Trustee on the holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article XI, and appoints the Trustee to act as the holder's attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, the holders of any Senior Debt or their Representatives are hereby authorized to file an appropriate claim for and on behalf of the holders of the Notes. SECTION 11.13. Amendments. The provisions of this Article XI shall not be amended or modified without the written consent of the holders of all Senior Debt. SECTION 11.14. Senior Debt Entitled to Rely. The holders of Senior Debt shall have the right to rely upon this Article XI, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. ARTICLE XII CONVERSION OF CONVERTIBLE SENIOR SUBORDINATED NOTES SECTION 12.01. Right to Convert. Subject to and upon compliance with the provisions of this Indenture, each holder of Notes shall have the right, at such holder's option, at any time on or before the close of business on the last trading day prior to the Maturity Date (except that, with respect to any Note or portion thereof subject to a duly completed election for repurchase, such right shall terminate on or before the close of business on the Designated Event Offer Termination Date (unless the Company defaults in the payment due upon repurchase)) to convert the principal amount of any Note held by such holder, or any portion of such principal amount which is $1,000 or an integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock (as such shares shall then be constituted) based on the Conversion Rate in effect at such time, by surrender of the Note so to be converted in whole or in part in the manner provided in Section 12.02. A holder of Notes is not entitled to any rights of a holder of Common Stock until such holder of Notes has converted his or her Notes to Common Stock, and only to the extent such Notes are deemed to have been converted to Common Stock under this Article XII. SECTION 12.02. Exercise of Conversion Privilege; Issuance of Common Stock on Conversion; No Adjustment for Interest or Dividends. To exercise, in whole or in part, the conversion privilege with respect to any Note, the holder of such Note shall surrender such Note, duly endorsed, at an office or agency maintained by the Company pursuant to Section 4.04, accompanied by the funds, if any, required by the last paragraph of this Section 12.02, and shall give written notice of conversion in the form provided on the Notes (or such other notice which is acceptable to the Company) to the office or agency that the holder of Notes elects to convert such Note or such portion thereof specified in said notice. Such notice shall also state the name or names (with address or addresses) in which the certificate or certificates for shares of Common Stock which are issuable on such conversion shall be issued, and shall be accompanied by transfer taxes, if required pursuant to Section 12.07. Each such Note surrendered for conversion shall, unless the shares issuable on conversion are to be issued in the same name as the 39

registration of such Note, be duly endorsed by, or be accompanied by instruments of transfer in form satisfactory to the Company duly executed by, the holder of Notes or his or her duly authorized attorney. As promptly as practicable after satisfaction of the requirements for conversion set forth above, the Company shall issue and shall deliver to such holder at the office or agency maintained by the Company for such purpose pursuant to Section 4.04, a certificate or certificates for, or effect a book-entry transfer through the Depositary with respect to, the number of full shares of Common Stock issuable upon the conversion of such Note or portion thereof in accordance with the provisions of this Article XII and a check or cash in respect of any fractional interest in respect of a share of Common Stock arising upon such conversion, as provided in Section 12.03 (which payment, if any, shall be paid no later than five Business Days after satisfaction of the requirements for conversion set forth above). Certificates representing shares of Common Stock will not be issued or delivered unless all taxes and duties, if any, payable by the holder have been paid. In case any Note of a denomination of an integral multiple greater than $1,000 is surrendered for partial conversion, and subject to Section 2.02, the Company shall execute, and the Trustee shall authenticate and deliver to the holder of the Note so surrendered, without charge to him or her, a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered Note. Each conversion shall be deemed to have been effected as to any such Note (or portion thereof) on the date on which the requirements set forth above in this Section 12.02 have been satisfied as to such Note (or portion thereof), and the Person in whose name any certificate or certificates for shares of Common Stock are issuable upon such conversion shall be deemed to have become on said date the holder of record of the shares represented thereby; provided, however, that any such surrender on any date when the Company's stock transfer books are closed shall constitute the Person in whose name the certificates are to be issued as the record holder thereof for all purposes on the next succeeding day on which such stock transfer books are open, but such conversion shall be at the Conversion Rate in effect on the date upon which such Note is surrendered. Any Note or portion thereof surrendered for conversion during the period from the close of business on the Regular Record Date for any interest payment through the close of business on the last trading day immediately preceding such Interest Payment Date shall be accompanied by payment, in funds acceptable to the Company, of an amount equal to the interest, otherwise payable on such Interest Payment Date on the principal amount being converted; provided however, that no such payment need be made if there exists at the time of conversion a default in the payment of interest on the Notes; and provided, further, that no such payment need be made if the Notes are surrendered for conversion on or after the final Regular Record Date. An amount equal to such payment shall be paid by the Company on such Interest Payment Date to the holder of such Note at the close of business on such Regular Record Date; provided however, that if the Company defaults in the payment of interest, if applicable, on such Interest Payment Date, such amount shall be paid to the Person who made such required payment. Except as provided above in this Section 12.02, no cash payment of interest shall be made and no adjustment shall be made for interest accrued, if any, on any Note converted or for dividends on any shares issued upon the conversion of such Note as provided in this Article XII. SECTION 12.03. Cash Payments in Lieu of Fractional Shares. No fractional shares of Common Stock or scrip representing fractional shares shall be issued upon conversion of Notes. If more than one Note shall be surrendered for conversion at one time by the same holder, the number of full shares which shall be issuable upon conversion shall be computed on the basis of the aggregate principal amount of the Notes (or specified portions thereof to the extent permitted hereby) so surrendered for conversion. If any fractional share of stock otherwise would be issuable upon the conversion of any Note or Notes, the Company shall make an adjustment therefore in cash based upon the Current Market Price 40

(as defined in Section 12.05(g)) of the Common Stock on the last trading day prior to the date of conversion. SECTION 12.04. Conversion Rate. The Conversion Rate shall be as specified in the form of Note attached as Exhibit A hereto, subject to adjustment as provided in this Article XII. SECTION 12.05. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows: (a) If the Company shall hereafter pay a dividend or make a distribution to all holders of the outstanding Common Stock in shares of Common Stock, the Conversion Rate in effect at the opening of business on the date following the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be increased by multiplying the Conversion Rate in effect at the close of business on such Record Date by a fraction of which the numerator shall be the total number of shares that would be outstanding immediately following such dividend or other distribution and the denominator shall be the number of shares of Common Stock outstanding at the close of business on the Record Date fixed for such determination, such increase to become effective immediately after the opening of business on the day following the Record Date. If any dividend or distribution of the type described in this Section 12.05(a) is declared but not so paid or made, the Conversion Rate shall again be adjusted to the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. (b) If the outstanding shares of Common Stock shall be subdivided into a greater number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such subdivision becomes effective shall be proportionately increased, and, conversely, if the outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Conversion Rate in effect at the opening of business on the day following the day upon which such combination becomes effective shall be proportionately reduced, such increase or reduction, as the case may be, to become effective immediately after the opening of business on the day following the day upon which such subdivision or combination becomes effective. (c) If the Company shall issue rights or warrants to all or substantially all holders of its outstanding shares of Common Stock entitling them to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) for a period expiring 45 days or less from the date of issuance of such rights or warrants at a price per share (or having a conversion price per share) less than the Current Market Price on the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants, the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect at the close of business on such Record Date by a fraction of which the numerator shall be the sum of the number of shares of Common Stock outstanding at the close of business on the Record Date plus the total number of additional shares of Common Stock so offered for subscription or purchase (or into which the convertible securities so offered are convertible) and of which the denominator shall be the sum of the number of shares of Common Stock outstanding at the close of business on the Record Date plus the number of shares equal to the aggregate price payable to exercise such rights or warrants (or the aggregate conversion price of the convertible securities so offered for subscription or purchase, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock pursuant to the terms of such convertible securities) divided by the Current Market Price as of the business day immediately preceding the announcement of the issuance of such rights. Such adjustment shall become effective immediately after the opening of business on the day following the Record Date fixed for determination of stockholders entitled to receive such rights or warrants. To the extent that shares of Common Stock (or securities convertible into Common Stock) are not delivered 41

pursuant to such rights or warrants, upon the expiration or termination of such rights or warrants the Conversion Rate shall be readjusted to be the Conversion Rate which would then be in effect had the adjustments made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. If such rights or warrants are not so issued, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such Record Date fixed for the determination of stockholders entitled to receive such rights or warrants had not been fixed. In determining whether any rights or warrants entitle the holders to subscribe for or purchase shares of Common Stock at less than such Current Market Price, and in determining the aggregate offering price of such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants, with the value of such consideration, if other than cash, to be determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors. (d) If the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock shares of any class of capital stock of the Company (other than any dividends or distributions to which Section 12.05(a) applies) or evidences of its indebtedness, cash or other assets (including securities, but excluding (i) any rights or warrants of a type referred to in Section 12.05(c) and (ii) dividends and distributions paid exclusively in cash pursuant to Section 12.05(e)) (the foregoing hereinafter in this Section 12.05(d) called the "Distributed Securities"), then (unless the Company distributes such Distributed Securities for distribution to the holders of Notes on such dividend or distribution date (as if each Holder had converted such Note into Common Stock immediately prior to the Record Date with respect to such distribution)), in each such case, the Conversion Rate shall be adjusted so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the Record Date with respect to such distribution by a fraction of which the numerator shall be the Current Market Price on such date and the denominator shall be such Current Market Price less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) on such date of the portion of the Distributed Securities applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on such Record Date), such increase to become effective immediately prior to the opening of business on the day following the Record Date; provided, however, that in the event the then fair market value (as so determined) of the portion of the Distributed Securities applicable to one share of Common Stock is equal to or greater than the Current Market Price on the Record Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Notes shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of Distributed Securities such holder would have received had such holder converted such Note (or portion thereof) immediately prior to such Record Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair market value of any distribution for purposes of this Section 12.05(d) by reference to the actual or when issued trading market for any securities comprising all or part of such distribution, in doing so the Board of Directors shall, to the extent possible, consider the prices in such market over the same period used in computing the Current Market Price pursuant to Section 12.05(g). Notwithstanding any other provision of this Section 12.05(d) to the contrary, rights, warrants, evidences of indebtedness, other securities, cash or other assets (including, without limitation, any rights distributed pursuant to any stockholder rights plan) shall be deemed not to have been distributed for purposes of this Section 12.05(d) if the Company makes proper provision so that each holder of Notes who converts a Note (or any portion thereof) after the Record Date fixed for determination of stockholders entitled to receive such distribution shall be entitled to receive upon such conversion, in addition to the shares of Common Stock issuable upon such conversion, the amount and 42

kind of such distributions that such holder would have been entitled to receive if such holder had, immediately prior to such determination date, converted such Note into Common Stock. Notwithstanding the foregoing, if the securities distributed by the Company to all holders of its Common Stock consist of Capital Stock of, or similar equity interests in, a Subsidiary or other business unit of the Company (the "Spinoff Securities"), the Conversion Rate shall be adjusted, unless the Company makes an equivalent distribution to the holders of the Notes, so that the same shall be equal to the rate determined by multiplying the Conversion Rate in effect at the close of business on the Record Date fixed for the determination of stockholders entitled to receive such distribution by a fraction, the numerator of which shall be the sum of (A) the average Closing Price of one share of Common Stock over the 10 consecutive trading days (the "Spinoff Valuation Period") commencing on and including the fifth trading day after the date on which ex-dividend trading commences for such distribution on the Nasdaq National Market or such other U.S. national or regional exchange or market on which the Common Stock is then listed or quoted, and (B) the average Closing Price over the Spinoff Valuation Period of the Spinoff Securities; provided, that if shares of such Capital Stock or equity interests are not so listed or quoted, the fair market value as determined in good faith by the Company's Board of Directors, and the denominator of which shall be the average Closing Price of one share of Common Stock over the Spinoff Valuation Period, such adjustment to become effective immediately prior to the opening of business on the fifteenth trading day after the date on which ex-dividend trading commences; provided, however, that the Company may in lieu of the foregoing adjustment elect to make adequate provision so that each Holder of Securities shall have the right to receive upon conversion thereof the amount of such Spinoff Securities that such Holder of Securities would have received if such Securities had been converted on the record date with respect to such distribution. For purposes of this Section 12.05(d) and Sections 12.05(a) and (c), any dividend or distribution to which this Section 12.05(d) is applicable that also includes shares of Common Stock, or rights or warrants to subscribe for or purchase shares of Common Stock to which Section 12.05(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of the evidences of indebtedness, assets, shares of capital stock, rights or warrants other than such shares of Common Stock or rights or warrants to which Section 12.05(c) applies (and any Conversion Rate adjustments required by this Section 12.05(d) with respect to such dividend or distribution shall then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock or such rights or warrants (and any further Conversion Rate adjustments required by Sections 12.05(a) and (c) with respect to such dividend or distribution shall then be made, except that (A) the Record Date of such dividend or distribution shall be substituted as "the Record Date fixed for the determination of stockholders entitled to receive such dividend or other distribution", "Record Date fixed for such determination" and "Record Date" within the meaning of Section 12.05(a) and as "the Record Date fixed for the determination of stockholders entitled to receive such rights or warrants", "the Record Date fixed for the determination of the stockholders entitled to receive such rights or warrants" and "such Record Date" within the meaning of Section 12.05(c) and (B) any shares of Common Stock included in such dividend or distribution shall not be deemed "outstanding at the close of business on the date fixed for such determination" within the meaning of Section 12.05(a)). (e) If the Company shall make any dividend or other distribution (a "Triggering Distribution") consisting exclusively of cash to all holders of its Common Stock (excluding any cash that is distributed upon a merger or consolidation to which Section 12.06 applies or as part of a distribution referred to in Section 12.05(d)) the Conversion Rate shall be adjusted so that the same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior to the close of business on the record date for such Triggering Distribution (a "Distribution Determination Date") by a fraction the numerator of which shall be the Current Market Price per share of Common Stock on such Distribution Determination Date and the denominator of which shall be the Current Market Price per share of 43

Common Stock on such Distribution Determination Date less the amount of such cash dividend or distribution applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding at the close of business on the Distribution Determination Date); provided, however, that if the portion of the cash so distributed applicable to one share of Common Stock is equal to or greater than the Current Market Price of the Common Stock on the Distribution Determination Date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of Notes shall have the right to receive upon conversion of a Note (or any portion thereof) the amount of cash such holder would have received had such holder converted such Note (or portion thereof) immediately prior to such Distribution Determination Date. If such dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such dividend or distribution had not been declared. (f) If a tender or exchange offer made by the Company or any of its subsidiaries for all or any portion of the Common Stock expires and such tender or exchange offer (as amended upon the expiration thereof) requires the payment to stockholders (based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of Purchased Shares (as defined below)) of an aggregate consideration having a fair market value (as determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors) that exceeds the Current Market Price per share of Common Stock on the trading day next succeeding the last date (the "Expiration Date") tenders or exchanges could have been made pursuant to such tender or exchange offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is hereinafter called the "Expiration Time"), then the Conversion Rate shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Rate in effect immediately prior to close of business on the Expiration Date by a fraction of which the numerator shall be the sum of (A) the fair market value of the aggregate consideration (the fair market value as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers' Certificate delivered to the Trustee) payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender or exchange offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares deemed so accepted, up to any such maximum, being referred to as the "Purchased Shares") and (B) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury of the Company) at the Expiration Time and the Closing Price per share of Common Stock on the trading day next succeeding the Expiration Date and the denominator of which shall be the product of the number of shares of Common Stock outstanding (including Purchased Shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied by the Closing Price per share of the Common Stock on the trading day next succeeding the Expiration Date, such adjustment (if any) to become effective immediately prior to the opening of business on the day following the Expiration Date. If the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently prevented by applicable law from effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again be adjusted to be the Conversion Rate which would then be in effect if such tender offer had not been made. If the application of this Section 12.05(f) to any tender offer would result in a decrease in the Conversion Rate, no adjustment shall be made for such tender offer under this Section 12.05(f). (g) For purposes of this Section 12.05, the following terms shall have the meaning indicated: (1) "Closing Price" with respect to any securities on any day means the closing price on such day or, if no such sale takes place on such day, the average of the reported high and low prices on such day, in each case on the Nasdaq National Market or New York Stock Exchange, as applicable, or, if such security is not listed or admitted to trading on such national 44

market or exchange, on the principal national securities exchange or quotation system on which such security is quoted or listed or admitted to trading, or, if not quoted or listed or admitted to trading on any national securities exchange or quotation system, the average of the high and low prices of such security on the over-the-counter market on the day in question as reported by the National Quotation Bureau Incorporated, or a similar generally accepted reporting service, or, if not so available, in such manner as furnished by any New York Stock Exchange member firm selected from time to time by the Board of Directors for that purpose, or a price determined in good faith by the Board of Directors, whose determination shall be conclusive and described in a resolution of the Board of Directors. (2) "Current Market Price" means the average of the daily Closing Price per share of Common Stock for the 10 consecutive trading days immediately prior to the date in question; provided, however, that (1) if the "ex" date (as hereinafter defined) for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Sections 12.05(a), (b), (c), (d), (e) or (f) occurs during such 10 consecutive trading days, the Closing Price for each trading day prior to the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the same fraction by which the Conversion Rate is so required to be adjusted as a result of such other event, (2) if the "ex" date for any event (other than the issuance or distribution requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.05(a), (b), (c), (d), (e) or (f) occurs on or after the "ex" date for the issuance or distribution requiring such computation and prior to the day in question, the Closing Price for each trading day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event, and (3) if the "ex" date for the issuance or distribution requiring such computation is prior to the day in question, after taking into account any adjustment required pursuant to clause (1) or (2) of this proviso, the Closing Price for each trading day on or after such "ex" date shall be adjusted by adding thereto the amount of any cash and the fair market value (as determined by the Board of Directors in a manner consistent with any determination of such value for purposes of Sections 12.05(d) or (f), whose determination shall be conclusive and described in a resolution of the Board of Directors) of the evidences of indebtedness, shares of capital stock or assets being distributed applicable to one share of Common Stock as of the close of business on the day before such "ex" date. For purposes of any computation under Section 12.05(f), the Current Market Price on any date shall be deemed to be the average of the daily Closing Prices per share of Common Stock for such day and the next two succeeding trading days; provided, however, that if the "ex" date for any event (other than the tender offer requiring such computation) that requires an adjustment to the Conversion Rate pursuant to Section 12.05(a), (b), (c), (d), (e) or (f) occurs on or after the Expiration Time for the tender or exchange offer requiring such computation and prior to the day in question, the Closing Price for each trading day on and after the "ex" date for such other event shall be adjusted by multiplying such Closing Price by the reciprocal of the fraction by which the Conversion Rate is so required to be adjusted as a result of such other event. For purposes of this paragraph, the term "ex" date, (1) when used with respect to any issuance or distribution, means the first date on which the Common Stock trades regular way on the relevant exchange or in the relevant market from which the Closing Price was obtained without the right to receive such issuance or distribution, (2) when used with respect to any subdivision or combination of shares of Common Stock, means the first date on which the Common Stock trades regular way on such exchange or in such market after the time at which such subdivision or combination becomes effective, and (3) when used with respect to any tender or exchange offer means the first date on which the Common Stock trades regular way on such exchange or in such market after the Expiration Time of such offer. Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are called for pursuant to this Section 12.05, such 45

adjustments shall be made to the Current Market Price as may be necessary or appropriate to effectuate the intent of this Section 12.05 and to avoid unjust or inequitable results as determined in good faith by the Board of Directors. (3) "fair market value" shall mean the amount which a willing buyer would pay a willing seller in an arm's length transaction. (4) "Record Date" shall mean, with respect to any dividend, distribution or other transaction or event in which the holders of Common Stock have the right to receive any cash, securities or other property or in which the Common Stock (or other applicable security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of stockholders entitled to receive such cash, securities or other property (whether such date is fixed by the Board of Directors or by statute, contract or otherwise). (5) "trading day" shall mean (x) if the applicable security is listed or admitted for trading on the New York Stock Exchange or another national securities exchange, a day on which the New York Stock Exchange or another national securities exchange is open for business or (y) if the applicable security is quoted on the Nasdaq National Market, a day on which trades may be made thereon or (z) if the applicable security is not so listed, admitted for trading or quoted, any day other than a Saturday or Sunday or a day on which banking institutions in the State of New York are authorized or obligated by law or executive order to close. (h) The Company may make such adjustments in the Conversion Rate, in addition to those required by Sections 12.05(a), (b), (c), (d), (e) and (f), as the Board of Directors considers to be advisable to avoid or diminish any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any dividend or distribution of stock (or rights to acquire stock) or from any event treated as such for income tax purposes. The Company from time to time may, to the extent permitted by law and subject to the applicable rules of the Nasdaq National Market, increase the Conversion Rate of the Notes by any amount for any period of at least 20 days, if the Board of Directors has made a determination that such increase would be in the Company's best interests, which determination shall be conclusive and described in a resolution of the Board of Directors. The increase in Conversion Rate shall be irrevocable during this period. Whenever the Conversion Rate is increased pursuant to the preceding sentence, the Company shall mail to the holders of Notes at his or her last address appearing on the Register of holders maintained for that purpose a notice of the increase at least 15 days prior to the date the increased Conversion Rate takes effect, and such notice shall state the increased Conversion Rate and the period during which it will be in effect. (i) With respect to any rights or warrants (the "Rights") that may be issued or distributed pursuant to any rights plan that the Company implements after the date of this Indenture (each a "Rights Plan"), in lieu of any adjustment required by any other provision of this Section 12.05 upon conversion of the Notes into Common Stock, to the extent that such Rights Plan is in effect upon such conversion, the holders of Notes will receive, with respect to the shares of Common Stock issued upon conversion, the Rights described therein (whether or not the Rights have separated from the Common Stock at the time of conversion), subject to the limitations set forth in and in accordance with any such Rights Plan; provided that if, at the time of conversion, however, the Rights have separated from the shares of Common Stock in accordance with the provisions of the Rights Plan so that holders would not be entitled to receive any rights in respect of the shares of Common Stock issuable upon conversion of the Notes as a result of the timing of the Conversion Date, the Conversion Rate will be adjusted as if the Company distributed to all holders of Common Stock Distributed Securities as provided Section 12.05(d), 46

subject to appropriate readjustment in the event of the expiration, termination, repurchase or redemption of the Rights. Any distribution of rights or warrants pursuant to a Rights Plan complying with the requirements set forth in the immediately preceding sentence of this paragraph shall not constitute a distribution of rights or warrants pursuant to this Section 12.05. Other than as specified in this clause (i), there will not be any adjustment to the Conversion Rate as the result of the issuance of any Rights, the distribution of separate certificates representing such Rights, the exercise or redemption of such Rights in accordance with any Rights Plan or the termination or invalidation of any Rights. (j) No adjustment in the Conversion Rate shall be required unless such adjustment would require an increase or decrease of at least 1% in such price; provided, however, that any adjustments which by reason of this Section 12.05(j) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Article XII shall be made by the Company and shall be made to the nearest cent or to the nearest one hundredth of a share, as the case may be. No adjustment need be made for a change in the par value or no par value of the Common Stock. (k) Whenever the Conversion Rate is adjusted as herein provided, the Company shall promptly file with the Trustee and any Conversion Agent other than the Trustee an Officers' Certificate setting forth the Conversion Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice of such adjustment of the Conversion Rate to each holder of Notes at his or her last address appearing on the Register of holders maintained for that purpose within 20 days of the effective date of such adjustment. Failure to deliver such notice shall not affect the legality or validity of any such adjustment. (l) In any case in which this Section 12.05 provides that an adjustment shall become effective immediately after a Record Date for an event, the Company may defer until the occurrence of such event issuing to the holder of any Note converted after such Record Date and before the occurrence of such event the additional shares of Common Stock issuable upon such conversion by reason of the adjustment required by such event over and above the Common Stock issuable upon such conversion before giving effect to such adjustment. (m) For purposes of this Section 12.05, the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make any distribution on shares of Common Stock held in the treasury of the Company. SECTION 12.06. Effect of Recapitalization, Reclassification, Consolidation, Merger, Combination, Sale, Lease or Transfer. In the event of any (i) recapitalization, reclassification or change of the outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), (ii) consolidation, merger or combination of the Company with another corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination thereof) with respect to or in exchange for such Common Stock, or (iii) sale, lease or other transfer of the properties and assets of the Company and its Subsidiaries as an entirety or substantially as an entirety to 47

any other corporation as a result of which holders of Common Stock shall be entitled to receive stock, securities or other property or assets (including cash or any combination thereof) with respect to or in exchange for such Common Stock, then the Company or the successor or purchasing corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which shall comply with the TIA as in force at the date of execution of such supplemental indenture if such supplemental indenture is then required to so comply) providing that holders of Notes shall thereafter be entitled to convert Notes into the kind and amount of shares of stock and other securities or property or assets (including cash or any combination thereof) that such holders would have owned or otherwise been entitled to receive upon such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease or other transfer had such Notes been converted into shares of Common Stock immediately prior to such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease or other transfer (subject to the right of such holder to receive the Make Whole Premium (as defined in Section 12.11) upon compliance with the provisions of such Section)). In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in a recapitalization, reclassification, change, consolidation, merger combination, sale, lease or other transfer, the Company will make adequate provision whereby holders of the Notes shall have the opportunity, on a timely basis, to determine the form of consideration into which all of the Notes, treated as a single class, shall be convertible. Such determination shall be based on the blended, weighted average of elections made by holders of the Notes who participate in such determination and shall be subject to any limitations to which all of the holders of Common Stock are subject to, such as pro rata reductions applicable to any portion of the consideration payable. The Company shall not become party to any such recapitalization, reclassification, change, consolidation, merger combination, sale, lease or other transfer unless the terms of such transaction are consistent with the foregoing. Such supplemental indenture shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Article XII. If, in the case of any such reclassification, change, consolidation, merger, combination, sale, lease or other transfer, the stock or other securities and assets receivable thereupon by a holder of shares of Common Stock includes shares of stock or other securities and assets of a corporation other than the successor or purchasing corporation, as the case may be, in such recapitalization, reclassification, change, consolidation, merger, combination, sale, lease or other transfer, then such supplemental indenture shall also be executed by such other corporation and shall contain such additional provisions to protect the interests of the holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing. The Company shall cause notice of the execution of such supplemental indenture to be mailed to each holder of Notes at his or her address appearing on the Register of holders for that purpose within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture. The above provisions of this Section 12.06 shall similarly apply to successive reclassifications, changes, consolidations, mergers, combinations, sales, leases or other transfers. If this Section 12.06 applies to any event or occurrence, Section 12.05 shall not apply. SECTION 12.07. Taxes on Shares Issued. The issue of stock certificates on conversions of Notes shall be made without charge to the converting holder for any tax in respect of the issue thereof. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than that of the holder of any Note converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of 48

such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid. SECTION 12.08. Reservation of Shares; Shares to Be Fully Paid; Listing of Common Stock. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares to provide for the conversion of the Notes from time to time as such Notes are presented for conversion. Before taking any action which would cause an adjustment increasing the Conversion Rate to a level such that the Conversion Price would be below the then par value, if any, of the shares of Common Stock issuable upon conversion of the Notes, the Company shall take all corporate action which may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue shares of such Common Stock at such adjusted Conversion Rate; provided, however, that no shares of Common Stock shall be required to be issued at a Conversion Price less than the par value of such Common Stock. The Company covenants that all shares of Common Stock issued upon conversion of Notes will be fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. The Company further covenants that as long as the Common Stock is quoted on the Nasdaq National Market, or its successor, the Company shall cause all Common Stock issuable upon conversion of the Notes to be eligible for such quotation in accordance with, and at the times required under, the requirements of such market, and if at any time the Common Stock becomes listed on the New York Stock Exchange or any other national securities exchange, the Company shall cause all Common Stock issuable upon conversion of the Notes to be so listed and kept listed. SECTION 12.09. Responsibility of Trustee. The Trustee shall not at any time be under any duty of responsibility to any holders of Notes to determine whether any facts exist which may require any adjustment of the Conversion Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee shall not be accountable with respect to the validity or value (or the kind or amount) of any shares of Common Stock, or of any securities or property, which may at any time be issued or delivered upon the conversion of any Note; and the Trustee makes no representations with respect thereto. Subject to the provisions of Section 7.01, the Trustee shall not be responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article XII. Without limiting the generality of the foregoing, the Trustee shall not have any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 12.06 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by holders of Notes upon the conversion of their Notes after any event referred to in such Section 12.06 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept as conclusive evidence of the correctness of any such provisions, and shall be protected in relying upon, the Officers' Certificate and Opinion of Counsel (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. SECTION 12.10. Notice to Holders Prior to Certain Actions. If 49

(a) the Company declares a dividend (or any other distribution) on its Common Stock (other than in cash out of retained earnings); or (b) the Company authorizes the granting to the holders of its Common Stock of rights or warrants to subscribe for or purchase any share of any class of Common Stock or any other rights or warrants; or (c) there is any reclassification of the Common Stock (other than a subdivision or combination of outstanding Common Stock, or a change in par value, or from par value to no par value, or from no par value to par value), or of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (d) there is any voluntary or involuntary dissolution, liquidation or winding-up of the Company; then the Company shall cause to be filed with the Trustee and to be mailed to each holder of Notes at his or her address appearing on the Register maintained for that purpose as promptly as possible but in any event at least 15 days prior to the applicable date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution or rights or warrants, or, if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or occur, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. SECTION 12.11. Make Whole Premium Upon a Change of Control. If there shall have occurred (a) a transaction described in clause (a) or (b) of the definition of a Change of Control, or (b) a transaction that, but for the 105% trading price exception contained in clause (x) of the proviso to such definition would be a Change of Control, the Company shall pay a "Make Whole Premium" to the Holders of the Notes who surrender their Notes for conversion during the period beginning 10 trading days before the anticipated effective date of the Change of Control transaction (the "Effective Date" which shall be announced by the Company in any notice or release announcing the applicable change of control transaction) and ending at the close of business on the business day immediately preceding the Designated Event Payment Date by increasing the applicable Conversion Rate for such Notes by a number of additional shares of Common Stock per $1,000 principal amount of Notes, as determined by reference to the table below, based on the Effective Date and the price (the "Stock Price") paid per share of Common Stock in such transaction on such Effective Date; provided that if the Stock Price or Effective Date are not set forth on the table: (i) if the actual Stock Price on the Effective Date is between two Stock Prices on the table or the actual Effective Date is between two Effective Dates on the table, the Make Whole Premium will be determined by a straight-line interpolation between the Make Whole Premiums set forth for the two Stock Prices and the two Effective Dates on the table based on a 365-day year, as applicable, (ii) if the Stock Price on the Effective Date equals or exceeds $40 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid, and (iii) if the Stock Price on the Effective Date is less than $11.22 per share, subject to adjustment as set forth herein, no Make Whole Premium will be paid. If Holders of the Common Stock receive only cash in the Change of Control transaction, the Stock Price shall be the cash amount paid per share of the 50

Common Stock in connection with the Change of Control transaction. Otherwise, the Stock Price shall be equal to the average Closing Prices of the Common Stock for each of the 10 trading days immediately preceding, but not including, the applicable Effective Date.

The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The number of additional shares set forth in the table above will be adjusted in the same manner as the Conversion Rate as set forth in Section 12.05 hereof, other than as a result of an adjustment of the Conversion Rate by adding the Make Whole Premium as described above. For purposes of giving effect to the Make Whole Premium, the Conversion Price of the Notes following payment of the Make Whole Premium shall be equal to the product of (a) the Conversion Price immediately prior to payment of the Make Whole Premium and (b) the fraction obtained by dividing (i) the Conversion Rate immediately prior to payment of the Make Whole Premium by (ii) the Conversion Rate immediately after payment of the Make Whole Premium. Notwithstanding the foregoing paragraphs, in no event will the total number of shares of Common Stock issuable upon conversion of a Note exceed 89.1265 per $1,000 principal amount of Notes, subject to proportional adjustment in the same manner as the Conversion Price as set forth in clauses (a) through (d) of Section 12.05 hereof. By delivering the amount of cash and/or the number of shares of Common Stock issuable on conversion to the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the Notes so converted and its obligation to pay accrued and unpaid interest attributable to the period from the most recent Interest Payment Date through the date of conversion (which amount will be deemed paid in full rather than cancelled, extinguished or forfeited). 51

News Release
Amkor Closes Offering of 9.25% Senior Notes Due 2016 and
Associated Tender Offer for 9.25% Senior Notes due 2008;

Also Closes Offering of 2.50% Convertible Senior Subordinated Notes Due 2011
CHANDLER, Ariz. — May 31, 2006 — Amkor Technology, Inc. (Nasdaq: AMKR) today announced that it has closed an offering of $400 million aggregate principal amount of its 9.25% senior notes due 2016 (the “Senior Notes”) together with the associated cash tender offer, dated April 28, 2006 (as supplemented) for its 9.25% senior notes due 2008. As of midnight on May 25, 2006, the expiration date for the tender offer, approximately $352 million aggregate principal amount of Amkor’s 9.25% Senior Notes due 2008 had been tendered, all of which were accepted for payment by Amkor.
Net proceeds of $382 million from the offering of Senior Notes were used to purchase notes that were tendered pursuant to the tender offer, and to pay the related tender premium, accrued and unpaid interest, early tender payment and related fees and expenses. The remaining net proceeds of approximately $11 million will be used to pay other debt obligations and for working capital and general corporate purposes.
Amkor also announced that it has closed an offering of $190 million aggregate principal amount of its 2.50% convertible senior subordinated notes due 2011 (the “Convertible Notes”). Amkor intends to use the net proceeds from the offering of Convertible Notes to redeem, repurchase or otherwise retire a portion (or, if the underwriter exercises its option to purchase additional notes in full, all) of the $200 million aggregate principal amount outstanding of Amkor’s 10.5% senior subordinated notes due 2009 (together with the payment of the related premium, accrued and unpaid interest to and including the redemption date and related fees and expenses). Amkor intends to use any remaining net proceeds from the offering of the Convertible Notes to pay its other debt obligations and for working capital and general corporate purposes.
The Convertible Notes are convertible at any time by the holders thereof into shares of Amkor’s common stock at an initial conversion rate of 68.5589 shares of common stock per $1,000 principal amount of Convertible Notes (which represents an initial conversion price of $14.59 per share), subject to adjustment. As previously announced, Amkor has granted the underwriter, Citigroup Global Markets Inc., an option to purchase up to an additional $28.5 million aggregate principal amount of Convertible Notes, which is exercisable on or prior to June 9, 2006.
“Our repurchase of $352 million in senior notes due 2008, coupled with the scheduled retirement of our outstanding $132 million of convertible notes at maturity on June 1, 2006, marks progress in addressing our intermediate term debt maturities,” said Ken Joyce, Amkor’s chief financial officer. “In connection with the retirement of a portion of the 9.25% senior notes due 2008 in the tender offer, we expect to record a charge, with no net tax effect, of approximately $23 million, or $0.11 per diluted share, in the second quarter of 2006.”
