“Fixed Charge Coverage Ratio” means, with respect to any Person for any period consisting of such Person and its Restricted Subsidiaries’ most recently ended four fiscal quarters for which internal financial statements are available, the ratio of EBITDA of such Person for such period to the Fixed Charges of such Person for such period. In the event that the Issuer or any Restricted Subsidiary incurs, assumes, guarantees or redeems any Indebtedness or issues or repays Disqualified Stock or Preferred Stock subsequent to the commencement of the period for which the Fixed Charge Coverage Ratio is being calculated but on or prior to the event for which the calculation of the Fixed Charge Coverage Ratio is made (the “Calculation Date”), then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee or repayment of Indebtedness, or such issuance or redemption of Disqualified Stock or Preferred Stock, as if the same had occurred at the beginning of the applicable four-quarter period.

For purposes of making the computation referred to above, Investments, acquisitions, dispositions, mergers, consolidations and discontinued operations (as determined in accordance with GAAP) that have been made by the Issuer or any Restricted Subsidiary during the four-quarter reference period or subsequent to such reference period and on or prior to or simultaneously with the Calculation Date shall be calculated on a pro forma basis assuming that all such Investments, acquisitions, dispositions, mergers, consolidations and discontinued operations (and the change in any associated fixed charge obligations and the change in EBITDA resulting therefrom) had occurred on the first day of the four-quarter reference period.

If since the beginning of such period any Person (that subsequently became a Restricted Subsidiary or was merged with or into the Issuer or any Restricted Subsidiary since the beginning of such period) shall have made any Investment, acquisition, disposition, merger, consolidation or discontinued operation that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage Ratio shall be calculated giving pro forma effect

thereto for such period as if such Investment, acquisition, disposition, merger, consolidation or discontinued operation had occurred at the beginning of the applicable four-quarter period.

For purposes of this definition, whenever pro forma effect is to be given to an acquisition or other Investment and the amount of income or earnings relating thereto, the pro forma calculations shall be determined in good faith by a responsible financial or accounting Officer of the Issuer and shall comply with the requirements of Rule 11-02 of Regulation S-X promulgated by the Commission, except that such pro forma calculations may include (1) all adjustments commonly used by the Parent Guarantor in connection with the calculation of “Operating EBITDA” (i.e., net earnings less interest income plus loss (earnings) from discontinued operations, interest expense, taxes, and depreciation and amortization, and further adjusted for other charges and adjustments such as employee termination benefits, costs from plant closures and relocations) to the extent such adjustments, without duplication, continue to be applicable to such four-quarter period, and (2) operating expense reductions for such period resulting from the acquisition which is being given pro forma effect that have been realized or for which the steps necessary for realization have been taken or are reasonably expected to be taken within six months following any such acquisition, including, but not limited to, the execution or termination of any contracts, the termination of any personnel or the closing (or approval by the Board of Directors of any closing) of any facility, as applicable, provided that, in either case, such adjustments are set forth in an Officer’s Certificate signed by the Issuer’s chief financial officer and another Officer which states (i) the amount of such adjustment or adjustments, (ii) that such adjustment or adjustments are based on the reasonable good faith beliefs of the Officers executing such Officer’s Certificate at the time of such execution and (iii) that any related incurrence of Indebtedness is permitted pursuant to the Indenture. If any Indebtedness bears a floating rate of interest and is being given pro forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligations applicable to such Indebtedness).

Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by a responsible financial or accounting officer of the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under a revolving credit facility computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness during the applicable period. Interest on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional rate chosen as the Issuer may designate.

“Fixed Charges” means, with respect to any Person for any period, the sum of, without duplication, (a) Consolidated Interest Expense of such Person for such period, (b) all cash dividends paid, accrued and/or scheduled to be paid or accrued during such period (excluding items eliminated in consolidation) on any series of Preferred Stock of such Person and (c) all cash dividends paid, accrued and/or scheduled to be paid or accrued during such period (excluding items eliminated in consolidation) of any series of Disqualified Stock.

(2) in the case of any Lien securing Subordinated Indebtedness, effective provision is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same assets of the Issuer or such Restricted Subsidiary, as the case may be, that is prior to the Lien securing such Subordinated Indebtedness.

So long as the Parent Guarantor is a Guarantor (there being no obligation of the Parent Guarantor to do so), holds no material assets other than cash, Cash Equivalents and the Capital Stock of the Issuer (and performs the related incidental activities associated with such ownership) and complies with the requirements of Rule 3-10 of Regulation S-X promulgated by the Commission (or any successor provision), the reports, information and other documents required to be filed and furnished to holders of the Notes pursuant to this Section 4.8 may, at the option of the Issuer, be filed by and be those of the Parent Guarantor rather than the Issuer.

The availability of the foregoing reports on the Commission’s ▇▇▇▇▇ service (or successor thereto) shall be deemed to satisfy the Issuer’s delivery obligations to the Trustee and holders.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Issuer’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

SECTION 4.9. Change of Control Event.

(a) If a Change of Control Event occurs, each Holder will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer on the terms set forth in the Indenture. In the Change of Control Offer, the Issuer shall offer to purchase such Notes at a purchase price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(b) Within 30 days following any Change of Control Event, the Issuer will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering (the “Change of Control Offer”) to repurchase Notes on the date specified in the notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the Indenture and described in such notice. Such notice shall state:

(1) that a Change of Control Event has occurred and that such Holder has the right to require the Issuer to purchase all or a portion of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase (subject to the right of the Holders of record on the relevant record date to receive interest on the relevant interest payment date);

(2) the circumstances and relevant facts and financial information regarding such Change of Control Event;

(3) the Change of Control Payment Date; and

(4) the instructions determined by the Issuer, consistent with this Section, that a Holder must follow in order to have its Notes purchased.

(c) Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the Change of Control Purchase Date. The Holders shall be entitled to withdraw their election if the Trustee or the Issuer receives not later than one Business Day prior to the Change of Control Purchase Date a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered for purchase by the Holder and a statement that such Holder is withdrawing his election to have such Note purchased. Holders whose Notes are purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

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

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

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

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

(e) On the Change of Control Purchase Date all Notes purchased by the Issuer under this Section shall be delivered to the Trustee for cancellation, and the Issuer shall pay the Change of Control Payment to the Holders entitled thereto.

(f) The paying agent will promptly mail to each holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof.

(g) The Issuer shall not be required to make a Change of Control Offer upon a Change of Control Event if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.9 applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (2) notice of redemption has been given pursuant to the Indenture as described above under Section 3.1, unless and until there is a default in the payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control Event or conditional upon the occurrence of a Change of Control Event, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made and such Change of Control Offer is otherwise made in compliance with the provisions of this Section 4.9.

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

SECTION 4.10. Asset Sales.

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

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

(2) at least 75% of the consideration received in the Asset Sale by the Issuer or such Restricted Subsidiary is in the form of cash or Cash Equivalents.

For purposes of clause (2) above and for no other purpose, the amount of (i) any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto) of the Issuer or any Restricted Subsidiary (other than liabilities that are by their terms subordinated to the Notes or the Guarantees) that are assumed by the transferee of any such assets, (ii) any securities received by the Issuer or such Restricted Subsidiary from such transferee that are converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash received) within 180 days following the receipt thereof, (iii) the fair market value (as

determined in good faith by the Issuer) of (A) any assets (other than securities) received by the Issuer or any Restricted Subsidiary to be used by it in a Permitted Business, (B) Equity Interests in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the acquisition of such Person by the Issuer or any Restricted Subsidiary or (C) a combination of (A) and (B), and (iv) any Designated Non-cash Consideration received by the Issuer or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value (as determined in good faith by the Issuer), taken together with all other Designated Non-cash Consideration received pursuant to this clause (iv) that is at that time outstanding, not to exceed 5.0% of Total Assets at the time of the receipt of such Designated Non-cash Consideration (with the fair market value of each item of Designated Non-cash Consideration being measured at the time received without giving effect to subsequent changes in value) shall be deemed to be cash.

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

(1) permanently reduce Obligations under Secured Debt of the Issuer or a Guarantor (and to correspondingly reduce commitments with respect thereto) or Indebtedness of a Restricted Subsidiary that is not a Guarantor, in each case other than Indebtedness owed to the Issuer or a Subsidiary of the Issuer;

(2) make an investment in (A) any one or more businesses; provided that such investment in any business is in the form of the acquisition of Capital Stock and results in the Issuer or a Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) capital expenditures or (C) other assets, in each of (A), (B) and (C), used or useful in a Permitted Business; and/or

(3) make an investment in (A) any one or more businesses; provided that such investment in any business is in the form of the acquisition of Capital Stock and it results in the Issuer or a Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (B) properties or (C) assets that, in each of (A), (B) and (C), replace the businesses, properties and assets that are the subject of such Asset Sale.

Any Net Proceeds from an Asset Sale not applied or invested in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Proceeds shall constitute “Excess Proceeds,” provided that if during such 365-day period the Issuer or a Restricted Subsidiary enters into a definitive binding agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2) or (3) of the immediately preceding paragraph after such 365th day, such 365-day period will be extended with respect to the amount of Net Proceeds so committed for a period not to exceed 180 days until such Net Proceeds are required to be applied in accordance with such agreement (or, if earlier, until termination of such agreement).

When the aggregate amount of Excess Proceeds exceeds $40.0 million, the Issuer or the applicable Restricted Subsidiary will make an offer (an “Asset Sale Offer”) to all holders

of Notes and, at the option of the Issuer, Indebtedness that ranks pari passu with the Notes and contains provisions similar to those set forth in the Indenture with respect to mandatory prepayments, redemptions or offers to purchase with the proceeds of sales of assets, to purchase, on a pro rata basis, the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. The Issuer shall commence an Asset Sale Offer with respect to Excess Proceeds within ten Business Days after the date that Excess Proceeds exceed $40.0 million by mailing the notice required pursuant to the terms of Section 4.10(f), with a copy to the Trustee.

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

If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Issuer or the applicable Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(c) The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the Indenture, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Asset Sale provisions of this Section 4.10 by virtue of such conflict.

(d) Not later than the date upon which written notice of an Asset Sale Offer is delivered to the Trustee as provided above, the Issuer shall deliver to the Trustee an Officer’s Certificate as to (i) the amount of the Excess Proceeds, (ii) the allocation of the Net Proceeds from the Asset Sales pursuant to which such Asset Sale Offer is being made and (iii) the compliance of such allocation with the provisions of Section 4.10(b). On such date, the Issuer shall also irrevocably deposit with the Trustee or with a Paying Agent (or, if the Issuer or a Subsidiary is acting as a Paying Agent, such Paying Agent shall segregate and hold in trust) an amount equal to the Excess Proceeds to be invested in Cash Equivalents, as directed in writing by the Issuer, and to be held for payment in accordance with the provisions of this Section 4.10. Upon the expiration of the period for which the Asset Sale Offer remains open (the “Offer Period”), the Issuer shall deliver to the Trustee for cancellation the Notes or portions thereof that have been properly tendered to and are to be accepted by the Issuer. The Trustee (or a Paying Agent, if not the Trustee) shall, on the date of purchase, mail or deliver payment to each tendering Holder in the amount of the purchase price. In the event that the Excess Proceeds delivered by the Issuer to the Trustee is greater than the purchase price of the Notes tendered, the Trustee shall deliver the excess to the Issuer immediately after the expiration of the Offer Period for application in accordance with Section 4.10.

(e) Holders electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuer at the address specified in the notice at least three Business Days prior to the purchase date. Holders shall be entitled to withdraw their election if the Trustee or the Issuer receives not later than one Business Day prior to the Purchase Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered by the Holder for purchase and a statement that such Holder is withdrawing his election to have such Note purchased. If at the end of the Offer Period more Notes are tendered pursuant to an Asset Sale Offer than the Issuer is required to purchase, selection of such Notes for purchase shall be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed, or if such Notes are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate (and in such manner as complies with applicable legal requirements); provided that no Notes of $1,000 or less shall be purchased in part.

(f) Notices of an Asset Sale Offer shall be mailed by first class mail, postage prepaid, at least 30 but not more than 60 days before the purchase date to each Holder of Notes at such Holder’s registered address. If any Note is to be purchased in part only, any notice of purchase that relates to such Note shall state the portion of the principal amount thereof that is to be purchased.

(g) A new Note in principal amount equal to the unpurchased portion of any Note purchased in part shall be issued in the name of the Holder thereof upon cancellation of the original Note. On and after the purchase date, unless the Issuer defaults in payment of the purchase price, interest shall cease to accrue on Notes or portions thereof purchased.

SECTION 4.11. Suspension of Covenants.

(a) During any period of time (a “Suspension Period”) after the Issue Date that (i) the Notes have Investment Grade Ratings from each of S&P and ▇▇▇▇▇’▇ (or, if either (or both) of S&P and ▇▇▇▇▇’▇ have been substituted in accordance with the definition of “Rating Agencies”, by each of the then applicable Rating Agencies) and (ii) no Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”), the Issuer and its Restricted Subsidiaries will not be subject to Sections 4.1, 4.2, 4.4, 4.5, 4.6, 4.10 and 5.1(a)(4) (the “Suspended Covenants”). Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds from Net Proceeds shall be reset at zero.

(b) In the event that the Issuer and its Restricted Subsidiaries are not subject to the Suspended Covenants for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) the condition set forth in clause (i) of Section 4.11(a) is no longer satisfied, then the Issuer and its Restricted Subsidiaries will thereafter again be subject to the Suspended Covenant with respect to future events. In the event of any such reinstatement, no Default or Event of Default will be deemed to have occurred as a result of a failure to comply with the Suspended Covenants during a Suspension Period (or on the Reversion Date or after the Suspension Period based solely on events that occurred during the Suspension Period).

(c) On each Reversion Date, all Indebtedness incurred during the Suspension Period prior to such Reversion Date will be deemed to be Existing Indebtedness. For purposes of calculating the amount available to be made as Restricted Payments under Section 4.1(a)(3), calculations under Section 4.1 shall be made as though such covenant had been in effect during the entire period of time after the Issue Date (including the Suspension Period). Restricted Payments made during the Suspension Period not otherwise permitted pursuant to section 4.1(b) will reduce the amount available to be made as Restricted Payments under Section 4.1(a)(3).

ARTICLE FIVE

MERGER, CONSOLIDATION OR SALE OF ASSETS

With respect to the Notes, the following shall supersede the provisions of Article V of the Base Indenture; provided that the terms of this Article Five shall not become a part of the terms of any other series of Securities.

(5) each Guarantor, unless it is the other party to the transactions described above, in which case clause (2) shall apply, shall have confirmed in writing that its Guarantee shall apply to such Person’s obligations under the Notes and the Indenture; and

SECTION 5.2. Consolidation, Merger and Sale of Assets by a Guarantor.

(a) Subject to the provisions described under Section 6.4(a), no Guarantor (other than the Parent Guarantor) shall consolidate or merge with or into or wind up into (whether or not such Guarantor is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person, unless:

(1) such Guarantor is the surviving Person or the Person formed by or surviving any such consolidation or merger (if other than such Guarantor) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the United States, any state thereof, the District of Columbia or any territory thereof (such Guarantor or such Person, as the case may be, being herein called the “Successor Guarantor”);

(4) the Issuer shall have delivered to the Trustee a certificate from a Responsible Officer and an Opinion of Counsel, each stating that such consolidation, merger or transfer and such amendment or supplement (if any) comply with the Indenture.

ARTICLE SIX

GUARANTEE OF NOTES

SECTION 6.1. Guarantee.

Subject to the provisions of this Article Six, each Guarantor, by execution of this First Supplemental Indenture, jointly and severally, unconditionally guarantees to each Holder (i) the due and punctual payment of the principal of, premium, if any, and interest on each Note, when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal of, premium, if any, and, to the extent permitted by law, interest on the Notes, to the extent lawful, and the due and punctual payment of all other Obligations and due and punctual performance of all obligations of the Issuer to the Holders or the Trustee all in accordance with the terms of such Note and the Indenture, and (ii) in the case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, at stated maturity, by acceleration or otherwise. Each Guarantor, by execution of this First Supplemental Indenture, agrees that its obligations hereunder shall be absolute and unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of any such Note or the Indenture, any failure to enforce the provisions of any such Note or the Indenture, any waiver, modification or indulgence granted to the Issuer with respect thereto by the Holder of such Note, or any other circumstances which may otherwise constitute a legal or equitable discharge of a surety or such Guarantor.

Each Guarantor hereby waives diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest or notice with respect to any such Note or the Indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged as to any such Note except by payment in full of the principal thereof and interest thereon. Each Guarantor hereby agrees that, as between such Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (i) subject to this Article Six, the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Seven for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (ii) in the event

of any declaration of acceleration of such Obligations as provided in Article Seven, such Obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee.

SECTION 6.2. Execution and Delivery of Notation of Guarantee.

To further evidence the Guarantee set forth in Section 6.1, each Guarantor hereby agrees that a notation of such Guarantee, substantially in the form included in Exhibit II hereto, shall be endorsed on each Note authenticated and delivered by the Trustee and such Guarantee shall be executed by either manual or facsimile signature of an Officer or an Officer of a general partner, as the case may be, of each Guarantor. The validity and enforceability of any Guarantee shall not be affected by the fact that it is not affixed to any particular Note.

Each Guarantor hereby agrees that its Guarantee set forth in Section 6.1 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

If an Officer of a Guarantor whose signature is on the Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such Guarantee is endorsed or at any time thereafter, such Guarantor’s Guarantee of such Note shall be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in the Indenture on behalf of each Guarantor.

SECTION 6.3. Limitation of Guarantee.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of any 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 Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor are limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Each Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Guarantor in a pro rata amount based on the assets of each Guarantor.

SECTION 6.4. Release of Guarantor.

(a) A Guarantor shall be automatically and unconditionally released from all of its obligations under its Guarantee if:

(1) (A) all of its assets or Capital Stock is sold or transferred, in each case in a transaction in compliance with Section 4.10,

(B) the Guarantor merges with or into, or consolidates with or amalgamates with, or transfers all or substantially all of its assets to, another Person in compliance with Article Five,

(D) in connection with any (direct or indirect) sale of Capital Stock or other transaction that results in the Subsidiary Guarantor ceasing to be a Subsidiary of the Issuer, if the sale or other transaction complies with the provisions of Section 4.10, or

(E) upon legal defeasance of the notes or satisfaction and discharge of the Indenture as provided under Article VIII of the Base Indenture;

(2) such Guarantor has delivered to the Trustee a certificate of a Responsible Officer and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to such transaction have been complied with; and

(3) such Guarantor is released from its guarantee of the Credit Agreement.

(b) The Guarantee of the Parent Guarantor may be released at any time upon the option of the Issuer and the Parent Guarantor.

(c) The Trustee shall execute any documents reasonably requested by the Issuer or a Guarantor in order to evidence the release of such Guarantor from its obligations under its Guarantee endorsed on the Notes and under this Article Six.

SECTION 6.5. Waiver of Subrogation.

Each Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement of such Guarantor’s obligations under its Guarantee and the Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Issuer, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Holders, and shall forthwith be paid to the Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of the Indenture. Each Guarantor acknowledges that it will receive direct and indirect

benefits from the financing arrangements contemplated by the Indenture and that the waiver set forth in this Section 6.5 is knowingly made in contemplation of such benefits.

ARTICLE SEVEN

EVENTS OF DEFAULT

SECTION 7.1. Events of Default.

(a) With respect to the Notes, Section 6.1 of the Base Indenture shall be replaced in its entirety with the following, which shall be deemed to be provisions of the Base Indenture with respect to the Notes; provided that the terms of this Article Seven shall not become a part of the terms of any other series of Securities:

ARTICLE EIGHT

SATISFACTION AND DISCHARGE

With respect to the Notes, Article VIII of the Base Indenture shall be superseded in its entirety by the following language with respect to, and solely for the benefit of the Holders of the Notes; provided that this Article Eight shall not become part of the terms of any other series of Securities:

SECTION 8.1. Discharge of Liability on Notes.

The Indenture shall be discharged and shall cease to be of further effect (except as to surviving rights of registration of transfer or exchange of Notes, as expressly provided for in the Indenture) as to all outstanding Notes:

(a) when either:

(1) all the Notes theretofore authenticated and delivered (other than Notes which have been replaced pursuant to Section 2.8 of the Base Indenture or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation; or

(2) all of the Notes (A) have become due and payable, (B) will become due and payable at their stated maturity within one year or (C) if redeemable at the option of the Issuer, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-

callable Government Securities in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(b) the Issuer and/or the Guarantors has paid or caused to be paid all sums payable by them under the Indenture;

(c) the Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be; and

(d) the Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

SECTION 8.2. Defeasance.

(a) The Issuer may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Notes issued under the Indenture (“Legal Defeasance”) except for:

(1) the rights of holders of outstanding Notes issued thereunder to receive payments in respect of the principal of, or interest or premium, if any, on such Notes when such payments are due from the trust referred to below;

(2) the Issuer’s obligations with respect to the Notes issued thereunder concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Issuer’s obligations in connection therewith; and

(4) this Section 8.2(a).

(b) The Issuer may, at its option and at any time, elect to have its obligations released with respect to Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.10 and 4.11 of this First Supplemental Indenture and the operation of Article Five and Sections 6.1(c), 6.1(d), 6.1(e), 6.1(f) (with respect to Significant Subsidiaries of the Issuer only), 6.1(g) (with respect to Significant Subsidiaries of the Issuer only) and 6.01(h) (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the Notes. The Issuer may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option.

If the Issuer exercises its Legal Defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default. If the Issuer exercises its

Covenant Defeasance option, payment of the Notes so defeased may not be accelerated because of an Event of Default specified in Sections 6.1(c), 6.1(d), 6.1(e), 6.1(f) (with respect to Significant Subsidiaries of the Issuer only), 6.1(g) (with respect to Significant Subsidiaries of the Issuer only) and 6.1(h) or because of the failure of the Issuer to comply with Section 5.1.

Upon satisfaction of the conditions set forth herein and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

(c) Notwithstanding clauses (a) and (b) above, the Issuer’s obligations in Sections 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 7.6 and 7.7 of the Base Indenture and in this Article shall survive until the Notes have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.6, 8.6 and 8.7 of this First Supplemental Indenture shall survive such satisfaction and discharge.

SECTION 8.3. Conditions to Defeasance.

(a) The Issuer may exercise its Legal Defeasance option or its Covenant Defeasance option only if:

(1) the Issuer has irrevocably deposited with the Trustee, in trust, for the benefit of the holders of the Notes issued thereunder, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, or interest and premium, if any, on the outstanding Notes issued thereunder on the stated maturity or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are being defeased to maturity or to a particular redemption date;

(2) in the case of Legal Defeasance, the Issuer has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the holders of the respective outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

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

(4) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens in connection therewith);

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

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

(7) the Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance as contemplated by this Article Eight have been complied with.

(b) Before or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Notes at a future date in accordance with Article III.

SECTION 8.4. Application of Trust Money.

The Trustee shall hold in trust money or Government Securities (including proceeds thereof) deposited with it pursuant to this Article. It shall apply the deposited money and the money from Government Securities through each Paying Agent and in accordance with the Indenture to the payment of principal of and interest on the Notes so discharged or defeased.

SECTION 8.5. Repayment to Issuer.

Each of the Trustee and each Paying Agent shall promptly turn over to the Issuer upon request any money or Government Securities held by it as provided in this Article which, in the written opinion of nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall only be required if Government Securities have been so deposited), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article.

Subject to any applicable abandoned property law, the Trustee and each Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

SECTION 8.6. Indemnity for Government Securities.

The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited Government Securities or the principal and interest received on such Government Securities.

SECTION 8.7. Reinstatement.

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

ARTICLE NINE

AMENDMENTS AND WAIVERS

SECTION 9.1. Amendment, Supplement and Waiver.

(a) With respect to the Notes, Sections 9.1, 9.2 and 9.3 of the Base Indenture shall be replaced in their entirety with the following; provided that this Article Nine shall not become a part of the terms of any other series of Securities:

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

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

(3) to provide for the assumption of the Issuer’s obligations to holders of Notes in the case of a merger or consolidation or sale of all or substantially all of the assets of the Issuer and its Subsidiaries;

(4) to make any change that would provide any additional rights or benefits to the holders of Notes or that does not adversely affect the legal rights under the Indenture of any such holder;

(5) to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act;

(6) to add a Guarantee of the Notes;

(7) to release a Guarantor upon its sale or designation as an Unrestricted Subsidiary or other permitted release from its Guarantee; provided

that such sale, designation or release is in accordance with the applicable provisions of the Indenture; or

(8) to conform the text of any provision of the Indenture, the Notes or Guarantees to the extent such provision was intended to be a verbatim recitation of a provision in the “Description of the Notes” section in the Offering Memorandum, which intent shall be conclusively evidenced by an Officer’s Certificate to that effect.

After an amendment under this Section 9.1 becomes effective, the Issuer shall mail to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.1.

Section 9.2 With Consent of Holders. The Indenture or the Notes issued thereunder may be amended or supplemented with the consent of the holders of at least a majority in principal amount of the Notes then outstanding issued under the Indenture (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing default or compliance with any provision of the Indenture or the Notes issued thereunder may be waived with the consent of the holders of a majority in principal amount of the then outstanding Notes issued under the Indenture (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes). Without the consent of each Holder of an outstanding Note affected, an amendment or waiver may not (with respect to any Notes held by a non-consenting member):

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

(2) reduce the principal of or change the fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes (other than Sections 4.9 or 4.10 of the First Supplemental Indenture);

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

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

(6) make any change in Article Six of the First Supplemental Indenture that adversely affects the rights of any Holder under Article Six;

(7) make any changes in Section 6.8 or 6.13 hereof;

(8) waive a redemption payment with respect to any Note issued hereunder (other than Section 4.9 and 4.10 of the First Supplemental Indenture); or

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

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment, but it shall be sufficient if such consent approves the substance thereof.

After an amendment under this Section 9.2 becomes effective, the Issuer shall mail to the Holders a notice briefly describing such amendment. The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.2.

Section 9.3 Payment for Consent. The Issuer will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of the Indenture or the Notes unless such consideration is offered to be paid and 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.

(b) With respect to the Notes, Section 9.5 of the Base Indenture shall be amended such that the reference to “clauses (1) through (8) of Section 9.3” is a reference to “clauses (1) through (9) of Section 9.2”, which references shall be deemed to be provisions of the Base Indenture with respect to the Notes; provided that the terms of this Article Nine shall not become a part of the terms of any other series of Securities.

Subject to any applicable abandoned property law, if money for the payment of principal or interest held by the Trustee or a Paying Agent remains unclaimed for two years, the Trustee or a Paying Agent, as applicable, shall pay the money to the Issuer upon written request. Thereafter, Holders entitled to the money must look to the Issuer for payment as general creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

10. Discharge and Defeasance

Subject to certain conditions and limitations set forth in the Indenture, the Issuer may terminate some of or all its obligations under the Notes and the Indenture if the Issuer deposits with the Trustee money or U.S. Government Securities for the payment of principal of, premium, if any, and interest, on, the Notes to redemption or maturity, as the case may be.

11. Modification and Waiver

Subject to certain exceptions set forth in the Indenture, the Indenture and the Notes may be amended, or default may be waived, with the consent of the Holders of a majority in principal amount of the outstanding Notes. Without notice to or the consent of any Holder, the Issuer and the Trustee may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency.

12. Defaults and Remedies

If an Event of Default occurs (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuer set forth in the Indenture) and is continuing, the Trustee or the Holders of at least 25% in principal amount of the outstanding Notes, in each case, by notice to the Issuer, may declare the principal of, premium, if any, and accrued but unpaid interest on all the Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Issuer occurs, the principal of, premium, if any, and interest on all the Notes shall become immediately due and payable without any declaration or other act on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

13. Trustee Dealings with the Issuer

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Issuer or its Affiliates and, subject to the Indenture, may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee.
