“Consolidated Fixed Charge Coverage Ratio” means, with respect to any Person, the ratio of Consolidated EBITDA of such Person during the four full fiscal quarters for which financial statements are available (the “Four Quarter Period”) ending prior to the date of the transaction giving rise to the need to calculate the Consolidated Fixed Charge Coverage Ratio (the “Transaction Date”) to Consolidated Fixed Charges of such Person for the Four Quarter Period. In addition to and without limitation of the foregoing, for purposes of this definition, “Consolidated EBITDA” and “Consolidated Fixed Charges” shall be calculated after giving effect on a pro forma basis for the period of such calculation to:

(ii) any Asset Sales or Asset Acquisitions (including, without limitation, any Asset Acquisition giving rise to the need to make such calculation as a result of such Person or one of its Restricted Subsidiaries (including any Person who becomes a Restricted Subsidiary as a result of the Asset Acquisition) incurring, assuming or otherwise being liable for Acquired Debt and also including any Consolidated EBITDA attributable to the assets which are the subject of the Asset Acquisition) occurring during the Four Quarter Period or at any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or Asset Acquisition (including the incurrence, assumption or liability for any such Acquired Debt) occurred on the first day of the Four Quarter Period.

(b) Notwithstanding 4.07(a), the Parent and any one or more of its Restricted Subsidiaries may, without securing the Notes and the Guarantees, issue, assume or guarantee Debt secured by Liens which would not be permitted by Section 4.07(a) in an aggregate amount which, together with:

(1) the aggregate principal amount of all of the Parent’s other Debt and Debt of its Restricted Subsidiaries secured by a Lien upon any Principal Property or upon any shares of stock of any Restricted Subsidiary that would not be permitted to be secured by Liens under Section 4.07(a); and

(2) the Attributable Debt in respect of Sale and Lease-Back Transactions existing at such time (other than Sale and Lease-Back Transactions in which the property involved would have been permitted to be secured under Section 4.07(a) or the proceeds of which have been applied in accordance with Section 4.08(a)(2) to the retirement of long-term indebtedness);

(a) The Parent will not, nor will the Parent permit any Restricted Subsidiary to, enter into any arrangement with any Person providing for the leasing by the Parent or any Restricted Subsidiary of any Principal Property, except for (x) temporary leases for terms of not more than three years, (y) leasing arrangements between the Parent and a Subsidiary or (z) leasing arrangements between Subsidiaries, title to which property has been or is to be sold or transferred by the Parent or such Restricted Subsidiary to such Person (such transaction, a “Sale and Lease-Back Transaction”), unless the proceeds of any such sale are at least equal to the fair value, as determined by the Board of Directors of the Parent, of such property and either:

(1) the Parent or such Restricted Subsidiary would be permitted under Section 4.07(a) to secure Debt by a Lien on the Principal Property to be leased in an amount at least equal to the Attributable Debt in respect of such Sale and Lease-Back Transaction without equally and ratably securing the Notes pursuant to Section 4.07; or

(2) the Parent applies an amount equal to the fair value of the property so leased to the retirement, within 90 days of the effective date of any such Sale and Lease-Back Transaction, of the Issuer’s or the Parent’s long-term indebtedness which ranks senior or equal to the Notes or the related Guarantee (other than indebtedness held by the Parent or any of its Subsidiaries).

(b) Each Guarantee of a Subsidiary Guarantor shall be released in accordance with the provisions of Section 11.06.

(c) Any Subsidiary Guarantor that makes a payment under its Guarantee will be entitled upon payment in full of all obligations that are guaranteed under this Indenture to a contribution from each other Subsidiary Guarantor in an amount equal to such other Subsidiary Guarantor’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors at the time of such payment determined in accordance with GAAP.

Section 4.11 Limitation on Asset Sales.

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

(1) the Parent (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Capital Stock issued or sold or otherwise disposed of as determined by the Parent in good faith; and

(2) except in the case of a Permitted Asset Swap, at least 75% of the consideration received in the Asset Sale by the Parent or such Restricted Subsidiary is in the form of cash or Eligible Cash Equivalents.

For the purposes of this Section 4.11(a), the following will be deemed to be cash:

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

(ii) any securities, notes or other obligations received by the Parent or any such Restricted Subsidiary from such transferee that are converted by the Parent or such Restricted Subsidiary into cash within 180 days of their receipt to the extent of the cash received in that conversion; and

(iii) any Designated Non-cash Consideration received by the Parent or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value as determined by the Parent in good faith, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is at that time outstanding, not to exceed $50.0 million 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 and without giving effect to subsequent changes in value.

(b) Within 360 days after the receipt of any Net Cash Proceeds from an Asset Sale, the Parent (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Cash Proceeds at its option:

(A) to permanently repay (a) Debt under the Credit Agreement and, if the obligation repaid is revolving credit Debt, to correspondingly reduce commitments with respect thereto and/or (b) other unsecured Debt ranking pari passu in right of payment with the Notes or the Parent’s Guarantee of the Notes (provided that if the Parent shall so reduce obligations under such other unsecured Debt, other than the Notes, the Parent will (x) equally and ratably reduce obligations under the Notes under any applicable optional redemption provisions or by open market purchases or (y) make an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest and additional interest, if any, the pro rata principal amount of Notes);

(B) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Parent;

(C) to make a capital expenditure in or that is used or useful in a Permitted Business or to make expenditures for maintenance, repair or improvement of existing properties and assets;

(D) to acquire other assets (other than inventory) that are used or useful in a Permitted Business;

(E) to repay or repurchase Debt secured by the assets of the Parent or any Restricted Subsidiaries; or

(F) any combination of the foregoing.

(c) Any Net Cash Proceeds from Asset Sales that are not applied, invested or subject to an offer to repurchase as provided in Section 4.11(b) will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds with respect to the Notes exceeds $50.0 million, the Issuer will, within 30 days, make an offer to purchase to all Holders of such Notes (an “Asset Sale Offer”), and to all holders of other Debt containing provisions similar to those set forth in this Indenture with respect to assets sales (including, without limitation, the 2025 Notes), to purchase the maximum aggregate principal amount of such Notes and such other Debt that may be purchased out of the Excess Proceeds. The offer price for the Notes in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer in respect of such Notes, the Issuer may use those funds for any purpose not otherwise prohibited by this Indenture and they will no longer constitute Excess Proceeds. If the aggregate principal amount of Notes and other Debt tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Excess Proceeds will be allocated between such Notes and such other Debt based on the principal amount (or accreted value, if applicable) of such Notes and such other Debt tendered and the Trustee will select the Notes to be purchased on a pro rata basis among all such Notes tendered (subject to DTC procedures). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

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

Section 4.12 Effectiveness of Covenants.

(a) Following the first day (such date, the “Termination Date”):

(1) the Notes have a rating of Investment Grade from both S&P and Xxxxx’x and

(2) no Default has occurred and is continuing under this Indenture, the Issuer, the Parent and its Restricted Subsidiaries shall no longer be subject to the provisions of Sections 4.05, 4.06, 4.09 and 4.11.

(b) In the event that the Notes’ credit rating is downgraded from Investment Grade by any Rating Agency, the provisions of Sections 4.05, 4.06, 4.09 and 4.11 will not thereafter be reinstated.

(c) Promptly following the Termination Date, the Issuer shall provide an Officers’ Certificate to the Trustee regarding such occurrence. The Trustee shall have no obligation to independently determine or verify if a Termination Date has occurred or notify the Holders of the Termination Date. The Trustee may provide a copy of such Officers’ Certificate to any Holder upon request.

1.19 Article 11 “Guarantees” is hereby amended and restated in its entirety as follows:

ARTICLE 11

GUARANTEES

Section 11.01 Guarantee.

(a) Subject to this Article 11, each of the Parent and the Subsidiary Guarantors hereby, jointly and severally, irrevocably, fully and unconditionally guarantees, on a senior unsecured basis, to each Holder 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 Issuer hereunder or thereunder, that: (1) the principal, premium, if any, and interest on the Notes shall be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal and interest on the Notes, if any, if lawful, and all other obligations of the Issuer to the Holders or the Trustee hereunder or under the Notes shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same shall 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 (the obligations so guaranteed, collectively, the “Guaranteed Obligations”). Failing payment by the Issuer when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Parent and the Subsidiary Guarantors shall be jointly and severally obligated to pay the same immediately. Each of the Parent and Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Parent and the Subsidiary 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 with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. The Parent and each Subsidiary Guarantor hereby waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenants that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture, or pursuant to Section 11.06.

(c) Each of the Parent and the Subsidiary Guarantors also agrees, jointly and severally, to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) Incurred by the Trustee or any Holder in enforcing any rights under this Section 11.01.

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

(e) The Parent and each Subsidiary Guarantor agree that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations until payment in full of all Guaranteed Obligations. The Parent and each Subsidiary Guarantor further agree that, as between the Parent and the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the Guaranteed Obligations may be accelerated as provided in Article 6 for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations, and (2) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by the Parent and the Subsidiary Guarantors for the purpose of this Guarantee. The Parent and the Subsidiary Guarantors shall have the right to seek contribution from any non-paying Subsidiary Guarantor or Parent, as the case may be, so long as the exercise of such right does not impair the rights of the Holders under the Guarantees.

(f) Each Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuer for liquidation or reorganization, should the Issuer become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or the Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

(g) In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

(h) Each payment to be made by the Parent or a Subsidiary Guarantor in respect of its Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature.

Section 11.02 Limitation on Parent and Subsidiary Guarantor Liability.

Each Subsidiary Guarantor and the Parent, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Subsidiary Guarantor and the Parent not constitute a fraudulent conveyance or a fraudulent transfer 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 Guarantee. To effectuate the foregoing intention, the Trustee, the Holders, the Parent and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor and the Parent shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Subsidiary Guarantor or the Parent 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 Subsidiary Guarantor or the Parent in respect of the obligations of such other Subsidiary Guarantor or the Parent under this Article 11, result in the obligations of such Subsidiary Guarantor or the Parent under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law. Each Subsidiary Guarantor and the Parent that makes a payment under its Guarantee will be entitled upon payment in full of all Guaranteed Obligations under this Indenture to a contribution from each other Subsidiary Guarantor or the Parent, as the case may be, in an amount equal to such other Subsidiary Guarantor’s or the Parent’s pro rata portion of such payment based on the respective net assets of all the Subsidiary Guarantors and the Parent at the time of such payment, determined in accordance with GAAP.

Section 11.03 Execution and Delivery.

(a) To evidence its Guarantee set forth in Section 11.01, each Subsidiary Guarantor and the Parent hereby agree that this Indenture or a supplemental indenture to this Indenture shall be executed on behalf of such Subsidiary Guarantor and the Parent, as the case may be, by an Officer or person holding an equivalent title.

(b) Each Subsidiary Guarantor and the Parent hereby agree that its Guarantee set forth in Section 11.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes.

(c) If an Officer whose signature is on this Indenture or a supplemental indenture to this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Guarantees shall be valid nevertheless.

(d) The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors and the Parent, as the case may be.

Section 11.04 Subrogation.

Each Subsidiary Guarantor and the Parent shall be subrogated to all rights of Holders against the Issuer in respect of any amounts paid by any Subsidiary Guarantor or the Parent, as the case may be, pursuant to the provisions of Section 11.01; provided that, if an Event of Default has occurred and is continuing, no Subsidiary Guarantor or the Parent shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under this Indenture or the Notes shall have been paid in full.

Section 11.05 Benefits Acknowledged.

Each Subsidiary Guarantor and the Parent acknowledge that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the guarantee and waivers made by it pursuant to its Guarantee are knowingly made in contemplation of such benefits.
