SECTION 1. Defined Terms. Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement.

SECTION 2. Amendments to Section 6.03 of the Credit Agreement. Section 6.03 of the Credit Agreement is hereby amended in its entirety to read as follows:

Section 6.03. Fundamental Changes.

(a) Mergers, Sales of Assets, Etc. The Borrower will not, and will not permit any Restricted Subsidiary to, merge into or consolidate with any other Person, or permit any other Person to merge into or consolidate with it, or sell, transfer, lease or otherwise dispose of (in one transaction or in a series of transactions) all or substantially all of its assets, or all or substantially all of the stock of any of its Restricted Subsidiaries (in each case, whether now owned or hereafter acquired), or liquidate or dissolve, except that, if at the time thereof and immediately after giving effect thereto no Default or Event of Default shall have occurred and be continuing:

(i) any Restricted Subsidiary may merge into the Borrower in a transaction in which the Borrower is the surviving corporation,

(ii) any Subsidiary may merge into any Restricted Subsidiary in a transaction in which the surviving entity is a Restricted Subsidiary; provided that if any such transaction shall be between a Subsidiary Guarantor and a Restricted Subsidiary not a Subsidiary Guarantor, and such Subsidiary Guarantor is not the continuing or surviving corporation, then the continuing or surviving corporation shall have assumed all of the obligations of such Subsidiary Guarantor hereunder and under the other Loan Documents pursuant to documentation satisfactory to the Administrative Agent in form and substance,

(iii) any Restricted Subsidiary may sell, transfer, lease or otherwise dispose of its assets to the Borrower or to another Restricted Subsidiary; provided that if any such transaction shall be between a Subsidiary Guarantor and a Restricted Subsidiary not a Subsidiary Guarantor, and if such Subsidiary Guarantor is not the continuing or surviving corporation, then the continuing or surviving corporation shall have assumed all of the obligations of such Subsidiary Guarantor hereunder and under the other Loan Documents pursuant to documentation satisfactory to the Administrative Agent in form and substance,

(iv) any Restricted Subsidiary may liquidate or dissolve if the Borrower determines in good faith that such liquidation or dissolution is in the best interests of the Borrower and is not materially disadvantageous to the Lenders,

(v) prior to the Security Termination Date, the stock or assets of any Restricted Subsidiary may be sold, transferred, leased or otherwise disposed of in connection with the making of an investment in a Joint Venture permitted under Section 6.04(h)(iii) below, and

(vi) the stock or assets of any Restricted Subsidiary may be sold, transferred, leased or otherwise disposed of in a transaction permitted under Section 6.10;

provided that any such merger that would otherwise be permitted by this Section 6.03 involving a Person that is not a wholly owned Restricted Subsidiary immediately prior to such merger shall not be permitted unless also permitted by Section 6.04.

(b) Lines of Business. The Borrower will not, and will not permit any of its Restricted Subsidiaries to, engage to any material extent in any business other than businesses of the type conducted by the Borrower and its Subsidiaries on the Effective Date and businesses reasonably related thereto.

2

(c) Sales of Assets. On and after the Security Termination Date, the Borrower will not, and will not permit any of its Restricted Subsidiaries to, sell, transfer, lease or otherwise dispose of (in one transaction or in a series of transactions) any of its assets or property, whether now owned or hereafter acquired, or, in the case of any Restricted Subsidiary, issue or sell any shares of such Restricted Subsidiary’s capital stock to any Person, except:

(i) the sale, transfer or other disposition of obsolete, worn out or surplus property in the ordinary course of business;

(ii) the sale of inventory and goods held for sale in the ordinary course of business;

(d) Notwithstanding the restrictions set forth in this Section 6.03, (i) the divestiture or other disposition of specific assets and property of the Borrower or its Restricted Subsidiaries pursuant to an order by any Governmental Authority shall be permitted to the extent such order is given by such Governmental Authority as a prerequisite to the receipt of such Governmental Authority’s approval in connection with a pending Acquisition by the Borrower or any Restricted Subsidiary and the Borrower or such Restricted Subsidiary shall have repaid all Indebtedness (other than Indebtedness outstanding hereunder) associated with the assets or property so divested or disposed (or such Indebtedness shall have been assumed by the purchaser of such assets or property) and (ii) the sale, transfer or other disposition of other property or assets of the Borrower and the Restricted Subsidiaries (including the sale of stock or other assets otherwise prohibited by Sections 6.03(a) or (c)) for fair value shall be permitted so long as (A) the aggregate amount of all such sales, transfers and other dispositions by the Borrower and the Restricted Subsidiaries, taken as a

3

whole, pursuant to this Section 6.03(d)(ii), shall not exceed, in the aggregate, 20% of the Consolidated Total Assets; provided that, to the extent that (1) the proceeds of any such sale, transfer or other disposition permitted under this Section 6.03(d)(ii)(A) are reinvested in assets that are related to the business in which the Borrower and its Restricted Subsidiaries are permitted to be engaged under Section 6.03(b) within the period of twelve (12) months following such sale, transfer or other disposition and (2) the amount of proceeds of all such sales, transfers or other dispositions that are subject to reinvestment do not at any one time exceed 20% of the Consolidated Total Assets, such sale, transfer or other disposition shall be excluded for purposes of computing the amount of sales, transfers and other dispositions made pursuant to Section 6.03(d)(ii)(A); provided, further, that, to the extent that the Borrower or any Restricted Subsidiary has acquired any assets that are related to the business in which the Borrower and its Restricted Subsidiaries are permitted to be engaged under Section 6.03(b) during the period six months prior to such sale, transfer or other disposition, then the proceeds of such sale, transfer or other disposition may be deemed to have been reinvested for the purpose of determining compliance with the preceding proviso and (B) at the time thereof and immediately after giving effect thereto, no Default or Event of Default shall have occurred and be continuing;

SECTION 3. Conditions to Effectiveness. This Amendment shall become effective upon the date (the “First Amendment Effective Date”) on which the Administrative Agent shall have received counterparts of this Amendment, executed and delivered by a duly authorized officer of each of the Obligors and Lenders constituting the Required Lenders.

The Borrower represents and warrants to the Administrative Agent and the Lenders that as of the First Amendment Effective Date, after giving effect to this Amendment, no Default or Event of Default has occurred and is continuing and the representations and warranties made by the Borrower in or pursuant to the Credit Agreement or any other Loan Document are true and correct in all material respects on and as of the First Amendment Effective Date as if made on such date (except to the extent that any such representations and warranties expressly relate to an earlier date, in which case such representations and warranties were true and correct in all material respects on and as of such earlier date).

SECTION 5. Effect of Amendment. (a) This Amendment shall not constitute an amendment or waiver of or consent to any provision of the Credit Agreement and the other Loan Documents not expressly referred to herein and shall not be construed as an amendment, waiver or consent to any action on the part of the Borrower that would require an amendment, waiver or consent of the Administrative Agent or the Lenders except as expressly stated herein. Except as expressly amended hereby, the provisions of the Credit Agreement and the other Loan Documents are and shall remain in full force and effect in accordance with its terms.
