On the Sixth Amendment Effective Date (as defined below), Section 4.04(b) of the Credit Agreement is hereby amended by deleting such Section in its entirety and inserting in lieu thereof the following new Section: "(b) Each Bank that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) agrees to deliver to the Company and the Administrative Agent promptly after the Sixth Amendment Effective Date, or in the case of a Bank that is an assignee or transferee of an interest under this Agreement pursuant to Section 13.04 (unless the respective Bank was already a Bank hereunder immediately prior to such assignment or transfer), on the date of such assignment or transfer to such Bank, (i) two accurate and complete original signed copies of Internal Revenue Service Form 4224 or 1001 (or successor forms) certifying to such Bank's entitlement to a complete exemption from United States withholding tax with respect to payments to be made under this Agreement and under any Note, or (ii) if the Bank is not a "bank" within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue Service Form 1001 or 4224 pursuant to clause (i) above, (x) a certificate substantially in the form of Exhibit A hereto (any such certificate, a "Section 4.04(b)(ii) Certificate") and (y) two accurate and complete original signed copies of Internal Revenue Service Form W-8 (or successor form) certifying to such Bank's entitlement to a complete exemption from United States withholding tax with respect to payments of interest to be made under this Agreement and under any Note; provided, however, that any Bank which has previously delivered such forms which would otherwise satisfy the requirements of this sentence shall hereafter be deemed to have complied with the requirements of this sentence. In addition, each Bank agrees that from time to time after the Sixth Amendment Effective Date, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to the Company and the Administrative Agent two new accurate and complete original signed copies of Internal Revenue Service Form 4224 or 1001, or Form W-8 and a Section 4.04(b)(ii) Certificate, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Bank to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement and any Note, or it shall immediately notify the Company and the Administrative Agent of its inability to deliver any such Form or Certificate. Notwithstanding anything to the contrary contained in Section 4.04(a) (x) any Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Bank which is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent that such Bank has not provided to the Company and Administrative Agent U.S. Internal Revenue Service Forms that establish a complete exemption from such deduction or withholding and (y) no Borrower shall be obligated pursuant to Section 4.04(a) hereof to gross-up payments to be made to a Bank in respect of income or similar taxes imposed by the United States if such Bank has not provided to the Company and the Administrative Agent the Internal Revenue Service Forms required to be provided to the Company and the Administrative Agent pursuant to this Section 4.04(b) or to the extent that such Forms do not establish a complete exemption from withholding of such taxes." 2. On the Sixth Amendment Effective Date, Section 13.04(b) of the Credit Agreement is hereby amended by inserting at the end of the first sentence thereof the following new proviso: "and, provided further, that no such transfer or assignment by a Specified Bank will be effective until recorded by the Administrative Agent on the Register pursuant to Section 13.04(d) hereof." 3. On the Sixth Amendment Effective Date, Section 13.04(d) of the Credit Agreement is hereby amended by inserting the following at the end thereof: "With respect to any Specified Bank, the Administrative Agent shall maintain the Register, solely for purposes of this Section 13.04(d), as an agent of each Borrower. The transfer of the Commitments and Loans of any Specified Bank and the rights to the principal of, and interest on, any Loans or any Loans made pursuant to such Commitments shall not be effective until such transfer is recorded in the Register maintained by the Administrative Agent with respect to ownership of such Commitments and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitments and Loans shall remain owing to the transferor. The registration of an assignment or transfer by a Specified Bank of all or part of its Commitments and Loans shall be recorded by the Administrative Agent on the Register only upon the acceptance by the Administrative Agent of a properly executed and delivered Assignment and Acceptance pursuant to Section 13.04(b). Coincident with the delivery by a Specified Bank of such Assignment and Acceptance to the Administrative Agent for acceptance and registration of an assignment or transfer of all or part of a Loan, or as soon thereafter as practicable, the assigning or transferor Specified Bank shall surrender the Registered Note evidencing such Loan, and thereupon one or more new Registered Notes in the same aggregate principal amount shall be issued to the assigning or transferor Specified Bank and/or the new Bank. The Administrative Agent shall indemnify and defend the Borrowers for and against any and all actions, claims, costs and damages which arise from or out of the agency relationship established by this Section 13.04(d) other than any actions, claims, costs and damages which result primarily from the gross negligence or willful misconduct of the Borrowers. Subject to Section 11.02, neither the Administrative Agent nor the Borrower shall be liable in any respect to the Banks in connection with the maintenance of the transfer and registration system pursuant to this Section 13.04(d)." 4. On the Sixth Amendment Effective Date Section 13.04(e) of the Credit Agreement is hereby amended by inserting at the end thereof the following: "Each Bank that has executed and delivered the Sixth Amendment and that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) and that could become completely exempt from withholding of any tax, assessment or other charge or levy imposed by or on behalf of the United States of America or any taxing authority thereof in respect of payment of Obligations due to such Bank if the Obligations were in registered form for U.S. Federal income tax purposes may request the Company (through the Administrative Agent), and the Company thereby agrees, upon such Bank's satisfaction of the requirements of Sections 4.04(b), to record such Obligations in the Register and exchange any Notes evidencing such Obligations for Notes in registered form ("Registered Notes") for U.S. Federal income tax purposes (which form shall be in substantially the form of Exhibit B-1, B-2, B-3, B-4, B-5, B-6, B-7, B-8, B-9, B-10, or B-11, as the case may be, except that such Registered Notes shall be made payable to such Bank or its registered assigns). Registered Notes shall be deemed to be and shall be Notes for all purposes of the Credit Agreement and the other Credit Documents. Any Bank that makes a request pursuant to the second immediately preceding sentence and receives Registered Notes in exchange for its Notes, together with any subsequent transferee or assignee of such Bank, is hereinafter called a "Specified Bank." Registered Notes may not be exchanged for Notes that are not in registered form." 5. On the Sixth Amendment Effective Date, Section 10 of the Credit Agreement is hereby amended by inserting therein the following new defined terms in the appropriate alphabetical order: "Registered Notes" shall have the meaning provided in Section 13.04(e). "Sixth Amendment Effective Date" shall have the meaning provided in the Sixth Amendment to the Credit Agreement dated as of August 16, 1994." "Specified Bank" shall have the meaning provided in Section 13.04(e). 6. On the Sixth Amendment Effective Date, Exhibit G to the Credit Agreement is hereby amended by adding immediately following Section 7 thereof the following new Section 8: "8. Notwithstanding anything to the contrary contained herein, this Assignment and Acceptance Agreement shall not be effective until the assignment effected hereby is recorded by the Administrative Agent on the Register pursuant to Section 13.04(d) of the Credit Agreement. By its execution and delivery hereof, the Assignee hereby expressly agrees to the terms of the Sixth Amendment to the Credit Agreement." 7. In order to induce the Banks to enter into this Amendment, each of the Credit Parties (other than the ESOP Trustee) hereby (a) certifies that no Default or Event of Default exists and that each of the representations, warranties and agreements contained in Section 6 of the Credit Agreement on the Sixth Amendment Effective Date, both before and after giving effect to this Amendment, is true and correct in all material respects and (b) confirms that it has and will continue to comply with all of its obligations contained in the Credit Agreement and the other Credit Documents including with respect to each of the Borrowers, but not limited to, all of its obligations contained in Section 7.10(b) of the Credit Agreement. 8. This Amendment is limited as specified and shall not constitute a modification, acceptance or waiver of any other provision of the Credit Agreement or any other Credit Document. 9. This Amendment may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which counterparts when executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. A complete set of counterparts shall be lodged with the Company and the Administrative Agent. 10. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK. 11. This Amendment shall become effective on the date (the "Sixth Amendment Effective Date") when the Company, the Subsidiary Borrowers, the ESOP Trustee, the Administrative Agent, the Co-Agents and the Required Banks shall have signed a copy hereof (whether the same or different copies) and shall have delivered (including by way of telecopier) such copies to the Administrative Agent. 12. From and after the Sixth Amendment Effective Date, all references in the Credit Agreement and each of the Credit Documents or any other agreement to the Credit Agreement shall be deemed to be references to such Credit Agreement as amended hereby. IN WITNESS WHEREOF, each of the parties hereto has caused a counterpart of this Amendment to be duly executed and delivered as of the date first above written.
