Each of the Parent Guarantor and its Subsidiaries is in compliance with all applicable Law, including, without limitation, all Environmental Laws, except where any failure to comply with any such laws would not, alone or in the aggregate, have a Material Adverse Effect on the business or financial condition of the Parent Guarantor and its Subsidiaries taken as a whole, or the Parent Guarantor's ability to perform its obligations under the Loan Documents. (r) Trademarks, Copyrights, Etc. The Parent Guarantor and each of its Subsidiaries own or have the rights to use such trademarks, service marks, trade names, copyrights, patents, licenses or rights in any thereof, as in the aggregate are adequate in the reasonable judgment of the Parent Guarantor for the conduct of the business of the Parent Guarantor and its Subsidiaries as now conducted. (s) Year 2000 Issue.

The Year 2000 Problem will not result in a Material Adverse Effect. (t) Pari Passu Obligations. The obligations of the Parent Guarantor under this Guaranty do rank at least pari passu in priority of payment with all other present unsecured Indebtedness of the Parent Guarantor. (u) Investment Company Act. It is not an "investment company" or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company," as such terms are defined in the Investment Company Act of 1940, as amended. The making of the Loans by the Banks, the application of the proceeds and repayment thereof and the consummation of the transactions contemplated by the Credit Agreement will not violate any provision of such act or any rule, regulation or order issued by the Securities and Exchange Commission thereunder.

All filing fees and other expenses in connection with each such action have been or will be paid by the Borrower. (w) Corporate Headquarters.

(b) No Reductions.

(ii) (x) If any withholding or deduction from any payment to be made by the Parent Guarantor hereunder is required for any Taxes under any applicable law, rule or regulation, then the Parent Guarantor will: (A) pay directly to the relevant taxing authority the full amount required to be so withheld or deducted; (B) promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent evidencing such payment to such authority; and (C) pay to the Administrative Agent for the account of the Banks such additional amount or amounts necessary to ensure that the net amount actually received by each Bank will equal the full amount such Bank would have received had no such withholding or deduction been required. In addition, to the extent permitted by applicable law, the Parent Guarantor agrees to pay any present or future stamp or documentary taxes, excise or property taxes, or any other charges or similar levies which arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Guaranty or the Notes (hereinafter referred to as "Other Taxes"). Each Bank shall use its reasonable best efforts to designate another of its then existing offices as its Lending Office if the making of such designation would, without any detrimental effect to such Bank (as determined by the Bank in its sole discretion), avoid the need for, or reduce the amount of, such withholding or deduction from any payment to be made to such Bank by the Parent Guarantor hereunder required for any Taxes. The Parent Guarantor will indemnify each Bank and the Administrative Agent for the full amount of Taxes or Other Taxes paid by such Bank or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This Indemnification shall be made within 30 days from the date such Bank or the Administrative Agent (as the case may be) makes written demand therefor.

(y) Notwithstanding subsection (x), the Parent Guarantor shall not be required to indemnify or pay additional amounts for or on account of: (A) Taxes imposed on or measured by the net income of the Administrative Agent or any Bank or franchise Taxes imposed on the Administrative Agent or any Bank, but in each case only to the extent imposed by the jurisdiction under the laws of which the Administrative Agent or such Bank is organized or doing business (other than as a result of the transactions contemplated by the Loan Documents or the Administrative Agent's or any Bank's enforcement of its rights under any Loan Document) or any political subdivision or taxing authority thereof or therein, or by any jurisdiction in which the Administrative Agent or such Bank's Lending Office or principal executive office is located or any political subdivision or taxing authority thereof or therein (except, in each case, to the extent required by the following paragraph to make payments on an after-tax-basis), or (B) any Tax or Other Tax imposed by reason of either (i) the failure of the certification made by a Bank on any form provided pursuant to Section 9(b)(iii) to be accurate and true in all material respects unless any such failure is attributable solely to a Change in Tax Law that occurs on or after the date on which such form is provided by such Bank, or (ii) the failure by a Bank to deliver to the Parent Guarantor (or the Borrower) and the Administrative Agent two duly completed and executed copies of IRS Form 1001 or 4224 (or successor applicable forms) in accordance with the second sentence of Section 9(b)(iii), certifying that such Bank is entitled to receive payments under this Guaranty and the Loans without deduction or withholding of any United States federal income taxes, provided that this clause (B)(ii) will not apply if such failure is attributable solely to a Change in Tax Law that occurs on or after the date hereof. All amounts payable as additional amounts or indemnities pursuant to this Section 9(b) shall include an amount necessary to hold the Administrative Agent or the relevant Bank harmless on a net after-tax-basis from and against all Taxes required to be paid with respect to or as a result of the payment of such additional amount or indemnity (including, without limitation, Taxes described in clause (A) of the preceding paragraph.) (iii) Each Bank that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) agrees that it will, on or before the date that the Parent Guarantor delivers this Guaranty, deliver to the Parent Guarantor and the Administrative Agent two duly completed and executed copies of IRS Form 1001 or 4224 or successor applicable form, as the case may be, certifying in each case that such Bank is entitled to receive payments payable to it under this Guaranty, and the Loans without deduction or withholding of any United States federal income taxes. Each Bank that undertakes to deliver to the Parent Guarantor and the Administrative Agent an IRS Form 1001 or 4224 under the preceding sentence further undertakes to deliver to the Administrative Agent and the Parent Guarantor two additional duly completed and executed copies of Form 1001 or 4224 (or successor applicable forms) on or before the date that any such form expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Parent Guarantor and the Administrative Agent, and such extensions or renewals thereof as may reasonably be required by the Parent Guarantor, certifying, in the case of a Form 1001 or 4224, that such Bank is entitled to receive payments under this Guaranty and the Loans without deduction or withholding of any United States federal income taxes, unless, in any such case, an event (including, without limitation, any Change in Tax Law) has occurred before the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which causes such Bank to be no longer eligible to complete and deliver any such form with respect to it, in which case the Bank shall either (I) furnish to the Parent Guarantor such forms or other certification as the Bank (in its sole opinion) is legally entitled to furnish evidencing the Bank's eligibility for a complete exemption from or a reduced rate of withholding of United States federal income taxes, or (2) notify the Parent Guarantor that the Bank is not capable of receiving payments without any deduction or withholding of United States federal income tax.

The remedies herein provided are cumulative and not exclusive of any remedies provided by law. SECTION 12 Right of Set-off. Upon the occurrence and during the continuance of any Event of Default (as defined in the Credit Agreement), each Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Bank to or for the credit or the account of the Parent Guarantor against any and all of the obligations of the Parent Guarantor now or hereafter existing under this Guaranty, irrespective of whether or not such Bank shall have made any demand under this Guaranty. Each Bank agrees promptly to notify the Parent Guarantor after any such set-off and application made by such Bank; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application.
