Federal Reserve Regulations; Use of Proceeds
The Borrower is not engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System, as amended. No part of the proceeds of the Loans or the Letters of Credit has been or will be used, directly or indirectly, and whether immediately, incidentally or ultimately, for a purpose which violates any law, rule or regulation of any Governmental Authority, including, without limitation, the provisions of Regulations T, U or X of the Board of Governors of the Federal Reserve System, as amended. Anything in this Agreement to the contrary notwithstanding, neither the Issuer nor any Lender shall be obligated to extend credit to or on behalf of the Borrower in violation of any limitation or prohibition provided by any applicable law, regulation or statute, including said Regulation U. Following application of the proceeds of each Loan and the issuance of each Letter of Credit, not more than 25% (or such greater or lesser percentage as is provided in the exclusions from the definition of “Indirectly Secured” contained in said Regulation U as in effect at the time of the making of such Loan or issuance of such Letter of Credit) of the value of the assets of the Borrower and the Subsidiaries on a Consolidated basis that are subject to Section 8.2 will be Margin Stock. In addition, no part of the proceeds of any Loan or Letter of Credit will be used, whether directly or indirectly, and whether immediately, incidentally or ultimately, to make a loan to any director or executive officer of the Borrower or any Subsidiary.
