subsequently recovered from or repaid by the recipient thereof, in whole or in part, in any bankruptcy, reorganization, insolvency or similar proceedings instituted by or against Member, or otherwise, Guarantor’s obligations hereunder with respect to such Guaranteed Obligation shall be reinstated at such time to the same extent as though the payment or delivery so recovered or repaid had not been originally made.

5. Consents and Renewals.

7. Covenants and Agreements.

(a) Financial and Other Reporting. Throughout the Term of this Guaranty, Guarantor shall maintain a standard and modern system of accounting in accordance with GAAP and will furnish to Beneficiary and its duly authorized representatives such information respecting its business and financial condition as Beneficiary may reasonably request; and without any request, will furnish to Beneficiary:

(1) monthly, as soon as available and in any event within 45 days after the close of each calendar month, a copy of the consolidated and consolidating balance sheets of Guarantor as of the last day of such month and the consolidated statements of operations of Guarantor for the month and for the fiscal year to date period then ended, each in reasonable detail showing in comparative form the figures for the corresponding date and the period in the previous fiscal year prepared by Guarantor in accordance with GAAP and certified by the Chief Financial Officer of Guarantor or other officers of Guarantor acceptable to Beneficiary; provided, however, that if Guarantor does not in the ordinary course of business prepare any of such monthly financial statements in accordance with GAAP, such non-GAAP financial statements shall be accompanied with a brief explanation of any departures from GAAP;

(3) as soon as available and in any event within the applicable time period specified on Exhibit A hereto, the additional information regarding Guarantor described on Exhibit A hereto, which Beneficiary may update from time to time upon providing reasonable prior notice to Guarantor;

(4) promptly after knowledge thereof shall have come to the attention of any responsible officer of Guarantor, written notice of (i) any threatened or pending litigation or governmental proceeding which, if adversely determined, would cause a Material Adverse Event with respect to Guarantor, Member or any Affiliate Pledgor, and (ii) the occurrence of any event that would have the effect of rendering as untrue any of the representations and warranties contained in Section 6 of this Guaranty;

(5) promptly after receipt thereof, any written reports, management letters or other detailed information contained in writing concerning significant aspects of Guarantor’s operations and financial affairs given to it by its independent public accountants;

(6) immediately upon receipt thereof, copies of interim and supplemental reports if any, submitted to Guarantor by independent accountants in connection with any interim audit or review of the books of Guarantor; and

In addition to the information to be provided by Guarantor under Section 7(a) above, Guarantor shall provide prompt written notice to Beneficiary of any payment default by Guarantor under any other note, indenture, undertaking or agreement for the borrowing of money by Guarantor, to the extent that such default has not been cured by Guarantor, or waived by such creditor, within ten (10) business days of the occurrence of such default.

8. Subrogation. Guarantor will not exercise any rights that it may acquire by way of subrogation until all of the Guaranteed Obligations to Beneficiary have been paid in full. If any amount is paid to Guarantor in violation of the preceding sentence, such amount shall be held for the benefit of Beneficiary and shall then be paid to Beneficiary to be credited and applied to the Guaranteed Obligations, whether matured or unmatured. Subject to the foregoing, upon payment of all the Guaranteed Obligations, Guarantor shall be subrogated to the rights of Beneficiary against Member and Beneficiary agrees to take at Guarantor’s expense such steps as Guarantor may reasonably request to implement such subrogation.

9. No Set-off or Counterclaim by Guarantor; Taxes. All payments and deliveries under this Guaranty shall be made by Guarantor in U.S. Dollars and without set-off, counterclaim or deduction or withholding for any tax. If Guarantor is required by law to deduct or withhold any taxes, Guarantor shall pay to Beneficiary such additional amounts as necessary to ensure that the amount received by Beneficiary equals the full amount Beneficiary would have received had no such deduction or withholding been required. Guarantor agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, 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 Guaranteed Obligations.

11. Cumulative Rights. No failure on the part of Beneficiary to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Beneficiary of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to Beneficiary or allowed it by law or other agreement shall be cumulative and not exclusive of any other, and may be exercised by Beneficiary from time to time.

12. Governing Law; Submission to Jurisdiction.
