Section 5.11 Taxes. The Borrower and its Subsidiaries have filed all Federal, state and other material tax returns and reports required to be filed, and have paid all Federal, state and other material taxes, assessments, fees and other governmental charges levied or imposed upon them or their properties, income or assets otherwise due and payable, except those which are being contested in good faith by appropriate proceedings diligently conducted and for which adequate reserves have been provided in accordance with GAAP. Except as set forth on Schedule 5.11, there is no proposed tax assessment against the Borrower or any Subsidiary that could reasonably be expected to have a Material Adverse Effect. Neither any Loan Party nor any Subsidiary thereof is party to any tax sharing agreement.
