Each Group Member has timely filed or caused to be filed all federal and other material Tax returns and reports required to have been filed by it and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which adequate reserves have been set aside in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Group Members in respect of Taxes and other governmental charges are, in the reasonable opinion of the Borrower, adequate. No Tax Lien has been filed and, to the knowledge of the Borrower, no claim is being asserted with respect to any material Tax of any Group Member, in each case, that could not reasonably be expected to result in a Material Adverse Effect.
