Debtor has filed or caused to be filed all tax returns required to be filed and has paid, or has made adequate provisions for the payment of, all taxes shown to be due and payable on said returns or in any assessments made against it (other than those being contested in good faith by appropriate proceedings and with respect to which adequate reserves have been set aside on its books) which would be material to Debtor, and no undischarged tax liens have been filed with respect thereto. The charges, accruals and reserves on the books of Debtor with respect all taxes are adequate for the payment of such taxes, and Debtor knows of no material unpaid assessment which is due and payable against Debtor except such thereof as are being contested in good faith by appropriate proceedings and for which adequate reserves have been set aside.
