Each of the Loan Parties will, and will cause its Restricted Subsidiaries to, pay and discharge all material Taxes imposed upon it or upon its income or profits, or upon any properties or assets belonging to it, and all material fees or other charges for all lawful claims which, if unpaid, could be reasonably expected to become a Lien (other than Permitted Liens) upon the property of any of the Loan Parties or any of their Restricted Subsidiaries, provided that none of the Loan Parties or their Restricted Subsidiaries shall be required to pay any such Tax, fee or other claim as to which the such Loan Party or Restricted Subsidiary has a good faith basis to believe is not due and owing and, to the extent then appropriate, the payment thereof is being contested in good faith and by proper proceedings, provided that such Loan Party or Restricted Subsidiary maintains adequate reserves in accordance with GAAP with respect thereto.
