(f) INDEMNIFICATION PROCEDURES. (1) If a claim shall be made by any taxing authority that, if successful, would result in the indemnification of a party under this Agreement (referred to herein as the "Tax Indemnified Party"), the Tax Indemnified Party shall promptly notify the party obligated under this Agreement to so indemnify (referred to herein as the "Tax Indemnifying Party") in writing; provided, however, that no delay on the part of the Tax Indemnified Party in notifying the Tax Indemnifying Party shall relieve the Tax Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Tax Indemnifying Party is prejudiced thereby. (2) The Tax Indemnified Party shall take such action in connection with contesting such claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including the selection of counsel and experts and the execution of powers of attorney, provided that (A) within 30 days after the notice described in Section 8(f)(1) has been delivered (or such earlier date that any payment of Taxes is due by the Tax Indemnified Party but in no event sooner than 5 days after the Tax Indemnifying Party's receipt of such notice), the Tax Indemnifying Party requests that such claim be contested, (B) the Tax Indemnifying Party shall have agreed to pay to the Tax Indemnified Party all costs and expenses that the Tax Indemnified Party incurs in connection with contesting such claim, including, without limitation, reasonable attorneys' and accountants' fees and disbursements, and (C) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax claimed and sue for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such claim.

(3) Subject to the provisions of Section 8(f)(2), the Tax Indemnified Party shall enter into a settlement of such contest with the applicable taxing authority or prosecute such contest to a determination in a court or other tribunal of initial or appellate jurisdiction, all as the Tax Indemnifying Party may request. (4) If, after actual receipt by the Tax Indemnified Party of an amount advanced by the Tax Indemnifying Party pursuant to Section 8(f)(2)(C), the extent of the liability of the Tax Indemnified Party with respect to the claim shall be established by the final judgment or decree of a court or other tribunal or a final and binding settlement with an administrative agency having jurisdiction thereof, the Tax Indemnified Party shall promptly repay to the Tax Indemnifying Party the amount advanced to the extent of any refund received by the Tax Indemnified Party with respect to the claim together with any interest received thereon from the applicable taxing authority and any recovery of legal fees from such taxing authority, net of any Taxes as are required to be paid by the Tax Indemnified Party with respect to such refund, interest or legal fees (calculated at the maximum applicable statutory rate of Tax without regard to any other Tax Items). Notwithstanding the foregoing, the Tax Indemnified Party shall not be required to make any -32- 13 payment hereunder before such time as the Tax Indemnifying Party shall have made all payments or indemnities then due with respect to the Tax Indemnified Party pursuant to this Agreement.
