(a) Notice of Claim. If any legal proceeding shall be instituted, or any claim or demand made, against an indemnified party in respect of which an indemnifying party may be liable hereunder, or if either party hereto for any reason shall believe that it has a claim against the other pursuant to this Article 9, then the indemnified party or the party believing it has a claim against the other, as the case may be, (in either case, the "Indemnified Party") shall give prompt written notice hereunder to the indemnifying party or the party against whom the party giving notice believes it has a claim, as the case may be (in either case, the "Indemnifying Party"). Such notice shall specify in reasonable detail the date such underlying claim or belief first was asserted or arose, the nature of the loss(es) for which payment is claimed, the Section or Sections of this Agreement upon which such claim is based and the amount alleged to be payable in respect thereto. (b) Opportunity to Defend. If an Indemnifying Party shall receive notice pursuant to Section 9.3(a) hereof, the Indemnifying Party shall defend against the claims, liabilities and/or losses which are the subject of such notice. The Indemnified Party shall have the right to participate in such defense, trial counsel shall be chosen by the Indemnifying Party and such trial counsel shall be reasonably satisfactory to the Indemnified Party. If the Indemnifying Party provides notice to Indemnified Party that it shall defend such claim, then the Indemnified Party may do so by counsel of its choice, and the Indemnifying Party agrees to cooperate with the Indemnified Party in such defense.

In calculating the amount of the Indemnifying Party's indemnification obligation with respect to any Loss, due regard shall be given to any tax consequences of the Loss and any indemnification hereunder so that after indemnification the Indemnified Party shall, as nearly as possible, be in the same position (but no better than) that it would have been had the Loss not occurred. 9.4 Remedy. The parties' sole and exclusive remedy for Losses under this Agreement shall be those set forth in this Article 9.
