Promptly after receipt by an indemnified party under this Section 1.6 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided , however , that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if (1) the indemnifying party has agreed in writing to pay such fees and expenses; and (2) the indemnifying party shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such indemnified party in any such proceeding; or (3) representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.6.
