The indemnified party shall furnish to the indemnifying party in reasonable detail such information as the indemnified party may have with respect to such indemnification claims (including copies of any summons, complaint or other pleading which may have been served on it and any written claim, demand, invoice, billing or other document evidencing or assenting the same). Subject to the limitations set forth in Section 4.4, no failure or delay by the indemnified party in the performance of the foregoing shall reduce or otherwise affect the obligation of the indemnifying party to indemnify and hold the indemnified party harmless except to the extent that such failure or delay shall have materially and adversely affected the indemnifying party's ability to defend against, settle or satisfy any action, suit or proceeding the claim for which the indemnified party is entitled to indemnification hereunder. (b) If the claim or demand set forth in the Notice of Claim given by the indemnified party is a claim or demand asserted by a third party, the indemnifying party has thirty (30) days after the Date of Notice of Claim to notify the indemnified party in writing of its election to defend such third party claim or demand on behalf of the indemnified party (the "Notice Period "); provided, however, that the indemnified party is authorized to file any motion, answer or other pleading which it deems necessary or appropriate to protect its interests during the Notice Period.

The indemnified party has the right to employ counsel separate from counsel employed by the indemnifying party in any such action and to participate therein, but the fees and expenses of such counsel will be at the indemnified party's own expense, unless (a) the employment thereof has been specifically authorized by the indemnifying party, (b) such indemnified party will have been advised by counsel reasonably satisfactory to the indemnifying party that there may be one or more legal defenses available to it that are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such Indemnified Party to employ separate counsel, or (c) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case the fees will be paid by the indemnifying party. If the indemnifying party assumed the defense of any claim or proceeding in accordance with this Section 4.6, the indemnifying party will be authorized to consent to a settlement of, or the entry of any judgment arising from, any such claim or proceeding, with the prior written consent of such indemnified party, not to be unreasonably withheld; provided, however, that the indemnifying party is not authorized to encumber any of the assets of any indemnified party or to agree to any restriction that would apply to any indemnified party or to its conduct of business; and provided further, that a condition to any such settlement is a complete release of such indemnified party and its affiliates, directors, officers, employees and agents with respect to such claim, including any reasonably foreseeable collateral consequences thereof. If the indemnifying party does not elect to defend such third party claim or demand or does not defend such third party claim or demand in good faith, the indemnified party shall have the right, in addition to any other right or remedy it may have hereunder at the indemnifying party's expense, to defend such third party claim or demand.
