written notice to the Indemnitee (the &#147;<U>Contest Notice&#148;</U>); <I>provided, however, </I>that if,
at the time a Notice of Claim is submitted to the Indemnifying Party the amount of the Loss

(the &#147;<U>Notice of Liability</U>&#148;) has been sent or delivered by the Indemnitee to the
Indemnifying Party setting forth the amount of the Loss incurred by the Indemnitee that was
the subject of the earlier Notice of Claim. Such Contest Notice shall specify the reasons
or bases for the objection of the Indemnifying Party to the claim, and if the objection
relates to the amount of the Loss asserted, the amount, if any, that the Indemnifying Party
believes is due the Indemnitee, and any undisputed amount shall be promptly paid over to the
Indemnitee. If no such Contest Notice is given within such twenty day period, the
obligation of the Indemnifying Party to pay the Indemnitee the amount of the Loss set forth

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) If there occurs an event that either party asserts is an indemnifiable event
pursuant to <U>Section&nbsp;7.1</U> or <U>7.2</U>, the party seeking indemnification (the
&#147;<U>Indemnitee</U>&#148;) shall promptly provide notice (the &#147;<U>Notice of Claim</U>&#148;) to the
other party or parties obligated to provide indemnification (the &#147;<U>Indemnifying
Party</U>&#148;). Providing the Notice of Claim shall be a condition precedent to any Liability
of the Indemnifying Party hereunder, and the failure to provide prompt notice as provided
herein will relieve the Indemnifying Party of its obligations hereunder but only if and to
the extent that such failure materially prejudices the Indemnifying Party hereunder. In
case any such action shall be brought against any Indemnitee and it shall provide a Notice
of Claim to the Indemnifying Party of the commencement thereof, the Indemnifying Party shall
be entitled to participate therein and, to the extent that it shall wish, to assume the
defense thereof, with counsel reasonably satisfactory to such Indemnitee and, after notice
from the Indemnifying Party to such Indemnitee of such election so to assume the defense
thereof, the Indemnifying
Party shall not be liable to the Indemnitee hereunder for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by the Indemnitee, in
connection with the defense thereof other than reasonable costs of investigation; <I>provided,
however</I>, that if the Indemnitee reasonably believes that counsel for the Indemnifying Party
cannot represent both the Indemnitee and the Indemnifying Party because such representation
would be reasonably likely to result in a conflict of interest, then the Indemnitee shall
have the right to defend, at the sole reasonable cost and expense of the Indemnifying Party,
such action by all appropriate proceedings. The Indemnitee agrees to reasonably cooperate
with the Indemnifying Party and its counsel in the defense against any such asserted
liability. In any event, the Indemnitee shall have the right to participate at its own
expense in the defense of such asserted liability. No Indemnifying Party, in the defense of
any such claim or litigation, shall, except with the written consent of each Indemnitee,
consent to entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the release of the Indemnitee from all Liability in respect to
such claim or litigation or that does not solely require the payment of money damages by the
Indemnifying Person. The Indemnifying Party agrees to afford the Indemnitee and its
counsel, at the Indemnitee&#146;s sole expense, the opportunity to be present at, and to
participate in, conferences with all Persons, including any Governmental Authority,
asserting any Claim against the Indemnitee or conferences with representatives of or counsel
for such Persons. In no event shall the Indemnifying Party, without the written consent of
the Indemnitee, settle any Claim on terms that provide for (i)&nbsp;a criminal sanction against
the Indemnitee or (ii)&nbsp;injunctive relief affecting the Indemnitee.

calendar days (or such shorter period as may be appropriate under the circumstances) to
contest its indemnification obligation with respect to such claim, or the amount thereof, by
written notice to the Indemnitee (the &#147;<U>Contest Notice&#148;</U>); <I>provided, however, </I>that if,
at the time a Notice of Claim is submitted to the Indemnifying Party the amount of the Loss
in respect thereof has not yet been determined, such twenty day period in respect of, but
only in respect of the amount of the Loss, shall not commence until a further written notice
(the &#147;<U>Notice of Liability</U>&#148;) has been sent or delivered by the Indemnitee to the
Indemnifying Party setting forth the amount of the Loss incurred by the Indemnitee that was
the subject of the earlier Notice of Claim. Such Contest Notice shall specify the reasons
or bases for the objection of the Indemnifying Party to the claim, and if the objection
relates to the amount of the Loss asserted, the amount, if any, that the Indemnifying Party
believes is due the Indemnitee, and any undisputed amount shall be promptly paid over to the
Indemnitee. If no such Contest Notice is given within such twenty day period, the
obligation of the Indemnifying Party to pay the Indemnitee the amount of the Loss set forth
in the Notice of Claim, or subsequent Notice of Liability, shall be deemed established and

assumed the defense and settlement of such Claim, fails reasonably to contest such Claim in
good faith, the Indemnitee, without waiving its right to indemnification, may assume, at the
reasonable cost of the Indemnifying Party, the defense and settlement of such Claim;
<I>provided, however, </I>that (i)&nbsp;the Indemnifying Party shall be permitted to
join in the defense and settlement of such Claim and to employ counsel at its own
expense, (ii)&nbsp;the Indemnifying Party shall cooperate with the Indemnitee in the defense and
settlement of such Claim in any manner reasonably requested by the Indemnitee and (iii)&nbsp;the
Indemnitee shall not settle such Claim without obtaining the prior written consent of the
Indemnifying Party, which shall not be unreasonably withheld or delayed.

under this Article that are not paid within five (5)&nbsp;Business Days of the date on which such
obligation becomes final shall thereafter be deemed delinquent, and the Indemnifying Party
shall pay to the Indemnitee, immediately upon demand, interest at the rate of ten percent
per annum, not to exceed the maximum nonusurious rate allowed by Applicable Law, from the
date such payment becomes delinquent to the date of payment of such delinquent sums, which
interest shall be considered to be Losses of the Indemnitee.
