under this Agreement shall be made as follows:
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;In the event a claim is made against an Indemnitee for which the Indemnitee would be
entitled to indemnification hereunder (a &#147;<U>Claim</U>&#148;), the Indemnitee shall notify the
Indemnitor of such Claim, specifying the nature and the amount of the Claim (the &#147;<U>Claim
Notice</U>&#148;). The Claim Notice must be delivered within &#091;. . . *** . . .&#093; after the Indemnitee
becomes aware of the Claim, provided that the failure of the Indemnitee to comply with such
requirement shall not relieve the Indemnitor of its obligations hereunder unless the Indemnitor is
materially prejudiced in the defense of the Claim due to such failure on the part of the
Indemnitee. The Indemnitor shall have the right to undertake and control the defense of any Claim
at its expense through counsel of its own choosing (subject to the Indemnitee&#146;s consent to such
counsel, which consent may not be unreasonably withheld or delayed). If the Indemnitor undertakes
the defense of a Claim: (i)&nbsp;the Indemnitor shall not permit to exist any lien, encumbrance or
other adverse charge upon any asset of the Indemnitee; (ii)&nbsp;the Indemnitor may not settle such
action without first obtaining the written consent of the Indemnitee, which consent will not be
unreasonably withheld or delayed, except for settlements solely covering monetary matters for which
the Indemnitor acknowledges responsibility for payment; and (iii)&nbsp;the Indemnitor shall permit the
Indemnitee (at the Indemnitee&#146;s sole cost and expense) to participate in such settlement or defense
through counsel chosen by the Indemnitee.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;The Indemnitee agrees to preserve and provide access to all evidence in its possession or
control that may be useful in defending against a Claim and to provide reasonable cooperation in
the defense thereof or in the prosecution of any action against a Third Party in connection
therewith at the Indemnitor&#146;s expense. The Indemnitor&#146;s defense of any Claim or demand shall not
constitute an admission or concession of liability therefor or otherwise operate in derogation of
any rights the Indemnitor may have against the Indemnitee or any third party. So long as the
Indemnitor is reasonably contesting any such Claim in good faith, the Indemnitee shall not pay or
settle any such Claim.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;If the Indemnitor elects not to undertake the defense of the Claim, the Indemnitee shall
have the right to assume the defense of the Claim through counsel of its own choosing and contest,
settle or compromise the Claim in the exercise of its exclusive discretion at the expense of the
Indemnitor. All reasonable expenses incurred by the Indemnitee pursuant to
