     SECTION 8.6  Limitations on Indemnification by the Company.
                  ---------------------------------------------
Notwithstanding the foregoing, the right of the Company Indemnified Parties to
indemnification under Section 8.5 shall be subject to the following provisions:

          (a)  no indemnification shall be payable pursuant to Section 8.5 above
to any Company Indemnified Party, unless the total of all claims for
indemnification pursuant to Section 8.5

                                       8

shall exceed $500,000 in the aggregate, whereupon the full amount of such claims

amount of damages which may be recovered by the Company Indemnified Parties from
the Company pursuant to Section 8.5 shall not exceed FIVE MILLION DOLLARS
($5,000,000).

     SECTION 8.7  Notice; Defense of Claims.  An indemnified party may make
                  -------------------------
claims for indemnification hereunder by giving written notice thereof to the
indemnifying party within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted (and in any event within 15 calendar days after the service of
the citation or sermons), but the failure to do so shall not relieve the
indemnifying party from any liability except to the extent that it is prejudiced
by the failure or delay in giving such notice. Such notice shall summarize the
bases for the claim for indemnification and any claim or liability being
asserted by a third party. Within 20 days after receiving such notice the
indemnifying party shall give written notice to the indemnified party stating
whether it disputes the claim for indemnification and whether it will defend
against any third party claim or liability at its own cost and expense. The
indemnifying party shall be entitled to direct the defense against a third party
claim or liability with counsel selected by it (subject to the consent of the
indemnified party, which consent shall not be unreasonably withheld) as long as
the indemnifying party is conducting a good faith and diligent defense. The
indemnified party shall at all times have the right to fully participate in the
defense of a third party claim or liability at its own expense directly or
through counsel; provided, however, that if the named parties to the action or
proceeding include both the indemnifying party and the indemnified party and the
indemnified party is advised in writing by the indemnifying party's counsel that
representation of both parties by the same counsel would be inappropriate under
applicable standards of professional conduct, the indemnified party may engage
separate counsel at the expense of the indemnifying party. If no such notice of
intent to dispute and defend a third party claim or liability is given by the
indemnifying party, or if such good faith and diligent defense is not being or
ceases to be conducted by the indemnifying party, the indemnified party shall
have the right, at the expense of the indemnifying party, to undertake the
defense of such claim or liability (with counsel selected by the indemnified
party), provided, however, that such claim or liability shall not be compromised
or settled without the written consent of the indemnifying party, which consent
shall not be unreasonably withheld. If the indemnified party settles or
compromises such claim or liability without the prior written consent of the
indemnifying party, the indemnifying party will bear no liability hereunder for
or with respect to such claim or liability. In the event the indemnified party
assumes the defense of the claim or liability, the indemnified party will keep
the indemnifying party reasonably informed of the progress of any such defense,
compromise or settlement. If the third party claim or liability is one that by
its nature cannot be defended solely by the indemnifying party, then the
indemnified party shall make available such information and assistance as the
indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense, at the expense of the indemnifying party.
