threatened to be involved, as a party or otherwise,  by reason of its management
of the affairs of the  Company or which  relates to or arises out of the Company
or its property,  business or affairs. A Covered Person shall not be entitled to
indemnification  under  this  Section  10.2 with  respect  to (i) any Claim with
respect to which such Covered Person has engaged in fraud,  willful  misconduct,
bad faith or gross negligence or (ii) any Claim initiated by such Covered Person
unless  such Claim (or part  thereof)  (A) was brought to enforce  such  Covered
Person's rights to indemnification  hereunder or (B) was authorized or consented
to by the Board prior to its initiation by the Covered Person. Expenses incurred
by a Covered  Person in  defending  any Claim shall be paid by the Company  upon
presentation  to the  Company  of  satisfactory  documentation  evidencing  such
expenses and in advance of the final  disposition  of such Claim upon receipt by
the Company of an  undertaking  by or on behalf of such Covered  Person to repay
any amounts advanced by the Company promptly, in full, if it shall be ultimately

restrict,  alter or otherwise adversely affect any other right to exculpation or
to  indemnification or any other right or remedy available to any Covered Person
under this Agreement, any other agreement, any vote of the Board, any applicable
law or otherwise, both with respect to acts or omissions in an official capacity
and acts or  omissions  in a  separate  capacity  while  holding  such  official
capacity.

     10.4 Additional Covered Persons.  The Board or a duly authorized  committee
thereof may, in its sole and absolute  discretion,  provide the rights set forth
in this Article 10 to any employee, representative, consultant, advisor or agent
of the  Company  and in such case,  such  persons  shall have all the rights and
entitlements  of a Covered Person as of the date  determined by the Board in its
sole and absolute discretion.

modification  with  respect  to any acts or  omissions  occurring  prior to such
