generality of the foregoing, Lenders' Representative,  on behalf of the Lenders,
without   demand  of  performance   or  other  demand,   presentment,   protest,

to below) to or upon Grantor or any other person (all and each of which demands,

other  disposition of Collateral  shall be required by law, such notice shall be
deemed reasonable and proper if given at least 10 days before such sale or other

or agents shall be liable for failure to demand,  collect or realize upon all or
any part of the  Collateral  or for any  delay in doing so or shall be under any

coupled with an interest.

      11.  Severability.  Any  provision  of this  Security  Agreement  which is
prohibited or unenforceable in any jurisdiction  shall, as to such jurisdiction,
be ineffective to the extent of such  prohibition  or  unenforceability  without
invalidating  the  remaining  provisions  hereof,  and any such  prohibition  or
unenforceability   in  any   jurisdiction   shall  not   invalidate   or  render
unenforceable such provision in any other jurisdiction.
