event taking such action as is  necessary to cause the security  interest in the
Collateral to continue to be perfected.

           (f) Not change  its name,  identity  or  corporate  structure  in any
manner  which  might  make any  financing  or  continuation  statement  filed in
connection with this Agreement misleading within the meaning of Section 9-402 of

respect thereto as noted in paragraph 5(b) above.

           (j)  Defend  the  Collateral  against  all  claims,  liens,  security

effective  unless the same shall be in writing and signed by Secured Party,  and
then such waiver or consent shall be effective only in the specific instance and
for the purpose for which given.

           (b) No notice or demand on Debtor in any case shall entitle Debtor to
any  other  or  further  notice  or  demand  in  the  same,   similar  or  other
circumstances.

           (c) Debtor hereby waives presentment,  notice of dishonor and protest
of all instruments  included in or evidencing the liability of Debtor in respect
of the  Obligations  or the Collateral and any and all other notices and demands
whatsoever, whether or not relating to such instruments.

           (d) The  Obligations  shall not be  affected  by (i) the  failure  of
Secured  Party to assert any claim or demand or to  enforce  any right or remedy
against  Debtor;  (ii) any extension or renewal  thereof;  (iii) any rescission,
waiver,  amendment or  modification  of any of the terms or  provisions  of this
Agreement or of any other agreement;  or (iv) the release of any collateral held
by Secured Party for the Obligations or any of them.

     20.  SEVERABILITY.  In case any one or more of the provisions  contained in
this Agreement should be determined by a court of law to be invalid,  illegal or
unenforceable in any respect,  the validity,  legality and enforceability of the
remaining  provisions  contained  herein  shall  not in any way be  affected  or
impaired thereby.

Agreement  or the subject  matter  hereof  brought by any party  hereto or their
respective successors or assigns; and

           (b) waives, and agrees not to assert, by way of motion, as a defense,
or otherwise,  in any such suit, action or proceeding,  any claim that it is not
subject  personally  to the  jurisdiction  of the above named  courts,  that its
property is exempt or immune from attachment or execution, that the suit, action
or proceeding is brought in an inconvenient  forum,  that the venue of the suit,
action or  proceeding is improper or that this  Agreement or the subject  matter
hereof may not be enforced in or by such court.

           (c) waives any right to jury trial and any  offsets or  counterclaims
in any such action,  suit or proceeding  (other than compulsory  counterclaims);
and

           (d) consents to service of process by registered  mail at the address
to which notices are to be given.
